Datepicker not hidden initially when using ui-date with angular-ui, jquery-ui, and Chrome

JqueryUI version: 1.8.6 Angular-ui version: 0.2.1 Chrome version: 23.0.1271.95 Turns out this is an issue with Chrome and JqueryUI css and specifically the .ui-helper-hidden-accessible class. jquery-ui.css .ui-helper-hidden-accessible { position: absolute; left: -99999999px; } That is a lot of 9's for Chrome apparently. Removing one of the 9's fixes the issue: .ui-helper-hidden-accessible { position: absolute; left: -9999999px; }

Mountain Lion | Nokogiri | tiny_tds | homebrew | libiconv

Neither nokogiri nor tiny tds were detecting libiconv, so my solution was as follows: --- brew install libxml2 libxslt brew link libxml2 libxslt --- wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz tar xvfz libiconv-1.14.tar.gz cd libiconv-1.14 ./configure --prefix=/usr/local/Cellar/libiconv/1.14 make sudo make install --- gem install nokogiri -v '1.5.2' -- --with-xml2-include=/usr/local/Cellar/libxml2/2.8.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.8.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26 --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib gem install tiny_tds -- --with-freetds-include=/usr/local/include --with-freetds-lib=/usr/local/lib --with-iconv-include=/usr/local/Cellar/libiconv/1.14/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.14/lib

Rails 3.1 Flash messages and Validation errors

I am using the twitter bootstrap for my styles and haml for my markup, but any will do. If you are not using haml, you should remedy that problem right now. HAML html2haml I have included an example for a Devise view as well.

Flash messages

// views/layouts/application.html.haml .container - flash.each do |key, value| .alert-message.fade.in{:class => "#{key}", "data-alert" => "alert"} %a.close{:href => "#"}x %p= value

Form errors

// views/posts/new .content .hero-unit = form_for @post do |f| = render "shared/error_messages", :target => @post // views/devise/registrations/new .content .hero-unit = form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| = render "shared/error_messages", :target => resource // views/shared/_error_messages.html.haml - if target.errors.any? .alert-message.block-message.error{:"data-alert" => "alert"} %a.close{:href => "#"}× %p %strong = "#{pluralize(target.errors.count, "error")} prohibited this record from being saved:" %ul - target.errors.full_messages.each do |msg| %li= msg

Rails Nested Form Validation Message

When validating a nested form, the validation message includes the nested model name. Sometimes you may not want this. This can easily be addressed with i18n in your en.yml.

class Person < ActiveRecord::Base has_many :dogs accepts_nested_attributes_for :dogs validates :name, :presence => true end class Dog < ActiveRecord::Base belongs_to :person validates :collar_color, :presence => true end

Now when we receive the error message on the form it looks like this:

Name can't be blank Dog Collar color can't be blank

But it is clear that the collar color is referring to the dog, so let's fix that in en.yml

en: activerecord: attributes: person: dogs: collar_color: "Collar color"

Notice that 'dogs' is tucked inside of 'person'

Now our error messages read

Name can't be blank Collar color can't be blank

Good teams don’t just do their work, they think about how they are working and why they are working. They analyze why they succeeded or failed. They don’t try to hide their mistakes, but expose them and learn from them. No one stumbles into excellence.
