I’m actively engaged in greenfield development once again and I’m learning / relearning things that I likely have known in the past. I don’t know if this is a known issue, a bug or maybe a design choice. Either way, I found it useful to know this so I thought it was useful to document it.

I spend a lot of time in rails console (thank you Jared for beating this into me a thousand, thousand years ago; hope you are well) and reload! normally works pretty damn well but this one caught me hard. Take a look at this back trace

link = FactoryBot::create(:link)

  Account Create (0.2ms)  INSERT INTO "accounts" ("email", "status", "role") VALUES ($1, $2, $3) RETURNING "id"  [["email", "howard@watsica.com"], ["status", "verified"], ["role", "customer"]]
  Account::PasswordHash Create (0.2ms)  INSERT INTO "account_password_hashes" ("id", "password_hash") VALUES ($1, $2) RETURNING "id"  [["id", 63], ["password_hash", "[FILTERED]"]]
  TRANSACTION (0.5ms)  COMMIT

Note: All of this was done in test mode on rails console or:

RAILS_ENV=test bundle exec rails c

Here is what’s going on:

  1. I start by trying to create a FactoryBot object which had an error.
  2. I made some changes in the class (not shown; offscreen).
  3. I did a reload!
  4. I tested again – failure.
  5. Step #2 all over again.
  6. I started to think that maybe I needed to exit – that reload! wasn’t working.
  7. I exited and MAGIC – it worked

The error above was that I was missing the belongs_to block in my model:

belongs_to :account
belongs_to :project
belongs_to :team
belongs_to :link_type

I suspect this is a pretty common error when starting a new project.
