我对如何从后端模型检索数据并将其显示在我的网站上感到有点困惑。例如，我正在使用网站模型提供的拖放组件。如何在网站的轮播中显示自定义模型中的数据（例如图像）？此外，我想知道如何提交网站表单并将提交的数据插入我的自定义模型中。任何指导将不胜感激！
嗯，我正在尝试为用户创建一个完全定制的页面。
在您的自定义（覆盖）控制器中，您可以返回 request.render("a-model.view-key", data)，以便将自定义模型数据发送到网站模板“a-model.view-key”。 ..参见官网_博客插件为例：
website_blog/controllers/main.py
@http.route([
'''/blog/<model("blog.blog", "[('website_id', 'in', (False, current_website_id))]"):blog>/post/<model("blog.post", "[('blog_id','=',blog[0])]"):blog_post>''',
], type='http', auth="public", website=True)
def blog_post(self, blog, blog_post, tag_id=None, page=1, enable_editor=None, **post):
""" Prepare all values to display the blog.
:return dict values: values for the templates, containing
- 'blog_post': browse of the current post
- 'blog': browse of the current blog
- 'blogs': list of browse records of blogs
