Django上传excel表格并将数据写入数据库:
上传文件：
.配置 setting.py
# 文件上传配置
UPLOAD_ROOT = os.path.join(BASE_DIR,'upload')
前端：
使用 <form> 表单提交，"/upload/" 路由配置在 urls 中
{% extends 'base.html' %}
{% block content %}
<body>
<form id="form" enctype="multipart/form-data" action="/upload/" method="post">
<p><input type="file" name="file"></p>
<input type="submit" name="提交">
</form>
</body>
{% endblock %}
后端：
@csrf_exempt
def upload(request):
# 根name取 file 的值
file = request.FILES.get('file')
logger.log().info('uplaod:%s'% file)
# 创建upload文件夹
if not os.path.exists(settings.UPLOAD_ROOT):
os.makedirs(settings.UPLOAD_ROOT)
try:
if file is None:
return HttpResponse('请选择要上传的文件')
# 循环二进制写入
with open(settings.UPLOAD_ROOT + "/" + file.name, 'wb') as f:
for i in file.readlines():
f.write(i)
except Exception as e:
return HttpResponse(e)
return HttpResponse('上传成功')
解析excel 导入数据库：
# 将excel数据写入mysql
def wrdb(filename):
# 打开上传 excel 表格
readboot = xlrd.open_workbook(settings.UPLOAD_ROOT + "/" + filename)
sheet = readboot.sheet_by_index(0)
#获取excel的行和列
nrows = sheet.nrows
ncols = sheet.ncols
print(ncols,nrows)
sql = "insert into working_hours (jobnum,name,workingtime,category,project,date,createtime) VALUES"
for i in range(1,nrows):
row = sheet.row_values(i)
jobnum = row[4]
name = row[5]
workingtime = row[2]
category = row[8]
project = row[1]
date = xldate_as_datetime(row[3],0).strftime('%Y/%m/%d')
values = "('%s','%s','%s','%s','%s','%s','%s')"%(jobnum,name,workingtime,category,project,date,datetime.datetime.now())
sql = sql + values +","
# 为了提高运行效率，一次性把数据 insert 进数据库
sql = sql[:-1]
# 写入数据库
# DataConnection 是自定义的公共模块，用的是第三方库，用来操作数据库。没有用 ORM ，后续有 group by 等复杂 sql 不好操作。
DataConnection.MysqlConnection().insert('work',sql)

try:
