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
This version has been tested on Rails
4.2 and Ruby
2.1.7 on Windows OS and Linux
Click on Travis badge for more details.
gem install active_leonardo
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
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:
rails generate leolay || rails destroy leolay rails generate leosca || rails destroy leosca
You can run it more times and right like scaffold, it's smart and won't generate tons of identical code (thanks thor)
Warning: Leosca destroy do not remove variables parts inserted into feed like time values.
Step by step
Firstly, create layout and initialize your project:
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.
- Created a default layout like active admin
- Created i18n files
- Created user management on active admin
You will get an application ready to work, run:
rake db:migrate rake db:seed
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
You can login as three different profiles as set in db\seeds.rb:
email@example.com, password: abcd1234 [this profile can do everything]
firstname.lastname@example.org, password: abcd1234 [can read, create, update and destroy]
email@example.com, 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.
Create your resource:
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:
- will be invoked new leosca_controller which is a customized scaffold_controller
- attributes will be insert into i18n files for a quick translation
- seeds will be created for you to populate new table
- invoke active admin generator to add the new resource with a custom configuration to work with cancan
Apply to db as always you do:
rake db:migrate rake db:seed
That's all! The new application is ready to be customized to suit your needs:
- start to develop user front end
- take advantage of active admin and its dsl to quickly setup administration section
You could also customize leonardo templates both views and controller. To copy under your project folder run:
rails g leosca:install
Then go to
to edit erb views like you would do with original scaffold. Go to
if you want to customize more.
For more information about usage:
rails g leolay --help rails g leosca --help
rails generate leolay rails generate leolay --skip-authentication --skip-authorization
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
if you made a mistake and want to start from scratch just replace generate with destroy to remove all files and inserted code
Of course, these options are in addition to those provided by the original scaffold
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 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
if you pass the argument inspection you can check the application under the test folder:
test/TestApp_xxx_32 test/TestApp_xxx_40 test/TestApp_xxx_41 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:
or multiple versions
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.
It should work but has not been tested
Rails 2 and Rails 3.0.x
This Generators does not work with versions earlier 3.1
