TaskViewMixin can be mixed in with a Class Based view and handles the scheduling and polling of a task. During task execution, a waiting page is rendered that should refresh itself. Once the task is complete, the view may then render a success page and can collect the payload of the task for rendering the result.
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>
