Django自学之 前端HTML上传文件读取文件内容并入库，将入库数据展示在前台页面列表

1.创建工程temp，同时创建app应用song01app

2.在创建的app应用song01app下创建文件目录"templates"——》"song01app"——》"upload_file.html"

3.在创建的app应用song01app下创建urls.py文件

4.在工程temp下的settings.py文件下添加应用名song01app

5.编写temp下的urls.py文件

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('temp/', include('song01app.urls'))
]

6.编写应用song01app下的urls.py文件

from django.urls import path
from song01app import views

urlpatterns = [
    path('upload/', views.upload_file)
]

7.在应用song01app下创建monkey_log_file目录，用于存放上传的日志文件

8.编写upload_file.html

    
    


    

        {% csrf_token %}
        
Monkey 测试
        请输入测试执行人：
        请输入测试版本：

        请上传monkey日志文件

        
        

        测试执行结果：

    
    

        

            

                
ID
                
测试执行人
                
测试版本号
                
ANR异常数
                
Crash异常数
                
Exception异常数
                
是否执行完
                
统计合计
                
备注
            
        
        



        
    

8.编辑song01app下的views.py文件

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def upload_file(request):
    if request.method == "POST":
        File = request.FILES.get("files", None)
        if File is None:
            return HttpResponse("请选择需要上传的monkey日志文件")
        else:
            with open("./song01app/monkey_log_file/%s" % File.name, 'wb+') as  f:
                for chunk in File.chunks():
                    f.write(chunk)
            return render(request, "song01app/upload_file.html")
    else:
        return render(request, "song01app/upload_file.html")

9.编辑song01app应用下的models.py文件

from django.db import models

# Create your models here.
class result(models.Model):
    id = models.AutoField(primary_key=True)
    name = models.CharField(max_length=150, blank=False, help_text='测试执行人')
    version_num = models.PositiveIntegerField(blank=False,  help_text='版本号')
    anr_num = models.IntegerField(blank=True,  help_text='ANR异常数')
    crash_num = models.IntegerField(blank=True,  help_text='crash异常数')
    exception_num = models.IntegerField(blank=True,  help_text='exception异常数')
    monkey_is_finish = models.BooleanField(default=False, help_text='是否正常结束')
    bug_num = models.IntegerField(blank=True, null=False, help_text='bug数量')
    remark = models.CharField(max_length=30, blank=False, null=False, help_text="备注")

10.在应用song01app下创建一个num_count.py文件，用于处理文件中的数据

def _out_log(request):
    contains = json.loads(_open_andreadfile(request))
    people = request.POST.get("peoples", None)
    version = request.POST.get("versions", None)
    if contains:
        models.result.objects.create(bug_num=contains['total'], anr_num=contains['anr'],
                             crash_num=contains['crash'], exception_num=contains['exception'], monkey_is_finish=contains['is_finish'],
                             name=people, version_num=version, remark="写死到备注")
        list = models.result.objects.all()
        return list
    else:
        models.result.objects.create(bug_num=contains['total'], anr_num=contains['anr'],
                             crash_num=contains['crash'], exception_num=contains['exception'],monkey_is_finish=contains['is_finish'],
                             name=people, version_num=version, remark="写死到备注")

def _open_andreadfile(request):
    File = request.FILES.get("files", None)
    log_out_str = "./song01app/monkey_log_file/" + File.name
    log_content = open(log_out_str, "r")
    s = log_content.read()
    anr = s.count('ANR')
    crash = s.count('CRASH')
    exception = s.count('Exception')
    monkey_is_finish = s.count('Monkey finished')
    total = anr+crash+exception
    is_finish = False
    if (monkey_is_finish > 0):
        is_finish = True
    log_content.close()
    _result_list = json.dumps({'anr': anr, 'crash': crash, 'exception': exception, 'is_finish': is_finish, 'total': total})
    return  _result_list

11.修改views.py和upload_file.html文件标红的地方，图1是views.py图2是upload_file.html

代码如下：

return render(request, "song01app/upload_file.html", {"data": _out_log(request).all()})

{% for result in data %}
     
         {{ result.id}}
         {{ result.name }}
         {{ result.version_num }}
         {{ result.anr_num}}
         {{ result.crash_num }}
         {{ result.exception_num }}
         {{ result.monkey_is_finish }}
         {{ result.bug_num }}
         {{ result.remark}}
     
{% endfor %}

12.执行数据库迁移，在终端输入以下两条命令

13.重新启动服务

14.服务器启动成功后在浏览器输入http://127.0.0.1:8000/temp/upload/，自己填写信息上传文档试一下

15.运行上传后的结果如下：
