The super fantastic way of getting Gravatars. By [The Poacher](http://thelincolnshirepoacher.com).
In less than a minute you can add Gravatars to your Ruby project. It works in Rails, Merb & Sinatra.
The best way to learn more about Gravtastic is to [look through the annotated source](http://chrislloyd.github.com/gravtastic). It's one file, about 80 LOC and really pretty simple. If that isn't for you, then follow the instructions below!
## Install
sudo gem install gravtastic
## Usage
For this example I'm going to assume you are using Rails. Don't worry if you aren't, the concepts are still the same.
First off, add this to your `Gemfile`:
gem 'gravtastic'
Next, in your model:
class User < ActiveRecord::Base
include Gravtastic
gravtastic
end
_Note: You can use either `is_gravtastic!`, `is_gravtastic` or `has_gravatar`, they all do the same thing._
And you are done! In your views you can now use the `#gravatar_url` method on instances of `User`:
<%= image_tag @user.gravatar_url %>
Gravatar gives you some options. You can use them like this:
<%= image_tag @user.gravatar_url(:rating => 'R', :secure => true) %>
That will show R rated Gravatars over a secure connection. If you find yourself using the same options over and over again, you can set the Gravatar defaults. In your model, just change the `is_gravtastic` line to something like this:
gravtastic :secure => true,
:filetype => :gif,
:size => 120
Now all your Gravatars will come from a secure connection, be a GIF and be 120x120px.
Gravatar needs an email address to find the person's avatar. By default, Gravtastic calls the `#email` method to find this. You can customise this.
gravtastic :author_email
### Defaults
A common question is "how do I detect wether the user has an avatar or not?" People usually write code to perform a HTTP request to Gravatar to see wether the gravatar exists. This is certainly a solution, but not a very good one. If you have page where you show 50 users, the client will have to wait for 50 HTTP requests before they even get the page. Slooww.
The best way to do this is to set the `:default` option when using `#gravatr_url`. If the user doesn't have an avatar, Gravatar essentially redirects to the "default" url you provide.
### Complete List of Options
Option |
Description |
Default |
Values |
|
secure |
Gravatar transmitted with SSL |
true |
true/false |
size |
The size of the image |
80 |
1..512 |
default |
The default avatar image |
none |
"identicon", "monsterid", "wavatar" or an absolute URL. |
rating |
The highest level of ratings you want to allow |
G |
G, PG, R or X |
filetype |
The filetype of the image |
png |
gif, jpg or png |
### Other ORMs
Gravatar is really just simple Ruby. There is no special magic which ties it to one ORM (like ActiveRecord or MongoMapper). You can use the following pattern to include it anywhere:
require 'gravtastic'
class MyClass
include Gravtastic
is_gravtastic
end
For instance, with the excellent [MongoMapper](http://github.com/jnunemaker/mongomapper) you can use do this:
class Person
include MongoMapper::Document
include Gravtastic
is_gravtastic
key :email
end
And wallah! It's exactly the same as with ActiveRecord! Now all instances of the `Person` class will have `#gravatar_url` methods.
_Note: the `#gravatar_url` methods don't get included until you specify the class `is_gravtastic!`_
## Javascript
_Note: this feature requires Rails 3.1 & CoffeeScript._
Web applications are increasingly performing client side rendering in Javascript. It's not always practical or clean to calculate the `gravatar_url` on the server. As of version 3.2, Gravtastic comes bundled with Javascript helpers.
If you are using Rails 3.1 you can simple require Gravtastic in your `Gemfile` and add
//= require gravtastic
in your `application.js` file. This will include a function, `Gravtastic` which performs similarly to `gravtastic_url`.

> Gravtastic('christopher.lloyd@gmail.com', {default: 'identicon', size: 64})
"https://secure.gravatar.com/avatar/08f077ea061585744ee080824f5a8e65.png?r=PG&d=identicon&s=64"
## Making Changes Yourself
Gravtastic is a mature project. There isn't any active work which needs to be done on it, but I do continue to maintain it. Just don't expect same day fixes. If you find something that needs fixing, the best way to contribute is to fork the repo and submit a pull request.
git clone git://github.com/chrislloyd/gravtastic.git
