Ransack :: Search <class : School, base : Grouping <combinator : and >> : Ransack :: Search

Question

에 대해 정의되지 않은 메소드`boarding_eq '는 ransack에 이상한 오류가 있습니다. 오류가 반환됩니다.

undefined method `boarding_eq' for Ransack::Search<class: School, base: Grouping <combinator: and>>:Ransack::Search 

;

<div class="form-group col-xs-6 pull-left"> 
     <%= f.label :boarding_eq, " Boarding Facilities", class: 'search-label ' %> 
     <%= f.select :boarding_eq, options_for_select(["","Yes", "No"]), class: 'form-control col-xs-12' %>  
</div>    

그러나 다른 모든 입력에도 사용할 수 있습니다.

<div class="form-group col-xs-6 pull-left"> 
    <%= f.label :year_of_establishment_eq, " Boarding Facilities", class: 'search-label ' %> 
    <%= f.select :year_of_establishment_eq, options_for_select(["","Yes", "No"]), class: 'form-control col-xs-12' %>  
</div>      

학교 모델은 다음과 같습니다.

class School < ActiveRecord::Base 

    attr_accessible :about, :academic_level, :country, :boarding, :district_or_province, 
        :email_address, :fees, :gender, :information_technology, :number_of_students, 
        :performing_arts, :phone_number, :photo_1, :photo_2, :photo_3, :photo_4, 
        :photo_5, :physical_address, :post_address, :school_name, :sports, :town, 
        :web_address, :year_of_establishment 

    validates :about, :academic_level, :country, :boarding, :district_or_province, 
        :email_address, :gender, :information_technology, :number_of_students, 
        :performing_arts, :phone_number, :physical_address, :post_address, :school_name, 
        :sports, :town, presence: true 

    validates :email, :with => /\A[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]+\z/, uniqueness:true 

    validates :phone_number, uniqueness:true, numericality: true, length: {minimum: 12}    

    belongs_to :user 

    has_many :school_events 

    has_many :school_reviews 

    has_many :votes 

    has_one :rating 

end 

이고 모델 마이그레이션은 다음과 같습니다.

class CreateSchools < ActiveRecord::Migration 
    def change 
    create_table :schools do |t| 
     t.integer :user_id 
     t.string :school_name 
     t.integer :year_of_establishment 
     t.string :number_of_students 
     t.string :academic_level 
     t.string :phone_number 
     t.string :email_address 
     t.string :web_address 
     t.text :physical_address 
     t.integer :post_address 
     t.string :country 
     t.string :district_or_province 
     t.string :town 
     t.text :about 
     t.string :fees 
     t.string :sports 
     t.string :information_technology 
     t.string :performing_arts 
     t.string :gender 
     t.string :boarding 
     t.text :photo_1 
     t.text :photo_2 
     t.text :photo_3 
     t.text :photo_4 
     t.text :photo_5 

     t.timestamps 
    end 
    add_index :schools, [:user_id, :year_of_establishment] 
    add_index :schools, [:school_name, :number_of_students] 
    add_index :schools, [:academic_level, :country ] 
    add_index :schools, [ :district_or_province, :fees ] 
    add_index :schools, [:boarding, :gender ]      
    end 
end 

나는 학교 모델 및 학교 이전을 추가했습니다.

Answer 1

문제는 마이그레이션을 반영하여 탑승 할 때 이전 설정이 적용된 열이 유지되었다는 것입니다.
