有类似的问题，我想出了自定义小部件加上模型形式的一些调整。这是小部件：

I had similar problem and I came up with custom widget plus some tweaks to model form. Here is the widget:

from django.utils.safestring import  mark_safe    

class ModelLinkWidget(forms.Widget):
    def __init__(self, obj, attrs=None):
        self.object = obj
        super(ModelLinkWidget, self).__init__(attrs)

    def render(self, name, value, attrs=None):
        if self.object.pk:
            return mark_safe(
                u'<a target="_blank" href="../../../%s/%s/%s/">%s</a>' %\
                      (
                       self.object._meta.app_label,
                       self.object._meta.object_name.lower(),
                       self.object.pk, self.object
                       )
            )
        else:
            return mark_safe(u'')

现在，由于每个内联的widget都需要在构造函数中获取不同的对象，所以不能只是在标准的方式，但在Form的 init 方法：

Now since widget for each inline need to get different object in constructor you can't just set it in standard way, but in Form's init method:

class TheForm(forms.ModelForm):
    ...
    # required=False is essential cause we don't
    # render input tag so there will be no value submitted.
    link = forms.CharField(label='link', required=False)

    def __init__(self, *args, **kwargs):
        super(TheForm, self).__init__(*args, **kwargs)
        # instance is always available, it just does or doesn't have pk.
        self.fields['link'].widget = ModelLinkWidget(self.instance)

我希望有帮助。
