如何用模型对象数据填写表格? [英] How can I fill up form with model object data?

问题描述

我想用模型实例中的数据填写表格.但是我的表单域比模型域少.如果我有这样的代码:

I want to fill up form with data from model instance. But my form has less fields than model. If I have code like this:

class Item(models.Model)
    name = models.CharField(max_length=100)
    price = models.PositiveIntegerField()

class ItemForm(forms.Form):
    name = forms.CharField()

此功能有什么问题，看起来应该如何?

What wrong is with this function and how it should look to be good?

def bound_form(request, id):
    item = Item.objects.get(id=id)
    form = ItemForm(item.name)
    return render_to_response('bounded_form.html', {'form': form})

我收到这样的错误:AttributeError: 'ItemForm' object has no attribute 'get'

推荐答案

def bound_form(request, id): 
    item = Item.objects.get(id=id) 
    form = ItemForm(initial={'name': item.name}) 
    return render_to_response('bounded_form.html', {'form': form})
