Hi everyone,
What naming convention would you use to create associations when you use generators like this:
mix phx.gen.context Blog Post posts title body
Then you have a many-to-many with Tags
mix phx.gen.context Blog Tag tags name description
mix ecto.gen.migration create_tags_posts for the join through
Because the docs confuse me a little on best practices and clarity Ecto Association Guide – Ecto v2.2.11 especially this part EctoAssoc.Post
Do you rename the schema in TagsPosts or how do you name this relationship?
Thanks

I use plural form in alphabetical order, but it’s just by convention… You can use whatever name You want.
So in this case, I would use posts_tags.
wolfiton
So you have to create a new
Schema with changesetthat matches thismigrationorthe post and tag schemashould take care of it using the many-to-many relationship on them?kokolegorille
Following my convention, I would use
wolfiton
Thanks @kokolegorille now i think I get it because i seen code using weird convention to define this relationship and odd naming.

Sometime it makes sense to use more descriptive name…
For example, User m2m Role with a membership join table. Membership is much more descriptive than roles_users.

Sometimes but not in general, someone new can get easily confused by the naming, especially if he/she has just joined the project
