将IN上的SQL转换为Active Record查询匹配

Question

How would I convert this sort of SQL into Active Record Syntax. I've struggled mainly resolving the IN with the other elements.

SELECT \\"accounts\\".* FROM account_categories, accounts WHERE \\"accounts\\".\\"worksheet_id\\" = 5 AND (account_categories.name IN ('Savings','Deposit') AND account_categories.id = accounts.account_category_id) ORDER BY \\"accounts\\".\\"id\\" ASC"

worksheet_id will vary, won't always be 5.

I want to use this in a scope in the Account model. Similar like this

scope :savings, -> { from('account_categories, accounts').where("account_categories.name = ? AND account_categories.id = zen_accounts.account_category_id", 'Savings') }

but testing for both Savings & Deposit something like this:

scope :savings_and_deposit, -> { from('account_categories, accounts').where("account_categories.name = ? AND account_categories.id = zen_accounts.account_category_id", ['Savings','Deposit]) }

Answer 1

Try this code:

scope :savings, -> (worksheet_id) { filtered_categories(worksheet_id, ['Savings']) }
scope :savings_and_deposit, -> (worksheet_id) { filtered_categories(worksheet_id, ['Savings', 'Deposit']) }

scope :filtered_categories, -> (worksheet_id, category_names) do 
  joins(:account_categories).
  where(worksheet_id: worksheet_id).
  where(account_categories: {name: category_names}).
  order(id: :asc)
end

This code supposes what Account model already has relation account_categories , otherwise replace joins(:account_categories) with joins("JOIN account_categories ON account_categories.id = accounts.account_category_id")
