Question

我正在尝试保存用户在数据库中选择的选项（选项），并使用数据库中保存的数据填充（选中/选择）相同的选项。

型号：

class ScheduledEvent(models.Model):

event_id            = models.IntegerField()
project_id          = models.ForeignKey(Project, db_column = 'project_id')
start_date          = models.DateTimeField(null = False, default = timezone.now)
end_date            = models.DateTimeField(null = False, default = timezone.now)
next_scheduled_date = models.DateTimeField(default = timezone.now)
include_week_day    = models.CharField(max_length=200)
include_month_day   = models.CharField(max_length=200)

剩下的代码：

weekdays=(('Mon',"Monday"),
        ('Tue','Tuesday'),
        ('Wed','Wednesday'),
        ('Thr','Thrusday'),
        ('Fri','Friday'),
        ('Sat','Saturday'),
        ('Sun','Sunday'))


class CheckBoxdays(forms.ModelForm):
    model = ScheduledEvent
    included_week_day = forms.MultipleChoiceField(choices=weekdays, widget=forms.CheckboxSelectMultiple)

选项将保存在数据库中，但选项（选项）不会从存储在数据库中的数据中填充。

但是以下代码可以正常工作：

weekdays=(('1',"Monday"),
        ('2','Tuesday'),
        ('3','Wednesday'),
        ('4','Thrusday'),
        ('5','Friday'),
        ('6','Saturday'),
        ('7','Sunday'))

class CheckBoxdays(forms.ModelForm):
    model = ScheduledEvent
    include_week_day = forms.MultipleChoiceField(choices=weekdays, widget=forms.CheckboxSelectMultiple)

当选择元组中的第一个值是单个字符时，将填充选项。我在这里做错了吗？

您必须使用MultipleChoiceFile的Model版本来执行您想要执行的操作：

class CheckBoxdays(forms.ModelForm):
    model = ScheduledEvent
    include_week_day = forms.ModelMultipleChoiceField(choices=weekdays, widget=forms.CheckboxSelectMultiple)

Django：无法使用带有CheckboxSelectMultiple的MultipleChoiceField填充复选框
