无法使用ActiveStorage将头像附加到Rails 6中的模型

Question

我在试着把一个头像附加到一个侧面模型上。我有rails 5.2应用程序，并更新到rails 6。这是上传头像的表单。

​

在配置中，我需要活动存储引擎require_relative 'boot‘

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "active_storage/engine"

# require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

module ArtsySpace
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1
    # Use Vips for processing variants.
    config.active_storage.variant_processor = :vips
    # Use ActiveStorage for file storage
    config.active_storage.service
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.
  end
end

当我查找配置文件avatar时，我可以在控制台中看到它。但是当我检查是否附加时，它返回false。

2.5.0 :004 > Profile.first.avatar.methods
  Profile Load (0.4ms)  SELECT "profiles".* FROM "profiles" ORDER BY "profiles"."id" ASC LIMIT $1  [["LIMIT", 1]]

如何将图像附加到配置文件头像？

Answer 1

我在生产中有以下内容，但在开发中没有，这是导致问题的原因。

config.active_storage.service = :local
