Put a link in a flash[:notice]

Question

I am learning Ruby and Rails.

I have a Ruby on Rails project that tracks jobs a server is running. Right now, when I manually create a new job, it announces:

<

Answer 1

Building on Dorian's answer, here's an internationalized flash with a link in it:

flash[:notice] = t('success', go: view_context.link_to(t('product'), @product)).html_safe

Where your translation (e.g. a YAML file) might contain:

en:
  success: "Successfully created a %{go}"
  product: "product"
it:
  success: "%{go} creato con successo"
  product: "Prodotto"

Answer 2

The selected answer didn't work for me. But the answer from this post worked. I'm using Rails 4.2.4 by the way. With guidance from the answer I linked, here's how I did it:

View

<% flash.each do |name, msg| %>
  <div class="alert alert-<%= name %>">
    <button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>
    <div id="flash_<%= name %>"><%= sanitize(msg) %></div>
  </div>
<% end %>

Controller

flash[:success] = "Blah blah. #{view_context.link_to('Click this link', '/url/here')}"

The magic is the sanitize method.

I didn't need to use .html_safe as well.

You can always use the Rails link_to helper:

flash[:notice] = "Created job job number #{link_to update.id, :controller => 'jobs', :action => 'list', :job => update.id}."

Answer 4

Don't forget to add .html_safe at the end of the notice, if you're using Rails3. So it would say flash[:notice] = "Your message".html_safe

Answer 5

You can use an alias in your controller to the link_to function, or the RailsCast recipe:

"Created job job number #{@template.link_to update.id, 
  :controller => 'jobs', :action => 'list', :job => update.id}."

Answer 6

As nas commented, link_to is not available from your controller unless you include the appropriate helper module, but url_for is. Therefore I'd do pretty much what Emily said except use url_for instead of hardcoding a URL.

e.g. if a job were defined as a resource in your routes:

link = "<a href=\"#{url_for(update)}\">#{update.id}</a>"    
flash[:notice] = "Created job number #{link}"
