Question

场景：用户上传CSV文件，并在后端将CSV保存为文件。现在，我正在尝试将那些csv文件以表格式保存在数据库中。当csv保存数据库时，它将显示类似pandas dataframe的数据。

我已经看到了django-import-export之类的一些软件包。但这不是我想要的。最主要的是，在该程序包中，在上传文件之前先创建模型。但是我不会在用户上传文件之前创建模型。

这是我的django代码。

model.py


from django.db import models

# Create your models here.
from django.db import models

# Create your models here.


class DataUpload(models.Model):
    fileId = models.AutoField(primary_key=True)
    data_upload = models.FileField(upload_to='files/')

    class Meta:
        db_table = 'DataUpload'

forms.py


from django import forms
from .models import DataUpload

class PostForm(forms.ModelForm):
    class Meta:
        model = DataUpload
        fields = ['data_upload']

urls.py


from django.urls import path
from .views import dataview , FileView, ResultView
# from .views import BonolothaDataView
urlpatterns = [
    path('', dataview.as_view()),
    path('fileview/', FileView.as_view(), name='fileview'),
    path('result/', ResultView.viewResult, name='result'),
    # path('bonolotha/', BonolothaDataView.as_view(), name='bonolotha'),



]

views.py


class dataview(View):

    model = DataUpload
    form_class = PostForm

    initial = {'key': 'value'}
    template_name = 'post.html'

    fileview_url = reverse_lazy('fileview')


    def get(self, request, *args, **kwargs):

        form = self.form_class(initial=self.initial) # pribt html form 
        return render(request, self.template_name, {'form':form})

    def post(self, request, *args, **kwargs):

        form = self.form_class(request.POST, request.FILES)
        context = {
            'form': form,
        }

        if form.is_valid():
            form.save()
            return redirect(self.fileview_url)
        else:
            form = self.form_class()    
        return render(request, self.template_name, context)

是否有任何包或函数以数据库表格式保存csv文件
