I would like to make a Content Management System for my daughter’s nursery. They keep the daily information about the children in notebooks full of very easy to lose post its and hope this app can help with it. The daily information will be referred to as activities.
-Create a repository in Github.
-The project structure following the MVC conventions.
-Set my environment and my config.ru. I am following the Modular Sinatra Pattern and having a
config.ru file is one convention of it. The purpose of config.ru is to detail to Rack (Sinatra gem is built on top of Rack) the environment requirements of the application and start the application, mount my application controllers. Rack is a convention, or specification, that lets web applications “plug” into a common interface for handling HTTP requests. To actually serve requests, we need a web server — something that can translate HTTP requests into Ruby calls. My gem ‘thin’ is a web server that do this job.
-Create my Gemfile with all gems that I am going to run trough Bundle, which is set up in my environment file.
Here are the gems I want to use:
sqlite3: sqlite is a library that implements a SQL database engine. sqlite is my database adapter gem.
thin: it is a web server.
I think that I will need at least 3 models, User, Activity and Student.
Is it works?
I am using Visual Studio Code and after creating the structure of my project with very basic info I tried to run shotgun and was getting the following error:
I had a server running in the background. After trying a lot of different things I could stopped it with the following I found in StackOverflow:
lsof -i :9393 (9393 is the port I ran it on).
I killed the process using
kill -9 *pid*. My pid was: 58152.
When I ran
lsof -i :9393 again, nothing showed up.
I then ran shotgun and everything works fine now.
Enable sessions in your AppController and use the gem bcrypt. Make sure your user model has_secure_password and that on your users table you store the password like “password_digest“.
Protecting the session secret by Martin Fowler:
I changed my configuration to look like this:
The password fails safe to a secure hex value if
SESSION_SECRET is unset.
Create a Database folder (db), run your migrations to create your tables. I have created one table for the students, another table for my users and a last one for the activities.
rake db:create_migration NAME=create_students
rake db:create_migration NAME=create_users
rake db:create_migration NAME=create_activities
Then modify my migration tables according to my needs.
And finally run rake db:migrate, and all your tables will be added.
Play with my models and the database.
I run tux in my console but I got the following error
config.ru does not support require_relative so I changed my link and everything works fine!
Now it is time to be more creative and design my routes in the controllers and my views. I am using Bootstrap.
