Question

Let’s assume I have the following three objects:

class Filing < ActiveRecord::Base
    belongs_to :company
    has_many :people , :dependent => :destroy
end

class Company < ActiveRecord::Base
    has_many :filings
end

class Person < ActiveRecord::Base
    belongs_to :filing
end

I’m attempting to make a single request that returns the filing with it’s associated company and an array containing it’s associated people. This is being used for an API request of GET filing/:id

I saw the documentation on joining tables with ActiveRecord, however when I run the following query:

Filing.joins(:people,:company)

It doesn’t appear to include the associated people or company in the result set. I’m kind of confused about why I would do a join if the associated data won’t be returned. What am I missing here? What query should I be running?

Update

As mentioned in the comments. I want to be able to generate the following output:

{ "filing" => { "filing_id" => 123, "company" => { ... }, "people" => [{"person_id" => 1}, {"person_id" => 2}] } }

Answer 1

With the help of commenters I ended up finding the answer. All that needs to be called is:

Filing.find( id , :include => [:company,:people] )
