Perplexing many-to-many problem
===============================
When attempting to iterate a many-to-many relationship of a context
variable, I am receiving a weird template error.
Any help would be greatly appreciated!
My Models
---------
Person()
projects = models.ManyToManyField(Task, blank=True)
Task()
Middleware
----------
- custom middleware which is inserting person into request (very
similar to contrib.auth)
- request context processor which puts request into my template
What Works as Expected
----------------------
{{ request.person.name }} works fine
{{ request.person.company.name }} (where company is a FK) works fine
{{ request.person.projects }} returns
<django.db.models.fields.related.ManyRelatedManager object at
0x01564B10>
{% for project in request.person.notaproperty %} skips the for loop as
expected
{% for project in request.person.projects %} returns an "iteration over
non-sequence" as expected (a ManyRelatedManager isn't iterable, the
.all() queryset is)
What Doesn't (aka, The Problem)
-------------------------------
{% for project in request.person.projects.all %}
It returns a template error. Here are the final lines of the traceback:
File "D:\Web\Python24\lib\site-packages\django\db\models\query.py" in

734. joins2, where2, params2 = lookup_inner(path, lookup_type, value,
opts, opts.db_table, None)
