Django – Use a template tag within a template tag?

I am trying to write a simple Django view that prints out a table representing all the fields in a model.

I have a model called Menu_Items, with 6 fields:

Item_Id
Name
Description
Base_Price
Image_Path
Item_Tags

Using Menu_Items._meta.fields I can retrieve the list of fields.

For a given queryset (e.g. Menu_Items.objects.all()) I would like to print out all of the fields, formatted as a table.

I've tried passing the fields in the context, but I cannot figure out which template tag to use. Is it possible to use a template tag inside of a template tag? like so:

{% for field in fields %}
    {{ menuItems.0.{{ field.name }} }}
    {{ field.name }}
{% endfor %}

In this case, the field is each of the fields returned by Menu_Items._meta.fields

Instead of doing this, change your query so it returns a ValueQuerySet with values().

Your result will be a list of dictionaries, here is an example from the documentation:

>>> Blog.objects.filter(name__startswith='Beatles').values()
[{'id': 1, 'name': 'Beatles Blog', 'tagline': 'All the latest Beatles news.'}]

Now, in your template:

{% for item in results %}
   {% for column,value in item.iteritems %}
       {{ column }} {{ value }}
   {% endfor %}
{% endfor %}

This will result in:

id 1
name Beatles Blog
tagline All the latest Beatles news.
