【问题描述】:
我正在开发一个可以存储供应商详细信息以及纬度/经度信息的应用程序。为了使其具有地理编码能力,我在 postgis 上使用了 geocoder gem。我遵循了地理编码器的完整文档。但是,在创建任何新供应商时,我收到以下错误
NoMethodError in VendorsController#create
undefined method `address=' for #<Vendor:0x007faca1729a20> Did you
mean?addressline2=
我的 rails vendor_controller.rb
class VendorsController < ApplicationController
before_action :set_vendor, only: [:show, :edit, :update, :destroy]
def index
@vendors = Vendor.all.limit(20)
end
def new
@vendor = Vendor.new
end
def create
@vendor = Vendor.new(vendor_params)
respond_to do |format|
if @vendor.save
format.html { redirect_to @vendor, notice: 'Vendor was
successfully created.' }
format.json { render :show, status: :created, location: @vendor }
else
format.html { render :new }
format.json { render json: @vendor.errors, status:
:unprocessable_entity }
end
end
end
def update
respond_to do |format|
if @vendor.update(vendor_params)
format.html { redirect_to @vendor, notice: 'Vendor was
successfully
updated.' }
format.json { render :show, status: :ok, location: @vendor }
else
format.html { render :edit }
format.json { render json: @vendor.errors, status:
:unprocessable_entity }
end
end
end
private
def set_vendor
@vendor = Vendor.find(params[:id])
end
def vendor_params
params.require(:vendor).permit(:name, :email, :phone_no, :addressline1,
:addressline2, :landmark,
:city, :state, :country, :pincode, :latitude, :longitude, :status)
end
end
我的 vendor.rb
class Vendor < ActiveRecord::Base
has_many :vendor_products
has_many :products, through: :vendor_products
geocoded_by :full_path
after_validation :geocode
reverse_geocoded_by :latitude, :longitude
after_validation :reverse_geocode
def full_path
[addressline1, addressline2, landmark, city, state, country,
pincode].compact.join(', ')
end
end
我的供应商架构
create_table "vendors", force: :cascade do |t|
t.string "name"
t.string "email"
t.string "phone_no"
t.string "addressline1"
t.string "addressline2"
t.string "landmark"
t.string "city"
t.string "state"
t.string "country"
t.float "latitude"
t.float "longitude"
t.boolean "status"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "pincode"
end
我在代码中的任何地方都没有使用地址字段。然而,每当我尝试从控制台和表单创建新供应商时,它都会抛出这个错误。我已经尝试重新启动服务器,这是一次徒劳的尝试。我是 Rails 新手,非常感谢您对详细描述的帮助。如果您需要更多信息,请告诉我

您可以尝试将“full_path”方法重命名为“address”
