已经解决了:出现“ArgumentError in Issues#edit”问题,说第三行“<%= form_for issue do |f| %>”有问题,都是按照视频做的,不知道为何???
ArgumentError in Issues#edit
Showing /vagrant_data/meetup/app/views/issues/_form.html.erb where line #3 raised:
First argument in form cannot contain nil or be empty
Extracted source (around line #3):
<%= form_for issue do |f| %>
#解决方法
最后到code里复制了代码,又好了,可能是那个代码没打好,有可能是issues_controller.rb里的问题
