Pass Dynamic Value to Django url built-in

Question

Within a view, I am maintaining a dictionary containing some data I would like to display in an <a> in a template with the Django url built-in.

my_view.py

links = [
  {
    'name': 'link 1',
    'pattern': 'fe:upload'
  },
  {
    'name': 'link 2',
    'pattern': 'fe:download'
  }
]

It will work hardcoded like this:

<a href="{% url 'fe:upload' id %}">up</a>
<a href="{% url 'fe:download' id %}">down</a>

However I'm struggling to put it into a loop

my_template.html

<ul>
  {% for link in links %}
    <li>
      <a href='{% url link.pattern id %}'>{{link.name}}</a>
    </li>
  {% endfor %}
</ul>

I have tried:

escaping the quotations with \ and HTML entities
putting the href into a temp variable, eg: {% with href=url 'link.pattern' %} and get the error:

u'with' received an invalid token: u"'link.pattern'"

how can I put a dynamic pattern into this loop to generate an anchor?

@DanielRoseman I'm sorry, what do you mean with the original code? Which? — 1252748

The one you show in my_template.html. You showed the error when you used with, but what happened before you did that? — Daniel Roseman

Have you tried the following:

{% with link.pattern as link_pattern %}
    <li>
      <a href='{% url link_pattern id %}'>{{link.name}}</a>
    </li>
{% endwith %}

This seems to work! i thought that the with something=something.else was the same as the with/as pattern. How do they differ exactly? Thanks man!

Glad i could help!

I haven't used with something=something.else to be honest. I just remember that every time i need to have something dynamic inside a template tag i can just cast this something as a name variable which i can use inside.

Note, OP's problem was not as vs =, it was the bizarre use of href=url 'something'.

@DanielRoseman can you explain why that is bizarre? I’m new to the django landscape and I’ve inherited that bit. What would be more typical in your view?
