“...I've been working since 2008 with Ruby / Ruby on Rails, love a bit of Elixir / Phoenix and learning Rust.
I also poke through other people's code and make PRs for OpenSource Ruby projects that sometimes make it. Currently working for InPay who are based in Denmark...”
Whilst trying to clean up old blog posts. I thought I’d just re-assign the whole post on the console. However, the content of the post had code examples and these examples were being interpolated. This makes sense but isn’t what I wanted. These are all (nearly) equivalent other than the new lines.
s =<<-STR
#{Time.now}
STR
# => "2017-01-17 06:43:48 -0500"
s = %(
#{Time.now}
)
# => "\n2017-01-17 06:43:48 -0500\n"
s = %Q(
#{Time.now}
)
# => "\n2017-01-17 06:43:48 -0500\n"
But what I really want it multi-line string assignment without interpolation.
s = %q(
#{Time.now}
)
# => "\n\#{Time.now}\n"
And without the new lines.
s = %q(
#{Time.now}
).lstrip.chop
# => "\#{Time.now}"
Interesting, ActiveRecord joins issues today. Recently upgraded to Rails 4.0 and working on clearing odd occasional bugs.
Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DISTINCT grapes.id, grapes.* FROM `grapes` INNER JOIN `tickets` ON `z' at line 1: SELECT `pledges`.`id` AS t0_r0, ...., DISTINCT grapes.id, grapes.* FROM `grapes` INNER JOIN `tickets` ....
We specifically need a DISTINCT in here so that we don’t end up with duplicate rows. However, overwriting the select for *eager_load*ed statements isn’t going to work, in fact it appears to just append our select causing the above error. So…
