Project description

A set of Django useful utilities.

  • ImageField with preview in admin interface
  • Override allows to create users with dot in username
  • Localized date filter
  • ConsoleException middleware

Installation:

  1. Put utilities in to your INSTALLED_APPS in your settings.py within your django project.

Usage:

ImagePreviewField:

Used to show image preview near ImageField.

To use it in your models.py

from utilities.fields import ImagePreviewFieldd

class MyModel(models.Model):
        image = ImagePreviewField(upload_to='upload/')

You can specify maximum width and height for the thumb

class MyModel(models.Model):
        image = ImagePreviewField(upload_to='upload/', thumb_size=(80, 80))

If you have separated field with thumb for this image you can specify its name and told to use its real size:

class MyModel(models.Model):
        thumb = models.ImageField(upload_to='thumb/')
        image = ImagePreviewField(upload_to='upload/', thumb_field='thumb', thumb_size=None)

Dot is username:

By default this application will allow you to create users in admin with dot in there names. To disallow set ALLOW_DOT_IS_USERNAME to False in your settings.py.

Local date template filter:

The date_local filter supposed to be used with Django 1.1 (1.2+ already has such feature ). Load filter with {% load utilities_tags %} and use it like date Django date filter

For example:

{{ entry.creation_date|date_local:"d F Y" }}

Returns 01 Января 2010 for ru locale

ConsoleException middleware:

Often you get annoyed when Django show Tracebacks like

File "/home/mysite/django-mysite3/django/template/__init__.py", line
800, in render_node
return node.render(context)

ConsoleException middleware prints original tracebacks in STDOUT. It is very helpful for debugging sometimes. Use it ONLY in development mode!

Reset password form:

To enable password reset form, set in your settings.py:

ENABLE_PASSWORD_RESET = True

And include utilities urls into your urlconf:

urlpatterns += patterns('',
    (r'^', include('utilities.urls')),
)

You will get link to password reset in users administration section under email field. When you reset password to some user, all his or her active sessions will be deleted, password will be set to unusable. The only way to login is follow link, provided in email. If user has no email, you will not able reset password for this user.

SplitDateField:

You can specify minimal and maximum date with attributes from_date (default datetime.date(1930,01,01)) and till_date (default datetime.date.today) , they must have date type or be callable object. Also you may reverse order of years with help of boolean attribute reverse (default False).

If from_date=datetime.date(2007,01,01), till_date=datetime.date(2010,01,01) and reverse=False, then we obtain the sequence of years: 2007, 2008, 2009, 2010

To use it in your models.py

from utilities.fields import SplitDateField

  class MyModel(models.Model):
    date = SplitDateField(from_date=datetime.date(2008,10,01),
      till_date=datetime.date.today, reverse=True)

To use it in your forms.py

from utilities.fields import SplitDateFormField

  class MyForm(forms.Form)
    date = SplitDateFormField(from_date=datetime.date(2008,10,01),
      till_date=datetime.date.today, reverse=True)

Management commands:

Since 0.1.4 few management commands added:

imagekit_recache
Re-create cache for imagekit models. Command has –force option to delete old cache dir.
update_permissions
Update permissions for installed models. Useful if you change permissions in project’s lifecycle.

AJAX CRSF:

Django CSRF protection (https://docs.djangoproject.com/en/dev/ref/contrib/csrf/#ajax) documentation

offer solution to set CSRF headers to ajax requests on site. That solution copied into utulities script to avoid copy-paste.:

<script type="text/javascript" src="{{ STATIC_URL }}utilities/js/csrf.js" />
