Basic Coding Projects

Projects for beginning coders, or if new to Python or web services

Easy Tickets

GCI

• Pick from these easy bugs for new Eden developers.

Feature Enhancements

• Fix UI issues, add features, provide user-requested enhancements.
  • You can pick from these feature requests.

• The landing page for each module is different -- some have descriptive text, others have statistics (a "dashboard"). Each has a different layout of menus.
  • Are any of these landing pages useful? What would be better for a typical workflow?
  • Make appropriate changes.
  • Is there a common sort of menu that would be useful?

CAP: Common Alerting Protocol

• BluePrintMessagingModule#CAP
• Complete the Model definitions that have been started in ​models/msg.py
• Think about some workflow for how this could be used

Common Operational Datasets

• ​http://oneresponse.info/resources/imtoolbox/publicdocuments/IASC%20Guidelines%20on%20Common%20Operational%20Datasets%20in%20Disaster%20Preparedness%20and%20Response%201%20Nov.%202010.pdf
• Complete the Model definitions that have been started in ​models/08_assess.py
• Think about how we could make use of them
  • Display on the Map
  • Have Reports which compare the baseline & situational assessments

Translations Admin Panel

Use Cases

• Admin wants to update /languages on their running instance with current version from Pootle
• Admin wants to be able to do offline translation of main language file(s) (either using native web2py UI or using a PO-based tool like Virtaal)
• Admin wants to be able to translate additional custom strings in this instance (either using native web2py UI or using a PO-based tool like Virtaal)

Tasks

• Add a page to controllers/admin.py to handle Translations.
• Update the InstallationGuidelines with any new optional requirements (such as translate toolkit).
• Gracefully give nice error messages if the translate toolkit isn't installed.
• Update UserGuidelinesLocalisation

Export PO file

• Dropdown to select which language
• Button to call ​web2py2po to convert the .py file to a standard PO file for the user to download

Import PO file

• Upload Widget which calls ​po2web2py onaccept to convert a .po file to a Web2Py .py file stored in the languages folder
  • Use the same filename prefix or prompt?
  • Do a merge

Update Pootle

Provide a set of admin scripts (bzr post-commit hook?) to update Pootle with any changed strings as a Merge.

GIS/Mapping

These are a various GIS/Mapping Tasks:

• Add a delay to the onHover tooltip (highlightControl)
  • Something like ​hoverIntent
• Continue Integration of ​Potlatch
  • for editing the main OSM database
  • for editing a local OSM database
• Make the display_feature() & display_features() popup a Window instead of opening in a DIV
  • This was working in FF before: http://eden.sahanafoundation.org/browser/views/sahana_scripts_min.html?rev=836#L39
• Replace the Measure Length/Area tools with ​GeoExt.ux
• Option to go Full screen & back
  • Full screen view (No Ext window) will be required for use on a small-screen, such as a Mobile device
• ​Layer Tree
  • Separate Overlays folder into Internal/External
  • Sub-folders of Overlays e.g. for:
    • Projects by Theme
    • Projects by Donor
• Get a pr/person/presence record upon login if HTML5 GeoLocation available & not changed since last time
  • login_next
• Map Preview when Lat/Lon set in pr/person/presence (auto or not)

Use the Mapping API to:

• Color coded maps according to Geo-data (threats, needs, etc)
• Placing variable sized markers on the map in proportion to data (number of people in camp, number of families needing food)

OSM Importer UI

• There is an import stylesheet for .osm files: static/xslt/import/osm.xsl
• This currently has hard-coded mappings between OSM admin levels & Sahana admin levels
  • * ​http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#10_admin_level_values_for_specific_countries
• A custom controller should be written
  • provide a UI to the user to select their country from the dropdown which pre-populates the mapping fields for manual verification/adjustment
  • process the results of this to pass new variables back to the stylesheet:
    • ​http://pub.nursix.org/eden/s3xrc/vita.modules.s3xrc.s3rest.S3Resource-class.html#import_xml

      resource = s3xrc.resource("gis", "location")
      template = os.path.join(request.folder, resource.XSLT_PATH, "osm", "import.xsl")
      resource.import_xml("uploaded_filename.osm", template=template, mynewvar="xxx")
      

• The Stylesheet needs updating to act on these vars when found

A nice further refinement would be to provide a UI to select a BBOX & optional filter to pull down the .osm file via ​XAPI

• Initially this could be manual text box entry of BBOX/filter
• Then add a Map-based BBOX selection & dropdowns for the filter (which prepopulate the real dropdowns for manual verification/amendment)

Recurring Requests

e.g. Shelter needs 100 liters of water/week

Want to be able to add Scheduling functionality to Requests.

There is a wrapper for Web2Py's Scheduler class in modules/s3/s3task.py

Can use UI ideas/code from Sync

Lat/Lon converter

Portuguese Volunteer Firefighters (Bombeiros) use Eden.

They get given Lat/Lon coordinates in Degrees/Minutes/Seconds, but Eden stores internally as Decimal degrees.

Tasks:

• Create a represent function to output the data as D/M/S
• Create a validator (& possibly widget) to allow entry of this format & have it converted to decimal dagrees for storage

Suggestion Box

Here are some potential features for a "suggestion box", roughly in order of priority:

• Text data entry form -- just use standard Eden database fields like "timestamp", "authorstamp", and "comments", maybe with a subject field.
• Allow defining topics or keywords. Let user choose a topic for their suggestion. Add all module names as an initial list of topics.
• Simple search in the body of posts -- match words.
• Regexp search.
• Allow commenting on (replying to) suggestions -- show comment thread with original post.
• Some form of importance rating (e.g. voting up or down).
• Original suggestion from: ​http://groups.google.com/group/sahana-eden/browse_thread/thread/bbda1e98b73e1437
