inputs are not being stored in Mysql database - mysql

Question

i am currently having an issue with my program my some of my input are not being saved in the MySQL database - any help will be appreciated
this creates a custom user which are the employee, admin and senior employee - this is a different model so another table
class CustomUser(AbstractUser):
user_type_data=((1,"Admin"),(2,"senioremployee"),(3,"employee"))
user_type=models.CharField(default=1,choices=user_type_data,max_length=20)
this the model for one of my usertypes
class senioremployee(models.Model):
id = models.AutoField(primary_key=True)
admin=models.OneToOneField(CustomUser, on_delete=models.CASCADE)
Dob = models.DateField()
Nationality = models.TextField()
Address = models.TextField()
Postcode = models.TextField()
Telephone = models.TextField()
Wage = models.TextField()
Passportnumber = models.TextField()
passportexpirydate = models.DateField()
gender = models.CharField(max_length=255)
profile_pic = models.FileField()
kinname = models.TextField()
kinrelation = models.TextField()
kinaddress = models.TextField()
kinphonenumber = models.TextField()
kinemail = models.TextField()
created_at=models.DateTimeField(auto_now_add=True)
updated_at=models.DateTimeField(auto_now_add=True)
objects = models.Manager()
this function add user's data to the table
#receiver(post_save,sender = CustomUser)
def create_user_profile(sender,instance,created,**kwargs):
if created:
if instance.user_type==1:
admin.objects.create(admin = instance,Dob="",Nationality="",Address="",Postcode="",Telephone="",Wage="",Passportnumber="",passportexpirydate="",gender="",profile_pic="",kinname="",kinrelation="",kinaddress="",kinphonenumber="",kinemail = "")
if instance.user_type==2:
senioremployee.objects.create(admin = instance,Dob="",Nationality="",Address="",Postcode="",Telephone="",Wage="",Passportnumber="",passportexpirydate="",gender="",profile_pic="",kinname="",kinrelation="",kinaddress="",kinphonenumber="",kinemail = "")
if instance.user_type==3:
employee.objects.create(admin = instance,Dob="",Nationality="",Address="",Postcode="",Telephone="",Wage="",Passportnumber="",passportexpirydate="",gender="",profile_pic="",kinname="",kinrelation="",kinaddress="",kinphonenumber="",kinemail = "")
this is the function that is meant to save the inputs into the senioremployee's table and email,password , firstname, lastname,username into the custom user's table but currently it only stores email,password , firstname, lastname,username into the custom user's table and just ignores the other user inputs
def add_seniorEmployee_save(request):
if request.method!="POST":
return HttpResponse("Method Not Allowed")
else:
first_name=request.POST.get("first_name")
last_name=request.POST.get("last_name")
username=request.POST.get("username")
email=request.POST.get("email")
password=request.POST.get("password")
Dob=request.POST.get("Dob")
Nationality=request.POST.get("Nationality")
Address=request.POST.get("Address")
Postcode=request.POST.get("Postcode")
Telephone=request.POST.get("Telephone")
Wage=request.POST.get("Wage")
Passportnumber=request.POST.get("Passportnumber")
passportexpirydate=request.POST.get("passportexpirydate")
gender=request.POST.get("gender")
kinname=request.POST.get("kinname")
kinrelation=request.POST.get("kinrelation")
kinaddress=request.POST.get("kinaddress")
kinphonenumber=request.POST.get("kinphonenumber")
kinemail=request.POST.get("kinemail")
try:
user = CustomUser.objects.create_user(username=username,password=password,email=email,first_name=first_name,last_name=last_name,user_type=2)
user.senioremployee.Dob = Dob
user.senioremployee.Nationality = Nationality
user.senioremployee.Address = Address
user.senioremployee.Postcode = Postcode
user.senioremployee.Telephone = Telephone
user.senioremployee.Wage = Wage
user.senioremployee.Passportnumber = Passportnumber
user.senioremployee.passportexpirydate = passportexpirydate
user.senioremployee.gender = gender
user.senioremployee.profile_pic=""
user.senioremployee.kinname = kinname
user.senioremployee.kinrelation = kinrelation
user.senioremployee.kinaddress = kinaddress
user.senioremployee.kinphonenumber = kinphonenumber
user.senioremployee.kinemail = kinemail
user.save()
messages.success(request, "Successfully Added Senior Employee")
return HttpResponseRedirect("/add_seniorEmployee")
except:
messages.error(request, "Couldnt add senior employee")
return HttpResponseRedirect("/add_seniorEmployee")

Answer 1

First you have a problem with your senioremployee creation query. You are using Dob and passportexpirydate as DateField.
class senioremployee(models.Model):
Dob = models.DateField()
passportexpirydate = models.DateField()
But when you are creating senioremployee record you are passing empty string which eventually produce exception.
post_save signal
try:
senioremployee.objects.create(admin = instance,Dob="",Nationality="",Address="",Postcode="",Telephone="",Wage="",Passportnumber="",passportexpirydate="",gender="",profile_pic="",kinname="",kinrelation="",kinaddress="",kinphonenumber="",kinemail = "")
except Exception as e:
print("e)
It will return the exception
['“” value has an invalid date format. It must be in YYYY-MM-DD format.']
so pass YYYY-MM-DD date format to Dob and passportexpirydate then senioremployee will be created.
When you are updating record, you are saving user model again which again raise post_save signal and you will be creating duplicate senioremployee record which return UNIQUE constraint failed.
So you must use this line of code to update senioremployee record
user.senioremployee.save()
instead of
user.save()
