capybara integration test with selenium for jquery autocomplete

Note the ‘sleep 1′, didn’t work for me unless I add a wait in between filling in the autocomplete field and mimicking the select.

fill_in(“Client”, :with => @individual.code)
sleep 1
page.execute_script %Q{ $(‘.ui-menu-item a:contains(#{@individual.code})’).first().trigger(“mouseenter”).click(); }
click_on “Save”

ActiveRecord joint table condition notation/syntax

This doesn’t seem to be that well documented.
When you want to do a conditional where clause on a joint table.

You could do this: Model.where().includes(:model_b).where(“model_b_table.attribute = ?”, ‘foo’)
Better way is: Model.where().includes(:model_b).where(:model_b => {:attribute => ‘foo’) )

The end…

Factory girl singletons

Factory_girl is different to fixtures. There’s no way to define 2 user belonging to the same school. Creating one instance of school, we call it as a singleton method. Here’s a drop in monkey patch that stores the instance in a class variable.

Coffee-script in Rails 3

Since Rails 3.1 will have coffee-script as default. For those eager to try it can easily do so with ‘barista’ gem.

Remove invalid escape Xml character easily with regular expression in ruby

I am in a project where there is a huge XML file I need to use SAX parser and unfortunately, to further complicate this matter, we encountered this bug:

(Nokogiri::XML::SyntaxError) "xmlParseCharRef: invalid xmlChar value 25"

Turns out that is caused by  in the document.

So at first I did something pinpoint to this problem before I submit the string to push parser:

data.gsub('', ''')

As this kind of an apostrophe in the text.

Turns out, I got another one later:

(Nokogiri::XML::SyntaxError) "xmlParseCharRef: invalid xmlChar value 29"

With some more googling, I realize anything below character x20 is invalid, then I see a funny post:
Removing Invalid XML Character

Works, but not elegant, especially when you know there is something called regular expression in the world.

This is the easiest:

data.gsub(/&#x[0-1]?[0-9a-eA-E];/, ' ')

Of course for character like  when you want something actually a character replace that, you would definitely need to do your own replace first before you do this sweeping.
