Hello guys, I think this is more a python question than Django.
But basically I'm doing at Model A:
from myproject.modelb.models import ModelB
and at Model B:
from myproject.modela.models import ModelA
Result:
cannot import name ModelA
Am I doing something...

So, instead.
In Django you can fix this by referring to a model by name instead of by class object.

(That is, the model that you pass to the view and the model that you get back once the form posts.)
If not, is it better to do so anyways? What if there is data you are gathering that is beyond what the view page model has a property for?

Hello guys,
I've looked at formset and model formset at Django many times, but I still can't figure the smart way to do this.

Person
I have a queryset that contains all the persons trying to join a particular group: Person.objects...

In your view, check the value of the hidden field to... .
On the onclick event of the Accept and Reject buttons, set the value of the hidden field appropriately and then submit the form .

It used to be that within a CodeIgniter model you couldn't access another model. E.g
$this->load->model('bar'); $this->bar->something();
Would be invalid within the code of a model. Is this still valid or have they changed it?

I have a model with a FileField and a form that has a FileField as well. The form is not a ModelForm based on the model but it's a regular Form.
How do I save the uploaded file from the form to the model?

If your model is
class Thing(models.Model): document = models.FileField(upload_to='documents')
you can.

I want to apply the "ordering" Meta option to the Django model User from django.contrib.auth.models. Normally I would just put the Meta class in the model's definition, but in this case I did not define the model. So where do I put the Meta class to modify...

The only issue with it is that you need....
The standard User model has no ordering defined support.
This is how the Django manual recommends you do it :
You could also use a proxy model to define a different default ordering on a model.

I have a model and two views set up like this:

You'll have to send the model index through the proxy model by platform.
These will pass you a model index.
I'm not sure if this would work, and it depends on what Qt .

I have a dialog box with two disctinct parts. Each part uses a model view design.
But when a model is updated, the second one has to be updated too. I’m wondering if it exists any best pratice or design pattern for communicating (update notification) ...

If each model can.
A common solution is to have the second model listen to the first model and update itself when the first model fires a change event.
You could use the Mediator design pattern.
