BUT, one problem that comes not just with CakePHP but with several frameworks, is the usage of the Model. it’s not really a problem, but I think that is the way that people learned MVC with the framework, and the way that we see the Controller.

Frameworks, such as CakePHP, Rails and so on, impose that Model is database access (not really, but they come with this access).

Is that wrong? NOT really wrong…

As the fact that normally your application will need to save data into one database, or filesystem, etc… So provide one database access inside our model probably will help us.

What is the problem?

The problem comes when you see your model as JUST one database access layer, see the model as the thing that will store our data. So we start write the system logic inside the Controller, and this Controller starts to grow, because it already has several roles in our application, it handle the request, it handle the input, it call the model, it call the view… and it also get an additional role that is have the system logic. So our controller get FAT, hard to maintain, hard to change, hard to test, hard to change. It start to has the action methods, some other private/protected methods to implement logic, and it get ugly, strange, BIG.

What about our model?

The model keep thin, with no methods, no logic, just with the relationships of our database, with the validation… does it seems strange for you?

So what hell we are not using our model?

YES, we should use our model to make the logic of the system, is that the M of our application, is what Model must be, and is what the Model is expecting.

How we can start use our model as the logic part of our applications?

1. STOPING to see the Model as your database access;
2. Writing methods inside our models;
3. Creating models without usage of database;
4. Making the models talks each other;
5. Importing libraries, objects inside or model;
6. Creating one API inside or models, to make easy the calls for the controllers;
7. Make your controllers as  much thin as possible.

What will be your gains?

1. You will probably have more freedom to make your logic;
2. Your code will be more simple to maintain;
3. It’s simple to write test for Models;
4. You will have a better OO structure of your logic;
5. You will start think different about Behaviors, Components in CakePHP;
6. Your controller will be thin, and make just what he should do, nothing else;
7. You will stop rewrite code, the model can be called in any controller that you want;
8. With a good structure of logic, it will be so much easy to upgrade your code to new versions of  the framework, or why not, migrate to another framework, as the fact that your logic system will not depends more of the features that CakePHP has.

To summarize, CakePHP is great, it has great tools to make our development fast, but what we can not do is misunderstand the MVC, and starts to be addict with bad practices.  Frameworks like Zend make it more simple to understand, because it not provides directly in the model one database access, BUT anyway in CakePHP we can make the thing correct too, and get everything good of the framework.

So the idea behind the post is not forget the Controller, but pay much more attention in your Model.

I’m here to promote a new plugin to upload in CakePHP, the Attach plugin, that is based on MeioUpload, but it’s a bit different, he makes use of new Model API of CakePHP 2, where we have support to define own validations and use the Behavior as the method of validate, and also some new things.

A big difference is the use of Imagine Lib, to make the thumbnails, that gives a lot of features to manipulate images.

The plugin also implements polymorphic models, so we have one model/table that handles/store all the files, and your custom models have association with this Attachment model.

It’s really simple to use I hope you guys enjoy the plugin any improvement or feedback are welcome, and you are able to fork it.

Currently the plugin is in his first version, and improvements will be done in the API of the plugin also in the code.

Working with Documents from pimcore on Vimeo.

But your client also wanna administrate some PDF files, yep no problem for pimcore:

pimcore web2print from pimcore on Vimeo.

You have to create some dynamic contents, for example a news system, ok no problem for you Pimcore will provide for you a friendly interface where you haven’t to code to create one admin interface to create the news system for your client:

see more We need one good file administration, yep they know, and they have a good one:

In the end you ask but this works well, they answer this for you too with a showcase. I’m so impress with this CMS, it’s not normal i like something as much I liked this CMS, I’d like to congrats the team of pimcore, for this so great tool.

You can check some videos in their user at vimeo: http://vimeo.com/pimcore

Let’s go to the code:

So if you wanna retrieve a data from the last 30 days, or the last 15 days you can use the follow code:

1

SELECT * FROM posts WHERE date >= DATE_SUB(CURDATE(), INTERVAL 30 DAY) ORDER BY date DESC;

OR

1

SELECT * FROM posts WHERE date >= DATE_SUB(CURDATE(), INTERVAL 15 DAY) ORDER BY date DESC;

So there is a function DATE_SUB that makes the work for us, in resume DATE_SUB subtract a time value (interval) from a date, so we set the current date and subtract the interval that we want.

To use the code in the CakePHP it’s simple:

1

$this->Post->find('all', array('conditions' => array('Post.date >= DATE_SUB(CURDATE(), INTERVAL 15 DAY)')));

For others databases or also in the MySQL you can do the same with PHP code, so you just need subtract the time using PHP and pass it as a condition, for that we have the function strtotime.

1
2

$date = date('Y-m-d', strtotime("-30 day"));
$this->Post->find('all', array('conditions' => array('Post.date >=' => $date)));

Thinking about it I like the idea of crawlers that looking for specifics kind of subjects, and give for me all information that I want in just one place, and so there is one new website/crawler that I put it to public, is the Cake Cobaia, there will show informations of some sites that I guess are pertinent that talk about CakePHP, using social websites like informations about CakePHP in Twitter, also videos that talk about CakePHP and photos about CakePHP.

The aggregator show a limited number of information in the first page and it’s possible filter by types, Twitter, Web, Youtube, Flickr… I want in the future also create a filter by time etc…

I’m open for any suggestions about the project and I’d like receive some feedback, and I hope you enjoy it.
