[英]How to loop over custom plugin data on the template in django cms 3.5.3
I am trying to implement a website that uses RSS Feeds. 我正在尝试建立一个使用RSS源的网站。 My use case is to be able to display one RSS feed at a time, then loop over to the next maybe after 5 seconds.
我的用例是一次可以显示一个RSS feed,然后可能在5秒钟后循环到下一个。 These RSS feeds need to be displayed on the same placeholder.
这些RSS feed必须显示在同一占位符上。 I am new to django cms in case you need more info please let me know.
如果您需要更多信息,我是django cms的新手,请告诉我。
I have googled a lot but all I can see is how to add plugins from the frontend and they will all automatically show inside the placeholder. 我已经在Google上搜索了很多,但是我所能看到的就是如何从前端添加插件,它们都会自动显示在占位符中。 Or modify the render method of the custom plugin class to display what you want.
或修改自定义插件类的render方法以显示所需内容。 But I want to display everything but one at a time in a continuous manner
但是我想一次连续地显示除一个以外的所有内容
@plugin_pool.register_plugin
class ExternalArticlePlugin(CMSPluginBase):
model = ExternalArticle
name = _("External article")
render_template = "external_article.html"
cache = False
def render(self, context, instance, placeholder):
context = super(ExternalArticlePlugin, self).render(
context, instance, placeholder
)
return context
I expect to display one RSS feed at a time inside my placeholder. 我希望在占位符中一次显示一个RSS feed。 Those feeds are links to the actual webpage with more info.
这些提要是指向实际网页的链接,其中包含更多信息。
one way would be to write a function random_rss_feed_url()
in ExternalArticle Model which renders a random rss instance. 一种方法是在ExternalArticle Model中编写一个函数
random_rss_feed_url()
,以渲染一个随机的rss实例。
model.py 模型
class ExternalArticle(models.Model):
def random_rss_feed_link(self):
return ExternalArticle.objects.order_by('?')[0].link
then you do in plugins external_article.html: 然后在插件external_article.html中进行操作:
{{ instance.random_rss_feed_link }}
Edited : 编辑 :
if you want to change automatically without page reload, then you need something like this in javascript in your template: 如果您想自动更改而无需重新加载页面,则您的模板中的javascript需要以下内容:
var rss_links = ['link_1', 'link_2', 'link_3'];
setInterval(function() {
// take random rss link
var random_link = rss_links[Math.floor(Math.random()*rss_links.length)];
// change the link
document.getElementById('rss_link_element').href = random_link;
}, 5000);
