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
Changes: - Add CommunityFridgeLive.Index and FormComponent with routes for /community_fridges, /community_fridges/new, and /community_fridges/:id/edit - Add "Community Fridges" entry to the sidebar navigation (archive_box icon) - Relax CommunityFridge changeset to not require location_id at the UI level (name is the only required field; location association remains constrained at the DB level via assoc_constraint) - Add LiveView tests covering list, create, validate, edit, direct navigation, and access control (non-dispatchers redirected to /login)
Replaces the plain "Photo URL" text input with a drag-and-drop upload widget backed by LiveView's file upload primitives and MediaStorage. - mount/1 registers a single-file upload slot (:photo, gif/png/jpg/jpeg) - Save handler calls consume_uploaded_entries → MediaStorage.upload_file! and injects the returned URL into params; falls through unchanged when no file is selected so the hidden input preserves the existing photo - cancel_upload event removes a pending entry before save - Template shows existing photo preview (with hidden input to preserve it through form submits), drag-and-drop zone with live_file_input, pending entry preview via live_img_preview, and per-entry error display Tests cover: existing photo renders in edit form, dropzone markup is present, pending upload preview appears after file selection, and cancel removes the preview.

Summary
Adds a dispatcher-facing Community Fridges management section — a full CRUD interface for neighbourhood food-sharing locations, accessible from the sidebar. Dispatchers can list fridges, pin them on a map, create and edit fridge details, associate a street address/coordinates via the existing
LiveLocationcomponent, and upload/remove a cover photo.closes #[ticket]
What changed
Schema & context (
CommunityFridge,Locations)Location is now optional.
Previously the schema required
location_idviavalidate_requiredand enforced referential integrity withassoc_constraint(:location). This PR removes both — a fridge can be created or edited without a location, making it easier to draft a fridge entry before its address is confirmed.Switched from bare FK to nested association.
cast(params, [..., :location_id])is replaced withcast_assoc(:location), so the form submits full nested location params (address, coords, etc.) through the existingLiveLocationcomponent rather than a raw integer ID.Eager loading moved into queries.
Both
list_community_fridges/0andget_community_fridge!/1now preload:locationinline using Ecto'spreload/2query macro rather than a separateRepo.preload/2call after fetch. This avoids a second round-trip to the database and follows the pattern used elsewhere in the codebase.get_community_fridge!/1is also converted fromRepo.get!/2to a query pipeline (where+Repo.one!/1) to make the preload composition natural.Struct initialisation for
cast_assoc.create_community_fridge/1now initialises the struct as%CommunityFridge{location: nil}rather than a bare%CommunityFridge{}. This tells Ecto the:locationassociation is explicitly absent (not just unloaded), socast_assocknows it should insert a newLocationrecord when location params are provided.LiveView — Index (
CommunityFridgeLive.Index)List / Map toggle.
A segmented button in the top-right of the page switches between a sortable table and a Leaflet map. The active tab is tracked in socket state as
:mode(:listor:map). Switching to map pushes aleaflet:redraw_mapevent to force Leaflet to re-render after the container becomes visible (it needs a trigger because the map div is hidden while in list mode).Map markers.
fridge_markers/1builds a layer list for every fridge that has a non-nil location with valid coordinates — rendered as a warehouse-icon marker in Bike Brigade blue (#1c64f2) with the fridge name as a tooltip.map_center/1centres the initial view on the first fridge that has coordinates, falling back to Toronto City Hall (-79.3832, 43.6532) when no fridges are mapped yet.Routing as live actions.
All three routes (
:index,:new,:edit) share the same LiveView module.handle_params/3delegates toapply_action/3which sets the relevant socket assigns. On:indexit also refreshes the fridge list and recomputes map layers, so the list stays current after a create or edit.LiveView — Form Component (
CommunityFridgeLive.FormComponent)Fields.
Name (required), description, location (via
LiveLocation), active flag, pair-preferred flag, and photo.Photo upload.
Uses
Phoenix.LiveView.Uploadwith a drag-and-drop zone, file picker, client-side preview vialive_img_preview, per-entry cancel, and a delete button for photos that are already saved. On save,consume_uploaded_entries/3uploads toMediaStorageand injects the returned URL into params. When no new file is uploaded and the existing photo field is an empty string (what the hidden input sends when cleared), it is normalised tonilbefore the changeset is built.Validation.
The form sends a
"validate"event on every change, building a changeset withaction: :validateso inline errors appear immediately without requiring a submit.Navigation.
Both
:newand:editpaths usepush_patchon success so the parentIndexLiveView stays alive andhandle_paramsre-runs to refresh the list. The Cancel button uses anavigatelink which does a full LiveView navigation back to the index.Routing & navigation
Three routes added under the existing dispatcher-only
require_dispatcherpipeline:A sidebar entry is added between Riders and Stats using the
archive_boxHeroicon. The:community_fridgespage key is added to thecurrent_pageallowlist inLayoutsso the sidebar link highlights correctly when active.Seed / fixture fixes
srid: 4326onGeo.Point.Toronto.random_location/0was buildingGeo.Pointstructs without an SRID. PostGIS requires matching SRIDs for geometry operations, and thegeo_postislibrary serialises a nil SRID as0, which caused constraint and comparison failures in tests. Addingsrid: 4326fixes this and aligns with how location coords are stored elsewhere.fixture(:community_fridge)updated.Previously the fixture inserted a
Locationrow first and passedlocation_id:(a bare FK). It now passeslocation:as a nested atom-keyed map fromToronto.random_location/0, which goes throughcast_assocand inserts the location as part of the fridge creation. This avoids an extraRepo.insert!in every test that just needs a fridge with a location, and keeps the fixture aligned with the actual form code path.Tests
CommunityFridgeLiveTest(13 tests, new file):Covers the full dispatcher workflow — listing fridges, address column display, map tab toggle, create with nested location params, name validation, edit, direct edit URL navigation, field value preservation in the edit form, photo display in edit, upload dropzone rendering, upload preview on file select, upload cancel, and access control (riders redirected to
/login).CommunityFridgeTest(unit, updated):Removed the
setupblock that inserted aLocationto get an ID — tests now pass inline nested location maps directly to the changeset. Added a new integration test asserting thatupdate_community_fridge/2mutates the associatedLocationrecord in-place: thelocation.idstays the same after update whilelocation.addressreflects the new value, confirmingon_replace: :updateis working.LocationsTest(updated):Create and update assertions now use pin-pattern matching on a destructured map (e.g.
^name,^active) rather than manual variable assignment, making the intent clearer. Removed theupdate_community_fridge/2 with invalid datatest which compared the returned struct to the original using==— this was fragile after the preload change and the meaningful validation coverage is already handled at the changeset unit level.CampaignLiveTest(updated):Corrected the hardcoded
srid: nilin@default_locationtosrid: 4326to match the seed fix and avoid a geometry serialisation mismatch in the existing task creation test.Summary by CodeRabbit
