can't quote ActionController::Parameters

I have following index action in controller

  def index
    details = CustomerInfo.current
                          .for_user(params[:user])
                          .for_product(params[:product])
                          .for_area(params[:area])
                          .where(value: params.permit(:value))
    render(json: details)
  end

When i added permit in where i started getting the error can't quote ActionController::Parameters at render(json: details) But if i not use permit .where(value: params[:value]) it works fine.

I don't think you are using permit as it's intended to be used.

params.permit returns an instance of ActionController::Parameters, hence the error you get. See here for the code.

permit should be used to limit the attributes that can be updated through mass assignment.

Here's the relevant documentation for it: https://apidock.com/rails/ActionController/Parameters/permit http://guides.rubyonrails.org/action_controller_overview.html#strong-parameters
