Hi  
I have a name field And it has no validation And when I update that  
field with this

!@#$%^&\*()\_+|}{":?\>\<,./;’[]\

## It gives error /usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active\_record/connection\_adapters/postgresql\_adapter.rb:557:in `transaction' /usr/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/transactions.rb:129:in`transaction’

```
   Could anybody please suggest a regex to make pass this?

```

Thanks in advance  
Sijo

Hi Sijo,

I’m sorry but I don’t understand what you are trying to do. Are you  
trying to insert a string representing a regexp in a field in your  
database? Are you trying to validate a value that goes into a field  
with what looks like a regular expression? What do you mean by 'a  
regexp to make pass this? What is “this”?
