Question

I have a module that returns an array:

module Module1
  class Class1

    def self.get

      num << 1

      return num

    end

  end
end

But when I call it from the controller like this:

  def index

    @trans = Module1::Class1.get()

    respond_to do |format|
      format.html # index.html.erb
      format.json { render @trans }
    end
  end

Show me the following error:

'1' is not an ActiveModel-compatible object that returns a valid partial path.

But if I do in json:

  def index

    respond_to do |format|
      format.html # index.html.erb
      format.json { render Module1::Class1.get() }
    end
  end

It returns the right result, what am I doing wrong in the first example?

Answer 1

Try this

format.json { render :json => @trans }
