Piotr,
Unfortunately, you have received a lot of very bad advice in this thread,
for which I can only apologise on behalf of Django-users ...
The references to your custom Managers are misleading. Although it's true
that you don't need them, because they're not changing anything, you aren't
in fact breaking anything by having them - just defining them with a "pass"
doesn't, as some people apparently think, mean that they now have no content
- of course it doesn't, because you inherit from models.Manager, soo you'll
have all the default code of that class. Still, as I say, because you don't
change anything, you don't need them.
The main weird thing in the code you have posted is these two lines in the
CampPeople model:
docall = models.BooleanField(True)
called = models.BooleanField(False)
Now, the first parameter to a model field (apart from ForeignKeys) is the
verbose name - ie what appears as the prompt when you create a form based on
that model. So it seems you have True and False as the verbose names, which
I'm sure isn't what you want - but I'm not certain what it is you *do*
intend here. Are you hoping that these will be the default values? If so,
you need to use the `default` argument:
docall = models.BooleanField(default=True)
called = models.BooleanField(default=False)
Does that help at all?
You might also try putting some debugging into your template to see if
you're getting the results you think you are:
{% for piplok in camppeople %}
{{ piplok }}
