$data = array(
['name' => 'John Doe', 'email' => 'john#email.com'],
['name' => 'Robert Roe', 'email' => 'robert#email.com']
);
$users = new Collection($data);
return Datatables::of($users)->make();
I'm using the yajra/laravel-datatables plugin, it shows me that Collection functions are available on v5.x and later, but after i installed v5.11.10, and tried the above code, it gives me a Class 'Collection' not found error.
Should be a namespace issue. Make sure:
use Illuminate\Support\Collection;
is included at the top of your controller.

I am using Laravel 7.
I have Category model. I sent categories as API with laravel resources. But now I want to add "all" value to categories.
Controller:
'categories' => CategoryResource::collection(Category::all()->push([
'id' => 0,
'name' => "All",
'subcategories' => []
]))
Resource:
public function toArray($request)
{
return [
'id' => $this->id,
'name' => $this->name,
'subcategories' => SubcategryResource::collection($this->subcategories)
];
}
Also, I wanted to add this custom value to the beginning of the collection.
But I am getting this error:
Trying to get property 'id' of non-object
Please, help me. How can I solve my problem?
Try replacing $this->id with $this['id']
If that works your query is returning an array not an object.
The problem here is that you're trying to add an item to the collection which is not a category model. $this in the resource reverts to the given model. However, you pass in an array so there is no model.
So try this instead
$allCategory = new Category(['id' => 0, 'name' => 'All']);
'categories' => CategoryResource::collection(Category::all()->prepend($allCategory));
I got these from: https://laracasts.com/discuss/channels/eloquent/add-a-custom-value-to-eloquent-collection
General Information
I'm using this package
GeocoderLaravel Version: 4.0.0
Laravel Version: 5.6
PHP Version: 7.2.4
Operating System and Version: Windows 10
Issue Description
FatalThrowableError (E_ERROR)
Call to a member function getStreetNumber() on null
This happens maybe 1/10 times. Even when I use the same coordinates. Rest of the time it works fine. If I get the error and just refresh/resubmit the form it will work. So not sure how to solve this issue.
My one guess is that it is exicuting Location::create() before an object is returned to $geo, but I don't know what could be done to fix that. Any help would be much appreciated
Here is my controller:
$lat = request('lat');
$lng = request('lng');
$geo = Geocoder::reverse($lat, $lng)->get()->first();
$location = Location::create([
'lat' => $lat,
'lng' => $lng,
'user_id' => Auth::user()->id,
'streetNumber' => $geo->getStreetNumber(),
'streetName' => $geo->getStreetName(),
'cityDistrict' => $geo->getSubLocality(),
'city' => $geo->getLocality(),
'zipcode' => $geo->getPostalCode(),
'country' => $geo->getCountry(),
'timezone' => $geo->getTimezone()
]);
So I'm planning to start using resources for my "API" (vue endpoint). So I started to search for some tutorials about the subject, and found a youtuber that describes the process. And I started making my own API resource. The youtuber shows briefly how to use the relations, but the thing is that I receive Property [description] does not exist on this collection instance. when trying to use the relation in the resource.
The current setup is:
$stack = Stack::select(['id', 'name', 'subject_id', 'description', 'image'])->where('id', '=', $requestId)->first();
$questions = $stack->load('question.choiceInRandomOrder');
return $questions;
And with resource it would be something like (notice choiceInRandomOrde, I would need that relation also):
return [
'subject' => $this->subject->name,
'name' => $this->name,
'slug' => $this->slug,
'description' => $this->description,
'image' => $this->image,
'questions' => [
'description' => $this->question->description,
'is_info' => $this->question->is_info,
'source' => $this->question->source,
'image' => $this->question->image,
]
];
}
And for testing, I have setup the following in my routes web.php
use App\Stack;
use App\Http\Resources\StackResource;
Route::get('/json', function(){
$stack = Stack::find(2);
return new StackResource($stack);
});
You try to access the name of subject in 'subject' => $this->subject->name, but you do not load the relation.
i don't know if i'm right but i thnk it has to be with the fact that ure not doing an Eloquent call but a Query Builder call (when doing $stack = Stack::select ... ). Why select just some fields in the call if you can choose the parameters to show directly in the model class? (see this).
Try to doing an Eloquent call instead (something like Stack::find(1)) and test it. It should work.
I'm using Query builder, I successfully update na first column but on the second query the change doesnt happen, I already checked the view part the name of input and its correct. here is my code.
DB::table('area')
->where('id', $request->get('area_id'))
->update(['island_group_id' => $request->get('island_group_id')],
['region_id' => $request->get('region_id')]);
return 'test';
$updateDetails = [
'island_group_id' => $request->get('island_group_id'),
'region_id' => $request->get('region_id')
];
DB::table('area')
->where('id', $request->get('area_id'))
->update($updateDetails);
DB::table('area')
->where('id', $request->get('area_id'))
->update([
'island_group_id' => $request->get('island_group_id'),
'region_id' => $request->get('region_id')
]);
return 'test';
I think it will be helpful to you.
$area_id = $request->get('area_id');
$island_group_id = $request->get('island_group_id');
$region_id = $request->get('region_id');
$update_details = array(
'island_group_id' => $island_group_id
'region_id' => $region_id
);
DB::table('area')
->where('id', $area_id)
->update($update_details);
Because you use every time new array for update field. Please use one array for update multiple field like:
DB::table('area')
->where('id', $request->get('area_id'))
->update(array(
'island_group_id'=>$request->get('island_group_id'),
'region_id'=>$request->get('region_id')
));
I am currently working on a custom module add-on and I wanted to be able to use sorting and filtering on the a table in my control panel admin. I am using the EE table class and form helper. I'm trying to follow the documentation here for setting it up, but when I call try to call the '_datasource' method in my class I get this error
Fatal error: Call to undefined method Content_publish::_datasource() in /home/public_html/system/expressionengine/libraries/EE_Table.php on line 162
I have a feeling it's a scoping issue, but in the table class '$this->EE->table->datasource()' method you are supposed to just pass a string value with the name of your datasource function which is what I'm doing.
I don't seem to be the only one with this issue. There are more details and code examples on this EE Discussion forum thread
The documentation is not really clear. I also tried looking at EE's own comments module to see if i could figure it out, but no luck. Anyone have experience with this?
Here is the method I'm calling:
$data = $this->EE->table->datasource('_datasource');
And this is my function in my class:
function _datasource()
{
// ....
// $query comes from DB result set code above.
// I have omitted it here for brevity
$datarows = array();
foreach ($query->result_array() as $key => $row)
{
$datarows[] = array(
'entry_id' => $row['entry_id'],
'date' => date('Y-m-d',$row['entry_date']),
'author' => $row['screen_name'],
'payment' => $payment_amount,
'status' => $status,
'title' => $edit_href.$row['title']."</a>"
);
}
return $datarows;
}
Your datasource callback function must be on your Module_mcp class (looking at your forum thread you are trying to use it on a plugin which would explain the error).
If you want to put the datasource method on a different class, then just add this line right before you call datasource() to trick the table library into using the correct class:
// ensure table callbacks use this class rather than our MCP file
$this->EE->_mcp_reference =& $this;
$data = $this->EE->table->datasource('_datasource');
The table and form_validation libraries are the only two which use the special _mcp_reference variable, so I can't see any side effects to changing it, and have successfully done this in at least two modules.
On a side note, if you want a good example of how to use the built in tablesorter, take a look at system/expressionengine/controllers/cp/members.php. The documentation is pretty bad, but the source code always tells the truth :)
I've been having issues too and have a mixed solution of generate() and datasource working. Here it is here:
In my mcp file:
public function index()
{
$this->EE->cp->set_variable('cp_page_title', lang('my_module_name'));
$data = $this->EE->table->datasource('_datasource');
return $this->EE->load->view('index', $data, TRUE);
}
public function _datasource()
{
$headers = array(
'name' => array('header' => 'Name'),
'color' => array('header' => 'Color'),
'size' => array('header' => 'Size')
);
$rows = array(
array('name' => 'Fred', 'color' => 'Blue', 'size' => 'Small'),
array('name' => 'Mary', 'color' => 'Red', 'size' => 'Large'),
array('name' => 'John', 'color' => 'Green', 'size' => 'Medium'),
);
return array(
'rows' => $rows,
'headers' => $headers
);
}
In my index view file:
$this->table->set_columns($headers);
$this->table->set_data($rows);
echo $this->table->generate();
Seems to be working at the moment and I've not tried pagination yet, but sorting works.
