I am new to Laravel 5 and MVC. I can not figure out why is my INSERT query not running but JUST directing me to search page. below is my code.
edit: the database connection is proper and I can view data on page via same database
public function insert()
{
DB::table('patients')->insert(
array('name' => 'fakhir', 'email' => 'hello#email.com')
);
return view('patients/search');
}
Try '->where', let me know what you get.
public function insert()
{
DB::table('patients')->where('#')->insert(
array('name' => 'fakhir', 'email' => 'hello#email.com')
);
return view('patients/search');
}
have you tried to adding with eloquent ? I think firstly, You should try to adding with eloquent.
You test it in this way
Patients::create(['name'=>'fakhir','email'=>'hello#email.com']);

I have created method in the Yii2 model Users to get all the replies for the current user
public function getAllRepliesForUsers() { return $this->hasMany(Replies::class, ['user_id' => 'id'])->viaTable('replies_links', ['replies_id' => 'id'])->where(['entity'=>'user']); }
My replies table
My users table
and the final table that links these two tables
Is my method is correct?
Here's the relationship of Users to the Replies. You can use the Model generator of Gii module so you won't get confused by manually typing them.
public function getReplies()
{
return $this->hasMany(Replies::className(), ['id' => 'reply_id'])->viaTable('rply_links', ['user_id' => 'id']);
}
(May I know what do you intend to do with the condition ->where(['entity'=>'user'])?).
I'm new to Laravel. I need to retrieve specific data from the database using the JSON decode. I am currently using $casts to my model to handle the JSON encode and decode.
This is my insert query with json encode:
$request->validate([
'subject' => 'required|max:255',
'concern' => 'required'
]);
$issue = new Issue;
$issue->subject = $request->subject;
$issue->url = $request->url;
$issue->details = $request->concern;
$issue->created_by = $request->userid;
$issue->user_data = $request->user_data; //field that use json encode
$issue->status = 2; // 1 means draft
$issue->email = $request->email;
$issue->data = '';
$issue->save();
The user_data contains {"id":37,"first_name":"Brian","middle_name":"","last_name":"Belen","email":"arcega52#gmail.com","username":"BLB-Student1","avatar":"avatars\/20170623133042-49.png"}
This is my output:
{{$issue->user_data}}
What I need to retrieve is only the first_name, middle_name, and last_name. How am I supposed to achieve that? Thank you in ADVANCE!!!!!
As per the above code shown by you it will only insert data into the database.For retrieving data you can make use of Query Builder as i have written below and also you can check the docs
$users = DB::table('name of table')->select('first_name', 'middle_name', 'last_name')->get();
I will recommend using Resources. It really very helpful laravel feature. Check it out. It is a reusable class. You call anywhere and anytime.
php artisan make:resource UserResource
Go to your the newly created class App/Http/Resources/UserResource.php and drfine the column you want to have in your response.
public function toArray($request) {
return [
"first_name" => $this->first_name,
"middle_name" => $this->middle_name,
"last_name" => $this->last_name
]
}
Now is your controller you can use the UserResource like folow:
public function index()
{
return UserResource::collection(User::all());
}
Or after inserting data you can return the newly added data(f_name, l_name...)
$user = new User;
$user->first_name= $request->first_name;
$user->middle_name= $request->middle_name;
$user->last_name= $request->last_name;
$user->save();
$user_data= new UserResource($user);
return $user_data;
Any one know how to send error messages to database in laravel which generate from app/exceptions/handler.php ?
I need to send what error massages generated in report() method to database.
If you are interested doing this manually, you can do something as following.
Step 1 -
Create a model to store errors that has a DB structure as following.
class Error extends Model
{
protected $fillable = ['user_id' , 'code' , 'file' , 'line' , 'message' , 'trace' ];
}
Step 2
Locate the App/Exceptions/Handler.php file, include Auth, and the Error model you created. and replace the report function with the following code.
public function report(Exception $exception) {
// Checks if a user has logged in to the system, so the error will be recorded with the user id
$userId = 0;
if (Auth::user()) {
$userId = Auth::user()->id;
}
$data = array(
'user_id' => $userId,
'code' => $exception->getCode(),
'file' => $exception->getFile(),
'line' => $exception->getLine(),
'message' => $exception->getMessage(),
'trace' => $exception->getTraceAsString(),
);
Error::create($data);
parent::report($exception);
}
(I am demonstrating this using laravel 5.6)
Because Laravel uses Monolog for handling logging it seems that writing Monolog Handler would be the cleanest way.
I was able to find something that exists already, please have a look at monolog-mysql package. I did not use it, so I don't know whether it works and if it works well, but it's definitely good starting point.
I am trying to create efficient JSON Response controllers for AJAX. So far, instead of passing whole entity to JsonResponse I am creating arrays with necessary data inside where I can easily manage output data leaving less work for JavaScript. My action looks something like this:
public function getOffersAction(Request $request)
{
if (!$request->isXmlHttpRequest()) {
return new JsonResponse(array('message' => 'You can access this only using Ajax!'), 400);
}
/** #var OfferRepository $offerRepository */
$offerRepository = $this->getDoctrine()->getRepository('IndexBundle:Offer');
$offers = $offerRepository->findBy(array('state' => 'available'));
$offersArray = array();
/** #var Offer $offer */
foreach ($offers as $offer) {
$areasArray = array();
foreach ($offer->getAreas() as $area) {
$areasArray[] = array(
'name' => $area->getName()
);
}
$offersArray[] = array(
'id' => $offer->getId(),
'code' => $offer->getCode(),
'title' => $offer->getTitle(),
'city' => $offer->getCity(),
'country' => $offer->getCountry()->getName(),
'latitude' => $offer->getLatitude(),
'longitude' => $offer->getLongitude(),
'areas' => $areasArray
);
}
return new JsonResponse($offersArray, 200);
}
It is all good, ajax is working fast.
At this point I started googling searching if this is a right approach to it. I found out about JMSSerializerBundle which serializes entities. I tried using it, but I am facing problems serializing relationships and how to access related entities data using JS. It is so complicated leaving so many proccessing to do for JS that I start doubting that it is a good approach.
What do you think? What is your experience with it? Which approach is better and why?
I prefer the symfony normalizer/serializer approach.
http://symfony.com/doc/current/components/serializer.html
As described, you can overide serializer to serialize your object in the same custom way for your whole application
I am not very good with DB queries. And with Yii it's more complicated, since I am not very used to it.
I need to optimize a simple query
$userCalendar = UserCalendar::model()->findByAttributes(array('user_id'=>$user->id));
$unplannedEvents = CalendarEvent::model()->findAllByAttributes(array('calendar_id'=> $userCalendar->calendar_id,'planned'=>0));
CalendarEvent table, i.e the second table from which I need records does not have an user_id but a calendar_id from which I could get user_id from UserCalendar, i.e. the first table hence I created a UserCalendar object which is not a very good way as far as I understand.
Q1. What could I do to make it into one.
Q2. Yii does this all internally but I want to know what query it built to try it seperately in MySQL(phpMyAdmin), is there a way to do that?
Thanks.
Q1: You need to have the relation between UserCalendar and CalendarEvent defined in both of your active record models (in the method "relations").
Based on your comments, it seems like you have the Calendar model that has CalendarEvent models and UserCalendar models.
Lets assume your relations in Calendar are:
relations() {
return array(
'userCalendar' => array(self::HAS_MANY, 'UserCalendar', 'calendar_id'),
'calendarEvent' => array(self::HAS_MANY, 'CalendarEvent', 'calendar_id'),
}
In CalendarEvent:
relations() {
return array( 'calendar' => array(self::BELONGS_TO, 'Calendar', 'calendar_id'), );
}
And in UserCalendar:
relations() {
return array( 'calendar' => array(self::BELONGS_TO, 'Calendar', 'calendar_id'), );
}
So to make the link between UserCalendar and CalendarEvent you'll need to use Calendar
$criteria = new CDbCriteria;
$criteria->with = array(
"calendarEvent"=>array('condition'=>'planned = 0'),
"userCalendar"=>array('condition'=> 'user_id =' . $user->id),
);
$calendar = Calendar::model()->find($criteria);
and $calendar->calendarEvent will return an array of calendarEvent belonging to the user
Q2: you can enable web logging so all the db request (and others stuffs) will appear at the end of your page:
Logging in Yii (see CWebLogging)
In your application configuration put
'components'=>array(
......
'log'=>array(
'class'=>'CLogRouter',
'routes'=>array(
array(
'class'=>'CWebLogRoute',
),
),
),
),
