Making a nested params for xxx_tag of View Helper in Rails

🤔 Situation

Want to make like this params that have Hash inside an Array at the award_content.
​

[1] pry> params
=> {"utf8"=>"✓",
 "books"=>
  {"author_name"=>"Minato",
   "book_name"=>"HELLO",
   "category"=>"Fiction",
   "awards"=>[{"award_id"=>"1", "award_title"=>"new", "award_content"=>"award for new people"},
              {"award_id"=>"2", "award_title"=>"movie", "award_content"=>"it becames to movie"}
             ]},
 "action"=>"create",
 "controller"=>"books"}

​

🦄 How to do it?

👍 in erb

<%= hidden_field_tag 'books[awards][][award_id]', award.id %>
<%= hidden_field_tag 'books[awards][][award_title]', award.title %>
<%= hidden_field_tag 'books[awards][][award_content]', award.content %>

​

👍 in model

Turn accept nested attribuetes.
​

  has_many :awards

  validates_precence_of :awards
end
