ruby on rails - Whats right way to create object (in database) from controller? -

i'm trying that:

user upload file in first controller, in conditions show page user take element file , pass file info controller in params: data#new

in data#new:

@elm_file = rails.cache.read(params[:cache_id]) @elm_id = params[:index] @user_name = params[:name] new_elm_id = elm.create_from_file @elm_file, @elm_id, @user_name if new_elm_id != 0 redirect_to :action => '', :id => new_elm_id end homecoming

in model:

new_elm = elm.new homecoming new_elm.id

the problem - nil returned. how can record new element database?

your new action of controller data returns nothing, because haven't defined behind return argument.

the 2 other lines, supposed model, returns nothing, because id field set persisted records. maybe want persist create().
