Question

我试图比较密码和确认密码。如果我输入其他密码，它不会引发错误并重定向到登录页面。

models.py

class reg1(models.Model):
    name=models.CharField(max_length=100)
    city=models.CharField(max_length=100)
    email=models.CharField(max_length=100)
    username=models.CharField(max_length=100)
    password=models.CharField(max_length=100)
    cpassword=models.CharField(max_length=100)
    class Meta:
        db_table='reg1'

forms.py

class regform(forms.Form):
    name = forms.CharField(max_length=100)
    city = forms.CharField(max_length=100)
    email = forms.CharField(max_length=100)
    username = forms.CharField(max_length=100)
    password = forms.CharField(max_length=100)
    cpassword=forms.CharField(max_length=100)

    def clean_password(self):
        if self.data['password'] != self.data['cpassword']:
            raise forms.Error('Passwords are not the same')
        return self.data['password']

views.py

if myregform.is_valid():
    name1 = myregform.cleaned_data['name']
    city1 = myregform.cleaned_data['city']
    email = myregform.cleaned_data['email']
    username1 = myregform.cleaned_data['username']
    password1 = myregform.cleaned_data['password']
    password2=myregform.cleaned_data['cpassword']
    a=reg1(name=name1,city=city1,email=email,
         username=username1,password=password1,cpassword=password2)
    a.save()

我希望输出，因为我输入了不同的密码，它将显示密码不匹配的错误

我正在使用带有sqlite3数据库的pycharm软件和django框架。

使用ModelForm可以节省大量输入。
您需要使用clean()来验证与其他字段相关的数据。
您需要加注ValidationErrors。

class reg1(models.Model):
    name = models.CharField(max_length=100)
    city = models.CharField(max_length=100)
    email = models.CharField(max_length=100)
    username = models.CharField(max_length=100)
    password = models.CharField(max_length=100)
    cpassword = models.CharField(max_length=100)

    class Meta:
        db_table = "reg1"


class regform(forms.ModelForm):
    class Meta:
        model = reg1
        exclude = ()

    def clean(self, cleaned_data):
        if cleaned_data["password"] != cleaned_data["cpassword"]:
            raise forms.ValidationError("Passwords are not the same")
        return cleaned_data


# ...

if myregform.is_valid():
    a = myregform.save()

Django表单中未显示密码确认错误
