Trouble retrieving data laravel4(oneToMany) - php

Question

Okay so I just started learning Laravel and its fantastic. I just got stuck trying to retrive all the post from a user. Here is my code
models/User.php
public function posts()
{
$this->hasMany('Post');
}
models/Post.php
public function user()
{
$this->belongsTo('User');
}
controller/UserController.php
public function getUserProfile($username)
{
$user = User::where('username', '=', $username)->first();
$this->layout->content = View::make('user.index', array('user'=>$user));
}
views/user/index.blade.php
<div class="show-post">
<ul>
<li>{{ $user->posts }}</lo>
</ul>
</div>
I also tried:
#foreach($user->posts as $post)
<li>{{$post->post}}</li>
#endforeach
So im having trouble displaying the post for each specific user. Thank you.

So with the help of #WereWolf- The Alpha I was able to solve it and make my code better, If you notice I forgot to return my relationship functions. example:
Notice I hadn't returned it before
models/Post.php
public function users()
{
return $this->belongsTo('users');
}
But also the way I was querying my database was inefficient so Alpha showed me Eager Loading
http://laravel.com/docs/eloquent#eager-loading
example of controller
public function getUserProfile($username)
{
$user = User::with('posts')->where('username', '=', $username)->first();
$this->layout->content = View::make('user.index', array('user'=>$user));
}
and finally the view:
div class="show-post">
#foreach($user->posts as $post)
{{ $post->post }}
#endforeach
</div>

Actually $user->posts returns a collection of Post model so when you try this
{{ $user->posts }}
Laravel tries to echo that collection object which is not possible. You may try foreach loop instead:
#foreach($user->posts as $post)
{{ $post->somepropertyname }}
#endforeach
It's also possible to do something like this:
// Get first post->somepropertyname
{{ $user->posts->first()->somepropertyname }}
// Get last post->somepropertyname
{{ $user->posts->last()->somepropertyname }}
// Get first post->somepropertyname (same as first)
{{ $user->posts->get(0)->somepropertyname }}
// Get second post->somepropertyname from collection
{{ $user->posts->get(1)->somepropertyname }}
// Get the post->somepropertyname by id (post id) 2
{{ $user->posts->find(2)->somepropertyname }}
Also you may use eager loading like this (better):
$user = User::with('posts')->where('username', '=', $username)->first();

Update: Also use return in model methods, like:
public function posts()
{
return $this->hasMany('Post');
}
