Re: [Rails-core] #asset_url helper method

[Rafael Mendonça França]

I think this is how all the assets helpers work by default.

Just putting this out there before I make a pull request.

Is there any interest in an asset_url method as a view helper?

It would work by using the config.action_controller.asset_host if it exists and prepending this to the results of asset_path.

I have found this necessary when writing html emails and needing a full url path for assets.  Since my CDN in the asset_host mirrors my assets in my app it makes perfect sense.  Might not be a common enough use case to put into core though.

I haven't had time to test but you're saying the asset_path helper will provide the full url by default?  

In console within production environment it seems to only return the path which isn't sufficient for html emails.

[Andrés Mejía]

If I remember correctly, asset_path will return the full URL if you set

config.action_mailer.asset_host = "http://my.assets.com"

in your environment file.
