I have two tables, concessionaire and bills. concessionaire has many bills but I only want to get the latest bill for previous bill purpose. Can you help me how can I do it?
Here is my template
#foreach($dataUser as $User)
<tr class="item{{$User->id}}">
<td>{{$User->id}}</td>
<td>{{$User->bill->newrec}}</td>
</tr>
#endforeach
and my model is
public function bill()
{
return $this->hasMany('App\Monthlybill', 'meternum', 'meternum');
}
and in my controller
$dataUser = Concessionaire::with('user','rate', 'bill')
->get();
//dd($dataUser);
return view('reader.concessionaires',compact('dataUser'));
Right now that is my code but I do not know how can I get the latest bill record.
Use last helper
{{$User->bill->last()}}//this will give you the last items in collection
Try with below code:
{{$User->bill->last()->newrec}}
Thanks!

I have two Table names are User and Role Table. I have set manyTomany relations between them using pivot table name Role_User in Laravel Eloquent.
Now, I want to show both table data in together a view using Eloquent Relationship.(e.g. I want to show in my view a user from users table contain which role in roles table )
Here, is my eloquent relations.
public function roles()
{
return $this->belongsToMany('App\Role');
}
public function users()
{
return $this->belongsToMany('App\User');
}
My, Eloquent Relationship Query.
$users=User::with('roles')->get();
return view('admin',compact('users'));
I'm try in my View.
#foreach($users as $user)
<tr>
<td>{{$user->name}}</td>
<td>{{$user->email}}</td>
<td>{{$user->roles->name}}</td>
<td></td>
</tr>
#endforeach
When you call $user->roles, you get a collection of the roles back. So if you want to display them all in a single string, all you have to do is implode the collection on that string:
<td>{{$user->roles->implode('name', ', ')}}</td>
Your $user->rules is instance of Collection of Role model. You can use one more foreach:
#foreach($users as $user)
//do something with user
#foreach($user->roles as $role)
{{$role->name}}
#endforeach
#endforeach
This will work in Laravel 5.0 and above
If we have two Model User and Mark. Then Inside the User Model make a function for relation with Mark. Example
public function marks()
{
return $this->hasMany('App\Models\Mark');
}
So, If you want to display the User name will all his marks. Then inside the controller perform following way.
public function getUserMarks(){
$result = User::select('email', 'name')->where('email', 'usermail#example.com')->with(['marks'])->get();
return view('welcome', compact('results'));
}
I'm working on updating a laravel blade template to insert some database info into an html table. IN order to do this, I'm having to add new data to the controller for this blade and that's where I'm having some troubles.
I'm still trying to understand more with laravel, so I'm thinking my syntax or methods of creating this data are incorrect but I just can't put my finger on it right now.
In my function below, the $calls_allowed portion was already existing and it works on the page currently. I created the $contact_events portion of the function and that's where my problem is.
IN my view, I created a foreach loop and if statement around the html table in question. The table loads, but it's empty even though there are records in the database for the dealer.
I'm trying to say
if $dealer-> id matches contact_events.dealer_num, load all records for that dealer
contact_events is the table and dealer_num is the column I'm matching, then I'm trying to load the columns from that table (updated_at,method,notes) into the html table.
The affected code is below. The view/route/controller work, it's just this function I'm creating that isn't loading data. Any help is much appreciated.
Controller code:
public function show($id)
{
$d = Dealer::find($id);
if(!$d){
\Session::flash('warning_message', 'Sorry that resource can not be found.');
return redirect()->route('account.dealer.index');
}
$calls_allowed = DB::table('dealers.dealers')->
where('dealer_num', $id)->
pluck('calls_allowed');
$contact_events = DB::table('dealers.contact_events')->
where('dealer_num', $id)->
pluck('updated_at', 'method', 'notes');
if(!empty($calls_allowed)){
$d->calls_allowed = $calls_allowed[0];
} else {
$d->calls_allowed = null;
}
return view('Account.Dealer.show')->with('dealer', $d);
}
View code:
<thead>
<tr>
<th>Contacted Date</th>
<th>Type of Contact</th>
<th>Call Notes</th>
</tr>
</thead>
#foreach($dealer->contact_events as $events)
#if($events->dealer_num = $dealer->id)
<tbody>
<tr>
<td>{{$events->updated_at}}</td>
<td>{{$events->method}}</td>
<td>{{$events->notes}}</td>
</tr>
</tbody>
#endif
#endForeach
It looks like you are not assigning the data to the object after retrieving from database.
$contact_events = DB::table('dealers.contact_events')->
where('dealer_num', $id)->
pluck('updated_at', 'method', 'notes');
// add this
$d->contact_events = $contact_events;
This seems like a perfect time to use the power of Laravel's Eloquent ORM...
Check out the with and has in the Laravel docs
This will require some finessing based on your needs, but it will be something like this:
$d = Dealer::where('id', '=', $id)
->with('contact_events')->first();
This uses Eloquent to get all of the contact_events that belong to the dealer with the $id.
Then you can do something like this
note: this assumes that calls_allowed is a record on the dealer table. if I misunderstood that, you can still run than you can include that just as you have it.
#if(!is_null($dealer->calls_allowed)
#foreach($dealer->contact_events as $events)
<tbody>
<tr>
<td>{{$events->updated_at}}</td>
<td>{{$events->method}}</td>
<td>{{$events->notes}}</td>
</tr>
</tbody>
#endForeach
#endif
I have relations like this
User->hasMany->reviews
Review->belongsTo->user
Review->hasMany->ReviewAnswer
ReviewAnswer->belongsTo->Review
Now I try to display answers for specific review. My reviewAnswer table looks like:
Id, review ID, text
But the problem is when I do that:
#foreach($user->reviews as $data)
#foreach($data->reviewAnswers->where('review_id', $data->id) as $answer)
{{$answer->text}}
#endforeach
#endforeach
Then reviews displays okay, but I get the same answers for every review. How to repair that?
Make sure to check if all the relationships are correct. In this example, I assume that your models are stored in your app folder.
First, your User model should have reviews
public function reviews() {
return $this->hasMany("App\Review", "user_id", "id");
}
Next, set up your Review model to have answers
public function answers() {
return $this->hasMany("App\ReviewAnswer", "review_id", "id");
}
Then this is how you'll get all users with their respective reviews and answers
$users = User::with("reviews.answers")->get();
Finally, peform the loop in your view
#foreach($users as $user)
#foreach($user->reviews as $review)
#foreach($review->answers as $answer)
#endforeach
#endforeach
#endforeach
Try using the hasManyThrough() option which the eloquent models provide you.
Link: Laravel Eloquent Relations
This means in your case you would add:
class User extends Model {
public function reviewAnswers(
return $this->hasManyThrough(ReviewAnswer::class,Review::class);
)
}
and then simply access it in blade as:
#foreach($user->reviewAnswers() as $reviewAnswer) {
{{$reviewAnswer->text}}
}
I am using a hasMany in my Model class to retrive the clients notes, how ever i want to order these notes by the latest date created in laravel blade template.
My code is below and im getting an error on this.
Please advice me..
#foreach($clients->notes->orderBy('created_at', 'desc') as $note)
<table class="table table-bordered">
<tr>
<td class="col-xs-2 col-md-2"><b>Created On:</b> {{ date('d/m/y', strtotime($note->created_at)) }} <b>#</b> {{ date('g:i A', strtotime($note->created_at)) }} </td>
<td class="col-xs-14 col-md-12">{{ $note->notes }}</td>
</tr>
</table>
#endforeach
Guessing, because you haven't told us what error you're getting, but:
$clients->notes is an already-fetched collection of results. $clients->notes() is a query builder that you can apply further logic like ordering or additional criteria to.
You likely want:
$clients->notes()->orderBy('created_at', 'desc')->get()
but you should do that in the controller and pass it to the view instead of having the query directly in the Blade template.
(You can alternatively use Laravel's collection functions on $clients->notes, including the sortBy() function).
Data must be ordered within controller or models. If you have used hasMany validation in model you can do as mentioned below
In model write association
public function notes()
{
return $this->hasMany('Note')->orderBy('created_at', 'desc');
}
In your controller function associate client with notes like this
$clients = Client::with('notes')->get();
Hope you get your answer
What is the Correct Way to retrieve a column value based on certain select filter on a Model variable availed by compact method inside the blade. (Larevl 5)
I read that Its a bad practice to query database staright from views, and hence i followed the convention to avail the required data with compact method to view
However, In a scenario where I need to query another table based on certain column value returned in foreach loop inside a blade from first table, I am unable to figure out correct Approach
Example: I have two Models User & Group
Schema User Table
id,name,email,group_id
Scheme Group Table
id,groupname
Here is the UserController -> compact method
$users = \App\User::all(array('id','name','email','group_id'));
$groups = \App\Group::all(array('id','group_name'));
return view('user.index', compact('users','groups'));
Here how the blade needs them
#foreach ($users as $user)
<tr>
<th>{{$user->id}}</th>
<th>{{$user->name}}</th>
<th>{{$user->email}}</th>
<th>
<!-- Here i need to run something like
select group_name from group where id = $user->id -->
{{$groups->where('id','=',$user->group_id) }}
</th>
<th>Actions</th>
</tr>
#endforeach
I know this returns an array , and I'have two questions here
How to get the value for group_name column from the Group Model based on group.id = $user->id in a foreach loop
Since Its a bad practice to query db from blade, how would I avail the values from a model by passing data via compact from controller to blade, when the where clause parameter's are not yet known.
Edit 1:
I modified the last group query as
<th>#if($groups->where('id','=',$user->group_id))
#foreach($groups as $group)
{{$group->group_name}}
#endforeach
#endif
</th>
And I was able to get the result, however this again isn't a correct approach , so question remain unanswered
In User model
public function group()
{
return $this->belongsTo('App\Group');
}
In Group model
public function users()
{
return $this->hasMany('App\User');
}
In your controller
$users = \App\User::with('group')->get();
return view('user.index', compact('users'));
Now in your view you can do
$user->group->name;
I appreciate the fact that you know "It's bad practice to query from view".
Why don't you use join.
DB::table('users')->join('groups', 'users.group_id', '=', 'groups.id')->get();
Then pass the result to your view and loop through it.
Here you will have each user data associated with his group data.
