django-forms

问题 I'm trying to develop an e-commerce site with Django. So I'm at this point where, users can add items to their cart, but when I try to proceed to checkout, for some reason, my checkout form is not displayed rather, it says: Page not found (404) I made sure that I have registered my models, and ran migrations. What is the problem? My views.py: @login_required def checkout(request): address_form = UserAddressForm(request.POST or None) if address_form.is_valid(): new_address = address_form.save

问题 I want to have multiple dropdowns, each showing the available objects from one specific model. So Dropdown 1: Apples Oranges Pears and, Dropdown 2: Apples Oranges Pears etc. The bonus question is to have these dropdowns linked/be dependent so that as the user selects items, these chosen items are removed from the remaining dropdowns. Is this possible? 回答1: It is possible. Import your Model to the view-File. Example: def editUser(request): users = "YourModel".objects.all() if request.method=

问题 I have a Django form that is rendered with bootstrap3. I want to be able to pass parameters into my form to make it more generic. My forms looks like: class SpacecraftID(forms.Form): def __init__(self,*args,**kwargs): choices = kwargs.pop('choices') #self.choices = kwargs.pop('choices') produces same error super(SpacecraftID,self).__init__(*args,**kwargs) scID = forms.MultipleChoiceField(required=False, widget=forms.CheckboxSelectMultiple, choices=choices) And my view looks like: def schedule

问题 I want to exclude those options from the ChoiceField in the forms that has been already selected and are into the database. Below is the Code. models.py SEMESTER_CHOICES = ( ("1", "1"), ("2", "2"), ("3", "3"), ("4", "4"), ("5", "5"), ("6", "6"), ("7", "7"), ("8", "8"), ) class Publish(models.Model): dates = models.CharField(max_length=255, choices = SEMESTER_CHOICES) def __str__(self): return self.dates form.py SEMESTER_CHOICES = ( ("1", "1"), ("2", "2"), ("3", "3"), ("4", "4"), ("5", "5"), (

问题 I have a form whose queryset depends on request.user, and whose initial value depends on a session key. The primary models are User (slight modification of default User model) and Account, with a many-to-many relationship between them. The form allows a User to change the Account that he/she is viewing, and that choice must persist as the User navigates the site. The form works fine when created in a single view and passed to a single template, but I want the form to appear in the top
