ruby-on-rails – 路由错误没有路由匹配[PATCH]“/ locations”

尝试更新位置项后,我收到路径错误

我正在使用before_action来设置位置ID

before_action :set_location, only: [:show, :edit, :update, :destroy]

private
def set_location
  @location = Location.find(params[:id])
end

这是我的控制器
我只有更新new和删除工作的问题

def create
@location = Location.new(location_params)
respond_to do |format|
  if @location.save
    format.html { redirect_to @location, notice: 'Location was successfully created.' }
    format.json { render action: 'show', status: :created, location: @location }
  else
    format.html { render action: 'new' }
    format.json { render json: @location.errors, status: :unprocessable_entity }
  end
end

结束

def update
respond_to do |format|
  if @location.update(location_params)
    format.html { redirect_to @location, notice: 'Location was successfully updated.' }
    format.json { head :no_content }
  else
    format.html { render action: 'edit' }
    format.json { render json: @location.errors, status: :unprocessable_entity }
  end
 end
end

这是我的溃败定义的方式

Routes match in priority from top to bottom

                             DELETE  /locations/:id(.:format)    locations#destroy

不知道我是否需要添加其他东西

最佳答案
您为表单标记指定了目标URL,而不是让Rails为您选择一个.因此,您的表单不是向/ locations /:id发出PATCH请求,而是尝试为您指定的URL创建一个,该URL没有附加PATCH路由.

只需从表单标记中删除:url选项,如下所示:

<%= form_for @location, :html => { :multipart => true , :class => 'form-horizontal' } do |f| %>
