Hello together!
I'm currently playing around with fcl-web a bit.
As I'd like to utilize inversion of control (e.g. passing things like
database connections through the constructor [as one possible
implementation of this pattern]) for my modules I'd like to ask
whether it would be an idea
whooohoo - expensive terminology detected !!
"Inversion of Control" :-)
Sorry, but I don't get what you want to tell with that statement... :(
(maybe my brain is all smashed today after I've read the documentation
of a Delphi ORM ^^)
for a feature request (maybe even with patch) to add an
"OnCreateModule" event to TWebHandler which is called inside
TWebHandler.HandleRequest before the module is created using CreateNew
or Create?
Well, it can only be after create. You need the instance first, and it
is constructed with Create(New).
That's the point: add an event which creates the module with custom
parameters (because the module then can use a custom constructor). But
see below.
If you need to do something before that, there already is the
OnGetModule handler.
But OnGetModule only returns the class, not an instance...
But yes, a centralized initialization handler for webmodules is OK.
Something like 'OnInitModule' or so ?
That's also an idea. At least then the creation of the module is kept
inside TWebHandler (to use another expression: "open for extension, but
closed for modification" ;) )
Regards,
Sven
