Don't want to implement user avatar uploads but still have basic avatars to distinguish users and brigthen up your app?
Use colorful SVGs as user avatars in any Ruby and Rails application.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install initials
Initials.svg("Morty Smith") anywhere to get a colorful initials avatar SVG as string.
The avatar's background color is based on the provided name and the font-size is adjusted to fit between one and three character initials.
No special configuration is required to work with Ruby on Rails, but for your convinience, you can add this to your
def user_avatar(name, **options) Initials.svg(name, **options) end
Now you can create SVGs in all views:
<%= user_avatar(current_user.name) %>
Initials automatically marks its created SVG strings as
You can pass the following options into
Initials.svg or your
user_avatar(current_user.name, colors: 8, # number of different colors, default: 12 limit: 1, # maximal initials length, default: 3 shape: :rect, # background shape, default: :cirlce size: 96 # SVG height and width in pixel, default: 32 )
Of course, you can also use CSS to make the SVG have different sizes in different places of your HTML.
