Posted in Where to read about changes between Ruby versions?

Mostly I just look at ruby-lang.org for the notes in the blog posts.

Posted in Where is the search bar?

Strange. What does thr javascript console say for errors?

Posted in Where is the search bar?

Try using the search icon in the navbar.

This would be a good one for the Rails github issue tracker.

I would bet they don't have that by default, but could probably be done by pasting the Rails source into your app, editing the toolbar for Trix, and then including your modified copy instead of the Rails JS for it.

ActionCable works great for this. Once the background job retrieves the data, you can have it send an updated partial over to the user and replace it on the page. I do this for server and app status updates on Hatchbox. Works great.

Awesome! I've got a long weekend out of town, but when I get back I can probably crank on a few episodes that start from the very basics.

Posted in How do I work out time slots greater than 5 hours

I don't think there's any way to do this in the database with the current setup, so what you're doing is probably what I would do.

You could cache the results of the report and re-calculate them every day or week on a regular basis so you don't have to run this expensive calculation all the time.

I'd probably stick with what you've got.

Posted in Suggested changes to Ubuntu 18.04 documentation

haha! ive done that many times myself. Coding while tired doesnt work out very well.

Maybe a cool feature to add is checkboxes so you can see which steps youve completed!

Posted in Make http POST request that return xml response

You can run that code in the console by running the same code as you would in your app. response = Documents::CreateSession.new.start

The response will be the return value of start as it currently is setup.

Posted in Suggested changes to Ubuntu 18.04 documentation

The "Installing Ruby" step covers installing git, node, yarn, build essentials and the libssl, libreadline and zlib libraries. Sounds like you might have missed those steps.

Posted in Rails6 autorization method

Most of us prefer the Pundit gem for that. There's an episode on it as well. 👍

Posted in Payment Rails Master Class (SCA) ready?

Not quite yet! I'm still working on it but keep getting distracted with other things. I'm hoping next week I can dedicated a lot of time to getting it all figured out and then re-record the course after that.

Moving a database isn't so easy. You typically incur downtime, or you have to setup streaming replicas and things that are complicated.

  1. You can either pay for DigitalOcean's managed load balancer, or let Hatchbox create one. You probably just need a $5/mo server for that.
  2. If you use their managed database, it's not a server you'll have in Hatchbox, so it doesn't count. They also have managed Redis now too that you could use if you wanted. Having managed databases that you don't have to worry about is really really nice. Hatchbox doesn't do managed yet (and we might never need to if these services keep popping up), so those are worth looking into.
  3. The number is however many servers Hatchbox creates and runs for you.
  4. Depends on how many background jobs you plan on running, but yes, seems good.

Not currently, but I'm actually working on one! What's your knowledge about web development so far? Have you learned anything else or are you starting completely new with Rails?

Posted in Where is "embeddable javascript widget Part 4"?

Looks like I accidentally changed the naming scheme for that episode. 🧐

Posted in Do you measure your app's uptime?

Pretty much has to be an external service, since you want it running independently of your app. And, so you don't have to also monitor and run your own uptime monitoring, most people just pay for something.

I like and recommend HoneyBadger.io will do uptime checks, check-ins, and error monitoring all-in-one. Nice to have those features together in the same app rather than paying for multiple things. They have a free solo-dev option that comes in handy.

You've also got tools like Pingdom that will do performance / uptime. Lots of other options out there too.

Posted in How to use Action Mailbox in Rails 6 Discussion

Most people use Sendgrid or another service to handle mail servers. If you haven't done it before, you should use them and their inbound email functionality. It'll save you a ton of time trying to figure things out.

Posted in SQLite3::SQLException: no such column:

Since it says your comments table has no post_id column, you should check your migrations and make sure you didn't forget to add the column. :)
