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　　

　　url部分

###url

from django.conf.urls import url, include

from django.contrib import admin

from crm.view import user, dep

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^user/list/', user.userlist, name='userlist'),

    url(r'^user/add/', user.useradd, name='useradd'),

    url(r'^user/edit/(\d+)/', user.useredit, name='useredit'),

    url(r'^user/del/(\d+)/', user.userdel, name='userdel'),

    url(r'^dep/list/', dep.deplist, name='deplist'),

    url(r'^dep/add/', dep.depadd, name='depadd'),

    url(r'^dep/edit/(\d+)/', dep.depedit, name='depedit'),

    url(r'^dep/del/(\d+)/', dep.depdel, name='depdel'),

]
