[英]Rails - Test validation of enum fields
I'm using Rails 4 enums and I want to properly test them, so I set these tests up for my enum fields:我正在使用 Rails 4 枚举,我想正确测试它们,所以我为我的枚举字段设置了这些测试:
it { should validate_inclusion_of(:category).in_array(%w[sale sale_with_tax fees lease tax_free other payroll]) }
it { should validate_inclusion_of(:type).in_array(%w[receivable payable]) }
And this is the model they're validating:这是他们正在验证的模型:
class Invoice < ActiveRecord::Base
belongs_to :user
enum category: [:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll]
enum type: [:receivable, :payable]
validates :user, presence: true
validates :issue_date, presence: true
validates :series, presence: true
validates :folio, presence: true
validates :issuing_location, presence: true
validates :payment_method, presence: true
validates :last_digits, presence: true
validates :credit_note, presence: true
validates :total, presence: true
validates :subtotal, presence: true
validates :category, presence: true
validates_inclusion_of :category, in: Invoice.categories.keys
validates :type, presence: true
validates_inclusion_of :type, in: Invoice.types.keys
end
But when I run the tests I get:但是当我运行测试时,我得到:
1) Invoice should ensure inclusion of type in [0, 1]
Failure/Error: it { should validate_inclusion_of(:type).in_array([0,1]) }
ArgumentError:
'123456789' is not a valid type
# ./spec/models/invoice_spec.rb:20:in `block (2 levels) in <top (required)>'
2) Invoice should ensure inclusion of category in [0, 1, 2, 3, 4, 5, 6]
Failure/Error: it { should validate_inclusion_of(:category).in_array([0,1,2,3,4,5,6]) }
ArgumentError:
'123456789' is not a valid category
# ./spec/models/invoice_spec.rb:19:in `block (2 levels) in <top (required)>'
I've also tried with string values in the test arrays, but I get the same error and I really don't understand it.我也试过在测试数组中使用字符串值,但我得到了同样的错误,我真的不明白。
Using Shoulda matchers we can use the following to test the enum使用 Shoulda 匹配器,我们可以使用以下内容来测试枚举
it { should define_enum_for(:type).with([:receivable, :payable]) }
it { should define_enum_for(:category).
with(:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll) }
Try this:尝试这个:
it { should validate_inclusion_of(:category).in_array(%w[sale sale_with_tax fees lease tax_free other payroll].map(&:to_sym)) }
Additionally, for code-cleanup, try putting the valid categories/types in a corresponding constant.此外,对于代码清理,请尝试将有效类别/类型放在相应的常量中。 Example:例子:
class Invoice < ActiveRecord::Base
INVOICE_CATEGORIES = [:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll]
enum category: INVOICE_CATEGORIES
end
Your migration could be the issue, it should look something like:您的迁移可能是问题所在,它应该类似于:
t.integer :type, default: 1
You may also consider testing this another way.您也可以考虑以另一种方式进行测试。
Maybe more like:也许更像:
it "validates the category" do
expect(invoice with category fee).to be_valid
end
只需使用shoulda 匹配器:
it { should define_enum_for(:type).with_values([:receivable, :payable]) }
it { should define_enum_for(:category).with_values(:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll)}
Use shoulda matchers along with check for column_type.使用 shoulda 匹配器并检查 column_type。
it do
should define_enum_for(:type).
with_values(:receivable, :payable).
backed_by_column_of_type(:integer)
end
it do
should define_enum_for(:category).
with_values(:sale, :sale_with_tax, :fees, :lease, :tax_free, :other, :payroll).
backed_by_column_of_type(:integer)
end
You have this string in your validations:您的验证中有此字符串:
validates_inclusion_of :category, in: Invoice.categories.keys
in case of enum Invoice.categories.keys #=> ["sale", "sale_with_tax", "fees", "lease", "tax_free", "other", "payroll"]如果是枚举 Invoice.categories.keys #=> ["sale", "sale_with_tax", "fees", "lease", "tax_free", "other", "payroll"]
You should update your object data with one of names of your enum.您应该使用枚举名称之一更新对象数据。
