http://stackoverflow.com/questions/17118320/how-to-add-readonly-inline-on-django-admin
After a while of trying to find the name I figured out thanks to this answer, so I checked the names at self.opts.local_fields and found the name of the middle table and added it to a readonly field:
class SummaryInline(admin.TabularInline):
model = ParserError.summaries.through
readonly_fields = ('myclasssummary',)
pretty simple but took me a while so I figured out it was a good idea to add it here.
这个是否是你想要问的？
