This isn’t working…
```plaintext
client.create_topic(
title: "My Title",
category: "13",
raw: "My Post",
tags: "testtag"
)
```
Since we require at last one tag, I get:
```plaintext
DiscourseApi::UnprocessableEntity ({"action"=>"create_post", "errors"=>["You must select at least 1 tag."]}):
```
Any idea how we create topics with tags via the Discourse gem?

Maybe make it `tags:["testtag"]`

That doesn’t work either Faizaan (same message that a tag is required).
Not sure if this is out of date, but it seems that tags are different to the others being some sort of array type - but how do we use that via the gem?

If you look at the network tab while making a successful request, then you can translate it to how to do it with the gem.

It needs this format:

But how to do that with the gem?

This is what I illustrated in my above post.

…but it does not work:

😕

Can you try some other tags?

Haha that’s what I was thinking too so just did - the last few I tried definitely exist (but still doesn’t work).

Can you turn off required tags on a category to see whether the thing actually works?

Do you mean the gem? It works as I use it to make posts in existing topics (from the same script in fact), send PMs etc. This is the first time I am trying to add tags though..

Ok, I see. I’m sure you are doing but just confirming
```plaintext
client.create_topic(
title: "My Title",
category: "13",
raw: "My Post",
tags: ["testtag", "testtag2"]
)
```

Looking at the source code for the discourse\_api gem it doesn’t look like it supports creating topics with tags yet. I’ll add it to my list.

Okay, you can create Topics with tags now using the latest version (0.42.0) of the discourse\_api gem.
You just need to pass the tags in an array like so:

Wow - that was fast Blake!
I wasn’t expecting an update so soon and so managed to find a workaround by using the post method and passing everything as params. Doing it with create\_topic is definitely better tho, thanks!
