I can't show the contents of the db - I only get an bug report message

This is the message I get when I try to create an object from Posts.

" ..... edicate_builder/relation_handler.rb 1585 /Users/kitsco12/.rvm/gems/ruby-2.3.0/gems/activerecord-5.0.0.1/lib/active_record/relation/predicate_builder.rb 1586 /Users/kitsco12/.rvm/gems/ruby-2.3.0/gems/activerecord-5.0.0.1/lib/active_record/table_metadata.rb

It works fine otherwise. I can run the server. I can use commands, but when I try to show the contents (since we added "body:text" in this video) by typing: post = Post.all.

I've googled, but people are suggesting reinstalling Ruby. I don't think I need to do that, since ruby works fine. It's the db that seems to be the issue. I don't know how to fix it.

I tried everything. I tried "rvm gem pristine", reverted to the last working version. Tried to create another project just to make sure I didn't mess up the blog project.

The solution was plain and simple: Reboot the computer.

Same problem occurred when I run the command "bin/rails generate migration AddBodyToPosts body:text" and then "bin/rails db:migrate". My best guess is that it occurs when trying to add a new column in the database. Any ideas?

Your have to look carefully to to the error message displayed while trying to do rails db:migrate. Also, try to share the content of schema.rb and the most recent file under /db/migrate/.
