目录
5、添加用户user_model_form_add.html--- 新方法（ModelForm）
10、删除用户在views.py新增user_delete方法
使用pycharm创建django项目
1、删除settings配置
删除下图[]内容
2、删除templates文件夹
三、创建app（应用）与注册应用
1、创建app
# XXX项目名
python manage.py startapp xxx2、注册app
修改settings如下图，红色方框是创建的app名
1、安装pymysql
pip install pymysql
2、配置在项目同名包下的_init_.py里面添加
import pymysql
pymysql.install_as_MySQLdb()3、修改settings.py
,注释db.sqlite3的配置新增下图
# DATABASES = {
# 'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': BASE_DIR / 'db.sqlite3',
# }
# }
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # 数据库的类型
'NAME': 'texx', # 所使用的的数据库的名字
'USER': 'root', # 数据库服务器的用户
'PASSWORD': 'xxxx', # 密码
'HOST': '127.0.0.1', # 主机
'PORT': '3306', # 端口
}
}1、在models.py创建类
from django.db import models
# Create your models here.
class Department(models.Model):
"""部门表"""
name = models.CharField(verbose_name='部门名称', max_length=20)
class UserInfo(models.Model):
"""员工表"""
name = models.CharField(verbose_name='姓名', max_length=20)
password = models.CharField(verbose_name='密码', max_length=64)
age = models.IntegerField(verbose_name='年龄')
gender_choices = ((1, '男'), (2, '女'))
gender = models.SmallIntegerField(verbose_name='性别',choices=gender_choices)
account = models.DecimalField(verbose_name='账户余额', max_digits=10, decimal_places=2,default=0)
create_time = models.DateTimeField(verbose_name='入职时间')
# depart会自动生成字段为depart_id
# 级联删除 on_delete=models.CASCADE
# 置空 on_delete=models.SET_NULL 但是必须和null=True, blank=True配合使用，因为你得支持为null
depart = models.ForeignKey(to='Department', to_field='id', on_delete=models.CASCADE)
2、创建一个mysql数据库（略）
3、django命令生成库表
python manage.py makemigrations
python manage.py migrate另一个方法：按下图操作之后就可省略上图 python manage.py 命令直接输入后面的即可
1、创建下图目录
2、将下载的bootstrap-3.4.1复制到plugins
3、将下载的jquery-3.6.3.min.js复制到js
4、在app应用下创建templates文件夹
1）设置部门列表路由
from django.contrib import admin
from django.urls import path
from TestManagementSystem import views
urlpatterns = [
# path('admin/', admin.site.urls),
path('depart/list/', views.depart_list),
]
2）创建部门列表views.py视图
from django.shortcuts import render
from TestManagementSystem import models
# Create your views here.
def depart_list(request):
"""部门列表"""
# 查询所有部门
depart_set = models.Department.objects.all()
print(depart_set)
return render(request, 'depart_list.html', {"depart_set": depart_set})
3）创建部门列表html页面
在templates下创建depart_list.html
先引入样式、js等

如何在buildr项目中使用Ruby？我在很多不同的项目中使用过Ruby、JRuby、Java和Clojure。我目前正在使用我的标准Ruby开发一个模拟应用程序，我想尝试使用Clojure后端(我确实喜欢功能代码)以及JRubygui和测试套件。我还可以看到在未来的不同项目中使用Scala作为后端。我想我要为我的项目尝试一下buildr(http://buildr.apache.org/)，但我注意到buildr似乎没有设置为在项目中使用JRuby代码本身!这看起来有点傻，因为该工具旨在统一通用的JVM语言并且是在ruby中构建的。除了将输出的jar包含在一个独特的、仅限ruby
我有一个ModularSinatra应用程序，我正在尝试将Bootstrap添加到应用程序中。get'/bootstrap/application.css'doless:"bootstrap/bootstrap"end我在views/bootstrap中有所有less文件，包括bootstrap.less。我收到这个错误:Less::ParseErrorat/bootstrap/application.css'reset.less'wasn'tfound.Bootstrap.less的第一行是://CSSReset@import"reset.less";我尝试了所有不同的路径格式，但它
我在我的Rails项目中使用Pow和powifygem。现在我尝试升级我的ruby版本(从1.9.3到2.0.0，我使用RVM)当我切换ruby版本、安装所有gem依赖项时，我通过运行railss并访问localhost:3000确保该应用程序正常运行以前，我通过使用pow访问http://my_app.dev来浏览我的应用程序。升级后，由于错误Bundler::RubyVersionMismatch:YourRubyversionis1.9.3,butyourGemfilespecified2.0.0，此url不起作用我尝试过的:重新创建pow应用程序重启pow服务器更新战俘
我已经像这样安装了一个新的Rails项目:$railsnewsite它执行并到达:bundleinstall但是当它似乎尝试安装依赖项时我得到了这个错误Gem::Ext::BuildError:ERROR:Failedtobuildgemnativeextension./System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/rubyextconf.rbcheckingforlibkern/OSAtomic.h...yescreatingMakefilemake"DESTDIR="cleanmake"DESTDIR="
我有一个用户工厂。我希望默认情况下确认用户。但是鉴于unconfirmed特征，我不希望它们被确认。虽然我有一个基于实现细节而不是抽象的工作实现，但我想知道如何正确地做到这一点。factory:userdoafter(:create)do|user,evaluator|#unwantedimplementationdetailshereunlessFactoryGirl.factories[:user].defined_traits.map(&:name).include?(:unconfirmed)user.confirm!endendtrait:unconfirmeddoenden
假设我有这个范围:("aaaaa".."zzzzz")如何在不事先/每次生成整个项目的情况下从范围中获取第N个项目？ 最佳答案 一种快速简便的方法:("aaaaa".."zzzzz").first(42).last#==>"aaabp"如果出于某种原因你不得不一遍又一遍地这样做，或者如果你需要避免为前N个元素构建中间数组，你可以这样写:moduleEnumerabledefskip(n)returnto_enum:skip,nunlessblock_given?each_with_indexdo|item,index|yieldit

MIMO技术的优缺点优点通过下面三个增益来总体概括：阵列增益。阵列增益是指由于接收机通过对接收信号的相干合并而活得的平均SNR的提高。在发射机不知道信道信息的情况下，MIMO系统可以获得的阵列增益与接收天线数成正比复用增益。在采用空间复用方案的MIMO系统中，可以获得复用增益，即信道容量成倍增加。信道容量的增加与min(Nt,Nr)成正比分集增益。在采用空间分集方案的MIMO系统中，可以获得分集增益，即可靠性性能的改善。分集增益用独立衰落支路数来描述，即分集指数。在使用了空时编码的MIMO系统中，由于接收天线或发射天线之间的间距较远，可认为它们各自的大尺度衰落是相互独立的，因此分布式MIMO
