Advise how to solve it would be highly appreciated. Thank you in advance. views.py from django.shortcuts import render from .forms import modelformset_factory, AssumptionsForm from .models import Assumptions def get

问题 I have a very simple model for tracking events: class Event(models.Model): description = models.TextField() location = models.ForeignKey(Location) start = models.TimeField() duration = models.IntegerField() event_date = models.DateField() creator = models.ForeignKey(User) and I opted to extract the location in a separate table in order to be able to perform queries: class Location(models.Model): city = models.CharField(max_length=20) address = models.CharField(max_length=30). What would be

问题 I have a multiple ModelForm classes that each represent a different Model. I would like to have a generic 'create' function that loads the specified model form based on a URL parameter. It is possible to load a model dynamically with this: model_name = 'TestModel' m = get_model('AppLabel', model_name) Does anyone know how I can achieve the same for ModelForms, something like: modelform_name = 'TestModelForm' f = get_form('AppLabel', modelform_name) if f.is_valid(): ... I can not think of a

问题 I extended the User model in django to include several other variables, such as location, and employer. Now I'm trying to create a form that has the following fields: First name (from User) Last name (from User) Location (from UserProfile, which extends User via a foreign key) Employer (also from UserProfile) I have created a modelform: from django.forms import ModelForm from django.contrib import auth from alert.userHandling.models import UserProfile class ProfileForm(ModelForm): class Meta:

问题 In a ModelForm, i have to test user permissions to let them filling the right fields : It is defined like this: class TitleForm(ModelForm): def __init__(self, user, *args, **kwargs): super(TitleForm,self).__init__(*args, **kwargs) choices = ['','----------------'] # company if user.has_perm("myapp.perm_company"): self.fields['company'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Company.objects.all(), required=False) choices.append(1,'Company') # association if user.has_perm

问题 I've a modelform and I excluded two fields, the create_date and the created_by fields. Now I get the "Not Null" error when using the save() method because the created_by is empty. I've tried to add the user id to the form before the save() method like this: form.cleaned_data['created_by'] = 1 and form.cleaned_data['created_by_id'] = 1 . But none of this works. Can someone explain to me how I can 'add' additional stuff to the submitted modelform so that it will save? class Location(models

I want the Model_Sub to be seamlessly included with the main

问题 Is there a way to autocreate forms based on the models I defined within Doctrine? In Django its a basic feature. I found some old sources where someone had tried to implement it by himself... but nothing up-to-date or official-looking These model forms save loads of time. I do ask myself why people don't complain about this (possibly) missing feature... 回答1: Zend 2 cannot create a form from the Entity itself. Doctrine 2 is not even part of the framework or tied to it as close as to Symfony 2.
