Passing options

[Josh Cohen]

I must be missing something obvious.

How can I pass an option (say an instance variable) from a controller to a representer and use it by direct reference.

In my links section, I need the value of a controller instance variable for use in a link path.

Eg

 link :self do

      AHOST + "/proxy/#{@crm}/people/#{id}"

 end

Try this:

representer.to_json(crm: @crm)

Then, the link block will retrieve the options: https://github.com/apotonick/roar#passing-options

Ah, got it.  My problem was that I wasn't including the opts on the block.

Another related thing..

How would I use it in an if statement?

 

Eg

If @crm=="foo"

  link :self do

        AHOST + "/proxy/#{@crm}/people/#{id}"

   end

end

Do the if inside the link block, when it returns nil it's not rendered.
