Validates_numericality_of simply not working

Rails
1

validates_numericality_of is returning “is not a number” for everything
I try. What’s up?

database:
column: price
type: float (9,2) (I’ve also tried decimal 9,2)

model:
validates_numericality_of :price, :only_integer => false

console:
p = Product.new
p.price = “3.25”
p.save

p.errors.to_yaml:

errors:
price:

  • is not a number

I went digging through the Rails source to get the exact exception and I
get:

invalid value for Float(): “”

The line:
Kernel.Float(record.send("#{attr_name}_before_type_cast").to_s)

record.send("#{attr_name}_before_type_cast").to_s # => ‘’

This is too basic… so I must be doing something stupid. Even updated
Rails:

gem update rails

Updating installed gems…
Attempting remote update of rails
Successfully installed rails-1.1.6
Gems: [rails] updated

…any ideas?

p.price = “3.25”

you are trying to set price to a string object.
p.price = 3.25
or I suppose
p.price = “3.25”.to_f

No, that’s not it. If you look at the code that does the conversion:

Kernel.float( … ), it takes a string argument.

Aha, it was the flex_attributes plugin that broke it. I’ll have to email
the author.
