URL reversion in Django template when pattern name is variable

Question

I am passing a variable in django template named "link". This is my code snippet in views.py

 link = "msdetail/{{item.post_id}}"
 return render(request, "mart/all-products.html", {'t': ms, 'cat':category, 'link':link})

and on html file :

<a href={% url '{{link}}' %} class="btn btn-primary">View</a>

it is giving this error:

"NoReverseMatch at /mart/menshirt Reverse for '{{link}}' not found. '{{link}}' is not a valid view function or pattern name.".....

the error happens when i click the button. Can I not pass url like this or is it some other issue?

Answer 1

Solution

<a href='{{link}}' class="btn btn-primary">View</a>

Why is that?

Typing {% url 'X' %} is saying, Get me the URL which has name='X' .

This is not the case, Your case has a variable that you want to include it in the context, That's all.
