我的報告模型has_many區域。如何在嵌套模型的控制器中使用respond_with
在我嘗試將它切換爲使用新的respond_with風格之前,areas_controller.rb工作正常。
切換後,創建和索引操作仍然正常,但編輯操作並不實際更新區域,儘管發送了「區域已成功更新」的Flash消息。爲什麼?
areas_controller.rb:
class AreasController < ApplicationController
respond_to :html
filter_resource_access
layout "wide"
def index
@report = Report.find(params[:report_id])
@areas = @report.areas
respond_with(@report, @areas)
end
def show
@report = Report.find(params[:report_id])
@area = @report.areas.find(params[:id])
respond_with(@report, @area)
end
def new
@report = Report.find(params[:report_id])
@area = @report.areas.build
respond_with(@report, @area)
end
def create
@report = Report.find(params[:report_id])
@area = @report.areas.build(params[:area])
flash[:notice] = "Area was successfully created." if @area.save
respond_with(@report, @area)
end
def edit
@report = Report.find(params[:report_id])
@area = @report.areas.find(params[:id])
respond_with(@report, @area)
#also tried leaving that respond_with out
end
def update
@report = Report.find(params[:report_id])
@area = @report.areas.find(params[:id])
flash[:notice] = "Area was successfully updated." if @area.save
respond_with(@report, @area, :location => report_area_path(@report, @area))
# also tried respond_with(@report, @area)
end
def destroy
@report = Report.find(params[:report_id])
@area = @report.areas.find(params[:id])
@area.destroy
respond_with(@report, @area)
end
end
