Ruby on rails validation

Question

I figured a way to do validation. I found that inside models, i need to add these lines

validates_presence_of :name validates_uniqueness_of :name

What i'm trying to achieve is for example, i don't want the user to add :;!@#$%^&*() [or special characters] in my text inputs. Need some inputs on this.

Use the :format as described in the docs

You can use format_of:

validates_format_of :name, :with => /\A[a-zA-Z]+([a-zA-Z]|\d)*\Z/

Or create your own validation:

validates :name,
   :presence   => true,
   :format     => { :with => regex } # Here you can set a 'regex'
