I tried to display the Topic ID in the initial Post of all topics of a specific category but failed. I could not find a way by configuring Discourse and also a plugin - similar to Discourse BBCODE - failed to work.
Could you please give me a clear hint on how to realize to display the Topic ID in the initial Post metadata of each topic of a specific category?
I need this to continue the customer expectations of the old system as well some related functions and behavior.
Thanks a lot!
The topic_id is at the end of the URL.
Can you say more about what expectations you are tryingto may and what features you need?
As I mentioned in my Post I try to write a plugin, probably the Development category is not the proper place due I don’t want this in Discourse itself. Can you point me to some kind of solution how to display additional (existing) meta data in the initial Post Header?
I know that the URL contains the TopicID as last “Tuple” and there is also a canonical link in the html header that does. I need to display the TopicID on the initial Post. We often speak about “Topic#34074” or something and want to stay with that habit, which our customers and partners are used to.
So I tried to extract the ID (successfully) and past it into the ‘div.topic-meta-data’, which failed.
Add this to Settings > Customize > Common > </head>:
<script type="text/discourse-plugin" version="0.5">
api.decorateWidget('post-meta-data:after', dec => {
if (dec.attrs.post_number === 1) {
const topic = dec.getModel().get('topic');
return dec.rawHtml(`<div class="post-info topic-id">Topic: ${topic.get('id')}</div>`);
}
});
</script>
And you get:
And you just need to add some CSS.
of course, stylesheets are needed! 
exactly what I’m looking for - thanks a lot!!! 
Olá, o ID do tópico aparecerá após os metadados da postagem.
Quero que ele apareça após o título do tópico. Como faço isso?
Muito obrigado!
Você pode simplesmente fazer component-name:afterwidget-name:after. Ou use um plugin outlet se estiver disponível na posição desejada.
Não funcionou 
<script type="text/discourse-plugin" version="0.5">
api.decorateWidget('component-name:after', dec => {
if (dec.attrs.post_number === 1) {
const topic = dec.getModel().get('topic');
return dec.rawHtml(`<div class="post-info topic-id">Tópico: ${topic.get('id')}</div>`);
}
});
</script>
Você realmente colocou component-namewidget-name em vez do nome real do componente?
Olá, quem pode me ajudar
Você tentou o que o Falco sugeriu na postagem acima?
