Django slugified urls - how to handle collisions? | 2,340,063 | 0 | 7 | 3,203 | 0 | python,django,url,slug,collision | I would (in the form validation) just check to see if the slug is used, and then add something to it, either a number "my-cool-idea_2" or the actual id | 0 | 0 | 0 | 0 | 2009-09-29T04:23:00.000 | 4 | 0 | false | 1,490,559 | 0 | 0 | 1 | 2 | I'm currently working on a toy project in Django.
Part of my app allows users to leave reviews. I'd like to take the title of the review and slugify it to create a url.
So, if a user writes a review called "The best thing ever!", the url would be something like: www.example.com/reviews/the-best-thing-ever.

Separate Admin/User authentication system in Django | 1,494,572 | 0 | 8 | 3,543 | 0 | python,django,authentication | Modify things slightly so that users have a category prefix on their username? You haven't given us much info on what you want to do, it's possible that your needs might be met by using the sites framework, or simply two separate django installs.

Rather than create a whole new auth system, I'd like to leverage django's built-in functionality (i.e. session management, @login_required decorator, etc.).

Aggregating multiple feeds with Universal Feed Parser | 1,496,616 | 1 | 0 | 1,280 | 0 | python,django | Here is already suggestion to store data in the database, e.g. bsddb.btopen() or any RDBMS.
Take a look at heapq.merge() and bisect.insort() or use one of B-tree implementations if you'd like to merge data in memory. | 0 | 0 | 1 | 0 | 2009-09-30T04:04:00.000 | 2 | 0.099668 | false | 1,496,067 | 0 | 0 | 1 | 1 | Having great luck working with single-source feed parsing in Universal Feed Parser, but now I need to run multiple feeds through it and generate chronologically interleaved output (not RSS).

Run a task every hour on the hour with App Engine's cron API | 1,501,925 | -1 | 4 | 3,297 | 0 | python,google-app-engine,cron | Looking over the docs, I agree that your 24 cron entry idea is the only documented way that would work.

Run a task every hour on the hour with App Engine's cron API | 1,501,960 | 1 | 4 | 3,297 | 0 | python,google-app-engine,cron | The docs say you can have 20 cron entries, so you can't have one for every hour of the day.
You could run your task every minute and check if it is the first minute of the hour - exit otherwise. | 0 | 1 | 0 | 0 | 2009-10-01T04:36:00.000 | 4 | 0.049958 | false | 1,501,907 | 0 | 0 | 1 | 2 | I need to run a task every hour on the hour (00:00, 01:00, 02:00, ..., 23:00) every day of the week, but can't seem to find an example in App Engine's docs of how to do this.

Using IronPython to learn the .NET framework, is this bad? | 1,551,802 | 5 | 4 | 477 | 0 | c#,.net,ironpython | If I wanted to just "learn the framework", I would do it in C# or VB for two main reasons:
Intellisense - the framework is huge, and being offered suggestions for function overloads is one of the ways to find new stuff.

Using IronPython to learn the .NET framework, is this bad? | 1,504,823 | 11 | 4 | 477 | 0 | c#,.net,ironpython | No, sounds like a good way to learn to me. You get to stick with a language and syntax that you are familiar with, and learn about the huge range of classes available in the framework, and how the CLR supports your code.
Once you've got to grips with some of the framework and the CLR services you could always pick up C... | 0 | 0 | 0 | 1 | 2009-10-01T15:55:00.000 | 4 | 1.2 | true | 1,504,804 | 1 | 0 | 1 | 3 | Because I'm a Python fan, I'd like to learn the .NET framework using IronPython.
