Interesting 100/100.
Done.

import pandas as pd

def myView(self, request):
    """Handle POST requests, save all data provided in excel file."""
    excel_file = request.FILES.get('excel_one')
    excel_df = pd.read_excel(excel_file)
    data_format = ['Option_1', 'Option_2', 'Option_3', 'Option_4',]
    try:
        formatted_df = excel_df[data_format]
    except KeyError as error:
        return JsonResponse({'success': False, 'message': str(error), })
    # forloop to create model objects
    for i, v in formatted_df.iterrows():
        # do a lot of data validating and stuff first
        MyModels.objects.create(arguments)
        print(f'Created object {i+1}/{len(formatted_df)}!'  # Want to to be sent to html page in real time
    return JsonResponse({'success': True, })

我提出了如下ajax请求:

$.ajax({  // variables url, data, etc. contain the expected stuff
    async: false,
    url: url,
    method: "POST",
    data: data,
    success: function(d){
        if(data.success){
            console.log(d);
         }
         else{
             $('.log').append('<p><b>Error:</b> '+ d.message +'</p>')
         }
     },
     cache: false,
     contentType: false,
     processData: false
});
