我需要表单来更新属于项目视图中的项目的任务并得到错误

No route matches [PATCH] "/projects/1/tasks/1/edit"

这是可用路线的列表

project_tasks_path   GET     /projects/:project_id/tasks(.:format)   tasks#index
                     POST    /projects/:project_id/tasks(.:format)   tasks#create
new_project_task_path    GET     /projects/:project_id/tasks/new(.:format) tasks#new
edit_project_task_path   GET     /projects/:project_id/tasks/:id/edit(.:format)  tasks#edit
project_task_path    GET     /projects/:project_id/tasks/:id(.:format)   tasks#show
                     PATCH   /projects/:project_id/tasks/:id(.:format)   tasks#update
                     PUT     /projects/:project_id/tasks/:id(.:format)   tasks#update
                     DELETE  /projects/:project_id/tasks/:id(.:format)   tasks#destroy
 projects_path   GET     /projects(.:format)     projects#index
                     POST    /projects(.:format)     projects#create
 new_project_path    GET     /projects/new(.:format)     projects#new
 edit_project_path   GET     /projects/:id/edit(.:format)    projects#edit
 project_path    GET     /projects/:id(.:format)     projects#show
                     PATCH   /projects/:id(.:format)     projects#update
                     PUT     /projects/:id(.:format)     projects#update
                     DELETE  /projects/:id(.:format)     projects#destroy
 projects_update_path    POST    /projects/update(.:format)  projects#update
 projects_add_path   POST    /projects/add(.:format)     projects#add
                     POST    /projects/:project_id/tasks/:id/edit(.:format)  tasks#edit
 root_path   GET     /   projects#index

这是查看代码

<% @projects.each do |project| %>

<%= project.name %>
<% project.tasks.each do |task| %>

  <%= task.name %></p>

  <%= form_for [task.project, task], url: edit_project_task_path(task.project, task) do |f| %>
  <%= f.label :name %>
  <%= f.text_field :name %>
  <%= f.submit "Update task" %>
  <% end %>
<% end %>
<% end %>

在表单中，您的 URL 必须是project_task_path(project_id: task.project, task)因为您想使用 PUT。这里的错误来自 Rails 搜索routes.rb. 它正在寻找一个 PUT edit_project_task_path，但你只有一个 GET。

您正在尝试将请求提交到edit路由。

相反，请尝试project_task_path(task.project, task)在您的form_for. Rails 会知道将 PATCH 请求发送到正确的路由。
