ViewUtils

ViewUtils is an alternative to rails helpers. Everyone knows rails helpers are shitty, mainly because

they pollute the global view namespace
once added, you have a hard time removing them
it's often not clear in which file they are living
naming them is hard

ViewUtils are as easy as helpers, without the downsides:

<%= util(:user).avatar_image(user) %>

Installation

Add this line to your application's Gemfile:

gem 'view_utils'

And then execute:

$ bundle

Or install it yourself as:

$ gem install view_utils

Usage

To create your own ViewUtil:

class UserUtil < ViewUtils::Base
  include ActionView::Helpers::AssetTagHelper

  def avatar_image(user, size: :small)
    image_tag user.avatar_image(size), class: "avatar-image"
  end
end

In your view:

<%= util(:user).avatar_image(user) %>

To use another util from within your util, you can use the util helper within your utils as well:

class UserUtil < ViewUtils::Base
  # ...

  def some_util
    util(:login).other_util
  end
end

For the rare cases, where you need access to the view object, you can use the view directly:

class UserUtil < ViewUtils::Base
  # ...

  def some_util
    view.root_url
  end
end
