How can I make a row of relations in laravel? - php

Question

I am struggling with this for a while now, but I can't figure it out how it works.
In laravel I have a few models with relationships. I wan't to have al the accounts based on the logged in user and the passed parameter for the workspace.
This is how the models looks like: (I only coppied the methods to keep it short)
The user Model:
class User extends Eloquent implements UserInterface, RemindableInterface {
public function workspaces()
{
return $this->hasMany('Workspace', 'user_id');
}
public function account()
{
return $this->hasManyThrough('account', 'Workspace', 'id', 'workspace_id');
}
}
The workspace model:
class Workspace extends Eloquent implements UserInterface, RemindableInterface {
public function account()
{
return $this->hasMany('account', 'workspace_id', 'id');
}
public function user()
{
return $this->belongsTo('User', 'user_id', 'id');
}
}
The account model
class account extends Eloquent implements UserInterface, RemindableInterface {
public function account_url()
{
return $this->hasOne('acountUrl', 'id', 'account_url_id');
}
public function workspace()
{
return $this->belongsTo('Workspace', 'workspace_id', 'id');
}
}
The account_url model
class account_url extends \Eloquent implements UserInterface, RemindableInterface {
public function account()
{
return $this->belongsToMany('account', 'id', 'account_url_id');
}
}
So I want from the logged-in user with a specific workspace all the account with the account_urls
something like this: user->workspace->account->account_url
I tried the following things but it don't work:
$account_urls = user::find( Auth::user()->id)->first()->workspaces()->where('id', '=', 1)->account()->account_url()->select('url')->get();
and:
$account_urls = account::where('workspace_id', '=', '1')->account_url()->select('url')->get();
Only when I do it like this:
$account_urls = account::find(1)->account_url()->select('url')->get();
But then I get only 1 url, but when I replase find(1) for all() I get an error?
Is there someone who can help me with this?
Tanks,

Your relations are wrong, change them to:
// User
public function account()
{
return $this->hasManyThrough('Account', 'Workspace', 'user_id', 'workspace_id');
}
// Account
// use camelCase for relations
public function accountUrl()
{
// I assume you have account_url_id on accounts table
// If it's opposite, then use hasOne
return $this->belongsTo('AcountUrl', 'account_url_id', 'id');
}
// AccountUrl (use camelCase)
public function account()
{
// if above is hasOne, then here belongsTo instead.
return $this->hasOne('account', 'account_url_id', 'id');
}
Now, fetching models:
// this part is .. amazing ;)
user::find( Auth::user()->id )->first();
// it does this:
Auth::user()->id // fetch user and get his id
user::find( .. ) // fetch user with given id, you have this user already above...
->first() // fetch first row from users table (not the one with id provided before)
so you want:
$account_urls = Auth::user()->workspaces()
->where('id', '=', 1)->first() // first fetches the result
// or simply
// ->find(1)
->accounts()->first()->accountUrl()
->pluck('url'); // this does 'SELECT url' and returns only this field instead of model
Just remember that:
$user->workspaces
$workspace->accounts
these are collections, so you can't call anything of the model on them, you need to get single model first.
