python - Django 模型保存

Question

我如何使用模型中的函数处理薪水并将其保存到 year_salary

示例模型:

class Staff(models.Model):
    salary = models.FloatField()
    year_salary = ArrayField(models.FloatField()

和函数:

def function(salary):
    year_salary = salary * 12
    return year_salary

Answer 1

据我了解，您想存储一系列年薪？

class Staff(models.Model):
    salary = models.FloatField()
    year_salary = ArrayField(models.FloatField())

    def calculate_year_salary(self):
        return self.salary * 12    

    def save(self, *args, **kwargs):
        if not self.year_salary:
            self.year_salary = [self.calculate_year_salary()]
        else:
            self.year_salary.append(self.calculate_year_salary())
        super(Staff, self).save(*args, **kwargs)
