stackoverflow の最初の投稿です。noob のようなものについては事前にお詫びします。

機能テストの 1 つでエラーが発生しましたが、何時間も経った後、エラーをパスする方法がわかりません。

要するに、invoice_schedulewhich has_many invoice_milestones. 次に、invoice_milestones属性estimate_percentage(整数) を持ちます。私のモデルには、すべての合計が100 でなければならないmodels/invoice_schedule.rbという検証があります。estimate_percentages

create アクションの機能テストはinvoice_schedule毎回失敗します。以下の現在のコードでは、代わりにエラーが発生しています。渡したパラメーターでエラーが発生する方法がわかりません。

ということも記しておきますestimate has_one :invoice_schedule

どんな助けや提案も大歓迎です:)

models/invoice_schedule.rb:

class InvoiceSchedule < ActiveRecord::Base
    belongs_to :estimate
    has_many :invoice_milestones, :dependent => :destroy

    accepts_nested_attributes_for :invoice_milestones, :allow_destroy => true

    validate :total_must_equal_one_hundred_percent

    def total_must_equal_one_hundred_percent
        if total_percent != 100
            errors.add(:invoice_milestones, "Total must equal 100%")
        end
    end

    def total_percent
        invoice_milestones.to_a.sum { |item| item.estimate_percentage || 0 }
    end
end

models/invoice_milestone.rb:

class InvoiceMilestone < ActiveRecord::Base
    belongs_to :invoice_schedule
    belongs_to :invoice

    validates :estimate_percentage, :numericality => {:only_integer => true, :greater_than_or_equal_to => 0, :less_than_or_equal_to => 100}
end

        format.html { redirect_to invoice_schedule_path(@invoice_schedule), :flash => {:notice => 'Invoice schedule was successfully created.', :status => 'success'} }

機能テストで新しく作成されたinvoice_scheduleにinvoice_milestoneを追加するために、他にもいくつかの方法を試しましたが、うまくいかなかったようです。accept_nested_attributes_for が追加されている場合、上記のルーティング エラーが発生するのはなぜですか?

これには 2 つの部分があります。まず、ルーティング側を正しくする必要があります。見積書内に請求書スケジュールをネストしたため、estimate_id( 内ではなく) トップレベルでを指定する必要がありますparams[:invoice_schedules]。つまり、

post :create, :estimate_id => @data_estimate.id, :invoice_schedule => {...}

次に、コントローラーが次の行に沿って何かを行うことが期待されます

estimate = Estimate.find(params[:estimate_id])
@invoice_schedule = estimate.invoice_schedules.build params[:invoice_schedule]

2 番目の部分は、ネストされた属性を処理することです。Rails が期待するものと一致する params ハッシュを提供する必要があります。その最初の部分は、ハッシュのキーが:invoice_milestones_attributes. これは であるためhas_many、対応する値はハッシュの配列、またはハッシュのハッシュである必要があります (キーは無視されます - これは主に、Rails のパラメーター受け渡しにおける配列とハッシュ間の相互作用のために存在します)。

post :create, :estimate_id => @data_estimate.id, 
              :invoice_schedule => {
                :invoice_milestones_attributes => [
                  {:estimate_percentage => 100}
                ]
              }
