RABL (Ruby API Builder Language) is a ruby templating system for rendering resources in different format (JSON, XML, BSON, ...). You can find documentation [here](http://github.com/nesquena/rabl).
|
||||
|
||||
rabl-rails is **faster** and uses **less memory** than the standard rabl gem while letting you access the same features. There are some slight changes to do on your templates to get this gem to work but it should't take you more than 5 minutes.
|
||||
RABL-rails only target Rails 3+ application because Rails 2 applications are becoming less and less present and will be obsolete with Rails 4. So let's look to the future !
|
||||
|
||||
rabl-rails only targets **Rails 3+ application** and is compatible with mri 1.9.3, jRuby and rubinius.
|
||||
So now you ask why used `rabl-rails` if `rabl` already exists and supports Rails. Rabl-rails is *faster* and uses * less memory* than standard rabl gem while letting you access same features. Of course, there are some slight changes to do on your templates to get this gem to work but it should't take you more than 5 minutes.

@ -81,212 +81,4 @@ The same rule applies for view helpers such as `current_user`
|
||||
|
||||
After the template is compiled into a hash, Rabl-rails will use a renderer to do the actual output. Actually, only JSON and XML formats are supported.
|
||||
|
||||
## Configuration
|
||||
|
||||
RablRails works out of the box, with default options and fastest engine available (oj, libxml). But depending on your needs, you might want to change that or how your output looks like. You can set global configuration in your application:
|
||||
|
||||
```ruby
|
||||
# config/initializers/rabl_rails.rb
|
||||
RablRails.configure do |config|
|
||||
# These are the default
|
||||
# config.cache_templates = true
|
||||
# config.include_json_root = true
|
||||
# config.json_engine = :oj
|
||||
# config.xml_engine = 'LibXML'
|
||||
# config.use_custom_responder = false
|
||||
# config.default_responder_template = 'show'
|
||||
end
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Data declaration
|
||||
|
||||
To declare data to use in the template, you can use either `object` or `collection` with the symbol name or your data.
|
||||
|
||||
```ruby
|
||||
# app/views/users/show.json.rabl
|
||||
object :@user
|
||||
|
||||
# app/views/users/index.json.rabl
|
||||
collection :@users
|
||||
```
|
||||
|
||||
You can specify root label for the collection using hash or `:root` option
|
||||
|
||||
```ruby
|
||||
collection :@posts, root: :articles
|
||||
#is equivalent to
|
||||
collection :@posts => :articles
|
||||
|
||||
# => { "articles" : [{...}, {...}] }
|
||||
```
|
||||
|
||||
There are rares cases when the template doesn't map directly to any object. In these cases, you can set data to false or skip data declaration altogether.
|
||||
|
||||
```ruby
|
||||
object false
|
||||
node(:some_count) { |_| @user.posts.count }
|
||||
child(:@user) { attribute :name }
|
||||
```
|
||||
|
||||
If you use gem like *decent_exposure* or *focused_controller*, you can use your variable directly without the leading `@`
|
||||
|
||||
```ruby
|
||||
object :object_exposed
|
||||
```
|
||||
|
||||
You can even skip data declaration at all. If you used `respond_with`, rabl-rails will render the data you passed to it.
|
||||
As there is no name, you can set a root via the `root` macro. This allow you to use your template without caring about variables passed to it.
|
||||
|
||||
```ruby
|
||||
# in controller
|
||||
respond_with(@post)
|
||||
|
||||
# in rabl-rails template
|
||||
root :article
|
||||
attribute :title
|
||||
```
|
||||
|
||||
### Attributes / Methods
|
||||
|
||||
Basic usage is to declared attributes to include in the response. These can be database attributes or any instance method.
|
||||
|
||||
```ruby
|
||||
attributes :id, :title, :to_s
|
||||
```
|
||||
|
||||
You can aliases these attributes in your response
|
||||
|
||||
```ruby
|
||||
attributes title: :foo, to_s: :bar
|
||||
# => { "foo" : <title value>, "bar" : <to_s value> }
|
||||
```
|
||||
|
||||
### Child nodes
|
||||
|
||||
You can include nested information from data associated with the parent model. You can also alias these associations.
|
||||
For example if you have a `Post` model that belongs to a `User`
|
||||
|
||||
```ruby
|
||||
object :@post
|
||||
child(user: :author) do
|
||||
attributes :name
|
||||
end
|
||||
# => { "post" : { "author" : { "name" : "John D." } } }
|
||||
```
|
||||
|
||||
You can also use arbitrary data source with child nodes
|
||||
```ruby
|
||||
child(:@users) do
|
||||
attributes :id, :name
|
||||
end
|
||||
```
|
||||
|
||||
### Custom nodes
|
||||
|
||||
You can create custom node in your response, based on the result of the given block
|
||||
|
||||
```ruby
|
||||
object :@user
|
||||
node(:full_name) { |u| u.first_name + " " + u.last_name }
|
||||
# => { "user" : { "full_name" : "John Doe" } }
|
||||
```
|
||||
|
||||
You can add the node only if a condition is true
|
||||
|
||||
```ruby
|
||||
node(:email, if: -> { |u| u.valid_email? }) do |u|
|
||||
u.email
|
||||
end
|
||||
```
|
||||
|
||||
Nodes are evaluated at the rendering time, so you can use any instance variables or view helpers inside them
|
||||
|
||||
```ruby
|
||||
node(:url) { |post| post_url(post) }
|
||||
```
|
||||
|
||||
Custom nodes are really usefull to create flexible representations of your resources.
|
||||
|
||||
### Extends & Partials
|
||||
|
||||
Often objects have a basic representation that is shared accross different views and enriched according to it. To avoid code redundancy you can extend your template from any other RABL template.
|
||||
|
||||
```ruby
|
||||
# app/views/users/base.json.rabl
|
||||
attributes :id, :name
|
||||
|
||||
# app/views/users/private.json.rabl
|
||||
extends 'users/base'
|
||||
attributes :super_secret_attribute
|
||||
```
|
||||
|
||||
You can also extends template in child nodes using `partial` option (this is the same as using `extends` in the child block)
|
||||
|
||||
```ruby
|
||||
collection @posts
|
||||
attribute :title
|
||||
child(:user, partial: 'users/base')
|
||||
```
|
||||
|
||||
Partials can also be used inside custom nodes. When using partial this way, you MUST declare the object associated to the partial
|
||||
|
||||
```ruby
|
||||
node(:location) do |user|
|
||||
{ city: user.city, address: partial('users/address', object: m.address) }
|
||||
end
|
||||
```
|
||||
|
||||
### Nesting
|
||||
|
||||
Rabl allow you to define easily your templates, even with hierarchy of 2 or 3 levels. Let's suppose your have a `thread` model that has many `posts` and that each post has many `comments`. We can display a full thread in a few lines
|
||||
|
||||
```ruby
|
||||
object :@thread
|
||||
attribute :caption
|
||||
child :posts do
|
||||
attribute :title
|
||||
child :comments do
|
||||
extends 'comments/base'
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
### Render object directly
|
||||
|
||||
There are cases when you want to render object outside Rails view context. For instance to render objects in the console or to create message queue payloads. For these situations, you can use `RablRails.render` as show below:
|
||||
|
||||
```ruby
|
||||
Rabl.render(object, template, :view_path => 'app/views', :format => :json) #=> "{...}"
|
||||
```
|
||||
|
||||
You can find more informations about how to use this method in the [wiki](http://github.com/ccocchi/rabl-rails/wiki/Render-object-directly)
|
||||
|
||||
### Other features
|
||||
|
||||
You can find more informations about other features (caching, custom_responder, ...) in the [WIKI](https://github.com/ccocchi/rabl-rails/wiki)
|
||||
|
||||
## Performance
|
||||
|
||||
Benchmarks have been made using this [application](http://github.com/ccocchi/rabl-benchmark), with rabl 0.7.6 and rabl-rails 0.3.0
|
||||
|
||||
Overall, Rabl-rails is **20% faster and use 10% less memory**, even **twice faster** when using extends.
|
||||
|
||||
You can see full tests on test application repository.

Want to add another format to Rabl-rails ? Checkout [JSON renderer](http://github.com/ccocchi/rabl-rails/blob/master/lib/rabl-rails/renderers/json.rb) for reference
|
||||
Want to make another change ? Just fork and contribute, any help is very much appreciated. If you found a bug, you can report it via the Github issues.
|
||||
|
||||
## Original idea
|
||||
|
||||
* [RABL](http://github.com/nesquena/rabl) Standart RABL gem. I used it a lot but I needed to improve my API response time, and
|
||||
since most of the time was spent in view rendering, I decided to implement a faster rabl gem.
