Closed 3 years ago.

What is the right way to write something like this in jinja2 :

{% for items in zipped %}
<img src="{{ url_for('static', filename='img/{{items.logo}}') }}" />

Notice that items.logo is within another variable .

回答1:

items.logo is already a variable. Try:

{% for items in zipped %}
    <img src="{{ url_for('static', filename='img/' + items.logo) }}" />
{% endfor %}
