I would look into the concept of a single table inheritance for a transactions table...you'd have to add an extra attribute/column that would be 'transaction' type to indicate whether it's an expense or income, but this should be able to be done with a simple 1 to many relationship - a user has many transactions - Single Table Inheritance is great for things like this and Rails handles it very easily.

Hi,

I am building an expense tracker application and I am in middle of data modelling. I have a Users table. Each user will log his expenses with expense type and income with income type. So I need to know how can we set up associations for it.

I have User, Expense, Income and UserTransaction models.

Expense and Income will have following fields

 id, date, category, amount, description, user_id, currency

I am not sure whether I need UserTransaction table also.
But my business requirement is as follows

I should be able to get all expenses/income of a user with date range and also with category

I should also be able to get all transactions occurred with date range.
