Hi
I'm trying to build an installation procedure for my site based on
cakephp; thus I have an updates table where information concerning
version updates are stored. However, I need to bootstrap this procedure
so the first thing the installation script does is to check whether the
database exists and the updates table exists (and is not empty): in such
case it's a brand new installation. So I put some of this logic in the
UpdatesController but I have the problem that the model Update cannot
find the table.
Now, what I did, is to create an InstallsController with $uses=null so
that I can perform these bootstrap checks from there. This should be
fine, shouldn't it?
thanks

Yes like Nabil said, most models should be related to a table. If you
are trying to figure out if a table exists, then you shouldn't have a
model.
Can you explain your situation a bit more?

Controllers expect to have a model which in turn expects to have a table
in the DB by default. If you have a controller that doesn't use a model
set $uses to 'null' or an empty array... if you have a model that
doesn't have a datasource then look at $useTable and $schema variables
inhttp://api.cakephp.org/class/model

The problem I have with my solution, but I guess it's the same of the
one of the link, is that if I use it inside a controller, I get an error
before even reaching that code, due to a missing table... is there a way
to avoid this?
Of course I need this check for an installation page, which I'm
developing using a controller...
thanks in advance

You can try this, then see if your table exists within the array.

Hi
is this a correct way of checking whether a table exists?
function check_table_exists($table) {
$dbo = $this->getDataSource();
$result = $dbo->_execute('DESCRIBE '.$table);
return !empty($result);
}
thanks in advance
