2,590 PointsError when looping through dictionaries
Whenever I am trying to loop through dictionaries in my html document, I am getting an error:
jinja2.exceptions.TemplateSyntaxError: expected token ':', got '}'
with a code like this:
{% for i in {{Database.items()}} %}
<p>ID {{i[0]}}</p>
{% for j in i[1] %}
<p>{{j}}</p>
{% endfor %}
{% endfor %}
In this this case, the keys of the dictionary are strings and the values are lists. What daoes this error mean and how do i fix it?

44,806 PointsBetween {% and %}, you can use variables without surrounding them with {{ and }}. Try changing {% for i in {{Database.items()}} %} to {% for i in Database.items() %}
