Rails4によるscaffoldを使った基本的なCRUDを備えた複雑なフォームを作る（ブログ編）

has_manyとfields_forを使うんだろうなあと漠然と考えていましたが、Rails4で実際に実装するとどうなるでしょうか。

**

bundle exec rails generate scaffold user username:string

bundle exec rails generate scaffold post subject:string post_date:date body:text user:references

bundle exec rails generate model comment post:references subject:string handle_name:string comment:text

bundle exec rails generate model kind name:string

undefined method `link_to_remove_fields' for

accepts_nested_attributes_for :photos, :reject_if => :all_blank, :allow_destroy => true

app/assets/javascripts/application.js

function remove_fields(link) {

  $(link).prev("input[type=hidden]").val("true");

  $(link).closest(".fields").hide();

}

function add_fields(link, association, content) {

  var new_id = new Date().getTime();

  var regexp = new RegExp("new_" + association, "g")

  $(link).parent().before(content.replace(regexp, new_id));

}
