Yeah, AJAX requests don't work like a normal form submit. Redirects won't be followed by the browser like a normal page view, since you didn't make a normal request. You can redirect client side in the success callback if you want, or have the server do it in a create.js.erb response.

That works too! And will allow you to send files as well.

Hey Gus!

You would just pass in a Javascript object into it, similar to a Ruby hash.

Rails.ajax({
  url: '/donations',
    type: 'post',
    data: {
      amount: 900,
    }
})

Or

params = { amount: 900 }
Rails.ajax({
  url: '/donations',
    type: 'post',
    data: params
})

I'm not real sure on this one, let us know if you find more details. I didn't find much on a quick google search, but I thought that Rails would automatically use the current request's subdomain/domain so you wouldn't have to do anything.

Hey Dean!

You don't have to use an SVG, but it's helpful and what we recommend because you can grow and shrink an SVG without it getting blurry.

You'd use Adobe Illustrator, Inkscape, Sketch, Figma, etc to create an SVG.

render_svg is a wrapper around inline_svg that we made so it embeds your SVG contents into the page and saves making another HTTP request to make your site faster.

If you want to use a png or jpeg, you can just replace that with a regular image_tag that points to your logo.

This would help you create new Rails apps with different versions. Bundler already handles separate Rails versions for each app, so that's already handled for you. It installs whatever is in the Gemfile and uses that. Sometimes you may need to run "bundle exec rails" to make sure it uses the app's Rails version, not the globally installed version.

You can definitely become a junior developer without knowing math super well. One of the nice parts about web development is that you are primarily working with HTTP requests and strings, not math. It's a great area to be in and unless you're building algorithms or something super performant, you won't have to worry about much math being involved day-to-day.

Oh yeah! I forgot about that change recently for Catalina. You probably want to use ~/.zshrc instead now.

Sounds like you're simply missing the RAILS_MASTER_KEY env var. Set that up so that Rails can decrypt the credentials and you will be set.

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

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!

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?

Sounds like you missed the exec $SHELL step.

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

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.

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
