SyncableModels

This gem helps you to:

1. Fetch object attributes from the outside of your app
2. Mark objects as synced by a special tag
3. Drop this marks automatically when the object updates

Add this line to your application's Gemfile:

gem 'syncable_models'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install syncable_models

Then generate and run migration for Sync model:

$ rails syncable_models:install:migrations
$ rake db:migrate

At first you should mark you model as syncable:

class Project < ApplicationRecord
  include SyncableModels::ActiveRecord
  ...
end

Then create a controller with API methods.

class ImportApiController < ApplicationController
  include SyncableModels::Controller
  sync_for :projects
end

This code will automatically generate two api methods for this controller:

1. projects - get a list of non-synced Project objects

• receives: destination argument - the tag for syncing and an optional count parameter (default value is 50).
• returns: response with an array of the objects, non-synced by this tag

2. sync_projects - sync Project objects by a tag

• receives: ids - an array of objects' ids for syncing; destination - tag for syncing
• returns: {status: 200} if everything is Ok.

Example:

http://host.dev/import_api/projects?destination=redmine&count=50
http://host.dev/import_api/sync_projects?ids[]=c4bebd13-7de4-450d-82d7-e9a575f978c7&destination=redmine
