Question

我已经能够创建一个表单，用户可以在tutorial之后输入用户名和密码。

我希望能够通过以下方式创建用户帐户：按下一个按钮，将用户转移到另一个页面，在那里他们将填写表格并将详细信息保存到数据库中。我还想确保不重复用户名。但是，我不知道如何编码。我对django很新，因此我为什么要挣扎。

我正在使用Windows和原子代码编辑器，如果这有所不同。请有人帮我编码。

你可以关注this youtube tutorial，这对我很有帮助，如果你完全遵循它，你会更熟悉django配置。

此外，您可以按照以下步骤操作：

1.-使用以下代码
在app目录中创建forms.py文件
```
BufferedIOBase
```

2.-然后你必须在app目录中创建view.py文件（如果没有创建）



# we import the django default user model
from django.contrib.auth.models import User
# also, import the forms to create em
from django import forms

# define a class for your form, it can be anithing you want
class UserForm(forms.ModelForm):
    # password = forms.CharField(widget=forms.PasswordInput)
    # this Meta class is the way we send information for our form
    class Meta:
        # define the model
        model = User
        # define the fields you need (note that username and password are required)
        fields = [
            'password',
            'username',
            'first_name',
            'last_name',
            'is_staff',
            'email',
        ]
        # then, in widgets you can define the input type of the field and give
        # attributes to each one
        widgets = {
            'password': forms.PasswordInput(attrs={'class': 'form-control', 'name': 'username'}),
            'username': forms.TextInput(attrs={'class': 'form-control', 'name': 'username', 'placeholder': 'username'}),
            'first_name': forms.TextInput(attrs={'class': 'form-control', 'name': 'first_name', 'placeholder': 'First Name'}),
            'last_name': forms.TextInput(attrs={'class': 'form-control', 'name': 'last_name', 'placeholder': 'Last Name'}),
            'is_staff': forms.CheckboxInput(attrs={'class': 'form-control', 'name': 'is_staff'}),
            'email': forms.TextInput(attrs={'class': 'form-control', 'name': 'email', 'placeholder': 'email'}),
        }

3.-在urls.py文件中添加路径

# we import the django default user model
from django.contrib.auth.models import User
# also, import the forms to create em
from django import forms

# define a class for your form, it can be anithing you want
class UserForm(forms.ModelForm):
    # password = forms.CharField(widget=forms.PasswordInput)
    # this Meta class is the way we send information for our form
    class Meta:
        # define the model
        model = User
        # define the fields you need (note that username and password are required)
        fields = [
            'password',
            'username',
            'first_name',
            'last_name',
            'is_staff',
            'email',
        ]
        # then, in widgets you can define the input type of the field and give
        # attributes to each one
        widgets = {
            'password': forms.PasswordInput(attrs={'class': 'form-control', 'name': 'username'}),
            'username': forms.TextInput(attrs={'class': 'form-control', 'name': 'username', 'placeholder': 'username'}),
            'first_name': forms.TextInput(attrs={'class': 'form-control', 'name': 'first_name', 'placeholder': 'First Name'}),
            'last_name': forms.TextInput(attrs={'class': 'form-control', 'name': 'last_name', 'placeholder': 'Last Name'}),
            'is_staff': forms.CheckboxInput(attrs={'class': 'form-control', 'name': 'is_staff'}),
            'email': forms.TextInput(attrs={'class': 'form-control', 'name': 'email', 'placeholder': 'email'}),
        }

4.-最后只需在html文件中添加表单


    # import the View form django and the UserForm we created on step 1
    from django.views.generic import View
    from .forms import UserForm
    # And some other things we need
    from django.core.urlresolvers import reverse_lazy
    from django.http import HttpResponseRedirect
    from django.contrib.auth.models import User # we also need this one
    from django.shortcuts import render
    from django.contrib import messages
    from django.views import generic

# create the class view, named as you need
class UserFormView(View):
    # define the form to use, in this case the form we created
    form_class = UserForm
    # define the template_name, your main html file wher your are goin to use the form
    template_name = 'usersControll/add.html'
    # and the reverse_lazy is helpfull when the user succesfully added a new user
    # replace 'users-add' with the name of your rute 
    success_url = reverse_lazy('users-add')

    def get(self, request):
        form = self.form_class(None)
        return render(request, self.template_name, {'form': form})

    def post(self, request):
        form = self.form_class(request.POST)

        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form, request)

    def form_valid(self, form):
        # when the info the user gave us is valid, stop the commit 
        # so we can give some nice format to this info
        user = form.save(commit=False)
        # the "form.cleaned_data" help us to give a standar format to the info
        username = form.cleaned_data['username']
        first_name = form.cleaned_data['first_name']
        last_name = form.cleaned_data['last_name']
        password = 'tempPass'
        user.set_password(password)
        # aaand we save it to the database
        user.save()

        # in my case a send a succesfull massage to the user indicating that
        # went fine
        messages.add_message(self.request, messages.SUCCESS, "El usuario <b>form.cleaned_data['first_name']</b> fue registrado exitosamente.")
        return super(UserFormView, self).form_valid(form)

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

希望这对你有用。
