Re: Changing datasources to support web services.
Because I like to answer my own questions, I found the solution to
this.
Here's how you set up the map for your new service:
name your file 'app/models/datasources/type_source.php' (e.g.,
'web_services_source.php')
your class name will be the StudlyCaps version of that (e.g.,
'WebServicesSource'), defined in the above file.
Set up a map for that datasource to a name in database.php's
DATABASE_CONFIG class:
var $whatever = array('datasource' = 'type'); (e.g.: var
$web_services = array('datasource' = 'web_services'))
The datasource value is the name of your datasource file w/o the
'_source.php' at the end. The name of the variable ($web_services),
can be whatever you want.
In your model, tell it to use your new data source. I did this in the
constructor with:
$this-setDataSource('whatever');
Where 'whatever' is the name of your variable in the DATABASE_CONFIG
class.
I'm probably doing that last part wrong, but it seems to work for me.

Re: Changing datasources to support web services.
instead of doing:
$this-setDataSource('whatever');
you can do that:
class MyModel extends AppModel {
$useDbConfig = 'whatever';
//...
}

Changing datasources to support web services.
I've seen this question asked in this group a few times, but I
couldn't really parse out an answer, so I'm asking again.
From what I've read of the source code, it /appears/ as though you
can set the datasource for a model to, for instance, use a web
service.
It appears as though it's not much harder than overriding create/read/
update/delete in a subclass of DataSource. However, I can't seem to
get the data source in use at all. I suspect this has to do with which
files get loaded when (h00ray for file-based source code!).
I'm also not quite sure where to put the code for this. I've shoved
it in app/vendors now, but that doesn't seem quite right, since it
ain't third party, but a first-party generic library.
So, I have this data source defined in 'app/vendors/
web_services_data_source.php', and I have a model which require()s it
(again, not very pretty, and I'd like to not have to do that in every
model), and that's fine, but when I try to load the page I get:
[SNIP]
Fatal error: ConnectionManager::getDataSource - Non-existent data
source WebServicesDataSource in /home/bjc/src/cake_test/htdocs/cake/
libs/model/connection_manager.php on line 110
[SNIP]
And I can't figure out why. By this point, my model has been loaded
and the data source module has been loaded by require() (I know,
because if I change the arg to require, it barfs without displaying
the message above). So why can't ConnectionManager find it?
I specify $this-setDataSource('WebServicesDataSource') in the
constructor of the model I'm using. I've also tried
'web_services_data_source', but it has the same error.
Can anyone give me any pointers?

Re: Changing datasources to support web services.
you would put a class that extends DataSource in /app/models/ datasources then create a connection in database.php that can be used. you could use the xml class to get the web service. here is a datasource I started on for imap. never completed beyond making the initial connection, but it provides a good skeleton for your own datasource. http://bin.cakephp.org/view/1531034840 I know someone was working on an xml datasource. He was in the IRC channel a little while ago, but I have not heard from him in a little while. hope this helps. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Cake PHP group.
