Answer 1

Seems "django-import-export" still using the default one 'id'. for the time been, included a column 'id' in the header in CSV file and excluded importing in resources.py

class edxUserResource(resources.ModelResource):

    class Meta:
        model = edxUser
        skip_unchanged = True
        report_skipped = True
        exclude = ('id',)
        import_id_fields = ('edx_id', 'edx_email', 'edx_name',)
        #export_order = ('edx_id', 'edx_email')

Answer 2

The id field is an auto increment field, so if you're adding new records (I believe its the most case) the id field should be there in the header (first line of csv file) and the rest of the rows should contain empty id like : ,

Example:

CSV File:
id, username,email,password
,ahmad,ahmad@all.com,secretum
,salafi,salafi@gmail.com,Passhdjdj

In the Resource file (py):
class JasResult(ImportExportModelAdmin):
    resource_class = JasResource
    skip_unchanged = True
    report_skipped = True
    exclude = ('id',)
    import_id_fields = ('username','email','password')

This should fine for most cases.

Answer 3

i have figure out the solution to import without ID column Here is code , Take a Look

    if request.method == 'POST':
    queryset = Client.objects.filter(company=company)
    company = Company.objects.get(id=company)
    person_resource = ClientResource()
    dataset = Dataset()
    new_persons = request.FILES['myfile']
    imported_data = dataset.load(new_persons.read().decode('utf-8'), format='csv')
    try:
        for row in dataset:
            client = Client()
            client.company = company
            client.title = row[0]
            client.first_name = row[1]
            client.last_name = row[2]
            client.email = row[3]
            client.position = row[4]
            client.company_name = row[5]
            client.vat_number = row[6]
            client.website = row[7]
            client.address = row[8]
            client.city = row[9]
            client.state = row[10]
            client.zip = row[11]
            client.country = row[12]
            client.phone = row[13]
            client.fax = row[14]
            client.notes = row[15]
            client.save()

    except Client.DoesNotExist:
        raise Http404("There is a Problem with The CSV")

return render(request, 'import.html')

And my Resource Looks Like this

class ClientResource(resources.ModelResource):
company = fields.Field(
    column_name='company',
    attribute='company',
    widget=ForeignKeyWidget(Company, 'name'))

class Meta:
    model = Client
    skip_unchanged = True
    report_skipped = True
    exclude = ('id', 'company', 'status', 'modified', 'created')
    import_id_fields = ['email']
