如何使用django-import-export将数据从csv导入模型？

Question

I've made some researches about django-import-export, but the most of example I have found are using django admin.. I'm trying to import data to a django model from my template (when clicking on a button a modal appears to choose file location and then submit ),

I feel lost and I don't know how to start..

This is the model I have :

class Musician(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    instrument = models.CharField(max_length=100) 

could someone guide me by giving the steps to follow ?

Thanks in advance !

I have not used django-import-export but writing a view for CSV generation is not difficult using python's built-in csv module.

Django docs also have a section on outputting csv .

Following is a snippet based on example provided in docs:

import csv
from django.http import HttpResponse
from django.views.generic import View

class CsvExportView(View):

    def get(self, request):
        # create a response object
        response = HttpResponse(content_type='text/csv')
        # assign a filename for csv
        response['Content-Disposition'] = 'attachment; filename="{}"'.format("filename.csv")
        wr = csv.writer(response, dialect='excel')
        # get queryset
        queryset = Musician.objects.all()
        # write every queryset to response object
        for obj in queryset:
            row = [obj.first_name, obj.last_name, obj.instrument]
            wr.writerow(row)
        # return response object
        return response
