nested array in strong parameters

Question

I have inputs which get loaded over ajax and get's inserted in a other form with javascript with this fields:

<input name="project[config][service][3][web][auth]" type="checkbox">

and two other inputs with:

<input type="text" name="project[config][service][3][web][user]">
<input type="text" name="project[config][service][3][web][pass]">

how can I permit this to the controller to accept the values?

I tried it with these:

params.require(:project).permit(
        :title,
        :description,
        config: [
            service: {
                [] => [
                    :domains,
                    web: [
                        :auth,
                        :user,
                        :pass
                    ]
                ]
            }
        ],
        documents: []
      )

but it didn't worked. In the console i have this as project_params[:config]

{"service"=><ActionController::Parameters {"3"=><ActionController::Parameters {} permitted: true>} permitted: true>}

the params[:project][:config] looks like this:

{
  "service" => { 
    "3" => {
      "web" => {
        "auth"=>"on",
        "user"=>"asdasdasdasda",
        "pass"=>"asdasdasd"
      }
    }
  }
}

Try it this way, it should work:

params.require(:project).permit(
       :title, 
       :description, 
       config: {
         service: [
           :domains,
           web: [:auth, :user, :pass]
         ]
       },
       documents: []
     )

@Evolutio problem is on the part of service: { [] => [ definition. The hash you've added when the key is an empty array. You don't have to do that. Rails recognise an array by numbers in the keys and do the array processing for you.
