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 am new to C++. I downloaded https://ftp.postgresql.org/pub/source/v13.1/postgresql-13.1.tar.gz from https://www.postgresql.org/ftp/source/ and unpacked it.

I created a new project in VS Community 2019. Added the example postgresql-13.1\src\test\examples\testlibpq3.c to the project.

Added my postgresql-13.1\src\include and postgresql-13.1\src\interfaces\libpq directories to "Include Directories" of the project.

Added Program Files\PostgreSQL\13\lib to "Library Directories" (this directory contains libpq.lib).

And when I try to compile, I get postgresql-13.1\src\include\postgres_ext.h(26,10): fatal error C1083: Cannot open include file: 'pg_config_ext.h': No such file or directory error.

I looked for the pg_config_ext.h in postgresql-13.1 directory. It's not there. Only postgresql-13.1\src\include\pg_config_ext.h.in.

Please tell me what am I missing? What's the easiest way to get the example to compile and run. Thanks in advance.

With the objective of implementing Rails 5.2.4, I just installed PostgreSQL 13 on a new SUSE 15.1 server, then Ruby 2.6.6, and I am now trying to install PostgreSQL client gem: pg version 1.2.3.

I first tried to run gem install pg, which claims for missing files pg_config and libpq-fe.h:

how do I make the selection with .in_ if it is integer? When I try to insert an integer, I get an error My column is array and integer.

I have a model with an Array field, and I'd like to find records where the last element of the field is greater than a known value. The array field will hold arrays of varying length.

I thought that using something like Test.select().where(known_value <= Test.array_field[-1]) for model {Test} would work, but that {-1} doesn't seem to work as expected. Here's a minimum working example:
