我有一个 Ruby on rails 源代码,现在我想解析数据并发送数据。在我的代码中,它将从用户那里获取名称并显示它,如何解析 ROR 中的数据。
这是我的 controller.rb 代码
def index
@hotels = Hotel.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @hotels }
end
end
# GET /hotels/1
# GET /hotels/1.json
def show
@hotel = Hotel.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @hotel }
end
end
# GET /hotels/new
# GET /hotels/new.json
def new
@hotel = Hotel.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @hotel }
end
end
# GET /hotels/1/edit
def edit
@hotel = Hotel.find(params[:id])
end
# POST /hotels
# POST /hotels.json
def create
@hotel = Hotel.new(params[:hotel])
respond_to do |format|
if @hotel.save
format.html { redirect_to @hotel, notice: 'Hotel was successfully created.' }
format.json { render json: @hotel, status: :created, location: @hotel }
else
format.html { render action: "new" }
format.json { render json: @hotel.errors, status: :unprocessable_entity }
end
end
end
# PUT /hotels/1
# PUT /hotels/1.json
def update
@hotel = Hotel.find(params[:id])
respond_to do |format|
if @hotel.update_attributes(params[:hotel])
format.html { redirect_to @hotel, notice: 'Hotel was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @hotel.errors, status: :unprocessable_entity }
end
end
end
# DELETE /hotels/1
# DELETE /hotels/1.json
def destroy
@hotel = Hotel.find(params[:id])
@hotel.destroy
respond_to do |format|
format.html { redirect_to hotels_url }
format.json { head :no_content }
end
end
如何使用 Json 解析 ROR 中 的这些数据 如何为这些数据编写解析 json 文件,如何做到这一点
