在视图 django 中比较表单的值

Question

View.py

类注册（模板视图）：

template_name = 'registration.html'

def get(self, request, *args, **kwargs):

    form = CreateForm()

    return render(request, self.template_name, {'form': form})

@staticmethod

def post(request):
    try:
        data = request.POST.get
        user = User(
            first_name=data('first_name'),
            last_name=data('last_name'),
            username=data('username').strip(),
            email=data('email'),
        )
        user.set_password(data('password').strip())
        user.save()
        request.session["user_id"] = user.id
        return HttpResponse(' Save successfully ')

    except Exception as c:
        return HttpResponse("Failed :  {}".format(c), 500)

Form.py

role_choice= (("Customer", "Customer"), ("Employee", "Employee"))

类 CreateForm(forms.Form):

first_name = forms.CharField(label="Enter Your First Name", max_length=30, required=True)

last_name = forms.CharField(label="Enter Your Last Name", max_length=30, required=True)

username = forms.CharField(required=True, widget=forms.TextInput())

email = forms.CharField(required=True, widget=forms.TextInput())

password = forms.CharField(required=True, widget=forms.PasswordInput())

role = forms.ChoiceField(choices=role_choice, widget=forms.RadioSelect())

类客户（forms.Form）：

contact = forms.IntegerField(label="Enter your contact number", required=True, )

amount = forms.IntegerField(required=True, min_value=500)

type = forms.ChoiceField(choices=choice)

Model.py

类客户（models.Model）：

user = models.ForeignKey(User, on_delete=models.CASCADE)

contact = models.BigIntegerField()

amount = models.BigIntegerField()

type = models.CharField(max_length=1)

模板

{% 扩展“home.html” %}

{% 加载crispy_forms_tags %}

{% block title %}创建帐户{% endblock %}

{% 块内容 %}

<div>

    {% csrf_token %}

    {{ form|crispy }}

  <button type="submit">Submit</button><br>

</div>

{% 端块 %}

注册后，当用户在提交表单后选择客户选项时，如果用户选择员工选项，我会转到客户页面，他/她会转到员工页面，但我不知道该怎么做

首先，我强烈建议不要自己写所有的观点等等。 Django 已经拥有很多工具。它有一个可以稍微修改的UserCreationForm [Django-doc]。例如：

# app/forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm

class RoleUserCreationForm(UserCreationForm):
    ROLES = (
        ('Customer', 'Customer'),
        ('Employee', 'Employee')
    )
    role = forms.ChoiceField(choices=ROLES, widget=forms.RadioSelect())

    class Meta(UserCreationForm.Meta):
        fields = (*UserCreationForm.Meta.fields, 'first_name', 'last_name')

因此，我们可以在这里为first_name 和last_name 添加额外的字段。

现在我们可以在CreateView [Django-doc] 中使用它，并覆盖form_valid(..) method [Django-doc]：

# app/views.py

from app.forms import RoleUserCreationForm
from django.contrib.auth import get_user_model
from django.shortcuts import redirect
from django.views.generic.edit import CreateView

class RegisterView(CreateView):
    model = get_user_model()
    form_class = RoleUserCreationForm

    def form_valid(self, form):
        request.session['user_id'] = self.object.id
        if form.cleaned_data['role'] == 'Customer':
            return redirect('name-of-customer-view')
        else:
            return redirect('name-of-employee-view')

您将 'name-of-customer-view' 和 'name-of-employee-view' 分别替换为这些视图的名称。
