Rails On Firebird - status and follow the guide

Rails On Firebird - you need to check that Firebird active record adapter and ruby driver are installed
Install Rails 4.x :
 gem install rails
Generate a new Firebird Rails application
rails new firebird_app 
delete the generated database.yml sqlite config and use the one from bellow
Be aware about indentation
cat config/database.yml

Edit the project Gemfile and add the activerecord-fb-adapter gem:
gem 'activerecord-fb-adapter'
Then run:
bundle update
 rails generate scaffold Client name:string address:string email:string remark:text
  rake db:migrate
I have re-read the ruby guide
so i did these commands while following the official guide
rake db:create
but database was already created in flamerobin
script/generate controller home index
vi app/views/home/index.html.erb
and write something there, start the server with
rails s
and now you can see something in browser

I have created the table and one sequence in firebird db
name VARCHAR(255),
title VARCHAR(255),
content VARCHAR(255),
timestamps timestamp

I have ran the scaffold again to generate the posts model/view/controller
script/generate scaffold Post name:string title:string content:text
and then
started the server
rails s

Of course I have modified the route and added an link as in tutorial and now i can add and modify blog posts
note: in new rails route is defined this way in config/routes.rb
map.root :controller => "home"


Follow the normal ActiveRecord conventions for table names, primary key columns, etc. The one “extra” you’ll need for Firebird is that you’ll have to create a generator for any tables that require a sequence-based primary key. The default naming convention is TABLENAME_SEQ. So if you have a users table, you would need to create a corresponding USERS_SEQ generator

You don't need to create before insert triggers ! rails reads the value from sequence and then increments it in ruby code, Yay!
