Question

大家好，我有acvtive record rails 3.2和ruby 2.0

的问题

这里是我项目的示例代码

=============================================== =======================

test "to_csv_header should be available" do
    header_cells = CSV.parse(AccountAttribute.to_csv_header)[0]
    header_correct =
      ["#",
       _('AccountAttribute|Created at'),
       "#{_('AccountAttribute|Sex')} (#{_('description of AccountAttribute|Sex')})",
       _('AccountAttribute|Birthday')]
    assert_equal(header_correct, header_cells)
  end

  test "to_csv should be available" do
    aa = AccountAttribute.first
    assert_not_nil aa
    cells = CSV.parse(aa.to_csv)[0]
    assert_equal(AccountAttribute.csv_num_cols, cells.size)
  end

=============================================== =======================

当我在rails 3.0.2和ruby 1.9.3中运行测试时。测试成功通过，但是当我升级到rails 3.2和ruby 2.0时。它有如下错误：

=============================================== =======================

错误：test_to_csv_should_be_available（AccountAttributeTest）
ActiveRecord :: StatementInvalid：PG ::错误：错误：关系＆＃34; accountattributes＆＃34;不存在第5行：在哪里 a.attrelid =＆＃39;＆＃34; accountattributes＆＃34;＆＃39; :: regcl ... ^：选择a.attname，format_type（a.atttypid，a.atttypmod）， pg_get_expr（d.adbin，d.adrelid），a.attnotnull，a.atttypid，a.atttypmod 从pg_attribute到LEFT JOIN pg_attrdef d 在a.attrelid = d.adrelid和a.attnum = d.adnum 在哪里a.attrelid =＆＃39;＆＃34; accountattributes＆＃34;＆＃39; :: regclass 和a.attnum＆gt; 0而不是a.attisdropped ORDER BY a.attnum test / unit / account_attribute_test.rb：20：在`block in ＆＃39;

=============================================== =======================

对这些人有任何想法，如果你这样做，请告诉我。谢谢。 CMIIW
