I came across an instance where I needed to add a link to flash notice tonight. Manually creating a hyperlink seems to work fine, however I was chasing a rubyish way of doing things:
flash[:notice] = "Order created - Click here to pay for it!"
Luckily a quick Google revealed the answer:
flash[:notice] = "Order created - Click here to pay for it!".html_safe
If you’re using rails 3 make sure you throw in the .html_safe or your link will be appear as plain text. Just a quick screenshot of the end result below:
Anyway, that’s all. Good Luck!
