Trying to set up and document a development environment

[funkymonkeymonk]

Hello thing devs,

Was trying to figure out how to set up a development environment. I've forked the repo and been documenting my efforts on the main branch of my fork.

I'm currently having an issue running the tests. I'm getting multiple errors based around btrsort. Below is an example:

     Failure/Error:
       @instances.each { |instance|
         cal.event do |event|
           instructable = instance.instructable
           prefix = []
           prefix << "Subject: #{instructable.formatted_topic}"
           prefix << "Instructor: #{instructable.titled_sca_name}"
           prefix << "Additional Instructors: #{instructable.additional_instructors.join(', ')}" if instructable.additional_instructors.present?
           prefix << "Material limit: #{instructable.material_limit}" if instructable.material_limit
           prefix << "Handout limit: #{instructable.handout_limit}" if instructable.handout_limit

Can you offer and assistance in getting this set up? My current guess is my version of postgres is possibly to new. What version of postgres are you using on the server?

Also happy to set up a PR to work out of it it's easier to communicate there.
