我正在一个销售图像的网站上工作，我正在尝试找到一种方法，以便用户可以login注册后使用class基于视图，我已经使用基于函数的视图完成了它，但我想基于类进行它，因为它需要更少的代码。
下面是与function基于的观点：
My models.py:
from django.db import models
from django.contrib.auth.models import User
class JobType(models.Model):
job_name = models.CharField(max_length=50)
def __str__(self):
return self.job_name
class Country(models.Model):
country_name = models.CharField(max_length=50)
def __str__(self):
return self.country_name
class IndianState(models.Model):
state_name = models.CharField(max_length=30)
def __str__(self):
return self.state_name
class SignUpModel(User):
company_name = models.CharField(max_length=80)
job = models.ForeignKey(JobType, on_delete=models.CASCADE)
mobile_no = models.PositiveIntegerField()
country = models.ForeignKey(
Country, on_delete=models.CASCADE, blank=True)
state = models.ForeignKey(IndianState, on_delete=models.CASCADE)
forms.py
from django import forms
from django.contrib.auth.forms import AuthenticationForm, UsernameField
from django.utils.translation import gettext, gettext_lazy as _
from django.core import validators
from .models import JobType, SignUpModel
class MyAuthenticationForm(AuthenticationForm):
username = UsernameField(widget=forms.TextInput(attrs={'autofocus': True}))
password = forms.CharField(
label=_("Password"),
strip=False,
widget=forms.PasswordInput(attrs={'autocomplete': 'current-password'}),
)
error_messages = {
'invalid_login': _(
"Please enter a correct %(username)s and password."
),
'inactive': _("This account is inactive."),
}
class LoginForm(MyAuthenticationForm):
username = UsernameField(widget=forms.TextInput(
attrs={"autofocus": True, "class": 'form-control', 'placeholder': 'Enter Username'}), error_messages={'required': 'Enter Username'})
password = forms.CharField(
strip=False,
widget=forms.PasswordInput(
attrs={'placeholder': "Enter Password", 'class': 'form-control', 'auto-complete': 'current-password'}),
error_messages={'required': 'Enter Password'}
)
class SignUpForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['job'].empty_label = 'Select Job Description'
self.fields['country'].empty_label = 'Select Country'
self.fields['state'].empty_label = 'Select State'
first_name = forms.CharField(widget=forms.TextInput(
attrs={'placeholder': 'First Name', 'class': 'form-control'}), required=True, error_messages={'required': 'First Name is required'})
last_name = forms.CharField(widget=forms.TextInput(
attrs={'placeholder': 'Last Name', 'class': 'form-control'}), required=True, error_messages={'required': 'Last Name is required'})
email = forms.EmailField(widget=forms.EmailInput(
attrs={'placeholder': 'Email Address', 'class': 'form-control'}), required=True, error_messages={'required': 'Email Address is required'})
mobile_no = forms.CharField(widget=forms.NumberInput(
attrs={'placeholder': 'Mobile Number', 'class': 'form-control'}), validators=[validators.MinLengthValidator(10), validators.MaxLengthValidator(10)])
password = forms.CharField(widget=forms.PasswordInput(
attrs={'placeholder': 'Enter Password', 'class': 'form-control'}), validators=[validators.MinLengthValidator(8)], error_messages={'required': 'Enter Password'})
class Meta:
model = SignUpModel
fields = ['username', 'first_name', 'last_name', 'email', 'password',
'company_name', 'job', 'mobile_no', 'country', 'state']
widgets = {
'company_name': forms.TextInput(attrs={'placeholder': 'Company Name', 'class': 'form-control'}),
'mobile_no': forms.NumberInput(attrs={'placeholder': 'Mobile Number', 'class': 'form-control'}),
'username': forms.TextInput(attrs={'placeholder': 'Your Username', 'class': 'form-control'}),
'job': forms.Select(attrs={'class': 'form-control'}),
'country': forms.Select(attrs={'class': 'form-control'}),
'state': forms.Select(attrs={'class': 'form-control'})
}
error_messages = {
'username': {
'required': _('Username must be given')
},
'password': {
'required': _('password is required')
},
'mobile_no': {
'required': _('Mobile Number is required')
},
'company_name': {
'required': _('Company Name is required')
},
'job': {
'required': _('Job description must be selected')
},
'state': {
'required': _('State Name is required')
}
}
记住 ：在这里，我已经覆盖django's为我的目的而形成。
views.py
from django.http import HttpResponseRedirect
from django.shortcuts import render
from django.contrib.auth import authenticate, login, logout
from django.contrib import messages
from about.models import SignUpModel
from . forms import LoginForm
from django.views.generic.base import TemplateView
from django.contrib.auth.views import LoginView, LogoutView
from . forms import SignUpForm
from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required
from django.contrib.auth import authenticate, login

from django.contrib.auth import login, authenticate
# @cache_page(60*60*24)
def about_first_page(request):
return render(request, 'aboutus/home.html')
# @cache_page(60*60*24)

return render(request, 'aboutus/pricing.html')
class MyLoginView(LoginView):
template_name = 'aboutus/registration.html'
authentication_form = LoginForm
class MyLogoutView(LogoutView):
template_name = 'aboutus/logout.html'
@method_decorator(login_required(login_url='/about/registration/'), name='dispatch')
class UserMyAccounts(TemplateView):
def get(self, request, *args, **kwargs):
return super().get(request, *args, **kwargs)
template_name = 'aboutus/myaccounts.html'
def sign_up(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
un = form.cleaned_data['username']
pword = make_password(form.cleaned_data['password'])
fname = form.cleaned_data['first_name']
lname = form.cleaned_data['last_name']
em = form.cleaned_data['email']
compname = form.cleaned_data['company_name']
job = form.cleaned_data['job']
mobno = form.cleaned_data['mobile_no']
country = form.cleaned_data['country']
state = form.cleaned_data['state']
sign_up_prop = SignUpModel(first_name=fname, last_name=lname,
username=un, password=pword, email=em,
company_name=compname, job=job, mobile_no=mobno, country=country, state=state)
sign_up_prop.save()
"""username and password from request"""
un_request = request.POST.get('username')
pass_request = request.POST.get('password')
authen = authenticate(
request, username=un_request, password=pass_request)
if authen is not None:
login(request, authen)
return HttpResponseRedirect('/about/myaccounts/')
else:
form = SignUpForm()
return render(request, 'aboutus/sign-up.html', {'form': form})
urls.py
from django import views
from django.urls import path
from about import views
from django.contrib.auth import views as auth_views
from django.views.generic.base import TemplateView
from .forms import LoginForm
urlpatterns = [
path('', views.about_first_page, name='about_first_page'),
path('pricing', views.pricing, name='pricing'),
path('registration/', views.MyLoginView.as_view(), name='login'),
path('logout/', views.MyLogoutView.as_view(), name='logout'),
path('sign-up/', views.sign_up, name='sign-up'),
path('myaccounts/', views.UserMyAccounts.as_view(), name='myaccounts')
]
上面与function基于视图，它工作正常，但我什么时候开始这样做class基于观点，我在这一点上陷入了困境：
所有其他files是一样的。
This is views.py with class基于视图：
class SignUpView(CreateView):
form_class = SignUpForm
template_name = 'aboutus/sign-up.html'
success_url = '/about/myaccounts/'
那么，我怎样才能做同样的事情class based?
