This provides basic [Tenjin](http://www.kuwata-lab.com/tenjin/) integration, using a decorator. Tenjin is a blazingly fast templating system, the fastest pure-python system available. For usage and configuration, see the example in the code. I modeled this after Robert Thomson's code for Mako integration.
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 tag is designed to facilitate pagination in the case where both the page number and other parameters (eg. search criteria) are passed via GET. It takes one argument - a dictionary of GET variables to be added to the current url Example usage: {% for page_num in results.paginator.page_range %} <a href="{% append_to_get p=page_num %}">{{ page_num }}</a> {% endfor %} Note that the passed arguments are evaluated within the template context.
You can specyfy max width and height which image can have, and it never exceed that size.
This is a quite simple snippet to integrate postgresql trgm search in django 1.6.10 This snippet is easy to adapt to other special operators by changing the trgm_search function. This example uses the operator `%%` but you could use `ts_vector(fieldname) @@ to_tsquery(%s)`
Active class for navigation link {% navclass default current url %} First argument is the default class and second is the current class Third argument is the url name(s) of the page example: <a class="{% navclass leftnav curentnav name1,name2 %}" href="/about/">
Instead of the default Django User the Auth Model is 'customer' from the usercp App. User's can use username as a display to the public, without disclosing their login information. This way they can use a forum with their username, which is seen by everyone. The login credentials, however are more privat, since it is the e-mail address. Allowing the user to not disclose any information.
The recipe uses deferred constraint validation to create circular references across database tables. The example requires Postgres (MySQL doesn't support deferred constraints). To achieve this, the following is required: * Insertions must be performed in a transaction. Foreign key constraints will be validated at the end of the transactions, allowing for insertion of rows with FKs pointing to rows that don't exist yet. * Primary keys need to be generated before insertion. That's what `prefetch_id` does by pulling the next value from the `*_id_seq` sequence.
You can test how your django app behaves depending on what kind of response it gets from the API. It assumes were're using the python requests library.
A filter to resize a ImageField on demand, a use case could be: <img src="{{ object.image.url }}" alt="original image"> <img src="{{ object.image|thumbnail }}" alt="image resized to default 104x104 format"> <img src="{{ object.image|thumbnail:200x300 }}" alt="image resized to 200x300"> Original http://www.djangosnippets.org/snippets/192/
How I assert email is being sent correctly
Adds init and changes passed args to *args and **kwargs .
Shows the timesince to the user and then on mouseover it will display the exact time for allowing the user to see the exact time. Example: shows "about 1 day, 3 hours ago" and then changes on mouseover to read "at 3:05pm on Wednesday 22nd April 2009"
If your application server is behind a proxy, `request.META["REMOTE_ADDR"]` will likely return the proxy server's IP, not the client's IP. The proxy server will usually provide the client's IP in the `HTTP_X_FORWARDED_FOR` header. This util function checks both headers. I use it behind Amazon's Elastic Load Balancer (ELB).
Mixin to support pagination when randomizing querysets. Requirements: Postgres, Django Sessions Note: This shouldn't be used on large complex datasets. It utilizes the relatively slow method of '?' randomized sorting. Use with caution. Todo: MySQL support, Support for larger datasets
