Python Django-如何动态填充formwizard表单'；从数据库中删除字段

第一个表单不是

表单集

，在第一步

项目

中很容易填充，但第二步是

表单集

。如何在

FormSet

中检索

Task

表单，并在向导步骤中使用表单及其各自的字段填充

FormSet

def get_form_initial(self, step):
    if 'project_id' in self.kwargs:
        if step == 'project':
            project_id = self.kwargs['project_id']
            project = Project.objects.get(pro_id=project_id)
            from django.forms.models import model_to_dict
            project_dict = model_to_dict(project)
            return project_dict
        elif step == 'task':
            project_id = self.kwargs['project_id']
            tasks = Task.objects.filter(project=project_id)
            print "tasks: %s " % tasks
            pp.pprint(self.__dict__)
            tasks_dict = model_to_dict(tasks)
            return tasks_dict
        else:
            print self.kwargs
    else:
        return self.initial_dict.get(step, {})
