How can I update multiple rows
I'm getting below array
[
"3",
"4",
"5"
]
My Controller
$answers= $request->get('option'); //answers array
foreach ($answers as $answer)
{
Answer::where('question_id', 1)->update(
['customer_id' => 1,
'answer' => $answer]);
}
You can use update() method:
Answer::where('question_id', 2)->update(['customer_id' => 1, 'answer' => 2]);
The update method expects an array of column and value pairs representing the columns that should be updated
Don't forget to add customer_id, answer to the $fillable array:
protected $fillable = ['customer_id', 'answer'];
If you are using query builder then use bellow query
DB::table('answers')
->where('question_id', 2)
->update(array('customer_id' => 1, 'answer' => 2]);
and if you are using Eloquent ORM then use bellow query
App\Answers::where('question_id', 2)->update(['customer_id' => 1,'answer'=>2]);
You can update with simple following query.
DB::table('answers')->where('id',2)->update(['customer_id' => 1, 'answer' => 2]);
It's better to use Eloquent Model like,
Answer::where('id',2)->update(['customer_id' => 1, 'answer' => 2]);
If you have not added these column in $fillable property of model then, you can update with after find like,
$answer = Answer::find(2);
$answer->customer_id = 1;
$answer->answer = 2;
$answer->save();
Hope you understand.

This is my data table image
my blade file
#table([
'id' => 'Persons.index',
'xhr' => route('api.manage-dup-api'),
'ns' => 'PersonsIndex',
'columns' => $columns ?? [],
'filters' => $filterTable ?? [],
'params' => [
'filters_live' => false,
'selectable' => true,
'toolbar_style' => 'fixed'
]
])
this is a query which passes data to a data table [API]
$q->with('user')
->with('user.roles')
->select(
'persons.*',
'birth->date as birthdate'
)->`enter code here`whereIn('id', $id)->orWhereIn('old_id_CONINET', $coninet_ids);
return $this->outputList($q, $request);
as shown in the picture I want to remove ["] from the CONINET_ID table
you are storing an array of strings in the DB.
you can convert the array values to int:
array_map('intval', $array);
you can also create an accessor on your eloquent model
public function getOldIdConinetAttribute($value)
{
return array_map('intval', $value);
}
It would better if you give some detailed info. As of now details mentioned above can not explain your code. As of my understanding, I suggest you to check Yajra datatable plugin which will help you solving your issue.
or you can cast coninet_id to array by adding below code in your model.
protected $casts = [
'coninet_id' => 'array'
];
I use laravel 5.6
I have a json file containing 500 thousand records. I want to create a logic to check whether the id of each record already exists or not in the database. If it doesn't already exist, then there will be a data insert process. If it already exists, there will be a data update process
I have made logic. I just want to make sure whether my logic is effective or not
My logic code like this :
$path = storage_path('data.json');
$json = json_decode(file_get_contents($path), true);
foreach ($json['value'] as $value) {
$data = \DB::table('details')->where('id', '=', $value['Code'])->get();
if ($data->isEmpty()) {
\DB::table('details')->insert(
[
'id' => $value['Code'],
'number' => $value['Number'],
...
]
);
}
else {
\DB::table('details')
->where('id', '=', $value['Code'])
->update([
'id' => $value['Code'],
'number' => $value['Number'],
...
]);
}
}
The code is working. But the process seems really long
Do you have another solution that is better?
updateOrCreate
You may also come across situations where you want to update an existing model or create a new model if none exists. Laravel provides an updateOrCreate method to do this in one step. Like the firstOrCreate method, updateOrCreate persists the model, so there's no need to call save():
// If there's a flight from Oakland to San Diego, set the price to $99.
// If no matching model exists, create one.
$flight = App\Flight::updateOrCreate(
['departure' => 'Oakland', 'destination' => 'San Diego'],
['price' => 99]
);
in your case your code should be like this (create Details model first) :
$path = storage_path('data.json');
$json = json_decode(file_get_contents($path), true);
foreach ($json['value'] as $value) {
Details::updateOrCreate(
[ 'id' => $value['Code'] ],
[ 'number' => $value['Number'], ... ]
);
}
i think that's the best way to do it. Eloquent return's a collection so you cant just validate that your string is null.
please help I dont know how to get relation table when using sqldataprovider. Anyone understand how to use relation model?
$model = new Finalresult();
$searchModel = new FinalresultSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
$dataProvider = new SqlDataProvider([
'sql' => 'SELECT finalresult.bib,
finalresult.series_id,
finalresult.category_id,
GROUP_CONCAT(DISTINCT finalresult.point ORDER BY series.serie_seri_no DESC) AS seriPoint
FROM finalresult, series GROUP BY finalresult.bib',
'key' => 'bib',
]);
I'm trying to get relation table:
'attribute'=>'category_id',
'width'=>'300px',
'value'=>function ($model, $key, $index, $widget) {
return $model->category->category_name;
},
then getting trying to non-object
You can't use relations with SqlDataProvider, because each single result will be presented as array, for example:
[
'id' => 1,
'name' => 'Some name',
'category_id' => 1,
],
For example, you can access category_id as `$model['category_id'].
SqlDataProvider is for very very complex queries, your query can easily be written as ActiveQuery and you can use ActiveDataProvider and get all advantages of that (relations, etc.).
You can find category by id, but it will be lazily loaded that means amount of queries is multiplied by number of rows.
With ActiveDataProvider and relations you can use eager loading and reduce amount of queries. Read more in official docs.
Grid Columns example in documentation
try to change "value" to
'value'=> function($data) {
return $data['category']['category_name'];
}
My model has
Conversations - hasMany - Messages
Conversations - hasMany - ConversationsRecipients
ConversationsRecipients - belongTo - Users or Applicants (depending on the flag set by field recipient_type. If recipient_type is A then it means Applicants)
So when I try to retrieve conversations for a particular Applicant, I use the following code
$conversationsTable = TableRegistry::get('Conversations');
$conversations = $conversationsTable->find()
->join([
'ConversationsRecipients' => [
'table' => 'conversations_recipients',
'type' => 'inner',
'conditions' => ['recipient_id' => $id, 'recipient_type' => 'A']
]
])
->contain([
'Messages.Users' => function ($q) {
return $q
->select(['Users.username'])
->contain(['UsersProfiles']);
},
'Messages.Applicants' => function($q) {
return $q
->select(['Applicants.firstname', 'Applicants.lastname']);
}
])
->all();
return $conversations;
This works fine - except for one part - but it doesn't retrieve the deeply contained model - UsersProfiles. Am I missing something?
Try this:
return $q
->select(['Users.username'])
->autoFields(true)
->contain(['UsersProfiles']);
When you include a select in your query, that's all that Cake will include, unless you include the autoFields call.
I am generating related records search query for Gridview use
I get this error :
SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'dbowner' in where clause is ambiguous
The SQL being executed was: SELECT COUNT(*) FROM tbl_iolcalculation LEFT JOIN tbl_iolcalculation patient ON tbl_iolcalculation.patient_id = patient.id WHERE (dbowner=1) AND (dbowner=1)
I have two related models 1) iolcalculation and patient - each iolcalculation has one patient (iolcalculation.patient_id -> patient.id)
The relevant code in my model IolCalculationSearch is :
public function search($params)
{
$query = IolCalculation::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$dataProvider->sort->attributes['patient.lastname'] = [
'asc' => ['patient.lastname' => SORT_ASC],
'desc' => ['patient.lastname' => SORT_DESC],
];
$query->joinWith(['patient'=> function($query) { $query->from(['patient'=>'tbl_iolcalculation']); } ]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$query->andFilterWhere([
'id' => $this->id,
'patient_id' => $this->patient_id,
'preop_id' => $this->preop_id,
'calculation_date' => $this->calculation_date,
'iol_calculated' => $this->iol_calculated,
The reason this error is generated is that each model has an override to the default Where clause as follows, the reason being that multiple users data needs to be segregated from other users, by the field dbowner:
public static function defaultWhere($query) {
parent::init();
$session = new Session();
$session->open();
$query->andWhere(['t.dbowner' => $session['dbowner']]);
}
this is defined in a base model extending ActiveRecord, and then all working models extend this base model
How Can I resolve this ambiguous reference in the MySQL code?
Thanks in advance
$query->andFilterWhere([
// previous filters
self::tableName() . '.structure_id' => $this->structure_id,
// next filters
]);
I think, that you are searching for table aliases.
(https://github.com/yiisoft/yii2/issues/2377)
Like this, of course you have to change the rest of your code:
$query->joinWith(['patient'=> function($query) { $query->from(['patient p2'=>'tbl_iolcalculation']); } ]);
The only way I can get this to work is to override the default scope find I had set up for most models, so that it includes the actual table name as follows - in my model definition:
public static function find() {
$session = new Session();
$session->open();
return parent::find()->where(['tbl_iolcalculation.dbowner'=> $session['dbowner']]);
}
There may be a more elegant way using aliases, so any advice would be appreciated - would be nice to add aliases to where clauses, and I saw that they are working on this....
