数据库 postgresql

我有以下迁移：

class AlterBirthdayInUsers < ActiveRecord::Migration[5.0]
  def change
    change_column :users, :birthday, 'date USING CAST(birthday AS date)', default: Date.today
  end
end

迁移开始出错：

rake stdout: == 20170201162913 AlterBirthdayInUsers: migrating =======================
-- change_column(:users, :birthday, "date USING CAST(birthday AS date)", {:default=>Sat, 18 Feb 2017})
rake stderr: rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

PG::InvalidDatetimeFormat: ERROR:  invalid input syntax for type date: ""
: ALTER TABLE "users" ALTER COLUMN "birthday" TYPE date USING CAST(birthday AS date)

类型日期的迁移字段中 postgrees …

我在Rails 5 beta 3中遇到了gem acts-as-taggable-on的问题.

project.rb:

class Project < ActiveRecord::Base       
  acts_as_taggable
  acts_as_taggable_on :skills
end

的routes.rb

get 'tags/:skill', to: 'projects#index', as: :skill

projects_controller.rb:

class ProjectsController < ApplicationController
  def index
    if params[:category] && Category.exists?(params[:category])
      @category = Category.find(params[:category])
      @projects = @category.projects.order("projects.created_at DESC")    
    elsif params[:skill]
      @projects = Project.tagged_with(params[:skill])
    else  
      @projects = Project.all
    end

    @categories = Category.all
  end
end

在线@projects = Project.tagged_with(params[:skill])我得到以下错误:

ArgumentError:来自/usr/local/rvm/gems/ruby-2.3.0/gems/activerecord-5.0.0.beta3/lib/active_record/sanitization.rb:8:in的参数数量错误(给定2,预期为1) `的sanitize"

我有导入导出服务。

在方法ConfigureServices 的StartUp 类中，我将其用作

services.AddImportExportService(Configuration.GetConnectionString("DefaultConnection"));

扩展方法AddImportExportService：

public static class IServiceCollectionExtension
    {
        public static IServiceCollection AddImportExportService(this IServiceCollection services, 
            string connString,
            ILogger<ImportExportService> logger
            )
        {
            services.AddTransient<IImportExportService, ImportExportService>(provider => new ImportExportService(connString));
            return services;
        }
    }

ExportImportService 使用日志记录。我尝试将日志记录作为构造函数中的参数注入ILoger<ImportExportService> logger，但构造函数仅包含一个参数，并且扩展方法 AddImportExportService 出现错误。

如何在ExportImportService中注入Logging？谢谢
