如何解决在导航栏上打印用户模型属性
我正在尝试在导航栏上打印名字和公司名称，但没有打印出任何内容

is_active = models.BooleanField(default=True)
is_student = models.BooleanField(default=False)
is_employer = models.BooleanField(default=False)
objects = UserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
class Student(models.Model):
user = models.OneToOneField(User,on_delete=models.CASCADE,related_name='student_profile',primary_key=True)
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
gender = models.CharField(max_length=10,choices=GENDER_CHOICES)
level = models.CharField(max_length=3,choices=LEVEL)
school = models.CharField(max_length=5,choices=SCHOOL)
major = models.CharField(max_length=40,default="")
cv = models.FileField(blank=True)
skills_or_trainings = models.TextField(default="")
def __str__(self):
return self.first_name + ' ' + self.last_name
class Employer(models.Model):
user = models.OneToOneField(User,related_name='employer_profile',primary_key=True)
company_name = models.CharField(max_length=200,blank=False)
company_address = models.TextField()
website = models.CharField(unique=True,max_length=100,blank=False)
def __str__(self):
return self.company_name
form.py
class UserRegistrationForm(UserCreationForm):
class Meta:
model = User
fields = ['email']
def save(self,commit=True):
user = super().save(commit=False)
if commit:
user.save()
return user
class EmployeeRegistrationForm(forms.ModelForm):
first_name = forms.CharField(label='First Name')
last_name = forms.CharField(label='Last Name')
cv = forms.FileField(label='CV')
skills_or_trainings = forms.SlugField(label='Skills or Trainings',required=False,widget=forms.Textarea)
class Meta:
model = Student
fields = ['first_name','last_name','gender','level','school','major','cv','skills_or_trainings' ]
class EmployerRegistrationForm(forms.ModelForm):
company_name = forms.CharField(label="Company Name")
company_address = forms.CharField(label="Company Address")
website = forms.CharField()
class Meta:
model = Employer
fields = ['company_name','company_address','website']
我不知道我是否做对了，还是有其他方法可以调用导航栏中的模型字段。如果我使用{{user.email}}，它将打印出来，但是如果我使用{{student.first_name}}，它将不会打印出任何东西
解决方法
使用{{ user.student.first_name }}
