TemplateSyntaxError: expected token ':', got '}'

This is my source code:

<ul class="filebase">
        {% for file in finance %}
        <li class="filelist">
            <div class="file-author"><a href="http://127.0.0.1:5000/uploads/files/{{file. filename}}">{{ file.filename }}</a></div>
            <div class="file-body">Description: {{ file.description }}</div>
            <div class="file-date">Date posted: {{ moment(file.date).fromNow() }}</div>
            <div class="delete-file"><a href="{{ url_for('.delete_file', file_name={{ file.filename }} ) }}">Delete File</a></div><br>
        </li>
        {% endfor %}

At first, my code was working, suddenly I got an error like this:

TemplateSyntaxError: expected token ':', got '}'

Here's my Traceback (If you need):

Don't do more {{}} inside of other {{}} blocks.

Here's my url_for() call:

<a href="{{ url_for('viewBlog', userid=item.userid)}}"></a>

I was getting that same error when it looked like this:

<a href="{{ url_for('viewBlog', userid={{item.userid}}) }}"></a>

Once I removed the inner {{}}, the problem went away.
