Can we use python related api's on the Django templates ?

[ratnadeep ray]

Hi all, 

Currently I am trying to print the type of a variable from the Django template html file as follows: 

    <center><h2>The type of feature list report for version {%type(version)%} is<h2></center>

For the above, I am getting the following error: 

Invalid block tag on line 9: 'type(version)'. Did you forget to register or load this tag?

So what's going wrong here? How can we use the python related api's (like type) from the html template files? I think inside the {% .... %} we can use python related evaluations. Am I right? 

Please throw some lights on this .

Thanks.

No, you are wrong, and this is explicitly pointed out in the docs (https://docs.djangoproject.com/en/3.0/ref/templates/language/):

> bear in mind that the Django template system is not simply Python embedded into HTML. This is by design: the template system is meant to express presentation, not program logic.

While you cannot use Python operators and functions directly in the templates, you can write your own "wrappers" around those you need:
