做web应用肯定少不了，用户的管理（增删改查）等操作
第一步：分析我们需要的字段，进行建模
models.py
----
class teuser(models.Model):
username = models.CharField(max_length=255)
password = models.CharField(max_length=255)
email = models.CharField(max_length=255)第二步：执行命令生成数据表
python manage.py makemigrations
python manage.py migrate
第三部：写代码
#导入模块
from django.contrib.auth.hashers import make_password, check_password #密码加密&解密
from django.views.decorators.csrf import csrf_exempt #跨域访问
from store.models import teuser #导入models
from django.http import HttpResponse
# 创建用户
@csrf_exempt
def create_user(request):
#get请求就返回创建用户页面
if request.method == 'GET':
return render(request, 'createuser.html')
#post请求就执行创建操作
elif request.method == 'POST':
try:
username = request.POST.get('createUsername')
password = request.POST.get('password')
email = request.POST.get('email')
# 明文密码经过加密处理
passwords = make_password(password,None,'pbkdf2_sha256')
print('getpassword is value:',passwords)
createResult = teuser.objects.create(username = username,password = passwords,email = email)
#createResult. set_password(passwords)
createResult.save()
return HttpResponse('1')
except:
return HttpResponse('-1')
# 删除用户
@csrf_exempt
def delete_user(request,id):
if request.method == 'GET':
try:
result = teuser.objects.filter(id=id)
result.delete()
return HttpResponse('success')
except:
return HttpResponse('fail')
#获取修改用户的页面
def editUser(request,id):
if request.method == 'GET':
#result = User.objects.filter(id)
result = teuser.objects.filter(id=id)
#print("需要修改的用户名为：".format(result))
template = get_template('updateuser.html')
html = template.render({'content': result})
return HttpResponse(html)
# 修改密码
###思路：获取前台页面的数据，把获取到的password跟数据库查询值指定的password进行比对，是true就执行修改操作，是false就弹框###
@csrf_exempt
def change_password(request):
if request.method == 'POST':
try:
username = request.POST.get('username')
oldPassword = request.POST.get('oldPassword')
newPassword = request.POST.get('newPassword')
name = teuser.objects.filter(username=username)
for item in name:
getpwd = item.password
#判断获取到的密码跟数据库的密码是否一致
ck = check_password(oldPassword, getpwd)
if ck:
cknewpassword = make_password(newPassword, None, 'pbkdf2_sha256')
#新密码进行加密并修改保存在数据库
item.password = cknewpassword
item.save()
return HttpResponse('1')
else:
return HttpResponse('-1')
except Exception as e:
print(e)
return HttpResponse('-1')
#用户列表
def listUser(request):
#查询用户所有的数据
result = teuser.objects.all()
template = get_template('list.html')
html = template.render({'content':result})
return HttpResponse(html)
urls.py
url(r'^createUser/$',views.create_user,name='createUser'),
#(.+)指传参数
url(r'^deleteUser/(.+)/$',views.delete_user,name='deleteUser'),
url(r'^changePassword/$',views.change_password,name='changePassword'),
url(r'^editUser/(.+)/$',views.editUser,name='editUser'),
url(r'^listUser/$',views.listUser,name='listUser'),第四步：页面html代码
list.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<a href="/createUser">创建用户</a>
<table border="1" text-align="center">
<thead>
<tr>
<th>编号</th>
<th>用户名</th>
<th>密码</th>
<th>邮箱</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{# 这里是模板语言，for循环，最后需要 endfor#}
{% for foo in content %}
<tr>
<td>{{ foo.id }}</td>
<td>{{ foo.username }}</td>
<td>{{ foo.password }}</td>
<td>{{ foo.email }}</td>
<td><a href="{% url 'editUser' foo.id%}">修改</a></td>

{% endfor %}
</tbody>
</table>
