ruby - Rails 4 strong params formatting with multiple keys -

-

i working service takes in number of custom attributes , serializes hash.

so this:

 custom_contacts: {"address_book"=>    [{"contact_list"=>"user_data",      "contacts"=>[{"name"=>"user_data", "number"=>"user_data"},                           {"name"=>"user_data", "number"=>"user_data"},                           {"name"=>"user_data", "number"=>"user_data"}]}]}

the issue can't quite seem play nicely strong params in rails. i've read documentation here , can't seem wrap head around how set up.

you may need 1 "permit" blow.

a = actioncontroller::parameters.new(     {"data_key"=>        [{"name_key"=>"user_data",          "organization_key"=>[{"key1"=>"user_data", "key2"=>"user_data"},                               {"key3"=>"user_data", "key4"=>"user_data"},                               {"key5"=>"user_data", "key6"=>"user_data"}]}]}     )      a.permit(data_key: [:name_key, organization_key: [:key1, :key2, :key3, :key4, :key5, :key6]])
