我有两个模型课，

class Designation < ActiveRecord::Base
  attr_accessible :name
  validates :name, presence: true, uniqueness: { case_sensitive: false }
  has_many :employee_details
  accepts_nested_attributes_for :employee_details
end

和

class EmployeeDetail < ActiveRecord::Base
  belongs_to :Designation
  attr_accessible :bloodGroup, :dob, :doc, :doj, :empId, :name, :panNo, :status, :Designation
end

我已经为 EmployeeDetail 生成了默认脚手架。当我尝试在指定文本框中创建和输入整数值时，来自 EmployeeDetail 页面，它给了我错误 ActiveRecord::AssociationTypeMismatch in EmployeeDetailsController#create Designation(#81846160) expected, got String(#75419260)。

谁能帮我解决这个问题？EmployeeDetailController#create:- def create @employee_detail = EmployeeDetail.new(params[:employee_detail])

respond_to do |format|
  if @employee_detail.save
    format.html { redirect_to @employee_detail, notice: 'Employee detail was successfully created.' }
    format.json { render json: @employee_detail, status: :created, location: @employee_detail }
  else
    format.html { render action: "new" }
    format.json { render json: @employee_detail.errors, status: :unprocessable_entity }
  end
end

当您关联任何模型时，您应该使用模型名称的小写版本。

改变：

belongs_to :Designation

至：

belongs_to :designation
