Я создал класс обработки исключений с именем Handler в каталоге app/exceptions. Полный путь к файлу класса: app/exceptions/handler.rb
class Handler
def initialize
end
def call(env)
request = ActionDispatch::Request.new(env)
status = request.path_info[1..-1].to_i
begin
content_type = request.formats.first
rescue Mime::Type::InvalidMimeType
content_type = Mime[:text]
end
body = { status: status, error: Rack::Utils::HTTP_STATUS_CODES.fetch(status, Rack::Utils::HTTP_STATUS_CODES[500]) }
render(status, content_type, body)
end
private
def render(status, content_type, body)
# format = "to_#{content_type.to_sym}" if content_type
# if format && body.respond_to?(format)
# render_format(status, content_type, body.public_send(format))
# else
# render_html(status)
# end
render(111, 'application/json', '{message: "Haan Bhai! Hogaya!"}')
end
def render_format(status, content_type, body)
[status, { "Content-Type" => "#{content_type}; charset=#{ActionDispatch::Response.default_charset}",
"Content-Length" => body.bytesize.to_s }, [body]]
end
def render_html(status)
path = "#{public_path}/#{status}.#{I18n.locale}.html"
path = "#{public_path}/#{status}.html" unless (found = File.exist?(path))
if found || File.exist?(path)
render_format(status, "text/html", File.read(path))
else
[404, { "X-Cascade" => "pass" }, []]
end
end
end
Внутри конфигурации Rails на config/application.rb я пытаюсь назначить его как приложение исключений.
module MyApplication
class Application < Rails::Application
# Initialize configuration defaults for originally generated Rails version.
config.load_defaults 5.2
# Settings in config/environments/* take precedence over those specified here.
# Application configuration can go into files in config/initializers
# -- all .rb files in that directory are automatically loaded after loading
# the framework and any gems in your application.
# Only loads a smaller set of middleware suitable for API only apps.
# Middleware like session, flash, cookies can be added back manually.
# Skip views, helpers and assets when generating a new resource.
config.api_only = true
config.exceptions_app = ::Exceptions::Handler.new
end
end
Это приводит к ошибке.
uninitialized constant Exceptions (NameError)
Я также пытался config.exceptions_app = Exceptions::Handler.new с похожими результатами.
Может ли кто-нибудь помочь с правильным кодом для загрузки обработчика исключений?
