08-项目实战-手机号管理

# 1. 依赖工具类 bootstrap.py  -bootstrap
# 2. 依赖工具类 pagemtion.py -分页

1. 创建手机号表

# app-->models.py
 
from django.db import models
class Phone(models.Model):
    """用户手机号"""
    phone = models.CharField(verbose_name="手机号", max_length=64)
    # 想要允许为空,null=True,blank=True;  default:默认值
    number = models.IntegerField(verbose_name="登陆次数", default=0)
 
    level_choices = (
        (1, "用户"),
        (2, "超级管理员")
    )
    level = models.SmallIntegerField(verbose_name="类别", choices=level_choices, default=1)
 
    status_choices = (
        (1, "正常"),
        (2, "异常")
    )
    status = models.SmallIntegerField(verbose_name="状态", choices=status_choices, default=1)
 
# python manage.py makemigrations
# python manage.py migrate
 

2. 创建路由(url)

# 项目-->urls.py
# 手机号管理
from bbc_list.views import login, home_page, order, phone
urlpatterns = [
    path("phone/list/", phone.phone_list),
    path("phone/add/", phone.phone_add),
    path("phone/<int:nid>/update/", phone.phone_update),
    path("phone/<int:nid>/delete/", phone.phone_delete),]
 

3. 将ModelForm封装到其他文件

# app-->utils-->form.py
 
from django import forms
from bbc_list import models
from bbc_list.utils.bootstrap import BootStrapModelForm
 
class PhoneModelForm(BootStrapModelForm):
    """新增"""
    # 进行格式的效验,第一种:字段+正则
    from django.core.validators import RegexValidator
    phone = forms.CharField(label="手机号",
                            validators=[RegexValidator(r'1[3-9]\d{9}$', '手机号格式错误'), ],
                            )  # 使用正则效验,不符合提示错误信息
 
    #
    class Meta:
        model = models.Phone
        fields = ['phone', 'number', 'level', 'status']
        # fields = "__all__"  # 所有字段
        # exclude = ["level"]  # 排除那个字段
 
    # 第二种效验:钩子方法,clean_字段名
    def clean_phone(self):
        from django.core.validators import ValidationError
        txt = self.cleaned_data["phone"]  # self.cleaned_data["字段"]:获取用户传入的数据
        exists = models.Phone.objects.filter(phone=txt).exists()  # .exists() : 判断用户输入的手机号是否已存在
 
        # 验证不通过抛给前端一个异常
        if exists:
            raise ValidationError("手机号已存在")  # 返回前端异常信息
 
        # 验证通过,把用户输入的值返回
        return txt
 
 
class PhoneUpdateModelForm(BootStrapModelForm):
    """修改"""
    # phone= forms.CharField(disabled=True, label="手机号")  # 设置不可更改
 
    from django.core.validators import RegexValidator
    phone = forms.CharField(
        label="手机号",
        validators=[RegexValidator(r'1[3-9]\d{9}$', "手机号格式错误")]
    )
 
    class Meta:
        model = models.Phone
        fields = ['phone', 'number', 'level', 'status']  # 只显示里面有的数据
 
    # 效验第二种: 钩子方法 clean_字段名
    def clean_phone(self):
        from django.core.validators import ValidationError
 
        # 当前编辑的哪一行ID
        print("instance.pk==", self.instance.pk)  # 固定语法:instance:对象;pk:id
 
        txt = self.cleaned_data["phone"]  # 获取用户传入的数据
        exists = models.Phone.objects.exclude(id=self.instance.pk).filter(phone=txt).exists()  # 排除自己,判断用户输入的手机号是否已存在
        # 验证不通过,抛给前端一个异常
        if exists:
            raise ValidationError("手机号已存在")  # 返回前端异常信息
 
        # 验证通过,把用户输入的值返回
        return txt
 

4. 编写视图函数

# app-->views-->phone.py
 
from django.shortcuts import render, redirect
 
from bbc_list import models
from bbc_list.utils.form import PhoneModelForm, PhoneUpdateModelForm
 
 
def phone_list(request):
    """手机号列表"""
 
    data_dict = {}
    search_data = request.GET.get("q", "")  # 搜索: 有值的话拿值,没值空字符串
    # print("search_data===", search_data)
    if search_data:
        data_dict["phone__contains"] = search_data  # mobile__contains: 手机号__模糊搜索
 
    # 导入分页
    from bbc_list.utils.pagemtion import Pagination
    # select * from 表 order by level desc;  django里直接输入表字段正序; -字段:倒叙;
    queryset = models.Phone.objects.filter(**data_dict).order_by("-level")
 
    page_object = Pagination(request, queryset)
    context = {
        "search_data": search_data,
 
        "phone": page_object.page_queryset,  # 分完页的所有数据
        "page_string": page_object.html()  # 页码
 
    }
 
    return render(request, "phone_list.html", context)
 
 
def phone_add(request):
    """添加手机号"""
    if request.method == "GET":
        form = PhoneModelForm()
 
        return render(request, "phone_add.html", {"form": form})
 
    form = PhoneModelForm(data=request.POST)
    if form.is_valid():
        form.save()
        return redirect("/phone/list/")
 
    return render(request, "phone_add.html", {"form": form})
 
 
def phone_update(request, nid):
    """修改手机号"""
    row_object = models.Phone.objects.filter(id=nid).first()
    if request.method == "GET":
        form = PhoneUpdateModelForm(instance=row_object)  # 传入数据库对象，用于在界面展示原有数据
        return render(request, "phone_update.html", {"form": form})
 
    form = PhoneUpdateModelForm(data=request.POST, instance=row_object)
 
    if form.is_valid():
        form.save()
        return redirect("/phone/list/")
 
    return render(request, "phone_update.html", {"form": form})
 
 
def phone_delete(request, nid):
    """删除手机号"""
    models.Phone.objects.filter(id=nid).delete()
    return redirect("/phone/list/")
 
 

5. 编写html页面

# phone_list.html
 
{% extends 'one.html' %}
 
{% block content %}
<div class="container">
    <div style="margin-bottom:10px;" class="clearfix">
        <a class="btn btn-success" href="/phone/add/">
            <span class="glyphicon glyphicon-plus" aria-hidden="true">
                新建手机号</span></a>
 
        <div style="float:right;width:300px;">
            <form method="post">
                {% csrf_token %}
                <div class="input-group">
                    <input type="text" name="q" class="form-control" placeholder="Search for..."
                           value="{{ search_data }}">
                    <span class="input-group-btn">
                    <button class="btn btn-default" type="submit">
                        <span class="glyphicon glyphicon-search" aria-hidden="true"></span>
                    </button>
 
                    </span>
 
                </div>
            </form>
        </div>
 
        <a class="btn btn-success" href="/phone/add/">
            <span class="glyphicon glyphicon-plus" aria-hidden="true">
                新建手机号ModelForm</span></a>
    </div>
    <div class="panel panel-default">
        <div class="panel-heading">
            <span class="glyphicon glyphicon-th-list" aria-hidden="true">
                手机号列表
            </span>
        </div>
 
        <table class="table table-bordered">
            <thead>
            <tr>
                <th>ID</th>
                <th>手机号</th>
                <th>登陆次数</th>
                <th>类别</th>
                <th>状态</th>
            </tr>
            </thead>
            <tbody>
            {% for obj in phone %}
            <tr>
                <th>{{ obj.id }}</th>
                <th>{{ obj.phone }}</th>
                <th>{{ obj.number }}</th>
                <!-- {{ obj.get_表字段_display }}获取定义的限制文字  -->
                <td>{{ obj.get_level_display }}</td>
                <td>{{ obj.get_status_display }}</td>
                <td>
                    <a class="btn btn-primary btn-xs" href="/phone/{{ obj.id }}/update/">编辑</a>
                    <a class="btn btn-danger btn-xs" href="/phone/{{ obj.id }}/delete/">删除</a>
                </td>
            </tr>
            {% endfor %}
            </tbody>
        </table>
    </div>
    <div class="clearfix">
        <ul class="pagination">
            {{ page_string }}
        </ul>
    </div>
 
</div>
