Serialize array with strong_parameters

Question

I am trying to save a array using the strong_parameters gem. But I am having issues with how the form is sending my array. The params look like this:

> params[:circuit] 
=> {"title"=>"Some title", ..., "viewable_tasks"=>{"0"=>"woop", "1"=>"dee", ...}}

And my circuit_params function looks like:

def circuit_params
  params.require(:circuit).permit(:title, :id, viewable_tasks: { }, ... )
end

I can't seem to get the syntax to allow my params to work. What I get in my console is:

> circuit_params
=> {"title"=>"implement plug-and-play mindshare",
 "viewable_tasks"=>{"0"=>nil, "1"=>nil, "2"=>nil}, ...

In my model I have:

class Circuit < ActiveRecord::Base
   serialize :viewable_tasks, Array
   ...
end

I noticed that I can get it to work properly with attributes I call accepts_nested_attributes_for on, so this may have something to do with it.

Thanks for any help

Answer 1

I just had the same issue and this was the correct syntax:

def circuit_params
  params.require(:circuit).permit(:title, :id, {:viewable_tasks => []}, ... )
end
