ruby-on-rails - 未定义的方法“columns_hash”

Question

我shoulda_matchers在我的specs. 对于这个测试

it { should validate_uniqueness_of(:name).scoped_to(:role_id) }

我收到此错误：

Expected errors to include "has already been taken" when name is set to "arbitrary_string", got errors: ["name is already taken (\"arbitrary_string\")"]

当我将测试更改为：

it { should validate_uniqueness_of(:name).scoped_to(:role_id).with_message('is already taken') }

我收到此错误：

 NoMethodError:
       undefined method `columns_hash' for Activity:Class

我的模型只有一个字段 -name

Answer 1

Mongoid模型没有columns_hash类方法并shoulda-matchers使用此方法。

中对应的方法mongoid是columns

我能够通过替换gemsshoulda和.shoulda-matchersmongoid-rspec
