django请求问题，从bd获取用户

Question

SO，我想从数据库中获取用户详细信息，并将其显示在user.html中，但我做不到。它们不会显示在这个文件中。我尝试创建类UserView(ListView(：，但它不起作用。也许我不理解这个请求。

view.py

def registerform(request): ##registerform 
form = SightUp(request.POST or None)
if form.is_valid():
user_obj = form.save()#Сохранение значений в датабазе методом .save()
username = form.cleaned_data.get('username')
raw_password = form.cleaned_data.get('password1')
email = form.cleaned_data.get('email')
user = authenticate(username=username,password =raw_password,email=email)
login(request,user)
return redirect('/userprofile/')# ЗАМЕНИТЬ
context =  {'form':form }
return render(request,'user.html',context)

#def userprofiles(request):
#  userall = detailsuser.objects.all()
#  context = {
#      'objects':userall
#  }
# return render(request,'userprofile.html', context)
class UserView(ListView):
model = User
template_name = 'userprofile.html'
context = 'detailsuser'
def get_queryset(self):
return detailsuser.objects.filter(user = self.request.user)

forms.py

class SightUp(UserCreationForm):
first_name = forms.CharField( widget = forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'First Name'}), max_length=32, help_text='First name')
last_name = forms.CharField( widget = forms.TextInput(attrs={'class':'form-control','placeholder':'Last name'}), max_length=32)
email = forms.EmailField(widget =forms.TextInput(attrs={'class':'form-control', 'placeholder': 'Email'}), max_length =64,help_text='Enter valid Email')
username = forms.CharField(widget =forms.TextInput(attrs={'class':'form-control','placeholder':'Username'}))
password1 = forms.CharField(widget =forms.PasswordInput(attrs={'class':'form-control','placeholder':'Password1'}))
password2 = forms.CharField(widget =forms.PasswordInput(attrs={'class':'form-control','placeholder':'Password2'}))
class Meta(UserCreationForm.Meta):
model = User
fields = UserCreationForm.Meta.fields + ('first_name','last_name','email')

user.html

{% for i in detailsuser %}
<h1> yourname: i.email </h1>
{% endfor %}
<h1>Your last name:</h1>
<h1>Your nickname:</h1>

型号.py

class detailsuser(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)

Answer 1

您的挑战源于寄存器视图，您需要对POST方法进行条件测试，如下所示：

def registerform(request): ##registerform 
if request.method == 'POST': #Here is where you make the condition for POST
form = SightUp(request.POST or None)
if form.is_valid():
user_obj = form.save()#Сохранение значений в датабазе методом .save()
username = form.cleaned_data.get('username')
raw_password = form.cleaned_data.get('password1')
email = form.cleaned_data.get('email')
user = authenticate(username=username,password =raw_password,email=email)
login(request,user)
return redirect('/userprofile/')# ЗАМЕНИТЬ
else:
form = SightUp()
context =  {'form':form }
return render(request,'user.html',context)

您的用户html出现问题，您没有添加｛%endfor%｝标记，这就是您看不到任何信息的原因。这样做：

{% for i in detailsuser %}
<h1> yourname: i.email </h1>
{% endfor %}
<h1>Your last name:</h1>
<h1>Your nickname:</h1>
{% endfor %}

我回答了它。问题是因为我的模板中的循环
