我刚刚将我的应用程序升级到Rails 4，而且我的一些RSpec规格现在都失败了，都是以同样的方式。
SQL (82.3ms) INSERT INTO "profiles" ("career_goal", "created_at", "email", "encrypted_password", "first_name", "gpa", "grad_year", "hidden", "keywords", "kind", "last_name", "major_names", "middle_name", "minor_names", "phone", "id", "research_interest", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [["career_goal", ["Illum et sunt.", "Illo sapiente nesciunt reiciendis nulla fugit est autem."]], ["created_at", Sat, 21 Jun 2014 15:12:40 PDT -07:00], ["email", "madonna@huels.name"], ["encrypted_password", "$2a$10$y1zijhGouDy1OT4qHGnXR./FvXP9T7DHHvu4BofAt5ZBJrqjFisty"], ["first_name", "Jayde"], ["gpa", #<BigDecimal:e684850,'0.25E1',18(36)>], ["grad_year", 2013], ["hidden", false], ["keywords", "Daisha Ea placeat debitis repellendus autem ad voluptas. Illum et sunt. Illo sapiente nesciunt reiciendis nulla fugit est autem. "], ["kind", "student"], ["last_name", "Reilly"], ["major_names", "Anthropology"], ["middle_name", "Daisha"], ["minor_names", "Sociology"], ["phone", "724-953-4023 x4372"], ["id", "01234567"], ["research_interest", "Ea placeat debitis repellendus autem ad voluptas."], ["updated_at", Sat, 21 Jun 2014 15:12:40 PDT -07:00]]
TypeError: can't cast Array to text: INSERT INTO "profiles" ("career_goal", "created_at", "email", "encrypted_password", "first_name", "gpa", "grad_year", "hidden", "keywords", "kind", "last_name", "major_names", "middle_name", "minor_names", "phone", "id", "research_interest", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
看起来SQL调用现在在INSERT INTO "profiles" ("fields", etc) VALUES (?,?,?)的for中以某种方式格式错误任何关于VALUES部分为什么的见解？s将不胜感激。我检查了我的定义：配置文件，它似乎不像我在其他地方读过的Faker问题。 （我有Faker::Lorem.words(4).join('-')没有提供数组或任何内容。这是一个Active Record问题吗？还有其他地方我应该寻找错误或需要重新配置的东西吗？
答案 0 :(得分：0)
问号不是问题;他们是价值观的占位符。
这一部分值
["career_goal", ["Illum et sunt.", "Illo sapiente nesciunt reiciendis nulla fugit est autem."]]
表示career_goal设置为数组。将其更改为单个字符串（使用join或通过重写它，无论如何）。
