Using <object> and <embed> were forbidden for obvious security reasons. Instiki now permits embedding video via the HTML5 <video> element (Ogg/Theora encoded videos only, with .ogg or .ogv extensions). You can even upload videos with [[foo.ogg:video]] Instiki now support x-sendfile. See the Proxying page for configuring Apache (with the x-sendfile module). Lighttpd should work similarly. Update Rails to latest Edge (hopefully converging on RC2!).

# Returns a JSON string representing the model. Some configuration is
|
|
# available through +options+.
|
|
#
|
|
# The option <tt>ActiveRecord::Base.include_root_in_json</tt> controls the
|
|
# top-level behavior of to_json. In a new Rails application, it is set to
|
|
# <tt>true</tt> in initializers/new_rails_defaults.rb. When it is <tt>true</tt>,
|
|
# to_json will emit a single root node named after the object's type. For example:
|
|
#
|
|
# konata = User.find(1)
|
|
# ActiveRecord::Base.include_root_in_json = true
|
|
# konata.to_json
|
|
# # => { "user": {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true} }
|
|
#
|
|
# ActiveRecord::Base.include_root_in_json = false
|
|
# konata.to_json
|
|
# # => {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true}
|
|
#
|
|
# The remainder of the examples in this section assume include_root_in_json is set to
|
|
# <tt>false</tt>.
|
|
#
|
|
# Without any +options+, the returned JSON string will include all
|
|
# the model's attributes. For example:
|
|
#
|
|
# konata = User.find(1)
|
|
# konata.to_json
|
|
# # => {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true}
|
|
#
|
|
# The <tt>:only</tt> and <tt>:except</tt> options can be used to limit the attributes
|
|
# included, and work similar to the +attributes+ method. For example:
|
|
#
|
|
# konata.to_json(:only => [ :id, :name ])
|
|
# # => {"id": 1, "name": "Konata Izumi"}
|
|
#
|
|
# konata.to_json(:except => [ :id, :created_at, :age ])
|
|
# # => {"name": "Konata Izumi", "awesome": true}
|
|
#
|
|
# To include any methods on the model, use <tt>:methods</tt>.
|
|
#
|
|
# konata.to_json(:methods => :permalink)
|
|
# # => {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true,
|
|
# "permalink": "1-konata-izumi"}
|
|
#
|
|
# To include associations, use <tt>:include</tt>.
|
|
#
|
|
# konata.to_json(:include => :posts)
|
|
# # => {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true,
|
|
# "posts": [{"id": 1, "author_id": 1, "title": "Welcome to the weblog"},
|
|
# {"id": 2, author_id: 1, "title": "So I was thinking"}]}
|
|
#
|
|
# 2nd level and higher order associations work as well:
|
|
#
|
|
# konata.to_json(:include => { :posts => {
|
|
# :include => { :comments => {
|
|
# :only => :body } },
|
|
# :only => :title } })
|
|
# # => {"id": 1, "name": "Konata Izumi", "age": 16,
|
|
# "created_at": "2006/08/01", "awesome": true,
|
|
# "posts": [{"comments": [{"body": "1st post!"}, {"body": "Second!"}],
|
|
# "title": "Welcome to the weblog"},
|
|
# {"comments": [{"body": "Don't think too hard"}],
|

# "title": "So I was thinking"}]}
