Django表单与两个不同的模型的字段 [英] Django form with fields from two different models

问题描述

我需要显示一个表单，其中有两个不同模型的多个字段。
表单只包含模型中的部分字段，布局将使用脆性表单。

I need to display one form, with multiple fields from 2 different models. Form will contain only part of fields from models, and layout will be made using the crispy forms.

我的模型：

class Company(BaseModel):
    title = models.CharField(_('Company'), max_length=128)
    domain = models.CharField(_('Domain'), max_length=128)
class Account(BaseModel):
    company = models.ForeignKey(Company)
    user = models.OneToOneField(User)
    role = models.CharField(_('Role'), choices=ROLES, default='member', max_length=32)

我想以表单显示的字段：
公司标题，用户名，用户姓氏，用户电子邮件

Fields which I want to show in form: company title, user first name, user last name, user email

是甚至有可能吗我该怎么做？

Is it even possible? How can I do this?

推荐答案

在您的forms.py

In your forms.py

from django import forms


class YourForm(forms.Form):
    title = forms.CharField()
    first_name = forms.CharField()
    last_name = ...

在您的views.py

In your views.py

from forms import YourForm
from django import views
from models import Company, Account

class YourFormView(views.FormView)
    template_name = 'some_template.html'
    form_class = YourForm
    success_url = '/thanks/'

    def form_valid(self, form):
        title = form.cleaned_data['title']
        ...
        # do your processing here using Company and Account
        # i.e. company = Company.objects.create(title=title, ...)
        #      account = Account.objects.get_or_create(
        #      user=..., company=company ...)
        #      ... more processing
        #
        # Call company.save() and account.save() after adding
        # your processed details to the relevant instances
        #  and return a HttpResponseRedirect(self.success_url)

    def is_valid(self):
        # don't forget to validate your fields if need be here

像往常一样，文档很有帮助。
https://docs.djangoproject.com/en/1.7/topics/表单/

As usual the docs are pretty helpful. https://docs.djangoproject.com/en/1.7/topics/forms/
