Question

Consider the following, I have a Job class that has inputs and one output. I have the following in my job.rb

  def as_json(options={})
    super(include: [:inputs,:output])
  end

So this has been working very well and my JobController has been dolling out well formatted and useful JSON responses.

I am working on a way to display a version of the Job JSON to the user that only showed the inputs, so I did the following and got some weird behavior:

@job.to_json(include: [:inputs])

This method ignores the options passed to it, and calls the as_json method on the model

So my question is, once you have defined as_json, how do you get a different json view of the object?

Thanks!

Answer 1

You could try this to pass output and inputs by default :

def as_json( options = { :include => {:inputs, :output} } )
   super(options)
end

then you can pass your options for special cases :

@job.as_json( :include => {:inputs} )
