I use both RSpec and Minitest, but prefer Minitest. It’s not quite as feature-rich as RSpec, but I find that I prefer the tests I write in Minitest - they are more Ruby-ish, and aren’t as reliant on RSpec’s DSL to work. I don’t use around callbacks in RSpec very often, but it is something I recently found myself wanting...
There’s a bit of a mystery about how relevant favicon.ico files are in 2024. Like it not though, they are the lowest common denominator, so they still have some use. Today I learned about a handy option that can be passed to ImageMagick that will automatically resize a source into a range of common dimensions to be packed into an...
I’m a big fan of Bootstrap, I use it a lot. I’ve used it for many years, and with the recent support for theming with CSS variables, and for their utility API, I’ve found I can have the best of both worlds - a rich and capable library of components, along with an extensive class-based approach for making tweaks to...
This is a tip I re-discover every couple of years, then forget until I find my menu bar getting a bit cluttered up again. Holding down the Command key allows menu icons to be dragged backwards and forwards along the menu bar to order them. This is available for all items other than the control center and date/time, including system...
I’m sure this is all over testing-library documentation, but I haven’t had to do this before, so I think it’s worth a quick post about. If I’m writing a testing-library assertion, every now and then the test won’t pass, because the element I expected to be present, was not. Usually, when this happens, a snippet of the DOM will be...
Stretched links have been a feature of Bootstrap for some time, but it’s quite a useful technique to understand, because the functionality it offers - expanding the tap target of an element, works for any element that can be interacted with with a tap or mouse gesture, not just links. Some common examples include: Buttons Inputs Labels The way that...
Throughout my career, I’ve always had at least one project on the go outside work - call this a personal, learning, or passion project - it all amounts to the same. I’ve got a lot of benefit out of these projects - sometimes, I approach them deliberately to try out a new technique or tool. Sometimes, I just enjoy the...
Just a quick little way to reformat or otherwise transform a value to be used as the label in a select, radio button, or checkbox collection group in a Rails form: Given I have an enum defined like so: class User enum :distance_unit, { mi: "mi", km: "km" } end And translations defined like so: en: distance_units: km: Kilometer (Metric)...
Bad (but not obviously so): data = { greeting: "Hello, world!" } ERB.new(" <h1>Show greeting:</h1> <p><%= greeting %></p> ").result_with_hash(data) # => <h1>Show greeting:</h1> <p>Hello, world!</p> The question is - what happens if greeting is something different…like <script>alert('greeting!')</script>? Perhaps, if you’re used to Rails, not what you might expect: data = { greeting: "<script>alert('greeting!')</script>" } ERB.new(" <h1>Show greeting:</h1> <p><%= greeting %></p>...
For quite a while, I managed to find something interesting to write up each work day. Unfortunately, life got in the way, and as is easy to do, this habit stopped. I’m hoping to get back into writing, and I’m trying to do this by making it easier to write up a post without leaving my flow as much. To...
