Ruby on Rails
Monday, April 23, 2018
If you read the Rails Guides you will find much useful information. However I suggest that first you work right through a good tutorial such as railstutorial.org (which is free to use online) which will show you the basics of Rails. Then you will be able to answer such questions yourself.

Table: finance_fee_particulars
Fields: id,finance_fee_category_id,student_category_id,admission_ no,batch_id, due_date
Model: Batch
Table: batches
Fields: id, name
Relationships:

#
has_many :fee_particulars, :class_name => "FinanceFeeParticular"
has_many :fee_discounts
has_many :batches,:through=>:category_batches
has_many :category_batches
class FinanceFeeParticular < ActiveRecord::Base
belongs_to :finance_fee_category
belongs_to :student_category
belongs_to :receiver,:polymorphic=>true
belongs_to :batch
has_many :fee_discounts
class Batch < ActiveRecord::Base

and the need a Query to get all the Students admission_no
based the Due_date if less the Currenct Date for Each the Particular I select from drop down.
