How to See if a String Contains Another String in Django Template

Question

This is my code in a template.

{% if 'index.html' in  "{{ request.build_absolute_uri  }}" %}      'hello' {% else %}           'bye' {% endif %} 

Now my url value currently is "http://127.0.0.1:8000/login?next=/index.html"

Even though "index.html" is there in the string it still prints bye.

When I run the same code in a python shell it works. Not sure what the mistake is.

Try removing the extra {{...}} tags and the "..." quotes around request.build_absolute_uri, it worked for me.

Since you are already within an {% if %} tag, there is no need to surround request.build_absolute_uri with {{...}} tags.

{% if 'index.html' in request.build_absolute_uri %}     hello {% else %}     bye {% endif %} 

Because of the quotes you are literally searching the string "{{ request.build_absolute_uri }}" and not the evaluated Django tag you intended.
