Modificar accés app mòbil#361
Conversation
|
|
El QR servia per controlar la creació dels usuaris responsables de l'alumne. |
|
Un dels objectius de l’app era no dependre del mail. Si l’usuari perd la contrasenya (i el usuari), per exemple, perquè canvia de mòbil, com ho fa el tutor per fer-li arribar un nou sistema d’accés? Amb el QR la idea era que el tutor l’imprimia i la familia des de l’app s’escanejava. Era el sistema que vam pensar per substituir usuari/contrasenya. Segurament no era el millor sistema del món :) |

Pull request overview
Aquest PR elimina el flux d’accés a l’app mòbil basat en QR i adapta el backend perquè l’accés es faci amb usuaris “responsables” (i alumnat major d’edat), ajustant també notificacions i rutes de l’API.
Changes:
- Eliminació de la funcionalitat QR (models, vistes, urls, serializers i taules associades) i actualització del menú.
- Adaptació de l’API de l’app mòbil per operar amb
alumne_idi incorporar consultes d’alumnes associats a un responsable. - Ajust de notificacions/portal perquè els responsables no rebin notificacions ni puguin accedir a dades d’alumnes majors d’edat.

- The notification workflow doc still references
QRPortal.novetats_detectades_moment, but QRPortal has been removed and notifications now appear to be tracked viaNotifUsuari/notificacions_familia. Please update this section (and any referenced dependencies likeqrcodeinrequirements.txt) so the documentation matches the new implementation.
### Workflow Notificacions
* El procés **notifica** de **relacioFamilies** actualitza el camp **novetats_detectades_moment** del model **QRPortal** quan detecta que hi ha novetats a informar a la família.* L'aplicació fa pooling demanant si hi ha novetats (fem pooling per evitar usar serveis de tercers de push)
* La part servidora anota la data en que li ha enviat a la família les dades.

- This migration was modified to remove its original schema operations. Editing already-published migrations is unsafe: environments that previously applied 0011 will not drop the QRPortal table, while new installs will never create it, causing schema drift and making historical migration state unreliable. Please revert this migration to its original contents and add a new forward migration that properly removes the model/fields (e.g.,
DeleteModel,RemoveField) with any needed data cleanup.

EsUsuariDeLaAPI.has_permission currently assumes request.user.responsable exists and will raise an AttributeError for non-responsable users (e.g. professors or almn* users). Also, alumne_es_major_de_18 is computed from the requested alumne_id, which would allow any authenticated user to access any alumne ≥18 by guessing the id. Consider using getRol(request.user, request) and enforcing: (1) responsables can only access alumne_id in responsable.get_alumnes_associats() (and only if the alumne is <18 per requirements), and (2) almn* users can only access their own alumne_id and only if they are ≥18; return False on missing/invalid alumne_id.

alumnes_associats is only protected by IsAuthenticated but then unconditionally calls responsable.get_alumnes_associats(). For non-responsable authenticated users this will crash (500). Consider restricting this endpoint to responsables (via a dedicated permission or an explicit getRol check returning 403) before accessing responsable.

usuaris_app_associats was removed from AbstractAlumne, but there are still runtime references to this field elsewhere (e.g. aula/apps/extEsfera/sincronitzaEsfera.py and aula/apps/extSaga/sincronitzaSaga.py call a.usuaris_app_associats.set(...)). Without updating those call sites (or providing an alternative association mechanism), imports/sync jobs will crash with AttributeError.

If the database has no users, admin_user will remain None and new_activity.credentials = (admin_user, True) can break downstream signals/permission logic expecting a real user. Consider explicitly failing with a clear message when no suitable user is found (or creating a dedicated service user) before entering the transaction loop.

Alumne.objects.get(id=alumne_id) will raise Alumne.DoesNotExist and return a 500 if an invalid/removed alumne_id is requested. Since alumne_id is user-controlled (URL param), consider using get_object_or_404 or catching DoesNotExist and returning a DRF validation error/404 response.

Sortida doesn’t define a descripcio field (it’s programa_de_la_sortida), so assigning new_activity.descripcio just adds an in-memory attribute that won’t be persisted and can confuse future readers. Also new_activity.estat is assigned twice; please remove the dead assignment and keep a single, intentional source of truth (copy original vs reset).

This script sets a hard-coded password (djau) and activates accounts for both students and responsables. If accidentally run outside a controlled demo environment, this is a serious security risk. Consider adding an explicit safety guard (e.g., require settings.DEBUG or an environment variable confirmation) and/or generating random passwords instead of a fixed one.

Només es creen els usuaris responsables si s'informa de les seves dades personals. Si un alumne major d'edat no informa d'aquestes dades, aleshores no hi ha cap usuari responsable.
Si l'alumne ha informat de les dades personals dels seus pares, doncs hauríem de deixar que els pares puguin accedir encara que sigui major d'edat. L'alumne sempre té l'opció de demanar que esborrin les dades dels seus pares i passaria a ser l'únic usuari.
No limitaria l'accés segons aquesta proposta.

El migrations antics s'han de quedar tal qual.
S'hauria de fer "makemigrations".
No limitaria l'accés dels responsables a alumnes majors d'edat, l'alumne major d'edat sempre té l'opció de no proporcionar les dades dels pares o demanar que siguin esborrades.

@amorilla té raó que no es pot modificar la història dels migrations.
Moltes gràcies per les aportacions!!!! |
Amb la nova possibilitat de que l'alumnat tingui usuaris associats ("responsables"), desapareix la necessitat d'utilitzar els QR's per donar seguretat en l'accés a l'aplicació mòbil.
