how to convert array output to normal string in ruby on rails application

I am implementing tag functionality and an article may have one to many tags. I am able to get tag values from db in this format 

["social network", "professional"]

I want output in this format

"social network professional"

I want to convert an array into a string without ,. Below is a code snippet which takes out values from db as an array.

<%= article.tags.collect(&:name) %>

How can I convert this output into string value(s) with out any comma?

["social network", "professional"].join(",")

"social network,professional"

or if you don't want the comma

["social network", "professional"].join(" ")

"social network professional"

I got two solutions which are below:

<%= article.tags.collect(&:name).join(" ")%>
<%= article.tags.pluck(:name).join(" ") %> - by yossarian.

Did you look at pluck? This if very useful for if you want just one record from the db (in your case 'name'). You could use that to do this:

a = article.tags.pluck(:name)

To then output your article names separated by spaces do this:

a.join(" ")

For completeness sake, you can chain these methods (like you said in the comment below) like this:

article.tags.pluck(:name).join(" ")
