rails db indexing and through association
Hello,
Say, I have a pictures table, and there are many objects which can have
pictures, so I define a picturable type. Now, to make the query for pictures
more efficient I should index the picture table using both picturable_type and
picturable_id.
Is this the correct approach to indexing the table, or can things be done
better? I want the database retrieval operation to be extremely fast (I have
some other types such as votes, which require many queries and the speed of
query retrieval is important).
Thanks in advance fo...
