Ruby on Rails

Pradeep, following pertains to more advanced folks here.  I thought that demonstrating a good solution would be easy, but I am encountering LocalJumpError: no block given (yield) on transaction_id... I created a transaction table, and referenced it from User has_many.  Folks, what the problem there?

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.
As per my understanding I have set it up as follows

    User has_many :expenses, through: :transactions
    User has_many :incomes, through: :transactions
   
    Expense belongs_to :user
   
    Income belongs_to :user

Here I am not sure what the transaction would associate and also expene/income type.

Any suggestions/insights would be great.
