在django cms插件中上传多个图像

Question

我试图在django cms 3.6中创建一个自定义插件，其中有一个字段可以添加多个图像。为此我创建了两个模型并使用外键将其链接

model.py

我希望space_image字段为多张图片上传字段

class SpaceModel(CMSPlugin):
    space_name = models.CharField(max_length=50)
    space_size = models.CharField(max_length=50) 
    space_image =  models.FileField(upload_to="memox_images")


    def __unicode__(self):
        return "%s" % (self.space_name, )


class SpaceImages(models.Model):
    spacemodel = models.ForeignKey(SpaceModel, default=None)
    image = models.ImageField(upload_to='memox_images',
                              verbose_name='Image',blank="True",null="True",)
    def __unicode__(self):
        return "%s" % (self.spacemodel, )

views.py

class SpaceModelPlugin(CMSPluginBase):
    model = SpaceModel
    name = "New Space"
    render_template = "space_images.html"

    def render(self, context, instance, placeholder):
        context.update({
            'space_name' : instance.space_name,
            'space_size' : instance.space_size,
            'space_image':instance.space_image
        })
        return context

预先感谢
