Re: Finding related articles
I completely agree, both with the point about it being difficult to use Cake for advanced applications (or just non-standard CRUD sites) without prior knowledge of SQL, and about not picking up bad habits by developing within an MVC framework from the get-go. Personally, I'm not as familiar with SQL as I'd like to be either (don't know how to use triggers, stored procedures, build indexes, create constraints, etc.), even though I've been developing with it for over 7 years, as I've never taken a formal course on database design/development/administration. But I have the dev.mysql.com (as well as php.net, jquery.com, Cake API/Cookbook, MDC, etc.) search tool install with search keywords configured so that I can just type "mysql distinct" into the Firefox address bar, and it will search the online MySQL documentation for the DISTINCT keyword--it doesn't work quite as well as php.net's search function, which will automatically take you to the page for that function/class/topic, but it still saves me a lot of time since I'm looking up stuff in the MySQL manual all day long. MySQL's online documentation can be quite dense at times, as it also assumes that you have formal training in SQL and relational databases, but the user comments are pretty helpful and often includes example code. But the best way to learn (aside from taking an academic course) is just to practice writing lots of MySQL queries using the command- line client or write practice PHP+MySQL apps using manual queries instead of Cake's model functions. You should do this at least until you're proficient enough in SQL that you can write your Cake application without the use of Cake's database abstraction (e.g. know how to use SELECT, INSERT, UPDATE, DELETE, as well as basic uses of joins and even subqueries). Once you've done that, then you can let Cake handle most of the menial queries and use GUI clients to administer your database.

Re: Finding related articles
It is going to be a little more difficult for you coming to this without any prior knowledge of databases. However, I wish I had worked within the constraints of this framework (OOP/MVC Design Pattern) before I had the chance to teach myself a lot of bad habits so you have that going for you. Whilst book.cakephp.org does mention the use of DISTINCT and GROUP etc. it is likely to cover them as if you already know what they do. It may be worthwhile reading through some MySQL tutorials (I assume you're using MySQL) just to get your head around the possibilities open to you. I have never read through a tutorial from start to finish but a quick Google found this one which seems to cover most of the functions: http://www.tizag.com/mysqlTutorial/ someone else may be able to recommend a better one though.

Re: Finding related articles
Look in the CakePHP book at: http://book.cakephp.org/view/1017/Retrieving-Your-Data and browse through each section, so that you can find the examples for DISTINCT, grouping, OR, etc. Complex find at: http://book.cakephp.org/view/1017/Retrieving-Your-Data#Complex-Find-Conditions-1030 as well as grouping described in: http://book.cakephp.org/view/1017/Retrieving-Your-Data#find-1018 Enjoy, John On May 11, 6:59 am, jthommo wrote: > Thanks Paul, > > I'll give it a go. > > You're right - the teknoid.wordpress.com site has a good bunch of > HABTM stuff on it, in > particular:http://teknoid.wordpress.com/2008/08/06/habtm-and-join-trickery-with-... > > I think what I'm really missing is more detail on the various > parameters you can stick into find().

Re: Finding related articles
Thanks Paul,
I'll give it a go.
You're right - the teknoid.wordpress.com site has a good bunch of
HABTM stuff on it, in particular:
http://teknoid.wordpress.com/2008/08/06/habtm-and-join-trickery-with-cakephp/
I think what I'm really missing is more detail on the various
parameters you can stick into find(). In your example, you've used
DISTINCT and OR and in the linked-to article they use 'group'. Where
are these coming from? Am I missing this as I'm new to SQL in general?
The book isn't exactly detailed in this area...
Thanks a lot,
Jeremy

Re: Finding related articles

HABTM stuff on it, in particular:
http://teknoid.wordpress.com/2008/08/06/habtm-and-join-trickery-with-cakephp/
I think what I'm really missing is more detail on the various

DISTINCT and OR and in the linked-to article they use 'group'. Where
are these coming from? Am I missing this as I'm new to SQL in general?

Re: Finding related articles
Firstly, welcome to the community and to the joys of CakePHP
Secondly, HABTM is where a lot of people tend to start tripping over
themselves as it's really a convenience method to join 3 tables
together with minimal coding and doesn't always have the flexibility
of what should ideally be a
ModelA hasMany JoinModel
ModelB hasMany JoinModel
JoinModel belongsTo ModelA
JoinModel belongsTo ModelB
The book touches on finding recipes by tag very lightly on page:
http://book.cakephp.org/view/83/hasAndBelongsToMany-HABTM
However to really get my head around HABTM I spent some time reading
Teknoids articles on the subject
http://teknoid.wordpress.com/?s=habtm
He also created a Habtamable behaviour which I am yet to try using
myself:
http://teknoid.wordpress.com/2009/09/26/habtamable-behavior/
The book example gives you a couple of examples of how to fetch data
relating to a certain tag and Teknoid expands on those.
I think from what you are saying and looking at the book's example you
should be able to get close to what you want by using
$this->Article->Tag->find('all', array('conditions'=>array(
'OR'=>array(
'Tag.name'=>'Tag1',
'Tag.name'=>'Tag2',
'Tag.name'=>'Tag3'
)
)));
Grouping your conditions in an OR array will fetch any article that
matches any of the tags rather than all of them, but then you will
have to tackle the problem that this will not fetch UNIQUE articles.
You will have to experiment with something along the lines of
$this->Article->Tag->find('all', array(
'fields'=>array('DISTINCT Article.id', 'Article.title',
'Article.???')
'conditions'=>array(
'OR'=>array(
'Tag.name'=>'Tag1',
'Tag.name'=>'Tag2',
'Tag.name'=>'Tag3'
))
));
Hope this helps,
Paul
