Create a hidden field in the admin site

Question

How can I create a fully hidden field (input and label) in the admin site? I know about the exclude property, but it fully excludes the field from the template,

Answer 1

I found it quite handy to use the 'classes' attribute in fieldsets to hide fields but still leave them in a request. In your model admin you can write

fieldsets = [
        ('Visible Fields', 
         {'fields': [('name', 'comment'),]}),
        ('Collapsable Fields', 
         {'fields': [('rare_property',)],'classes': ['collapse']}),
        ('Hidden Fields', 
         {'fields': [('magic_property',)],'classes': ['hidden']}),
            ]
