Features

• 🎨 Generative art creation without coding via UI with the selection of pre-programmed patterns and parameters
• 🖥️ Art visualization page with order and comments section
• 🖥️ Art auto-resizing on visualization page without loss of quality using the p5js-svg library
• ✍️ User login and registration using the Devise library
• 🧑 Profile page with arts, comments, orders and earnings of each user

Setup

In the project folder, execute these commands:

$ bundle install # For Ruby gems
$ pnpm install # or npm install -- For NPM modules
$ bundle exec yard gems # for solargraph indexing

After that, you need to create a PostgreSQL database. For that, you need to install the software using your distro's repository (like sudo pacman -S postgresql in Arch Linux) or, if you are on Windows, you need to download it on the official website.

Afterwards, it's required to create a user in the postgres server with the same name of your user account in the computer:

CREATE USER ${your_username};

Henceforth, it's needed to create a database with the name tcc_development with your new database account:

CREATE DATABASE tcc_development OWNER ${your_username};

After that, you can execute the database migration without errors:

$ rails db:migrate

Later, to execute the server, just run:

$ ./bin/dev

With the application running, you can create an admin account by simply registering a new user account. The platform assigns admin privileges for the first registered user.

Troubleshooting

./bin/dev not working on Windows

To avoid this error on Windows, you need to run the commands located in Procfile.dev on your console.

If you are using an environment like MSYS2, open two terminals and run a command on each one:

Rails server:

$ ./bin/rails server -p 3000

Tailwind auto update:

$ ./bin/rails tailwindcss:watch

Error installing gems on Windows

This error occurs when the user decides to do a Ruby system installation instead of a user installation.

To fix that, when running the Ruby Windows installer, don't install Ruby system-wide and, after that, run sysdm.cpl and add an User Variable called GEM_HOME, pointing to your install directory and, also, is required to add a new entry on PATH variable pointing to %GEM_HOME%\bin.

PostgreSQL authentication error

This error happens when the PostgreSQL user doesn't have a password and, also, the project wasn't configured on config/database.yml to connect to a database with a password.

If you are on a local machine and want to access the database on your system without a password, you can edit your PostgreSQL pg_hba.conf to alter the authentication method from scram-sha-256 to trust:

pg_hba.conf - Before

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     scram-sha-256
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     scram-sha-256
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256

pg_hba.conf - After

local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust
