Question

我想创建将csv数据导入数据库。我在我的应用程序上添加导入按钮。覆盖app / change_list。按钮将被正确添加。我想在点击时添加动作，“导入”按钮文件将被上传到同一模板页面上。并保存数据。我参考链接

Importing data into django from CSV via admin interface

但我不理解管理员流程。我想在弹出窗口中打开文件uploadd选项，如image_file upload。

Answer 1

我编写并使用以下代码：

import csv
def importcsv(request):
     if request.method == "POST":
        form = DataInput(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('Url/')
     else:
        form = DataInput()
        context = {"form": form}
        return render_to_response("imported.html", context,context_instance=RequestContext(request))

在创建的带有

表单的import.html文件中

<form enctype="multipart/form-data" action="" method="post" id="importform">

在admin cookbook网站上有一个很好的上传CSV的例子：

https://books.agiliq.com/projects/django-admin-cookbook/en/latest/import.html

代码如下：

class CsvImportForm(forms.Form):
csv_file = forms.FileField()

@admin.register(Hero)
class HeroAdmin(admin.ModelAdmin, ExportCsvMixin):
...
change_list_template = "entities/heroes_changelist.html"

def get_urls(self):
    urls = super().get_urls()
    my_urls = [
        ...
        path('import-csv/', self.import_csv),
    ]
    return my_urls + urls

def import_csv(self, request):
    if request.method == "POST":
        csv_file = request.FILES["csv_file"]
        reader = csv.reader(csv_file)
        # Create Hero objects from passed in data
        # ...
        self.message_user(request, "Your csv file has been imported")
        return redirect("..")
    form = CsvImportForm()
    payload = {"form": form}
    return render(
        request, "admin/csv_form.html", payload
    )
