我翻阅了类似的问题，但无法找到合适的解决方案，或者我错过了什么？我有两个模型（SafetyCourse和SafetyCourseTaken），我有一个外键关系，从 "已选安全课程 "指向安全课程，如下所示。
models.py
class SafetyCourse(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
name = models.CharField(max_length=128, unique=True)
def __str__(self):
return self.name
class SafetyCoursesTaken(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
profile = models.ForeignKey(EmployeeProfile, on_delete=models.CASCADE)
course = models.ForeignKey(SafetyCourse, on_delete=models.CASCADE, related_name='course_name')
conducted_date = models.DateTimeField(null=True, blank=True)
expiration_date = models.DateTimeField(null=True, blank=True)
class Meta:
verbose_name_plural = 'Safety Courses Taken'
views.py
class ManageSafetyCourseTakenView(LoginRequiredMixin, generic.ListView):
login_url = reverse_lazy('users:login')
model = SafetyCoursesTaken
template_name = 'ppm/courses-taken.html'
paginate_by = 10
# override get_queryset to only show training related to employee profile
def get_queryset(self):
pk = self.kwargs['pk']
return SafetyCoursesTaken.objects.filter(profile_id=pk)
课程学习.html(模板)
{% for course_taken in object_list %}
<td>{{ course_taken.course_id}}</td>
{% endfor %}
我已经尝试了很多类似问题的解决方案，但无法找到一个正确的方案。我试过：course_taken.course_name_set.select_related，course_taken.course_name_set，以及其他一些。我想做的是只显示课程的名称而不是课程ID。我做错了什么？
