如何使用 DJANGO 表格将记录编辑到模板中

Question

我有两个相互关联的模型，分别是 child 和 academy 模型，这意味着孩子可以有学术详细信息，然后我将孩子 ID 传递到模板中以编辑孩子的学术详细信息

这是学院模型

#ACADEMY MODEL
from child.models import Child_detail
class Academic(models.Model):
    Student_name = models.ForeignKey(Child_detail,on_delete = models.CASCADE)
    Average_grade = models.CharField(max_length = 10)
    Overall_position = models.IntegerField()
    Total_number_in_class = models.IntegerField()
    def __str__(self):
        return str(self.Student_name)

这是子模型

#CHILD MODEL
from django.db import models

class Child_detail(models.Model):
    Firstname = models.CharField(max_length = 50)
    Lastname = models.CharField(max_length = 50)
    Tribe = models.CharField(max_length = 50)
    Current_Address = models.CharField(max_length = 50)

    def __str__(self):
        return self.Firstname

我想通过使用 django 表单到我传递孩子 ID 的模板来编辑孩子的学术详细信息

def edit(request,pk):
    child=get_object_or_404(Child_detail,pk=pk)
    form=AcademicForm(request.POST or None,instance=child)
    if form.is_valid():
        form.instance.Student_name=child
        form.save()
        return redirect('more',pk=pk)
    context={
        'form':form
    }
    return render(request,'functionality/more/academy/edit.html',context)    

这是我的 form.py 文件

class AcademicForm(forms.ModelForm):
    class Meta:
        model=Academic
        fields='Class','Date','Average_grade','Overall_position','Total_number_in_class'
        labels={
            'Average_grade':'Average Grade',
            'Overall_position':'Overall Position',
            'Total_number_in_class':'Total Number In Class'
        }

    Date = forms.DateField(
    widget=forms.TextInput(     
        attrs={'type': 'date'} 
    )
        )

这也是我传递子 ID 的模板

            <form action="" method="post" autocomplete="on">
            {% csrf_token %}
            <div class="form-group">
              {{form}}
              <input type="submit" value="Save" class="btn btn-primary btn-block">
            </form>

Answer 1

表单验证后

if form.is_valid(): 
      form.Student_name=child
      form.save()
