权限组件（7）：权限分配的用户管理

效果图：

和角色管理差不多，只是把编辑拆分成了编辑用户名、邮箱和重置密码，相应的form验证就会多一些。模板除了多了一个用户列表，增删改用的都是之前的。还有models层的email字段，改成EmailField

一、路由配置

rbac/urls.py

from django.urls import re_path

from rbac.views import user

urlpatterns = [
    # 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')
]

二、Form表单验证

rbac/forms/base.py

from django import forms

class BaseBootStrapForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        for name, field in self.fields.items():
            field.widget.attrs['class'] = 'form-control'

 

rbac/forms/user.py

from django import forms

from rbac.forms.base import BaseBootStrapForm
from rbac import models


class AddUserModelForm(BaseBootStrapForm):
    confirm_password = forms.CharField(
        label='确认密码',
        widget=forms.PasswordInput(attrs={'class': 'form-control'})
    )

    class Meta:
        model = models.UserInfo
        fields = ['username', 'password', 'confirm_password', 'email', ]

        widgets = {
            'password': forms.PasswordInput(),
        }

    def clean(self):
        password = self.cleaned_data['password']
        confirm_password = self.cleaned_data['confirm_password']

        if password and confirm_password:
            if password != confirm_password:
                raise forms.ValidationError('密码不一致')
            else:
                return self.cleaned_data


class UpdateUserModelForm(BaseBootStrapForm):
    class Meta:
        model = models.UserInfo
        fields = ['username', 'email']


class ResetPwdUserModelForm(BaseBootStrapForm):
    confirm_password = forms.CharField(
        label='确认密码',
        widget=forms.PasswordInput(attrs={'class': 'form-control'})
    )

    class Meta:
        model = models.UserInfo
        fields = ['password', 'confirm_password']

        widgets = {
            'password': forms.PasswordInput(),
        }

    def clean(self):
        password = self.cleaned_data['password']
        confirm_password = self.cleaned_data['confirm_password']

        if password and confirm_password:
            if password != confirm_password:
                raise forms.ValidationError('密码不一致')
            else:
                return self.cleaned_data

 

 

三、视图函数

rbac/views/user.py

from django.shortcuts import HttpResponse, render, redirect, reverse

from rbac import models
from rbac.forms.user import AddUserModelForm, UpdateUserModelForm, ResetPwdUserModelForm


def user_list(request):
    user_queryset = models.UserInfo.objects.all()

    return render(request, 'rbac/user_list.html', {'user_list': user_queryset})


def user_add(request):
    if request.method == 'POST':
        form = AddUserModelForm(data=request.POST)
        if form.is_valid():
            form.save()
            return redirect(reverse('rbac:user_list'))
        errors = form.errors.get('__all__')
        return render(request, 'rbac/change.html', {'form': form, 'errors': errors})

    form = AddUserModelForm()
    return render(request, 'rbac/change.html', {'form': form})


def user_edit(request, pk):
    user_obj = models.UserInfo.objects.filter(pk=pk).first()
    if not user_obj:
        return HttpResponse('用户不存在')

    if request.method == 'POST':
        form = UpdateUserModelForm(data=request.POST, instance=user_obj)
        if form.is_valid():
            form.save()
            return redirect(reverse('rbac:user_list'))
        return render(request, 'rbac/change.html', {'form': form})

    form = UpdateUserModelForm(instance=user_obj)
    return render(request, 'rbac/change.html', {'form': form})


def user_del(request, pk):
    user_list_url = reverse('rbac:user_list')

    if request.method == 'GET':
        return render(request, 'rbac/delete.html', {'cancel': user_list_url})
    models.UserInfo.objects.filter(pk=pk).delete()
    return redirect(user_list_url)


def user_reset_pwd(request, pk):
    user_obj = models.UserInfo.objects.filter(pk=pk).first()
    if not user_obj:
        return HttpResponse('用户不存在')

    if request.method == 'POST':
        form = ResetPwdUserModelForm(data=request.POST, instance=user_obj)
        if form.is_valid():
            form.save()
            return redirect(reverse('rbac:user_list'))
        errors = form.errors.get('__all__')
        return render(request, 'rbac/change.html', {'form': form, 'errors': errors})

    form = ResetPwdUserModelForm()
    return render(request, 'rbac/change.html', {'form': form})

 

四、模板

rbac/templates/user_list.html

{% extends 'layout.html' %}

{% block content %}
    <h1>用户列表</h1>
    <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-hover table-striped">
            <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 user in user_list %}
                <tr>
                    <td>{{ forloop.counter }}</td>
                    <td>{{ user.name }}</td>
                    <td>{{ user.email }}</td>
                    <td>
                        <a href="{% url 'rbac:user_reset_pwd' pk=user.id %}">重置密码</a>
                    </td>
                    <td>
                        <a style="color: #333333; font-size:18px" href="{% url 'rbac:user_edit' pk=user.id %}">
                            <i class="fa fa-edit" aria-hidden="true"></i>
                        </a>

                        <a style="color: red; font-size:18px" href="{% url 'rbac:user_del' pk=user.id %}">
                            <i class="fa fa-trash-o" aria-hidden="true"></i>
                        </a>
                    </td>
                </tr>
            {% endfor %}
            </tbody>
        </table>
    </div>
{% endblock content %}
