Ruby on Rails: Simple way to select all records of a nested model?
- by Josh Pinter
Just curious, I spent an embarrassing amount of time trying to get an array of all the records in a nested model. I just want to make sure there is not a better way.
Here is the setup:
I have three models that are nested under each other (Facilities Tags Inspections), producing code like this for routes.rb:
map.resources :facilities do |facilities|
facilities.resources :tags, :has_many => :inspections
end
I wanted to get all of the inspections for a facility and here is what my code ended up being:
def facility_inspections
@facility = Facility.find(params[:facility_id])
@inspections = []
@facility.tags.each do |tag|
tag.inspections.each do |inspection|
@inspections << inspection
end
end
end
It works but is this the best way to do this - I think it's cumbersome.
Thanks in advance.
Josh
