P.save not actually saving

Rails
1

i’m not sure if this is the right place for this but it its an
activerecord issue so hopefully it is.

anyway when ever i try and save a model it come back as true but when i
find the object again it hasn’t changed.

For example:

p = Post.find 1
p.title.capitalize!
p.save # Returns true but doesn’t actually save

the logger outputs the following when i save it

D, [2011-05-17T18:33:55.786908 #5595] DEBUG – : SQL (0.2ms) BEGIN
D, [2011-05-17T18:33:55.787576 #5595] DEBUG – : SQL (0.1ms) COMMIT
=> true

Any reason for this?

Thanks, James.

try (in console)

p = Post.find 1
p.title.capitalize!
p.title
p.save

p.errors.inspect

Thanks very much i had been pondering on this for a while

Final Solution:

p.title = p.title.capitalize
instead of
p.title.capitalize!

Inplace modification of attributes confuses the change tracking in ar -
either don’t do it (ie p.title = p.title.capitalize) or call the
title_will_change! method after you do

or p.update_attribute(:title, p.title.capitalize) and without p.save

or if you want to capitalize in your model (when saving), you could do
that with before filter

before_save do |row|
row.title = row.title.capitalize unless row.title.blank?
end
