Django - tag inside template tag

Question

Therefore, I use the django-jcrop to crop the image. Inside my HTML file, I have this line:

 <img src="{% cropped_thumbnail order 'cropping' max_size='{{ ratio }}' %}"> 

When this is transmitted, I get the following error:

 TemplateSyntaxError: max_size must match INTxINT 

{{ ratio }} is passed correctly outside the tag and gives the correct 400x400 value. When I remove single quotes from max_size='{{ ratio }}' , I get the following error:

 TemplateSyntaxError: Could not parse the remainder: '{{' from '{{' 

Thus, I am sure that the relation is not parsed correctly in the tag. Any ideas why?

Answer 1

inside the template tag you do not need to use "{{}}", you can try the following code:

 <img src="{% cropped_thumbnail order 'cropping' max_size=ratio %}">
