USAGE

Django admin site

Apply summernote to all TextField in model

In admin.py,

from django_summernote.admin import SummernoteModelAdmin
from .models import SomeModel

# Apply summernote to all TextField in model.
class SomeModelAdmin(SummernoteModelAdmin):  # instead of ModelAdmin
    summernote_fields = '__all__'

admin.site.register(SomeModel, SomeModelAdmin)

Apply summernote to not all TextField in model

Although Post model has several TextField, only content field will have SummernoteWidget.

In admin.py,

from django_summernote.admin import SummernoteModelAdmin
from .models import Post

class PostAdmin(SummernoteModelAdmin):
    summernote_fields = ('content',)

admin.site.register(Post, PostAdmin)

Form

In forms,

from django_summernote.widgets import SummernoteWidget, SummernoteInplaceWidget

# Apply summernote to specific fields.
class SomeForm(forms.Form):
    foo = forms.CharField(widget=SummernoteWidget())  # instead of forms.Textarea

# If you don't like <iframe>, then use inplace widget
# Or if you're using django-crispy-forms, please use this.
class AnotherForm(forms.Form):
    bar = forms.CharField(widget=SummernoteInplaceWidget())

And for ModelForm,

class FormFromSomeModel(forms.ModelForm):
    class Meta:
        model = SomeModel
        widgets = {
            'foo': SummernoteWidget(),
            'bar': SummernoteInplaceWidget(),
        }

Last, please don't forget to use safe templatetag while displaying in templates.

{{ foobar|safe }}
