Ran in to a bug tonight. See it?
def display_value
display_value = notes.blank? ? “untitled” : notes
display_value << ” (#{ shortcut })” unless shortcut.blank?
display_value
end
Need a hint? The symptom was the +notes+ field being unexpectedly changed.
+display_value+ is pointed at +notes+. “<<” then goes ahead and changes that value (which both attributes are pointed at), thus both are [...]
After skimming the “What’s New” posts for several Rails versions without finding anything worth jumping at, it was time to upgrade. While JSON enhancements (fixes) are the driving reason for the move, there certainly are a few “nice to haves” that I’ve been looking forward to checking out.
Partial Updates
Unfortunately, one of the things I’ve been [...]
If you can’t tell… I like posting little “cheatsheet” items here. So, here’s another one that I’ve bumped into again recently after not needing it for a while.
You want to know how many Items are currently in the Store and you’ve got this in your Store definition:
has_many :items
If the Items for this Store have [...]
Isn’t it nice how Rails lets you add form elements using the convention:
store[manager] = Bob Smith
store[location][state] = Wisconsin
store[location][zip] = 53590
And easily process them on the server side with something like:
Store.new(params[:store])
So, why does this:
link_to “Store”, :controller => :store, :action => :show, :store => { :manager => “Bob Smith”, :location => { :state => “Wisconsin”, :zip => [...]
A user recently reported an issue with our emails. The issue being that our links weren’t properly coming through on his Blackberry unit, while links from others looked fine.
After a bit of digging the issue ended up being that:
<a href=”http://seekingalpha.com”>SA</a>
displayed like this (which is desired on the unit):
SA <http://seekingalpha.com>
While this:
<a href=’http://seekingalpha.com’>SA</a>
displayed:
SA
Not sure if ignoring [...]
This really was a snap.
A nice and simple testing recipe (#68) demonstrates how to read in an email from a fixture in just a few lines and pass them to your processing method (MailReceiver.receive in this case).
def read_fixture(action)
IO.readlines(”#{FIXTURES_PATH}/mail_receiver/#{action}”)
end
def test_something
email = read_fixture(”junk_mail”).join
MailReceiver.receive(email)
# assertions
end
And then a few lines on how to feed it “for real”. and [...]
As I discovered today, assert_not_equal has a pretty big problem: it does exactly what you ask it to do.
I just need to make sure that a user has at least one record:
assert_not_equal 0, UserPreference.find_by_user_id(user_id)
As you may have just caught: that is always going to pass. Not a tough mistake when you’re motoring along and [...]
You’d think it would be easy to send an image to a client with a framework as wonderful as Rails.
After doing quite a bit of searching for the simple way, I really didn’t turn up too much. Finally, I decided I would just open the file and write it out the old fashioned way: [...]
Why aren’t my fixtures properly loading their ‘registered’ timestamps correctly?
Ah, the dreaded Year 2038 issue
loads fine: user_registered: ‘2038-01-18 21:14:07′
not happy: user_registered: ‘2038-01-18 21:14:08′
So, that fixture that I just wanted to have ‘a date way out in the future’ will need to be knocked back a few years I guess.
We’ve developed a few batch applications that live in the same directory structure as the Rails app they’re intimate with. So, the lib/foo/test/ contains some tests for the ‘foo’ batch app. lib/bar/test has the ones for ‘bar’ etc.
It was kind of annoying to have seperate rake files though – or worse to need [...]
