Geocoder不会返回类实例的坐标

Question

我正在尝试使用地理编码器gem将经纬度坐标应用于我的CoffeeShops模型，但是我无法让地理编码器返回坐标。

当我尝试使用地址保存该类的新实例时，它已成功保存到数据库，但是经度和纬度的地理编码信息均为“ nil”。

我尝试了捆绑安装。 我尝试在geocoder.rb初始化程序中添加超时 我尝试在模型中添加和删除地址验证（状态为true）

我的咖啡店型号：

class CoffeeShop < ApplicationRecord
  belongs_to :user
  has_many :reviews
  has_one :feature_set
  has_one :wifi_speed, through: :feature_sets

  validates :name, :address, presence: true
  geocoded_by :address
  after_validation :geocode, if: :will_save_change_to_address?
end

我的地址迁移文件：

class AddAddressToCoffeeShops < ActiveRecord::Migration[5.2]
  def change
    add_column :coffee_shops, :address, :string
  end
end

我的坐标迁移文件：

class AddCoordiantesToCoffeeShops < ActiveRecord::Migration[5.2]
  def change
    add_column :coffee_shops, :latitude, :float
    add_column :coffee_shops, :longitude, :float
  end
end

我的咖啡店模式：

create_table "coffee_shops", force: :cascade do |t|
    t.string "name"
    t.string "description"
    t.integer "rating"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.bigint "user_id"
    t.float "latitude"
    t.float "longitude"
    t.string "address"
    t.index ["user_id"], name: "index_coffee_shops_on_user_id"
  end

我的地理编码器初始化程序

Geocoder.configure(
  # Geocoding options
  # timeout: 3,                 # geocoding service timeout (secs)
  # lookup: :nominatim,         # name of geocoding service (symbol)
  # ip_lookup: :ipinfo_io,      # name of IP address geocoding service (symbol)
  # language: :en,              # ISO-639 language code
  # use_https: false,           # use HTTPS for lookup requests? (if supported)
  # http_proxy: nil,            # HTTP proxy server (user:pass@host:port)
  # https_proxy: nil,           # HTTPS proxy server (user:pass@host:port)
  # api_key: nil,               # API key for geocoding service
  # cache: nil,                 # cache object (must respond to #[], #[]=, and #del)
  # cache_prefix: 'geocoder:',  # prefix (string) to use for all cache keys

  # Exceptions that should not be rescued by default
  # (if you want to implement custom error handling);
  # supports SocketError and Timeout::Error
  # always_raise: [],

  # Calculation options
  units: :km,                 # :km for kilometers or :mi for miles
  # distances: :linear          # :spherical or :linear
)
