使用 django 导入 csv 文件 - 表单不出现

Question

我尝试创建一个项目，我需要导入一个 csv 文件 (Import csv file using django - Exception Type: DatabaseError)

我想在其他页面上显示表格，而不是在主页上。但是，当我创建一个新路径时，它并没有显示那个特定的视图。

csvs/urls.py

from django.urls import path
from .views import upload_file_view
app_name='csvs'

urlpatterns =[
    path('import/', upload_file_view, name='upload-view') 
]

csvs/views.py

from django.shortcuts import render
from .forms import CsvModelForm
from .models import Csv
import csv
from django.contrib.auth.models import User
from sales.models import Sales

def upload_file_view(request):
        form = CsvModelForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            form = CsvModelForm()

            obj= Csv.objects.get(activated=False)
            with open(obj.file_name.path, 'r') as f:
                reader = csv.reader(f)

                for i, row in enumerate(reader):
                    if i==0: 
                        pass
                    else: 
                        #row = "".join(row)
                        #row = row.replace(";"," ")
                        #row=row.split()

                        #print(row)
                        #print(type(row))
                        date = row[1]
                        user = User.objects.get(username=row[0])
                        Sales.objects.create(
                            date=date,
                            product= row[2],
                            user=user,
                        )
                obj.activated=True
                obj.save()
        return render(request, 'upload.html', {
        'form': form
    })

主文件 - urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
from sales.views import import_view, home_view
urlpatterns = [
    path('admin/', admin.site.urls),
    path('import/', import_view, name="import"),
    path('', home_view, name="home"),

    path('import/', include('csvs.urls', namespace='csvs')),
]

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

sales/views.py

from django.shortcuts import render

# Create your views here.

def import_view(request, *args, **kwargs): 
    return render(request, "import.html", {})

def home_view(request, *args, **kwargs): 
    return render(request, "home.html", {})

如果我删除上面的视图（导入、主页），我为 home.html 准备的模板，然后从 csvs.urls.py 中删除'import/' 并从 主文件中删除相同的内容 - urls.py，如下所示：path('', include('csvs.urls', namespace='csvs')), 表格显示在首页, 其他情况下没有.

我尝试更改 csvs/view.py 的最后一行并放入 'import.html' 并在 import.html 中具有相同的代码它在 upload.html 中，但仍然没有。

upload.html

{% extends 'base.html' %}
{% block title %}Import{% endblock %}

{% block content%}
<h1>Import</h1>
<form method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    {{form.as_p}}
    <button type="submit">Confirm</button>
</form>
{% endblock%}

我真的卡住了。我想继续我的项目，但我不知道如何解决所有这些问题。我是 django 的新手，mongodb.

非常感谢您的宝贵时间！

备注

据我阅读你的代码，main-urls.py 中的问题将得到解决，但你必须决定 sales.urls 或 [=13] 中的 import/ =]

在main-urls.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
from sales.views import import_view, home_view

othor_urls = [
    # This is for all csvs urls
    path('csvs/', include('csvs.urls')),
    # This is for all sales urls
    path('sales/', include('sales.urls')),
]

urlpatterns = [
    path('admin/', admin.site.urls),
    # Remove import/ as it is move to other_urls
    # path('import/', import_view, name="import"),
    path('', home_view, name="home"),
    path('import/', include(othor_urls)),
    # Also remove this whihc is moved to other_urls
    # path('import/', include('csvs.urls', namespace='csvs')),
]

urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

使用 django 导入 csv 文件 - 表单不出现

python

django

django-views

django-templates
