Remember ids in forms (with association)

Hi there,

I'm building something and I think I'm not going the Rails way with something. I have two models: 'seasons' and 'episodes'.

# Season model: has_many :episodes, :dependent => :destroy

# Episode model: belongs_to :season

# routes.rb map.resources :seasons, :has_many => :episodes map.resources :episodes

Episodes belong to seasons, so when I want to create a new episode, I use this path: new_season_episode_path(season). I create a new episode instance like this:

@season = Season.find(params[:season_id]) @episode = @season.episodes.new

Everything's going fine, untill I want to save the whole thing. The form redirects to '/episodes' (no ID). But I have to save the season_id in the episode.

@show = Show.find( season id? ) @episode = @show.episodes.create(params[:episode])

Anyone suggestions on how to save it and not use hidden fields in the form (or do I have to?)? I hope this is clear enough.

Someday, I hope to know Rails well enough that answers to questions like this just roll off the tip of my tongue (or, in this case, the tips of my fingers as I type on the keyboard). For now, the best answer I can give you is to reference the web page where I learned how to use nested routes:

I suspect that you want to use @season.episodes.build instead of @season.episodes.new, that everything might save correctly when you save @season, and that you should not be redirecting to /episodes. But I am nowhere close to being an expert, so I could be sending you off in the wrong direction.
