python - 如何让 django 表单向导 extra_context 显示在模板上？

Question

编辑: FWIW，我正在运行 django 1.3

我有...

class CreateProductWizard(FormWizard):
    def get_template(self, step):
        if step == 1:
            return 'product/form_wizard/editor.html'
        else:
            return 'product/form_wizard/wizard_%s.html' % step
    def process_step(self, request, form, step):
        if step == 1:
            self.extra_context = {'ptype': form.cleaned_data}
            return
        else:
            return
    def done(self, request, form_list):
        # now that it's all together, store it.
        return render_to_response('product/form_wizard/done.html',
            {'form_data': [form.cleaned_data for form in form_list]},
            context_instance=RequestContext(request))

我想将 self.extra_context 获取到模板中。

我如何在模板上获得它？

我试过模板:

{{extra_context}}
{{form.extra_context}}
{{form.extra_context.ptype}}

等..

查看 docs我会说 get_context_data是你所追求的:

Returns the template context for a step. You can overwrite this method to add more data for all or some steps. This method returns a dictionary containing the rendered form step.
