During Mifos implementations, the financial institution may want to implement custom functionality. Example: At the time of approval of a loan, the loan amount should not exceed 5 times the sum of balances available in all the savings accounts of the customer.
Ideally this should be done using a configurable rules engine. However, if a facility is available where a technical specialist can add some Java code and hook this code to an event when the code will be executed, it will help 'extend' Mifos functionality for a specific implementation without having to modify existing Mifos Java classes. If specialists modify existing Mifos classes, then upgrading Mifos without losing these changes could be a challenge.
There could be a configuration within Mifos as follows:
ApplicableFor: Loans
Event: PreLoanApproval
Inputs: LoanAccountData, ClientData (these have to be existing Java classes from Mifos X code - objects of these)
ClassToInvoke: com.specialist.mifosx.extensions.LoanRules
MethodToInvoke: doPreApprovalChecksForLoans
If configured, then Mifos will invoke the method from the class specified when the event happens.
Meanings:
ApplicableFor - whether it is applicable for Clients, Loans, Savings etc.
Events - will be one of a predefined list. The predefined list could be as follows:
- preClientCreate / preClientUpdate / preClientClose
- preClientApprove / preClientReject
- postClientCreate / postClientUpdate / postClientClose
- postClientApprove / postClientReject
- preLoanCreate / preLoanUpdate / preClientDelete
- preLoanApprove / preLoanReject
- postLoanCreate / postLoanUpdate / postClientDelete
- postLoanApprove / postLoanReject
- Etc.
ClassToInvoke: The Java class which has the custom code to be invoked
MethodToInvoke: The Java method within the above class which has the custom code to be invoked
For the example mentioned above:
The doPreApprovalChecksForLoans method in com.specialist.mifosx.extensions.LoanRules class would take two input parameters of type LoanAccountData and ClientData. The method would internally have the logic for: fetching all savings balances for the customer and checking that the loan amount does not exceed 5 times the sum of these balances.
I think this will be the first step to integrating a rules engine eventually to various 'events' in Mifos X.
