1.crm

客户关系管理系统 :1.业务逻辑部分 2.权限插件

2.forms组件之modelform

modelform就是model+form ，form根据model的字段生成标签 ，校验信息以及记录的功能 ,一步提交所有数据功能

使用方法：

1)定义个类继承forms.modelform

2)定义哪些字段生成标签fields = '\_\_all\_\_'所有标签

3)定义错误信息以字典的格式

4)重写init方法使用插件给标签更新属性

5)实例化modelform时候 ,如果是对已有对象进行修改需要添加 **instance = 已有对象这个参数** ,指定修改对象生成前段标签

6)is\_valid()通过后可以直接使用 obj.save()提交数据

####model
    class Dep(models.Model):
        name = models.CharField(max_length=32, verbose_name='部门')           #前端的显示label等于verbose_name
        desc = models.CharField(max_length=128, verbose_name='描述')
    
    
    
    ####view
    from django import forms
    
    # Create your views here.
    class DepForm(forms.ModelForm):
        # 也可以重写modle中已有的字段！
        # name = forms.CharField()
        class Meta:
            model = models.Dep
            fields = '__all__'
    　　　　　#exclude = []　　　　　　#排除字段

error_messages = {            #给每个字段定义错误提示
                'name':{
                    'required': '必填项'
                },
                'desc':{
                    'required': '必填项'
                }
            }
    
        def __init__(self, *args, **kwargs):            #定义字段生成标签的属性！
            super(DepForm, self).__init__(*args, **kwargs)
            for field in self.fields.values():
                field.widget.attrs.update({
         'class': 'form-control'})
    
    
    def depadd(request):
        form_obj = DepForm()
        if request.method == 'POST':
            form_obj = DepForm(request.POST)
            if form_obj.is_valid():
                form_obj.save()    
                return redirect(reverse('crm:deplist'))
            print()
        return render(request, 'depadd-edit.html', {
        'form_obj': form_obj})

def depedit(request, edit_id):
        obj = models.Dep.objects.filter(pk=edit_id).first()
        form_obj = DepForm(instance=obj)
        if request.method == 'POST':
            form_obj = DepForm(request.POST, instance=obj)
            if form_obj.is_valid():
                form_obj.save()
                return redirect(reverse('crm:deplist'))
        return render(request, 'depadd-edit.html', {'form_obj': form_obj})

3.优化删除功能使用alter弹窗提示

异步思想: 删除点击后弹出框提示是否删除 ,如果删除前端移除该行记录 ,数据库中删除该条记录 (sweetalter + ajax + 前端js删除父级标签)

4.密码加密处理

用户输入两次密码 ，如果成功 ，直接使用md5加密存放在数据库中 。所以用户输入的密码永远先做md5的处理
