Personally, I would view the Receipt Summary as its own class, maybe
ReceiptRpt::ReceiptSummary. I'd probably do the work currently in your
receiptsummary method in the initialize method, then store the values that
you need in your view in instance variables, and define attr_readers for
them. Example:
class ReceiptRpt::ReceiptSummary
attr_reader :share_amt, :loan_balance
def initialize(fdate, tdate)
# ... do work and assign @share_amt, @loan_balance,
# and any other data you need access to later on
end
end
Usage:
@summary = ReceiptRpt::ReceiptSummary.new(Date.new(2016, 5, 1), Date.new(
2016, 5, 31))
@summary.share_amt #=> Share Amount
@summary.loan_balance #=> Loan Balance
