Django debug display all variables of a page

Question

Is there a template tag (or any other trick) I can use to display all the variables available in a page?

Solution 1

If DEBUG is enabled, there's a template tag called {% debug %}

Solution 2

There are several options (some of them already listed before):

1. django builtin debug tag - I use this boilerplate to display it properly:

   <pre> {% filter force_escape %} {% debug %} {% endfilter %} </pre>

2. Use django template debug application's tags like attributes, variables and details or you can even set a breakpoint inside of a template where you can inspect everything with pdb debugger (or ipdb)

3. Django debug toolbar - has a template panel for this purpose

Usually all debug features work only when the app is in DEBUG mode.

Solution 3

Pro tip. Use textarea and auto select onclick for easier copy-paste:

<textarea onclick="this.focus();this.select()" style="width: 100%;"> {% filter force_escape %} {% debug %} {% endfilter %}</textarea>

Solution 4

The debug toolbar does all this and much, much more. See the screencast for more. If you literally just want the variables, you could try

assert False, locals()

in your view

Solution 5

A slightly more complex solution with better rewards is to load django-debug-toolbar (documentation here)

There's an option called 'Templates' with another option to 'Toggle context' and you can see all the variables passed to your template, as well as the ability to see the code behind the template.

Thnaks. As I'm using a generic view, is there a way to summon a "assert False, locals()"

guys, I've debug toolbar installed and working but it doesn't display all the variables available to me in the template... am i missing something.. where does this assert false, locals() go and what exactly does it do?

If you've written a custom view, just put it near the end of your view. If you're using a generic view, you'd need to wrap it in your own view. I think that would work, anyway.

I am getting '<<triggers database query>>' as the value

I would read the documentation and if that fails, I would go to the django-debug-toolbar project and request help: github.com/jazzband/django-debug-toolbar
