superSearch is intended to make it easier to make complex OR queries, thusly hitting the database less. EXAMPLE: Searching for a user named 'Eric Neuman' would be difficult because first_name and last_name are separate fields. However, with superSearch, it's a breeze. query = ['Eric Neuman'] f = ['first_name','last_name'] s = query.split(' ') m = ['icontains'] results = superSearch(User, f, m,s)
A simple Django form field which validates a list of emails. [See this at my blog](http://sciyoshi.com/blog/2009/aug/08/emaillistfield-django/)
This Base64Field class can be used as an alternative to a BlobField, which is not supported by Django out of the box. The base64 encoded data can be accessed by appending _base64 to the field name. This is especially handy when using this field for sending eMails with attachment which need to be base64 encoded anyways. **Example use:** class Foo(models.Model): data = Base64Field() foo = Foo() foo.data = 'Hello world!' print foo.data # will 'Hello world!' print foo.data_base64 # will print 'SGVsbG8gd29ybGQh\n'
Although many people have already posted cookieless session middlewares and related stuffs, but this one is just for only required views. You can use this as a view decorator like: @session_from_http_params @login_required def your_view(request): ... This is very useful for those who use SWFUpload. Flash has a bug with sending cookies properly, so SWFUpload offers an workaround -- session key as a POST parameter.
We currently use two-level tuples to specify choices of a field in models or forms. But, because it has only (value, verbose name) pair, the readability is bad whenever we indicate a specific choice value in our Python codes. So I made a small class that does "magic" for this: A Named Enumeration. Instead of `myobj.status == 0`, use `myobj.status == STATUS.UNREVIEWED`, for example.
This is a rewrite of [snippet #1006](http://www.djangosnippets.org/snippets/1006/) to use the moderation features available in Django's comments framework. This is more customizable than the signals approach and works well if other moderation features are being used. If you want to make comments that are flagged as spam become hidden instead of deleted, change the allow() method to moderate(). [See the blog post here](http://sciyoshi.com/blog/2009/jul/17/prevent-django-newcomments-spam-akismet-reloaded/)
A confirm alert is displayed if the user has made any changes to the form, and attempts to navigate away from the page without saving (click the back button, hit reload, click the breadcrumbs, logout, etc). Much like GMail's "Your message has not been sent. Discard your message?" prompt. **Uses the JavaScript helpers built into Django**, without relying on 3rd party libs like jQuery. (There might be simpler options if you're already using [jQuery](http://code.google.com/p/protect-data/) or [prototype](http://stackoverflow.com/questions/925111/activating-onbeforeunload-only-when-field-values-have-changed/1013033#1013033)). To use this, simply create a [custom admin template](http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-admin-templates). For example at: *templates/admin/YOUR_APP_NAME/change_form.html* {% extends "admin/change_form.html" %} {% block after_related_objects %} {{ block.super}} <script type="text/javascript"> ... script goes here ... </script> {% endblock %}
The widget for FileField and ImageField has a problem: it doesn't supports clear its value and it doesn't delete the old file when you replace it for a new one. This is a solution for this. It is just for Admin, but you can make changes to be compatible with common forms. The jQuery code will put an **<input type="checkbox">** tag next to every **<input type="file">** and user can check it to clear the field value. When a user just replace the current file for a new one, the old file will be deleted.
Simple function that tests whether a given IP address is in a list of IP addresses or subnets. Requires `ipaddr`. Comes with Python 2.7 or 3.1, [downloadable here](http://code.google.com/p/ipaddr-py/) for earlier versions. More info on `ipaddr` [in Python 3.1 docs](http://docs.python.org/dev/py3k/library/ipaddr.html).
A template tag which returns the n last tweets of a given user. It uses the twitter python lib. {% get_twitter_messages user foo limit 5 as tweets %} {% for tweet in tweets %} {{ tweet.text }} {{ tweet.time }} {{ tweet.url }} {% endfor %}
[The Django Admin Action documentation leads you through exporting a queryset to JSON](http://docs.djangoproject.com/en/dev/ref/contrib/admin/actions/#actions-that-provide-intermediate-pages). However exporting from a single model rarely tells the whole story. Using the CollectObjects class, `export_related_as_json` gathers all instances related by foreign keys to what is being exported and exports them as well in a serialization bonanza. Use it to export Users and you'll get their Profile objects as well! **Usage** # admin.py from django.contrib import admin admin.site.add_action(export_related_as_json)
Assume you have a model called Delegate and you want to tweet whenever a new Delegate registers, the code above will do this. You need to install python-twitter.
This snippet shows a way to preserve GET arguments with pagination. Many people make mistakes to omit the query arguments besides page arguments for the pagination, and making sure correct may sphagettize your code.
This middleware implements a "soft timeout". This means the admin is sent an email whenever a page time exceeds a certian value. It is intended to run on production servers to inform the admin of any pages which are performing slowly.
This snippet is a variation on snippet 1550 that works with the Eclipse pydev plugin. This allows you to set up a breakpoint anywhere in your template code, by simply writing {% pydev_debug %}. Be sure to launch pydev in debugger mode first. Once you're in the debugger, you can explore the stack and quickly find which context variables are set. This can be especially useful inside for loops, etc., where you want to see how the templating code is mucking with the context. This can also be useful when your templates are ultimately rendered by code that might not understand very well, such as generics.
