Heroku上的未定义rails方法

Question

I just pushed some changes heroku and now my app is broke, even though it runs find in dev. Here is what 'heroku logs' is saying...

2013-11-07T18:58:47.712744+00:00 app[web.1]: ActionView::Template::Error (undefined method `user_type' for #<User:0x007f1f2ca092e8>):

2013-11-07T18:58:47.712744+00:00 app[web.1]:     29: <% end %>
2013-11-07T18:58:47.712897+00:00 app[web.1]:   app/views/users/new.html.erb:2:in `_app_views_users_new_html_erb___2270355414211974343_69885950076300'

Looks like it does not like <%= f.select :user_type, options_for_select(['Bar', 'Brewery', 'Restaurant', 'Hotel'], @user.user_type) %>
Any ideas?

运行应用程序的所有迁移，然后使用heroku restart启动应用程序。

Answer 2

Ended up being the version of Ruby that I was using. I did not specify the ruby version in my Gemfile. I am using 1.9.3 in dev, but Heroku defaults to 2.0. I added the line...

ruby '1.9.3'

to the bottom of my Gemfile and I was good to hook.
