Please find the validation script below to fix the username validation allowing it to have only Alphanumeric with dot (.), dash/hypen (-) and underscore(_).

$validator = Validator::make($request->all(),
            ['user_name' =>
                ['required', 'min:4', 'max:20', 'unique:auth_users', 'Regex:/^[a-zA-Z0-9-._]+$/']

Configure the Project Specific Git Author/User Credential

If you working for two projects (may be one for work specific and another personal project) and you would like to configure the Git Author/User credential different for both, I mean as a project specific rather than as a global one.

You may have configured or can set as global credential as:

# To check the git configuration
git config -l

# To set the global git configuration
git config --global user.name "RC"
git config --global user.email "rc@example.com"

Now to change the credential for a project. First go the the project branch and check what's the credential it has and override with new credential using below command

# Go to the project folder first and make sure you already have git initiated.
cd ~/apps/project_folder

# To check the git configuration
git config -l

# To overwrite the name
git config user.name "RC Pro"

# To overwrite the email
git config user.email "personal@example.com"

Then, you all set for that.

Translate input and replace the variable afterwards on the string with variable placeholder ie. [variable].

First create AngularJs filter fiel called translate-input-var-and-replace.js and save with below content:

List of Laravel Artisan Shortcuts (Alias) for Windows and MacOS

I would like to share the list of command alias I have created on my local to minimise the keystrokes with the Team.

alias cda="composer dump-autoload"; alias ci="composer install"; alias cu="composer update"; alias bi="bower install"; alias bu="bower update"; alias gi="gulp install"; alias ni="npm install"; alias pa="php artisan"; alias pam="php artisan migrate"; alias pamr="php artisan migrate:rollback"; alias pads="php artisan db:seed"; alias pades="php artisan db-exporter:seed"; alias pamm="php artisan make:migration"; alias pamc="php artisan make:controller"; alias pammd="php artisan make:model"; alias t="phpunit"; alias dat="php artisan app:droptables"; alias ga="git add"; alias gaa="git add ."; alias gc="git commit -m"; alias gp="git push"; alias gs="git status"; alias gl="git log"
