Django Adding Placeholders To Django Built In Login Forms

I'm using django built-in login forms and i want to add placeholders to username and password. My template:

Solution 1:

save this content in forms.py

from django import forms
from django.contrib.auth.formsimportAuthenticationFormfrom django.forms.widgetsimportPasswordInput, TextInputclassCustomAuthForm(AuthenticationForm):
    username = forms.CharField(widget=TextInput(attrs={'class':'validate','placeholder': 'Email'}))
    password = forms.CharField(widget=PasswordInput(attrs={'placeholder':'Password'}))

in your main urls.py (where your login view called)

from django.contrib.auth import views as auth_views
from app.forms import CustomAuthForm

urlpatterns = [
url(r'^login/$', auth_views.login, name='login', kwargs={"authentication_form":CustomAuthForm}),
]

the extra thing that we done here is added an kwargs kwargs={"authentication_form":CustomAuthForm}

please use this for your future reference django.contrib.auth.views.LoginView and django.contrib.auth.forms.AuthenticationForm

Solution 2:

save this content in forms.py

from django import forms
from django.contrib.auth.forms import AuthenticationForm
from django.forms.widgets import PasswordInput, TextInput


classMyAuthForm(AuthenticationForm):
    classMeta:
        model = User
        fields = ['username','password']
    def__init__(self, *args, **kwargs):
        super(MyAuthForm, self).__init__(*args, **kwargs)
        self.fields['username'].widget = forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Username'})
        self.fields['username'].label = False
        self.fields['password'].widget = forms.PasswordInput(attrs={'class': 'form-control', 'placeholder':'Password'}) 
        self.fields['password'].label = False

and save this content in main urls.py

from users.forms importMyAuthFormurlpatterns= [
   ...
   path('', auth_views.LoginView.as_view(template_name='users/login.html', authentication_form=MyAuthForm), name='login'),
   ...
]

please refer this site: https://github.com/django/django/blob/master/django/contrib/auth/views.py

Solution 3:

Yes you can add placeholder something like this,

classLoginForm(forms.ModelForm):
    classMeta:
        model = YourModelNamewidgets= {
            'username' : forms.TextInput(attrs = {'placeholder': 'Username'}),
            'password' : forms.PasswordInput(attrs = {'placeholder': 'Password'}),
        }

I hope this will work for you.

Solution 4:

In response to your comment on the other answer. You can subclass the the Authentication form.

from django import forms
from django.contrib.auth.formsimportAuthenticationFormfrom django.forms.widgetsimportPasswordInput, TextInputclassPlaceholderAuthForm(AuthenticationForm):
    username = forms.CharField(widget=TextInput(attrs={'placeholder': 'Email'}))
    password = forms.CharField(widget=PasswordInput(attrs={'placeholder':'Password'}))

or see the other function that was put in this question. --> How can I override the django AuthenticationForm input css class?

Solution 5:

You can add another filter

@register.filter(name="add_place_holder")defadd_place_holder(field, place_holder=None):
    if place_holder == None:
        return field
    else:
        field.field.widget.attrs.update({'placeholder': place_holder})
        return field
