Ruby on Rails - Make Slim the Default Template

Question

I am working on a Ruby on Rails project and am needing to customize default views provided by Gems.

The requirement is to use Slim for template. I understand that ERB is the default template engine for Rails.

As per my observation, the priority is for ERB and if not it will use Slim/Haml views.

I am interested in knowing if it is possible to set Slim as the default instead of the ERB?

How can this be achieved so that when I create a local version of a template in Slim it will override the template provided by the gem.

Any clue will be appreciated.

Solution 1

You can use "slim-rails" gem which is built for generating slim template as default.

https://github.com/slim-template/slim-rails

Just replace gem 'slim' by gem 'slim-rails' in your Gemfile.

Solution 2

In you Gemfile, include

gem 'slim-rails'

And to generate slim tempage, in config/application.rb add this line of code

class Application < Rails::Application
........................................

    config.generators do |g|
      g.template_engine :slim
    end
end

Is there a way to add slim within rails new MyProject?

@Basi, when generating new project, there is no view so I don't think you need it. Also there is no Gemfile for adding the gem.

You're right. However there is application.html.erb. But this is easy to change. Thanks for the comment.

@Besi you could achieve this with application templates - guides.rubyonrails.org/rails_application_templates.html

what's the difference between "slim" and "slim-rails"?

@アレックス It looks like "slim-rails" has "slim" has a dependency, but has additional code for configuring Rails generators.

@アレックス slim-rails for rails generates

This got rails generate controller to generate slims instead of erbs, but how do I tell Puma to looks for slims instead of erbs?
