Question

我在下面的django中创建了模型：

模型

class TermPolicyPeriod(models.Model):
    term = models.IntegerField()
    start_term = models.DateField(auto_now_add=False, blank=True, null=True)
    end_term = models.DateField(auto_now_add=False, blank=True, null=True)
    term_end = models.BooleanField(default=False)

class TermPolicyDetails(models.Model):
    branch = models.CharField(max_length=150)
    branch_code = models.CharField(max_length=3)
    class_type = models.CharField(max_length=255)
    week_type = models.CharField(max_length=10)
    students_per_coach = models.IntegerField()
    start_class_time = models.TimeField(auto_now_add=False, blank=True)
    end_class_time = models.TimeField(auto_now_add=False, blank=True)
    duration_class_time = models.TimeField(auto_now_add=False, blank=True)
    notes = models.TextField(max_length=350, null=True)
    foreign_key_term_end = models.ForeignKey(TermPolicyPeriod, on_delete=models.CASCADE)

...
args = {
        # Term Policies - Period
        'new_term_policy_period_form': new_term_policy_period_form,
        'term_period_policy_page_data': term_period_policy_page_data,
        'edited_tpp': edited_tpp,
        # Term Policies - Details
        'new_term_policy_details_form': new_term_policy_details_form,
        'term_policy_details_page_data': term_policy_details_page_data,
        'edited_tpd': edited_tpd,
    }
    return render(request, 'static/html/home.html', args)

在我要在html中创建的表单中，我希望foreign key自动链接到TermPolicyPeriod pk。我一直在搜索，但是不确定syntax应该如何写。我想到了

<form> 
{% csrf_token %}
{% for pp in new_term_policy_period_form %}
    {% for pd in new_term_policy_details_form %}
        {% set pd.foreign_key_term_end_id = pp.pk %}
    {% endfor %}
{% endfor %}

...
<button type="submit">submit</button>
</form>

在html中是否可能出现这种情况？

为了正确设置外键，您应该在视图中的TermPolicyPeriod中创建新的form.is_valid()实例，然后将TermPolicyDetails的外键设置为该实例的pk。

如何自动在html
