[英]Is it weird to develop in ruby on rails without using any additional gems
[英]How can I create a Rails search bar facility without using additional gems
我正在为我们的社区构建一个小型分类应用程序,使人们可以使用仅带有参数描述和图像的表格列出要出售的产品。
这两个参数都在schema.rb中
问题:
我已经将搜索栏嵌入到index.html.erb上,并且还创建了一个空白的show.html.erb。 目前,搜索栏除了看上去很漂亮之外什么也没做,
我正在努力了解如何进行搜索以询问描述参数并将结果传递到show.html.erb上。
注意:我希望show.html.erb页及其搜索结果可以使我的索引页外观精美,并无需另外安装gem即可完成此任务。
class PinsController < ApplicationController
before_action :set_pin, only: [:show, :edit, :update, :destroy]
before_action :correct_user, only: [:edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]
def index
@pins = Pin.all.order("created_at DESC").paginate(:page => params[:page], :per_page => 15)
end
def show
end
def new
@pin = current_user.pins.build
end
def edit
end
def create
@pin = current_user.pins.build(pin_params)
if @pin.save
redirect_to @pin, notice: 'Pin was successfully created.'
else
render :new
end
end
def update
if @pin.update(pin_params)
redirect_to @pin, notice: 'Pin was successfully updated.'
else
render :edit
end
end
def destroy
@pin.destroy
redirect_to pins_url
end
private
# Use callbacks to share common setup or constraints between actions.
def set_pin
@pin = Pin.find_by(id: params[:id])
end
def correct_user
@pin = current_user.pins.find_by(id: params[:id])
redirect_to pins_path, notice: "Not authorized to edit this pin" if @pin.nil?
end
# Never trust parameters from the scary internet, only allow the white list through.
def pin_params
params.require(:pin).permit(:description, :image)
end
end
将您的索引方法更改为是否具有搜索查询。
def index
if params[:query]
@results = Advert.where('lower(description) LIKE ?', '%#{params[:query].downcase}%')
else
@results = Advert.all
end
end
您还可以使用javascript创建过滤器,或者安装searchkick
gem,或者如果您需要真正简单的安装rails4-autocomplete
