I am trying to check in my model method if there was affected any rows if so return true else return false, but I don't know how to get it?:
class User_model extends CI_Model {
function __construct()
{
parent::__construct();
}
function save_new_user ($name, $email, $password)
{
$data = array(
'name' => $name,
'email' => $email,
'password' => $password,
'time' => time()
);
$this->db->insert('users', $data);
// if (affected rows > 0) return true else return false
if ([AFFECTED_ROWS] > 0) return true;
else return false;
}
}
The method you are looking for is $this->db->affected_rows().
So your return statement could look like this:
return $this->db->affected_rows() > 0;

I'm facing a weird problem that only accurs when I use pagination with livewire components,
this is the error:
BadMethodCallException
Method Illuminate\Support\Collection::items does not exist.
I know what this errors means, the problem is why it only accurs when I change page in pagination:
this is my Component:
<?php
namespace App\Http\Livewire\Admin;
use Livewire\Component;
use Livewire\WithPagination;
use Livewire\WithFileUploads;
use App\Models\Product;
use App\Models\Category;

$this->products = collect($this->products->items());
return view('livewire.admin.products', [

The idea is that I want to achieve search, store, update, delete, filter operations in same compoenent like in laravel controller, I found solutions online, but only 50% of what I need to achieve.
I have been wasting a lot of time trying to figure this out.
If any one would help me, I will be much appreciated.
At first glance without seeing the view, you are getting the $produts via the mount() method, this will only run ONCE when the livewire component is first rendered. From the docs:
mount() is only ever called when the component is first mounted and will not be called again even when the component is refreshed or rerendered.
I am using Laravel-8 and Maatwebsite-3.1 package to import Excel into the DB using Laravel API as the endpoint.
Trait:
trait ApiResponse {
public
function coreResponse($message, $data = null, $statusCode, $isSuccess = true) {
if (!$message) return response() - > json(['message' => 'Message is required'], 500);
// Send the response
if ($isSuccess) {
return response() - > json([
'message' => $message,
'error' => false,
'code' => $statusCode,
'results' => $data
], $statusCode);
} else {
return response() - > json([
'message' => $message,
'error' => true,
'code' => $statusCode,
], $statusCode);
}
}
public
function success($message, $data, $statusCode = 200) {
return $this - > coreResponse($message, $data, $statusCode);
}
public
function error($message, $statusCode = 500) {
return $this - > coreResponse($message, null, $statusCode, false);
}
}
Import:
class EmployeeImport extends DefaultValueBinder implements OnEachRow, WithStartRow, SkipsOnError, WithValidation, SkipsOnFailure
{
use Importable, SkipsErrors, SkipsFailures;
public function onRow(Row $row)
{
$rowIndex = $row->getIndex();
if($rowIndex >= 1000)
return; // Not more than 1000 rows at a time
$row = $row->toArray();
$employee = Employee::create([
'first_name' => $row[0],
'other_name' => $row[1] ?? '',
'last_name' => $row[2],
'email' => preg_replace('/\s+/', '', strtolower($row[3])),
'created_at' => date("Y-m-d H:i:s"),
'created_by' => Auth::user()->id,
]);
public function startRow(): int
{
return 2;
}
}
Controller:
public function importEmployee(Request $request)
{
try {
$validator = Validator::make($request->all(), [
'document' => 'file|mimes:xls,xlsx|max:5000',
]);
if ($request->hasFile('document'))
{
if($validator->passes()) {
$import = new EmployeeImport;
$file = $request->file('document');
$file->move(public_path('storage/file_imports/employee_imports'), $file->getClientOriginalName());
Excel::import($import, public_path('storage/file_imports/employee_imports/' . $file->getClientOriginalName() ));
foreach ($import->failures() as $failure) {
$importerror = new ImportError();
$importerror->data_row = $failure->row(); // row that went wrong
$importerror->data_attribute = $failure->attribute(); // either heading key (if using heading row concern) or column index
$importerror->data_errors = $failure->errors()[0]; // Actual error messages from Laravel validator
$importerror->data_values = json_encode($failure->values());
$importerror->created_by = Auth::user()->id;
$importerror->created_at = date("Y-m-d H:i:s");
$importerror->save();
}
return $this->success('Employees Successfully Imported.', [
'file' => $file
]);
}else{
return $this->error($validator->errors(), 422);
}
}
} catch(\Throwable $e) {
Log::error($e);
return $this->error($e->getMessage(), $e->getCode());
}
}
I made it to SkipOnError and SkipOnFailure.
If there's error, it saves the error into the DB. This is working.
However, there is issue, if some rows fail it still display success (Employees Successfully Imported) based on this:
return $this->success('Employees Successfully Imported.
When there is partial upload, or all the rows or some of the rows have issues, I want to display this to the user. So that it will be interactive.
How do I achieve this?
Thanks
I have a problem with insert_id. I'm using CodeIgniter. I have a method in which I insert some values and in it I return
$insert_id=$this->db->insert_id();
return $insert_id;`
I want to use this value in another method in the same model. I tried that: $insert_id=$this->add_teacher_subject(); but in this way first method runs again and I doesn't receive last_insert_id , but this value +1. Please, tell me how could I solve this problem?
My model is:
public function add_teacher_subject() {
$date = new DateTime("now");
$data=array(
'teacher_id'=>$this->input->post('teacher'),
'user_id'=>$this->session->userdata['user_id'],
'created_at'=>$date->format('Y-m-d H:i:s')
);
$this->db->insert('student_surveys',$data);
$insert_id=$this->db->insert_id();
return $insert_id;
}
public function survey_fill()
{
$insert_id=$this->add_teacher_subject();
if ($this->input->post('answer')) {
$answers= $this->input->post('answer');
if (null !==($this->input->post('submit'))) {
$date = new DateTime("now");
foreach($answers as $question_id=>$answer)
{
$data = array(
'user_id'=>$this->session->userdata['user_id'],
'question_id'=>$question_id,
'answer'=>$answer,
'student_survey_id' => $insert_id
);
$this->db->insert('survey_answers', $data);
}
}
You can use SESSION[] for keeping last insert id:
public function add_teacher_subject() {
$date = new DateTime("now");
$data = array(
'teacher_id' => $this->input->post('teacher'),
'user_id' => $this->session->userdata['user_id'],
'created_at' => $date->format('Y-m-d H:i:s')
);
$this->db->insert('student_surveys', $data);
$insert_id = $this->db->insert_id();
$newdata = array('insert_id' => $insert_id);
$this->session->set_userdata($newdata);
return $insert_id;
}
public function survey_fill() {
$insert_id = $this->session->userdata('insert_id');
if ($this->input->post('answer')) {
$answers = $this->input->post('answer');
if (null !== ($this->input->post('submit'))) {
$date = new DateTime("now");
foreach ($answers as $question_id => $answer) {
$data = array(
'user_id' => $this->session->userdata['user_id'],
'question_id' => $question_id,
'answer' => $answer,
'student_survey_id' => $insert_id
);
$this->db->insert('survey_answers', $data);
}
}
}
}
I'm learning both Laravel and UnitTesting at the moment, so this may be a stupid question.
I'm getting stuck on how to best test the controller function below:
UserController:
public function store()
{
$input = Input::all();
$user = new User($input);
if( ! $user->save()){
return Redirect::back()->withInput()->withErrors($user->getErrors());
}
return Redirect::to('/user');
}
here's the test as I have it so far:
/**
* #dataProvider providerTestUserStoreAddsUsersCorrectly
*/
public function testUserStoreAddsUsersCorrectly($first_name, $last_name, $email, $password)
{
$response = $this->call('POST', 'user', array('first_name'=>$first_name, 'last_name'=>$last_name, 'email'=>$email, 'password'=>$password));
}
public function providerTestUserStoreAddsUsersCorrectly(){
return array(
array("FirstName", "LastName", "Email#add.com", "pass1234")
);
}
This is actually working and adding the user to the db correctly, but I'm not sure how to test the output / what assertions to use as the response should be to add the user to the db and to redirect to the /user page.
How do I finish this test?
If you need to check success status then you can simply send status code from your controller
and check status in test
public function store()
{
$input = Input::all();
$user = new User($input);
if( !$user->save() ){
return array("status"=>'failed');
}
return array("status"=>'success');
}
public function testUserStoreAddsUsersCorrectly($first_name, $last_name, $email, $password)
{
$requested_arr = [
'first_name' => $first_name,
'last_name' => $last_name,
'email' => $email,
'password' => $password
];
$response = $this->call('POST', 'user', $requested_arr);
$data = json_decode($response ->getContent(), true);
if ($data['status']) {
$this->assertTrue(true);
} else {
$this->assertTrue(false);
}
}
I am having trouble, getting the logged in user ID from the database...
This is my controller code :
function validation(){
$this->load->model('users_model');
$query = $this->users_model->validate();
if ($query){
$this->users_model->get_userID($this->input->post('email'));
$data = array(
'email' => $this->input->post('email'),
'is_logged_in' => true,
'user_id' => $user_id
);
$this->session->set_userdata($data);
redirect('home');
}
else {
$this->index();
}
}
This is my model function where I return the user id from the database:
function get_userID($email){
$this->db->where('email',$email);
$query = $this->db->get('users');
foreach ($query->result() as $row)
{
$user_id = $row->id;
}
return $user_id;
}
Everything works perfect, except that $user_id returns empty... What am I doing wrong?
Try:
$user_id= $this->users_model->get_userID($this->input->post('email'));
try modifying the model function to this -
function get_userID($email){
$this->db->where('email',$email);
$query = $this->db->get('users')->row_array(); // retrieves only first-row.
return $query['id'];
}
In controller the function needs just a bit of modification as follows -
function validation(){
$this->load->model('users_model');
$query = $this->users_model->validate();
if($query){
//$user_id was not assigned before :)
$user_id = $this->users_model->get_userID($this->input->post('email'));
$data = array(
'email' => $this->input->post('email'),
'is_logged_in' => true,
'user_id' => $user_id
);
$this->session->set_userdata($data);
redirect('home');
}
else {
$this->index();
}
}
hope it helps,
