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 ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see:https://docs.djangoproject.com/en/4.1/topics/http/urls/
Examples:
Function views1. Add an import:  from my_app import views2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views1. Add an import:  from other_app.views import Home2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf1. Import the include() function: from django.urls import include, path2. 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, performurlpatterns = [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_safeclass PageData(object):def __init__(self, request, queryset, page_size=10, plus=2, page_param="page"):get_query_dict = deepcopy(request.GET)self.query_dict = get_query_dictself.page_param = page_parampage = request.GET.get(self.page_param, "1")# 判段当前page首部是纯数字if page.isdecimal():page = int(page)else:page = 1self.page = pageself.start = (self.page - 1) * page_sizeself.end = self.page * page_sizeself.page_queryset = queryset[self.start: self.end]page_count = queryset.count()page_count, div = divmod(page_count, page_size)if div:page_count += 1self.page_count = page_countself.plus = plusdef page_html(self):if self.page_count <= 2 * self.plus + 1:start_page = 1end_page = self.page_countelse:# 如果当前点击的页面是小于3的if self.page <= self.plus:start_page = 1end_page = 2 * self.plus + 1else:# 后五页if (self.page + self.plus) > self.page_count:start_page = self.page_count - self.plus * 2end_page = self.page_countelse:# 大于前五页，小于后五也的其他页面start_page = self.page - self.plusend_page = self.page + self.pluspage_str_list = []# 首页self.query_dict.setlist(self.page_param, [1])page_str_list.append(f'<li><a href="?{self.query_dict.urlencode()}">首页</a></li>')# 上一页if self.page > 1:self.query_dict.setlist(self.page_param, [self.page - 1])page_str_list.append(f'<li><a href="?{self.query_dict.urlencode()}"><span aria-hidden="true">«</span></a></li>')else:page_str_list.append(f'<li class="disabled"><span aria-hidden="true">«</span></li>')for page_num in range(start_page, end_page + 1):if page_num == self.page:self.query_dict.setlist(self.page_param, [page_num])page_str_list.append(f'<li class="active"><a href="?{self.query_dict.urlencode()}">{page_num}</a></li>')else:self.query_dict.setlist(self.page_param, [page_num])page_str_list.append(f'<li><a href="?{self.query_dict.urlencode()}">{page_num}</a></li>')# 下一页if self.page < self.page_count:self.query_dict.setlist(self.page_param, [self.page + 1])page_str_list.append(f'<li><a href="?{self.query_dict.urlencode()}"><span aria-hidden="true">»</span></a></li>')else:page_str_list.append(f'<li class="disabled"><span aria-hidden="true">»</span></li>')# 尾页self.query_dict.setlist(self.page_param, [self.page_count])page_str_list.append(f'<li><a href="?{self.query_dict.urlencode()}">尾页</a></li>')search_page = """<li><div style="float: right"><form method="get"><div class="input-group" style="width: 100px;float: right"><input type="text" class="form-control" name="page"><span class="input-group-btn"><button class="btn btn-success" type="submit">跳转</button></span></div></form></div></li>"""page_str_list.append(search_page)page_string = mark_safe("".join(page_str_list))return page_string

perform.py:

from datetime import datetimefrom django.shortcuts import render, redirect
from django import forms
from project_one.utils.PageData import PageData
import osfrom 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:

1. files=request.FILES不能漏加, 因为我们在添加数据的时候, 要上传文件。
2. 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/。
3. 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。
4. 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">{% csrf_token %}{% 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>{{ field }}{#       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 ConfigurationThe `urlpatterns` list routes URLs to views. For more information please see:https://docs.djangoproject.com/en/4.1/topics/http/urls/
Examples:
Function views1. Add an import:  from my_app import views2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views1. Add an import:  from other_app.views import Home2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf1. Import the include() function: from django.urls import include, path2. 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, performurlpatterns = [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><li><a href="/demo/list/">ajax请求</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。

三、代码展示合集
