  • 请教关于 restful 的问题 at 2012年04月14日

    好的,感谢你的帮助,我再多研究一下!谢谢啦

  • 噢,我突然好像明白了,这个 Sample 里面用到了一个 Cucumber 黄瓜的东东。

  • 补充一下,还有一个文件是 signing_in.feature 这个.feature 的后缀之前没见过啊,里面的内容是

    Feature: Signing in
    
      Scenario: Unsuccessful signin
        Given a user visits the signin page
        When he submits invalid signin information
        Then he should see an error message
    
      Scenario: Successful signin
        Given a user visits the signin page
          And the user has an account
          And the user submits valid signin information
        Then he should see his profile page
          And he should see a signout link
    
    
    
  • OK,都是没有 reload 惹的祸呐!!!辛苦各位啦

  • 已经这样做了,还是不行。。。。

  • class User < ActiveRecord::Base attr_accessible :email, :unn

    has_many :microposts, :foreign_key => 'user_uid' end

  • 感觉这是个 BUG?无解了?

  • 还是没办法改过来

  • ActiveRecord::StatementInvalid: Mysql2::Error: Unknown column 'microposts.user_id' in 'where clause': SELECT microposts.* FROM microposts WHERE microposts.user_id = 1

  • @Ddl1st 我这样操作了,还是不行。

  • 外键错了?能详细说说吗?

  • 在我的 microposts 表里面,是没有 user_id 这个字段的,我是设置的 user_uid 这个字段

  • 重要的错误提示我觉得应该是这句

    first_user.microposts Micropost Load (0.3ms)ActiveRecord::StatementInvalid: Mysql2::Error: Unknown column SELECT microposts.* FROM microposts WHERE microposts.user_id = 1 'microposts.user_id'Mysql2::Error: Unknown column 'microposts.user_id' in 'where clause': SELECT microposts.* FROM microposts WHERE microposts.user_id = 1 in 'where clause': SELECT microposts.* FROM microposts WHERE microposts.user_id = 1

  • 检查了,那个没问题。

  • first_user.email(不是 first.user.email,笔误)

  • @Rei 类名打错了?没打错啊

    first.user.email

    是可以正常显示结果的

  • first_user.micropost.content NoMethodError: undefined method micropost' for #<User:0x00000101c38320> from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/activemodel-3.2.3/lib/active_model/attribute_methods.rb:407:inmethod_missing' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/activerecord-3.2.3/lib/active_record/attribute_methods.rb:148:in method_missing' from (irb):31 from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands/console.rb:47:instart' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands/console.rb:8:in start' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands.rb:41:in' from /Users/JasonJiang/ror/TestSQL/script/rails:6:in require' from /Users/JasonJiang/ror/TestSQL/script/rails:6:in' from -e:1:in load' from -e:1:in

  • 没有的,显示如下:

    irst_user.micropost.content NoMethodError: undefined method micropost' for #<User:0x00000101c38320> from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/activemodel-3.2.3/lib/active_model/attribute_methods.rb:407:inmethod_missing' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/activerecord-3.2.3/lib/active_record/attribute_methods.rb:148:in method_missing' from (irb):31 from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands/console.rb:47:instart' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands/console.rb:8:in start' from /Users/JasonJiang/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.2.3/lib/rails/commands.rb:41:in' from /Users/JasonJiang/ror/TestSQL/script/rails:6:in require' from /Users/JasonJiang/ror/TestSQL/script/rails:6:in' from -e:1:in load' from -e:1:in

  • 啊。已经创建了啊。

  • 找到原因了,需要在.bash_profile 里设置一下就行了。希望大家以后遇到这个问题,能轻松解决啊

  • @hujoy 精辟!
