SQL Query so as to match content on 2 fields in database : i have a table #__newtoys_variants having many fields of which id and v_prod_id are there.
Now although id is unique - the v_prod_id is product id
for instance
id v_prod_id price
1 7 200
2 7 220
3 1 250
4 1 270
5 2 300
6 10 350
7 9 220
8 7 195
Now i intend that 404 error should be displayed in front end - if the id and v_prod_id is not matched in front end
Actually this is my url structure
example.com/index.php?option=com_newtoys&id=2&vid=7
here id value is extracted from #__newtoys_variants and vid is v_prod_id as extracted from #__newtoys_variants
In case a user changes url to say
example.com/index.php?option=com_newtoys&id=2&vid=1
then want 404 error to be displayed in front end
Here is Table Database
[![enter image description here][1]][1]
Can any one help on it to achieve same
Here is a brief function - unsure what exactly should be in sql query so that id & v_prod_id should be matched and in case result is zero then error message can be displayed
function loadProduct($id ,$vid){
$mainframe =JFactory::getApplication();
$option = JRequest::getCmd('option');
$db =JFactory::getDBO();
global $Itemid;
$sql = "";
$db->setQuery($sql);
if ($rows = $db->loadObjectlist()) {
return $rows[0];
} else {
if ($db->getErrorNum()) {
JError::raiseError(500, "Something went horribly wrong, the query returned the error ". $db->getErrorMsg());
} else {
JError::raiseError(404, "404, Page does not Exists ". $db->getErrorMsg());
}

Why will my remove function find strings but not ints? : <p>We are working on generics which requires us to have an array of AnyType (the driver implements an array of strings then integers). One of the functions is a boolean function called 'remove' which finds 'x' and removes it, then it returns true. It has no issues finding and removing a string but can't seem to find ints. Why is this?</p>
<p>the code is</p>
<pre><code>public boolean remove(AnyType x)
{
for(int i = 0; i < length; i++)
{
if(arr[i] == x)
{
for(int j = i; j < length - 1; j++)
{
arr[j] = arr[j + 1];

pandas multiply using dictionary values across several columns : <p>Given the following dataframe:</p>
<pre><code>import pandas as pd
df = pd.DataFrame({
'a': [1,2,3,4,5],
'b': [5,4,3,3,4],
'c': [3,2,4,3,10],
'd': [3, 2, 1, 1, 1]
})
</code></pre>
<p>And the following list of parameters:</p>
<pre><code>params = {'a': 2.5, 'b': 3.0, 'c': 1.3, 'd': 0.9}
</code></pre>
<p>Produce the following desired output:</p>
<pre><code> a b c d output
0 1 5 3 3 24.1
1 2 4 2 2 21.4
2 3 3 4 1 22.6
3 4 3 3 1 23.8
4 5 4 10 1 38.4
</code></pre>
<p>I have been using this to produce the result:</p>
<pre><code>df['output'] = [np.sum(params[col] * df.loc[idx, col] for col in df)
for idx in df.index]
</code></pre>
<p>However, this is a very slow approach and I'm thinking there has to be a better way using built-in pandas functionality.</p>
<p>I also thought of this:</p>
<pre><code># Line up the parameters
col_sort_key = list(df)
params_sorted = sorted(params.items(), key=lambda k: col_sort_key.index(k[0]))
# Repeat the parameters *n* number of times
values = [v for k, v in params_sorted]
values = np.array([values] * df.shape[0])
values
array([[ 2.5, 3. , 1.3, 0.9],
[ 2.5, 3. , 1.3, 0.9],
[ 2.5, 3. , 1.3, 0.9],
[ 2.5, 3. , 1.3, 0.9],
[ 2.5, 3. , 1.3, 0.9]])
# Multiply and add
product = df[col_sort_key].values * values
product
array([[ 2.5, 15. , 3.9, 2.7],
[ 5. , 12. , 2.6, 1.8],
[ 7.5, 9. , 5.2, 0.9],
[ 10. , 9. , 3.9, 0.9],
[ 12.5, 12. , 13. , 0.9]])
np.sum(product, axis=1)
array([ 24.1, 21.4, 22.6, 23.8, 38.4])
</code></pre>
<p>But that seems a bit convoluted! Any thoughts on a native pandas try?</p>

Linkedin: Sharing URL Summary not appearing : <p>I'm not sure if this is new behaviour or if it didn't work at all.
So I'm using the LinkedIn Customized URL feature, you can look it up <a href="https://developer.linkedin.com/docs/share-on-linkedin" rel="noreferrer">here</a>. The URL looks like this:</p>
<p><code>https://www.linkedin.com/shareArticle?mini=true&url=http://developer.linkedin.com&title=LinkedIn%20Developer%20Network&summary=My%20favorite%20developer%20program&source=LinkedIn</code></p>
<p>Once I share the URL the provided <code>summary</code> is not shown in the post preview:</p>
<p><a href="https://i.stack.imgur.com/vuf0z.png" rel="noreferrer"><img src="https://i.stack.imgur.com/vuf0z.png" alt="LinkedIn Screenshot containing a shared post sample"></a></p>
<p>So I tried with other services like Youtube, Reddit etc. and all posts <strong>do not</strong> include the provided summary.</p>
<p>Unfortunately I can't provide you the open-graph tags I used on my site as it's running in a corporate environment and I'm not sure if I can provide these snippets as of now.</p>
<p>However, running linkedin's <a href="https://www.linkedin.com/post-inspector/" rel="noreferrer">Post Inspector</a> shows that it detects my summary without problems:</p>
<p><a href="https://i.stack.imgur.com/fsczt.png" rel="noreferrer"><img src="https://i.stack.imgur.com/fsczt.png" alt="PostInspector Output"></a>
<em>Values are in German if anyone wonders...</em></p>
<p>So my quick and fairly simple questions, which might be answered in a comment as well, are:</p>
<p>Did linkedin change something on their side?
Is there some other undocumented property which neither youtube nor me included in the customized URL and therefore the summary does not show up?
Is there any post from linkedin developers which note this change?
Was it like that all the time or is it just a temporary thing? </p>

Angular Material Datepicker: Change event not firing when selecting date : <p>I'm using Angular and Angular Material's Datepicker. Everything is working fine for the most part, however I added a <code>(change)</code> event that is only working when the user manually types in a date. It does not get triggered when the user clicks on a date from the datepicker popup. To be clear, the value for <code>date</code> does in fact change when the user clicks on a date, it is just the <code>(change)</code> event, and ultimately my <code>updateCalcs()</code> function that for some reason doesn't get triggered. How can I trigger an event when the user clicks on a date from the datepicker?</p>
<pre><code><md-input-container>
<input mdInput [mdDatepicker]="datePicker" placeholder="Choose Date" name="date" [(ngModel)]="date" (change)="updateCalcs()" required>

<p>After a sign in attempt, the CheckAuth <em>(which checks whether a user is signed in or not and then opens home screen or sign up screen accordingly)</em> is opened with this code: </p>
<pre><code> void _signIn() async {
await _auth
.signInWithEmailAndPassword(
email: _userEmail.trim(), password: _userPassword.trim())
.then((task) {
// go to home screen
if (task.getIdToken() != null) {
setState(() {
Navigator.pushReplacement(
context,
new MaterialPageRoute(
builder: (BuildContext context) => new CheckAuth()));
});
} else {
print("Authentication failed");
}
});
}
</code></pre>
<p>Problem: I can successfully sign in to the app, but if I tap back button after I sign in, it goes back to the sign in screen (while I expect it to exit from the app).</p>
<p>Question: <strong>How to move from one screen to another in Flutter without the way back?</strong> </p>
<p>Do I need to somehow delete the navigator history? Or don't use navigator at all? I tried <em>Navigator.replace</em> method, but it didn't seem to work.</p>

AWS Cognito; unauthorized_client error when hitting /oauth2/token : <p>Steps taken so far:</p>
<ul>
<li>Set up new user pool in cognito</li>
<li>Generate an app client with <em>no secret</em>; let's call its id <code>user_pool_client_id</code></li>
<li>Under the user pool client settings for <code>user_pool_client_id</code> check the "Cognito User Pool" box, add <code>https://localhost</code> as a callback and sign out url, check "Authorization Code Grant", "Implicit Grant" and everything under "Allowed OAuth Scopes"</li>
<li>Create a domain name; let's call it <code>user_pool_domain</code></li>
</ul>
<p>Create a new user with a username/password</p>
<p>Now, I can successfully go to:</p>
<p><code>https://{{user_pool_domain}}.auth.us-east-2.amazoncognito.com/oauth2/authorize?response_type=code&client_id={{user_pool_client_id}}&redirect_uri=https%3A%2F%2Flocalhost</code></p>
<p>This presents me with a login page and I am able to login as my user which returns me to <code>https://localhost/?code={{code_uuid}}</code></p>
<p>I then try the following:
<code>
curl -X POST https://{{user_pool_domain}}.auth.us-east-2.amazoncognito.com/oauth2/token -H 'Content-Type: application/x-www-form-urlencoded' -d 'grant_type=authorization_code&redirect_uri=https%3A%2F%2Flocalhost&code={{code_uuid}}&client_id={{user_pool_client_id}}'
</code></p>
<p>However, this just returns back the following:
<code>
{"error":"unauthorized_client"}
</code></p>
<p>The <a href="https://docs.aws.amazon.com/cognito/latest/developerguide/token-endpoint.html" rel="noreferrer">token endpoint docs</a> say that <code>unauthorized_client</code> is because "Client is not allowed for code grant flow or for refreshing tokens." which is confusing because I checked the boxes allowing the client to use the code grant flow.</p>

My problem is the goto command, I use two variables for the horizontal and vertical inputs but only one of them works at a time, I need them both to work.
Any help would be appreciated.

Using Django URLs with AngularJs routeProvider : <p>for a project, I am using Django on the back-end and AngularJs on the front end.</p>
<p>Basically, what I want is to run the Angular app only when the url starts with <code>projectkeeper/</code>.</p>
<p>In other words, lets say my website is example.com. I want the angular app to run for the URLs <code>example.com/projectkeeper/dashboard/</code>, <code>example.com/projectkeeper/projects/</code> and so on, but not on <code>example.com/about/</code>.</p>
<p>Hope I have made myself clear. Anyway, in order to do this, I am doing the following with my code:</p>
<p><strong>urls.py</strong></p>
<pre><code>urlpatterns = [
url(r'^projectkeeper/$', TemplateView.as_view(template_name='base.html')),
]
</code></pre>
<p>In the template <strong>base.html</strong>, I refer to my angular app obviously. For the angular routing, I have done the following:</p>
<pre><code>myapp.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/dashboard/', {
title: 'Dashboard',
controller : 'DashboardController',
templateUrl : 'static/app_partials/projectkeeper/dashboard.html'
})
.otherwise({ redirectTo : '/' });
}]);
</code></pre>
<p>So, ideally, what I thought was that going to <code>example.com/projectkeeper/#/dashboard/</code> would run the DashboardController from my angular app. However, this is not the case, I only get an empty page which means the routing was incorrect.</p>
<p>Any solutions to this? As I said before, I want is to run the Angular app <strong>only</strong> when the url starts with <code>projectkeeper/</code>.</p>

How to show part of next/previous card RecyclerView : <p>What is the best strategy to achieve this feature:</p>
<p><a href="https://i.stack.imgur.com/IKaKq.png" rel="noreferrer"><img src="https://i.stack.imgur.com/IKaKq.png" alt="enter image description here"></a></p>
<p>I Have a horizontal RecyclerView with cards.
Each card will fulfil the entire screen, but I want it to show part of the next card and previous one if it has more than one item.</p>
<p>I know I can achieve this by setting my card <code>android:layout_width</code> at the adapter to have a specific DP like 250dp instead of <code>match_parent</code>.
But it doesn't look like a proper solution.</p>
<p>This is my code:</p>
<p>Activity with RecyclerView:</p>
<pre><code> class ListPokemon : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val items = createListPokemons()
recyclerView.adapter = PokemonAdapter(items)
recyclerView.layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)
recyclerView.setHasFixedSize(true)
val pagerSnapHelper = PagerSnapHelper()
pagerSnapHelper.attachToRecyclerView(recyclerView)
}
private fun createListPokemons(): List<Pokemon> {
val pokemons = ArrayList<Pokemon>()
pokemons += createPokemon("Pikachu")
pokemons += createPokemon("Bulbasaur")
pokemons += createPokemon("Charmander")
pokemons += createPokemon("Squirtle")
return pokemons
}

Index Bounds on Mongo Regex Search : <p>I'm using MongoDB, and I have a collection of documents with the following structure:</p>
<pre><code>{
fName:"Foo",
lName:"Barius",
email:"fbarius@example.com",
search:"foo barius"
}
</code></pre>
<p>I am building a function that will perform a regular expression search on the <code>search</code> field. To optimize performance, I have indexed this collection on the search field. However, things are still a bit slow. So I ran an <code>explain()</code> on a sample query:</p>
<pre><code>db.Collection.find({search:/bar/}).explain();
</code></pre>
<p>Looking under the winning plan, I see the following index bounds used:</p>
<pre><code>"search": [
"[\"\", {})",
"[/.*bar.*/, /.*bar.*/]"
]
</code></pre>
<p>The second set makes sense - it's looking from anything that contains bar to anything that contains bar. However, the first set baffles me. It appears to be looking in the bounds of <code>""</code> inclusive to <code>{}</code> exclusive. I'm concerned that this extra set of bounds is slowing down my query. Is it necessary to keep? If it's not, how can I prevent it from being included?</p>

About my Java Code Function : http://jsfiddle.net/MrBigglesWorth/Lwxoeyyp/408/ This code is suppose to save the checkboxs I've ticked after clicking the Save button. Currently that is working but only for one Button. I'm trying to get it to work on all of them to allow me to check them all and save and I plan on adding more than 9 buttons.
Trying to pass through ID's through a function. Not sure how to do it though.
when I click save on it with more than one of the boxs checked, it only keeps the first one checked cause that has the ID box1 is what the javascript is calling in the function. What Code do I need and how do I go about using this function for each btn. I was thinking of a onclick with .this might work but I am not sure.

What is the default encoding for source files in visual studio 2017 : <p>It seems visual studio 2017 always saves new files as UTF8-BOM.
It also seems this was not the case with earlier versions of visual studio, but i could not find any documentation. </p>
<p>Also there has been an option "Advanced Save Options\Encoding" which did allow to change the encoding of newly saved files which is missing in VS2017.</p>
<p>Questions:</p>
<ul>
<li>Are all files types saved with UTF8-BOM encoding in VS2017</li>
<li>Is it possible to configure the encoding for new files in VS2017</li>
<li>Will VS2017 change the encoding of "old" files which don't have UTF8-BOM</li>
<li>Is there any documentation about this topic</li>

Dagger 2 Singleton Component Depend On Singleton : <p>I've got a strange problem here, and I'm not quite sure why what I'm doing isn't allowed. I've got the following modules:</p>
<pre><code>@Module
public final class AppModule {
private Context mContext;
@Provides
@Singleton
@AppContext
public Context provideContext() { return mContext; }
}
@Module
public final class NetModule {
@Provides
@Singleton
public OkHttpClient provideOkHttp() {
return new OkHttpClient.Builder().build();
}
}
</code></pre>
<p>For various reasons, I don't want to have these two modules in the same component (basically due to my project structure). So I tried to create the following components:</p>
<pre><code>@Singleton
@Component(modules = AppModule.class)
public interface AppComponent {
@AppContext Context appContext();
}
@Singleton
@Component(dependencies = AppComponent.class, modules = NetModule.class)
public interface NetComponent {
Retrofit retrofit();
}
</code></pre>
<p>But when I try to compile this, I get the following error message:</p>
<p><code>Error:(12, 1) error: This @Singleton component cannot depend on scoped components:
@Singleton com.myapp.service.dagger.AppComponent</code></p>
<p>I understand why depending on <em>different</em> scopes would be bad and disallowed. But why is Singleton depends-on Singleton not allowed? This feels like it should work, since all I'm doing is declaring sibling components. What am I missing?</p>

Unable to load the mojo 'test' - org.apache.maven.plugins:maven-surefire-plugin:3.0.0-M1:test : <p>I am building my apps with Maven-3 and i guess after auto-refresh of maven-surefire-plugin to 3.0.0-M1 i am not able to do build and getting the below error. </p>
<p>As a initial step, I have cleared the directory /org/apache/maven in my repository however still i am facing the issue. Can anyone advise. Note - if i am downgrading the surefire plugin to 2.x then I am able to build it.</p>

converting string value from text field to integer in Swift 3 &/or Swift 4 : I'm really new to Swift and am having problems with the conversion of a string (entered in a text field) to an integer.
I'm trying to create a small calculation app in XCode 8 (I was following a tutorial on YouTube but it's old).
My app has 3 text fields, a label (that is meant to display the result), and a button to start the calculation.
I'm currently using Swift 3 but if someone could give me the answer for doing it in Swift 3 & Swift 4 I'd be grateful.
Here's the code:
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var valueA: UITextField!
@IBOutlet weak var valueB: UITextField!
@IBOutlet weak var valueC: UITextField!
@IBOutlet weak var result: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func calculateTotal(_ sender: Any) {
var a:Int? = Int(valueA.text)
var b:Int? = Int(valueB.text)
var c:Int? = Int(valueA.text)
var answer = a! * b! * c!
}
}

c# How can i replace backslash in a string? : <p>I am working on a c# project and have some strings like this </p>
<p><strong>first string</strong></p>
<pre><code>"[\"2018\\/02\\/12\",[\"Test1\",\"Test2\",\"Test3\",\"Test4\"]]"
</code></pre>
<p>But this string format is not not suitable for my application. I want to change first string to this :</p>
<p><strong>second string</strong></p>
<pre><code>2018-02-12,"Test1","Test2","Test3","Test4"
</code></pre>
<p>I've done some of it, but I'm having trouble getting a backslash. Actually backslash did not changed.</p>
<p><strong>my code :</strong></p>
<pre><code>string MyString = "[\"2018\\/02\\/12\",[\"Test1\",\"Test2\",\"Test3\",\"Test4\"]]";
MyString = MyString.Replace("[", "").Replace("]", "").Replace("\\", "");
</code></pre>
<p>How can I get the second string?</p>

Hash an integer in Python to match Oracle's STANDARD_HASH : <p>In Oracle, my data has been hashed by passing an integer into `STANDARD_HASH' as follows. How can I get the same hash value using Python?</p>
<p>Result in Oracle when an integer passed to STANDARD_HASH:</p>
<pre><code>SELECT STANDARD_HASH(123, 'SHA256') FROM DUAL;
# A0740C0829EC3314E5318E1F060266479AA31F8BBBC1868DA42B9E608F52A09F
</code></pre>
<p>Result in Python when a string is passed in:</p>
<pre><code>import hashlib
hashlib.sha256(str.encode(str(123))).hexdigest().upper()
# A665A45920422F9D417E4867EFDC4FB8A04A1F3FFF1FA07E998E86F7F7A27AE3
# I want to modify this function to get the hash value above.
</code></pre>
<p>Maybe this information will also help. I cannot change anything on the Oracle side, but if I could, I would convert the column to <code>CHAR</code> and it would give the same value as my current Python implementation. An example follows.</p>
<p>Result in Oracle when a string passed to STANDARD_HASH:</p>

<p>I've made several attempts, like simply passing in an integer to Python, but this results in the error that a string is required. I've also searched for a way to encode the integer, but haven't made any progress.</p>

Pattern Matching for Country codes in JAVA : <p>I have a requirement to filter out data based on the country codes . For example if the phone numbers are
+911234567891,+922234567891,+933234567893.
Now we need to dynamically create patterns to get the country codes for the phone numbers. Some country codes might be +91,+3581,+93 etc.</p>
<p>can you please suggest an approach</p>

How do you tell pylint what the members of a protobuf-generated object are? : <p>I would like to release a python package for a set of protobuf messages. The protobuf compiler (<code>protoc</code>) generates a python library that does not actually define types/classes the typical sense, but rather dynamically constructs them. Is there any way to hint to pylint what the members and fields of these classes are?</p>
<p>For example, consider the following simple protobuf message specification:</p>
<pre><code>message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3;
}
</code></pre>
<p>The compiler generates the following long pile of code:</p>
