Making snapshots fail on AWS

Capybara "within" blocks and CSS pseudoselectors

We're running into an issue where :nth-child doesn't work with capybara CSS marchers. Oddly, the Xpath equivalents work just fine.

Halp?

05/20: Agile Experience Meetup: Designer / Developer pair-cooking show

Robbie will be speaking and live-coding!

When teams integrate Agile and UX practices, the borders between designing and making become increasingly blurry, with siloed work replaced by cross-disciplinary collaboration. For our next Meetup, we'll combine a live pairing session with two talks on collaborating across roles and disciplines. How is pairing better than traditional collaboration? What are some pitfalls to be mindful of? Is it the right choice for your team? After their talks, we'll open up the floor for a panel-style Q&A.

Negate a scope with ActiveRecord

Say you want to negate a scope.

scope :active, -> { where(active: true) }

You start by creating another scope:

scope :inactive, -> { where(active: false) }

Then the underlying column name changes, and you're forced to go back to two different scopes to update it. Ugh.

Wait!

You could have negated the first scope in the second scope!

scope :negate, ->(scope) { where(scope.where_values.reduce(:and).not) }

Now, use it:

scope :inactive, -> { negate(active) }

Boom.

FireSASS in Chrome (source maps)

If you're using SASS and ever wanted to see the original line numbers in your SASS files for debugging purposes, you've probably used FireSASS. Unfortunately, FireSASS is not available in Chrome.

However, you don't need FireSASS in Chrome, as SASS Source Maps totally work.

The following blog post will show you how to enable it.
