ransack | Object-based searching | Application Framework library

I have tried to implement the search code using https://www.botreetechnologies.com/blog/implementing-advanced-search-in-ruby-on-rails-with-ransack but it does not return any values when I search. It passes the cont value but the select statement always uses "LIKE NULL" I want to display records with the searched group_id This is the search in my controller:

Im running ruby version 2.6.1 with docker. Rake gem is version 13.0.1.
Whenever I tried docker-compose up, it always fails and throws this error everytime:
This error did not exist before.

I was about to implement a search function where users can filter a datetime column.

I am currently using rails datetime_field_tag however I can't seem to make it work with ransack where people can choose a date with time in hours and minutes then either AM or PM.

Users can enter datetime in this format: dd/mm/yyyy hh:mm AM/PM

The column that i am searching for is in datetime format, ex: 2021-05-12 09:09:48

What's the best way to implement this one? with ransack or not? and how?
just my first time implementing datetime search function with ransack,

I tried searching online but i cant seem to find a good solution. thanks.

I have a working code that filter out one row of if the conditions are met

I have data on several machines that I want to backup in away that I can restore to certain points in time.
From what I read Snapshot Replication achieves this (as opossed to back-up that clobbers previous results).
The main motivation is that if the data files are ransacked, and encoded, then if I just back-up I can end up in a state where the backed up files are also encrypted.

One way to do this is by using 2 Synology NAS machines where I can have:

• rsync processes to back-up files from multiple machines into a NAS1
• apply Snapshot Replication from NAS1 to NAS2

In this way, if the data is hijacked at certain point, I can restore the data to the last good state by restoring NAS2 to previous point in time.

I would like to know if:

• Snapshot Replication is the way to go, or there are other solutions?
• are there other ways to achieve Snapshot Replication, e.g. with single NAS?

I have an older Synology 2-Bay NAS DS213j.
Assuming that I buy a second, newer, NAS (e.g. DS220j), are the 2 NAS machines expected to work together?

Thanks

I'm upgrading rails from 4.2 to 5.0, and I'm getting some mean dependency issues. When I run bundle update i get the following output. The thing is that when i look through the messages, it looks like the gems should be able to install just fine when looking at the version requirements.

I also tried to delete my Gemfile.lock, that didn't help.

Any suggestions would be appreciated.

I am back again with my ctrlpanel application.

I have it 100% working in development and went through the process to get it loaded up to Heroku and got the app up, gems installed. DB is there (mostly) but I have an issue even before the DB. I am getting an error dealing with devise_invitable that I DO NOT get in Development. To my surprise I do get the same error when I launch production on my laptop which was shocking to me to say the least as everything works perfect in development. So I know it isn't a Heroku issue which I am happy about at least I can reproduce it. The full error is below here but the line that specifically deals with the error is:

I am more of a Java programmer and still somewhat new to development (2 years or so, can write Java code & web apps just fine) however the company I work for has 4 Rails applications and was asked to get this application working called CtrlPanel. I have been having to learn Ruby on Rails in order to help get this issue with this app fixed and get it working.

I have been working on this problem for over a week all day long every day and nothing I do is fixing it.

I fixed everything to the point the app comes up, web server runs serves the pages but all views are white screens as long as this application.html.haml file is present. I re-wrote the file with very basic bootstrap and it sort of works but nothing looks right. The problem seems to stem from 1 single like that simply says: = javascript_include_tag "application"

I have been all over the internet and have tried every single fix from changing coffee-script-source to v1.8.0 as I read Windows has an issue with newer rails and that file, I have tried every variation of changing it from application to default, and every type of ending you can think of no matter what I do it gives me this error message which I can not seem to find.

I am not even sure WHAT that line does, I assume it has to do with the new Google Maps API and I verified the key is valid and it was working before.

This is the error is it giving it says the line with "= javascript_include_tag" "application" giving error ExecJS::RuntimeError at / SyntaxError: [stdin]:1:1: unexpected //=

I am running a PC on Windows 10 20H2 x64 UEFI ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] Rails 6.1.3

(I did also install Ubuntu on another machine and it gives the exact same error, also gives the same error on another Windows machine)

The app is working IF I delete the "application.html.haml" file and put in a skeleton basic version all of the other views start working but of course none of them look right no menus no bootstrap no nothing.
Here is the application.html.haml file.

I have a project I'm trying to use ruby 3 (previously running with 2.7.2), but couldn't accomplish it.

After updated my gemfile with the ruby version and ran bundle, I'm receiving this error when trying to access rails c:
