django-fastdev

==============

:code:`django-fastdev` is an app that makes it safer, faster and more fun to develop Django apps.

Features

--------

Error on non-existent template variables

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Django templates by default hide errors, and when it does show an error it's often not very helpful. This app will change this so that if you do:

.. code:: html

    {{ does_not_exist }}

instead of rendering that as an empty string, this app will give you an error message:

.. code::

    does_not_exist does not exist in context. Available top level variables:

        DEFAULT_MESSAGE_LEVELS

        False

        None

        True

        bar

        csrf_token

        foo

        messages

        perms

        request

        user

There are more specialized error messages for when you try to access the contents of a :code:`dict`, and attributes of an object a few levels deep like :code:`foo.bar.baz` (where baz doesn't exist).

By default, :code:`django-fastdev` only checks templates that exist within your project directory. If you want it to check ALL templates, including stock django templates and templates from third party libraries, add :code:`FASTDEV_STRICT_TEMPLATE_CHECKING = True` to your project :code:`settings.py`.

Improved TemplateDoesNotExist errors

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Good suggestions for what you wanted to do, and a complete list of all valid values makes it very easy to fix `TemplateDoesNotExist` errors.

NoReverseMatch errors

~~~~~~~~~~~~~~~~~~~~~

Have you ever gotten this error?

.. code::

    django.urls.exceptions.NoReverseMatch: Reverse for 'view-name' with arguments '('',)' not found. 1 pattern(s) tried:

It's because you have :code:`{% url 'view-name' does_not_exist %}`. Django sees

:code:`does_not_exist` and evaluates it to the empty string because it doesn't exist.

So that's why you get an error message that makes no sense. :code:`django-fastdev` will

make your code crash on the actual error: :code:`does_not_exist` doesn't exist.

Error if you have non-space text outside a block when extending

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A common mistake for beginners that can be hard to spot is when they do:

..  code-block:: html

    

        {% extends "something.html" %}

        stuff here

    

Django silently throws away :code:`stuff here` and :code:`

            {% block content %}{% endblock %}
