Bundler requires Rubygems >= 1.3.6. Run gem update --system
if you have an older version.
It also is not compatible with older versions of passenger, so bring that up to date as well (2.2.15 works).
If you installed RubyGems through apt (which you should never do!), you may see a message giving you a hint to use apt to update.
Some people advise to install the 'rubygems-update-1.3.7' gem on Ubuntu systems if you used apt to install RubyGems.
I did that - and lost all...
This might eventually be fixed by Rails itself.\
Right now this is the way to have the rails_xss plugin not escape the body of ActionMailer mails.
Put this into config/initializers/mailers_without_rails_xss.rb
:
One option is to use partials. Or you can set the @template
field to the name of another action:
class Mailer < ActionMailer::Base
def foo
subject "Hello World"
end
def bar
subject "Hello Universe"
@template = 'foo'
end
end
Sometimes files attain executable-flags that they do not need, e.g. when your Windows VM copies them over a Samba share onto your machine.
From inside your Rails project directory call regularly:
geordi remove-executable-flags
Runs chmod -x
on Ruby, HTML, CSS, image, Rake and similar files.
This script is part of our geordi gem on github.
When you create e.g. a sidebar box that contains headlines and paragraphs, the final paragraph's margin in that box will create an undesired 'bottom padding' inside that box.
Here is a Sass mixin that you can apply to such boxes. It makes the last child's bottom margin disappear:
=hide_last_margin
>*:last-child
margin-bottom: 0
Use it like this:
.sidebar_box
p, table, ul
margin-bottom: 1em
+hide_last_margin
Does not work in versions of <IE8

You may omit the /path/to/link_name
to have a link with the same filename appear in the current directory
ln -s /path/to/file /path/to/link_name
unlink link_name // to remove the link and not where it is pointing at
With this plugin, you can create a scalable tooltip by just using a single background image for the tooltip body.
Prototip allows you to easily create both simple and complex tooltips using the Prototype javascript framework.
Please note: "Permission to use Prototip on your domain is required and can be obtained by paying a small fee."
The point is, evented I/O is not magic scalability pixie dust, and like anything, there is a tradeoff.
Boolean attributes can now be set by appending "which", "that" or "who" at the end:
Given there is a movie which is awesome
And there is a movie with the name "Sunshine" that is not a comedy
And there is a director who is popular
Instead of "and" you can now also use "but" and commas to join sentences:
Given there is a movie which is awesome, popular and successful but not science fiction
And there is a director with the income "500000" but with the account balance "-30000"

When you roll custom URLs with hacks like routing-filter, you can put a spec like this into spec/routing/routing_spec.rb

This will eventually be integrated into jQuery UI with the multiple: true
option, but right now this is the way. Credits go to jqueryui.com.
Don't use should validate_format_of(...)
because that matcher works in weird ways. Use the allow_value
matcher instead:
describe Email, '#sender' do
# > Rspec 3 should syntax
it { should allow_value("email@addresse.foo").for(:sender) }
it { should_not allow_value("foo").for(:sender) }
# Rspec 3 expect syntax
it { is_expected.to allow_value("email@addresse.foo").for(:sender) }
it { is_expected.not_to allow_value("foo").for(:sender) }
end

Problem:
Keyboard layout reverting to US on (every) reboot
Cause:
I found the same problem, but only on my wife's account. I'd set her keyboard layout to UK through Gnome preferences and every time the US layout would reappear and be selected frustratingly.\
It turned out that on the gdm login screen her choice of keyboard layout in the discreet option bar at the bottom of the screen was set to US. That was then overriding the Gnome layout preference.
Solution:
Selecting the appropriate keyboard layout on the next login solved the...

You can write regular expressions some different ways, e.g. /regex/
and %r{regex}
. For examples, look here.
Remember that it is always a good idea to match a regex visually first.
Literal Characters
[ ] \ ^ $ . | ? * + ( )
Character Classes
[ae] matches a and e, e.g. gr[ae]y => grey or gray => but NOT graay or graey

popthis is awesome when used with inaction_mailer.
Install the gem:
sudo gem install popthis
Start the server:
popthis tmp/sent_mails/ # e.g. the folder containing the .txt-mails generated by inaction_mailer
Now, configure your mail client as follows:
Server: localhost
Protocol: POP3
Port: 2220
Username: anything
Password: anything

The following example is from the Cucumber wiki:
Given a blog post named "Random" with Markdown body
"""
Some Title, Eh?
==============
Here is the first paragraph of my blog post. Lorem ipsum dolor sit amet,
consectetur adipiscing elit.
"""
That multi-line string will be given as the last block argument in your step definitions:
Given /^a blog post named "([^\"]*)" with Markdown body$/ do |title, markdown|

Use the attached initializer to do stuff like this
str = "abc"
str.imbue(:foo => 'foo value', :bar => 'bar value')
puts str.foo # 'foo value'
puts str.bar # 'bar value'
So you screwed up and copied Paperclip secrets from one project to another. Here is a semi-automatic, painful way to migrate your existing attachment files to new locations.
You need to follow this step by step, do not just copy the whole thing into the console!
# 1. Get old paths by doing something like this on the console:
old_paths = ModelWithAttachment.all.collect { |m| [m.id, File.dirname(m.image.path(:original)).gsub(/original$/, '') ] if m.image.file? }.compact.uniq
# 2. Now change the Paperclip secret on the co...
Capybara does not play nice with sites that have some actions protected by SSL, some not. A popular way to implement this in Rails is using the ssl_requirement plugin by DHH, which redirects a requests from HTTP to HTTPS if the requested action requires SSL and vice versa.
Capybara follows the redirect, but seems to forget the changed protocol for the next request. The only hack-free workaround right now is to use URLs in lieu of paths everywhere (links, form actions).
For a hackful fi...
