Hi,
What is the proper place to put business some more complex business logic
which requires access to other Models, not only the one on which the
operation is being executed?
*Are there any open-source projects which uses a bit of business logic and
could be a good example?*
To make myself clear: all the examples of business logic I've found are
very simple ones, like *class Person *with calculated property *FullName *which
is just a getter: FirstName + " " + LastName, or calculating Person's Age
by theirs BirthDate field.
Now I need some more complex logic, for example to calculate the
*Invoice*amount based on today's
*PricingPlan* model which is separate model.
Where should I implement methods like this? Is the Repository pattern
supposed to be place for this methods?
Or is it OK to implement these methods in the class it is logically related
to, just passing the ISession instance to the method, like so:
class Invoice
{
// ...
public void CalculatePrice(ISession dbSess)
{
var pricePlan = dbSess.Get<PricingPlan>(...); //
}
}
I come from python/django background, and there's no such problem, since
the db connection/session management is hidden away from user.
Best regards
MG
