Re: datasource and count()
2010/1/27 John Andersen j.andersen...@gmail.com:
Ok, I would like to understand what is your issue here, because I do
not see a calculate method in the DataSource class! Do you mean the
DboSource?
John
I tried to make a $this-Image-find('count'); on the model with my
datasource, and it gives error:
Fatal error: Call to undefined method FilewidSource::calculate() in
/home/fain182/workspace/cake/libs/model/model.php on line 2042
if you read the source of _findCount() you see that use calculate..
http://api.cakephp.org/view_source/model/#line-2040
maybe with a behaviour i could change this..
but it's a little dirty make a datasource that depends on behavior..

Re: datasource and count()
Ok, then it is not in the your DataSource class there is a need for
the calculate method, but in your generic filesystem class, to which
the DataSource refers to (through configuration).
As I understand, CakePHP use a DataSource to provide an implementation
independent interface to the DboSource (plus subclasses)
implementation dependent interface.
Thus your FilewidSource class (the implementation dependent interface)
should provide the calculate method.
Am I correct in my understanding of your issue?
Enjoy ;)

How do you search for your files that fulfill your criteria?
If you are using a pattern, like *.txt, then you could just use the
function glob(*.txt) to return the filenames and dirnames that
comply with the pattern. The result is an array, which you can
count :)
no, i need something more complex, and i want do it in the more cake-ish way
possible..
I have a model Image that use my datasource, and everything works, but if i
want to know the number of row that will return a find i must have code
like:
count( $this-Image-find('all', array('conditions'=...)) );
but it's a little bit dirty..
and i wanted to have something like:
$this-Image-find('count', array('conditions'=...))
but i didn't found documentation on how to implement something like this,
and reading the code, seems that find('count',...) is possible only for sql
based datasource..
There is no need to worry about the reference to COUNT in MySql, that
is only if you are using a database.
no, i want COUNT in a datasource that is not SQL..

Re: datasource and count()
no one ever tried to write a datasource with count included and not
for an SQL database?
2010/1/21 fain182 fain...@gmail.com:
Hello,
I wrote a little datasource that i need to browse the filesystem..
find('all'), find('first') works without any problem, but I tried to
use find('count') and I discovered that I need to implement
calculate() on my datasource..
but calculate documentation says that Returns an SQL calculation,
i.e. COUNT() or MAX() !?
find(count) can be used only by SQL based datasource??
or I am missing something?
thank you
PS: it would be cool add some information about this in the cookbook too..
