Allow person entities (people, groups, organisations) to save a search and be notified when the results change.
In an event of disaster, this functionality would help a lot in terms of providing information (take the example of dissemination of information related to availability of food, shelter, hospitals etc.). The project's essential capability is to disseminate information about various aspects through various means such as email/twitter/sms. Integrating this service into a Sahana Eden system will add to the platforms' capability of tackling various issues faced in emergency/disaster management.
A single model for holding information about the search query and the parameters that are saved by the user. This will be in
/modules/eden/pr.py as a component of
- Name of the saved search as specified by the user.
- The person entity to be notified when the search results change. Defaults to the pe_id record associated with the current user account.
- The query string for the search.
- Format for the notification, either a list (default), map, report, graph (this is a report).
- Subscription mode, e.g., email (default), Twitter, SMS.
- How often the search is checked for changes, e.g., never (default), every 15 minutes (not hourly?), daily, weekly and monthly.
The date and time the search was last executed by the subscription method. Set to match
modified_onwhen record is first created.
Public Saved Searches
- The saved search to make public.
Each search page will have a widget the user can activate to save the current search. They will be directed to a new page where they can type a name for the search.
Saved Search List
Each person entity has a component for saved searches. This page will list all searches saved for this person entity, displaying the name of the search (as defined by the user when it was saved) and the query parameters.
(The any/all option will require special extraction)
Query parameters will be displayed as human-readable definition lists, e.g.:
- Search Organisations (?)
- search strings
- Red Cross / Red Crescent
- Food Security
- Home Country
- New Zealand
The user will have three options for each search record:
- run executes the search
- edit allows the user to edit the saved search record
- delete deletes the saved search record
