One argument against using single quotes is that you will not be able to embed ruby code into your link: "<br />A link to a #{link_to("website", "http://ruby-forum.com")}" If you want consistency, consistently use double quotations. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Re: Forcing helper like link_to to use single quotes
Dear Friends, I am the original poster. I use double quote for all Ruby strings in my Ruby codes. But, I use single quotes for HTML attributes.

Sheesh, I don''t know... Smack yourself in the head every time you type a double-quote for an HTML attribute??? Use an IDE and re-write the syntax rules for the language recognition so it does not allow double-quotes for HTML attributes? Surely, there are more important things you could be learning in the time you are spending trying to force the code to be ''just so''. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Regardless of sharkie''s original intent, there''s a use case where forcing single quotes on an HTML attribute value, generated through a Rails helper, would be useful - namely attaching JSON to HTML elements via HTML 5 data attributes. In order for the JSON to be valid, it needs to be wrapped in single quotes so that double quotes can be utilized within the JSON itself, as required in the JSON spec. Given that single quotes on attribute values are permissible within the HTML spec, I see generating HTML through a Rails helper that uses single, rather than double, quotes as a reasonable request. Unfortunately, I have yet to figure out how. Any ideas would be greatly appreciated. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thanks for the response Marnen. Unfortunately, I don''t think
that''ll
work. Here''s, for instance, what the Webkit Javascript console returns
using the native JSON.parse method:
JSON.parse("{"test":100}");> SyntaxError: Unable to parse JSON string
JSON.parse("{''test'':100}");> SyntaxError: Unable to parse JSON string
JSON.parse(''{"test":100}'');> Object

I stand corrected. I was improperly escaping the quotes when I tested a
helper method the first time around. The JSON from my previous example
parses correctly when added like so:
"data-mydatakey" => "{\"test\":100}"
Marnen, sorry for jumping to conclusions and thanks for the help.
