Using Symfony 4 / Doctrine 2.6. I have two entities Post and Comment. I want both to be taggable. So I create an entity Tag. I use Doctrine's class table inheritance to create the relationship:
This creates 3 tables:
tag
,post_tag
, andcomment_tag
. Thepost_tag
table structure looks like this:The
tag
table structure looks like this:How are e.g. posts and tags associated? If I want to associate post
13
with tagtest
, would the result be this:post_tag
table:tag
table:?
If so, then what if I want to associate the same tag (
test
) with a comment. Would thetag
table then look like this?That seems a bit redundant. The same entity (the
test
tag) is then represented by 2 rows in thetag
table. Am I getting this wrong?
