Posted in Configure ruby projects of old version

You can do:

gem install rails -v 5.1.7
rails _5.1.7_ new myapp

Here's a gist that contains Reddit's popularity algorithm that you could use. It's pretty simple and just uses upvote, but you could add in comments and impressions to the calculation too. https://gist.github.com/nanosplit/db42e507c5d1d984b664868db10a3669

This is another approach that you should check out. https://www.akitaonrails.com/2016/10/31/ruby-on-rails-implementation-of-a-proper-ranking-popularity-system

Posted in Is Gorails's jumpstart worth the price?

There was a good little discussion Reddit about it. I also posted some notes about it there as well to help explain the difference between the free and pro versions: https://www.reddit.com/r/rails/comments/drl0q2/is_gorailss_jumpstart_worth_the_price/

Hope that helps, but if you have any other questions I'm happy to help!

Posted in Ruby on Rails ActionMailer Images Issue

Hey Maximilian!

I haven't actually done this before, but it looks like you're mostly on the right path. I found this on Stack Overflow that looks very similar. https://stackoverflow.com/a/25810153

Does the email have the image as an attachment and it's just not showing inline?

Posted in Deploy Ubuntu 18.04 Bionic Beaver Discussion

Sounds like you missed the exec $SHELL step.

Posted in Can not use toast of bootstrap in rails

Sounds like you missed a step. I just updated the repository to include toasts in the example and they work just fine.

https://github.com/gorails-screencasts/bootstap-with-webpack-4/commit/49846a028f0d6674b0024fbd4c1f6051c8757884

Compare your code with the repository and see what you missed.

Still waiting on them to release those Ruby versions. You can use a Ruby Docker image instead or compile and cache Ruby as part of the steps. Other than that, we just have to wait for 2.6.5 support to use setup-ruby. :(

Sounds like you probably missed a step somewhere. I just installed Rails 6.0.2.rc1 and went through the screencast. Everything works correctly.

Posted in Ruby 3x3 Performance

Ruby 3 will have both Fibers and Guilds. Matz talked about it in the Rubyconf keynote this year: https://www.youtube.com/watch?v=2g9R7PUCEXo

Controller methods are not available in the view unless you expose them with helper_method :sort_column

Yeah, that would probably work fine for now. I'm not sure when Rails 6.1 will come out but it might be a little while so you'll probably need a solution like this until then. This basically replicates what Shrine would do for you.

Does it render a different layout? And if so, have you included the stylesheet tag in that layout?

Passenger is an Ubuntu Linux package, it will install any dependencies required automatically. You don't have to worry about them.

You can just skip to the install NGINX + Passenger step if you don't want to install Rails for whatever reason.

Posted in What makes you like Ruby/Rails?

I personally love Ruby because the language is designed for humans first and foremost. You don't have to jump through hoops to make the computer understand it, so you can spend your time thinking about how to communicate ideas in your code. That saves a ton of time in development, and humans are typically the most slow and expensive part of software development.

Rails takes advantage of that and assumes you know the basics of web development and does as much as it can for you. You don't have to worry about the different between GET and POST params, they're just available to you in one spot. There are tons and tons of situations where Rails has already got tools for something I wanted before I knew I wanted it. That's amazing.

The downside is it isn't cool anymore, but if you're doing things just because it's cool, you'll probably be wasting lots of your time. 😜

Posted in How to import javascript from Gems with webpacker

Yep, you can do that. Or if they have a node package, you can use that instead.

Posted in How to import javascript from Gems with webpacker

Just import it in app/javascripts/packs/application.js

import "../myfile"

And put your code in app/javascripts/myfile.js

ActiveStorage URLs always go through your Rails app. That's how they generate the resize 200x200 on the fly without precomputing it. That's the primary downside to using ActiveStorage right now.

In a future version of Rails, they will have an option to use direct urls to AWS, but you can't do that right now.

If you want this feature today, you'd be better off using Shrine for file uploads.

Lockbox or attr_encrypted are great for that. You just define an encrypted column instead of your normal one and add a secret key.
