Laravel 5.4 relationship - php

Question

Hi I need to display users items from table name Items.
I have 3 models.
User model:
public function userItem()
{
return $this->hasMany('App\UserItem', 'item_id');
}
UserItem model:
public function user()
{
return $this->belongsTo('App\User', 'user_id');
}
What to write to Item Model to make this relationship successful. So I could display items from items table.
If I now do this:
I get info from user_items table from DB.
when I do this #foreach(Auth::user()->userItem as $item) I get this:
Column not found: 1054 Unknown column 'user_items.user_items' in
'where clause'

Answer 1

I think you want to use many to many relation
you have 2 models User and Item
and 3 tables : -users -items -user_items
User Model should be like this:
public function userItem()
{
return $this->belongsToMany('App\Item','user_items','user_id','item_id');
}
and Item Model:
public function user()
{
return $this->belongsToMany('App\User','user_items','item_id','user_id');
}
and you need a table that you named it user_items
and you dont need to define userItem model you can remove relations in this model
in your blade use this code:
#foreach(Auth::user()->userItem as $item)

Answer 2

You are exhibiting a many-to-many relatioship, and yet using methods for one-to-many relationships. For a many to many relationship, use the following code in your models:
//user model:
public function userItem()
{
return $this->hasMany('App\UserItem', 'user_items', 'user_id', 'item_id');
}
//userItem Model:
public function user()
{
return $this->hasMany('App\User', 'user_items', 'item_id', 'user_id');
}
For a many-to-many relationship, you need a hasMany method on both your models.
For information on the parameters to the hasMany method as well as other information on many-to-many relationships, please read the documentation on many-to-many relationships: https://laravel.com/docs/5.4/eloquent-relationships#many-to-many
Hope this helps.
