Когато текущият потребител създаде публикация, иска да знае местоположението на потребителя чрез метода за обръщане на IP в Geo-coder. За това създадох модел на публикация, потребител и местоположение. Преминах през railscasts и се научих да инсталирам Geocoder и мога да намеря географска ширина, дължина чрез адрес. Сега как да интегрирате потребителски идентификатор от устройство към геокодер, за да определите текущото потребителско местоположение.
class Location < ActiveRecord::Base
belongs_to :user
geocoded_by :address
after_validation :geocode, :if => :address_changed?
end
class LocationsController < ApplicationController
before_action :set_location, only: [:show, :edit, :update, :destroy]
respond_to :html
def index
#location = request.location
@locations = Location.all
respond_with(@locations)
end
def show
respond_with(@location)
end
def new
@location = Location.new
respond_with(@location)
end
def edit
end
def create
if params[:location].blank?
@location = request.location
@locations = Location.near([current_user.latitude, current_user.longitude], 50, :order => :distance)
end
respond_with(@location)
