[SQLObject] _get_ function

[Samir P. <sp...@ci...>]

I need some ideas on solving this problem.

I have int field  daysOpen in my SQLObject which is not set by user.  I wrote 
a _get_daysOpen which calculates days difference between other field 
(birthday) from todays date. Now I like to calculate days difference from 
user defined date instead of today. How can I do this?

It will have to be a method, like daysOpenTo(date)

Thanks for your reply Ian. If I create it as a method than I will lose power 
of retriving data by just calling field name. Currently I solve it this way: 
When I need to pass a value to a _get_ method, I am adding a different field 
to that object and initialzing it with value I want to pass. Then in my _get_ 
method I am checking whether that object has this new field, If it has this 
new field, I use that value like a paramenter value otherwise I am using 
default value. This way I can still retrive my field data by simply calling 
field name.

Using attribute access is just a convenience, and you really shouldn't 
use it if it's not appropriate.  This is a case where it's not 
appropriate -- if something requires a parameter, it should be a method. 
  Otherwise you are hiding the parameter in another attribute, which 
will definitely lead to future confusion.
