Create a link.button with icon

button_link('Blog', '/blog', :icon => 'blog_image.png') #=> <a href="/blog" class="button"><img src="/images/blog_image.png" alt="Blog" /> Blog</a>

def button_link(txt, path, attrs = {}, incl_span = false)
  image   = attrs.delete(:icon)
  klasses = (attrs.delete(:class) || "").split(" ")
  klasses << 'button'
  klasses  = klasses.uniq.compact        
  content  = ""
  content <<  image_tag(image) unless image.nil?
  content << (incl_span ? "<span>#{txt}</span>" : txt)
  link_to content.html_safe, path, attrs.merge(:class => klasses.join(" "))
end

#flash_messages(attrs = {}) ⇒ Object

Convenience method for outputting all current flash messages. This allows you to avoid using things like “if flash” and so on, which is far from DRY

Examples:

Output any available flash messages, appending a “closer” span

In your controller:
  flash[:success] = "You did something awesome"
In your view or layout
<%= flash_messages :close => "<span>X</span>" %> #=> <div class="flash_message flash_message_success success">You did something awesome <span>X</span></div>

Output a message without a “close”

<%= flash_messages :close => false %> #=> <div class="flash_message flash_message_success success">You did something awesome</div>

Parameters:

  • attrs (Hash) (defaults to: {}) —

    Options to modify the html attributes and settings

Options Hash (attrs):

  • closer (Symbol) —

    Specify HTML to be appended to the message in case you want a “close” button/link. Defaults to “<span>X</span>”

  • wrapper (Symbol) —

    Specify the HTML element which wraps each message. Defaults to :div
