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 only to specific 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 }}

Warning: Please mind, that the widget does not provide any escaping. If you expose the widget to external users without taking care of this, it could potentially lead to an injection vulnerability. Therefore you can use the SummernoteTextFormField or SummernoteTextField, which escape all harmful tags through mozilla's package bleach:

In forms,

from django_summernote.fields import SummernoteTextFormField, SummernoteTextField

class SomeForm(forms.Form):
    foo = SummernoteTextFormField()

And for ModelForm,

class FormForSomeModel(forms.ModelForm):
    foo = SummernoteTextField()

THEMES

django-summernote is served with Bootstrap3 by default, but you can choose other options. You can change the theme by setting SUMMERNOTE_THEME = '<theme_name>' in settings.py.

SUMMERNOTE_THEME accepts the following values:

• bs3: Bootstrap3 theme
• bs4: Bootstrap4 theme
• bs5: Bootstrap5 theme
• lite: Lite UI theme (without Bootstrap)

In settings.py

SUMMERNOTE_THEME = 'bs4'  # Show summernote with Bootstrap4

  • See them at summernote default settings
• About language/locale: Summernote i18n section

You can style the editor via widget's attributes. These adhoc styling will override settings from SUMMERNOTE_CONFIG.

    foo = forms.CharField(widget=SummernoteWidget(attrs={'summernote': {'width': '50%', 'height': '400px'}}))

You can also pass additional parameters to custom Attachment model by adding attributes to SummernoteWidget or SummernoteInplaceWidget, any attribute starting with data- will be pass to the save(...) method of custom Attachment model as **kwargs.

# Pass additional parameters to Attachment via attributes
class SomeForm(forms.Form):
    foo = forms.CharField(widget=SummernoteWidget(attrs={'data-user-id': 123456, 'data-device': 'iphone'}))
