Dang it already bought it!
Great book
Really helped me understand docker
The part i am still trying to understand is how to reuse containers properly
I've been trying to get some building automation apps running on it as proof of concept but I am contemplating if docker is even a good fit for something that needs to be always running

Hi,
My new book "Docker for Rails developer" (Pragmatic Programmers) has just launched in early-access beta: https://pragprog.com/book/ridocker/docker-for-rails-developers
It's a light, easy read that will help you get up-to-speed fast. The focus is on practical, real-world usage for developers and will guide you step-by-step. Grab your copy while it's hot... more chapters to follow as soon as they're ready.Not sure? Here's what people are saying about it:This is the book I wish I had when I started delving into Docker.a really enjoyable, clear and informative read[reminds] me of the original DHH Rails book... bravo!When I first saw the title, I might not have been so interested in buying the book given that I'm currently involved in other projects (Elixir! Javascript! Java! Neo4j! etc). However, how wrong I was. This knowledge I can actually export and apply directly to all of my current projects and thus dockerize those environments as well.it has made me rethink the way in which I develop applications.Free prize draw... For your chance to win a free copy, include the following in a tweet "https://pragprog.com/book/ridocker/docker-for-rails-developers #Docker #Rails #RoRTalk @robisenberg" — one winner will be chosen at random.
Cheers,
Rob
p.s. any other help to spread the word would be much appreciated!

All of the product pages have a sharethis toolbar.
I don't know if it's working now, i tried something I found on google.
The other thing I noticed, now it thinks the page is not secure.
Thanks,

This would be a Turbolinks problem, very definitely. Turbolinks only refreshes the head of the page when you do a full reload. It's expected that your scripts will be compiled in the Asset Pipeline and will load once. Ever after, the body of the page is silently replaced via Ajax, thus speeding up the loading of your global libraries (by dint of only loading them on the first page load).
Now the problem comes when you have some code in your page body that your script needs to interact with, so you, being a pro, write proper unobtrusive JavaScript that wires up that connection later. Something like:
$(document).on('click', '.lightbox a', function(){
// do something with $(this), which will be the a (link) you clicked on
});
That should work without any modification, because it is lazy-loading the target at the moment the event fires, rather than wiring up the listener on page load.
I suspect that may be what your code is doing, so look through it for something that looks more like:
$(document).ready(function(){
$('.lightbox a').click(function(){
// do something with $(this), which will be the a (link) you clicked on
});
});
If you find that, either rewrite it to the lazy pattern I showed you first, or if it's too complex to untwist, change the $(document).ready bit to this:
$(document).on('load turbolinks:load', function(){
// ...
});
This will hook into the event that fires after Turbolinks refreshes the body of the page, so everything on the screen will be ready to be extended.

flat_map: https://apidock.com/ruby/Enumerable/flat_map
Then that passes a block, which acts on each member of the Enumerable that called flat_map. That block sorts by the numerical value of x, then reverses.
Does that help?

When this validator runs, what is it comparing? The label or the value? You are passing a combination of the two into your validator and expecting it to guess. You could try either using a hash for the data structure, and being explicit about what you want it to compare:
DURATION_TYPES = {'7 days' => 7, '14 days' => 14 ... }
validates :duration, inclusion: { in: DURATION_TYPES.values }
or you could extract just the second value out each pair (using your existing nested array):
validates :duration, inclusion: { in: DURATION_TYPES.map(&:last) }
Please google "Ruby symbol to Proc" to better understand how that last one works. If you use the first approach, then you will need to change the way you access the constant's values in your select list constructor.

Hi, I'm a newbie to Rails but I have completed Micheal Hartls Tutorial on Ruby on Rails https://www.railstutorial.org and have several websites. Micheal Hartls tutorial uses microposts which include texts and or a picture which is then saved into Database.
The ability to add pictures at the start or later depends not only on how you set up the Database but also the pages responsible for getting and adding data to the Database.
Before you build any website you need to plan what and how that website does things. Failure to do so results in time consuming rebuilds if you want to extend anything you want your website to do.
I agree if you are an experienced Rails programming you should be giving back more than you get. That is how you get more developers using Ruby on Rails
Cheers Dave

You're missing that String#[] when given a Regexp returns the substring that matches that Regexp.
[1] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}
=> ["1020", "950", "50"]
[2] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}.sort
=> ["1020", "50", "950"]
[3] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/]}.sort.reverse
=> ["950", "50", "1020"]
[4] pry(main)> ["AB_1020", "AB_950", "AB_50",].map {|x| x[/\d+/].to_i}.sort.reverse
=> [1020, 950, 50]
[5] pry(main)> ["AB_1020", "AB_950", "AB_50",].sort_by {|x| x[/\d+/].to_i}
=> ["AB_50", "AB_950", "AB_1020"]

flat_map: https://apidock.com/ruby/Enumerable/flat_map
Then that passes a block, which acts on each member of the Enumerable that called flat_map. That block sorts by the numerical value of x, then reverses.
Does that help?

But [["AB_1020", "AB_950", "AB_50"], ["1000", "570"]] has non numerical values too.

Hi,
-- I found this code for sorting an array :
p ["AB_1020", "AB_950", "AB_50", "1000", "570"].partition{|x| x.to_i.zero? }
.flat_map{|x| x.sort_by {|x|x[/d+/]}.reverse}
ouptut
#⇒ ["AB_50", "AB_950", "AB_1020", "570", "1000"]
I know that .partition{|x| x.to_i.zero? } will create an array of arrays :
[["AB_1020", "AB_950", "AB_50"], ["1000", "570"]]
But this part .flat_map{|x| x.sort_by {|x|x[/d+/]}.reverse}
I could understand it.
Thanks.
