python - Django:我的表单没有持久保存在数据库中

Question

我这里有以下结构:

模型.py:

class MyUser (models.Model):
    name = models.CharField(max_lenght=255, required=True)
    password = models.CharField(max_lenght=255, required=True)
    phone = models.CharField(max_lenght=255, required=True)
    company = models.CharField(max_lenght=255,required=True)
    user = models.OneToOneField(User, related_name="client")
    @property
    def email(self):
       return self.user.email

表单.py:

from django import forms
from django.contrib.auth.models import User

class MyUserForm(forms.Form):
    name= forms.CharField(required=True)
    email = forms.EmailField(required=True)
    pass = forms.CharField(required=True)
    phone = forms.CharField(required=True)
    company = forms.CharField(required=True)
    def is_valid(self):
        valid = True
        if not super(MyUserForm, self).is_valid():
            self.adiciona_erro('Error. Pleas correct the form.')
            valid = False
        user_exists = User.objects.filter(username=self.data['name']).exists()
        if user_exists:
            self.adiciona_erro('User already exists.')
            valid = False
        return valid
   def adiciona_erro(self, message):
        errors = self._errors.setdefault(forms.forms.NON_FIELD_ERRORS, forms.utils.ErrorList())
        errors.append(message)

和 views.py:

class MyUserView(View):

    def get(self, request):
       return render(request, self.template_name)

    def post(self, request):

        form = MyUserForm(request.POST)

        if form.is_valid():
            dados_form = form.data

            user = User.objects.create_user(dados_form['name'], dados_form['email'], dados_form['pass'])            

            client = Client(name=dados_form['name'], 
                            email=dados_form['email'], 
                            phone=dados_form['phone'],
                            nome_empresa=dados_form['company'],
                            user=user)

            ###########################################
            #SHOULD SAVE ON DATABASE, NO?
            client.save()
            ###########################################

            return redirect('index')

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

一切正常，除了保存在数据库中。我需要使用 Form 类，因为我想个性化我的网页。为什么不保存到数据库中？

我正在使用 postgree。

非常感谢。

Answer 1

首先，你不应该覆盖 is_valid()在你的表格中。您应该覆盖 clean_<fieldname>方法(例如 clean_name )或 clean反而。查看docs on form validation获取更多信息。你的adiciona_erro方法看起来没有必要。只需提高 ValidationError , 或调用 add_error

其次，如果表单有效，您应该访问 form.cleaned_data 中的值而不是 form.data .

如果您在进行这些更改后仍然遇到困难，则需要添加有关无效内容的更多信息。是 post方法被调用？是form.is_valid()返回 True或 False .如果是 False , 什么是表单错误？
