Posted in How can I switch from RVM to RBENV?

found this guide, worked for me on development - haven't tried on production yet.


Hey I followed the deploying guide for Ubuntu 20.04 LTS. When deploying my application I get the following error. Googling around I haven't been able to locate any leads on what to do... anyone have a suggestion to try? Thanks!

My current project I'm attempting to deploy is Rails 5.1.6 as well.

Posted in How can I switch from RVM to RBENV?

I have followed the deployment capistrano guide in the past on GoRails. At the time I setup using RVM... what are the steps to switching from RVM to RBENV? I think I would need to changeover on my development machine and my production machine and then switch over the gems in my Gemfile.

I'm not sure how to (1) Change over from one to the other, (2) if there are any additional steps I'm not thinking of...

Thanks Chris! I think that's how I assume it will go as well. The database is on it's on SQL Server, also great point about the uploads I forgot about that. What about the server's ip address? Would I essentially setup the other server and then just point my domain name to the new ip address? Your website has been very helpful in so many ways - and the quick responses and such are really amazing. Thanks so much I'm very happy to be a subscriber!

Posted in What's a good way for upgrading a server?

I have an internal application that is running fine now, but I need to upgrade the version of Ubuntu Server on it. I have put this off wayyyy too long. Essentially I have a "VMWare box" on the company's network that has my current Ubuntu Server that's still (embarrassingly) running 14.04 LTS. I have been deploying updates using the Capistrano guide found here at Go Rails.

My approach now was going to be for my IT person to setup a new server with Ubuntu 20.04 LTS and I would use the Rails guide here at Go Rails to setup a new server and deploy to it. After that I'm not sure what the best way would be to flip over the servers to have a, as much as possible, seamless transition. Anyone have any recommendations or things to look out for?

Sidenote, I was told by someone else that Docker would greatly simplify my life in this regard. While I am more than happy to explore that next I just want to get things upgraded and then I can look into some solution like that next. Thanks!

I wanted to generate a pair of partials. My approach is prerhaps flawed, but I was generating the same "id" for both partials when doing the replace for "NEW_RECORD". The way I managed to get around that was...

(my apologies I don't know how to add code block here...)

content = this.templateTarget.innerHTML.replace(/NEW_RECORD/g, Math.floor(new Date().valueOf() * Math.random())).replace(/NEW_SECOND_RECORD/g, Math.floor(new Date().valueOf() * Math.random()))

Perhaps this is helpful to anyone else that comes across this post.
