Rendering a dictionary in Jinja2

jinja2, python

Solution

Your `url_list` should look like this:

url_list = [{'target': 'http://10.58.48.103:5000/', 'clicks': '1'}, 
            {'target': 'http://slash.org', 'clicks': '4'},
            {'target': 'http://10.58.48.58:5000/', 'clicks': '1'},
            {'target': 'http://de.com/a', 'clicks': '0'}]

Then using:

<li>{{ item["target"] }}</li>

in your template will work.

Edit 1:

Your template think you're passing a list in, so are you sure you're passing in your original dict and not my above list?

Also you need to access both a `key` and a `value` in your dictionary (when you're passing a dictionary rather than a list):

Python 2.7

{% for key, value in url_list.iteritems() %}
    <li>{{ value["target"] }}</li> 
{% endfor %}

Python 3

{% for key, value in url_list.items() %}
    <li>{{ value["target"] }}</li> 
{% endfor %}

Problem

I'm playing with a url shortener (basing it on the Shortly demo app from Werkzeug). I have a dict like this - ``` ('1', {'target': 'http://10.58.48.103:5000/', 'clicks': '1'}) ('3', {'target': 'http://slash.org', 'clicks': '4'}) ('2', {'target': 'http://10.58.48.58:5000/', 'clicks': '1'}) ('5', {'target': 'http://de.com/a', 'clicks': '0'}) ``` which is returned in url_list and used by render_template ``` def on_list_urls(self, request): url_list = self.get_urls() return self.render_template('list_urls.html', url_list = url_list ) ``` the template list_urls is pretty simple - ``` {% extends "layout.html" %} {% block title %}List URLs{% endblock %} {% block body %} <h2>List URLs</h2> <ul id="items"> {% for item in url_list %} <li>{{ item }}</li> {% endfor %} </ul> {% endblock %} ``` Thing is, I can't seem to access the items in the dict. The line ``` <li>{{ item }}</li> ``` is where I'm focussing attention. As above, I get a list of the keys in the dict. ``` <li>{{ item["target"] }}</li> ``` returns nothing. None of the {{ user.url }}">{{ user.username }} type stuff in the docs seems to work. Ideas please? Newbie - be gentle. Thanks. Update Thanks for the responses. Ewan's answer works, but uses a list of dicts. I want to pass a dict and render that (because I want a non-integer index of items). Does Jinja do that? Also - I mis-represented url_list. It's more like this - ``` {'a': {'target': 'http://testing.com/test', 'clicks': '0'}, '1': {'target': 'http://10.58.48.103:5000/', 'clicks': '1'}, '3': {'target': 'http://slash.org', 'clicks': '4'}, '2': {'target': 'http://10.58.48.58:5000/', 'clicks': '1'}} ``` Further experimentation - passing a dict produces an error about a list object. ``` {% for key in url_list.iteritems() %} ``` UndefinedError: 'list object' has no attribute 'iteritems' Thanks again. Still baffled by why it thought I was passing a list but got it working now. ``` {% for key, value in url_list.iteritems() %} <li>{{ key }} - {{ value["target"] }} - {{ value["clicks"] }}</li> ``` prints out everything. Many thanks.
