问题描述
我正在尝试在 Django 中创建一个模型表单，其中包含来自运动员表的外键字段。
通常在引用外键字段时，我可以使用字段名称“athlete”，然后是字段名称。这似乎不起作用。
我尝试使用 ModelChoiceField 使用查询集，但认为我没有正确设置。
在此先感谢您的帮助。
这是包括外键运动员的主要模型（ASP预订）
class ASPBookings(models.Model):
asp_booking_ref = models.CharField(max_length=10,default=1)
program_type = models.CharField(max_length=120,default='asp')
booking_date = models.DateField()
booking_time = models.CharField(max_length=10,choices=booking_times)
duration = models.CharField(max_length=10,choices=durations,default='0.5')
street = models.CharField(max_length=120)
suburb = models.CharField(max_length=120)
region = models.CharField(max_length=120,choices=regions,default='Metro')
post_code = models.CharField(max_length=40)
organisation_type = models.CharField(max_length=120,choices=organisation_types,default='Government School')
audience_number = models.CharField(max_length=10)
presentation_form = models.CharField(max_length=120,choices=presentation_form_options,default='Face to Face')
contact_name = models.CharField(max_length=80)
email = models.EmailField()
phone_number = models.CharField(max_length=120)
comments = models.TextField()
status = models.CharField(max_length=80,choices=statuses,default='TBC')
email_sent = models.BooleanField(default=False)
athlete = models.ForeignKey(Athlete,default= '1',on_delete=models.CASCADE)
def __str__(self):
return self.contact_name
# return URL after the POST has been submitted.
def get_absolute_url(self):
return reverse('vistours:success')
运动员模型
class Athlete(models.Model):
athlete_ref = models.CharField(max_length=10,default=1)
athlete_name = models.CharField(max_length=80)
email = models.EmailField()
phone_number = models.CharField(max_length=120)
home = models.CharField(max_length=120)
education = models.CharField(max_length=120)
sport = models.CharField(max_length=120,choices=sports,default='1500m Runner')
notes = models.TextField(default='None')
gender = models.CharField(max_length=120,choices=genders,default='Not Specified')
para_athlete = models.BooleanField(blank=True)
working_with_children = models.BooleanField(blank=True)
expiry_date = models.DateField(blank=True,null=True)
available = models.BooleanField(blank=True)
available_from = models.DateField(blank=True,null=True)
bfbw = models.BooleanField(blank=True)
latest_bfbw_session = models.DateField(blank=True,null=True)
number_bfbw_sessions = models.CharField(blank=True,null=True,max_length=10)
asp = models.BooleanField(blank=True)
latest_asp_session = models.DateField(blank=True,null=True)
number_asp_sessions = models.CharField(blank=True,max_length=10)
tours = models.BooleanField(blank=True)
latest_tours_session = models.DateField(blank=True,null=True)
number_tours_sessions = models.CharField(blank=True,max_length=10)
def __str__(self):
return self.athlete_name
# return URL after the POST has been submitted.
def get_absolute_url(self):
return reverse('home')
**下面是我尝试创建的表单，我需要该表单显示以下字段。 asp_booking_ref、program_type、athlete id、athlete_name。）我也尝试将这些显示为小部件，但在尝试添加时仅显示 asp_booking_ref 和 program_type 字段。
class ASPAssignAthleteForm(forms.ModelForm):
athlete = forms.ModelChoiceField(queryset=Athlete.objects.all())
class Meta():
model = ASPBookings
fields = '__all__'
widgets = {
'asp_booking_ref': TextInput(attrs={'id':'booking_id','name': 'booking_id'}),'program_type': TextInput(attrs={'id': 'program_type','name': 'program_type'}),}
