Help with link_to_if, I can't make it work

Rails
1

For the life of me I can’t get it to work. Here is an example of my
syntax. I’m trying to make comment.name a link to comment.web_site only
if there is a comment.web_site. Can someone please help?

<%= link_to_if(comment.web_site.length > 0, comment.name,
comment.web_site {“class” => “comment_by”}) %>

has anyone else tried to use link_to_if?

ActionView::TemplateError (compile error
script/…/config/…/app/views/journal/view.rhtml:21: syntax error
comment.web_site {“class” => “comment_by”}) ).to_s); _erbout.concat
“\r\n”
^) on line #21 of
app/views/journal/view.rhtml:
18: commented…

19:

<%=
strip_tags(comment.comment) %>


20: <%= link_to_if(comment.web_site.length > 0,
comment.name,
21: comment.web_site {“class” => “comment_by”}) %>
22: <% end %>

Comment Form

Well, it seems like you’ve forgotten a comma.

Try:

<%= link_to_if(comment.web_site.length > 0, comment.name,
comment.web_site ----->,<------ {“class” =>
“comment_by”}) %>
