包含外键字段的 Django 模型表单

Question

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“运动员”，然后是字段名称。这似乎不起作用。

我尝试过使用 ModelChoiceField 的查询集，但我认为我没有正确设置。

提前感谢您的帮助。

这是主要模型（ASP 预订），包括外键运动员

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')

运动员模特

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, null=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, null=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，我需要表单来显示以下字段。 asp_booking_ref、program_type、运动员 id、运动员姓名。）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'}),
            
    }
