This was an amazing kickstart for me learning a new language and framework. Rails seems awesome. Thank you for this!!

[@KapnKregg]

I got started with Rails about 12 years ago and have bounced between LOTS of other frameworks and languages during that time. Rails is still the most sane and well designed of all the frameworks I've ever used and still amazed that it's not used everywhere.

[@Neoclassicalmaese]

it fascinates me really. I switch between a lot of different environments for my professional work, and to this day in terms of pushing something out to an MVP nothing, NOTHING beats Rails. The closest thing I can find is Laravel, but performance wise and documentation/tutorials/examples Rails is still a blessing. People complain about the performance, but I think it has more to do with not following proper standards than anything else. Rails is still a beast in this regard.

@kapnkregg if you are interested to write examples articles on ruby on rails pls reach me at [e-mail]

[@TheGlobalNetworker]

wow! it has been 12 years... so do you think Django/Python will outgrow the advantages or Ruby/Rails ? as all the new startups are into AI,ML, Bigdata etc...... etc

[@sebastiangudino9377]

@@TheGlobalNetworker Django is probably also going to go down. Currently the trend is going in favor of NodeJS. Specially with the rise of modern "full-stack" Frameworks like Next.js and Svelte-Kit. Not saying that Django and Rails are bad, not that Javascript is better. Just talking about number of users here

[@javier.alvarez764]

it's because you can do front end and back end using javascript

[@alexlun4464]

Nicee thanks a lot!!!! I'm just 3 weeks old with rails and most resources rely on the documentation. Thanks for being one of the 5 video tutorials on youtube on ruby on rails

Finally Ruby on Rails course in 2020.. Thank You so much for making this.. Long live ruby and rails..

[@andrewwedstrom]

I'm working on a new project (my first real rails app) and whenever I got stuck I procrastinated by watching this video. Every time, within a few minutes you inadvertently answered my question and got me unstuck. Thanks!

It was so refreshing to see a crash course with tests included.

What do you think, will Rails ever comeback to be a hypie-thing?

To make the time format work on Rails 7, use `to_fs` or `to_formatted_s` instead of `to_s`

also for rails 7.0, in 1:13:05, you have to either do or , since in link_to, 'method: :delete' is deprecated and rails ui js is deactivated by default. an additional note for the new 'link_to' code is to update your entries_controller.rb's destroy method to this line: 'format.html { redirect_to root_path, status: :see_other, notice: 'Entry was successfully destroyed.' }'.
