Handling nested attributes (hash of hashes) #531
Description
Hello! I am wondering how I can set up my interaction to expect has_many nested attributes in the Rails form format.
I have two classes:
class User
has_many :pets
end
class Pet
belongs_to :user
end
And when a create a form for the User model and I want to already create their pets, I can just use the fields_for helper to send a pets_attributes hash with others hash (simulating an array).
Example:
The submit will be sent in this format:
"user" => { "pets_attributes"=>{"0"=>{"name"=>"Faisca}, "1" => {"name" => "Cat"}}}
I would like to know how to expect the pets_attributes hash inside of my interaction, knowing that the pets_attributes can have n hashes because it is a has_many association.
