Rails as_json with conditions












2















In my application, :foos have many :bars, and I'm serializing each foo as JSON like so:



@foo.as_json(
except: [:created_at, :updated_at],
include: {
bars: { only: [:ip_addr, :active] }
}
)


This gives me the following:



{
"id" => 2,
"name" => "Hello World",
"bars" => [
{ "ip_addr" => "192.123.12.32", "active" => 0 },
{ "ip_addr" => "192.123.12.33", "active" => 1 }
]
}


As you can see, my serialized hash includes an inactive bar. How can I exclude inactive bars from my hash?



It would be great if I could do this:



include: { bars: { only: { :active => true }}}


Have I taken as_json as far as it will go? Do I need to switch to active model serializers now?

          I think you could try add some method like active_bars which will return exactly what you need like:



          def active_bars
          bars.where active: true
          end


          or you could even add new relation:



          has_many :active_bars, -> { where active: true }, class_name: '..', foreign_id: '..'


          and then you will be able write:



          @foo.as_json(
          except: [:created_at, :updated_at],
          include: {
          active_bars: { only: [:ip_addr, :active] }
          }
          )

            you use as_json with conditions for customize json response for some actions, but model serializers for default json response that you needed for the most responses.



            Read these Model_Serializer VS. as_json, record-serializers-from-scratch.
