html - Rails nested list with concat content_tag in Helper -

-

i'm trying create similar this: using helpers in rails 3 output html

here's helper:

def section_references_to_html (section)      concat content_tag (:ol, :class => 'sources')         section.references.each |reference|           concat content_tag (:li,content_tag(:a, reference.text, :src => reference.url))         end       end   end

but it's returning sorts of syntax errors:

/~/app/helpers/application_helper.rb:21: syntax error, unexpected ',', expecting ')'      concat content_tag (:ol, :class => 'sources')                              ^ /~/app/helpers/application_helper.rb:21: syntax error, unexpected ')', expecting keyword_end      concat content_tag (:ol, :class => 'sources')                                                   ^ /~/app/helpers/application_helper.rb:22: syntax error, unexpected keyword_do_block, expecting keyword_end         section.references.each |reference|                                   ^ /~/app/helpers/application_helper.rb:23: syntax error, unexpected tidentifier, expecting keyword_do or '{' or '('           concat content_tag (:li,content_tag(:a, referen...                             ^ /~/app/helpers/application_helper.rb:23: syntax error, unexpected ',', expecting ')' ...       concat content_tag (:li,content_tag(:a, reference.tex... ...                               ^ /~/app/helpers/application_helper.rb:23: syntax error, unexpected ')', expecting keyword_end

what doing wrong here? maybe using partial better.

the main problem have spaces between content_tag , (. try this:

def section_references_to_html(section)   content_tag(:ol, class: 'sources')     section.references.each |reference|       content_tag(:li, content_tag(:a, reference.text, href: reference.url))     end   end end
