Rails通过关联删除has_many

Question

我有 has_many 通过与用户、附件和表单模型的关联，我只想删除关联，而不是附件。我写了名为 "sil"

的删除方法

user.rb

  has_many :forms
  has_many :attachments, through: :forms

attachment.rb

has_many :forms
has_many :users, through: :forms

form.rb

 belongs_to :user
 belongs_to :attachment

sil method

def sil # remove the product from user
 @user = User.find(params[:id])
 attachment = Attachment.find(params[:attachid])
 @user.attachments.delete(attachment)
 redirect_to user_path(@user.id)
end

view

<%= button_to "Sil",attach ,method: "delete",:controller => "attachments", :action => "sil" , :attachid =>attach.id %>

我有附件的资源路由，我有附件的 destroy 方法来删除元素。我需要 sil 方法的查看和路由帮助

Answer 1

试试这个：

resources :attachments do
  member do
    delete 'sil'
  end
end

这样的路由助手：

sil_attachment_path(id: attachmentid, user_id: userid)
