How do I import data using Django-Import-Export? - django

Question

The documentation for django-import-export is a bit weak on how to configure the admin to import from a spreadsheet. Does anyone have a full example?

Answer 1

This is not a fully complete module. But you can understand how it should be.
resources.py file
from import_export import resources
from .models import edxUser
class edxUserResource(resources.ModelResource):
class Meta:
model = edxUser
#skip_unchanged = True
#report_skipped = True
#if you want to exclude any field from exporting
exclude = ('id','edx_anonymized_id')
fields = ('id', 'edx_id', 'edx_anonymized_id', 'edx_email', 'edx_name', 'time_created', 'created_by')
#Order of the export fields
export_order = ('edx_id', 'edx_email')
admin.py file
from import_export.admin import ImportExportModelAdmin
from django.contrib import admin
from .models import edxUser
from resources import edxUserResource
#admin.register(edxUser)
class edxUserAdmin(ImportExportModelAdmin):
resource_class = edxUserResource
models.py file
from __future__ import unicode_literals
from django.conf import settings
from django.db import models
class edxUser(models.Model):
edx_id = models.IntegerField('edX user id', blank=True, null=True)
edx_anonymized_id = models.IntegerField("edX anonymized user id", blank=True, null=True)
edx_email = models.EmailField('edx user email', max_length=75, blank=True)
edx_name = models.CharField('edx name', max_length=75, blank=True, null=True)
time_created = models.DateField('Created time', blank=True, null=True)
created_by = models.OneToOneField(settings.AUTH_USER_MODEL, null=True, blank=True)
def __unicode__(self):
return str(self.edx_id)

Here's how to do it, assuming that the column names in the spreadsheet are Title and Field one. This example assumes that the model instances will be created afresh every import (rather than being updated via a primary key).
from django.contrib import admin
from import_export.admin import ImportMixin
from import_export import resources, fields
from .models import MyModel
class MyModelResource(resources.ModelResource):
title = fields.Field(attribute='title',
column_name='Title')
field_one = fields.Field(attribute='field_one',
column_name='Field one')
def get_instance(self, instance_loader, row):
# Returning False prevents us from looking in the
# database for rows that already exist
return False
class Meta:
model = MyModel
fields = ('title', 'field_one')
export_order = fields
class MyModelAdmin(ImportMixin, admin.ModelAdmin):
resource_class = MyModelResource
admin.site.register(MyModel, MyModelAdmin)
