快速构建 RESTful API

Project description

Dseagull

快速构建 RESTful API


INSTALLED_APPS

添加 dseagull 到 INSTALLED_APPS 中, 注意必须要放在 rest_framework 前面

INSTALLED_APPS = [
    ...
    'dseagull',
    'rest_framework',
]

MIDDLEWARE

添加 dseagull.logger.LoggerMiddleware 到 MIDDLEWARE 中, 用于收集日志的字段

MIDDLEWARE = [
    'dseagull.logger.LoggerMiddleware',
    ...
]

REST_FRAMEWORK

不需要配置 REST_FRAMEWORK, 默认配置如下:

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'dseagull.pagination.PageNumberPagination',
    'PAGE_SIZE': 10,
    'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema',
    'DEFAULT_FILTER_BACKENDS': [
        'django_filters.rest_framework.DjangoFilterBackend',
        'rest_framework.filters.SearchFilter',
        'rest_framework.filters.OrderingFilter',
    ],
    
}

models.BaseModel

提供基础模型, 添加了 created_at, updated_at

from django.db import models


class BaseModel(models.Model):
    class Meta:
        abstract = True

    created_at = models.DateTimeField(
        auto_now_add=True, verbose_name='创建时间', db_index=True,
    )
    updated_at = models.DateTimeField(
        auto_now=True, verbose_name='更新时间', db_index=True,
    )

serializers.Field

支持 required=True 时提示带上字段的 help_text 信息

from rest_framework.serializers import Serializer
class ExampleSerializer(Serializer):
    name = field(help_text='姓名')
ExampleSerializer(data={}).is_valid()

原本提示:这个字段是必填项。

现提示:姓名:这个字段是必填项。


支持 required=True, null=False 时提示带上字段的 help_text 信息

from rest_framework.serializers import Serializer
class ExampleSerializer(Serializer):
    name = field(help_text='姓名')
ExampleSerializer(data={'name': None}).is_valid()

原本提示:This field may not be null. 现提示:姓名:不能为空。


支持 required=True, null=False 时提示带上字段的 help_text 信息

from rest_framework.serializers import Serializer
class ExampleSerializer(Serializer):
    name = field(help_text='姓名')
ExampleSerializer(data={'name': ''}).is_valid()

原本提示:This field may not be blank. 现提示:姓名:不能为空白。


Filters

支持时间区间的查询

from dseagull.filters import BaseFilterSet
class PersonFilter(BaseFilterSet):
    last_name = filters.CharFilter()
    created_at = filters.CharFilter(method='filter_datetime', )

    class Meta:
        model = Person
        fields = ('id',)

在查询时, 参数输入 /?created_at=1738771200,1738771201 即可过滤出对应的数据


Commands

startmodel

python manage.py startmodel -n Apple

执行上面的命令, 可以自动创建和修改标准化的 model, serializer, viewset, routers


JWT

简化对称加密型的 JWT 编码和解码的过程, 需要配置 JWT_KEY 和 JWT_EXP,

from dseagull.djwt import JWTHS256
token = JWTHS256().encode({'username': 'admin'})
payload = JWTHS256().decode(token)
