I am having trouble with how to create a two-column bulleted list using prawn PDF and prawn/table. I wanted to know if there is a way to do it that's not too custom/uses existing classes to take care of overflow to a new page, etc so I don't miss things or reinvent the wheel.
I want the list to look something like this:
*Name 1 * Name 3
*Name 2 * Name 4
Currently what I have is:...

Alright so I ended up using the table method, I'm not sure why I didn't think of this earlier but we can just split the list of names in half and append them in such a way that the second half of names is appended to the same row as the first half of names. Here is essentially what I did:
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 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.
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 did finally figure out what this was.
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:
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.
In my view method, my selected dropdown like this. My problem are:-

How about this:
CashTransaction model I've got default scope:
ANSWERAnswered 2021-Jan-27 at 08:17
default_scope is probably one of the worst part of Rails and should be avoided at all costs.*
You can just create a custom scope if you have some special ordering you do often.
I create a table of cash transactions inside of PDF using Prawn gem. To do so I iterate through the Hash with
parsed_cash_transactions but before each is started I need to save the
last_item of that Hash to check when I should display the summary table below the main table.

You could indeed use a guard clause, although it is not the most pretty, since it condition is pretty long.

I'm using Ruby for scripting, and Prawn-labels to print ISBN labels for books, using Barby to generate the EAN-13 bar codes.
The ISBNs come out of MySQL. That works fine. I can create a PDF of 30-up labels containing the titles of the books, using Prawn/labels. That works fine.
However, I am not having much joy putting a Barby-generated PNG image of the proper EAN-13 barcode on the label.
Here's getting the info out of the database and generating EAN-13, pretty straightforward:...

pdf.image(png) instead of
pdf.embed_image. This is a wrapper around
pdf.embed_image that does the necessary work of getting the necessary data out of the PNG file.

stroke_horizontal_line expects the third argument to be a hash. You need to include the key before the data.
