Couchrest_model method to verify if attribute changed (dirty)

[Lucas Renan]

Anyone knows if Couchrest model supports some verification for
attributes changes? like ar dirty:

person = Person.find_by_name('uncle bob')
person.changed? # => false
person.name = 'Bob'
person.changed? # => true
person.name_changed? # => true
person.name_was # => 'uncle bob'
person.name_change # => ['uncle bob', 'Bob']
person.name = 'Bill'
person.name_change # => ['uncle bob', 'Bill']

Hi,

This has been attempted a couple of times in the past, but performance issues and the problem with dealing with nested models always sets it back.

The following pull request looks very promising if you want to check it out, I've had other priorities recently but I hope to check it out soon:

Cheers,

sam

Hi Sam,

thanks for your reply,
this kind of issue related with performance is really complicated.

In the case, I'm building a lib to create slugs. Then, slugs can not
be regenerated if property has not been changed.
Maybe I'll add some type of verification while this feature is not
added to the project.

Hi Lucas,

Your question yesterday prompted me to have another look at the pull request I mentioned. I actually tested it out, made a few minor modifications and included it in the 1.1.0.beta4 release.

Check it out, you should be able to do a @model.title_changed? without problem, and performance seems to be fine.

Cheers,

sam
