Log Django exceptions to file. Contains snippet for both WatchedFileHandler and RotatingFileHandler handlers. Configurations mentioned are separate And only works if the DEBUG = False. Use "python manage.py runserver --no-reload" If you get file in use error.
Custom form widget for rendering an autocomplete (using jQuery UI's autocomplete widget) text input in a template. This arose from the need to have all fields asking for a state to use autocomplete, so I decided to make this.
This middleware will add a log of the SQL queries executed at the bottom of every page. It also includes a query count and total and per-query execution times.
Does exactly what it says on the tin! This template tag, when implemented, converts a duration (in seconds) to a more meaningful format. It has a short and long setting, which is easy to manipulate for your needs. Apologies if something already exists like this, however I felt that writing this would be quicker than trying to find it online. As an example, given the duration 84658: Short (default): 23 hrs 30 mins 58 secs Long: 23 hours, 30 minutes and 58 seconds All the best, [Dan Ward](http://d-w.me).
This is a template tag that works like `{% include %}`, but instead of loading a template from a file, it uses some text from the current context, and renders that as though it were itself a template. This means, amongst other things, that you can use template tags and filters in database fields. For example, instead of: `{{ flatpage.content }}` you could use: `{% render_as_template flatpage.content %}` Then you can use template tags (such as `{% url showprofile user.id %}`) in flat pages, stored in the database. The template is rendered with the current context. Warning - only allow trusted users to edit content that gets rendered with this tag.
This is an extract of an example for use of "pisa" <http://www.htmltopdf.org> in "django". It shows the easiest way possible to create PDF documents just using HTML and CSS. In "index" we see the definition of the output of a form in which HTML code can be typed in and then on the fly a PDF will be created. In "ezpdf_sample" we see the use of templates and contexts. So adding PDF to your existing Django project could be just a matter of some lines of code.
Includes the Javascript for Google Analytics. Will not show Google Analytics code when DEBUG is on or to staff users. Use {% googleanalyticsjs %} in your templates. You must set something like GOOGLE_ANALYTICS_CODE = "UA-1234567-1" in your settings file. Assumes 'user' in your template variables is request.user, which it will be if you use: return render_to_response('template.html',{ }, context_instance=RequestContext(request)) (Assuming django.core.context_processors.auth is in TEMPLATE_CONTEXT_PROCESSORS, which it is by default)

The simplest way of displaying a "details" table about any model, is to show a ModelFrom with all fields readonly or (selects) disabled. Also, the labels are preferably translatable, not just capitalized names of the column tables in your models. So the constructor translates the field labels as well.
This snippet shows how to add additional parameters to the queryset of a ModelChoiceField, enabling you to for instance filter the query.
This is a little snippet that you can use to make your Django newforms dynamic at runtime. You can define an arbitrary number of fields of the form without loosing newforms capibilites. You can render the form dynamically be "misusing" the "help_text" attribute of the form fields (Every form field allows the definition of this attribute). This way you can search for changes in the help_text of every field and render the form accordingly. The form itself is dynamically defined in the view. The form state can be saved in a Django Session Variable (specifically for Linux users with a process-based Apache Server), so that you can rebuild and verify a submitted form.
** Allows to get field value in the template. ** First load template tag. Then {% field_value form.field %}
The result maybe: http://localhost/test/ And for request.path, it will not include the domain field(http://localhost).
If you want to test for trivial error in your add and changelist admin views, use this snippet. Save the snippet in admintests.py and put it anywhere in your pythonpath. Put this code in your tests.py: from django.test import TestCase from admintest import adminviews_test class TestAdminViews(TestCase): def test_admin_views(self): adminviews_test(self)
This works with `Django 1.0.0` and later. It sets the `request.urlconf` variable to an alternate urlconf, if there's a match to the hostname in `settings.MULTIHOST_URLCONF_MAP`
