I want to do filtering from the data that I display, but there is a problem when I add where to my data.
the plan in the future I want to add if isset $request name, date and others. but was constrained at this one point.
Thank you for helping to answer in advance
$matchs =Matchs::where('type', 'sparring')->where('status','Pending')->whereNull('deleted_at')->get()->toArray();
$data=[];
foreach ($matchs as $key) {
$lawan = Matchs::where('id', $key['id'])->first()->ToArray();
$pertandingan = Sparring::where('match_id', $key['id'])->first()->ToArray();
$dua_arah = MatchTwoTeam::where('match_id', $key['id'])->first()->ToArray();
$tim = Team::where('id', $dua_arah['home_team'])->first()->ToArray();
$transfer['name']=$tim['name'];
$transfer['city']=$lawan['city'];
$transfer['field_cost']=$pertandingan['field_cost'];
$transfer['referee_cost']=$pertandingan['referee_cost'];
$transfer['logo_path']=$tim['logo_path'];
$transfer['nama_lapangan']=$lawan['nama_lapangan'];
$transfer['date']=$lawan['date'];
array_push($data,$transfer);
array_push($data,$pertandingan);
}
$data->where('name', 'LIKE', '%'.'football'.'%')->get()->toArray();
$data = array_search('football', array_column($data, 'name'));
$tittle="Sparring";
return view('mode.sparring',[
'tittle' => $tittle,
'data' => $data,
]);
You are trying to call where in an array which is not possible.
As you can see in the first line of your code you are calling where method in your model class. Like Matchs::where('type', 'sparring'), this is possible because Matchs is a Model class.
Now you can run where even if you are using array. You can convert that day in collection and then use array on that collection.
As below:
collect($data)->where('name', 'football')->toArray();
Here collect() will convert the $data array to collectio and then run the where() method in collectio then toArray() will change it back to array. But unfortunately there is no like operator possible in collection class. See the list of available method in Laravel collection here: https://laravel.com/docs/8.x/collections#available-methods
There is a way to do what you are trying to do. As far as I understand you want to filter the Matches where the Team name has footbal in it. You can do it like this:
Matchs::where('type', 'sparring')
->where('status','Pending')
->whereNull('deleted_at')
->whereHas('team', function($team) {
return $team->where('name', 'LIKE', '%'.'football'.'%')
})
->get()
->toArray();
So, here we can get the only those Mathes that has the Team that has the name contains football.
Few suggestion for you as seems you are new in Laravel:
Model name should be singular instead of plural, so the model class Matchs should be Match. Your name for team's model is Team is correct.
Avoid using toArray() because you won't need it. When you call get() it will return object of collection which more readable and powerful then array in most cases.
The code I suggested to use the like using whereHas will only work if you have propery defined your team relation in your Matchs class. So, defining your relationships in model is also important. If you do so, you don't even need the for loop and all those where in other model in that loop. You can do it in one query with all the relationships.
Using Laravel 5.3, I have a model with the following function
public function myData() {
return $this->hasMany(MyData::class);
}
and in my collection I have the following
$my_data = MyModel->myData()->get();
All good so far. If I return $my_data I get an eloquent collection with three items.
What I need now though is to create a duplicate of that collection but containing only three of the fields.
I have tried several different things, each of which return an error. The following is the closest I have got, but this returns an empty array - I assume because the fields are located one level deeper than the collection object.
$new_collection = $my_data->only(['field_1', 'field_2', 'field_3']);
What would be the correct way to create a new collection containing all three items, each with only the three selected fields?
Thanks for your help
You could use map:
$slimmed_down = $collection->map(function ($item, $key) {
return [
'field_1' => $item->field_1,
'field_2' => $item->field_2,
'field_3' => $item->field_3
];
});
This will return a new Collection with just the values you want. As far as I know there isn't any other method that does what you want, so iterating over every item and selecting the fields this way is one of the few solutions.
The advantage of using map instead of a standard foreach loop is that when you use map it returns a new instance of Collection.
Edit:
After some thoughts and research about this, the problem you'll have created is that the all the values in the Collection aren't instances of anything anymore. If you don't mind this effect, an even prettier and faster way would be to do this:
$slimmed_down = $collection->toArray()->only(['field_1', 'field_2', 'field_3']);
This basically has the same result.
Using Laravel 9, I just had the same issue :
$my_data->only(['field_1', 'field_2', 'field_3']);
returning an empty array.
I solved it with :
$my_data->map->only(['field_1', 'field_2', 'field_3']);
lets say I have 7 columns in table, and I want to select only two of them, something like this
SELECT `name`,`surname` FROM `table` WHERE `id` = '1';
In laravel eloquent model it may looks like this
Table::where('id', 1)->get();
but I guess this expression will select ALL columns where id equals 1, and I want only two columns(name, surname). how to select only two columns?
You can do it like this:
Table::select('name','surname')->where('id', 1)->get();
Table::where('id', 1)->get(['name','surname']);
You can also use find() like this:
ModelName::find($id, ['name', 'surname']);
The $id variable can be an array in case you need to retrieve multiple instances of the model.
By using all() method we can select particular columns from table like as shown below.
ModelName::all('column1', 'column2', 'column3');
Note: Laravel 5.4
You first need to create a Model, that represent that Table and then use the below Eloquent way to fetch the data of only 2 fields.
Model::where('id', 1)
->pluck('name', 'surname')
->all();
Also Model::all(['id'])->toArray() it will only fetch id as array.
Get value of one column:
Table_Name::find($id)->column_name;
you can use this method with where clause:
Table_Name::where('id',$id)->first()->column_name;
or use this method for bypass PhpStorm "Method where not found in App\Models":
Table_Name::query()->where('id','=',$id)->first()->column_name;
in query builder:
DB::table('table_names')->find($id)->column_name;
with where cluase:
DB::table('table_names')->where('id',$id)->first()->column_name;
or
DB::table('table_names')->where('id',$id)->first('column_name');
last method result is array
You can use get() as well as all()
ModelName::where('a', 1)->get(['column1','column2']);
From laravel 5.3 only using get() method you can get specific columns of your table:
YouModelName::get(['id', 'name']);
Or from laravel 5.4 you can also use all() method for getting the fields of your choice:
YourModelName::all('id', 'name');
with both of above method get() or all() you can also use where() but syntax is different for both:
Model::all()
YourModelName::all('id', 'name')->where('id',1);
Model::get()
YourModelName::where('id',1)->get(['id', 'name']);
To get the result of specific column from table,we have to specify the column name.
Use following code : -
$result = DB::Table('table_name')->select('column1','column2')->where('id',1)->get();
for example -
$result = DB::Table('Student')->select('subject','class')->where('id',1)->get();
use App\Table;
// ...
Table::where('id',1)->get('name','surname');
if no where
Table::all('name','surname');
If you want to get a single value from Database
Model::where('id', 1)->value('name');
Also you can use pluck.
Model::where('id',1)->pluck('column1', 'column2');
You can use Table::select ('name', 'surname')->where ('id', 1)->get ().
Keep in mind that when selecting for only certain fields, you will have to make another query if you end up accessing those other fields later in the request (that may be obvious, just wanted to include that caveat). Including the id field is usually a good idea so laravel knows how to write back any updates you do to the model instance.
You can get it like
`PostModel::where('post_status', 'publish')->get(['title', 'content', 'slug', 'image_url']`)
link
you can also used findOrFail() method here it's good to used
if the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these method not give a 500 error..
ModelName::findOrFail($id, ['firstName', 'lastName']);
While most common approach is to use Model::select,
it can cause rendering out all attributes defined with accessor methods within model classes. So if you define attribute in your model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* Get the user's first name.
*
* #param string $value
* #return string
*/
public function getFirstNameAttribute($value)
{
return ucfirst($value);
}
}
And then use:
TableName::select('username')->where('id', 1)->get();
It will output collection with both first_name and username, rather than only username.
Better use pluck(), solo or optionally in combination with select - if you want specific columns.
TableName::select('username')->where('id', 1)->pluck('username');
or
TableName::where('id', 1)->pluck('username'); //that would return collection consisting of only username values
Also, optionally, use ->toArray() to convert collection object into array.
If you want to get single row and from the that row single column, one line code to get the value of the specific column is to use find() method alongside specifying of the column that you want to retrieve it.
Here is sample code:
ModelName::find($id_of_the_record, ['column_name'])->toArray()['column_name'];
If you need to get one column calling pluck directly on a model is the most performant way to retrieve a single column from all models in Laravel.
Calling get or all before pluck will read all models into memory before plucking the value.
Users::pluck('email');
->get() much like ->all() (and ->first() etc..) can take the fields you want to bring back as parameters;
->get/all(['column1','column2'])
Would bring back the collection but only with column1 and column2
You can use the below query:
Table('table')->select('name','surname')->where('id',1)->get();
If you wanted to get the value of a single column like 'name', you could also use the following:
Table::where('id', 1)->first(['name'])->name;
For getting multiple columns (returns collection) :
Model::select('name','surname')->where('id', 1)->get();
If you want to get columns as array use the below code:
Model::select('name','surname')->where('id', 1)->get()->toArray();
If you want to get a single column try this:
Model::where('id', 1)->first(['column_name'])->column_name;
Is it possible to bind a form with a model that has relationships? For example I have a Order model that has a one to many with a Details model. That would save a lot of time with
#foreach($order->details as $detail)
{{ Form::text('product_name', Input::old('product_name') ? Input::old('product_name') : detail->product_name)
#endforeach
For a one-to-one relation it's possible to use something like this:
Form::text('detail[product_name]')
In this case $order->detail->product_name will be populated in the given text box if an instance of Order model is bound to the from using Form::model($order) with the related model Detail but it may not possible for one-to-many because simply there will be a collection and you need a loop.
To complete the answer of #WereWolf..
Make an array of product_name detail_names
Input class allow you to access nested array by dot notation, eg: orders.1.product_name
Don't forget the second argument of Input::old() or Input::get()
is the default value, so you can specify the DB value and avoid conditional test..
.
Form::text('detail_names['.$detail->id.']', Input::old('detail_names.'.$detail->id, $detail->product_name))
In your controller, something like that:
foreach(Input:get('detail_names') as $id => $product_name)
{
//...
}
Hope this will help you to save a bit of time.
The problem is I need to pull a collection from a collection. I have already set up the models and database so these relationships work:
A User can have many Negotiations
A Negotiation has one RiderNegotiation
However I can't perform this query:
$user->negotiations->riderNegotiation
I thought I could get around this in my view file if I just passed off $user->negotiation and then parse through the negotiations. I discovered I can't use isEmpty() this way however.
#if($negotiations->riderNegotiation->isEmpty()
Is there some kind of nifty trick in Laravel to do this kind of relationship querying? I feel like this is a common issue.
hasMany returns a Collection of elements and you can't call hasOne on a Collection.
You should be able to do:
$negociations = User::find(1)->negotiations;
#foreach($negociations as $negociation)
echo get_class($negociation->riderNegotiation); //riderNegotiation
#endforeach
$negotiations = User::find(Auth::user()->id)->negotiations;
$temp = array();
foreach($negotiations as $negotiation ) {
$temp = array_merge($temp,$negotiaton->riderNegotiation->toArray());
};
A little resource expensive but $temp should contain all rider negotiations for that user.
