To create a custom token password reset in Laravel 5.5 (Or Lumen)

Please use the below passwordResetToken() function to get the token for password reset for custom use.

namespace App\Traits;

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Mail\Message;
use Illuminate\Support\Facades\Password;

trait ResetPasswordTrait 
{
    ...
    ...
    ...
    ...

    /**
     * Get the token for password reset and update the token in the database table.
     *
     * @return string|null
     */
    public function passwordResetToken($user)
    {
        $this->broker = 'users';

        $broker = $this->getBroker();

        return Password::broker($broker)->createToken($user);
    }

    /**
     * Get the broker to be used during password reset.
     *
     * @return string|null
     */
    public function getBroker()
    {
        return property_exists($this, 'broker') ? $this->broker : null;
    }

}


// Reuse in the class
use App\Traits\ResetPasswordTrait;

class NewUserAccount 
{

    use ResetPasswordTrait;

    // Sample function to print the password reset token
    public function printPasswordResetToken(Request $request)
    {
        $user = User::find( $request->input('id') );
        $passwordResetToken = $this->passwordResetToken($user);
        print_r($passwordResetToken);
    }

}

Generate Ramdon String on Shell

# Bash function to generate the random alphanumeric string with provided length.
randomString() {
    DEFAULT_LENGTH=6

    # if the parameter is not null, apply new length
    if [ ! -z "$1" -a "$1" != " " ]; then
        LENGTH=$1
    else
        LENGTH=$DEFAULT_LENGTH
    fi
    echo $LENGTH;

    LC_ALL=C tr -dc 'a-zA-Z0-9' < /dev/urandom | fold -w $LENGTH | head -n 1
}

Test One:

MyRadomString=$(randomString)
echo "My Radom String: '$MyRadomString'";

# Output:
My Radom String: 'a2d6sd';

Test Two:

MyRadomString=$(randomString 8)
echo "My Radom String2: $MyRadomString";

# Output:
My Radom String2: 'S2sP6sk7';

Only update the lock file hash after updating the version of your own package

Only updates the lock file hash to suppress warning about the lock file being out of date.

Rewrite the lock and autoloaders, but otherwise will keep everything that's installed as is.

 composer update --lock 

OR

composer update nothing

Regular expression to filter the float value with minimum maximum length before and after the decimal

The below javascript example shows whether the given input has float value with limited length numbers before (min 2 to max 5) and after (2) the decimal point .

The Regix is : /^([0-9]{2,5}\.?[0-9]{2})$/

 
function isFloat(input)
{
  var regxExp = /^([0-9]{2,5}\.?[0-9]{2})$/
 var result = input.search(regxExp);
  console.log('Is '+ input + ' valid float number: ', result);
  
  return (result < -1) ? true : false;
}

var input = '312g37.78';
var result = isFloat(input);
console.log('Is '+ input + ' valid float number: ', result);

// Output (FALSE due to invalid letter)
Is "312s37.78" valid float number:  false

var input = '312327.782';
var result = isFloat(input);
console.log('Is '+ input + ' valid float number: ', result);

// Output: (FALSE due to invalid length)
Is "312327.782" valid float number:  false

var input = '3.78';
var result = isFloat(input);
console.log('Is "'+ input + '" valid float number: ', result);
// Output: (FALSE due to invalid length which is less than two (before the decimal point))
Is "3.78" valid float number:  false

var input = '31237.78';
var result = isFloat(input);
console.log('Is '+ input + ' valid float number: ', result);
// Output
Is "31237.78" valid float number:  true

var input = '317.78';
var result = isFloat(input);
console.log('Is "'+ input + '" valid float number: ', result);
// Output
Is "317.78" valid float number:  true

Gitlab cloning other dependent private repositories during ci pipeline

If we need to clone any other private repositories during the GitLab `ci` pipeline process, we can use the below command to run the on the `bash` script to copy the source code from another project.

The Job environment variable CI_JOB_TOKEN can be used to authenticate any clones of dependent repositories. For example:

git clone https://gitlab-ci-token:${CI_JOB_TOKEN}@gitlab.com/myuser/mydependentrepo



It can also be used for system-wide authentication (only do this in a docker container, it will overwrite ~/.netrc):

echo -e "machine gitlab.com\nlogin gitlab-ci-token\npassword ${CI_JOB_TOKEN}" > ~/.netrc

Generating the Laravel/Lumen Migrations from ER Diagram Model using MySQLWorkbench

To install the Migration Exporter from MySQL Workbench

Install thehttps://github.com/beckenrode/mysql-workbench-export-laravel-5-migrations/blob/master/export-laravel-5-migrations.py from Workbench > Scripting > Install Plugin/Module and browse the `export-laravel-5-migrations.py` file.

Then, go to Workbench > Tools > Catalog > Export Laravel 5 Migration and click on "Save the Migrations to the Folder..."

However got the following error: (Workbench > Help > Show Log File)

Error during "Export Laravel 5 Migration" 

Then, review the relationship index and foreign keys relations and amended few foreign keys which are not properly selected the reference columns.

Afterwards, tried generating the migration using above method, ultimately able to generate the migration.

However, found missing foreign keys relationship generated migration files.

To generate Laravel Migrations from MySQL Workbench:

To build the migrations with foreign constrains using following steps:

1. Export the model using MySQL Workbench > File > Export > Forward Engineer approach as sample_database.sql file
2. Create the database called 'sample_database'.
3. Next, Import the sample_database.sql file into the above created database to build tables, which will populate all tables from the script. (you can also directly execute all the scripts from that .sql file instead, from the Query Builder)
   Note: Please make sure all the foreign keys relationships are created along with tables, once you find all the relationship are in place.
4. Then, go to the MySQL Workbench > Database > Reverse Engineer, and establish the connection and select the database to regenerate the Model (ERD).
   This allows the MySQL Workbench to propagate the Tables' objects correctly which supports to generate the migrations.
5. Lastly, go to Workbench > Tools > Catalog > Export Laravel 5 Migration and click on "Save the Migrations to the Folder..."
   If you already haven't install the Laravel 5 Migration plugin, refer above.

To prevent pushing the file permission in local into git repo (MacOS)

After switching to MacOS, I had to change the my applications's files permissions due to MAC permissions issue to run the application.

Afterwards, I made a commit and pushed to the Git Repo, however the modified file's permission also included on the push to the Git Repo.

Indeed, I do not want to include those permission which I have done for my local only and I have to reset my commit on the remote repo.

To prevent happening that, please follow the steps below:

1. Check the filemode status on git config:

$ git config -l

Output may contain below:

$ core.filemode=true

2. If it set as true, run the below command to set to false which will prevent including the file permission on the commits.

$ git config core.filemode false

3. Instead, run below command if you want to change the git configuration globally to apply on all the applications:

$ git config --global core.filemode false

         * @param  string  $patha
         * @return string
         */
        function config_path($path = '')
        {
            return app()->basePath() . DIRECTORY_SEPARATOR . 'config'.($path ? DIRECTORY_SEPARATOR.$path : $path);
        }
    }
    

* Add the following code into the `composer.json` inside the `autoload` after the `psr-4`
