La question revient souvent sur le forum ou sur IRC, alors voici un petit récapitulatif pour comprendre comment importer proprement un modèle au sein d’un contrôleur CakePHP lorsque l’on en a besoin. Le cas d’utilisation le plus typique est la mise en place d’un tableau de bord qui centralise des informations de divers Modèles de l’application.

I’m currently revamping the API of NoseRub to use CakePHP’s Router::parseExtensions() magic, i.e. if you append an extension like “.json” to the action you request, then CakePHP automagically sets the correct content type, and uses extension-specific layouts and views to render the result (e.g. if you request /example/action.json then the layout app/views/layouts/json/default.ctp and the view app/views/example/json/action.ctp are used by default).

That’s nice, however, in our case all JSON views are identical (the same applies for the XML views):

Eai galera!

Nos ultimos dias enfrentamos turbulências na realização da mudança do nosso servidor, cache do WP, e outras azias aleatórias .

O KISS ficou zuadão, mas agora (de acordo com o Bodão) está rodando normalmente:

Hj eu botei um sistema de cache de macho nele… agora eh cache de banco de dados, e nao cache de pagina completa… a separacao de contexto conteudo estatico e conteudo gerado por consultas eh bem mais interessante, gasta menos espaco em disco, menos processamento, e tudo acaba realmente ficando mais rapido…

Bom… sendo assim, gostariamos de deixar aqui nossas sinceras desculpas pelos transtornos =D

I have found some common code patterns/refactoring patterns while doing code reviewing in my current day job. And one of them involves switch blocks. After reading nate’s blog here about switch blocks, I thought to share something similar.<!--more-->

Following is an example code, where switch-case is used to configure some variables based on the value of $api_name.

I don’t like CAPTCHAs. I don’t know anyone who does. But most forms need some sort of protection against spam, especially where heavyweight spam detection services (e.g. Akismet) aren’t suitable. The downfalls of CAPTCHAs are many - hard to read, annoying, impossible for those with vision difficulties - and the benefits are slim. So, a few months ago I wrote a little function (and I do mean little - like 10 lines of code) to generate a random math question to ask the user in plain text instead of a CAPTCHA. The idea was that a bot wouldn’t be able to answer it, since it requires some human logic. And you know what? It worked - spam went way down on our websites.

if(isset($this->params['requested']))
	$this->Auth->allow($this->action);

I just spent about 3 hours pulling my hair trying to figure out why my CakePHP application was stuck in an infinite redirect loop when using the built-in Auth component. The above code snipped was the simple solution.

For the past month I have been talking about CakePHPs lack of a built in uploader component or mechanism, and how I wanted to build one. Well wouldn't it be great if I actually did build it? Oh wait, what is this? I did build one? Yes. Is it released? Yes. May I use it? Of course! The Uploader is primarily used as an all purpose file uploader and was built to not interact with a model/database. Here is a quick rundown of the plugin.

The plugin comes bundled with an uploader component and a validation behavior. The component is used to upload the files to a destination, resize or generate images, validate against mime types, log errors, scan for viruses and more. The behavior is used to add validation rules to a model to check against image uploads.

A big thank you to Mark Story and Matt Curry for beta testing and giving input and ideas.

What happens when you wait for half an hour to delete one row in your database? Investigation!

Have you experienced this for the APC install?
--------------------------
Sorry, I was not able to successfully run APXS. Possible reasons:

1. Perl is not installed;
2. Apache was not compiled with DSO support (--enable-module=so);
3. 'apxs' is not in your path. Try to use --with-apxs=/path/to/apxs
The output of /var/tmp/pear-build-cba/APC-3.0.19/y follows
/tmp/tmpwmgpL4/APC-3.0.19/configure: line 3232: /var/tmp/*****/APC-3.0.19/y: No such file or directory
configure: error: Aborting
ERROR: `/tmp/tmpwmgpL4/APC-3.0.19/configure --with-apxs=y' failed
--------------------------

The answer is:
"--with-apxs=y"
has to be
"--with-apxs=yes".

つまり、
-----------------
Use apxs to set compile flags (if using APC with Apache)? [yes] : y
-----------------
というのは間違いで、
-----------------
Use apxs to set compile flags (if using APC with Apache)? [yes] : yes

I’ve been using the the Meio Upload Behaviour for a while as its a very handy piece of code, but as is so often the case it doesn’t do quite what I need. In the past I’ve got round this by hacking together a kind of supporting framework in app_controller and scattered about in my models. But the other day I came across the newest version of the code by Juan Basso on Github and decided to dump my mess of spaghetti code and start from scratch.

Aims

The idea is that each model can have its own uploads with their own defaults, for example:

CakePHPでDebug Levelなどの設定を変更する際は、core.phpを修正するのが一般的です。インストール直後にSecurity.saltを変更するのはお馴染みですね。

そんなcore.phpですが、実はこの設定はbootstrap.phpに記述してもokです。例えば以下のようにDebug Levelをbootstrap.phpに記述するとDEBUG=0として動作します。

[app/config/bootstrap.php]

なぜFに舞い戻ったか。

答え：iモードブラウザ2.0で、タブ機能が全機種に搭載されたから。

まあこれだけです。逆にいうと、Nに移ったのはタブブラウザのためのみでした。F905iはかなり気に入った部類の端末でしたが、iモードブラウザ2.0登場以前でiモードブラウザでタブ機能を備えていたのは僕の知る限りNのみでした。どうしてもiモードでタブブラウザを使いたかったし使ってみたかったので思い切って機種変更したのでした。4～5万くらいかかったかな。

ちなみにN-02Aで他にも良かったのは、当時Nのみがサポートしていたiモードでのタブブラウジングに加えて、最薄級の端末でありながらGPSを搭載していたこと。最新F-08Aよりも薄くて軽い端末ながら、GPSの搭載はなかなかのものと思われます。（N-02Aは防水ではありませんが）

N-02Aのタブブラウザはよくできていて、ソフトキー一発でリンクを別タブで開くことができます。タブ切り替えもソフトキーで一発です。
