python - 禁用 Django 中所有表单字段的语法

Question

我正在尝试显示用户在项目中的个人资料。我想呈现一个表单，但将其禁用/无法更改(仅显示)。我不知道它的语法。帮助将不胜感激!

这是 view.py:

@login_required
def profile(request):
    user_form = UserForm(instance=request.user)
    user_form.fields.disabled = True <------- HELP HERE
    return render(request, 'rentadevapp/profile.html', {'user_form': user_form})

我基本上只想显示一个只读/禁用的表单。用户然后有一个编辑按钮，将他们带到个人资料编辑页面。

感谢您的帮助!

以下是 html 以防万一:

 <form method="GET" action="/profile_edit">{% csrf_token %}
                {{ user_form|crispy }}
                <button type="submit" class="edit btn btn-default btn-block btn-lg">Edit</button><br>
            </form>

表格.py

class UserForm(forms.ModelForm):

    password = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Repeat password', widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email')

Answer 1

因为您似乎在使用 django-crispy-forms，所以我会使用以下内容:

class UserForm(forms.ModelForm):

    password = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Repeat password', widget=forms.PasswordInput)

    def __init__(self,disable_fields=False, *args, **kwargs):
        super().__init__(*args, **kwargs)
        if disable_fields:
            self.fields['password'].disabled = True
            self.fields['password2'].disabled = True

    class Meta:
        model = User
        fields = ('username', 'first_name', 'last_name', 'email')

因此，当您要创建表单时，应该这样做:

@login_required
def profile(request):
    user_form = UserForm(instance=request.user, disable=True)
    return render(request, 'rentadevapp/profile.html', {'user_form': user_form})
