35,069,967 | Flask-Migrate and Migrations in General | I'm relatively new to flask, python, and coding overall so please bear with me if you have the time. I'm trying to understand migrations and have some questions regarding the topic.
I'm working on a web-based asset management app, and I've had some modest success thus far. I've implemented a page that iterates through all my assets (rows) and displays them in a form with their associated row values (horsepower, voltage etc.) I've implemented a page that takes form data and adds it to the database. I've implemented a page that lets you filter all your assets by some of their values (horsepower, voltage etc.) and displays the result, as well as a search by primary_key (Asset Tag) bar in the header. To be honest so far I'm quietly impressing myself :).
Flask is great because when I was getting started and watching a few tutorial playlists I found it easier to learn than Django. There was much less overhead / pre-written code and I actually knew what each line of code was doing, and I felt I was really grasping the operation of my application in its entirety. Anyways this is all besides the point.
What I'm looking to implement now is something I feel the need to get some opinions on as I have not found much of anything regarding it online. I'd like for my customers to be able to add / remove tables, and table columns and rows. From the reading I have done I know that making schema changes is going to require migrations, so adding in that functionality would require something along the lines of writing a view that takes form data and inserts it into a function that then invokes a method of Flask-Migrate, or maybe something directly into Flask-Migrate itself?
The thing is, even if I manage to build something like this, don't migrations build the required separate scripts and everything that goes along with that each time something is added or removed? Is that a practical solution for something like this, where 10 or 20 new tables might be added from the default / shipped database?
Also, if I'm building in a functionality that allows users to add columns to a table, it will have to modify that tables class. I'm unsure if that's even possible, or a safe idea?
I may also be looking at solving this the wrong way entirely. In that case I'd really appreciate it if someone could help me out, and at least get me pointed in the right direction.
TLDR;
Can you take form data and change database schema? Is it a good idea? Is there a downside to many migrations from a 'default' database? | <python><flask><sqlalchemy><alembic><flask-migrate> | 2016-01-28 19:11:15 | LQ_EDIT |

<p>There are many more lines, but this is just an example of how the error log is currently formatted.The posper errors header only appears once, and subsequent lines are simply more errors.</p>
<p>What I need to do with this script is insert errors into the table I have created with the fields: client_name, timestamp, error_message and error_from (either Posper or a something else. In the example above it is posper). </p>
<p>So how exactly am I supposed to break down the data on each line, assign it to individual mySQL fields, and then insert it into the database? Keep in mind the log file will have many lines, so it will have to execute multiple times. I have already set up the table with the appropriate fields.</p>

<p>I have tried variations on all of this</p>
<pre><code>spyOn(window, 'setTimeout').and.callFake(()=>{});
spyOn(global, 'setTimeout').and.callFake(()=>{});
spyOn(window, 'clearTimeout').and.callThrough();
clock = jasmine.clock();

expect(global.setTimeout).toHaveBeenCalled(); // nope
expect(window.clearTimeout).toHaveBeenCalled(); // no again
expect(clock.setTimeout).toHaveBeenCalled(); // and no
</code></pre>
<p>In every case, I can confirm that <code>setTimeout</code> and <code>clearTimeout</code> have been invoked in <code>runMyCode</code>, but instead I always get <code>Expected spy setTimeout to have been called.</code></p>
<p>For <code>window</code>, clearly this is because the test and the runner (the Karma window) are in different frames (so why should I expect anything different). But because of this, I can't see any way to confirm that these global functions have been invoked.</p>
<p>I know that I can use <code>jasmine.clock()</code> to confirm that timeout/interval callbacks have been invoked, but it looks like I can't watch <code>setTimeout</code> itself. And confirming that <code>clearTimeout</code> has been called simply isn't possible.</p>
<p>At this point, the only thing I can think of is to add a separate layer of abstraction to wrap <code>setTimeout</code> and <code>clearTimeout</code> or to inject the functions as dependencies, which I've done before, but I think is weird.</p>

35,081,194 | Why is IEnumerable(of T) not accepted as extension method receiver | <p>Complete <strong>question</strong> before code:</p>
<p>Why is <code>IEnumerable<T></code> <code>where T : ITest</code> not accepted as receiver of an extension method that expects <code>this IEnumerable<ITest></code>?</p>
<p>And now the <strong>code</strong>:</p>
<p>I have three types:</p>
<pre><code>public interface ITest { }
public class Element : ITest { }
public class ElementInfo : ITest { }
</code></pre>
<p>And two extension methods:</p>
<pre><code>public static class Extensions
{
public static IEnumerable<ElementInfo> Method<T>(
this IEnumerable<T> collection)
where T : ITest
{
β return collection.ToInfoObjects();
}
public static IEnumerable<ElementInfo> ToInfoObjects(
this IEnumerable<ITest> collection)
{
return collection.Select(item => new ElementInfo());
}
}
</code></pre>
<p>The compiler error I get (on the marked line):</p>
<blockquote>
<p><code>CS1929</code> : <code>'IEnumerable<T>'</code> does not contain a definition for <code>'ToInfoObjects'</code> and the best extension method overload <code>'Extensions.ToInfoObjects(IEnumerable<ITest>)'</code> requires a receiver of type <code>'IEnumerable<ITest>'</code></p>
</blockquote>
<p>Why is this so? The receiver of the <code>ToInfoObjects</code> extension method is an <code>IEnumerable<T></code> and by the generic type constraint, <code>T</code> must implement <code>ITest</code>. </p>
<p><strong>Why is then the receiver not accepted</strong>? My guess is the covariance of the <code>IEnumerable<T></code> but I am not sure.</p>
<p>If I change <code>ToInfoObjects</code> to receive <code>IEnumerable<T> where T : ITest</code>, then everything is ok.</p>

I am passing the strings into my html page using jinja2, and trying to parse them JSON objects in javascript.
<script type="text/javascript">
function parseLine(x){
var obj = JSON.parse(x);
document.write(obj.timestamp1);
}
I am getting this error:
SyntaxError: JSON.parse: expected property name or '}' at line 1 column 2 of the JSON data

If I use a dummy string, surrounded by single quotes: '{"test": "1234"}' it works fine.

35,091,412 | Jenkins build monitor wall without manual login | <p>I'm trying to create a completely automatized Jenkins status screen for our office wall with a Raspberry Pi. I was able to configure the Pi to show a browser with a specific URL on the TVs as well as configuring the <a href="https://wiki.jenkins-ci.org/display/JENKINS/Build+Monitor+Plugin">Build Monitor Plugin in Jenkins</a> with our build jobs.</p>
<p>Our Jenkins uses matrix-based security, so I created separate <code>raspberry</code> user with the required privileges. (After logging in manually the wall plugin is shown properly.)</p>
<p>I can see a valid HTTP answer with the following command:</p>
<pre><code>curl "http://raspberry:0b45...06@localhost:8080/view/wall1/"
</code></pre>
<p><code>0b45...06</code> is the API Token of the <code>raspberry</code> Jenkins user. (From
<code>http://localhost:8080/user/raspberry/configure</code>)</p>
<p>Unfortunately this URL scheme does not work in graphical browsers. I've also tried the token parameter without success:</p>
<pre><code>$ curl "http://localhost:8080/view/wall1/?token=0b45...06"
<html><head>...</head><body ...>

35,091,783 | Can't delete Parenthesis in IntelliJ/Cursive | <p>I'm using IntelliJ/Cursive to write Clojure.
I found out that the only way to erase parenthesis is to totally erase the content inside them, and only then, the parenthesis can be deleted.
For example, let's say that I have the following code: </p>
<pre><code>(list)
</code></pre>
<p>and I want to delete only the opening parenthesis. Once I hit backspace on the opening parenthesis, the IDE ignores this act. Only when I erase the word "list", the parenthesis can be deleted. </p>

35,092,183 | Webpack plugin: how can I modify and re-parse a module after compilation? | <p>I'm working on a webpack plugin and can't figure out how to modify a module during the build. What I'm trying to do:</p>
<ul>
<li>Collect data via a custom loader (fine)</li>
<li>After all modules have been loaded, collect data gathered by my loader (fine)</li>
<li>Insert code I generate into an existing module in the build (doing this as described below, not sure if it's the best way)</li>
<li>'update' that module so that the code I added gets parsed and has its 'require's turned into webpack require calls (can't figure out how to do this correctly)</li>
</ul>
<p>Currently I'm hooking into 'this-compilation' on the compiler, then 'additional-chunk-assets' on the compilation. Grabbing the first chunk (the only one, currently, as I'm still in development), iterating through the modules in that chunk to find the one I want to modify. Then:</p>
<ul>
<li>Appending my generated source to the module's _cachedSource.source._source._value (I also tried appending to the module's ._source._value)</li>
<li>setting the ._cachedSource.hash to an empty string (as this seems to be necessary for the next step to work)</li>
<li>I pass the module to .rebuildModule() </li>
</ul>
<p>It looks like rebuildModule should re-parse the source, re-establish dependencies, etc. etc., but it's not parsing my require statements and changing them to webpack requires. The built file includes my modified source but the require('...') statements are unmodified.</p>
<p>How can I make the module I modified 'update' so that webpack will treat my added source the same as the originally parsed source? Is there something I need to do in addition to rebuildModule()? Am I doing this work too late in the build process? Or am I going about it the wrong way?</p>

35,097,193 | Can I bundle the Visual Studio 2015 C++ Redistributable DLL's with my application? | <p>I've built a C++ application using Microsoft Visual Studio 2015 Community Edition. I'm using Advanced Installer to make sure that the <a href="https://www.microsoft.com/en-us/download/details.aspx?id=48145">Visual C++ Redistributable for Visual Studio 2015</a> is a prerequisite.</p>
<p>However, the redistributable's installer isn't perfect. Some of my users have reported that the redistributable installer hangs, or it fails to install when it says it does, and then users get the "This program can't start because MSVCP140.dll is missing from your computer" error.</p>
<p>According to Microsoft, <a href="https://msdn.microsoft.com/en-us/library/ms235299.aspx">I can now package the redistributable DLLs along with my application, though they don't recommend it:</a></p>
<blockquote>
<p>To deploy redistributable Visual C++ files, you can use the Visual C++ Redistributable Packages (VCRedist_x86.exe, VCRedist_x64.exe, or VCRedist_arm.exe) that are included in Visual Studio. ... It's also possible to directly install redistributable Visual C++ DLLs in the application local folder, which is the folder that contains your executable application file. For servicing reasons, we do not recommend that you use this installation location.</p>
</blockquote>
<p>There are 4 files in <code>C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x64\Microsoft.VC140.CRT</code>. Does that mean I just need to copy them to my application's directory during the install process?</p>
<ul>
<li>MyApp.exe</li>
<li>concrt140.dll</li>
<li>msvcp140.dll</li>
<li>vccorlib140.dll</li>
<li>vcruntime140.dll</li>
</ul>
<p>Is this OK to do? Do I need to show a license? Why aren't more people doing this instead of requiring yet another preinstall of the redistributable?</p>

35,101,099 | How do I safely remove items from an array in a for loop? | <p>Full disclose, this is for a homework question:</p>
<blockquote>
<p>It should have a private property of type [Circle]. An array of circles.
The method should remove any circles that have a radius larger than
the minimum requirement, and smaller than the max requirement.</p>
</blockquote>
<p>It seems obvious that I should use <code>removeAtIndex()</code> to remove array items that don't meet a condition determined in the loop. However, many have pointed out before the perils of removing items in a loop because of what I guess is a "iterator/index mismatch".</p>
<p>Ultimately I ended up creating an empty array and using <code>.append()</code> to push the values that meet the "good" condition to a <code>filteredCircles</code> array, but I can't help but to feel that this this doesn't meet the criteria for the assignment.</p>
<p>Is there a solution that actually removes the items from the array in a loop?</p>

35,104,097 | How to install psycopg2 with pg_config error? | <p>I've tried to install psycopg2 (PostgreSQL Database adapater) from <a href="http://initd.org/psycopg/" rel="noreferrer">this site</a>, but when I try to install after I cd into the package and write </p>
<pre><code>python setup.py install
</code></pre>
<p>I get the following error: </p>
<pre><code>Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
</code></pre>
<p>I've also tried 'sudo pip install psycopg2' and I got the same message. </p>
<p>After reading through the <a href="http://initd.org/psycopg/docs/" rel="noreferrer">docs</a>, it asks to look at the setup.cfg file (which is below): </p>
<pre><code>[build_ext]
define=
# PSYCOPG_DISPLAY_SIZE enable display size calculation (a little slower)
# HAVE_PQFREEMEM should be defined on PostgreSQL >= 7.4
# PSYCOPG_DEBUG can be added to enable verbose debug information
# "pg_config" is required to locate PostgreSQL headers and libraries needed to
# build psycopg2. If pg_config is not in the path or is installed under a
# different name uncomment the following option and set it to the pg_config
# full path.
#pg_config=
# Set to 1 to use Python datetime objects for default date/time representation.
use_pydatetime=1
# If the build system does not find the mx.DateTime headers, try
# uncommenting the following line and setting its value to the right path.
#mx_include_dir=
# For Windows only:
# Set to 1 if the PostgreSQL library was built with OpenSSL.
# Required to link in OpenSSL libraries and dependencies.
have_ssl=0
# Statically link against the postgresql client library.
#static_libpq=1
# Add here eventual extra libraries required to link the module.
#libraries=
</code></pre>
<p>However, I'm not sure if I'm suppose to edit this file, since the documentation states the following: </p>
<pre><code>then take a look at the setup.cfg file.
Some of the options available in setup.cfg are also available as command line arguments of the build_ext sub-command. For instance you can specify an alternate pg_config version using:
$ python setup.py build_ext --pg-config /path/to/pg_config build
Use python setup.py build_ext --help to get a list of the options supported.
</code></pre>
<p>I've gotten the list of options supported but I'm not sure where to go from there</p>

35,106,022 | Adding buttons to toolbar programmatically in swift | <p>I'm having a hard time adding a button to the toolbar in swift, below you can see an image of the toolbar that I'm after, unfortunately even though I have it designed in my Storyboard file, it doesn't show up when setting the toolbar to be visible.</p>
<p>The way that I have designed this is two items, the first being a <code>flexable space</code> element, and the second being an <code>add</code> element. It looks like this:</p>
<p><a href="https://i.stack.imgur.com/tPFXA.png" rel="noreferrer"><img src="https://i.stack.imgur.com/tPFXA.png" alt="enter image description here"></a></p>
<p>Here's the code that I've used to attempt to replicate this in code:</p>
<pre><code>self.navigationController?.toolbarHidden = false
self.navigationController?.toolbarItems = [UIBarButtonItem]()
self.navigationController?.toolbarItems?.append(
UIBarButtonItem(barButtonSystemItem: .FlexibleSpace, target: self, action: nil)
)
self.navigationController?.toolbarItems?.append(
UIBarButtonItem(barButtonSystemItem: .Add, target: self, action: "onClickedToolbeltButton:")
)
</code></pre>
<p>As you can see I'm setting the toolbar to be visible, initializing (and clearing) the toolbarItems array of UIBarButtonItem, and then adding two UIBarButtonItem's to the array, in the proper order.</p>
<p>However, the toolbelt remains empty, why is this? </p>

35,106,118 | What is the best way to call into Swift from C? | <p>Calling into C from Swift is pretty simple, however I'm looking into making a bi-directional wrapper in C, so my C has to call Swift functions.</p>
<p>Right now, I can do this by declaring function pointers in C, and having my C functions call them after the Swift side has set them up to call code in Swift.</p>
<p>My C header file:</p>
<pre><code>typedef void (*callback_t)(void);
void callBackIntoSwift( callback_t cb );
</code></pre>
<p>My C implementation file:</p>
<pre><code>#include "stuff.h"
#include <stdio.h>
void callBackIntoSwift( callback_t cb )
{
printf( "Will call back into Swift\n" );
cb();
printf( "Did call back into Swift\n" );
}
</code></pre>
<p>After including my C header file in the bridging header, I can do the following on the Swift side:</p>
<pre><code>let cb: callback_t = {
someKindOfSwiftFunction()
}
callBackIntoSwift( cb )
</code></pre>
<p>Or even:</p>
<pre><code>callBackIntoSwift {
someKindOfSwiftFunction()
}
</code></pre>
<p>Is there a better way to do this, where function pointers and callbacks are not needed? I'd like to let the C-side call <code>someKindOfSwiftFunction</code> directly β¦ but when I try to apply <code>@convention (c)</code> to function declarations I get the message that the attribute can only be applied to types, and not declarations.</p>
<p>Any ideas or codebases in e.g. Github I can take a look at?</p>

35,106,467 | How can I add broad image recognition to a mobile app? | <p>I'm working on an Android app (though eventually I'll want to do the same thing on iOS) and I'm looking to build an image recognition feature into it. The user would snap a picture, then this component of the app would need to figure out what that image is, whether it's a bowling ball, a salad, a book, you name it. It would also be helpful if it could figure out roughly how big the object in question is, though I imagine the camera focus values could help with that. The objects in question would not be moving.</p>
<p>I've heard of neural networks being used, but I'm not sure how this could be implemented, especially since I want to be able to recognize a very wide range of objects. I highly doubt this sort of processing could happen natively on a phone either. What are some solutions to this problem?</p>

35,106,811 | Unit Testing Strategy, Ideal Code Coverage Baseline | <p>There's still not much information out there on the XCode7 and Swift 2.0 real-world experiences from a unit testing and code coverage perspective. </p>
<p>While there're plenty of tutorials and basic how-to guides available, I wonder what is the experience and typical coverage stats on different iOS teams that actually tried to achieve a reasonable coverage for their released iOS/Swift apps. I specifically wonder about this:</p>
<p>1) while code coverage percentage doesn't represent the overall quality of the code base, is this being used as an essential metric on your team? If not, what is the other measurable way to assess the quality of your code base?</p>
<p>2) For a bit more robust app, what is your current code coverage percentage? (just fyi, we have hard time getting over 50% for our current code base)</p>
<p>3) How do you test things like:</p>
<ul>
<li>App life-cycle, AppDelegate methods</li>
<li>Any code related to push/local notifications, deep linking</li>
<li>Defensive programming practices, various piece-of-mind (hardly reproducible) safe guards, exception handling etc.</li>
<li>Animations, transitions, rendering of custom controls (CG) etc.</li>
<li>Popups or Alerts that may include any additional logic</li>
</ul>
<p>I understand some of the above is more of a subject for actual UI tests, but it makes me wonder:</p>
<ul>
<li>Is there a reasonable way to get the above tested from the UTs perspective? Should we be even trying to satisfy an arbitrary minimal code coverage percentage with UTs for the whole code base or should we define that percentage off a reasonably achievable coverage given the app's code base?</li>
<li>Is it reasonable to make the code base more inflexible in order to achieve higher coverage? (I'm not talking about a medical app where life would be in stake here)</li>
<li>are there any good practices on testing all the things mentioned above, other than with UI tests?</li>
</ul>
<p>Looking forward to a fruitful discussion.</p>
