问题 TLDR Question: How do you make one crispy form with a ¿segmented?(not sure if this is considered inline) layout with multiple models(some related, some not). I am trying to understand several things in Django: forms, formsets, nested forms, and crispy, and I've been at it for a while, and feel I am close, just need someone to help connect the dots. I'm not sure how to accomplish it without crispy, so I started down this path thinking crispy was the solution. Please correct if I am wrong,

问题 I don't understand, why is my model clean method called before full form validation. I have required fields in my form. If I don't fill them, I don't get form errors, instead of, the model clean method is called (so I suppose it's because save is called). It crashes in models clean() method: if self.date_from > self.date_to can't compare datetime.date to NoneType Because I didn't filled date_to field. I think that form should have handle it and raise ValidationError and models save() shouldn

问题 I am converting a survey from a Form to a ModelForm in Django 1.6.2. Can anyone tell me what is the equal of forms.ChoiceField(widget=forms.Select(), and forms.ChoiceField(widget=forms.RadioSelect() using ModelForm ?

问题 I want to make a form used to filter searches without any field being required. For example given this code: models.py: class Message(models.Model): happened = models.DateTimeField() filename = models.CharField(max_length=512, blank=True, null=True) message = models.TextField(blank=True, null=True) dest = models.CharField(max_length=512, blank=True, null=True) fromhost = models.ForeignKey(Hosts, related_name='to hosts', blank=True, null=True) TYPE_CHOICES = ( (u'Info', u'Info'), (u'Error', u

问题 Given the following models (cut down for understanding): class Venue(models.Model): name = models.CharField(unique=True) class Band(models.Model): name = models.CharField(unique=True) class Event(models.Model): name = models.CharField(max_length=50, unique=True) bands = models.ManyToManyField(Band) venue = models.ForeignKey(Venue) start = models.DateField() end = models.DateField() The admin area works great for what I'm doing, but I'd like to open the site up a bit so that certain users can

问题 I have a Person model, which has a ForeignKey field to itself, called mother . When the user goes to the 'add' admin form, I want to define an initial value for mother , in case there is a GET('mother') parameter, or leave it blank, in case there is not.

In models.py: class Person(models.Model): name=models.CharField() mother=models.ForeignKey('self') In admin.py: class

问题 I'm making a custom user form where a user can go in to change some details. It got two errors that I cannot understand what the problem is though. The first problem is that the form doesn't fill out the user details. And it seems to be because self is empty when form is initialized, why? And the second problem is that when I submit this form, it will complain about some KeyError, which I don't get either. I've pasted the code and stacktrace. Trackback Environment: Request Method: POST
