Survloop is a Laravel-based engine for websites dominated by the collection and publication of open data. This is a database design and survey generation system, though it will increasingly be a flexible tool to solve many web-based problems.

It is currently in continued, heavy development, with much happening here in 2021, almost ready to go live. I plan to provide more documentation in the coming weeks. Thank you for your interest and patience!

This software was originally developed to build the Open Police system. It began as an internal tool to design our database, then prototype survey generation. Then it was adapted to the Laravel framework, and has continued to grow towards a content-management system for data-focused websites.

The upcoming Open Police web app is the best live install of the engine, and feedback on that project and the Survloop user experience can be via the end of the submission process: The resulting database designed using the engine, as well as the branching tree which specifies the user's experience: /db/OP /tree/complaint Among other methods, the resulting data can also be provided as XML included an automatically generated schema, eg. /complaint-xml-schema /complaint-xml-example /complaint-xml-all

The installation used for is currently the best example of a bare-bones extension of Survloop:


Getting Started

Install Laravel & Survloop on Homestead

Full install instructions also describe how to set up a development environment using VirutalBox, Vargrant, and Laravel's Homestead. For these instructions, the new project directory is 'survproject'.

% composer create-project laravel/laravel survproject "8.5.*"
% cd survproject

Edit these lines of the environment file to connect the default MYSQL database:

% nano .env
APP_NAME="My Survloop Project"


Next, install Laravel's out-of-the-box user authentication tools, and Survloop:

% php artisan key:generate
% php artisan cache:clear
% COMPOSER_MEMORY_LIMIT=-1 composer require rockhopsoft/survloop
% nano composer.json

From your Laravel installation's root directory, update composer.json to require and easily reference Survloop:

"autoload": {
    "psr-4": {
        "RockHopSoft\\Survloop\\": "vendor/rockhopsoft/survloop/src/",
        "Predis\\": "vendor/predis/predis/src/",
}, ...

It seems we also still need to manually edit config/app.php:

% nano config/app.php
'providers' => [
'aliases' => [
    'Survloop' => 'RockHopSoft\Survloop\SurvloopFacade',
], ...

If installing on a server, you might also need to fix some permissions before the following steps...

% chown -R www-data:www-data storage bootstrap/cache resources/views database app/Models

Clear caches and publish the package migrations...

% php artisan config:clear
% php artisan route:clear
% php artisan view:clear
% echo "0" | php artisan vendor:publish --force
% composer dump-autoload
% curl http://survproject.local/css-reload

With certain databases (like some managed by DigitalOcean), you may need to tweak the Laravel migration:

% nano database/migrations/2014_10_12_100000_create_password_resets_table.php
% nano database/migrations/2019_08_19_000000_create_failed_jobs_table.php

Add this line before the "Schema::create" line in each file:

\Illuminate\Support\Facades\DB::statement('SET SESSION sql_require_primary_key=0');

Then initialize the database:

$ php artisan migrate
$ php artisan db:seed --class=SurvloopSeeder
$ php artisan db:seed --class=ZipCodeSeeder
$ php artisan db:seed --class=ZipCodeSeeder2
$ php artisan db:seed --class=ZipCodeSeeder3
$ php artisan db:seed --class=ZipCodeSeeder4

Initialize Survloop Installation

Then browsing to the home page should prompt you to create the first admin user account:

If everything looks janky, then manually load the style sheets, etc:

After logging in as an admin, this link rebuilds many supporting files:

Other Package Installation

The Excel tools use maatwebsite/excel, and you might need this on Ubuntu:

$ sudo apt-get install php7.4-zip

...or this on Mac:

$ brew update
$ brew install php@7.4
$ brew link php@7.4 --force

If you plan to generate PDFs, then you should also download and install Ghostscript. This is for Ubuntu, it might already be installed:

$ sudo apt-get install ghostscript

This works in Homestead on Mac, with Homebrew:

$ brew install ghostscript


About Survloop's Codebase and Database Design

Better documentation is juuust beginning to be created...

Once installed, documentation of this system's database design can be found at http://localhost/dashboard/db/all. This system's survey design can be found at http://localhost/dashboard/surv-1/map?all=1&alt=1 or publicly visible links like those above.


Here's the TODO list for the next release (1.0). It's my first time building on Laravel, or GitHub. So sorry.

  • Correct all issues needed for minimum viable product, and launch Open Police Complaints.
  • Integrate options for MFA using Laravel-compatible package.
  • Upgrade database and graphic design for admin tools, thus far only used by the author.
  • Code commenting, learning and adopting more community norms.
  • Add decent levels of unit testing. Hopefully improve the organization of objects/classes.
  • Improve import/export work flow for copying/moving installations.
  • Generate all admin tools by Survloop itself.
  • Add multi-lingual support on the Node-level (surveys and web pages), for starters, then database design.
  • Multi-lingual support at every level.
  • Convert more Survloop (older) code to take advantage of more Laravel built-in icapabilities.
