Django-quicky

A collection of tools to make setting up Django quicker.

You will love this tool if you ever wished you could do:

@url('/user/\d+')
@view(render_to='user.html'):
def user_view(request, id)
    ...
    return {'users': users}


@user_view.ajax(render_to='json')
def ajax_user_view(request, id, context):
    ...
    return context

Note that this software is beta, but it's already used in production.

Just pip install django-quicky.

Url decorators

If you like micro frameworks like bottle, you probably miss the very easy way to declare a route.

Now you can do this:

from django_quicky import routing

url, urlpatterns = routing()


@url('/any/regex/django/accepts')
def an_ordinary_view(request):
    ...


@url('/you/can/stack/routing')
@url('/any/regex/django/accepts')
def an_ordinary_view(request):
    ...

Just declare your routes in the view. And use your view file in URL_ROOT or any include() like you would do with urls.py.

Remember, order matters, so:

• views declared first will match first. Avoid declaring @url(r'^$') first (at the begining of views.py) or it will prevent others from matching.
• when using several @url on the same view, the first applied (the lowest @url in the decorators pile) will match first.
• always put @url as the LAST decorator applied (at the very top of the decorators pile).

If you are in the mood for fancy stuff, and feel like adding a url manually, just do:

urlpatterns.add_url(url, view, [kwargs, name, prefix])

And for an include:

urlpatterns.include(url, view, [name, prefix])

And since you often add the admin url:

urlpatterns.add_admin(url)

Adding http error views is neither hard nor useful (most of the time), but for completeness:

@url.http404
def http404(request):
    ...

Of course, your view needs to return the proper status code.

View decorators

Rendering template and json bore you to death?

from django_quicky import view

@view(render_to='template.html')
def an_ordinary_view(request):
    return {'stuff': stuff}


@view(render_to='json')
def an_json_view(request):
    return {'stuff': stuff}

@view(render_to='raw')
def an_json_view(request):
    return 'hey'

For the first one, the returned dictionary will be used as a context (with RequestContext) to render the template. For the second one, it will be serialised to JSON. The last one will just return the string.

/!\ WARNING:

The view decorator should always be the first decorator to be applied (the lowest one in the decorator pile).

Conditional rendering

You can also declare alternatives based on a condition, for a single view:

from django_quicky import view

@view(render_to='template.html')
def common_views(request):
    return {'stuff': stuff}

@common_views.post()
def post_view(request, context):
    # do more stuff
    return context

@common_views.ajax(render_to='json')
def json_view(request, context):
    return context

The first view will be rendered as-is if it receives a normal GET request. The second view will be rendered only for POST requests, but will be passed the result of the execution of the first view. The second view will be rendered only for AJAX requests, and as JSON, but will be passed the result of the execution first view.

Just remember that alternative views must accept context as a parameter, because they will always receive the result of the main view.

Oh, and of course you can define your own conditions:

@view(render_to='template.html')
def common_views(request):
    return {'stuff': stuff}

@common_views.render_if(conditon=a_function_that_returns_a_bool)
def conditional_view(request, context):
    # do more stuff
    return context

Super user middleware

Double authentification? Short session timeout? Permission issue? Loooooooong password.

In, dev, just do:

if DEBUG:

    MIDDLEWARE_CLASSES += (
        'django_quicky.middleware.ForceSuperUserMiddleWare',
    )

You will always be logged in as a super user. No password required. No timeout.

Serve static middleware

Serving static files IN DEV without worries:

if DEBUG:

    MIDDLEWARE_CLASSES += (
        'django_quicky.middleware.StaticServe',
    )

And if you do want to test your site with DEBUG set to False, you can just remove the condition.

(Idea borrowed from the excellent django-annoying, but I stripped the internal test on DEBUG which is a pain during testing.)

Settings context processor

Because everyone ends up needing access to the settings in his templates one day or the other:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    "django_quicky.context_processors.settings"
)

DEBUGGING

The first rule when debugging decorators, is to be sure you use the right syntax: @decorator and @decorator() are very different and both syntaxically valid. In django-quickly's case, all decorators should be called with @decorator() or @decorator(arguments).

Also remember that when it comes to decorators, order matters. Most of the time, you don't care about the order you apply your decorators, but in this case, you should ALWAYS apply @view first and @url last. E.G:

@url(r'$')
@login_required
@view('app/home.html')
def home(request):
    ...

If you don't do this, some decorators will never be executed as @view bypasses decorators applied before it and @url bypasses decorators after it.

Also, the order in which you declare your fonction matters, just like patterns order matters in urls.py. So avoid putting global matching urls such as @url('^$') at the begining of views.py, otherwise this view will be used all the time, since the others will never have a chance to match.

Last words

There are other utility functions, but I didn't take the time to document them here, so you'll have to dig in the code. fields.py contains some useful model fields, utils.py has some shortcut functions and models.py comes with tools to get random entries or patch a model.
