A collection of tools to make your django life easier.

pip install handy==0.7



A collection of different tools, shortcuts, decorators, form and model fields to make your django life easier.


pip install handy


Here are quick overview of what you can do with handy. You can also read full docs.

Avoid HttpResponse and render_to_response() biolerplate with @render_to() decorator. This one will render result dict to 'app_name/foo.html':

def foo(request):
    return {
        'bar': Bar.objects.all()
        # You can easily override default template, content type,
        # status code and add cookies to response:
        'STATUS': 410,
        'CONTENT_TYPE': 'text/plain'

Easy JSON responders with @render_to_json() decorator:

def posts_by_tag(request, tag=None):
    posts = Post.object.values().filter(tag=tag)
    return list(posts)

And higher order @ajax decorator to handle more complex asynchronous actions:

def enable_post(request):
    post = Post.objects.get(pk=request.GET['id'])

    if post.author != request.user:
        raise ajax.error('permission_denied')

    post.enabled = True

Send emails rendered from templates:

render_to_email(article.author.email, 'approved.html', {'article': article})

A collection of model fields with accompanying form fields and widgets. Most notably different array fields to store array of values or choices:

DAYS = zip(range(7), 'Sun Mon Tue Wed Thu Fri Sat'.split())

class Company(models.Model):
    phones = StringArrayField('Phone numbers', blank=True, default=lambda: [])
    workdays = IntegerArrayField('Work days', choices=DAYS)

company = Company(phones=['234-5016', '516-2314'], workdays=[1,2,3,4])

In model form phones field would be represented as CommaSeparatedInput and workdays as multiple checkboxes:

class CompanyForm(forms.ModelForm):
    class Meta:
        model = Company

A handy @cached_property utility:

class UserProfile(models.Model):
    phones = models.ManyToManyField(Phone)


    def public_phones(self):
        # this queryset will be constructed only once, thanks to @cached_property
        return self.phones.filter(public=True)

A bunch of database querying utilities to not tinker with cursor() anymore:

best_offer = fetch_val('select max(value) from offers where ...')

for row in fetch_named('select * from blog_post'):
    print row.id, row.title

And a middleware to make your html output slimmer by stripping out unnecessary spaces:


And more:

  • simple logger wrap up
  • CommaSeparatedInput and MultilineInput widgets for array fields
  • JSONField, AdditionalAutoField and BigAutoField
  • and a bunch of database, email, text and debugging utilities

NOTE: functional tools, namely @memoize and @cache, moved to funcy
