I'm sorry, I don't even know how to ask for what I need...
User:
id
MyItem:
id
item_id
user_id
Item:
id
How to get $user->items()?
I guess hasManyThrough() won't help here.
Thank your very much for help.
If you have defined your relationship and have items relation in your User model, you can get them using:
foreach ($user->items as $item) {
echo $item->id;
}
As it's many to many relationship, in class User you need to define your relationship this way:
public function items() {
return $this->belongsToMany('Item');
}
and in Item class this way:
public function users() {
return $this->belongsToMany('User');
}
And your pivot_table should have here name item_user. If it's not, pass your table name as 2nd argument to belongsToMany method
I don't know what you want exactly but
i think you need user relative more information
if you want user relative in formation
so please try this
you get all information about user
$users = User::all();

Hello as the title says I'm not sure why my code is not showing the "First Name" for a user but it shows the ID only I have tried to do a lot of different methods to solve this but I'm rather a beginner in laravel so I thought It would be best if I asked for help by now
To explain a little the field "recieverID" is a foreign key of the table Users that shows the ID of the users
So here is the model named "Remark"
class Remark extends Model
{
protected $guarded =[];
public function user(){
return $this->belongsTo(User::class);
}
}
This is the Remark Controller
public function index()
{
if(Auth::guard('admin')->check())
{
$users = User::all();
$remarks = Remark::latest()->get();
return view('admin.remark.index', compact('users'),compact('remarks'));
}
It has more code under it but I only need it for this part, I added the $users and compact users because I tried to add 2 foreach loops on the view to see how it looks but it didn't quite work as i thought it might
This is the view I want to show the Name instead of the ID
#foreach($remarks as $remark)
<tr>
<td>{{$remark->recieverID->user->first_name}}</td>
<td>{{$remark->title}}</td>
<td>{{$remark->subject}}</td>
<td>{{$remark->message}}</td>
<td>{{$remark->sender}}</td>
</tr>
#endforeach
Thank you for your time
First of all, you need to change your relationship as below. If you don't pass foreign key then it assumes that you have foreign key as(user_id) in the table. but you have recieverID in the table. So, you need to define it.
public function user(){
return $this->belongsTo(User::class,'recieverID','id');
}
Now you can add it blade file.
<td>{{$remark->user->first_name}}</td>
I wanna get the class name of a user via the user ID. When I input the ID of a user so I will wanna get the class name. I have three tables such as users table, classes table, and class_users table. The class_users table is born from two users table and classes table.
A users table has an id, name, email, password.
A classes table has an id, class_code, class_name.
A class_users table has an id, class_id, user_id
And this problem relates to Eloquent Relationships.
Thank you for help.
My Route:
Route::get('/find_classes/{id}','StudentController#find_classes');
My Controller function:
public function find_classes($id)
{
$users = User::find($id);
foreach($users->classes as $class)
{
echo $class->name . '<br';
dd($class);
}
}
My User Model:
public function classes()
{
return $this->belongsTo('App\Classes','class_users','user_id','class_id');
}
Looks like you might have the wrong relationship set up on your User model. You have a one to many set up, but your DB is setup to handle a many to many. I suggest you change your User model relationship:
public function classes()
{
return $this->belongsToMany('App\Classes');
}
Note, you may need to name the FK on that relation, as I see you have class_id on the table, but your actual class is named 'Classes'. Check through your relationships to ensure this is explicit on the FK where it doesn't follow Laravel convention exactly.
With this relationship, your foreach loop should work. It would be a good idea for efficiency, as mare96 noted, to eager load the classes on the $users collection when you query:
$users = User::with('classes')->find($id);
Right now I have the following models structure,
Country -> State -> City -> Student
And the Student model includes first_name and last_name.
So, I want countries to by filtered by giving student's first name. Like if I give John then I want list of countries which has students whose first name is John.
I was trying something like this,
I added a method called Students() in Country model and returning Student instances from that method. But now I stuck to find out how to filter countries.
Thanks in anticipation.
I came across a similar question recently and I came with the following solution myself. Probably, there are easier ways, but this will get you going for now, I guess.
First we query all the users with first_name == John, as you described, and we limit the query to output only the ID's.
$users = User::where('first_name', 'John')->get()->pluck('id');
We then cross-compare this with the result of Students() from the country model. As I don't know what you're querying for to get the country that you want, I'll just take the Netherlands as an example — that's where I'm from.
$users = Country::where('name', 'the Netherlands')->students()->whereIn('id', $users)->get();
For this to work, you must make sure that within the Students()-function in your model, the get() is left out.
Final 'result':
$users = User::where('first_name', 'John')->get()->pluck('id');
$users = Country::where('name', 'the Netherlands')->students()->whereIn('id', $users)->get();
in the Student Model create this:
public function city()
{
return $this->belongsTo(City::class,'city_id', 'id');
}
and in the City Model create this:
public function state()
{
return $this->belongsTo(State::class,'state_id', 'id');
}
Finally in the State Model:
public function country()
{
return $this->belongsTo(Country::class,'country_id', 'id');
}
For example if you made things like that in controller:
$students = Student::where('name', 'John')->get();
in the view:
#foreach($students as $student)
$student->city->state->country->country_name;
#endforeach
You can access like that.
If you have setup the model and relationship properly then you need to call them using in with function
$students = Student::where('name','John')->with('city.state.country')->get();
Loop through the $students
#foreach($students as $student)
{{ $student->city->state->country }}
#endif
I'm trying to get all the properties, in a watchlist(s) where the list has a user id.
The relationship is set up as follows.
Each watchlist is related to a user id. Each Property has a watchlist id.
I need all properties, in all the watchlists belonging to that user.
The watchlist gets the user_id automatically upon creation.
Here are my models
Watchlist
public function properties(){
return $this->hasMany('App\WatchedProperties');
}
public function user(){
return $this->belongsTo('App\User');
}
WatchedProperties
public function watchlist(){
return $this->belongsTo('App\Watchlist');
}
Query
Gets all books in every list disregarding user ids and list ids
$Watchlists = WatchedBooks::all();
Currently gets all books regardless of userid.
I need all books in all of the user's lists.
A user could have multiple lists
List A
List B
So something like
All books from all lists where the list id is related to user id.
This is what the Watchlist DB looks like
WatchlistDB
This is what the WatchedBooks DB looks like
Books in watchlist
Laravel has a beautiful solution for this: you can add a ->hasManyThrough relation to the user model. You can find more information about this type of relation in the Laravel documentation about Eloquent relationships.
The user model will look like this:
class User extends Model {
[...]
public function watchedBooks()
return $this->hasManyThrough('App\WatchedBook', 'App\Watchlist');
}
[...]
}
Then you can get all the WatchedBooks, associated with the user, using
$user->watchedBooks;
or
$user->watchedBooks()->yourBuilderQueryHere()->get();
whereHas allows you to query in relationships. More information on this can be found at https://laravel.com/docs/5.6/eloquent-relationships#querying-relationship-existence
$Watchlists = WatchedBooks::whereHas('watchlist', function($query) use ($user_id){
$query->where('user_id', $user_id)
})->get();
The script above gets all WatchedBooks that are associated with a Watchlist that is owned by a user ($user_id).
I have a many to many Laravel Relationship Many Users have Many Roles
I know that I can do User::find(1)->roles()->get() to get all roles with an ID of 1 for a User but this requires me to know the ID of the role as oppossed to just its names
What sort of eloquent query could I put in my user Repository to do something like
public function getAllUsersWithRole($roleType){
//Query goes here
}
Where $roleType is the name of the Role. So I need to look up the ID of the role based on hte name and then return users that have that role ID in the pivot table
does this look like what you want:
public function getAllUsersWithRole($roleType){
$role= Role::where('name', $roleType)->first();
$users= $role->users;
return $users;
}
If you have correct relation definitions in your Eloquent models you should be able to get the users by the role name this way:
$roleType = 'YourRoleName';
$users = Role::whereType($roleType)->first()->users;
Grab the users, then get the roles for all the users.
public function getAllUsersWithRole($roleType){
$users = User::where('role_type', '=', $roleType)->get();
$roles = $users->roles()->get();
return $roles;
}
