Removing help_text from Django UserCreateForm

问题

Probably a poor question, but I'm using Django's UserCreationForm (slightly modified to include email), and I would like to remove the help_text that Django automatically displays on the HTML page.

On the Register portion of my HTML page, it has the Username, Email, Password1 & Password 2 fields. But underneath Username is "Required. 30 characters or fewer. Letters, digits, and @... only." And under Password Confirmation (Password 2), it says "Enter the same password as above for verification."

How do I remove these?

#models.py
class UserCreateForm(UserCreationForm):
    email = forms.EmailField(required=True)

    def save(self, commit=True):
        user = super(UserCreateForm, self).save(commit=False)
        user.email = self.cleaned_data['email']
        if commit:
            user.save()
        return user

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")
        exclude = ('username.help_text')

#views.py
def index(request):
    r = Movie.objects.all().order_by('-pub_date')
    form = UserCreateForm()
    return render_to_response('qanda/index.html', {'latest_movie_list': r, 'form':form},     context_instance = RequestContext(request))

#index.html
<form action = "/home/register/" method = "post" id = "register">{% csrf_token %}
    <h6> Create an account </h6>
    {{ form.as_p }}
    <input type = "submit" value = "Create!">
    <input type = "hidden" name = "next" value = "{{ next|escape }}" />
</form>

You can set help_text of fields to None in __init__

from django.contrib.auth.forms import UserCreationForm
from django import forms

class UserCreateForm(UserCreationForm):
    email = forms.EmailField(required=True)

    def __init__(self, *args, **kwargs):
        super(UserCreateForm, self).__init__(*args, **kwargs)

        for fieldname in ['username', 'password1', 'password2']:
            self.fields[fieldname].help_text = None

print UserCreateForm()

output:

<tr><th><label for="id_username">Username:</label></th><td><input id="id_username" type="text" name="username" maxlength="30" /></td></tr>
<tr><th><label for="id_password1">Password:</label></th><td><input type="password" name="password1" id="id_password1" /></td></tr>
<tr><th><label for="id_password2">Password confirmation:</label></th><td><input type="password" name="password2" id="id_password2" /></td></tr>
<tr><th><label for="id_email">Email:</label></th><td><input type="text" name="email" id="id_email" /></td></tr>

If you are doing too many changes, in such cases it is better to just override the fields e.g.

class UserCreateForm(UserCreationForm):
    password2 = forms.CharField(label=_("Whatever"), widget=MyPasswordInput

but in your case my solution will work very well.

Another, cleaner option is to use help_texts dictionary in class Meta. Example:

class UserCreateForm(UserCreationForm):
    ...
    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")
        help_texts = {
            'username': None,
            'email': None,
        }

More info in here: https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/#overriding-the-default-fields

Works perfect for username and email, but doesn't work for password2. No idea why.

You can add css class to registration_form.html file like this.

<style>

.helptext{
  visibility: hidden;
}

</style>

Simple CSS solution.

<style>
     #hint_id_username, #hint_id_password1 {
         display: none;
     }
</style>

When the forms render inspect the page source code and you will see an id for each help text. Such as hint_id_username for each form field. Use the above CSS to hide the text.
