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)`
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.
PreviewMixin adds a preview page for Django's CBV (FormView, UpdateView, CreateView). After a form has been submitted, it is returned again, optionally in a different template to confirm. If the form is submitted with the same data, the default "form_valid" function is executed. Features: 1. `process_preview` - function executed after submitting the form for the first time (default is to do nothing) 2. `done` - function for the action if the confirm page is sent (defaults to whatever form_valid of the django cbv does) 3. `preview_template_name` - variable with the name of the template for the confirm page (defaults to taking the same template as for the initial form) 4. new function `security_hash` to calculate a hash which is added to the confirmation form. Works kind of like django-formtools, just as a Mixin for the default Django cbv.
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 use this as a model method.
Adds init and changes passed args to *args and **kwargs .
This snippets extends ModelAdmin in order to allow multi field sorting in admin tables. Usage example: class MyModelAdmin(MultiFieldSortableModelAdmin): list_display = ( ... 'user_full_name', ... ) def user_full_name(self, obj): return obj.user.get_full_name() user_full_name.admin_order_field = ['user__first_name', 'user__last_name']`
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.
This snippet holds your Django project from automatically changing language of the page to the best fitting one by discovering the client browser language. I personally needed to show the page to the user for the first time in the default language (English), although there were some translations. User can still change the language (via session cookies). Insert this middleware BEFORE the Django's `django.middleware.locale.LocaleMiddleware` in settings.
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
I am used to load forms directly into modals using dajax but I found out I had to load the scripts using an ajax call from the browser. You can see here an example of a dynamically loaded form and the function used to load the scripts.
