表格上传

目录

1.完成上次还遗留下来的修改和删除功能

2.资产表格文件上传功能

3.代码展示集合

这篇文章, 先把上一篇文章剩下的修改和删除功能解决了, 因为绩效表格的修改和删除功能, 和之前的修改删除有一点区别, 不过原理都是一样的, 然后再实现把资产表格文件功能。

一、完成上次还遗留下来的修改和删除功能

绩效修改功能代码:

perform.py:

class PerformModifyModelForm(forms.ModelForm):
class Meta:
model = models.Perform
fields = ["oid"
, "source"
, "title"
, "price"]
def __init__(self, *args, **kwargs):
super(
).__init__(*args, **kwargs)
for name, field in self.fields.items(
):
field.widget.attrs = {
"class": "form-control"
}
def modify_perform(request, nid):
title = "修改绩效信息"
query_set = models.Perform.objects.filter(id=nid).first(
)
if request.method == "GET":
form = PerformModifyModelForm(instance=query_set)
content = {
"form": form, "title": title
}
return render(request, "perform/perform_add_modify.html"
, content)
form = PerformModifyModelForm(data=request.POST, files=request.FILES, instance=query_set)
if form.is_valid(
):
form.save(
)
return redirect("/perform/list/"
)
return render(request, "perform/perform_add_modify.html"
, {
"form": form, "title": title
}
)

这里面需要注意的是, 我们只需要修改oid, source, title, price这四个字段的信息, 其他比如name和image是不能修该的, 因为name就是当前添加信息的那个人的账号名, image是上传的文件, 一般文件上传错了, 得重新上传再修改即可, 无需重新修改文件, 否则修改之后新的文件和之前未修改遗留下来的文件都在, 这样的话就浪费空间了。

绩效删除功能的代码:

perform.py:

def delete_file(request, nid):
# 如果当前这张图片只会出现一次，文件+数据表内容一起删除
# 如果文件出现多次
path_obj = models.Perform.objects.filter(id=nid).first(
)
# 获取当前文件路径
filepath = path_obj.image
# 删除数据
path_obj.delete(
)
try:
# 将文件进行删除(删除数据表格的同时, 也要把项目里面的media对应的文件一并删除)。
os.remove(filepath)
except:
return redirect("/perform/list/"
)
return redirect("/perform/list/"
)

这里删除和之前写过删除的代码, 有些区别, 因为当我们删除数据的时候, 所对应上传的文件也要一并删除, 那这边代码的操作就会比以前多些, 但是删除的原理还是差不多。

添加路由:

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 = [
path('asset/file/'
, assets.asset_file, name="asset_file"
)
,
path("perform/<int:nid>/modify/"
  , perform.modify_perform, name="modify_perform"
  )
  ,
  path("perform/<int:nid>/delete/"
    , perform.delete_file, name="delete_file"
    )
    ]

在前端的修改删除那两个地方加上路由:

perform_list.html:

<a href="/perform/{{ data.id }}/modify"><span style="color: green;" class="glyphicon glyphicon-pencil" aria-hidden="true"></span></a>
<a href="/perform/{{ data.id }}/delete"><span style="color: red;" class="glyphicon glyphicon-trash" aria-hidden="true"></span></a>

修改页面的话, 还是会用到perform_add_modify.html。

perform_add_modify.html代码:

{% 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 %}

二、资产表格文件上传功能

我们需要在资产表格上方在添加数据按钮的右边, 添加一个上传表格的按钮。

<a href="/assets/add/" class="btn btn-success">添加信息</a>
  <button type="button" class="btn btn-success" data-toggle="modal" data-target="#myModal">
  表格上传
</button>
  <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
    <div class="modal-dialog" role="document">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span
            aria-hidden="true">&times;
        </span></button>
      <h4 class="modal-title" id="myModalLabel">选择表格</h4>
      </div>
        <div class="modal-body">
          <form action="/asset/file/" method="post" enctype="multipart/form-data">
          {% csrf_token %}
            <input type="file" name="excel">
          <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button>
          <button type="submit" class="btn btn-primary">提交</button>
          </form>
        </div>
      </div>
    </div>
  </div>

然后我们在后端编写上传表格的代码:

assets.py:

def asset_file(request):
# 上传excel表格
file_object = request.FILES["excel"]
wb = load_workbook(file_object)
sheet = wb.worksheets[0]
for data in sheet.iter_rows(
):
mobile = data[0].value
status = data[1].value
times = data[2].value
price = data[3].value
name = data[4].value
# print(mobile, status, times, price, name)
models.Assets.objects.create(mobile=mobile, status=status, create_time=times, price=price, user_id=name)
return redirect("/assets_list/"
)

这段代码的意思:就是上传一个excel表格, 然后提交成功之后, 数据就会成功的添加到assets表格里面, 那网页里面就可以看到我们添加的数据。这里我们用到了load_workbook, 这个就是用来加载excel表格用的, 这里用到的excel操作, 在博主之前写到的爬虫的文章里面, 有写过使用的方法, 如果不太记得的话, 可以翻一翻以前的文章看看。这里面的逻辑也很简单, 就是获取到上传的excel表格里面的每一列数据, 然后添加到assets表格里面。

配置路由:

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 = [
path('asset/file/'
, assets.asset_file, name="asset_file"
)
]

运行结果:

登录后, 到绩效界面:

点击最后一条数据进行修改:

我们可以发现, 在修改数据框里面, 可以正常获取数据。

现在我们对其进行修改:

提交修改数据:

我们发现修改成功!!!

然后再删除最后一条数据(点击最后一行数据的垃圾桶那个图标):

我们发现, 删除也成功了!!!

我们再桌面创建一个excel文件:

里面输入内容:

注意, 需要在第二列和最后一列输入数字, 因为数据库里面存储的数据是smallint类型的, 第二列里面的1代表已使用, 0代表未使用, 最后一列的数据, 是user_id号(这个是外键)。数据千万不能填错, 否则上传excel会失败从而导致报错。

编辑好数据之后, 我们网页里面打开资产表:

然后点击表格上传:

这里面点击选择文件, 在选择文件的时候, 选择我们刚才创建好的excel表格。

点击提交:

提交后的结果:

会把我们excel表格里面的数据, 添加到表格的尾部。

三、代码展示集合

前端:

好了, 这篇文章关于表格上传已经之前的修改删除功能, 就这样到此结束了, 整个django项目基本也就做的差不多了, 之后的文章, 就会讲整个项目怎么去部署了。

以上就是Django框架的表格上传功能的所有内容了, 如果有哪里不懂的地方,可以把问题打在评论区, 欢迎大家在评论区交流!!!
如果我有写错的地方, 望大家指正, 也可以联系我, 让我们一起努力, 继续不断的进步.
学习是个漫长的过程, 需要我们不断的去学习并掌握消化知识点, 有不懂或概念模糊不理解的情况下,一定要赶紧的解决问题, 否则问题只会越来越多, 漏洞也就越老越大.
人生路漫漫, 白鹭常相伴!!!
