我已經在Ubuntu 16.04 amd64服務器上使用https://gorails.com/setup/ubuntu/16.04的指示安裝了Rails。我使用'rbenv'而不是其他任何選項。集成測試時,出現ActionController :: ParameterMissing,儘管日誌相反
我創建了一個名爲'testapp'的新應用程序。
我然後執行:
$ rails generate scaffold Test name:string age:integer
然後,我執行:
$ bin/rails generate integration_test tests_post
我修改測試/集成/ tests_post_test.rb讀取如下:
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
然後我執行了:
rake test
這給了我下面的錯誤:
Run options: --seed 24994

在研發和生產,這給沒有錯誤,只是在測試。我一直在尋找我在其他項目中在線看過的例子,但我沒有看到我在這裏做了任何特別的事情。我創建了這些具體步驟,以儘可能簡單地顯示問題。任何想法如何讓這個工作正常?這個版本的rake(11.3.0)中是否有bug?
你的'TestController'中有什麼,特別是72行? –
params.require(:test).permit(:name,:age),但這不是這個問題的本質。亞歷山大·安吉利姆(Alexandre Angelim)擁有它......只是改變了我在測試中指定參數的方式。 –
你應該學會如何調試這些問題,而不是記住像這樣的某些解決方案......你可以簡單地在該行上面放置一個'binding.pry',並檢查'params'的當前值 - 解決方案相當明顯。 –
