Preventing users from using your app name in their name

Rails
1

Is there a Rails validation helper or an easy way of preventing
attributes from containing a certain word match, e.g. you have a User
model, the user has a name attribute, and you don’t want the @user.name
to == ‘MyRailsApp’ or to have ‘MyRailsApp’ somewhere in there?

I imagine it would look something like this (although I can’t get this
one to work - it always fails);

validates_format_of :name, :with => /!MyRailsApp/i, :message => “You
can’t use our Website name.”

Any ideas?

Try this one:

validates_each :name do |record, attr, value|
record.errors.add attr, “can’t use our Website name.” if value =~ /
MyRailsApp/i
end

That one works great, thanks.

Thanks, Phillip. I found validates_exclusion_of soon after posting but,
I couldn’t make it case sensitive.
