Rails和HAML：Mailto与图片链接

Question

I am trying to create a mailto link that involves clicking a picture and including some raw content from a text file into the body of the message.

The following doesn't work (haml).

= mail_to "friend@example.com" do
  %img{:src=>"#{asset_path 'mail.png'}"}      

I don't even know how I'd get the body preloaded in there. I know there is a :body declaration but its usage in this context eludes me.

Thoughts?

The mail_to helper only appears to accept a block in Rails 4 , not previous versions . If you're using Rails 3 and can't upgrade, you could do something like this:

- mail_link_content = capture_haml do
  %img{:src=>asset_path('mail.png')} 

=mail_to "friend@example.com", mail_link_content

Note that you don't need to use a string if the contents are all interpolated (you might need to add parentheses though).

To get the body content, you just need to pass an options hash as the last argument to mail_to with a :body key:

Rails 4:

= mail_to "friend@example.com", :body => "Body text here" do
  %img{:src=>asset_path('mail.png')} 

Rails 3:

=mail_to "friend@example.com", mail_link_content, :body => "Body text here"
