Play! + Scala: Split string by commnas then Foreach loop

Question

I have a long string similar to this:

"tag1, tag2, tag3, tag4"

Now in my play template I would like to create a foreach loop like this:

@posts.foreach { post =>
    @for(tag <- @post.tags.split(",")) {
        <span>@tag</span>
    }
}

With this, I'm getting this error: ')' expected but '}' found.

I switched ) for a } & it just throws back more errors.

How would I do this in Play! using Scala?

Thx in advance

Answer 1

Posting this because the answer marked correct isn't necessarily true, as pointed out in my comment. There are only two things wrong with the original code. One, the foreach returns Unit , so it has no output. The code should actually run, but nothing would get printed to the page. Two, you don't need the magic @ symbol within @for(...) .

This will work:

@for(post <- posts)
    @for(tag <- post.tags.split(",")) {
        <span>@tag</span>
    }
}

There is in fact nothing wrong with using other functions in play templates.

Answer 2

This should be the problem

@for(tag <- post.tags.split(",")) {
    <span>@tag</span>
}
