this worked well, thanks!
Which version of Bootstrap is this for? I installed it on BS3 and it won't clear when the "X" is clicked.
Hi, I think there is an issue with Rails 4. May be caused for Turbolinks use?
Nice , it worked for me Rails 4. Thanks
Great ! It worked with rails4.
Great ! It worked with rails4.
Nice one, I've created another version of this here: https://gist.github.com/suryart/7418454
Great, fixed some problems with flash messages in ruby.railstutorial.org (with Rails 4 and las bootstrap). Thank you.
If you are using Bootstrap 3, the class names have been changed. Here is the new mapping:
module ApplicationHelper
def bootstrap_class_for flash_type
case flash_type
when :success
"alert-success" # Green
when :error
"alert-danger" # Red
when :alert
"alert-warning" # Yellow
when :notice
"alert-info" # Blue
else
flash_type.to_s
end
end
end
In file _messages.html.erb you can simply put
<% flash.each do |type, message| %>
<div class="alert <%= bootstrap_class_for(type) %> alert-dismissable fade in">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>
<%= message %>
</div>
<% end %>
does this work with GEM --- https://github.com/seyhunak/twitter-bootstrap-rails . I can't get success error message to show. any ideas?
RE: success message not working.... what is strange is the other 3 do work.
FYI - to get this to work, i also needed to add: add_flash_types :success, :info, :warning, :danger
to the applications controller.
As of 4.1 this code needs to be updated due to the :symbol to String change in flash messages.
def bootstrap_class_for(flash_type)
case flash_type
when "success"
"alert-success" # Green
when "error"
"alert-danger" # Red
when "alert"
"alert-warning" # Yellow
when "notice"
"alert-info" # Blue
else
flash_type.to_s
end
end
👍 @clarkbw, Thanks!! My flash helper method finally got working, because it did not work by :symbol to String issue.
def alert_class_for(flash_type)
{
:success => 'alert-success',
:error => 'alert-danger',
:alert => 'alert-warning',
:notice => 'alert-info'
}[flash_type.to_sym] || flash_type.to_s
end
Thanks for the great tip @annieogrady, that worked!
For Bootstrap 3:
<% flash.each do |type, message| %>
<div class="alert <%= alert_class_for(type) %> alert-dismissible fade in">
<button type="button" class="close" data-dismiss="alert"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<%= message %>
</div>
<% end %>
Thanks! This worked great for my Rails 4 app.

The code with the correct message shows up in the source but does not display on the screen.
Rails 4.1 my partial is always rendering with classes 'alert alert'. My testimonials_controller:
def update
respond_to do |format|
if @testimonial.update(testimonial_params)
format.html { redirect_to @Testimonial, success: 'Testimonial was successfully updated.' }
format.json { render :show, status: :ok, location: @Testimonial }
else
format.html { render :edit }
format.json { render json: @testimonial.errors, status: :unprocessable_entity }
end
end
end
Everything works fine with :alert, but not with any of the other names. The symbol doesn't seem to be getting recognised by the helper method.
fantastic, thank you!
def bootstrap_class_for flash_type
case flash_type
when "success"
"alert-success"
when "error"
"alert-danger"
when "alert"
"alert-warning"
when "notice"
"alert-info"
else
flash_type.to_s
end
end
This works better in Bootstrap 3 IMHO.
for those that just need 2 colours for simplicity flash[:notice]
and flash[:error]
:
app/views/layouts/_flash_messages.html.haml
Haml template
- flash.each do |name, msg|
%div{:class => "alert alert-#{name.to_s == 'notice' ? "success" : "warning"}"}
%a.close{"data-dismiss" => "alert"} ×
%div{:id => "flash_#{name}"}= msg
module FlashHelper
def flash_messages
render partial: "layouts/flash_messages", flash: flash
end
end
Easy!
<% flash.each do |name, message| %> <p class="alert alert-<%= name %> fade-in"><%= message %></p> <% end %>
Why not just using Hash for #bootstrap_class_for ?
