Here is the test we ran:
test "a user can have a correctly formatted profile name" do
user = User.new(first_name: 'Joel', last_name: 'Crouse', email: 'crousejoel@gmail.com')
user.password = user.password_confirmation = '84948494'
user.profile_name = 'Joey'
assert user.valid?
end
Here is my user.rb file that validates the profile_name:
validates :profile_name,
presence: true,
uniqueness: true,
format: {
with: /^[a-ZA-Z0-9_-]+$/,
}
and here is the error i get in my terminal:
Rack::File headers parameter replaces cache_control after Rack 1.5.

4,494 PointsNick's answer is incomplete, the regex should have a 0-9 in it like so:
validates :profile_name, format: {
with: /\A[a-zA-Z0-9\-\_]+\Z/,
message: "must be formatted correctly."
}

Treehouse TeacherHi Prosper Hughie,
What Andre' said is correct, Jason provided a slightly different code example with the video.
validates :profile_name, format: {
with: /\A[a-zA-Z\-\_]+\Z/,
message: "must be formatted correctly."
}
I'm not sure if this will fix your issue, but Jason Seifer might be able to give you a better answer. :)
Jason Seifer
Treehouse Guest TeacherTry making the first "Z" lower case in the regular expression. That seems to be the issue here. Also, we fix it a little later in the videos :)

Treehouse Guest TeacherHashim Warren we don't have any regex only videos. Great idea, though!

26,671 Pointsif this is the reg expression from the video its wrong. Under the video he posted a reg slightly different reg expression that might solve your problem
