I'm using Laravel 5.2 and I want to update my database records. Before carrying out the update, I want to show all affected data to the user as in the image below:
Instead of showing Category ID, I want to show the Category Name.
I've made the relationship between category and subcategory.
I have a AdminController controller through which I'm passing data to the view.
Below is the content of my AdminController controller:
public function getUpdateSubcategory()
{
$subcatgry = subcategory::all();
return view('admin/UpdateSubcategory', ['subcategory' => $subcatgry]);
}
This is my view file:
![Controller Image retrieving and passing value to view][3]
What am I doing wrong?
Write it as..
#foreach($subcategory as $subcategories)
<tr>
<td> Edit </td>
<td> {{ $subcategories->subcategory_name }} </td>
<td> {{ $subcategories->category_id}} </td>
</tr>
#endforeach
You can not use same variable name in the iterating foreach loop.. So just changed the name of the second variable.

im trying to get the latest data on database, im using this on my views :
#foreach ($shows as $s)
<tbody>
<tr>
<th scope="row">{{$loop->iteration}}</th>
<td>{{$s->nama}}</td>
<td>{{$s->umur}}</td>
<td>{{$s->alamat}}</td>
<td>{{$s->nama_ortu}}</td>
<td>{{$s->posyandu}}</td>
<td>{{$s->result}}</td>
</tr>
</tbody>
#endforeach
and on controller :
public function showresultpasien()
{
$shows = DB::table('pasiens')->orderBy('id', 'DESC')->first();
return view('result', compact('shows'));
}
did i doin something wrong ?
The name of the function in the model cannot be the same as the name of a field in your table. Also in my case the column names do not follow the laravel/eloquent nomenclature so another parameter is added to belongsTo with the field name
I have two tables with two models and make a reactionship to can get the field_name from the first table :-
First Model:
class KpcField extends Model
{
public function concession(){
return $this->hasMany(Concessions::class);
}
}
Second Model :
class Concessions extends Model
{
public function kpcField(){
return $this->belongsTo(KpcField::class);
}
}
And trying to retreive the field_name in concession view but it showed (Trying to get property field_name of non-object)
Using the foreach to show the data in table :
#foreach ($show_concessions as $show_concession)
<td> {{ $show_concession->kpcField->field_name}} </td>
#endforeach
You can Try This :
#foreach ($show_concessions as $show_concession)
#foreach ($show_concession->kpcField as $item)
<td> {{ $item->field_name}} </td>
#endforeach
#endforeach
I've looked at other questions that have answered this same error and I understand I have a property that cannot be defined but not sure how to make it defined. First time using Many-to-Many relationship so I'm assuming this is the issue.
Project Table
id
company
stage
status
date_started
date_finished
timestamps
Employee Table
id
name
department
timestamps
Employee_Project Table
id
employee_id
project_id
In both models, I have belongsToMany and for the show function in the ProjectController, I have:
$projects = Project::find($id);
In the view, I want to show company name ($projects->company) and the employees on that project with their respective departments. These do not work:
$projects->employees->name
$projects->employees->department
How do I access these properties?
--Update--
Jeff's answer works but I set up a table like
<thead><th>PM</th><th>AM</th></thead>
<tbody><td>#if($employee->department == 'Project Manager'){{ $employee->name }}</td>
<td>#else($employee->department == 'Account Manager'){{ $employee->name }}</td></tbody>#endif
and this does not work to show the correct employees in their respective sections. Any ideas how to fix this?
Your problem is that $project->employees is a collection, not an individual instance of an employee. You will need to iterate over the collection in order to access each individual employee's name:
foreach($project->employees as $employee) {
echo $employee->name;
echo $employee->department;
}
Update
It looks like you may need to restructure as below, I think you probably want the entire if construct to be within the same table cell, though I could be wrong:
<tbody>
#foreach($project->employees as $employee)
<tr>
<td>
#if($employee->department == 'Project Manager')
{{ $employee->name }}
#elseif($employee->department == 'Account Manager')
{{ $employee->department }}
#else
<!-- What about non project/account managers? -->
#endif
</td>
</tr>
#endforeach
</tbody>
I could be totally wrong, and maybe you want account managers and project managers in different columns:
<tr>
<td>
#if($employee->department == 'Project Manager')
{{ $employee->name }}
#endif
</td>
<td>
#if($employee->department == 'Account Manager')
{{ $employee->name }}
#endif
</td>
</tr>
Be sure to take a look at the documentation on Blade if statements.
Update 2
If you want to order how the related entities are coming back, you can do something like this (assuming you want the employees ordered by their department:
$project->employees()->orderBy('department', 'DESC')->get();
Notice you're no longer accessing the property, you're calling the relation method employees() so that you can modify the query prior to it being executed.
Here's a link to the documentation on ordering queries, and there is also another StackOverflow question on it.
So I figured out how to show the correct person to show up under their respective departments in the table and I wanted to share.
Thanks to #jeff-lambert I added the foreach loop but I had added to the entire row like in his first update. This did not work because the employees were not showing up in their respective departments. For example, account managers were showing up under the project manager . To resolve this, I had to add a foreach loop to each .
<td>
#foreach($projects->employees as $employee)
#if($employee->department == 'Project Manager')
{{ $employee->name }}
#endif
#endforeach
</td>
Hope this helps explain it.
First time to try laravel eloquent relatioinstip
I know it's really simple but I am getting this error don't know what's wrong with it
I have 2 tables in data base, news and news_image
in database
Tables:
news
id | header | details
news_image
id | image | news_id
And have 2 models News , newsImage
newsImage model :
class newsImage extends Eloquant {
protected $table = 'news_image';
public function news()
{
return $this->belongsTo('News');
}
}
News model
class News extends Eloquent
{
protected $table = 'news';
public $timestamps = false;
public function image()
{
return $this->hasMany('newsImage');
}
}
The view:
foreach($news as $new)
<tr>
<td> {{$new->id}} </td>
<td> {{ $new->header}}</td>
<td> {{ $new->details }}</td>
</td> {{$new->news->image}}</td>
</tr>
when I run this it's get error :
Trying to get property of non-object (View: /var/www/html/clinics/app/views/news/index.blade.php)
Any ideas on what could be causing this error?
First, assuming what you are passing to your view is an array or Collection of News objects, you should probably be using $new->image to access the News Item relation. By defining the function image() in your News model, you can access the relation with either the ->image or ->image() calls. In either case, what you need to call is probably
$new->image->first()->image
To break that down:
->image gets the Collection of NewsImage relations
->first() gets the first item in the Collection
->image (the secone one) gets the image field from that NewsImage
If the Collection has more than one item, you can instead loop over it to get all of the images as shown in the other answer.
There are a couple things I would change:
In your News model, change the relationship from "image" to "images" since it's a one to many relationship. It just keeps your code clean.
Your foreach loop in your view should loop through all the news models, but remember that each news model has multiple images, so you should have another loop inside your existing loop to display the images, i.e. foreach ($new->images as $image)
#foreach ($news as $new)
<tr>
<td> {{$new->id}} </td>
<td> {{ $new->header}}</td>
<td> {{ $new->details }}</td>
<td>
#foreach ($new->images as $image)
{{ $image->image }}
#endforeach
</td>
</tr>
#endforeach
I have 3 table as mentioned below.
Table 1(user):
id username password Name Age
Table 2(tasks):
id task_name description
Table 3(logs)
id user_id task_id date hours
Table Relationships:
user has_many logs
task has_many logs
logs belongs_to user
logs belongs_to task
what i am trying to achieve is to get the logs with the user Name, task Name, date and hours.
Controller:
return View::make('log.index')
->with('logs',log::all());
Blade template
#foreach($logs as $log)
<tr>
<td>{{$log->id}}</td>
<td>{{$log->users()->name}}</td>
<td>{{$log->tasks()->name}}</td>
<tr>
#endforeach
but unable to fetch users Name and Tasks name from the respective table. any help is appreciated.
A better way is to define inverse hasMany relation in your Model, as documented here
So in your logs model, probably you need to define:
class Log extends Eloquent {
protected $table = "logs";
public function user(){
return $this->belongsTo('User');
}
public function task(){
return $this->belongsTo('Task');
}
}
Then in your view you can either use :
$log->user()->first()->name
or even better, by using Dynamic Properties:
$log->user->name
$log->users() and $log->tasks() returns a query object. Below, each call returns the result which is the same as calling $log->users()->get() and $log->tasks()->get(). Because the relationships are many to many, you'll need to iterate over $log->users and $log->tasks to retrieve each record.
#foreach($logs as $log)
<tr>
<td>{{$log->id}}</td>
<td>
#foreach($log->users as $user)
{{$user->name}},
#endforeach
</td>
<td>
#foreach($log->tasks as $task)
{{$task->name}},
#endforeach
</td>
<tr>
#endforeach
If you want a specific user/task attached to a log you'll have to build a query.
#foreach($logs as $log)
<tr>
<td>{{$log->id}}</td>
<td>{{$log->users()->where('id', '=', $userID)->first()->name}} </td>
<td>{{$log->tasks()->where('id', '=', $taskID)->first()->name}} </td>
<tr>
#endforeach
