【问题描述】:
我正在使用 RoR 制作食物成分表。当我尝试在 localhost 上查看表时,出现以下错误
:/Users/RubymineProjects/FoodDBScript/app/controllers/food_tables_controller.rb:72: 语法错误,意外的 ',' ...ID,:Food_Item,:Edible_part_%, :Water_g, :Kilojoules_kj, :K... ... ^
这是我的 food_tables_controller.rb 的一部分
class FoodTablesController < ApplicationController
before_action :set_food_table, only: [:show, :edit, :update, :destroy]
# GET /food_tables
# GET /food_tables.json
def index
if params[:food_item].nil?
@food_tables = FoodTable.all
else
@food_tables = FoodTable.where("Food Item LIKE ?", '%' + params[:food_item] + '%')
end
end
# GET /food_tables/1
# GET /food_tables/1.json
def show
end
# GET /food_tables/new
def new
@food_table = FoodTable.new
end
# GET /food_tables/1/edit
def edit
end
# POST /food_tables
# POST /food_tables.json
def create
@food_table = FoodTable.new(food_table_params)
respond_to do |format|
if @food_table.save
format.html { redirect_to @food_table, notice: 'Food table was successfully created.' }
format.json { render :show, status: :created, location: @food_table }
else
format.html { render :new }
format.json { render json: @food_table.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /food_tables/1
# PATCH/PUT /food_tables/1.json
def update
respond_to do |format|
if @food_table.update(food_table_params)
format.html { redirect_to @food_table, notice: 'Food table was successfully updated.' }
format.json { render :show, status: :ok, location: @food_table }
else
format.html { render :edit }
format.json { render json: @food_table.errors, status: :unprocessable_entity }
end
end
end
# DELETE /food_tables/1
# DELETE /food_tables/1.json
def destroy
@food_table.destroy
respond_to do |format|
format.html { redirect_to food_tables_url, notice: 'Food table was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_food_table
@food_table = FoodTable.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def food_table_params
params[:food_table]
end
end
