Ok, so I have this application where the users make an order for a Category through the app. Every category contains products. And what I want to do is when a product is issued to the user the order status for the order made by the user should change from 1(approved) to 4(issued) and the product name should be added in the order table to confirm the product that was issued to that request.
How do I do that in Django? Below are my models
class Category(models.Model):
name = models.CharField(max_length=50, blank=True, null=True)
timestamp = models.DateTimeField(auto_now_add=False, auto_now=True, null=True)
class Product(models.Model):
pro_name = models.CharField(max_length=100, blank=True, null=True)
category = models.ForeignKey(Category, on_delete=models.CASCADE, blank=True, null=True)
issue_to = models.ForeignKey('Order',default='', on_delete=models.CASCADE,blank=True, null=True)
serial_num = models.CharField(max_length=100, blank=True, null=True)
model_num = models.CharField(max_length=100, blank=True, null=True)
storage_size = models.CharField(max_length=50, blank=True, null=True)
memory_size = models.CharField(max_length=50, blank=True, null=True)
supplier = models.ForeignKey(Supplier, on_delete=models.CASCADE, blank=True, null=True)
receive_quantity = models.IntegerField(default='0', blank=True, null=True)
issue_quantity = models.IntegerField(default='0', blank=True, null=True)
issue_by = models.CharField(max_length=50, blank=True, null=True)
last_updated = models.DateTimeField(auto_now_add=False, auto_now=False, null=True)
timestamp = models.DateTimeField(auto_now_add=False, auto_now=True, null=True)
class Order(models.Model):
category = models.ForeignKey(Category, on_delete=models.CASCADE, null=True)
pro_name = models.ForeignKey(Product, on_delete=models.CASCADE, null=True,related_name='product')
staff = models.ForeignKey(User, on_delete=models.CASCADE, null=True)
order_quantity = models.PositiveIntegerField(null=True)
department = models.CharField(max_length=50, choices=DEPARTMENT, null=True)
order_status = models.IntegerField(default=0)
approve_quantity = models.IntegerField(default='1', blank=True, null=True)
transaction_id = models.CharField(default=uuid.uuid4().hex[:8].upper(), max_length=50, editable=False)
timestamp = models.DateTimeField(auto_now_add=False, auto_now=True, null=True)
Currently what I do is after a particular product has been issued to a user I have to go to the order table and change the order status to 4(issued) which is hectic especially when the orders are plenty.

I am thinking of creating a referral and reward app where a user will list his/her company with the product they have. A company can use referral program by product specific or just in whole(could not name it properly). For example, I have listed my company called ABC Company and I have a product like smartphone, smart Tvs, Laptops. I would like to market for my company by just saying refer me to 10 people and get something in return(this is non-product specific) or I should be able to market my specific product let's say when user goes to the abc phone XI and there will be refer this phone and get the same phone in return if you refer to more than 50 or if more than 10 then 10% discount etc. This is just an example to demonstrate my project.
For now I created the model for Company, Product(with nested category), referral. But I have no idea on how should i be able to keep the referral based on above example like product specific or based on full company.
Here is what I have done
class Product(models.Model):
"""

I have created a role model for Employee so that employee will be assigned to control
the overall app based on his/her role. I mean if the role of employee is given can_create_only, then the employee should be able to create inventory, orders, items etc and if employee is given can_create_edit_and_delete, then the employee would be like one of the admin and etc. For this I have designed the model as below but I want to know what is the best way to handle such and why?
Should I go with middleware or decorator way? Can anyone give me an example, please?
class Role(models.Model):
name = models.CharField(max_length=100, blank=False, null=False)
class Meta:
verbose_name = 'Role'
verbose_name_plural = 'Roles'
class Employee(models.Model):
office = models.ForeignKey(
OfficeSetup, blank=False, null=False, on_delete=models.CASCADE)
name = models.CharField(max_length=150, blank=False, null=False)
designation = models.ForeignKey(Designation, blank=False, null=False)
section = models.ForeignKey(DepartmentSetup, blank=True, null=True)
phone_number = models.CharField(max_length=150, blank=True, null=True)
mobile_number = models.CharField(max_length=150, blank=True, null=True)
email = models.EmailField(max_length=150, blank=False, null=False)
gender = models.CharField(
max_length=4, choices=GENDER, blank=True, null=True)
role = models.ForeignKey(Role, blank=True, null=True)
username = models.CharField(max_length=100, blank=False, null=False)
password = models.CharField(max_length=100, blank=False, null=False)
avatar = models.ImageField(
null=True, blank=True, upload_to=upload_employee_image_path)
class Meta:
verbose_name = 'Employee'
verbose_name_plural = 'Employees'
def __str__(self):
return self.name
When creating an employee by admin, the username, password and email, the admin provides will create a new user instance along with the employee
