Rails Return multiple content_tags from Helper module

问题:

I've written the following helper:

def section_to_html (block)       case block[0].downcase       when "paragraph"         block.shift         block.each do |value|           return content_tag(:p, value)         end       end   end 

It is currently parsed these arrays.

["paragraph", "This is the first paragraph."] ["paragraph", "This is the second.", "And here's an extra paragraph."] 

And it returns:

<p>This is the first paragraph.</p> <p>This is the second.</p> 

Is there a way to accumulate the content_tag? so it returns:

<p>This is the first paragraph.</p> <p>This is the second.</p> <p>And here's an extra paragraph.</p> 

My only solution right now is to use a partial instead. But that's going to get very messy once I starting adding more to case condition.

Use #concat:
