Question

我正在通过活动存储将某些文件保存到本地存储。我将它们显示为页面上的链接。它们可以是pdf，图像，word文档等。我希望在其旁边有一个链接，以便能够删除单个文件，但尚未使它起作用。这是我所拥有的：

项目模型：

class Project < ApplicationRecord

belongs_to :user

has_one :proj_status, :foreign_key => "status_id", :primary_key => 'status_id'

has_many_attached :uploads

end

项目显示页面：

<%= link_to upload.filename, rails_blob_path(upload, disposition: :attachment) %>

<%= link_to 'Remove', delete_upload_project_url(upload.id), method: :delete, data: { confirm: 'Are you sure?' } %>

Projects Controller删除上传方法：

def delete_upload

attachment = ActiveStorage::Attachment.find(params[:id])

attachment.purge # or use purge_later

redirect_back(fallback_location: projects_path)

end

我得到了错误：

没有路线与[GET]“ / projects / 1 / delete_upload”匹配

我认为这是一个路由问题，但是我还无法使其正常工作。

这也是我的路线部分：

resources :projects do

  member do

  delete :delete_upload

  end

end

关于如何使它起作用的任何想法或想法？

这是我在专案专区的耙路：

DELETE /projects/:id/delete_upload/:upload_id(.:format) projects#delete_upload

projects GET /projects(.:format) projects#index

POST /projects(.:format) projects#create

new_project GET /projects/new(.:format) projects#new

edit_project GET /projects/:id/edit(.:format) projects#edit

project GET /projects/:id(.:format) projects#show

PATCH /projects/:id(.:format) projects#update

PUT /projects/:id(.:format) projects#update

DELETE /projects/:id(.:format) projects#destroy

如果有人可以帮助我，我将不胜感激！

Answer 1

您的delete_upload_project_url方法需要两个变量：一个项目和一个上载/projects/:id/delete_upload/:upload_id。您只传递上传ID。做类似delete_upload_project_url(project.id, upload.id)的事情。

Answer 2

一切从一开始就已正确设置。问题是我不小心从项目中删除了application.js的包含。在我的情况下，缺少UJS参考导致所有请求都被获取而不是删除。
