What I mean is.
I hate hard coding. Its been a while since I have done web programming.
And one think I always disliked has been hardcoding relationships (URLs)
between forms.
I have not finished implementing this yet, but I believe it will work
effectivly.
I like a much more dynamic and database driven approach with to goals in
mind:
1.Give our users a easy way of customizing the system.
2.Have the ability of supplying multiple views to the system
(User/Admin/Customer/Consultant, etc...)
In a database you must have users related to a view/profile.
You have a base set of forms in the system. Users an "Overide" this base
form by providing their own version.
So for instance you have the base form:
"user_view" mapped to base_user_view.jsp
And a users customized from:
"user_view_custom" mapped to user_view_custom.jsp
Each form in the system will as we all know now map to "AppController". The
AppController in my scenerio will execute an Jpythoin script action.
The action (related to the callee form) will return the next view to goto.
The AppController then must decode what is the proper version to show of the
logical view based on the "logical" form name and the User's profile/view of
the system.
The are two elements of control that the AppController implements(at least
I can think of):
1.What is the next destination (View) of the Action . (example: Error or
View)
2.What is ther version of the view (User/Admin/etc...)
The other way to code this is putting the control logic in the
View(JSP).
if (user.type == USER.Admin)
Show this element
Else if (user.type == USER.User)
Show some other element
Does this help?
