Rails 4 中从控制器方法创建表单更新按钮的问题
Issues with Createing a form update button from a controller method in Rails 4
嘿，我正在 Rails 4 Ruby 2 中构建 CAD 应用程序。
Background:
我有一个 f.time_select 的表单域，我想用一个在现场显示的按钮替换它。按下时，我希望它更新我的调用 table 中的 unit_on_scene 列，然后将我重定向到 show.html.erb 页面。
我的按钮看起来像：
<%= link_to "On Scene", update_unit_on_scene_call_path class: 'btn btn-success btn-sm' %>
我的 routes.rb 看起来像：
resources :calls do
collection do
get 'history'
end
member do
patch :update_unit_on_scene
end
end
然后在 Rake Routes 中给了我这个 link：
update_unit_on_scene_call PATCH /calls/:id/update_unit_on_scene(.:format) calls#update_unit_on_scene
我的控制器方法如下所示：
def update_unit_on_scene
@call = Call.find(params[:id])
@call.unit_on_scene = DateTime.now
@call.save
respond_to do |format|
if @call.update(call_params)
format.html { redirect_to @call, notice: "On Scene Time Successfully Updated. - You Are Now Logged Out Of Service" }
else
format.html { render action: 'edit' }
end
end
end
我现在遇到的问题是，当我按下按钮时，出现以下错误：
No route matches [GET] "/calls/3/update_unit_on_scene"
好像在寻找另一页？？
任何帮助将不胜感激，因为我以前从未在这条路上冒险过。
谢谢。

除非指定方法，否则 link_to 助手将发出 GET 请求。
因此，您需要在 link_to:
中指定方法 (method: :patch)
<%= link_to "On Scene", update_unit_on_scene_call_path(@call), class: 'btn btn-success btn-sm', method: :patch %>
此外，将您的控制器操作更改为：
def update_unit_on_scene
@call = Call.find(params[:id])
@call.unit_on_scene = DateTime.now
respond_to do |format|
if @call.save
format.html { redirect_to @call, notice: "On Scene Time Successfully Updated. - You Are Now Logged Out Of Service" }
