This week in Rails: SQL colors, reversible column defaults and more!

Posted by kaspth


Hello? This is your captain Kasper speaking.

We’re just about ready to take to the skies for our weekly cruise through the news. I took a flight course once, and walked away from the crash in flying colors. If my instructor had made it out, I’m sure he would be proud too.

Look at us, we’re already taking off - hey, is that light supposed to be blinking?

This Week’s Rails Contributors

26 daring pilots brimmed the horizon with their commits this week. There were loops and barrel rolls galore - you should have been there! Oh, but you can. See the last item if you feel the need for speed (and contributing).

When SQL Output met Rainbows

In Rails 5 you’ll see your SQL has gotten a fresh coat of paint - several in fact. Now common SQL statements appear in color when sprouting up in your logs. Check the link for the color map.

change\_column\_default Gains Reversible Syntax

Gone are the thrills of remembering past defaults, when you changed it for a column. Both from and to can be passed now: change_column_default(:posts, :state, from: nil, to: "draft")

If all your life’s ROFLMAO’ing have left you with ass left to laugh off, you’ll be ready to migrate and roll back on the floor laughing the remainder of your rear right off over this.


Windows Users Needs the Latest Development Kit

If you’re a Windows user and witness to the horror of rails new failing with native gems not being able to be installed - rejoice! You need the latest Development Kit version, which our getting started guide will now tell you.


where with Association Names are Closer to 4.2

To prevent ambiguity and potential collisions, association names in where are assumed to reference the table name.

default\_render Can Yield When Template is Missing

When a Rails 5 controller action have no corresponding template, Rails renders head :no_content. Before libraries were hooking into the missing template exception being thrown. Now default_render takes a block and the hook is back.

One More Thing™

Feel the need to contribute?

From time to time DHH opens issues on Rails about stuff he’d like implemented. As long as someone hasn’t laid claim to it in the comments (or is assigned) it’s yours to take a stab at.

That’s a wrap

That’s all for This week in Rails. As always, there are many more changes than we have room to cover here, but feel free to check them out yourself!

Have you been thinking about writing for us, but you’re scared of putting yourself out there? Don’t worry, you can help our editors improve their writing with thoughtful critique and general grammar policing.
