루프가있는 선택 태그 생성

Question

조인 테이블로 이동하는 선택 태그 목록을 만들어야합니다. 이 루프를 만들었습니다

- @game_details.fighting_game_main_characters.each do |main_character| 
    = simple_fields_for :combo_book_combo_works do |works| 
    = main_character.name 
    = works.input :fighting_game_main_character_id, as: :hidden, 
     input_html: {value: main_character.id} 
    = works.select :test, ["Works", "Doesn't Work", "Untested"], {}, 
     selected: "Untested", class: "form-control" 

추가하면 그것이 예상대로 나타납니다. 제출을 클릭하면 조인 테이블에 쓰지 않습니다. 나는 로그를 쳐다 보면서 마지막 선택 태그가 나는 페이지 소스를 보이는

Parameters: 
{ 
    "utf8"=>"✓", 
    "combo_book_combo"=>{ 
    "combo_book_combo_characters_attributes"=> 
     {"0"=>{"fighting_game_main_character_id"=>"1"} 
    }, 
    "combo_type"=>"Combo", 
    "character_positions"=>"Ground to Ground", 
    "screen_position"=>"Midscreen", 
    "combo"=>"ô" 
    }, 
    "keyboard-select"=>"", 
    "combo_book_combo_works"=>{ 
     "fighting_game_main_character_id"=>"13", 
     "test"=>"Works"}, 
    "commit"=>"Add combo" 
} 

제출 PARAMS 있다는보고 선택 모두 내가

id: "combo_book_combo_works_#{main_character.id}" 

를 추가하므로 동일한 ID를 가지고 것을보고

그러나 여전히 조인 테이블을 작성하지 않은으로 그 문제가 해결되지 않았다 그래서 나는 모델

class ComboBookCombo < ApplicationRecord 

    has_many :combo_book_combo_characters 
    has_many :fighting_game_main_characters, through: :combo_book_combo_characters 

    has_many :combo_book_combo_assists 
    has_many :fighting_game_assist_characters, through: :combo_book_combo_assists 

    has_many :combo_book_combo_character_extras 
    has_many :fighting_game_main_character_extras, through: :combo_book_combo_character_extras 

    has_many :combo_book_combo_works 
    has_many :fighting_game_main_characters, through: :combo_book_combo_works 

    has_many :combo_book_combo_extras 
    has_many :fighting_game_extras, through: :combo_book_combo_extras 

    validates :combo, :combo_type, :character_positions, :screen_position, presence: true 

    accepts_nested_attributes_for :combo_book_combo_characters, reject_if: proc { |attributes| attributes['fighting_game_main_character_id'].blank? }, allow_destroy: true 

    accepts_nested_attributes_for :combo_book_combo_assists, reject_if: proc { |attributes| attributes['fighting_game_assist_character_id'].blank? }, allow_destroy: true 

    accepts_nested_attributes_for :combo_book_combo_character_extras, reject_if: proc { |attributes| attributes['fighting_game_charater_extra_id'].blank? }, allow_destroy: true 

    accepts_nested_attributes_for :combo_book_combo_extras, reject_if: proc { |attributes| attributes['fighting_game_extra_id'].blank? }, allow_destroy: true 

    accepts_nested_attributes_for :combo_book_combo_works, reject_if: proc { |attributes| attributes['fighting_game_main_charater_id'].blank? }, allow_destroy: true 

    belongs_to :combo_book_user 
end 

class ComboBookComboWork < ApplicationRecord 
    belongs_to :combo_book_combo, optional: true 
    belongs_to :fighting_game_main_character 
end 


class FightingGameMainCharacter < ApplicationRecord 
    belongs_to :fighting_game 

    has_many :fighting_game_main_character_extras 

    has_many :combo_book_combo_characters 
    has_many :combo_book_combos, through: :combo_book_combo_characters 

    has_many :combo_book_combo_works 
    has_many :combo_book_combos, through: :combo_book_combo_works 

end 

다음 컨트롤러 보았다

,536,913,632

def create 
    @combo_book_combo = current_combo_book_user.combo_book_combos.build(combo_book_combo_params) 
    if @combo_book_combo.save 
     render 'index', notice: "Successfully created combo" 
    else 
     render 'index', notice: "Error creating combo" 
    end 
end 

(10)과 필요한 PARAMS

def combo_book_combo_params 
    params.require(:combo_book_combo).permit(
    :fighting_game_main_character_id, 
    :combo, 
    :combo_type, 
    :character_positions, 
    :combo_type, 
    :screen_position, 
    combo_book_combo_assists_attributes: [:id, :fighting_game_assist_character_id, :combo_book_combo_id, :_destroy], 
    combo_book_combo_character_extras_attributes: [:id, :combo_book_combo_id, :fighting_game_id, :_destroy], 
    combo_book_combo_extras_attributes:[:id, :combo_book_combo_id, :fighting_game_extra_id, :_destroy], 
    combo_book_combo_characters_attributes:[:id, :fighting_game_main_character_id, :combo_book_combo_id, :_destroy], 
    combo_book_combo_works_attributes:[:id, :combo_book_combo_id, :fighting_game_main_character_id, :test] 
) 
end 

모든 것이 그들과 함께 잘 될 것 같다하지만 난 다시 제출할 때 나는

이

상영하지 않습니다에 기록 될 그 필요에 가입 얻을 쪽으로. 루프가 생성 한 모든 선택 태그를 조인 테이블에 쓰려면 어떻게해야합니까?

Answer 1

컨트롤러는 모든 매개 변수가 combo_book_combo 값 아래의 중첩 값으로 전달 될 것으로 예상합니다.

{ 
    "combo_book_combo"=>{ 
     "combo_book_combo_characters_attributes"=>{ 
      "0"=>{"fighting_game_main_character_id"=>"1"} 
     }, 
     "combo_type"=>"Combo", 
     "character_positions"=>"Ground to Ground", 
     "screen_position"=>"Midscreen", 
     "combo"=>"ô", 
     "combo_book_combo_works_attributes"=>{ 
      "fighting_game_main_character_id"=>"13", 
      "test"=>"Works" 
     }, 
    }, 
} 

:

{ 
    "combo_book_combo"=>{ 
     "combo_book_combo_characters_attributes"=>{ 
      "0"=>{"fighting_game_main_character_id"=>"1"} 
     }, 
     "combo_type"=>"Combo", 
     "character_positions"=>"Ground to Ground", 
     "screen_position"=>"Midscreen", 
     "combo"=>"ô" 
    }, 
    "combo_book_combo_works"=>{ 
     "fighting_game_main_character_id"=>"13", 
     "test"=>"Works" 
    }, 
} 

이 컨트롤러 이 당신의 매개 변수의 모습 기대 것입니다 :

def combo_book_combo_params 
    params.require(:combo_book_combo).permit(
    :fighting_game_main_character_id, 
    :combo, :combo_type, 
    :character_positions, 
    :combo_type, 
    :screen_position, 
    combo_book_combo_assists_attributes: [ 
     :id, 
     :fighting_game_assist_character_id, 
     :combo_book_combo_id, 
     :_destroy], 
    combo_book_combo_character_extras_attributes: [ 
     :id, 
     :combo_book_combo_id, 
     :fighting_game_id, 
     :_destroy], 
    combo_book_combo_extras_attributes:[ 
     :id, 
     :combo_book_combo_id, 
     :fighting_game_extra_id, 
     :_destroy], 
    # etc 
    ) 
end 

이 당신의 매개 변수가 현재 어떤 모습인지입니다 : 즉,이 방법이해야 할 노력하고 무엇

combo_book_combo_works은 안에 있으며은 combo_book_combo 매개 변수 및 키가 combo_book_combo_works_attributes으로 변경되었습니다.

양식을 지금 보시고, 특히 combo_book_combo_characters_attributes의 비트를 살펴보십시오. 양식의 일부가 중첩 된 양식 속성으로 올바르게 구성되어있는 것 같습니다. simple_fields_for을 변경하여 독립 실행 형 뷰 도우미 메서드 호출 대신 상위 폼 (f.simple_fields_for과 같은 것)에서 호출되는 메서드로 변경해야합니다.
