Update_attributes and validation

Rails
1

hi all,

I am updating 50 records on one page with update_attributes method

,my validations are

validates_numericality_of :year, :greater_than_or_equal_to => 1900,
:less_than_or_equal_to => 2028, :message => “Year must be between 1900
and 2028”
valdate_presence_of:title
valdate_presence_of:price

id title year price
1 James bond 2008 $100
2 zoro the mask 1978 $ 50
.
.
.
.
50 don 2000 $400

if I provide wrong input for one say year “1800” for “don” and correct
for “james bond” year as “2000” it updates James bond ,correctly but do
not show validation message for “don” on my page. I want to display
message how can i do that

try with update_attributes! (which internally uses ‘save!’)

hi

I have used update_attributes! it shows validation message

ActiveRecord::RecordInvalid in BookController#edit_book

Validation failed: Year should be a above 1900

on different page ,but i want that message must be displayed on same
page on top
my controller look like this

def edit_book
if request.post?

code for update data ie “update_attribute!” method

end
@books = Book.find(:all)
end

and I have view named “edit_book.html.erb”
