[lvachon1]

Scope

Asana Ticket: ⛴️ 💸 Update ferry fare cards

Implementation

• Updated the reduced price fare
• Added the new zone 1a fare card data
• Cloned the ferry_inner_harbor fare entries into ferry_charlestown will remove the old entries once the content is updated.
• Re-updated the reduced price fares, hopefully the right way this time

Screenshots

I'm doing a bit more digging to see if I can help find more actionable feedback here, but this change is causing the ferry fares page to crash with 👇 stack trace:

The crash is cache-dependent, so in order to reliably reproduce it, you need to run 👇 in an iEX shell while on your branch.

iex> Dotcom.Cache.Multilevel.flush

Issue (blocking): I'm not entirely sure what this field is for, but the page crashes unless this is set to nil or omitted 😵‍💫

[lvachon1]

I just found the same thing... nil it is!

[joshlarson]

To embellish a bit, I don't know what the field is for, but I do have a sense of why this change is causing the page to crash:

• LiquidObjects.Fare.get_fares/1 makes a call to Fares.Repo with a set of default (overridable) arguments
• Those default arguments include reduced: nil, which means that this entry, with reduced: :any, won't match.
• That causes fare to be nil in the fare card template, which then causes the stack trace above when we try to query fare.mode a few lines down.

---

Changing reduced back to nil does fix the crash... I have no idea if there's a more elegant or correct way though.

Heh - I wrote ☝️ whole thing before I saw that you replied 😅
