Leolay Generators

A layout and customized scaffold generator for Rails to combine with active admin gem It generates the layout, the style, the internationalization and it helps you to startup active_admin gems

Compatibility

This version has been tested on Rails 4.2 to 5.0.beta2 and Ruby 2.2.3 on Windows OS and Linux Click on Travis badge for more details. For previous version go to the bottom of this read me.

Install

gem install active_leonardo

or

rails new ActiveLeo -m https://db.tt/gPe6A0l9

or click here to download the template.

You can also get it from the gem root folder

Usage

Once you install the gem, the generators will be available to all Rails applications on your system.

To run the generator, go to your rails project directory and type to generate the layout:

rails generate leolay

Then type to generate the resource:

rails generate leosca

You can revert:

rails destroy leosca

You can generate and destroy more times until you will get your prototype.

Read the follow Step by step paragraph and the next Massive resources generation

Step by step

1. Create the app and the layout:

   rails new ActiveLeo -m YOUR_TEMPLATE_PATH (see above: install paragraph)
   

   Answer y to all gems you need. After the questions it will start generations. If it is the first generation there will be a conflict on locales/en.yml, type y to overwrite.

   Will be:

   • Created a default layout like active admin
   • Created i18n files
   • Created user management on active admin
   • Customized application.rb to exclude javascript and stylesheet for every resource you will create

2. You will get an application ready to work, run:

   rake db:migrate
   rake db:seed
   

   then

   rails s
   

   and try it on http://localhost:3000

   If you get this message:

   undefined local variable or method `new_user_registration_path'

   be sure user model have :registerable devise's module otherwise add it into user model or you have to remove registerable code from

   app\views\application\_session.html.erb
   

   You can login as three different profiles as set in db\seeds.rb:

   1. [email protected], password: abcd1234 [this profile can do everything]

   2. [email protected], password: abcd1234 [can read, create, update and destroy]

   3. [email protected], password: abcd1234 [can read, create and update]

   There is a fourth profile for guest users who can only see the data. In addition to these you can create all the profiles you need according to cancan rules.

3. Create your resource as this example:

   rails g leosca product name:string description:text active:boolean items:integer price:decimal
   

   This will act as a normal scaffold and has more new features:

   1. will be invoked new leosca_controller which is a customized scaffold_controller
   2. attributes will be insert into i18n files for a quick translation
   3. seeds will be created for you to populate new table
   4. invoke active admin generator to add the new resource with a custom configuration to work with cancan

Draper is not directly supported but if you have installed it will be triggers in the resource generation chain.

4. Apply to db:

   rake db:migrate
   rake db:seed
   

That's all!

Other examples:

leolay:

rails generate leolay
rails generate leolay --skip-authentication --skip-authorization

leosca:

rails generate leosca product name:string
rails generate leosca product name:string --skip-seeds
rails generate leosca product name:string --seeds=60          => if you need more records

Massive resources generation

Write the resources you want to generate into the file scaffold.txt and put it in the root. A line for every resource, starting from the beginning with the name as you would do with the scaffold.

If the line is not a resource but another generator, you can simply starting with the full rails command.

Example:

# This is the main resource... (but i could change my mind)
activity user:references name:string{100} body:text completed:boolean percentage_progression:integer{1}
# completed: when all sub tasks are completed
# Any other comments about fields

# This table acts as...
task user:references activity:references name:string{100} body:text completed:boolean percentage_progression:integer{1} deadline_date:date

# I decided to add this because...
rails g migration AddFooToActivity foo:boolean

# I need this because...
rails g migration AddBarToTask bar:boolean

then let active leonardo work for you:

rails generate leosca:massive

and check the report:

create ...
insert ...
append ...
etc ...
---------------------------------------------
Generations started at 18:07:45
18:07:46 - generations ended in 1 second(s)
4 generations executed
9 lines discarded (comments etc.)
---------------------------------------------

of course you can even revert:

rails destroy leosca:massive

This is very useful for a rapid prototyping and if you keep it updated you can use it as information center about the database.

If you try that example remember to add the traslation of the two field foo and bar (added by migrations), otherwise you will get a translation error.

Customization

You could also customize leonardo templates both views and controller. To copy under your project folder run:

rails g leosca:install

Then go to

lib\generators\erb

to edit erb views like you would do with original scaffold. Go to

lib\generators\rails

if you want to customize more.

For more information about usage:

rails g leolay --help
rails g leosca --help

Available layout

Currently the only one available is provided by ActiveAdmin

• active [default]

How to test this project locally

Download this project and go inside the folder

Install the bundle wherever you want:

bundle install --path=mybundle

Check current tasks typing:

rake -T

rake active:tests:all[inspection,rails_versions]  # Tests all rails versions
rake active:tests:newapp[inspection,rails]        # Creates a test rails ap...
rake active:tests:prepare[rails,path]             # Prepare the environment...

If you want to test everything we planned

rake active:tests:all[inspection]

if you pass the argument inspection you can check the application under the test folder:

test/TestApp_xxx_42
...

where xxx is the current ruby version and the last number the rails version. Remember everytime you run a test that folders will be deleted and recreated.

Every rails version has its own bundle under ActiveLeonardo\mybundle_xx folder.

If you want to specify the rails version type:

rake active:tests:all[inspection,4.2]

or multiple versions

rake active:tests:all[inspection,4.1-4.2]

you may also specify your rails as ENV variables, for example on windows:

set CI_RAILS=4.2
bundle install --path=mybundle_42
rake active:tests:newapp[inspection,4.2]

Do NOT exec rake tests from bundle to avoid its bubble.
