Validation:  
validates\_presence\_of :name  
validates\_length\_of :name, :maximum =\> 150  
validates\_inclusion\_of :category, :in =\> %w( X Y XY )  
validates\_length\_of :gender, :maximum =\> 3  
validates\_length\_of :tag, :within =\> 1…10

Data sended

data: !map:HashWithIndifferentAccess  
name: Bond  
category: X  
tag: standard

Errors:

Category is not included in the list  
Tag is too short (minimum is 1 characters)  
Gender is too long (maximum is 3 characters)

What wrong?

Category is in list  
Tag can’t be too short, it 8 char  
And gender can’t be too long, because there is no gender value at all.

Try with following

validates\_inclusion\_of :category, :in =\> %w( X, Y, XY )  
validates\_length\_of :gender, :maximum =\> 3, :allow\_nil =\> true  
validates\_length\_of :tag, :in =\> 1…10

You need to install ruby-debug gem first Check if it already installed  
gem list

write debugger at the place where u want debugging and now start  
your server like  
./script/server --debugger then you will get debug prompt Type h for  
help to get available commands  
example : to print any value say @var  
p @var

For tag also you give  
validates\_length\_of :tag, :maximum=\>10 like that and try… you can give  
minimum also in this…
