我已经使用Ubuntu 16.04 amd64服务器上https://gorails.com/setup/ubuntu/16.04的说明安装了Rails。我使用'rbenv'而不是任何其他选项。
我创建了一个名为'testapp'的新应用程序。
然后我执行了:
$ rails generate scaffold Test name:string age:integer
然后,我执行了:
$ bin/rails generate integration_test tests_post
我修改了test / integration / tests_post_test.rb,内容如下:
require 'test_helper'
class TestsPostTest < ActionDispatch::IntegrationTest
test "can create an item" do
get "/tests/new"
assert_response :success
post "/tests",
params: { test: { name: 'Micky Mouse', age: 120 } }
assert_response :redirect
follow_redirect!
assert_response :success
end
end
然后我执行了:
rake test
这给了我以下错误:
Run options: --seed 24994
# Running:

然而,相关的日志记录显示以下内容:

在开发和生产中,只有在测试中才会出现错误。我一直在查看我在其他项目中在网上看过的例子,但我没有看到我在这里特别做了什么。我创建了这些具体步骤,以尽可能简单地显示问题。任何想法如何让这个正常工作?这个版本的rake(11.3.0)中是否有错误?
答案 0 :(得分:2)
您可能正在使用Rails 4(考虑到您正在关注的安装教程)。对于Rails 4,在发布集成测试时,您不需要包装params。改变这一行:
createIndex
到
func createIndex<Key, Element>(elms:[Element], extractKey:(Element) -> Key) -> [Key:Element] where Key : Hashable {
var dict = [Key:Element]()
for elm in elms {
dict[extractKey(elm)] = elm
}
return dict
}
你会没事的。
