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!!! 
Hola, el ID del tema se mostrará después de los metadatos de la publicación.
Quiero que se muestre después del título del tema, ¿cómo lo hago?
¡Muchas gracias!
Simplemente puedes hacer component-name:afterwidget-name:after. O utiliza un plugin outlet si está disponible en la posición que deseas.
No tiene efecto 
<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">Topic: ${topic.get('id')}</div>`);
}
});
</script>
¿Realmente escribiste component-namewidget-name en lugar del nombre real del componente?
Hola, ¿quién puede ayudarme ?
¿Probaste lo que Falco sugirió en el mensaje anterior?
