python+django+layui开发页面表格数据的增删改查

下载安装django，见之前文章

前台页面展示：

 

 

一、项目目录结构

 

 

 二、主页面settings需要修改地方

1、子页面需要添加到主app

 

 

 2、数据库设置

 

 

 3、settings底部静态资源配置

 

 

 

三、以device子页面为例

1、device数据库模版

 

 代码：

from django.db import models

class device(models.Model):

    device_id =models.CharField(max_length=50)
    brand =models.CharField(max_length=50)
    model =models.CharField(max_length=50)
    version =models.CharField(max_length=50)
    screen =models.CharField(max_length=50)
    size =models.CharField(max_length=50)
    oa_p =models.CharField(max_length=50)

2、url路由配置

testgroup主页面url：

from django.urls import path, include
from . import views
urlpatterns = [
    path('testgroup/',views.index),
    path('testgroup/welcome',views.welcome),
    path('testgroup/device',include('device.urls')),#连接为testgroup/device时，url跳转到子页面device的url

]

device子页面的url：

from django.urls import path,re_path
from device import views
from dailyreport import tests
urlpatterns = [
    path('',views.device_list), #url的device后无参数时，调用页面
    path('/getdata',views.get_data), #查询数据
    path('/adddata',views.add_data), #新增数据
    path('/deldata',views.del_data), #删除数据
    path('/editdata',views.edit_data), #编辑数据
]

3、views接口

from django.http import JsonResponse
from django.shortcuts import render

from device.models import device

#展示设备管理页面
def device_list(request):
    return render(request, 'device_list.html')

#获取设备列表数据

        device_id = request.GET.get('device_id',"")
        data = []
        if brand != '' and oa_p != '' and device_id == '': #根据品牌和oa所属人查询
            result = device.objects.filter(brand=brand,oa_p=oa_p)
        elif brand != '' and oa_p == '' and device_id == '': #根据品牌查询
            result = device.objects.filter(brand=brand)
        elif brand == '' and oa_p != '' and device_id == '': #根据oa所属人查询
            result = device.objects.filter(oa_p=oa_p)
        elif device_id != '' and brand == '' and oa_p == '': #根据设备id查询
            result = device.objects.filter(device_id=device_id)
        elif device_id != '' and brand != '' and oa_p == '':
            result = device.objects.filter(device_id=device_id,brand=brand)
        elif device_id != '' and oa_p != '' and brand == '':
            result = device.objects.filter(device_id=device_id,oa_p=oa_p)
        elif brand != '' and oa_p != '' and device_id != '':
            result = device.objects.filter(device_id=device_id,brand=brand,oa_p=oa_p) #根据三项条件交集查询
        else:
            result = device.objects.filter() #无查询条件，返回所有数据

        for i in range(len(result)):
            event = {}
            event['id'] = result[i].id
            event['device_id'] = result[i].device_id
            event['brand'] = result[i].brand
            event['model'] = result[i].model
            event['version'] = result[i].version
            event['screen'] = result[i].screen
            event['size'] = result[i].size
            event['oa_p'] = result[i].oa_p
            data.append(event)
        count = len(data)
        if count != 0:
            return JsonResponse({'code':0,'message':'查询成功','count':count,'data':data})
        else:
            return JsonResponse({'code':0,'message':'暂无数据'})

#新增设备
def add_data(request):
    if request.method == 'POST':
        device_id = request.POST.get('device_id', "")
        brand = request.POST.get('brand', "")

        screen = request.POST.get('screen', "")
        size = request.POST.get('size', "")
        oa_p = request.POST.get('oa_p', "")
        if device_id == '' or brand == '' or model == '' or version == '' or oa_p == '':
            return JsonResponse({'code': 10021, 'message': '参数错误'}, json_dumps_params={'ensure_ascii': False})

        device.objects.create(device_id=device_id, brand=brand, model=model, version=version,screen=screen,size=size,oa_p=oa_p)
        return JsonResponse({'code': 0, 'message': '添加成功！'})

#编辑设备
def edit_data(request):
    if request.method == 'POST':
        id = request.POST.get('id',"")
        device_id = request.POST.get('device_id', "")
        brand = request.POST.get('brand', "")
        model = request.POST.get('model', "")
        version = request.POST.get('version', "")
        screen = request.POST.get('screen', "")
        size = request.POST.get('size', "")
        oa_p = request.POST.get('oa_p', "")
        obj = device.objects.filter(id=id)[0]
        try:

            obj.brand = brand
            obj.model = model

            obj.size = size
            obj.oa_p = oa_p
            obj.save()
            return JsonResponse({'code':0,'message':'修改成功!'})
        except objectDoesNotExist:
            return JsonResponse({'status': 10023, 'message': '数据不存在'})

#删除设备
