Rails：如何将 gem 的类保存为我的数据库中的模型？

Question

I've been building a Google Tasks integration app and just switched to using the Google API Client ( gem 'google-api-client', '~> 0.34' )

This gives me some classes that I'm really starting to like:

Google::Apis::TasksV1::Task
Google::Apis::TasksV1::TaskList
Google::Apis::TasksV1::Tasks # (for multiple records)
Google::Apis::TasksV1::TaskLists # (for multiple records)

These classes come with all the attributes I want and I'm thinking it would be nice to actually have these records in my database instead of what I'm doing now, which is HTTP requests with OAuth (using methods provided by the gem)

With their gem integrated into a custom class, I can do things like:

> ts = TaskService.new(user)
=> #<TasksService:0x00007f973be03bc8 @user=#<User #userstuff>, @service=#<Google::Apis::TasksV1::TasksService:0x00007f973be03b28 @root_url="https://www.googleapis.com/", @base_path="tasks/v1/", @upload_path="upload/tasks/v1/", @batch_path="batch/tasks/v1", @client_options=#<struct Google::Apis::ClientOptions #morestuff>, @request_options=#<struct Google::Apis::RequestOptions authorization=#<Signet::OAuth2::Client:0x00007f973be02020 @authorization_uri=#<Addressable::URI:0x3fcb9df05304 URI:https://accounts.google.com/o/oauth2/auth>, @token_credential_uri=#<Addressable::URI:0x3fcb9db99f08 URI:https://accounts.google.com/o/oauth2/token>, @client_id="secret", @client_secret="secret", @code=nil, @expires_at=nil, @issued_at=nil, @issuer=nil, @password=nil, @principal=nil, @redirect_uri=nil, @scope=nil, @state=nil, @username=nil, @access_type=:offline, @expiry=60, @extension_parameters={}, @additional_parameters={}, @access_token="secret", @id_token=nil>, retries=0, header=nil, normalize_unicode=false, skip_serialization=false, skip_deserialization=false, api_format_version=nil, use_opencensus=true>>>

> ts.service.list_tasklists

The items come back as structured classes! It's great!

However, there's a good amount of latency with every call.

I'm running these commands in jobs, but I'm also thinking about saving these to my database (postgresql) and just comparing updated timestamps instead of pulling the information every single time I need it.

So, here's my question:

How can I take the class as-is and make it a model in my database?

I want to be able to call Google::Apis::TasksV1::Task.create(tasklist_attrs) and other such model-type methods.

I have noticed that they don't respond exactly like my own classes (that inherit from ActiveRecord::Base ):

2.6.3 :008 > User.new
 => #<User id: nil, name: nil, title: nil, phone: nil, admin: false, staff: false, client: false, volunteer: false, contractor: false, email: "", oauth_provider: nil, oauth_id: nil, oauth_image_link: nil, oauth_token: nil, oauth_refresh_token: nil, oauth_expires_at: nil, created_at: nil, updated_at: nil, discarded_at: nil>

2.6.3 :009 > Google::Apis::TasksV1::Task.new
 => #<Google::Apis::TasksV1::Task:0x00007f973e2d8908> # no nil attributes by default?

Seems to me like what you need here is caching:

Pseudo-code, please adjust to your case, but something like this would do:

ts = TaskService.new(user)
tasklist = Rails.cache.fetch("list-tasklists-#{user.id}", expires_in: 2.hours) do
  ts.service.list_tasklists
end

You can then write a cache invalidator hooked to the API and possibly a cache hot reloader, so your user's cache is always there.

Edit:
I know this is not what you asked for, but it might be a solution, looking at your use case.
