Question

I have a model called User. In the model I want to check if a value is true or false.
If the value is true then break all operations and redirect to a specific page.

How do I do that?

before_create :check_user

def check_user
    if User.find_by_email(self.email)
        redirect_to root_path
    end
end

You can’t and you never need to redirect form model.

You should do it in controller something like

before_filter :check_user
...
private
def check_user
  redirect_to root_path unless User.find_by_email(params[:user][:email])
end
