[英]Rails: Routing Error: No route matches [PATCH] “/things”
我為模型“ Things”創建了一個編輯表單，但是在提交表單時，它返回錯誤“沒有路線與[PATCH]“ / things”匹配”。 奇怪的是，錯誤的URL是http://localhost:3000/things ，但是我希望它是http://localhost:3000/things/:id ，因為我在create下寫了redirect_to @thing功能。 我只是用資源：things定義了所有Thing路由，因此應該定義更新路徑。 我究竟做錯了什么？
Things_controller：
class ThingsController < ApplicationController
def show
@thing = Thing.find(params[:id])
@category_things = CategoryThing.all
@thing.categories.build
@thing.things.build
@related_things = RelatedThing.all
end
def index
end
def new
@thing = Thing.new
@things = Thing.all
end
def create
@thing = Thing.new(thing_params)
if @thing.save
redirect_to @thing
else
render 'new'
end
end
def edit
@thing = Thing.find(params[:id])
end
def update
@thing = Thing.find(params[:id])
if @thing.update_attributes(thing_params)
flash[:success] = "Thing updated"
redirect_to @thing
else
render 'edit'
end
end
private
def thing_params
params.require(:thing).permit(:name, :image_path, :avatar)
end
end
Things / edit.html.erb：
<h1>Edit <%= @thing.name %></h1>
<p>
<%= form_for @thing, :url => things_path, :html => { :multipart => true } do |f| %>
<%= f.text_field :name, :placeholder => "Name of the thing" %>
<br>
<%= f.label :categories_the_thing_belongs_to %>
<%= f.collection_select :categories, Category.all, :id, :name %>
<br>
<%= f.label :related_things %>
<%= f.collection_select :related_things, Thing.all, :id, :name %>
<br>
<%= f.label :display_picture %>
<%= f.file_field :avatar %>
<br>
<%= f.submit "Submit", class: "btn btn-primary" %>
<% end %>
</p>

只需刪除:url => things_path並使用：
<%= form_for @thing, :html => { :multipart => true } do |f| %>
如果使用ressourcefull路由，則form_for幫助程序會自動生成正確的resfull端點。 取決於@thing被persisted? 或new_record? 端點將是：create或：update
