python - Creating threaded comments model Django -

i have model stores comments.

class comment(timestampedmodel):     content = models.textfield(max_length=255)     likes = models.integerfield(default=0)     content_type = models.foreignkey(contenttype)     object_id = models.positiveintegerfield()     content_object = generic.genericforeignkey('content_type', 'object_id') 

however, want add in ability reply comment (threaded comments)i.e.

1 comment 1    2 reply comment 1       3 reply comment 2       4 reply comment 2         5 reply comment 4    6 reply comment 1    7 reply comment 1 

i hoping achieved adding self refereeing related field comments model i.e.

child = models.foreignkey(comment) 

but i'm unsure work , how nested replies each comment using above method.

my question is, there correct way of doing this, , how?

yeah of course can that. can find recursive elements , should use django-mptt model. nested comments of specific comments can use below functions.

class comment(mpttmodel):     parent = treeforeignkey('self', null=true, blank=true, related_name='sub_comment')     # other fields       def get_all_children(self, include_self=false):         """         gets of comment thread.         """         children_list = self._recurse_for_children(self)         if include_self:             ix = 0         else:             ix = 1         flat_list = self._flatten(children_list[ix:])         return flat_list      def _recurse_for_children(self, node):         children = []         children.append(node)         child in node.sub_comment.enabled():             if child != self                 children_list = self._recurse_for_children(child)                 children.append(children_list)         return children      def _flatten(self, l):         if type(l) != type([]): return [l]         if l == []: return l         return self._flatten(l[0]) + self._flatten(l[1:]) 

in above code, sub_comment parent field. can use such , can achieved comment threads.
