Rails 5：弃用警告：您正在将 ActiveRecord::Base 的实例传递给“存在？”。 ..我不知道
Rails 5: DEPRECATION WARNING: You are passing an instance of ActiveRecord::Base to `exists?`. ..I have no idea
好的....我有一个模式中的表单要提交。我不明白我收到的警告/错误阻止 POST 发生。我错过了什么？
这是让我抓狂的剥夺警告
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)
请注意没有“存在”？在第 35 行（见下文）。
这是第 35 行标记为
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|

format.html { redirect_to @assignment, notice: "Assignment was successfully created." }
format.json { render :show, status: :created, location: @assignment }

这东西要我干什么？我错过了什么？
如果结果是没有数据被保存到数据库中，而是有一个ROLLBACK。然后从我的角度来看，有些东西坏了，这是一个“错误”。或者更确切地说，“错误”已经发生，因为结果不是所期望的。

这告诉您您的联系人已经存在，因此如果您希望该代码起作用，请创建一个尚不存在的联系人，或者更改执行此检查的模型代码或数据库模式（如果您有）一个独特的 属性 集，您的代码中没有错误，警告只是弃用警告而不是错误。
您似乎正在访问一条已经存在的记录，所以您可能想要更新而不是创建？这可能是逻辑错误而不是编码错误，但只有您知道您要做什么
