Let's say we have a class
class BankAccount < Sequel::Model do
plugin :subclasses
end
And it's subclass
class BankAccountSub < BankAccount
end
If we are going to call it's methods like
BankAccountSub.all
We are going to get all BankAccounts.
To get only BankAccountSubs (we are assuming we can BankAccountSubs should
not have `attr` attribute (=nil)
One possible solution is to override method like this (in this case we will
get all
class BankAccountSub < BankAccount
def self.all
exclude(attr: nil)
end
end
This will work fine, but overriding all of the methods is too much work and
it is always possible to miss something.
So the question is - is there any way to create Subclassed the way that all
class methods take into account this `attr`'s value?
