Rails Adminコントローラがアクションを作成

Question

私はモデルの値を変更するための新しいアクションを作成しようとしています。

これは私のexercize.rbファイルです。

ActiveAdmin.register Exercize do 

permit_params :consegna, :libro, :spiegazione, :reviewadmin 

actions :all 

controller do 
def approve 
    exercize.reviewadmin=1 
end 
end 
action_item only: :show do |exercize| 
    link_to('New Post', approve_admin_exercize_path(exercize)) 
end 


end 

そして、これは

NoMethodError in Admin::Exercizes#show 
Showing /var/lib/gems/2.3.0/gems/activeadmin-1.0.0.pre4/app/views/active_admin/resource/show.html.arb where line #2 raised: 

undefined method `approve_admin_exercize_path' for #<ActiveAdmin::Views::ActionItems:0x007fb302ed2fa8> 
Extracted source (around line #17):

end 
action_item only: :show do |exercize| 
    link_to('New Post', approve_admin_exercize_path(exercize)) 
end 
# permit_params do 
# permitted = [:permitted, :attributes]

を生成されたエラーである私は本当にすべてのものを試してみました。 ActiveAdminのドキュメントはあまり役に立たない。これを解決する方法を教えてください。

Answer 1

ActiveAdminはパスを設定しません。あなたは依然としてあなたのレールインフラストラクチャーを設定する責任があります。

このhttps://guides.rubyonrails.org/routing.htmlは非常に詳細なリファレンスです。

エラートレースには、パス設定がないことを伝えようとしているundefined method approve_admin_exercize_pathが表示されます。 （Railsはメタプログラミングを使ってこれらのパスメソッドを構築しています）。

route.rbファイルには、これに類似するものがあります。

上記のこのコードは正確ではありません警告

resources :exercize do 
    member do 
    post :approve 
    end 
end 

。私はあなたのアプリがどのように構造化されているかわからないので、正確なコードを与えることはできません。

あなたのtermianlで、実行rake routesは利用可能なすべてのルートを表示します。
