Laravel 5 Eloquent ORM multi relation - php

Question

I'm totally new in Laravel, and I'm trying to create relations between models. My tables are:
patch
id
title
area
id
location
area_patch
id
patch_id
area_id
user_area_patch
id
area_patch_id
plant_id
plant_date
User model, "patchs" function should execute something like this:
SELECT
p.id, p.title, up.plant_id, up.plant_date
FROM
rsst_farming_patch p
JOIN rsst_farming_area_patch pp,
rsst_farming_user_patch up ON pp.id = up.area_patch_id AND p.id = pp.patch_id WHERE up.user_id = 1
my models:
class User extends Model {
public function patchs() {
//return user patchs
}
}
class Patch extends Model {
public function area() {
//return area that this patch belongs to
}
}
class Area extends Model {
public function patchs() {
//return available patchs
}
}
can some one make an example of this? I would like to study it. I was messing around with User model, belongsToMany and hasManyThrough, but no luck.

You may need to modify your table structure slightly to make this happen.
I see in youruser_area_patch table you are trying to link the user, area, and patches together. That's not typically how I've done it in laravel. Normally you use a pivot table to link two items together. So let me suggest something like this:
Does a patch belong to a single user? If so you should add a user_id to the patch table.
patch
id
user_id
area_id
title
Can an a Patch be in multiple areas? I kind of doubt it, so I'd add an area_id as well.
class User extends Model {
public function patchs() {
return $this->hasMany('App/Patch', 'user_id');
}
}
class Patch extends Model {
public function area() {
return $this->belongsTo('App\Area', 'area_id');
}
}
class Area extends Model {
public function patchs() {
return $this->hasMany('App\Patch', 'patch_id');
}
}
Then you can start referencing your patchs like:
$patchs = User::find(1)->patchs()
or the area that a patch belongs to by
Patch::find(1)->area()
and all the patchs in an area by
Area::find(1)->patchs()
Does this help?
