权限分配之用户管理
作者：互联网
用户管理示例图：
第一步：路由的创建
rbac/urls.py
from django.urls import re_path
from rbac.views import role
from rbac.views import user
urlpatterns = [
# 角色管理
re_path(r'^role/list/$', role.role_list, name="role_list"),
re_path(r'^role/add/$', role.role_add, name="role_add"),
re_path(r'^role/edit/(?P<pk>\d+)/$', role.role_edit, name="role_edit"),
re_path(r'^role/del/(?P<pk>\d+)/$', role.role_del, name="role_del"),
# 用户管理
re_path(r'^user/list/$', user.user_list, name="user_list"),
re_path(r'^user/add/$', user.user_add, name="user_add"),
re_path(r'^user/edit/(?P<pk>\d+)/$', user.user_edit, name="user_edit"),
re_path(r'^user/del/(?P<pk>\d+)/$', user.user_del, name="user_del"),
re_path(r'^user/reset/password/(?P<pk>\d+)/$', user.user_reset_pwd, name="user_reset_pwd"),
]
第二步：ModelForm的书写
rbac/forms/user.py
from django import forms
from rbac import models
from django.core.exceptions import ValidationError
class UserModelForm(forms.ModelForm):
"""添加用户"""
confirm_password = forms.CharField(
label="确认密码",
) # model中没有的字段，可自行添加一个该字段
class Meta:
model = models.Userinfo # 关联的表
fields = ["name", "email", "password", "confirm_password"] # 字段
# 错误提示改为中文的第一种方法
# error_messages = {
# "name": {"required": "用户名不能为空"},
# "email": {"required": "邮箱不能为空"},
# "password": {"required": "密码不能为空"},
# "confirm_password": {"required": "确认密码不能为空"}, # 无效
# }
# 错误提示改为中文的第二种方法(在settings.py中把LANGUAGE_CODE进行修改)
# LANGUAGE_CODE = 'zh-hans'
def __init__(self, *args, **kwargs):
"""为所有字段添加样式"""
super(UserModelForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
# name就是上面fields中的字段
field.widget.attrs["class"] = "form-control"
def clean_confirm_password(self):
"""局部钩子函数，校验两次密码是否一致"""
password = self.cleaned_data.get("password")
confirm_password = self.cleaned_data.get("confirm_password")
if password != confirm_password:
raise ValidationError("两次密码输入不一致...")
return confirm_password
class UpdateUserModelForm(forms.ModelForm):
"""编辑用户"""
class Meta:
model = models.Userinfo
fields = ["name", "email"]
def __init__(self, *args, **kwargs):
super(UpdateUserModelForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
field.widget.attrs["class"] = "form-control"
class ResetPasswordUserModelForm(forms.ModelForm):
"""重置密码"""
confirm_password = forms.CharField(
label="确认密码",
)
class Meta:
model = models.Userinfo
fields = ["password", "confirm_password"]
def __init__(self, *args, **kwargs):
super(ResetPasswordUserModelForm, self).__init__(*args, **kwargs)
for name, field in self.fields.items():
field.widget.attrs["class"] = "form-control"
def clean_confirm_password(self):
password = self.cleaned_data.get("password")
confirm_password = self.cleaned_data.get("confirm_password")
if password != confirm_password:
raise ValidationError("两次密码输入不一致...")
return confirm_password
第三步：视图函数的书写
rbac/views/user.py
"""角色管理"""
from rbac import models
from django.shortcuts import render, redirect, HttpResponse
from django.urls import reverse
from rbac.forms.user import UserModelForm, UpdateUserModelForm, ResetPasswordUserModelForm
def user_list(request):
"""
用户列表
:param request:
:return:
"""
user_queryset = models.Userinfo.objects.all().order_by("pk")
return render(request, "rbac/user_list.html", {"users": user_queryset})
def user_add(request):
"""
添加用户
:param request:
:return:
"""
if request.method == "GET":
form = UserModelForm()
return render(request, "rbac/change.html", {"form": form})
form = UserModelForm(data=request.POST) # 保存
if form.is_valid():
form.save()
return redirect(reverse("rbac:user_list"))
return render(request, "rbac/change.html", {"form": form})
def user_edit(request, pk):
"""
用户编辑
:param request:
:param pk: 要修改的用户ID
:return:
"""
obj = models.Userinfo.objects.filter(id=pk).first()
if not obj:
return HttpResponse("用户不存在...")
if request.method == "GET":
form = UpdateUserModelForm(instance=obj) # 将原有的数据展示
return render(request, "rbac/change.html", {"form": form})
form = UpdateUserModelForm(instance=obj, data=request.POST) # 保存编辑后的数据
if form.is_valid():
form.save()
return redirect(reverse("rbac:user_list"))
return render(request, "rbac/change.html", {"form": form})
def user_del(request, pk):
"""
删除用户
:param request:
:param pk:
:return:
"""
origin_url = reverse("rbac:user_list")
if request.method == "GET":
return render(request, "rbac/delete.html", {"cancel_url": origin_url})
models.Userinfo.objects.filter(id=pk).delete()
return redirect(origin_url)
def user_reset_pwd(request, pk):
"""
重置密码
:param request:
:param pk:
:return:
"""
obj = models.Userinfo.objects.filter(id=pk).first()
if not obj:
return HttpResponse("用户不存在...")
if request.method == "GET":
form = ResetPasswordUserModelForm() # 重置密码，不需要把之前的密码进行展示
return render(request, "rbac/change.html", {"form": form})
form = ResetPasswordUserModelForm(instance=obj, data=request.POST) # 保存编辑后的数据
if form.is_valid():
form.save()
return redirect(reverse("rbac:user_list"))
return render(request, "rbac/change.html", {"form": form})
第四步：模板的创建(change.html和delete.html都是共用的，所以只需要创建一个展示用户的html即可)
rbac/templates/rbac/user_list.html
{% extends 'layout.html' %}
{% block content %}
<div class="luffy-container">
<div class="btn-group" style="margin: 5px 0">
<a class="btn btn-default" href="{% url 'rbac:user_add' %}">
<i class="fa fa-plus-square" aria-hidden="true"></i> 添加用户
</a>
</div>
<table class="table table-bordered table-hover">
<thead>
<tr>
<th>序号</th>
<th>用户名</th>
<th>邮箱</th>
<th>重置密码</th>
<th>操作</th>
</tr>
</thead>
<tbody>
{% for row in users %}
<tr>
<td>{{ forloop.counter }}</td>
<td>{{ row.name }}</td>
<td>{{ row.email }}</td>
<td>
<a href="{% url 'rbac:user_reset_pwd' pk=row.id %}">重置密码</a>
</td>
<td>
<a style="color: #333333;" href="{% url 'rbac:user_edit' pk=row.id %}">
<i class="fa fa-edit" aria-hidden="true"></i></a>
<a style="color: #d9534f;" href="{% url 'rbac:user_del' pk=row.id %}">
<i class="fa fa-trash-o"></i>
</a>
</td>
</tr>
{% endfor %}
</tbody>
</table>
</div>
{% endblock %}
知识点：
- ModelForm
- 字段的自定制
- 钩子函数
- 错误提示变成中文的两种方法
- 重写__init__方法，统一给所有字段添加属性("form-control")
- 根据namespace和name反向生成URL
- 模板的查找顺序
