##Problem I have an eloquent model "Invoice" that hasMany "InvoiceTicket" that belongsTo "Ticket". The Ticket row contains the cost of a ticket. I am trying to write a method in Invoice to get the sum cost of all tickets in an invoice. How do I go down two nested levels to get this?
Thanks in advance for any help, Code examples are much appreciated. Jeff
##Errors
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'cost' in 'field list' (SQL: select SUM(cost) AS costs from invoice_ticket)
##Behavior Expected Expecting the sum of all cost fields.
##Actual It is looking in the InvoiceTicket relation when it needs to go to the InvoiceTicket.Ticket relation

If you want to select columns from related tables like this you have to join the tables manually - doing with() does not work for this. Also, when selecting from another table you need to add the other table in front of the column, i.e. get(['other_table.column'])
anlutro, do mean something like this?
That should work, yes. You can also replace DB::table(..)-> with Model::
How would I specify ('invoice AS i') if I switch DB::table(..)-> with Model:: ?
