好的....我有一個模態形式的表單，我正在嘗試提交。我不明白我收到的警告/錯誤是阻止 POST 發生。我錯過了什么？
這是讓我抓狂的降價警告
DEPRECATION WARNING: You are passing an instance of ActiveRecord::Base to `exists?`. Please pass the id of the object by calling `.id`. (called from block in create at /home/fonso/back-experiment/app/controllers/assignments_controller.rb:35)
請注意，沒有“存在？” 在第 35 行（見下文）。這是第 35 行標記的控制器操作
# POST /assignments or /assignments.json
def create
@assignment = Assignment.new(assignment_params)
# error wants contact.id not contact_id ???
respond_to do |format|
if @assignment.save #<-------------------LINE 35
format.html { redirect_to @assignment, notice: "Assignment was successfully created." }
format.json { render :show, status: :created, location: @assignment }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: @assignment.errors, status: :unprocessable_entity }
end
end
end
如果我用 Pry 停止它以查看物件通過我看到... Pry 控制臺輸出

這東西要我干嘛？我錯過了什么？
如果結果是沒有資料保存到資料庫，而是有一個 ROLLBACK。然后從我的角度來看，有些東西壞了，這是一個“錯誤”。或者更確切地說，發生了“錯誤”，因為結果不是所希望的。

這告訴您您的聯系人已經存在，因此如果您希望該代碼作業，則創建一個尚不存在的聯系人，或者更改執行此檢查的模型代碼或資料庫架構（如果您有唯一的屬性集），您的代碼中沒有錯誤，警告只是棄用警告而不是錯誤。您似乎正在訪問一個已經存在的記錄，所以您可能想要更新而不是創建？這可能是邏輯錯誤而不是編碼錯誤，但只有您知道您要做什么
