How to add a Lua interpreter to Sublime Text 3?

Question

Lua

I decided to write in Lua in Sublime Text 3, but wondered how to "insert" the above Lua interpreter into this text editor. More specifically, in this field:

Answer 1

If you describe the problem like that, everyone will break their heads here too.
At least throw off the links of all these models.
What is the problem specifically? You can display all queries, think? DownloadRequest.all
Can you also see the number of installs per user? (It's not clear how it works for you)
If without SQL, just map, select (actions on an array) - can you solve the problem this way? And a problem only in drawing up of optimum request?

Answer 2

and the description of the tables is not attached? And between them it would be very good to see.
and then according to your request: I have 4 (apps, users, download_requests, installs) tables, help me make a selection of them as I want, but I won’t show you the structure.

Answer 3

Your user models are not correctly linked

has_many :orders #это лучше чем download_requests 
has_many :apps, through: :order #получаем app через order

belongs_to :user #связываем юзера с заявкой
belongs_to :app #связываем приложение с заявкой

has_many :orders
has_many :users, through: :order #получаем юзеров через order
