pyenv在macOS上安装了python 3.7.0 。

sqlite3 已安装：

which sqlite3
/usr/bin/sqlite3

还尝试pysqlite3通过pip 安装：

pip install pysqlite3

但是在导入时找不到模块sqlite3：

In [1]: import sqlite3
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)

在Facebook页面上,我们可以点击"喜欢"按钮来查看页面.我们如何使用任何api或插件来实现其他网站？

使用 Rails 4.1.6 和 active_model_serializers 0.10.3

应用程序/序列化器/product_serializer.rb

class ProductSerializer < ActiveModel::Serializer
  attributes :id, :title, :price, :published
  has_one :user
end

应用程序/控制器/api/v1/products_controller.rb

class Api::V1::ProductsController < ApplicationController
  respond_to :json

  def index
    products = Product.search(params).page(params[:page]).per(params[:per_page])
    render json: products, meta: pagination(products, params[:per_page])
  end
end

当我检查响应正文时，它仅显示产品数据：
