Messages with rails activeresource

I have a quick question about the active resource. If I have a user resource when I call like

User.find(1).put(:promote, :position => 'manager')

According to the api it translates this call / users / 1 / promote.xml? Position = manager

My question is that. Does activeresource actually make two calls here? find the get execution then cast on that object or add app.put to .find means it just makes one call. If so, then the only reason for .find is to specify the correct URL format for / users /: id / promotion ??

I couldn't find in the docs where this could be stated, but it's .find, which makes me think maybe there are two service calls happening?

If ActiveResource works like ActiveRecord, I would say yes. If you do something like

Foo.find(1).update_attributes(:name=>"Bar")


ActiveRecord first performs a selection to retrieve the object and then issues an update call to the database to update the record. I would suggest that ActiveResources functions in a similar way where it makes two web service calls to get the object and then updates the object.

Put the following words in your inners:

class ActiveResource::Connection
  #   Creates new Net::HTTP instance for communication with
  #   remote service and resources.
  def http
    http = Net::HTTP.new(@site.host, @site.port)
    http.use_ssl = @site.is_a?(URI::HTTPS)
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE if http.use_ssl
    http.read_timeout = @timeout if @timeout
    #Here the addition that allows you to see the output
    http.set_debug_output $stderr
    return http
  end
end


Search for "http.set_debug_output $ stderr" "ActiveResource" to find the original author of this helpful tip.
