I am working on an app that requires changing a flask template to that of Django.How to change the url_for('function') in the html page

In Django you can use:

{% url 'some-url-name' %}

You can also add params as follows:

{% url 'some-url-name' param1=val1 param2=val2 %}

With some-url-name is the name that you give to the url associated with your view like the following:

url(r'^some-url/', 'myapp.views.some_view', name='some-url-name')

If you want to use url namespaces, an example looks like this (we suppose some-url-name is the url name in myapp/urls.py):

url(r'^some-url/', include('myapp.urls', namespace='myapp'))

In your template:

{% url 'myapp:some-url-name' param1=val1 param2=val2 %}

Some differences with static files:

In Flask:

url_for('static', filename='path/to/file')

In Django:

{% static "path/to/file" %}
