将管理范围添加到我的路由后,我开始收到此错误:
没有路线匹配[PATCH]" / projects / 5"
提交更新或新增时会发生这种情况

我已经在接下来的帖子中尝试了一些解决方案,但没有成功:
Updating record rails 4 No route matches [PATCH] "/admin/usersupdate"
how to fix "No route matches [PATCH]"
Routing Error No route matches [PATCH] "/locations"
答案 0 :(得分:0)
您只在路线中定义了show动作,请更改此行:
resources :projects, only: [:show]
要:
resources :projects, only: [:show, :update]
或者
resources :projects
