Hi, there.
I have two validations in the model:
validates_numericality_of :value, :only_integer=>true,
:allow_blank=>true
validates_size_of :value, :is=>9, :message=>"must be 5-digit
number",
:if=>Proc.new{|u| u.value.is_a?(Numeric)}
They work as expected except when the :value is character/string like
"a" "abc", the second validation will also output error
message "must be
5-digit number". What I want is the second validation displays error
message only when the :value is a number. I think :if=>Proc.new{|u|
u.value.is_a?(Numeric)} would take care of it, but it didn''t.
The second problem is about the custom validation. I got a very simple
custom validation. Whenever there is an error, it catches it and shows
the error message. But the field with error is not highlighted. I
checked the source of the page, the "fieldwitherror" was not generated
on the field checked by the custom validation. I tried the
validation_reflection plugin. It catched the error but there''s no
error
message under the field. Normally that''s where the message should be.
I guess they are related but I am not sure what causes it.
Any help will be appreciated.

I tried that before but it made the second validation stop working. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Maybe the name of the field "value" is causing a conflict somewhere. Try to rename the field to something else just to test. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I tried different names for the field but none of those worked. I just wrote a custom validation to workaround it although still can''t figure it out. Anyone has any idea about the second problem? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

For example, you''re testing whether or not :value is numeric within both validates_* methods. Next, the :is compares the number of bytes and not the number of characters you should be able to do the following: validates_numericality_of :value, :only_integer => true, :allow_blank => true # make sure that it''s an integer validate :number_of_digits # make sure that we have five digits private def number_of_digits unless self.value.to_s.size == 5 errors.add :value, "should be 5 digits" end end Good luck, -Conrad> They work as expected except when the :value is character/string like > "a" "abc", the second validation will also output error message "must be > 5-digit number".

Thank you for the explanation. My workaround looks similar to your code and works. I still have no clue why :if=>Proc.new{...} didn''t work though. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
