Vn/community fridge crud v1 - #510
Conversation
Introduces the CommunityFridge schema, migration, and test fixtures as the first step of the community fridges feature.
The cubic-dev review suggested supporting a `location:` key in fixture(:community_fridge, ...) so callers can pass a location struct directly, matching the pattern used by rider and campaign fixtures. Implementing this requires fixture(:location) to persist a Location record and return a struct with an id, rather than returning a plain map as it does today. That change affects every fixture and test that currently calls fixture(:location), so the blast radius is wider than this PR's scope. The improvement will be handled in a follow-up PR dedicated to normalising the location fixture across the test suite.
Add unique_constraint(:location_id) to CommunityFridge.changeset/2 so a location cannot be associated with more than one community fridge. The has_one relationship does not enforce cardinality at the database level, so this constraint surfaces duplicate-location errors as changeset errors. Also trim the minimal-attributes changeset test to focus on required fields rather than default values.

- Add `persisted_location` fixture that inserts a Location into the
database
(complements existing in-memory `location` fixture)
- Add `community_fridge` fixture that lazily creates a persisted location
and
handles required location_id association
- Add LocationsTest with full coverage of community_fridge operations
- Use setup block to eliminate fixture repetition across tests
- Use pin operator (^) in pattern matches to validate update attrs without
assertion repetition
- Enable async: true for parallel test execution

Reject null values for both boolean fields.
When an existing fridge receives %{active: nil} or %{pair_preferred: nil}, this changeset remains valid. Ecto accepts explicit nil during casting; schema defaults do not replace it. (raw.githubusercontent.com)
Both columns are null: false in priv/repo/migrations/20260825183237_add_community_fridges_table.exs, Lines 9–10. The update therefore raises a database error instead of returning {:error, changeset}. The unique and association constraints do not handle NOT NULL violations. (raw.githubusercontent.com)
Add :active and :pair_preferred to validate_required/2. This rejects nil while accepting false and the existing defaults. Add focused create and update tests with otherwise valid attributes and one null boolean at a time. (hexdocs.pm)
