Answer 1

您可以这样做：

<%= link_to "Edit",  edit_text_post_path(text_post) %>

Answer 2

由于您在routes.rb中使用资源（根据您提供的路线）。如果你想进入编辑页面，最好使用路径助手，记得在参数中提供你想要编辑的text_post：

<%= link_to "Edit", edit_text_post_path(text_post) %>

<%= link_to "Delete", text_post_path(text_post), :method => :delete %>

你写的方式就是你在routes.rb中有一些东西定义如下：

match ':controller(/:action(/:id(.:format)))', :via => :all

即便如此，你仍然必须给它想要编辑的text_post，因为它需要在url的末尾有一个id。所以应该是这样的：

<%= link_to 'Edit', :controller => 'text_posts', :action => 'edit', :id => text_post %>

<%= link_to 'Delete', :controller => 'text_posts', :action => 'destroy', :id => text_post %>

您无需将链接包装到form_tag中。

希望它有所帮助。

Answer 3

试试这个.................

<h1><%= text_post.blog %></h1>
<%= link_to "New Text Post", new_text_post_path %>
<%= link_to "Edit", edit_text_post_path(text_post) %>
<%= link_to "Delete", text_post_path(text_post), method: :delete %>

希望这对你有用。

继续没有路由匹配进行编辑。尝试使用＆＃34;编辑＆＃34;，现在：更新，但仍然没有运气
