Laravel 4 系列入门教程（一）【最适合中国人的Laravel教程】
基于最新 Laravel 5.2 的 2016 版教程已经发布到 Github：https://github.com/johnlui/Learn-Laravel-5/issues/4
十分建议学习 5.2，4.2 早已不再维护。
向 Laravel 4 – simple website with backend tutorial – Part 1 致敬，本教程部分内容翻译自此文章。
每一个教程完成，我将会git commit一次。
示例代码见 https://github.com/johnlui/Learn-Laravel-4
大家在任何地方卡住，最快捷的解决方式就是去看我的示例代码。

0. 默认条件
本文默认你已经有配置完善的PHP+MySQL运行环境，懂得PHP网站运行的基础知识。跟随本教程走完一遍，你将会得到一个基础的包含登录的简单blog系统，并将学会如何使用一些强大的Laravel插件和composer包（Laravel插件也是composer包）。
软件版本：PHP 5.4+，MySQL 5.1+
本文不推荐完全不懂PHP与MVC编程的人学习。本文不是 “一步一步跟我做” 教程。本文需要你付出一定的心智去解决一些或大或小的隐藏任务，以达到真正理解 Laravel 运行逻辑的目的。
1. 安装
许多人被拦在了学习Laravel的第一步，安装。并不是因为安装教程有多复杂，而是因为【众所周知的原因】。在此我推荐一个composer全量中国镜像：http://pkg.phpcomposer.com/。推荐以 “修改 composer 的配置文件” 方式配置。
镜像配置完成后，切换到你想要放置该网站的目录下，运行命令：
composer create-project laravel/laravel learnlaravel 4.2.11
为了大家学习的方便，请暂时使用 4.2.11 版本进行入门。春节假期我会抽时间写一下 Laravel 5 的入门教程。4.2.11 的 Github 下载地址为：https://github.com/laravel/laravel/archive/v4.2.11.zip
然后，稍等片刻，当前目录下就会出现一个叫 learnlaravel 的文件夹，这时候如果你通过浏览器访问 learnlaravel/public/ 目录，基本都会显示 Error in exception handler. ，这是因为 learnlaravel/app/storage 目录没有 777 权限，设置好权限即可看见页面如下图：
恭喜你~Laravel安装成功！
不想配置镜像的同学，可以使用 Laravel 界非常著名的超超搞得安装神器：https://github.com/overtrue/latest-laravel
2. 必要插件安装及配置
我们使用著名的Sentry插件来构建登录等权限验证系统。
打开 ./composer.json ，变更为：
"require": {
"laravel/framework": "4.2.*",
"cartalyst/sentry": "2.1.4"
},然后，在项目根目录下运行命令
composer update
然后稍等一会儿，它会提示 cartalyst/sentry 2.1.4安装完成。
同理，我们将安装一个开发用的非常强大的插件，way/generators，这是它在composer库中的名字。在 composer.json中增加：
"require-dev": {
"way/generators": "~2.0"
},和“require”同级，放在下面，不是里面哦~。
运行 composer update，之后在 ./app/config/app.php 中 恰当的位置 增加配置：
'Way\Generators\GeneratorsServiceProvider'
安装完成过，在命令行中运行 php artisan，就可以看到这个插件带来的许多新的功能。
有人会问，为什么用了国内镜像还是如此之慢？其实composer在update的时候最慢的地方并不是下载，而是下载之前的依赖关系解析，由于Laravel依赖的composer包非常之多，PHP脚本的执行速度又比较慢，所以每次update等个两三分钟很正常，习惯就好。
3. 数据库建立及迁移
数据库配置文件位于 ./app/config/database.php，我们需要把“connections”中的“mysql”项改成我们需要的配置。下面是我的配置：
'mysql' => array( 'driver' => 'mysql', 'host' => 'localhost', 'database' => 'laravel', 'username' => 'root', 'password' => 'password', 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => 'l4_', ),
prefix为表前缀，这个Laravel会帮我们自动维护，大胆写上不用担心。
这时候你需要去数据库建立此数据库，然后在命令行中输入：
php artisan migrate --package=cartalyst/sentry
执行完成后，你的数据库里就有了5张表，这是sentry自己建立的。sentry在Laravel4下的配置详情见 https://cartalyst.com/manual/sentry#laravel-4，我大致说一下：
在 ./app/config/app.php 中 相应的位置 分别增加以下两行：
'Cartalyst\Sentry\SentryServiceProvider',
'Sentry' => 'Cartalyst\Sentry\Facades\Laravel\Sentry',
权限系统的数据库配置到此为止。
我们的简单blog系统将会有两种元素，Article和Page，下面我们将创建articles和pages数据表，命令行运行：
php artisan migrate:make create_articles_table --create=articles php artisan migrate:make create_pages_table --create=pages
这时候，去到 ./app/database/migrations，将会看到多出了两个文件，这就是数据库迁移文件，过一会我们将操作artisan将这两个文件描述的两张表变成数据库中真实的两张表，放心，一切都是自动的。
下面，在***_create_articles_table.php中修改：
Schema::create('articles', function(Blueprint $table)
{
$table->increments('id');
$table->string('title');
$table->string('slug')->nullable();
$table->text('body')->nullable();
$table->string('image')->nullable();
$table->integer('user_id');
$table->timestamps();
});
在***_create_pages_table.php中修改：
Schema::create('pages', function(Blueprint $table)
{
$table->increments('id');
$table->string('title');
$table->string('slug')->nullable();
$table->text('body')->nullable();
$table->integer('user_id');
$table->timestamps();
});
下面，就是见证奇迹的时刻，在命令行中运行：
php artisan migrate
这时候数据库中的articles表和pages表就建立完成了。
4. 模型 Models
接下来我们将接触Laravel最为强大的部分，Eloquent ORM，真正提高生产力的地方，借用库克的话说一句，鹅妹子英！
我们在命令行运行下列语句以创建两个model：
php artisan generate:model article php artisan generate:model page
这时候，在 app/models/ 下就出现了两个文件 Article.php 和 Page.php，这是两个 Model 类，他们都继承了Laravel提供的核心类 \Eloquent。这里需要强调一下，用命令行的方式创建文件，和自己手动创建文件没有任何区别，你也可以尝试自己创建这两个 Model 类哦。
Model 即为 MVC 中的 M，翻译为 模型，负责跟数据库交互。在 Eloquent 中，数据库中每一张表对应着一个 Model 类。
如果你从其他框架转过来，可能对这里一笔带过的 Model 部分很不适应，没办法，是因为 Eloquent 实在太强大了啦，真的没什么好做的，继承一下 Eloquent 类就能实现很多很多功能了。详见 Eloquent 系列教程：深入理解 Laravel Eloquent（一）——基本概念及用法
5. 数据库填充
分别运行下列命令：
php artisan generate:seed page php artisan generate:seed article
这时，在 ./app/database/seeds/ 下就出现了两个新的文件，这就是我们的数据库填充文件。Laravel提供自动数据库填充，十分方便。
generator默认使用Faker\Factory作为随机数据生成器，所以我们需要安装这个composer包，地址是 https://packagist.org/packages/fzaninotto/faker ，跟generator一起安装在 require-dev 中即可。具体安装请自行完成，可以参考Sentry和Generator，这是第一次练习。
接下来，分别更改这两个文件：
Article::create([ 'title' => $faker->sentence($nbWords = 6), 'slug' => 'first-post', 'body' => $faker->paragraph($nbSentences = 5), 'user_id' => 1, ]);
Page::create([ 'title' => $faker->sentence($nbWords = 6), 'slug' => 'first-page', 'body' => $faker->paragraph($nbSentences = 5), 'user_id' => 1, ]);
然后，我们需要在 DatabaseSeeder.php 中增加两行，让Laravel在seed的时候会带上我们新增的这两个seed文件。
$this->call('ArticleTableSeeder');
$this->call('PageTableSeeder');下面就要真正的把数据填充进数据库了：
php artisan db:seed
操作完成以后去数据库看看，数据已经填充进去了，article和page各10行。

看完第一章，非常有用。谢谢老师。
只是文中下面这段代码，是不是粘贴重复了，和数据表结构对应不上啊。
Article::create([
'title' => $faker->sentence($nbWords = 6),
'slug' => 'first-post',
'body' => $faker->paragraph($nbSentences = 5),
'user_id' => 1,
]);
Page::create([
'title' => $faker->sentence($nbWords = 6),
'slug' => 'first-page',
'body' => $faker->paragraph($nbSentences = 5),
'user_id' => 1,
]);

这个Faker\Factory或者fzaninotto/faker怎么安装？这个问题搞了我一个星期了，很急，很重要，我们就要用laravel做项目的
我是在github下载了 faker 的安装包解压到 vendor 目录下，然后又在 app\config\app.php 文件的 'providers' 数组中添加了 'Fzaninotto\Faker\FakerServiceProvider'。就是不行，一直报错“ymfony \ Component \ Debug \ Exception \ FatalErrorException (E_UNKNOWN)
Class 'Fzaninotto\Faker\FakerServiceProvider' not found ” ；求详细安装教程！

成功! 见到了楼主所说的丑页面。谢谢楼主！
总结一下，从安装到现在，遇到了几处难点：
1,安装第一步，“切换到你想要放置该网站的目录下”
一开始不知道网站根目录指的是哪里，还以为是public目录，百度上问也没人回答，google外国网站，才得知是app的父目录，这个难点差点把我挡在laravel门外。如果教程中写明网站的目录就是app的父目录就好了。
2,"require": {
"laravel/framework": "4.2.*",
"cartalyst/sentry": "2.1.4"
},
4.2.*原封不动就这样写。不要写成4.2.11之类的。
3,composer.json就在learnlaravel根目录下。我一开始用的是/learnlaravel/vendor/laravel/framework/src/Illuminate/Support/composer.json,导致安装Sentry等插件失败。
4,View [admin._partials.assets] not found.
不知道admin._partials.assets放在哪个目录下，看评论才知是在\app\views\admin\_partials目录下添加assets.blade.php这个文件，刷新后提示找不到admin._partials.navigation，如法炮制一下就好了。

其实使用了Sentry的话 查询关联的时候是不是不能关联到其他的表呢？
如这样的关联关系User->Information，是一对一的关系。user的model与information的model都有hasOne()。可是当我使用$user->information->description时会报这样的错Trying to get property of non-object。而使用Eloquent的话，$information = User::find($id)->information;是没问题的。我这样的推断是对吗？

数据库表只能是复数吗。。。
我自己创建的problem表，在seed填充时，它非得去找problems这张表。。。
有没有方法设置不自动寻找表名的复数形式。。

最后原因是：我在app.app加了Faker\Factory这样一个命名空间

@JohnLui：你好，晚上才有时间弄，我把原来的工程删了，从头开始做，在安装sentry和generrator的时候提示：could not scan for classes inside app/commands which does not appear to be a file nor a folder。
我没管，然后删掉了local文件夹并在app.php中providers添加了'Way\Generators\GeneratorsServiceProvider'，执行php artisan还是错误，删掉就好用。composer.json里的sentry版本都是从教程中复制过来的（composer.json是建工程之前我自己建的，貌似没问题吧）
有点小伤感

对了，由于 Laravel 的 you have arrived 页面的 css 会加载 google font ，造成每次打开都要等上至少一分钟。
解决方法是，先下载Lato字体，然后找到 learnlaravel\app\views 目录下的 hello.php 文件修改：
- /*@import url(//fonts.googleapis.com/css?family=Lato:700);*/
+ /* latin-ext */
@font-face {
font-family: 'Lato';
font-style: normal;
font-weight: 700;
src: local('Lato Bold'), local('Lato-Bold'), url(http://fonts.gstatic.com/s/lato/v11/ObQr5XYcoH0WBoUxiaYK3_Y6323mHUZFJMgTvxaG2iE.woff2) format('woff2');
unicode-range: U+0100-024F, U+1E00-1EFF, U+20A0-20AB, U+20AD-20CF, U+2C60-2C7F, U+A720-A7FF;
}
/* latin */

}
或者修改成其他字体。

@JohnLui：./app/config/app.php 中增加配置
鬼知道这个增加配置是怎么增加的啊？
你这是入门+教程，这样写算是入门+教程？
要不是去看https://github.com/JeffreyWay/Laravel-4-Generators 的安装步骤写清楚了"add a new item to the providers array."，真的新手入门冲着这个适合中国人的标题来看，能明白这一步的配置往哪增加？
还说向http://www.codeforest.net/laravel4-simple-website-with-backend-1 致敬，看看人家怎么写的：EDIT: Some people complained there’s not enough info on installing Sentry, so basicaly you need to add the service provider and the alias to your app/config/app.php file:
如果你的标题不是 入门+教程+最适合中国人，我不会说什么。

@ilvsx："入门教程" 并不是 “一步一步跟我做”，我在教程的某些地方刻意留下一些大大小小的任务，就是要让学习的人自己去尝试着解决问题，在解决问题的过程中感受 Laravel 做事的逻辑。很多人确实会卡在这一步，评论里面已经有几个人的反馈了。其实我想写清楚也很容易，大不了贴个我在 Github 上相应文件的链接，但是我不想这样干，想让大家在卡住之后自己仔细看下这个文件中的代码，或者想到去看我的代码，学习自己解决问题的能力。要不我的教程是没有价值的，一步一步跟我做完之后还是不会自己往下做，遇到问题了也不会自己解决。还是要感谢你的回复，也会给后来者以帮助。

php artisan generate:model article
php artisan generate:model page

php artisan generate:seed article
运行错误，显示：
[InvalidArgumentException]
There are no commands defined in the "generate" namespace.
已经在composer.json中配置，如下
"require-dev": {
"way/generators": "~2.0",
"fzaninotto/faker": "1.5.*@dev"
},
没有在app.php中写配置，不知道要不要，新手不是很懂。

最后一步 php artisan db:seed 的时候出错。
[PDOException]
SQLSTATE[HY000]: General error: 1364 Field 'image' doesn't have a default v
alue
原因分析是：
在***_create_articles_table.php中修改：
Schema::create('articles', function(Blueprint $table)
{
$table->increments('id');
$table->string('title');
$table->string('slug')->nullable();
$table->text('body')->nullable();
$table->string('image')->nullable();
$table->integer('user_id');
$table->timestamps();
});
中 $table->string('image')->nullable(); 设置成了必填项导致。
解决方案我认为有两种：
1： $table->string('image')->nullable(); 修改成——> $table->string('image');
2：数据数组中列添加相应值
Article::create([
'title' => $faker->sentence($nbWords = 6),
'slug' => 'first-post',
'body' => $faker->paragraph($nbSentences = 5),
'image' =>'xxxxxxxxxxxxxxxxxxxxxxxx',
'user_id' => 1,
]);

Faker\Factory的安装，配置文件貌似不是在require-dev里，而是require里，官方说明里有，不知道应该是到底选哪个，好像如果是dev的必须也要对应dev版，如果是fzaninotto选择1.4.0，还是放在require里。

@Julian：require-dev 和软件版本没有任何关系，你理解有误。
require-dev 是 Composer 的配置项，意思是开发用插件，线上部署的时候不用。默认的 composer update 是包含 dev 的，所以其实现阶段象征意义大于现实意义。Laravel可能会在部署的时候根据环境变量选择自动加载包，以达到减小命名空间树的目的（猜测）。

請問兩個文件的位置
*********************************
接下来，分别更改这两个文件：
Article::create([
'title' => $faker->sentence($nbWords = 6),
'slug' => 'first-post',
'body' => $faker->paragraph($nbSentences = 5),
'user_id' => 1,
]);
Page::create([
'title' => $faker->sentence($nbWords = 6),
'slug' => 'first-page',
'body' => $faker->paragraph($nbSentences = 5),
'user_id' => 1,
]);

@newbie2005：看上文：
这时，在 ./app/database/seeds/ 下就出现了两个新的文件，这就是我们的数据库填充文件。Laravel提供自动数据库填充，十分方便。

这两句有错误，不应该是migrate:make，而是make:migrate
