Laravel 6 Web Application for Crowdsourcing Projects and Questionnaires

Project URL

Installation Instructions:

First time install (setup database and install dependencies)

  1. Make sure php 7.2 (or newer) is installed.

Install graphics library

 sudo apt-get install php7.2-gd
  1. After cloning the project, create an .env file (should be a copy of .env.example), containing the information about your database name and credentials. Then run php artisan migrate to create the DB schema and php artisan db:seed --class=DatabaseSeederRunOnEmptyDB in order to insert the starter data to the DB

  2. Install laravel/back-end dependencies

composer install

  1. Install front-end dependencies
npm install
  1. Create symbolic link for uploaded images By default images are stored at app/storage/public. Run
php artisan storage:link

to link this folder with the public directory

Apache configuration:

% sudo touch /etc/apache2/sites-available/crowdsourcing.conf
% sudo nano /etc/apache2/sites-available/crowdsourcing.conf
<VirtualHost *:80>
        ServerName dev.crowdsourcing
        ServerAlias dev.crowdsourcing
        DocumentRoot "/home/path/to/project/public"
        <Directory "/home/path/to/project/public">
            Require all granted
            AllowOverride all
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined


Make the symbolic link:

% cd /etc/apache2/sites-enabled && sudo ln -s ../sites-available/crowdsourcing.conf

Enable mod_rewrite, mod_ssl and restart apache:

% sudo a2enmod rewrite && sudo a2enmod ssl && sudo service apache2 restart

Fix permissions for storage directory:

sudo chown -R user:www-data storage
chmod 775 storage
cd storage/
find . -type f -exec chmod 664 {} \;
find . -type d -exec chmod 775 {} \;

Change hosts file so dev.crowdsourcing points to to localhost

sudo nano /etc/hosts       dev.crowdsourcing

Social Login - Sign Up with Socialite

This app uses Socialite Laravel Plugin to handle social login.

In order to get it working in your development environment, you need to make sure that you have API keys and secrets for Facebook and Twitter (guides here and here), and that you can access https://dev.crowdsourcing/ (notice the https) on your machine.

A guide for enabling https on your local machine can be found here.

Basically, you need to run

openssl req -new -sha256 -newkey rsa:2048 -nodes \
-keyout dev.crowdsourcing.key -x509 -days 365 \
-out dev.crowdsourcing.crt

And then reference the 2 files generated in the crowdsourcing.conf file of the application. Make sure you change the port to 443 as shown below:

% sudo touch /etc/apache2/sites-available/crowdsourcing.conf
% sudo nano /etc/apache2/sites-available/crowdsourcing.conf
<VirtualHost *:443>
	SSLEngine on
	SSLCertificateFile "/etc/apache2/sites-available/dev.crowdsourcing.crt"
	SSLCertificateKeyFile "/etc/apache2/sites-available/dev.crowdsourcing.key"

        ServerName dev.crowdsourcing
        ServerAlias dev.crowdsourcing
        DocumentRoot "/home/path/to/project/public"
        <Directory "/home/path/to/project/public">
            Require all granted
            AllowOverride all
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

Also, make sure to restart Apache, by running

sudo service apache2 restart

touch storage/database_testing.sqlite

php artisan migrate --database=sqlite_testing

php artisan db:seed --database=sqlite_testing --class=DatabaseSeederRunOnEmptyDB
