模型.py

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    phone_daytime = models.CharField(max_length=50, null=True, blank=True)

class User(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    email =  models.CharField(max_length=75)
    password =  models.CharField(max_length=75)

视图.py

def profile(request):
    """"""
    registerform = UserRegisterForm(request.POST)
    createprofileform = UserCreateProfileForm(request.POST)      
    if registerform.is_valid() and createprofileform.is_valid():                
        result = registerform.save(commit=False)
        result.set_password(request.POST['password'])                                   
        result.save()
        member.user_id = user.id
        member.member_id = result.id
        member.save()                                        
        member_profile = UserProfile.objects.get(user=result.id)
        createprofileform = UserCreateProfileForm(request.POST, instance=member_profile)
                createprofileform.save()   
    return render(request,'profile.html',{'createprofileform':createprofileform,'registerform':registerform})

查看将数据保存到数据库。

模板

<tr>
   <td>First name:</td><td>{{registerform.first_name}}</td>
 </tr>
 <tr>
    <td>Last name:</td><td>{{registerform.last_name}}</td>
 </tr>
 <tr>
    <td>Daytime phone:</td><td>{{createprofile.phone_daytime}} </td>
 </tr>
 <tr>
    <td>Email:</td><td>{{registerform.email}} </td>
 </tr>
 <tr>
    <td>Password</td><td>{{registerform.password}} </td>
 </tr>

保存的姓名和电子邮件 ID 显示在模板中，如下所示，

  <td> <input type="submit" name="delete" value="{{list.0.id}}" class="delete_reporter" /></span>
<a href="{{list.0.id}}">{{list.0.first_name|title}} {{list.0.last_name}}</a></td>
 <td> {{list.0.email}} {{list.1.phone_daytime}} {{list.1.phone_mobile}}</td>

在模板中，如果我单击<a href="{{list.0.id}}">{{list.0.first_name|title}} {{list.0.last_name}}</a>表单应该以可编辑模式打开，这样如果我想进行更改，我可以更改并再次保存它。如何在 django 中执行此操作。我在<a>标签中传递 id。

如果我理解你是正确的，你想要一些可以编辑和保存的数据。您可以借助表格来实现这一点。这是一个例子：

定义你的表格：

class BasicForm(forms.Form):
    name = forms.CharField()
    age = forms.IntegerField()

然后，在您的视图中定义您的逻辑并为您的表单提供初始数据：

def update_view(request):
    initial_data = {'name': 'John', 'age': 25}
    form = BasicForm(initial_data)

    if request.method == 'POST':
          form = BasicForm(request.POST)
          if form.is_valid():
              #  Do something with passed data, for example update existing model.
              pass

    return render(request, 'template.html', {'form': form})

如果要更新数据库中的模型，可以提供如下初始数据：

from django.forms.models import model_to_dict

model = Model.objects.get(name='John')
initial_data = model_to_dict(model, exclude=['field_name'])

form = BasicForm(initial_data)

if request.method == 'POST':
      form = BasicForm(request.POST)
      if form.is_valid():
          #  Update your "John" model
          model.name = form.cleaned_data['name']
          model.age = form.cleaned_data['age']
          model.save()

查看django forms 文档。
