QUESTION
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.
ANSWER
Answered 2021-May-04 at 18:59I did finally figure out what this was.
The older versions of rails in this case v4.2.1 used the javascript_include_tag for the line that deals with application:
= javascript_include_tag "application"
In the newer versions of rails in my case v6.1.3.1 you have to use javascript_pack_tag
= javascript_pack_tag
This solved the issue and the views all started working. I did mention above I was working on a PC running Rails v6.1.3; however I noticed I didn't make it clear that I was also having to upgrade this program from Ruby v2.2.2 and Rails v4.2.1 to Ruby v 2.7.2 and Rails v6.1.3, that might have helped to have made that more clear. Apologies if that confused anyone. I am still VERY new to Rails and using StackOverflow.com. I am happy to report I have only 1 single issue left on this program and the rest of the program is all working properly. I will be posting another question in fact because the last issue deals with a complicated scope query and it uses different syntax again due to the newer version of rails and I haven't been able to figure it out. In any even if you are running an older version of Rails and you are trying to get the program to work on a newer version (my case as I couldn't get rails v4.2 to run or work on ANYTHING, PC, Linux nothing) then you have to change the include_tag to a pack_tag. I do not pretend to say I fully understand why. I know it has to do with webpacker but beyond that I am still learning Rails. Perhaps someone with more knowledge than myself can shed some insite as to why the syntax changed. Oh and in addition the line ended up needing to read as follows:
= javascript_pack_tag "application", "data-turbolinks-track": "reload"
I didn't have the turbolinks reference either.
I hope this helps someone else in a similar situation that I was in, it was not easy to find. I only discovered it when I went through some tutorials on making other generic apps and saw the difference on that line.
QUESTION
Is there any way to cause Sinatra to transparently handle cached data correctly that was written by Rails, eg, to implicitly handle the ActiveSupport class that Rails uses when it stores data?
A Heroku-hosted Rails 4 app and a Sinatra app used a shared Memcachier store to share certain ephemeral data.
If a key/value is created on Sinatra, everything works normally:

I am using ruby 2.3.3 and Rails 4.2.8 with Puma (1 worker, 5 threads) and on my admin (i.e. not critical) page I want to show some stats (integer values) from my database.

QUESTION
I have a Rails 5.2 app hosted on Heroku with Memcached cloud used, I have implemented multiple caching techniques in the app but one part of it has been very problematic & I tried to fix it for the past few days:
Fragment caching in one view had a design issue that I have fixed & then this design bug is still cached & delivered to users even after clearing the cache multiple times using:
Rails.cache.clear which gives me a correct output of clearing the cache like this:
ANSWER
Answered 2019-Aug-20 at 11:30Instead of expiring fragment caches, I'd recommend versioning them. e.g. instead of nav_header, you use a key like nav_header_v2. Memcached will automatically clear content that doesn't get used, so the original fragments disappear to make room for the new ones. You never have to worry about clearing the cache.
You can go even further and automatically include a git version ID on all fragment keys, so they'll refresh when the code changes, e.g. nav_header_#{My::Application.config.git_commit}|.
This is the approach RailsGuides explains and ActiveRecord supports it via cache_key_with_version, so you can easily fragment-cache views of your models without having to clear them when the data changes.

I'm doing this upgrade for the first time and I'm facing problem on very first step :-(

...ANSWER
Answered 2018-Nov-11 at 15:42First, as ThorTL67 noted in the comments, it is a good idea to update your Rails version incrementally, not in one big leap. That way, your dependency issues will be less complex.
Check what version of Bundler you are using by running bundle version. If that version is old, it might be that some dependencies are not correctly calculated, and it might help to update Bundler (gem update bundler).
Then to the steps you can take to update from 4.2 to 'some higher version'. The list of errors that you got shows the conflicts between gem dependencies. You can try and tackle these conflicts one by one.

Answered 2019-Apr-12 at 04:07You need to upgrade your postgres_ext gem.
You currently have Arel 4.0.2 instead and PostgresExt 2.0.0 installed.
I see that PostgresExt 2.1.3 says “Fixes Arel 4.0.1 issues”. https://github.com/DavyJonesLocker/postgres_ext/blob/master/CHANGELOG.md#213
Your version of PostgresExt is incompatible with the version of Rails you have installed. I came to this epiphany because of the stacktrace you recently added.
