Django:来自 View 的初始值

Question

如何从 View 中获取初始值？我应该在表单中使用什么参数？

View .py

def cadastro_usuario(request):
    if request.method == 'POST':
        form = cadastroForm(request.POST)
        if form.is_valid():            
            new_user = form.save()
            return HttpResponseRedirect("/")
    else:
        form = cadastroForm()
    return render_to_response("registration/registration.html", {
        'form': form, 'tipo_cadastro': 'PF',})

表格.py

class cadastroForm(UserCreationForm):

    tipo_cadastro = forms.CharField(XXXXX)

好的，根据您对@J 的评论。 Lnadgrave，让我们假设您的 UserProfile 模型上有一个“user_type”属性，可以设置为您的“普通”用户或“公司”用户...

#your_app.constants
NORMAL_USER = 0
COMPANY_USER = 1

USER_TYPE_CHOICES = (
    (NORMAL_USER, "Normal"),
    (COMPANY_USER, "Company"),
)


#your_app.models
from django.contrib.auth.models import User
from your_app.constants import USER_TYPE_CHOICES

class UserProfile(models.Model):
    user = models.OneToOne(User)
    user_type = models.PositiveSmallIntegerField(choices=USER_TYPE_CHOICES)


#your_app.forms
from your_app.models import UserProfile

class UserProfileForm(forms.ModelForm):
    class Meta():
        model = UserProfile

    user_type = forms.IntegerField(widget=forms.HiddenInput)


#your_app.views
form django.http import HttpResponseRedirect
from django.shortcuts import render
from your_app.constants import NORMAL_USER, COMPANY_USER
from your_app.forms import UserProfileForm
from your_app.models import UserProfile

def normal_user_registration(request):
    user_profile_form = UserProfileForm(request.POST or None,
        initial={'user_type' : NORMAL_USER})
    if request.method == 'POST':
        user_profile_form.save()
        return HttpResponseRedirect('/')
    return render(request, 'registration/registration.html',
        {'user_profile_form' : user_profile_form})

def company_user_registration(request):
    user_profile_form = UserProfileForm(request.POST or None,
        initial={'user_type' : COMPANY_USER})
    if request.method == 'POST':
        user_profile_form.save()
        return HttpResponseRedirect('/')
    return render(request, 'registration/registration.html',
        {'user_profile_form' : user_profile_form})

这是一个相当冗长的方法来解决这个问题，但我认为它使如何将初始值传递给您的表单非常明显。希望能帮到你。
