Devise ::无法通过rake db：seed创建用户(失败confirm_instructi

def self.createadmin(
User.create(:email => "abc@gmail.com",:password => "123456e",:password_confirmation => "123456e",:terms_of_service => '1')
end

在rake db：seed中,我必须调用User.createadmin

但是,这失败了

ActionView::Template::Error: ActionView::Template::Error
    from /Users/bever/Projects/tr/app/views/devise/mailer/confirmation_instructions.html.erb:3:in `_app_views_devise_mailer_confirmation_instructions_html_erb___1974818942364630283_2154906860'

然后我在createadmin中更改了代码

begin
User.create(:email => "abc@gmail.com",:terms_of_service => '1')
rescue => e
User.create(:email => "abc@gmail.com",:terms_of_service => '1')
end

有用！任何线索为什么会发生这种情况？
