Active Admin中突然沒有方法錯誤？

我已安裝activeadmin，並且可以正常工作以查看may app的「評論」部分，從而允許我將各個評論添加到我的業務所在的各個位置。我嘗試添加相同的設置，但使用BusinessReviews模型而不是評論（因此允許我在相同基礎上添加商業評論）Active Admin中突然沒有方法錯誤？

一切正常，直到我進入活動管理員（登錄並訪問'Business評論面板是罰款，直到我嘗試和實際添加對商家的評論，然後我得到的錯誤：

NoMethodError in Admin::BusinessReviews#new

undefined method `business_profile_image' for #<BusinessReview:0x007f893fe853d0>

我的模型如下：

class BusinessReview < ActiveRecord::Base 
belongs_to :location 
    has_many :images, :as => :referrer 
    accepts_nested_attributes_for :images, :allow_destroy => true 
    def thumbnail 
    if self.images.count > 0 
     self.images.last.avatar(:thumb) 
    else 
     nil 
    end 
    end 
end

my_app應用/管理/ business_review.rb如下：

ActiveAdmin.register BusinessReview do 
    index do 
    column :business_reviewer_name 
    column :business_review_content 
    column :business_reviewer_address 
    column :rating 
    column :location do |business_review| 
     business_review.location.name 
    end 
    column :business_profile_image do |business_review| 
     image_tag(business_review.business_profile_image) if business_review.business_profile_image.present? 
    end 
    actions 
    end 

    show do |business_review| 
    attributes_table do 
     row :business_reviewer_name 
     row :business_profile_image 
     row :business_review_content 
     row :business_reviewer_address 
     row :rating 
     row :location do 
     business_review.location.name 
     end 
    end 
    panel "Images" do 
     table_for business_review.images do 
     column {|img| img.currently_used } 
     column {|img| image_tag(img.avatar.url(:large)) } 
     end 
    end 
    active_admin_comments 
    end 

    permit_params [:id, :business_reviewer_name, :business_profile_image, :business_review_content, :business_reviewer_address, :rating, :location_id], images_attributes: [:id,:_destroy,:avatar,:usage_type, :currently_used] 

    form do |f| 
    f.inputs 'Details' do 
     f.input :business_reviewer_name 
     f.input :business_profile_image 
     f.input :business_review_content 
     f.input :business_reviewer_address 
     f.input :rating 
     f.input :location 
    end 

    f.inputs "images" do 
     f.has_many :images, :allow_destroy => true, :heading => 'Images', :new_record => true do |imgf| 
     imgf.input :currently_used 
     imgf.inputs "Attachment", :multipart => true do 
      imgf.input :avatar, :as => :file, :hint => imgf.object.avatar? \ 
      ? imgf.template.image_tag(imgf.object.avatar.url(:large)) 
      : imgf.template.content_tag(:span, "no image yet") 
     end 
     end 
    end 
    f.actions 
    end 
end

我的架構的相關部分：

create_table "business_reviews", force: true do |t| 
    t.text  "business_reviewer_content" 
    t.string "business_reviewer_name" 
    t.string "business_reviewer_address" 
    t.float "rating" 
    t.string "profile_image" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    end

的路線似乎是有好的嗎？

batch_action_admin_business_reviews POST  /admin/business_reviews/batch_action(.:format) admin/business_reviews#batch 
_action 
      admin_business_reviews GET  /admin/business_reviews(.:format)     admin/business_reviews#index 
            POST  /admin/business_reviews(.:format)     admin/business_reviews#creat 
e 
      new_admin_business_review GET  /admin/business_reviews/new(.:format)    admin/business_reviews#new 
     edit_admin_business_review GET  /admin/business_reviews/:id/edit(.:format)  admin/business_reviews#edit 
       admin_business_review GET  /admin/business_reviews/:id(.:format)    admin/business_reviews#show 
            PATCH  /admin/business_reviews/:id(.:format)    admin/business_reviews#updat 
e 
            PUT  /admin/business_reviews/:id(.:format)    admin/business_reviews#updat 
e 
            DELETE  /admin/business_reviews/:id(.:format)    admin/business_reviews#destr

我只是不（從附加給它的巡航能力不分開business_），把它作爲一個評論我完全成立的作品，是相同的。

根據您的模式沒有business_profile_image只是profile_image：

t.string "profile_image"

因此，要麼重新命名列或使用profile_image代替business_profile_image的。
