How can I add a favicon in Active Admin. I am using rails 3.2 and active admin 0.4.3
Though this question is about an older version of ActiveAdmin, as of this commit ActiveAdmin supports favicons in the initializer. Around line 145 of active_admin.rb for me:
# == Setting a Favicon
#
# config.favicon = '/assets/favicon.ico'
HTH the next person who comes along. I almost did the top-voted answer...
Until they support favicon you can do the trick:
$(document).ready(function(){
$('head').append("<link href='favicon.ico' rel='shortcut icon'>");
});
You'll have to add it to your ActiveAdmin.rb initializer like so :
module ActiveAdmin
module Views
module Pages
class Base < Arbre::HTML::Document
def build_active_admin_head
within #head do
insert_tag Arbre::HTML::Title, [title, render_or_call_method_or_proc_on(self, active_admin_application.site_title)].join(" | ")
insert_tag Arbre::HTML::Link, rel: 'shortcut icon', href: '/favicon.gif'
# Change the href used in this line ^
active_admin_application.stylesheets.each do |style|
text_node(stylesheet_link_tag(style.path, style.options).html_safe)
end
active_admin_application.javascripts.each do |path|
script :src => javascript_path(path), :type => "text/javascript"
end
text_node csrf_meta_tag
end
end

For the site I'm building with Middleman, I am localizing entire templates as described in the docs on the bottom of the "Localization" section. So the relevant part of the file tree looks like this:
/localizable
|
|- index.en.html.haml
|- index.ru.html.haml
|- about.en.html.haml
|- about.ru.html.haml
I can link from the index.en page to the about.en page using the path helper like so:
= link_to 'about me', '/about.html'
But when I try to do a similar trick to create a link from the index.ru page to the about.ru page:
= link_to 'some russian text', '/russian/about.html'
the helper doesn't work. It ignores the /russian folder and creates a link to /about.html in root.
Am I missing something or is the path helper unusable for localized templates? Is the only option to use the <a> tag directly?
============
Update1: relevant parts of my config.ru file:
set :css_dir, 'stylesheets'
set :js_dir, 'javascripts'
set :images_dir, 'images'
activate :relative_assets
set :relative_links, true
activate :i18n, :langs => [:en, :ru], :lang_map => { :en => :english, :ru => :russian }
activate :blog do |blog|
blog.prefix = "blog"
blog.paginate = true
end
# Build-specific configuration
configure :build do
# For example, change the Compass output style for deployment
# activate :minify_css
# Minify Javascript on build
# activate :minify_javascript
# Enable cache buster
# activate :asset_hash
# Use relative URLs
# activate :relative_assets
# Or use a different image path
# set :http_prefix, "/Content/images/"
end
Cant really say what is the problem without seeing your config.rb file and the structure of your file system.
My guess on your problem would be like this here
or it could be real simple that you have to change 'russian' to 'ru', since that is in file name.
Here is a good example
EDIT:
Now with your config.rb , I can see you are using :en as default and :ru as russian
Since you are using :en as default(non prefixed), you dont have to map that. or if you want that to be mapped and not be default you might have to use ':mount_at_root => false' with activate 'activate :i18n,'
Try the following solution
activate :i18n, :langs => [:en,:ru], :lang_map => {:ru => :russian}
Like I said, I simply just removed :en mapping and it worked on my test. Since you make :en as default you dont have to map it. If you want both languages to be mapped correctly then use the following
activate :i18n, :mount_at_root => false, :langs => [:en,:ru], :lang_map => {:en => :english ,:ru => :russian}
I have an uploader (internal use only) that will upload an HTML document to a binary column of a table in my client-facing website. The client facing site has an index that allows the user to view the page as a normal website (using send_data h_t.html_code, :type => "html", :disposition => "inline"). I also want to give the user the ability to download a PDF of the page. For that I'm using wicked_pdf.
The entire problem seems to stem from the fact that the data is stored in the database. As strange as it sounds, it is vital to business operations that I get formatting exact. The issue is I can't see any image, and the stylesheets/style tags don't have any effect.
What I've tried-
Gsub-
def show
html = HtmlTranscript.find(params[:id])
html_code = html.html_code.gsub('<img src="/images/bwTranscriptLogo.gif" alt="Logo">','<%= wicked_pdf_image_tag "bwTranscriptLogo.gif" %>')
html_code = html_code.gsub('<link rel="StyleSheet" href="" type="text/css">','<%= wicked_pdf_stylesheet_link_tag "transcripts.css" %>')
transcript = WickedPdf.new.pdf_from_string(html_code)
respond_to do |format|
format.html do
send_data transcript, :type => "pdf", :disposition => "attachment"
end
##### i never could get this part figured out, so if you have a fix for this...
# format.pdf do
# render :pdf => "transcript_for_#{#html.created_at}", :template => "html_transcripts/show.html.erb", :layout => false
# end
end
end
Using a template-
#Controller (above, modified)
html = HtmlTranscript.find(params[:id])
#html_code = html.html_code.gsub('<img src="/images/bwTranscriptLogo.gif" alt="Logo">','<%= wicked_pdf_image_tag "bwTranscriptLogo.gif" %>')
#html_code = #html_code.gsub('<link rel="StyleSheet" href="" type="text/css">','<%= wicked_pdf_stylesheet_link_tag "transcripts.css" %>')
transcript = WickedPdf.new.pdf_from_string(render_to_string(:template => "html_transcripts/show.html.erb", :layout => false))
#view
<!-- tried with stylesheet & image link tags, with wicked_pdf stylesheet & image link tags, with html style & img tags, etc -->
<%= raw(#html_code) %>
And both will generate a transcript- but neither will have style OR image.
Creating an initializer-
module WickedPdfHelper
def wicked_pdf_stylesheet_link_tag(*sources)
sources.collect { |source|
"<style type='text/css'>#{Rails.application.assets.find_asset("#{source}.css")}</style>"
}.join("\n").gsub(/url\(['"](.+)['"]\)(.+)/,%[url("#{wicked_pdf_image_location("\\1")}")\\2]).html_safe
end
def wicked_pdf_image_tag(img, options={})
image_tag wicked_pdf_image_location(img), options
end
def wicked_pdf_image_location(img)
"file://#{Rails.root.join('app', 'assets', 'images', img)}"
end
def wicked_pdf_javascript_src_tag(source)
"<script type='text/javascript'>#{Rails.application.assets.find_asset("#{source}.js").body}</script>"
end
def wicked_pdf_javascript_include_tag(*sources)
sources.collect{ |source| wicked_pdf_javascript_src_tag(source) }.join("\n").html_safe
end
end
did absolutely nothing, and I have no idea what to try next.
As a side note, the code to view the HTML version of the transcript is as follows:
def transcript_data
h_t = HtmlTranscript.find(params[:id])
send_data h_t.html_code, :type => "html", :disposition => "inline"
end
It requires no view, as the html data is stored in the database, but I get image, style, etc. Everything works with the HTML version- just not the PDF.
I'm on ruby 1.8.7 with rails 3.0.20.
Solved-
As it turns out, there was more than one issue at hand.
1- Installation of wkhtmltopdf for Ubuntu via $apt-get install does not quite do the trick for what I wanted...
see http://rubykitchen.in/blog/2013/03/17/pdf-generation-with-rails
(there may have also been an issue with having not previously run sudo apt-get install openssl build-essential xorg libssl-dev libxrender-dev, as when I did, it installed a number of components I did not previously have.)
2- The HTML files I had uploaded contained image & style code that was breaking the formatting. I fixed it with this...
def rm_by_line(which = 0, line1 = 0, line2 = 0)
h_t = HtmlTranscript.find(which)
line_by_line = h_t.html_code.split('
')
for i in line1..line2
line_by_line[i] = ''
end
line_by_line = line_by_line.join('
').strip
return line_by_line
end
Then, all I had to do was pass which lines I wanted to remove.
(I had to split the parens with a carriage return because '\n' didn't function properly when calling 'raw' on the returned string.)
3- wicked_pdf_stylesheet_link_tag and wicked_pdf_image_tag were undefined. I had to inline the style formatting I wanted into a layout I created (turns out wicked_pdf_stylesheet_link_tag used asset pipeline wich my ruby/rails did not implement, which also means I had to get rid of the javascript helpers) and created a helper for wicked_pdf_image_tag, making a switch in the layout for which image tag (image_tag or wicked_pdf_image_tag) to be used.
4- I needed both a .html.erb & a .pdf.erb for my templates, so I made both.
5- Got rid of WickedPdf.new.pdf_from_string in favor of linking to either html or pdf by using :format => 'html' or :format => 'pdf' in the link_to tag.
I'm working on migrating a rather big project to Rails 3.
Here's my controller action:
def recent
#account = Account.find(session[:account_id])
render :layout => false
end
Here's my recent.json.erb file
formatted_account =
{
:code = 1,
:id = #account.id,
:prefix = 2
}
formatted_account.to_json()
I'm using jQuery.getJSON to get this data, when I get the response, this is what I get:
[{"code":1,"id":"1 "prefix":2}]
Instead of
[{code:1, id:1, prefix:2}]
I had to use safe_html in some other pieces of code to solve escaping issues like this but in this case I can't figure out how to solve without getting rid of the .json.rb file and rendering a json object in a proper way.
html_safe did the trick:
formatted_account =
{
:code = 1,
:id = #account.id,
:prefix = 2
}
formatted_account.to_json.html_safe
If you want to build up json from a template you'll need to use some kind of builder as ERB won't really cut it.
JBuilder comes commented out in a fresh Rails 3.2 Gemfile. Haven't used it myself but it seems well thought out with a clean DSL. There's also a list of links at the bottom of the README on the JBuilder github page.
RABL is another tool for building JSON, as well as supporting multiple other formats.

I wanna override html code when working with active_admin gem in Rails; because the nav-bar and many elements in these gem's views are different with my views (other pages). I hope that has a way to change html code without changing css manually! Thanks
It is not very easy , activeadmin use DSL for building html (called "Arbre")
You have to monkey patch every page class, also , it may prevent customizing of css too.
For example to move sidebar to left, create initializer with next patch.
class ActiveAdmin::Views::Pages::Base < Arbre::HTML::Document
def build_page_content
build_flash_messages
div :id => "active_admin_content", :class => (skip_sidebar? ? "without_sidebar" : "with_sidebar") do
build_sidebar unless skip_sidebar?
build_main_content_wrapper
end
end
end
default method was
def build_page_content
build_flash_messages
div :id => "active_admin_content", :class => (skip_sidebar? ? "without_sidebar" : "with_sidebar") do
build_main_content_wrapper
build_sidebar unless skip_sidebar?
end
end
The full list of classes used for rendering can be found here , so some of them you need to patch.
https://github.com/gregbell/active_admin/tree/master/lib/active_admin/views
Be ready for a big piece of work.
UPD. Gem for changing activeadmin sidebar position

The i18n is configured in the rails 3.0.3 project :
config.i18n.default_locale = :fr
In my dev environnement, everything works fine with price in € and text (like next previous from will_paginate) correctly displayed.
In production environnement, everything is in english and in $.
Where can i found the problem of my i18n ?
What am I missing in i18n in production?
More Info:
On the production server in the rails console production :
irb(main):002:0> I18n.config.default_locale
=> :fr
2Nd Edit
Is there a way to display I18n properties or config in a debug or in a view?
I think this is related to this bug: http://groups.google.com/group/rubyonrails-core/browse_thread/thread/1fe3e88f9fe73177/ .
18n.locale is called before the config.i18n.default_locale is
propagated to the I18n class.
I will try to also change it in config/initializers/locale.rb. According to 2.2 Optional: Custom I18n Configuration Setup in http://guides.rubyonrails.org/i18n.html, you should also change it in config/initializers/locale.rb . Hope this will fix it for you.
Resolved by adding config.i18n.locale = :fr in addition of the default config.i18n.default_locale = :fr in my application.rb
I had this problem with rails admin. But I believe it is the same with any Rails app
At the beginning I have set locale statically in application.eb.
Later I have solve this be removing this a from application.rb
if ENV['language']
config.i18n.default_locale = ENV['language']
else
config.i18n.default_locale = :he
end
And just leaving this in rails_admin/application_controller.rb
(or just application_controller.rb for regular rails app)
before_action :set_locale
def set_locale
I18n.locale = params[:locale] || 'he'
end
def default_url_options
{ locale: I18n.locale }
end
Also a nice tuturial on how to set i18n locale based on Url:
