“...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...”
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…
