Rails - acts_as_taggable_on Removes Commas When Editing

Question

I have successfully set up acts_as_taggable_on my model. As expected, when I split the tags with commas, it splits the tags correctly.

However, when I edit the post the field is auto populated with the tags for editing, except the commas are now gone.

This means if I hit save without putting them back in, the tags now become all one tag.

I have tried using ActsAsTaggableOn.delimiter = ' ' which works when they are one word tags. But now I have the issue that if i have a two word tag, when I edit and save the post the two word tags now become one word tags.

Any help anybody might have on this would be greatly appreciated.

Thanks!

Answer 1

This behavior is apparently by design in acts_as_taggable_on.

Try adding to_s to your tag_list in the form input:

<%= f.text_field :tag_list, value: @example_record.tag_list.to_s %>

Not ideal, but this should allow your field to display the comma separated tags properly.
