jquery - 如何从 rails 中的 Controller 调用方法？

Question

如何从我的 r_holidays_controller 调用方法？

这是我编写脚本的尝试，但它行不通。

$(function () {
        $('#toright').click(function () {
            var sel = document.getElementById("left");
            var len = sel.options.length;
            var w_id = this.getAttribute('w_id');
            for (var i = 0; i < len; i++) 
                {
                if(sel.options[i].selected) 
                    {
                    $.ajax("/r_holidays/w_destroy", {holiday_id: sel.options[i].value, group_id: w_id}).done(function(data){});
                    }
                }
            history.go(0);
        })
      });

我想，我的 $.ajax( ... ) 一定有错误。

所以有人有想法让这个工作吗？检查我的路径时，我意识到我的路径没有列出...

r_holidays_path      GET     /r_holidays(.:format)           r_holidays#index
                     POST    /r_holidays(.:format)           r_holidays#create
new_r_holiday_path   GET     /r_holidays/new(.:format)   r_holidays#new
edit_r_holiday_path  GET     /r_holidays/:id/edit(.:format)  r_holidays#edit
r_holiday_path       GET     /r_holidays/:id(.:format)   r_holidays#show
                     PATCH   /r_holidays/:id(.:format)       r_holidays#update
                     PUT     /r_holidays/:id(.:format)   r_holidays#update
                     DELETE  /r_holidays/:id(.:format)   r_holidays#destroy 

编辑:

这是我的 Controller 代码:

class RHolidaysController < ApplicationController
  before_action :set_r_holiday, only: [:show, :edit, :update, :destroy]

  def index
    @r_holidays = RHoliday.all
  end

  def new
    @r_holiday = RHoliday.new
  end

  def edit
  end

  def create
    render json: RHoliday.find_or_create(holiday_id: params[:holiday_id].to_s, group_id: params[:group_id].to_s) 
  end  

  def w_create
    @r_holiday = RHoliday.new(r_holiday_params)

    respond_to do |format|
      if @r_holiday.save
        format.html { redirect_to @r_holiday, notice: 'RHoliday was successfully created.' }
        format.json { render action: 'show', status: :created, location: @r_holiday }
      else
        format.html { render action: 'new' }
        format.json { render json: @r_holiday.errors, status: :unprocessable_entity }
      end
    end
  end  

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

  def destroy
    @r_holiday.destroy
    respond_to do |format|
      format.html { redirect_to holidays_url }
      format.json { head :no_content }
    end
  end

  def w_destroy
    render json: RHoliday.where(holiday_id: params[:holiday_id].to_s, group_id: params[:group_id].to_s).destroy 
  end




  private
    def set_holiday
      @r_holiday = RHoliday.find(params[:id])
    end

    def holiday_params
      params.require(:r_holiday).permit(:holiday_id, :group_id)
    end

end

我的 routes.rb 中的相关行只是 resources :r_holidays

我认为您正在使用 $.get $.ajax 的语法.

尝试用 $.get 替换你的 $.ajax。
