Question

我有一个非常简单的模型来选择以我的语言显示一周中的几天，就像这样：

class Day(models.Model):
DAY_OF_WEEK = (
    ('Monday', 'Poniedziałek'),
    ('Tuesday', 'Wtorek'),
    ('Wednesday', 'Środa'),
    ('Thursday', 'Czwartek'),
    ('Friday', 'Piątek'),
    ('Saturday', 'Sobota'),
    ('Saturday', 'Niedziela')
)
    day_week = models.CharField(max_length=15, choices=DAY_OF_WEEK, default=date.today)

如何在表单中自动将字段设置为星期几？根据我的期望（default=date.today），将其添加到模型中无法正常工作。任何帮助将不胜感激。

尝试一下。定义一个函数以获取week_day

的默认值

def get_default():
    week_day = date.today().weekday()
    if week_day == 0:
        return "Monday"
    if week_day == 1:
        return "Tuesday"
    if week_day == 2:
        return "Wednesday"
    if week_day == 3:
        return "Thursday"
    if week_day == 4:
        return "Friday"
    if week_day == 5:
        return "Saturday"
    if week_day == 6:
        return "Sunday"



class Day(models.Model):
#####################
# model fields....
#####################

    week_day = models.CharField(max_length=15, default=get_default)

自动在models.py中添加CharField的星期几
