An "if-style" template tag that checks to see if a user belongs to a one or mores groups (by name). Usage: `{% ifusergroup Admins %} ... {% endifusergroup %} or {% ifusergroup Admins Clients Programmers Managers %} ... {% else %} ... {% endifusergroup %}`
A simple 2-tuple list of time zones for use in a choice field or select box for Django, or wherever needed.
This feed class outputs an existing xml feed as json
I had to build unique strings for a payment system and i wanted to make them kindof friendly so i generated them with usernames and datetimes(safe enough uniqueness in combo), some usernames are long and they break the limit of this payment system so i thought i should cut the center of the string so it stills has a part of the username and a part of the datetime, the most changing part of the datetime is of course the last part, as microseconds vary rapidly. So i wrote this little function to cut the center of a string i thought it cute so i leave it here. Pay attention to the comment so you can see what is going on.
1. Create an app and place this in `admin.py`. 2. Add `url(r'^login/$', 'social_auth.views.auth', {'backend': 'google'}, name='login')` to your `urls.py`. 3. Add the app to your `INSTALLED_APPS` after `django.contrib.admin`. 4. Set `USE_SOCIAL_AUTH_AS_ADMIN_LOGIN = True` in your `settings.py`. 5. ... 6. Profit.
I had a hell of a time getting most QR code stuffs out there working with Django. Many projects, but problems here and problems there. The only additional code you'll need for this is to "pip install qrcode". After that, you're free to <img src="{% qrcode_datauri "http://localhost:8000/" %}" />.
[See blog post](http://paltman.com/2008/04/11/keeping-contenttypes-and-permissions-updated-without-syncdb/) You can put this script in the root of your project and run after deploying updates in your production environment.
Example usage: Add static var with static value to get : {% urlget 'var'='val' %} Add dynamic val (from template vars) to static variable: {% urlget 'var'=val %} Using dynamic variable names works similiar - adding dynamic varialbe (from template vars) : {% urlget var='val' %} Clearing variable from GET string : {% urlget 'var'='' %} Retrieving GET string: {% urlget %}
Use this class to partially update one or more fields of a model. Only the fields that are bound to the form via the "data" parameter in the constructor get updated. All automatically generated fields have their "required" attribute set to False. Example 1: from django.contrib.auth.models import User class PatchUserForm(PatchModelForm): class Meta: model = User user = User.objects.get(username='old_username') form = PatchUserForm(data={'username':'new_username'}, instance=user) form.is_valid() form.save() Example 2: from django.contrib.auth.models import User class PatchUserForm(PatchModelForm): class Meta: model = User user = User.objects.get(pk=35) form = PatchUserForm(data={'last_name':'Smith', 'is_staff': True}, instance=user) form.is_valid() form.save()
Adding this mixing to your existing class based views allows for outputting of queries into any registered serialzier format -- very handy for dynamic JS based GUI on the JSON format. This generic view mixing was created on our last project which required a fancy JS based user experience and yet also needed to be accessible through non JS enabled browsers.
Perhaps this is blindingly obvious but I spent a while trying to get this, before figuring out that when a each item of an iterated ValuesQuerySet is a dict. Useful for serialising to JSON or XML etc.
With this function if you filter using regular admin filters you'll reduce the queryset to the objects in view.
Please provide suggestions on refining this code. Thanks.
Place the above code in your view, and then you can use it to specify what template to use. Set elements of the context as a dictionary and that gets passed to the template as well. For example: In view.py: #################################### @with_template('friends/index.html') def friends(request, context, username): context['user'] = User.objects.get(username = username) in friends/index.html: {% extends "base.html" %} {% block content %} <h1>{{ user.username }}'s Friends</h1>
When you need to include a specific javascript file/code snippet in your page, it's always better to do it at the bottom of your page to avoid to block the rendering too soon. This tag provide you a nice way to include and launch only what is needed: Example in an included template that need to display google maps: {% dict js_file google_api %} <script src="http://www.google.com/jsapi?key={{ MAPS_API_KEY }}" type="text/javascript" charset="utf-8"></script> <script src="{{MEDIA_URL}}js/map.display.js" type="text/javascript">...</script> {% enddict %} {% dict js_code link_map %} $('.show-map').click(function() { ... }); $('.hide-map').click(function() { ... }); {% enddict %} Finaly you just have to add this to the very bottom of your base.html file: .... </body> {% for k,v in js_file.items %} {{v}} {% endfor %} <script type="text/javascript"> /* <![CDATA[ */ {% for k,v in js_code.items %} {{v}} {% endfor %} /* ]]> */ </script> </html>
