我看了一下Stackoverflow上的其他解決方案，但似乎沒有任何幫助解決我遇到的問題。從表單中保存複選框值問題
我有一個表格來填寫需要保存的信息。我給用戶三個選項，他們可以打勾。但是，它不會保存表單，因爲它表示該值無效。
這裏是我的模型：
from django.db import models
from django.utils import timezone
FLAG_CHOICES = (('Active', 'Active'), ('Inactive', 'Inactive'),)
STATUS_CHOICES=(('Critical', 'Critical'), ('Medium', 'Medium'), ('Low','Low'))
class Event(models.Model):
event_status=models.CharField(max_length=10, choices=STATUS_CHOICES)
event_title=models.CharField(max_length=50)
event_description=models.CharField(max_length=500)
event_flag=models.CharField(max_length=10, choices=FLAG_CHOICES)
date_active=models.DateField(default=timezone.now())
time_active=models.TimeField(default=timezone.now())
def __str__(self):
return self.event_title
這裏是我的形式：
from django import forms
from server_status.models import Event
FLAG_CHECKBOX = [('active', 'Active'), ('inactive', 'Inactive'), ]
STATUS_CHOICES=[('critical', 'Critical'), ('medium', 'Medium'), ('low','Low'),]
class Add_Event_Form(forms.ModelForm):
event_title = forms.CharField(max_length=50, help_text="Please enter an informative title.")
event_status = forms.MultipleChoiceField(choices=STATUS_CHOICES, widget=forms.CheckboxSelectMultiple,
help_text="Please select the status of the event")
event_description = forms.CharField(max_length=500, initial="",
help_text="Enter a short description of the event here")
event_flag = forms.MultipleChoiceField(choices=FLAG_CHECKBOX, required=True, widget=forms.CheckboxSelectMultiple,
help_text="Please select the status of this event.")
date_active = forms.DateField(required=True, widget=forms.DateInput(attrs={'class': 'datepicker'}),
help_text="Please select a date for this event.")
time_active = forms.TimeField(required=True, widget=forms.TimeInput(format='%HH:%MM'),
help_text="Please select a time for this event in HH:MM format.")
class Meta:
model = Event
fields = '__all__' # I want all fields to be editable
在網頁本身這個錯誤顯示，當你按下保存：
Select a valid choice. [u'critical'] is not one of the available choices.
這個錯誤出現當你勾選「重要」框時，你就可以開始使用了。
