Question

我在ActiveAdmin控制器内部工作。我正在尝试传递allowed_params以及当前日期和当前登录的用户。但是，每当我提交时，我都会收到Unknown attribute 'utf8' for Permit错误。

系统管理员/ permit.rb

form do |f|
    f.inputs do
        f.input :vehicle, :collection => Vehicle.all.map{ |vehicle| [vehicle.license_number]}
        f.input :permit_id
        f.input :date_issued, as: :date_picker
        f.input :issued_by
    end
    f.actions
end

controller do
    def new
        @permit = Permit.new
        @vehicle = @permit.build_vehicle 
    end 

    def create
         #@permit = Permit.new
         vehicle = Vehicle.find_by(permitted_params[:vehicle])
         @permit = current_user.permit.build(permitted_params.merge(date_entered: Date.today, 
            entered_by: current_admin_user.email))
         @permit.update(vehicle: vehicle)
         super
    end

    def permittted_params
        params.require(:permit).permit(:permit_id, :date_issued, :issued_by, :date_entered, :entered_by, vehicle_attributes: [:license_number])
    end

    def set_permit
        @permit = Permit.find(params[:id])
    end
end

有人知道我为什么会收到这个错误吗？我在正常的rails应用程序中没有收到此错误，并且它运行的代码几乎相同。感谢

当我使用邮递员时，我遇到了这个错误。设置标题：enctype multipart/form-data; charset=utf-8
