How to List all rows from a table (agendas) in my DB where records are saved by the connected user.I'm using default Auth from Laravel.
public function index ($id = null)
{
$agendas = Agenda::where('id', Auth::user()->id)->get();
$users = User::all();
return view('admin.agendas.index', compact('agendas','users','id'));
}
My controller here.
Need help
Assuming
agendas table (containing records for Agenda model) has a column user_id which references the id column on users table
User hasMany Agenda
Agenda belongTo User
class User extends Model
{
public function agendas()
{
return $this->hasMany(Agenda::class);
}
//... rest of class code
}
class Agenda extends Model
{
public function user()
{
return $this->belongsTo(User::class);
}
//... rest of class code
}
public function index($id = null)
{
$user = User::with('agendas')->findOrFail(auth()->id());
return view('admin.agendas.index', [
'user' => $user,
'agendas' => $user->agendas,
'id' => $id
]);
}
Your User model should have a relationship:
public function agendas()
{
return $this->hasMany(Agenda::class);
}
In your controller, you could then simplify the use as such:
public function index (Request $request, $id = null)
{
$agendas = $request->user()->agendas;
$users = User::all();
return view('admin.agendas.index', compact('agendas','users','id'));
}
if you wanna get data related to another data , you have to join those tables together by a field. in this case i guess you have a column in Agenda table named 'user_id'.
you have two way :
join tables in your Model.
search in Agenda table in your controller
if you want to use joining your tables from model :
// in App\User.php
...
class User ...{
...
public function Agenda(){
return $this->hasMany(Agenda::class);
}
...
}
...
then you can access to all of "Agenda" from everywhere like this :
Auth()->user()->agenda
if you want to search in table from your controller you can do :
Agenda::where('id', Auth::user()->id)

I am facing a super weird issue.
I have 3 tables and their equivalent model:
App\User
public function company() {
return $this->morphTo();
}
App\Supplier
public function user() {
return $this->morphOne(User::class, 'company');
}
App\Company
public function users() {
return $this->morphMany(User::class, 'company');
}
For some reason the relationship on App\Supplier does not work, but all the other works normal, I can even get the supplier if I have the user:
$supplier = \App\Supplier::find(1);
$company = \App\Company::find(2);
$supplieruser = \App\User::find(1);
$supplier->user //THIS RETURN NULL
$company->users //return collection of users normally
$suppplieruser->company //returns an instance of supplier model
I have tried, changing the name of the relationship and nothing.
Any idea?
In case someone find this in the future... the relationship was not working because I had in my AppServiceProvider the following:
Relation::morphMap([
.....
'supplier_to_supplier' => 'App\Supplier',
.....
]);
It seems that registering it here will affect all the morphs from that model.
Hi I am trying to create a record base from ID of an order transaction.
I have here the ORDERS, CAMPANIES and CURRENCIES models.
Now I want the ORDER to get the ID from a URL Parameter, and then the companies should grab the company_id from Orders same with currency, I want to grab the currency_id from orders.
Here's what I came up so far:
public function create($order_id)
{
$order = Orders::find($order_id)->where('id', '=', $order_id)->get();
$company = Companies::where('id', '=', $order['company_id'])->get();
$currency = Currencies::where('id', '=', $order['company_id'])->get();
$banks = Banks::all('name','acronym','id')->get();
return view('orderPayments.create', compact('order'))
->with('company', $company)
->with('currency', $currency)
->with('banks', $banks);
}
currencies model
public function orderPayments()
{
return $this->hasMany('App\Orderpayments', 'id','currency_id');
}
Companies Model
public function orderPayments()
{
return $this->hasMany('App\Orderpayments', 'id','company_id');
}
Order Payments Model
public function company()
{
return $this->hasOne('App\Companies', 'id','company_id');
}
public function currency()
{
return $this->hasOne('App\Currencies', 'id', 'currency_id');
}
public function bank()
{
return $this->hasOne('App\Bank', 'id', 'currency_id');
}
How can I achieve it? thank you so much in advance!
UPDATE
I just applied #sandy's answer. I checked if the $order has a content so I echod the $order by doing this, {{ $order }} The return value is ok.
but when I calling the other attributes like $order->grandtotal, or $order->companies->comp_name the error is
If your relationship between your models is a One To Many relationship you should use belongsTo in your relations like this:
OrderPayment Model
public function company()
{
return $this->belongsTo('App\Companies','company_id');
}
public function currency()
{
return $this->belongsTo('App\Currencies','currency_id');
}
public function bank()
{
return $this->belongsTo('App\Bank', 'currency_id');
}
Also, the second parameter on the function should be your foreign key.
Answering your question:
If you want to access the relations of a given Order you could do this:
$order = Order::find($order_id);
$order->company; // this will return the company
$order->currency; // this will return the currency
If you want to display in your view:
{{$order->company->anyCompanyAttribute}}
Note:
You should name your models in SINGULAR like Currency, Company. Not in plural.
try like this
$order = Orders::with(['company','currency'])->where('id', '=', $order_id)->get();
I'm learning Laravel, and really OOP in general. I've followed several YouTube tutorial series, that teach you to create a blog in Laravel.
I'm building a task app for a brewery, and I'm trying to define the relationships between the users and the tasks. So I have two models: User.php and Task.php. I had no problem defining the user in a hasMany tasks relationship, and reciprocally, a task belongsTo a user. Where I'm confused is that I'd like to also have a user belong to the task as well. I have two MySQL columns, one with the heading of "user_id" and the other with "user_assigned_id". What I want is that a user has many tasks, but a task also has one assigned user, the idea being that the user that created the task might assign the task to another user. I've found several tutorials on creating relationships between three models, such as a user owning several messages, but only having one address, so I figured that I could just treat two models as if they were three models and connected the User model back to the Task model in a hasOne relationship, but I'm having a really hard time passing that through to the Controller and View.
Here is the relevant code in each file:
User.php
public function tasks()
{
return $this->hasMany('App\Task');
}
Task.php
public function user()
{
return $this->belongsTo('App\User');
}
// Added an user_assigned_id relationship
public function user_assigned()
{
return $this->hasOne('App\User', 'name', 'user_assigned_id');
}
DashboardController.php
public function index()
{
$user_id = auth()->user()->id;
$now = Carbon::now();
$tasks_assigned = Task::orderBy('date', 'asc')->whereDate('date', '>=', $now)->where('user_assigned_id', '=', $user_id)->user_assigned()->where('name', '=', 1)->get();
$tasks_created = Task::orderBy('date', 'asc')->whereDate('date', '>=', $now)->where('user_id', '=', $user_id)->get();
return view('dashboard')->with('tasks_assigned', $tasks_assigned)->with('tasks_created', $tasks_created);
}
I've gotten a bit turned around in the Controller, so I'm not sure if I messed something up there. Basically, I'm getting results from tasks owned by the logged in user, but not assigned to the logged in user.
You can just add a second relationship defined on your Task.php Model and assign a different agent based on user_assigned_id. You can manipulate it as expected via Eloquent.
Task.php
public function user() {
return $this->belongsTo('App\User');
}
public function assignedUser() {
return $this->belongsTo('App\User', 'user_assigned_id');
}
Then on DashboardController.php
$tasks_assigned = Task::orderBy('date', 'asc')->whereDate('date', '>=', $now)->where('user_assigned_id', '=', $user_id)->get();
should work
public function user()
{
return $this->belongsTo('App\User');
}
// Added an user_assigned_id relationship
public function assignee()
{
return $this->belongsTo('App\User', 'user_assigned_id');
}
The relationship is still a belongsTo, you just need to provide the column where the foreign key is held.
Other files:
User.php
public function ownedTasks()
{
return $this->hasMany('App\Task');
}
public function assignedTasks()
{
return $this->hasMany('App\Task', 'user_assigned_id');
}
Dashboard Controller
public function index()
{
$now = Carbon::now();
$tasks_assigned = Auth::user()->assignedTasks()->where('date', '>=', $now)->get();
$tasks_created = Auth::user()->ownedTasks()->where('date', '>=', $now)->get();
return view('dashboard')->with(compact('tasks_assigned', 'tasks_created'));
}
I don't think this is possible in Laravel, but I am still going to ask it ;)
I have a Group model that has a pivot relation(via group_user) to User. I have a group controller where this is the index method:
public function index(Request $request)
{
return $request->user()->groups;
}
groups in User is a belongsToMany relation. It will load all groups that have a relation to a user. This will also load the pivot table in the pivot relation.
But now I want to get a single group, this is the controller to get a group with pivot relation:
public function show($id, Request $request)
{
$group = $request->user()->groups()->findOrFail($id);
$this->authorize('view', $group); // Authorization....
return $group;
}
But I would like to use Implicit binding like this:
public function show(Group $group)
{
$this->authorize('view', $group);
return $group;
}
But it won't load the pivot table because I don't get it via the user...
So I should get the group via the user. But how can I do this with implicit binding?
When this isn't possible: How can I load a pivot relation when I already have the group model?
public function show(Group $group, Request $request)
{
// Load the pivot relation here in $group by using the user in $request->user()?
$this->authorize('view', $group);
return $group;
}
Put this is the RouteServiceProvider:
Route::bind('group', function ($value) {
if (auth()->check()) {
return auth()->user()->groups()->findOrFail($value);
} else {
abort(404);
}
});
The view policy isn't even needed this way because the group is from the groups relation:
public function show(Group $group)
{
return $group;
}
