Check for presence of context data that is not provided

Using Django Templates & Frontend
1

. Django converts it to blank if there is no context.

. I want to check if I’m missing any context.

. How to log or raise if there is a missing context

Are you looking for finding untranslated strings in your code automatically?!

Your question is not really clear, but if you’re talking about a variable that doesn’t exist in the context, this can help

you will need to pass data in the context. Can you share the view that is rendering to the template?

I think it did not need template.
Because I’m looking for a way to raise if there’s a missing context, not find template error solution.

Did I explain it wrong?
Or did you misunderstand?
Would you please share your understanding with me so I can edit the text?

It will be easier for others to help if you provide more information about what you want to achieve.
Sharing the related views/templates would help.

The point here, is that normally you’re the one that builds the context, so you could check if you have a missing value.

Frankly the current version of the post is not helping. Please share the View that is rendering the page. Also share the template.

I’m talking about structure, why do you keep talking about views.py and templates??
Could you please explain in detail so I can understand what you are saying??

Well, let’s clear things out here. You’re seeking for help, but you think that the way your ask for help is better than the way we’re trying to help you. This is just making things harder for you to get the help you need.

From what you’re describing, context, django converting to blank text, refers to what does when is processing a view/template. That’s why we are asking for this information to help you achieve what you want.

What I don’t get it is that you already know what you want to achieve, and probably already know the ways to do it.
For example, imagine i have the following view.

def my_view(request):
  context = {"foo": "bar"}
  return render(request, "my_template.html", context=context)

I’m the one who’s creating and handling the context, so I can do whatever I want with it.

def my_view(request):
  context = {"foo": "bar"}
  if not context.get("cez"):
    raise ValueError("Missing key 'cez'")
  return render(request, "my_template.html", context=context)

Obviously, the example above is silly, because this will always raise an error.
But you get the idea.
Now, are you trying to do something like this in one of your views, or some other sort of view that you don’t have control of?
Sharing them would be useful for us to help on that specific case.
