Django hide fields only in CREATE object admin page

As subject, i want to hide some fields ONLY when users enter the 'CREATE' admin page for specific model.

I know that change list_display can hide fields in admin page, but it's a global setting which will take affect not only in 'CREATE' admin page, but also in 'UPDATE' admin page.

Django now has a get_exclude method on ModelAdmin for excluding fields programmatically.

It takes the current request and the object (if any) as argument. In your case, the object argument will be none if it's a "create" page so you can use that like so:

class MyModelAdmin(admin.ModelAdmin):
    def get_exclude(self, request, obj=None):
        excluded = super().get_exclude(request, obj) or [] # get overall excluded fields

        if not obj: # if it's a create, so no object yet
            return excluded + ['extra_field_to_exclude']

        return excluded # otherwise return the default excluded fields if any

Copied from Exclude fields in Django admin for users other than superuser

def get_fieldsets(self, request, obj=None):
    fieldsets = super(MediaAdmin, self).get_fieldsets(request, obj)
    if not obj: 
        fieldsets = (
            (u'other', {
                'fields': ('media_public_id',)
            }),
        )
    return fieldsets

@admin.register(User)
class UserProfileAdmin(UserAdmin):
    def get_fields(self, request, obj=None):
        fields = super(UserProfileAdmin, self).get_fields(request, obj)
        for field in fields:
            if field == 'some_field_name' and obj is None:
                continue
            yield field
