文件上传
目录
1. 配置文件上传的路径
2. 实现上传文件功能
3.代码展示集合
这篇文章, 我们会讲到如何去上传文件。里面的细节点, 需要注意下, 博主就在配置文件上, 卡了很长时间的bug, 这篇文章里面也会讲到博主遇到bug的点。
一、配置文件上传的路径
我们打开settings.py:
在最后面加上两行代码:
import os
MEDIA_ROOT = os.path.join(BASE_DIR, "media")
MEDIA_URL = "/media/"
这两行代码, 是用来设置将来文件上传玩以后, 把上传好的文件放到哪里, 我们在那两行代码的配置信息里面不难看出, 我们是将上传好的文件, 都存放在media文件夹里面。
我们在项目的根目录下新建一个media文件夹。
然后我们还需要文件上传的相应路由:
urls.py:
"""project_simple URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/4.1/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path, re_path
from django.views.static import serve
from django.conf import settings
from project_one.views import depart, user, assets, admin_role, login, Ajax_data, task_data, perform
urlpatterns = [
re_path(r"^media/(?P<path>.*)$", serve, {"document_root": settings.MEDIA_ROOT})
]
这里运用了正则表达式, 来匹配要访问文件的路由, 用正则表达式^media/(?P<path>.*)$ 来表示。
这里面需要导入以下包:
1.from django.urls import path, re_path
2.from django.views.static import serve
3.from django.conf import settings
以上两个步骤, 在做今天的项目之前, 一定要配置好, 不然到后面调试程序的时候, 都不清楚哪里报错了, 博主就是因为这个问题, 卡了很久。。。。。。
二、实现上传文件功能
创建数据库表格Perform(这个是记录业绩的表格):
models.py:
class Perform(models.Model):
oid = models.CharField(verbose_name="订单号", max_length=32)
source = models.CharField(verbose_name="销售", max_length=32)
title = models.CharField(verbose_name="客户姓名", max_length=32)
times = models.DateField(verbose_name="成交日期")
price = models.CharField(verbose_name="成交金额", max_length=32)
name = models.CharField(verbose_name="销售人员", max_length=32)
image = models.CharField(verbose_name="详情", max_length=128)
我们先要实现页面展示功能:
perform_list.html:
{% extends "index/model_tmp.html" %}
{#{% load static %}#}
{% block content %}
<div class="container">
<a href="/perform/add/" class="btn btn-success">添加信息</a>
<div class="panel panel-success">
<div class="panel-heading">
<h3 class="panel-title">绩效表</h3>
</div>
<div class="panel-body">
<table class="table table-bordered">
<thead>
<tr>
<th>ID</th>
<th>订单号</th>
<th>客户来源</th>
<th>客户名称</th>
<th>成交时间</th>
<th>成交价格</th>
<th>销售人员</th>
<th>详情</th>
{% if request.unicom_role == 3 %}
<th>操作</th>
{% endif %}
</tr>
</thead>
<tbody>
{% for data in perform_list %}
<tr>
<th scope="row">{{ data.id }}</th>
<th>{{ data.oid }}</th>
<th>{{ data.source }}</th>
<th>{{ data.title }}</th>
<th>{{ data.times }}</th>
<th>{{ data.price }}</th>
<th>{{ data.name }}</th>
<th>
<div><a target="_blank" href="/{{ data.image }}/" style="width: 60px; height: 60px;"><img style="object-fit: cover; border-radius: 100px;" src="/{{ data.image }}/" width="60" height="60" alt="图片无法加载"></a></div>
</th>
{% if request.unicom_role == 3 %}
<td style="color: green">
<a href="#"><span style="color: green;" class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a>
<a href="#"><span style="color: red;" class="glyphicon glyphicon-trash" aria-hidden="true"></span></a>
</td>
{% endif %}
</tr>
{% endfor %}
</tbody>
</table>
</div>
</div>
{# 实现分页查询 #}
<ul class="pagination">
{{ page_string }}
</ul>
</div>
{% endblock %}
PageData.py（这个代码之前写过, 这篇文章中需要用到此代码）:
from copy import deepcopy
from django.utils.safestring import mark_safe
class PageData(object):
def __init__(self, request, queryset, page_size=10, plus=2, page_param="page"):
get_query_dict = deepcopy(request.GET)

page = request.GET.get(self.page_param, "1")
# 判段当前page首部是纯数字

if self.page <= self.plus:
start_page = 1
end_page = 2 * self.plus + 1
else:
# 后五页
if (self.page + self.plus) > self.page_count:
start_page = self.page_count - self.plus * 2
end_page = self.page_count
else:

page_str_list.append(search_page)
page_string = mark_safe("".join(page_str_list))
return page_string
perform.py:
from datetime import datetime
from django.shortcuts import render, redirect
from django import forms
from project_one.utils.PageData import PageData
import os
from project_one import models
# Create your views here.
def perform_info(request):
perform_list = models.Perform.objects.all()
# 这个PageData分页, 在utils代码里面。
page_object = PageData(request, perform_list)
content = {
"perform_list": page_object.page_queryset,
"page_string": page_object.page_html()
}
return render(request, "perform/perform_list.html", content)
绩效数据添加功能:
我们先自定义form:
class PerformForm(forms.Form):
oid = forms.CharField(label="订单号",
widget=forms.TextInput(attrs={"class": "form-control", "autocomplete": "off"}))
source = forms.CharField(label="客户来源",
widget=forms.TextInput(attrs={"class": "form-control", "autocomplete": "off"}))
title = forms.CharField(label="客户名称",
widget=forms.TextInput(attrs={"class": "form-control", "autocomplete": "off"}))
price = forms.CharField(label="成交价格",
widget=forms.TextInput(attrs={"class": "form-control", "autocomplete": "off"}))
image = forms.FileField(label="详情")
这里我们没有写class Meta这个类, 所以我们需要用到Form而不是ModelForm。
添加函数:
def add_perform(request):
if request.method == "GET":
title = "添加绩效"
form = PerformForm()
content = {"title": title, "form": form}
return render(request, "perform/perform_add_modify.html", content)
# 如果要上传文件的话, request.FILES千万不能漏掉
form = PerformForm(data=request.POST, files=request.FILES)
if form.is_valid():
# 获取提交过来的文件对象
image_object = form.cleaned_data.get("image")
# 拼接路径
# image_object.name这个就是文件名字,
# os.path.join("media", image_object.name)就代表用media文件夹拼接文件名字,
# 也就是把路径变为:文件夹/文件名。
# 但是最后的路径为:文件夹\文件名。所以需要把\替换成/, 注意要写成\\,
# 因为反斜杠它在正则表达式里面本身就有自己的意义, 所以这里需要转义操作。
print(os.path.join("media", image_object.name))
file_path = os.path.join("media", image_object.name).replace("\\", "/")
print(file_path)
# 将文件存储在media目录当中
with open(file_path, "wb") as file:
for chunk in image_object.chunks():
file.write(chunk)
oid = form.cleaned_data.get("oid")
source = form.cleaned_data.get("source")
title = form.cleaned_data.get("title")
times = datetime.now().strftime("%Y-%m-%d")
price = form.cleaned_data.get("price")
name = request.session['info']['username']
models.Perform.objects.create(oid=oid, source=source, title=title, times=times, price=price, name=name, image=file_path)
return redirect("/perform/list/")
return render(request, "perform/perform_add_modify.html", {"form": form})
这里有些细节需要注意:
- files=request.FILES不能漏加, 因为我们在添加数据的时候, 要上传文件。
- 拼接路径的写法, 利用os.path.join来实现, 最后不要忘记用replace函数把反斜杠\替换成斜杠/。
- 将文件存储到media里面, 需要用到文件存储的代码, 里面用chunk来遍历存储, 因为只有request请求, 才具有.content存储, 那这里, 我们只能用chunk来解决。
- 添加数据, 需要获取到相关的所有数据, oid订单号, source客户来源, title客户名称, times成交时间(获取当前时间, 然后再用年-月-日的格式存储), price成交价格, name销售人员, image就是file_path(文件路径)。
perform_add_modify.html:
{% extends "index/model_tmp.html" %}
{% load static %}
{% block css %}
<link rel="stylesheet" href="{% static 'css/layui.css' %}">
{% endblock %}
{% block content %}
<div class="container">
<h1>{{ title }}</h1>
{# 由于我们enctype="multipart/form-data"必须要加 #}
<form method="post" enctype="multipart/form-data">

{% for field in form %}
{# field.label这里面就是获取我们在models.py里面创建表格里面的每一个字段里面有个verbose_name这个参数的值 #}
<label for="exampleInputEmail1">{{ field.label }}</label>

{# 展示错误信息 #}
<span style="color: red">{{ field.errors.0 }}</span>
<br>
{% endfor %}
<button type="submit" class="btn btn-success">提交</button>
</form>
</div>
{% endblock %}
这里面也有个细节需要注意下, 由于我们需要再添加数据的时候, 上传文件, 那我们就需要在form表单里面, 加上enctype="multipart/form-data"。
最后我们不要忘记添加路由:
urls.py:
"""project_simple URL Configuration

"""
from django.contrib import admin
from django.urls import path, re_path
from django.views.static import serve
from django.conf import settings
from project_one.views import depart, user, assets, admin_role, login, Ajax_data, task_data, perform
urlpatterns = [
re_path(r"^media/(?P<path>.*)$", serve, {"document_root": settings.MEDIA_ROOT})
path("perform/list/", perform.perform_info, name="perform_info"),
path("perform/add/", perform.add_perform, name="add_perform")
]
还有, 不要忘记在model_tmp.html的header里面添加绩效那栏。
<ul class="nav navbar-nav">
{% if request.unicom_role == 1 %}
<li class="active"><a href="/depart/">部门页面</a></li>
<li class="active"><a href="/user/">员工页面</a></li>
{% elif request.unicom_role == 3%}
<li class="active"><a href="/depart/">部门页面</a></li>
<li class="active"><a href="/user/">员工页面</a></li>
<li class="active"><a href="/assets_list/">资产页面</a></li>
{% endif %}
{# <li class="active"><a href="/depart/">部门页面</a></li>#}
{# <li class="active"><a href="/user/">员工页面</a></li>#}
{# <li class="active"><a href="/assets_list/">资产页面</a></li>#}
<li class="dropdown">
{% if request.unicom_role == 3 %}
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true"
aria-expanded="false">平台用户<span class="caret"></span></a>
{% endif %}
<ul class="dropdown-menu">
<li><a href="/admin_list/">登录账号</a></li>

</ul>
</li>
<li class="active"><a href="/task/list/">任务列表</a></li>
<li class="active"><a href="/perform/list/">绩效</a></li>
</ul>
运行结果:
我们登录管理员账号之后, 在上面的导航栏里面点击绩效:
然后点击添加信息:
文件的话, 自己随便从电脑里面选择一个文件。
提交(添加)数据:
数据添加成功!!!
我们再点击一下详情:
会帮我们打开我们上传的文件, 我们这里上传的是图片。
