Using outdated gems introduces vulnerabilities to your Rails Applications. There is an easy way to find outdated gems using the Bundle Outdated command.

You have to be kidding me.. I just found out that Active Storage in Rails DOES NOT SUPPORT VALIDATIONS.

When I first began Ruby on Rails development, I was not able to use a LAMP stack. I was limited to working with the existing Microsoft IIS server.

I was working with some existing code where I needed to add an onclick javascript event.

I couldn’t even get an alert box to work. After a good bit of trial and error, I found the reason. I put in a line of radio button code from the www3 school’s try it and it worked. After closer inspection, I found that the original radio button had parenthesis.

This, of course, had to be done outside of Rails with Javascript/jQuery.

This one drove me nuts for a couple of hours. I needed to modify the contents of the user table in a rails app using rails console.

After a bit of trying it seemed that I was running the rails console in development mode. So, I tried the obvious rails console production.   After checking the tables, I found I was still in the development mode.

I needed to validate CSV files that were being imported into a Rails app. The validation was simple: Look for blank entries, ensure columns used for associations (IDs) were integers and check that certain other entries were numeric.

The first thing I checked was to make sure that the header of the CSV file matched what we expected. The simplest way to do this was to set an ‘expected header’ and then check the header on the CSV.
