CodePudding user response：

1. There is no need to create a custom function in Model, to fetch other values of other table which are in relation.

[ 1 ] you should have a related_name in your company user table. like

user = models.ForeignKey(
        settings.AUTH_USER_MODEL, models.DO_NOTHING, related_name='company')
# you can name company with something of your own choice.

# following will be more appropriate. 
user = models.ForeignKey(
        FutsalUser, models.DO_NOTHING, related_name='company')

[ 2 ] once you have a related_name, you can fetch the companies values as following.

FutsalUser.objects.all().values('email', 'is_active', 'company__name', 'company__hr_email')

2. Apart from that you can fetch the details from Company table instead.

Company.objects.all().values('name', 'user__email') # you can add more field if you want.

users = FatalUser.objects.all()
for user in users:
    company_list = user.company_details
    # this company_list will have the companies associated with user. 
    print(company_list)
    for company in company_list:
        print(company.name, company.hr_email)
