NoMethodError: undefined method `created_at' for nil:NilClass
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
So I am playing around scopes in rails model.
These queries works perfectly in development environment but not production.
Here is my Fee
model from where I am triggering active-record
query to get specific invoices from StudentFeeInvoice
Model.
app/models/fee.rb
most_recent_invoice = aStudent.student_fee_invoices.invoices_except_pending_and_adjusted.order(:created_at).last
new_filter_for_invoices = aStudent.student_fee_invoices.invoices_after_specific_date(most_recent_invoice.created_at)"
app/model/student_fee_invoice.rb
scope :invoices_except_pending_and_adjusted, -> {where("status != ? AND status != ?", "Pending", "Adjusted")}
scope :invoices_after_specific_date, -> (created_date) {where('created_at > ?', created_date)}
please correct me what I am doing wrong.
Thanks in advance !

In that case you'll need something like:
new_filter_for_invoices = aStudent.student_fee_invoices.invoices_after_specific_date(most_recent_invoice ? most_recent_invoce.created_at : DateTime.now)

You avoided error & transferred date toDateTime.now
but are you sure will this date make sense for his further logic implementation ?

Actually I am using new_filter_for_invoices as a flag if its "0" I want next code of block not to be executed. so what about this new_filter_for_invoices = aStudent.student_fee_invoices.invoices_after_specific_date(most_recent_invoice.created_at)" if new_filter_for_invoices.present?
