Is there a straightforward way that I can pass a function to new
collection when I create my $map, so that the "error" would contain
the error string instead of the numeric code?
As it turns out, I needed the same kind of thing, so of course I added
that ability. With RowSets we have column expressions, you can do a
similar thing when setting up the map for addSelection(). Instead of
of giving a field pointer, just specify the text you want to execute,
which should evaluate to a value.
So in your example above, the map would become:
$map := new collection("id" ;
->[Mail_Queued_Messages]ID; \\
"status" ;
->[Mail_Queued_Messages]Message_Sent; \\
"error" ;
"getErrorMsg([Mail_Queued_Messages]Message_ErrorCode)"; \\
"queued_on" ;
->[Mail_Queued_Messages]Message_QueuedDTS; \\
"last_sent_on" ;
->[Mail_Queued_Messages]Message_LastSentDTS; \\
"subject" ;
->[Mail_Queued_Messages]Message_Subject )
If you need to execute an expression within 4D (because it uses
commands not supported by Active4D), prefix the expression with "!".
Awesome!
Do I understand correctly that I need to use RowSets for this to work? I
tried to change my simple example which uses a regular 4D selection and
Active4D is throwing an error about "expecting a pointer".
The Mail_ErrorText method is a 4D method. It calls a plugin method and
is accessed by 4D Client code too. So I need to call it like this?
"error" ;
"!Mail_ErrorText([Mail_Queued_Messages]Message_ErrorCode)"; \\
Thanks,
Brad
