Syntax for Disabling all form fields in Django

Question

I'm trying to display a user's profile on a project. I'd like to render a form but make it disabled/unable to be changed (just displayed). I can't figure out the syntax for it. Help would be appreciated!

Here's the 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})

I essentially want to just display a readonly/disabled form. User then has an edit button that takes them to a profile edit page.

Thanks for the help!

Here's the html just in case:

 <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>

Forms.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')

do you need to enable/disable based on a button you click on your page or it remans enabled/disabled once rendered? — lmiguelvargasf, Apr 04 '19 at 00:35

Because it seems you are using django-crispy-forms, I would use the following:

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')

So when you are going to create the form, this should make it work:

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

I'm following you here, but how do I get it to be disabled in my specific view? – James Franco Apr 04 '19 at 00:54
While creating the form object with disabled fields use `user_form = UserForm(instance=request.user, disable_fields = True)` – icyfire Apr 04 '19 at 00:56
Thanks a bunch! I wish my teacher gave me more background in this but he just threw us in. – James Franco Apr 04 '19 at 00:58

Django 1.9 added the Field.disabled attribute: https://docs.djangoproject.com/en/stable/ref/forms/fields/#disabled

The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in favor of the value from the form’s initial data.

You can do this to disable the fields you want in your view:

@login_required
def profile(request):
    user_form = UserForm(instance=request.user)
    for fieldname in user_form.fields:
        user_form.fields[fieldname].disabled = True
    return render(request, 'rentadevapp/profile.html', {'user_form': user_form})

How would I do all fields? – James Franco Apr 04 '19 at 00:44
Maybe use a for loop – icyfire Apr 04 '19 at 00:47
I don't know if you intent to do this, however, the first paragraph is same as [this](https://stackoverflow.com/a/34538169) answer. – double-beep Apr 04 '19 at 15:20
