ActiveResource#attributes= Clobbers All Values

Reported by Matthew Moore | June 9th, 2008 @ 06:37 PM

Although I'm not entirely sure why from looking at the source, but when I call myresource.attributes = { :attribute => 'value' }, all other attributes disappear from myresource, except for :attribute. I'm using Rails 2.1.0.

>> remote = MyResource.find(1)

=> #<MyResource.0x1f6b64c @prefix_options={}, @attributes={"message"=>"Hello world!", "updated_at"=>Sun Jun 01 00:23:24 UTC 2008, "id"=>1, "urn"=>"1-1", "created_at"=>Sun Jun 01 00:23:24 UTC 2008}>

>> remote.attributes = { :message => "NEW MESSAGE" }

=> {:message=>"NEW MESSAGE"}

>> remote

=> #<MyResource:0x1f6b64c @prefix_options={}, @attributes={:message=>"NEW MESSAGE"}>

attribute= is meant to assign all attributes not a single one. This is the expected behavior. If you're looking to modify the record use update_attributes.

What if you don't want to modify the record remotely, just yet?

E.g. do the following... This is pretty standard controller code, for an ActiveRecord, i would think.

remote = MyResource.find(1) remote.attributes = { :message => "NEW MESSAGE" }

do something else with "remote" before save

remote.xyz_method

if remote.save ... else ... end
