I'm looking for an elegant way of stepping through my models from
within my template tags.
I have 3 model classes chained by many-to-many relationships, viz
Category --> Item --> Detail. This model pertains to resume data,
e.g., Category='Education', Item='Univ1', Detail='Biology
coursework'. Each model class has various subfields which I would
like to display on the final resume page.
I have tried various approaches involving {% for %} loops, and each
has resulted in failure. Each of my attempts requires using a
variable name as a model's attribute lookup. Unfortunately, it seem
the Django templating language attempts to access the variable's name,
not its value.
Approach 1):
I have pulled the field names from metadata in the view:
fields = []
for f in Item._meta.fields:
fields.append(f.column)
{% for c in categories %}
{% for i in c.items.all %}
{% for f in fields %}
{{ i.f }}
{% endfor %}
{% endfor %}
{% endfor %}
There's no resulting output, indicating Django was looking for an "f"
attribute to the Item instance contained in "i".
I was thinking about using a {% with %} block to concatenate the value
of "f" to the end of the "i" Item instance. It just seems incredibly
inelegant to have to explicitly list every field name I want
displayed.
Regards.
