[flexcoders] Cairngorm commands - best practise

[Bjorn Schultheiss]

hmm, sorry.   I thought you wanted to check userID in the command.onResult()   It would have to be in the command. The result handlers are frequently used to update the model, therefore it should be no issue to reference the model in the execute method.   Good question   Regards,   Bjorn Schultheiss Senior Flash Developer QDC Technologies   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of hank williams Sent: Wednesday, 11 October 2006 12:36 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Cairngorm commands - best practise Hmm... I'm not sure, but I dont think you understood the question. Your answer, as far as I can tell, does not seem responsive. But I'm not sure that I could repeat it and make it any clearer than robin's initial question. Perhaps you could re-read it.

I want to search my database for a particular keyword and return a record set. The user would type in the keyword in a text area and I would then create a SearchDatabaseEvent which then would trigger a SearchDatabaseEventCommand and so on … However I also want to send the userID when I do my server request. Should the SearchDatabaseCommand get the userID from the model or from the SearchDatabaseEvent (so I would have two properties in my event "keywords" and "userId")? The SearchDatabaseCommand obviously knows about the model because it has to populate the model with the result record set. So I could just get the user ID from the model when the "execute method" is triggered. This approach seems a bit wired though because it seems that couples my command to strongly to the model. On the other hand it seems strange to query the model from my view to populate the SearchDatabaseEvent with userId property as well. Any thoughts?
