Python 将Django模型基于表单的系统转换为原始的基于HTML的表单系统，以便注册

我有一个基于类的视图系统，用于注册

Django

，它使用Django的模型表单。但是我需要呈现我的自定义构建

HTML

表单来代替它

My型号.py：

from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
    is_student = models.BooleanField(default=False)
    is_teacher = models.BooleanField(default=False)

class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    quizzes = models.ManyToManyField(Quiz, through='TakenQuiz')
    interests = models.ManyToManyField(Subject, related_name='interested_students')

class StudentSignUpView(CreateView):
    model = User
    form_class = StudentSignUpForm
    template_name = 'registration/signup_form.html'

    def get_context_data(self, **kwargs):
        kwargs['user_type'] = 'student'
        return super().get_context_data(**kwargs)

    def form_valid(self, form):
        user = form.save()
        login(self.request, user)
        return redirect('students:quiz_list')

class StudentSignUpForm(UserCreationForm):
    interests = forms.ModelMultipleChoiceField(
        queryset=Subject.objects.all(),
        widget=forms.CheckboxSelectMultiple,
        required=True
    )

    class Meta(UserCreationForm.Meta):
        model = User

    @transaction.atomic
    def save(self):
        user = super().save(commit=False)
        user.is_student = True
        user.save()
        student = Student.objects.create(user=user)
        student.interests.add(*self.cleaned_data.get('interests'))
        return user

和视图。py：

from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
    is_student = models.BooleanField(default=False)
    is_teacher = models.BooleanField(default=False)

class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    quizzes = models.ManyToManyField(Quiz, through='TakenQuiz')
    interests = models.ManyToManyField(Subject, related_name='interested_students')

class StudentSignUpView(CreateView):
    model = User
    form_class = StudentSignUpForm
    template_name = 'registration/signup_form.html'

    def get_context_data(self, **kwargs):
        kwargs['user_type'] = 'student'
        return super().get_context_data(**kwargs)

    def form_valid(self, form):
        user = form.save()
        login(self.request, user)
        return redirect('students:quiz_list')

class StudentSignUpForm(UserCreationForm):
    interests = forms.ModelMultipleChoiceField(
        queryset=Subject.objects.all(),
        widget=forms.CheckboxSelectMultiple,
        required=True
    )

    class Meta(UserCreationForm.Meta):
        model = User

    @transaction.atomic
    def save(self):
        user = super().save(commit=False)
        user.is_student = True
        user.save()
        student = Student.objects.create(user=user)
        student.interests.add(*self.cleaned_data.get('interests'))
        return user

该系统还有一个form.py，它完成了艰苦的工作并呈现了

Django

模型表单。现在，我需要将这些类型的Django的默认模型表单替换为我的自定义构建

HTML

表单，类似这样的表单。 如何使用以下类型的简单系统，从

views.py

接收数据并创建用户

if request.method == 'POST':
    this_username = request.POST['username']
    this_password = request.POST['password']
    this_otherKindofStuff = request.POST['otherKindofStuff']
    Student_signup = Student.objects.create(name=this_name, password=this_password, otherKindofStuff=this_otherKindofStuff)
    Student_signup.save()

当前表单.py：

from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
    is_student = models.BooleanField(default=False)
    is_teacher = models.BooleanField(default=False)

class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    quizzes = models.ManyToManyField(Quiz, through='TakenQuiz')
    interests = models.ManyToManyField(Subject, related_name='interested_students')

class StudentSignUpView(CreateView):
    model = User
    form_class = StudentSignUpForm
    template_name = 'registration/signup_form.html'

    def get_context_data(self, **kwargs):
        kwargs['user_type'] = 'student'
        return super().get_context_data(**kwargs)

    def form_valid(self, form):
        user = form.save()
        login(self.request, user)
        return redirect('students:quiz_list')

class StudentSignUpForm(UserCreationForm):
    interests = forms.ModelMultipleChoiceField(
        queryset=Subject.objects.all(),
        widget=forms.CheckboxSelectMultiple,
        required=True
    )

    class Meta(UserCreationForm.Meta):
        model = User

    @transaction.atomic
    def save(self):
        user = super().save(commit=False)
        user.is_student = True
        user.save()
        student = Student.objects.create(user=user)
        student.interests.add(*self.cleaned_data.get('interests'))
        return user

我的HTML模板：

from django.contrib.auth.models import AbstractUser
from django.db import models

class User(AbstractUser):
    is_student = models.BooleanField(default=False)
    is_teacher = models.BooleanField(default=False)

class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    quizzes = models.ManyToManyField(Quiz, through='TakenQuiz')
    interests = models.ManyToManyField(Subject, related_name='interested_students')

class StudentSignUpView(CreateView):
    model = User
    form_class = StudentSignUpForm
    template_name = 'registration/signup_form.html'

    def get_context_data(self, **kwargs):
        kwargs['user_type'] = 'student'
        return super().get_context_data(**kwargs)

    def form_valid(self, form):
        user = form.save()
        login(self.request, user)
        return redirect('students:quiz_list')

class StudentSignUpForm(UserCreationForm):
    interests = forms.ModelMultipleChoiceField(
        queryset=Subject.objects.all(),
        widget=forms.CheckboxSelectMultiple,
        required=True
    )

    class Meta(UserCreationForm.Meta):
        model = User

    @transaction.atomic
    def save(self):
        user = super().save(commit=False)
        user.is_student = True
        user.save()
        student = Student.objects.create(user=user)
        student.interests.add(*self.cleaned_data.get('interests'))
        return user

根据您的评论：

我只是想建立我的自定义表单与HTML的这份工作

我从中了解到的是，您希望设计自己的HTML表单，并取消Django的默认呈现？但是能够利用Django的形式逻辑

如果是这种情况，您只需将表单数据收集到视图中，即可将自定义字段命名为与

ModelForm

中相同的名称，或者干脆将

form

命名为相同的名称。例如，如果您有如下表单：

来自django导入表单的

类MyForm（forms.Form）：
field=forms.CharField（）
field2=forms.IntegerField（）

如果您已经创建了视图并将

MyForm

实例传递给上下文数据，那么为该表单创建自定义HTML的方法如下：

...
{%csrf_令牌%}
领域
字段1

如果提交了上述表单，则

POST

ed数据将绑定到

MyForm

实例，您可以执行验证等操作，还可以通过访问

MyForm

实例的errors dict或per字段在模板中显示错误

除此之外，您当然可以使用Django表单

---

另外，你可能有兴趣尝试一下。如果您正在为HTML使用引导，这将是一个极好的补充。

显示当前的

forms.py

和模板codedited。。。。而且这个模板只有一个简单的jinja用于呈现Django的模型表单，所以你要做的是添加自定义样式或类，是吗？你能不能也在HTML模板中显示一个表单的片段？是的，我想要它。HTML模板也是通过一个代码段添加的。在这里，你可以说这个表单中没有自定义样式或类，但我稍后会添加它们。那么你能添加一个预期HTML输出的示例吗？非常感谢，这可能就是我想要的。我可以通过请求从views.py访问数据。POST['field']可能吗？是的。你可以。让我添加一个片段，说明将发布的数据绑定到表单后可以做些什么。
