Invalid template syntax in django_comments/templates/comments/preview.html

[maurizi]

Posting a comment that causes a validation error, such as a comment longer than 300 characters, is supposed to show the django_comments/templates/comments/preview.html template.

From my testing however, I always get an unhandled error from this line.

TemplateSyntaxError at /comments/post/
Invalid block tag: 'comment_form_target', expected 'endblock'

I am using Django 1.8 and Python 2.7

Weird, because the template is tested. You might try to debug at the point of failure in the traceback to see if this is caused by another problem.

Here's the full trace:

It's odd, the preview.html template seems to load the comments template tags.

I didn't know {% load %} tags could be used this way, I always assumed they had to be placed at the top of the file.

[claudep]

@maurizi Could you try changing the location of the load tag to see if this makes any difference?

[maurizi]

I moved the {% load comments %} up to the top of the page, but it didn't seem to fix the problem.
