Iterate over the same list twice in Jinja2?
google-app-engine, jinja2, python
Solution
If `tags` is an iterator, then at the end of the first iteration, there won't be anything left to iterate. You could materialise it to a list before passing it to your template `eg: list(tags)` in your context...
Problem
I'm trying to print a list of tags in two separate places, but the second time I for/in the list, it doesn't loop. ``` <ul> # for tag in tags <li><a href="/my-tags/{{tag.name}}">{{tag.name}}</a></li> # endfor </ul> <ul> # for tag in tags <li><a href="/my-tags/{{tag.name}}">{{tag.name}}</a></li> # endfor </ul> ``` The second UL ends up empty if I put that in my template. Any ideas? Edit: This is how I'm populating the tags variable. ``` contact_data.append({'name': 'Placeholder', 'emails': contact.emails, 'tags': [tag for tag in nt_tags.get_tags_by_taggee(contact)]}) ``` Edit againt: Logged what I'm passing and its ``` [<nt_tags.Tag object at 0x0000000005CAFF28>, <nt_tags.Tag object at 0x0000000005CAFFD0>] ``` Which looks like just a list not an iterator right?
