RestfulAPI 解析

实现一款 no-sql 风格的参数解析框架rest-query，(like: /?select=id,name,author{id,name,school{*}})&id=gte.20&author.name=wwxiong&order=id.desc)。

目前实现了Django ORM和Peewee ORM

Django DEMO

定义模型

class Author(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) age = models.IntegerField() class Book(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) author = models.ForeignKey(Author) 

定义试图

from django.views.generic import ListView from django.views.generic.detail import DetailView from django_rest_query import RestQueryDetailViewMixin, RestQueryListViewMixin from .models import Author, Book class BookDetail(RestQueryDetailViewMixin, DetailView): model = Book class BookList(RestQueryListViewMixin, ListView): model = Book class AuthorDetail(RestQueryDetailViewMixin, DetailView): model = Author class AuthorList(RestQueryListViewMixin, ListView): model = Author 

这样我们就实现了Author和Book的查询 API 了。

API

查询姓名为dracarysX的作者,并只返回id, name:

curl http://localhost/authors?select=id,name 

查询书籍id大于 100，且作者姓名在['x', 'y', 'z']中，并返回书籍的id, name和作者的id, name,并按照书籍id倒序排序。

curl http://localhost/books?select=id,name,author{id,name}&id=gt.100&author.name=in.x,y,z&order=id.desc 

返回数据：

{ "count": 2, "object_list": [ { "id": 2, "name": "Javascript", "author": { "name": "x", "id": 2 } }, { "id": 1, "name": "Python", "author": { "name": "y", "id": 1 } } ], "is_paginated": false, "page": 1 }

PS

目前仅仅实现了 Django orm 和 Peewee 的解析。感兴趣的同学可以多多提意见和 issue，谢谢。
