测试开发进阶(三十四)

数据库模型图

创建app

根据上面的数据库设计，创建9个app

• configures

• debugtalks

• envs

• interfaces

• projects

• reports

• testsuits

• testcases

• user

完成注册

import sys
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'rest_framework',
    'corsheaders',
    'configures.apps.ConfiguresConfig',
    'debugtalks.apps.DebugtalksConfig',
    'envs.apps.EnvsConfig',
    'interfaces.apps.InterfacesConfig',
    'projects.apps.ProjectsConfig',
    'reports.apps.ReportsConfig',
    'testsuits.apps.TestsuitsConfig',
    'testcases.apps.TestcasesConfig',
    'user.apps.UserConfig',
]

抽象数据库基类

从数据库模型图可以看出，有很多部分都重复了

• create_time

• update_time

• is_delete

from django.db import models
class BaseModel(models.Model):
    """
    数据库表公共字段
    """
    create_time = models.DateTimeField(auto_now_add=True, verbose_name="创建时间", help_text="创建时间")
    update_time = models.DateTimeField(auto_now=True, verbose_name="更新时间", help_text="更新时间")
    is_delete = models.BooleanField(default=False, verbose_name="逻辑删除", help_text="逻辑删除")
    class Meta:
        # 为抽象模型类, 用于其他模型来继承，数据库迁移时不会创建BaseModel表
        abstract = True
        verbose_name = "公共字段表"
        db_table = 'BaseModel'

default=False默认情况下不删除

projects需求

• 删除项目时，只进行逻辑删除

• 获取项目列表信息时，要求能获取此项目下的「接口总数」，「用例总数」，「配置总数」，「套件总数」，同时输出创建时间，格式为2019-11-05 11:43:00

• 要求提供获取此项目下的所有项目名的接口

• 要求提供获取此项目下的所有接口信息的接口

序列化器
