Re: [flexcoders] Cairngorm commands - best practise

[hank williams]

Funny, I was just dealing with this same question. I did it at the command because it seemed to me that is where all the application logic should go and so any additional processing and data handling that must be done should be done in the command. But I wasnt 100% sure. That was my gut. I would be curious as well if anyone doing caringorm longer has any thoughts.

Hi there

 

Let's say I want to do a server
request. 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?

 

 

Cheers 

 

Robin
