Hand-craft visualization of lettuce datasets

[jjmata]

The GeoJSON datasets are pretty much ready: one, two, three (we have something we can work with already, but @ivanprado is going to re-run the holes one to get us better accuracy), so the idea is to:

• complete the "multiple basemap" trick from Allow visualizations to present multiple tiled raster layers #1
• import three (more?) layers: lanes, holes, fields
• add a widget that calculates de estimated number of lettuces per "field"
• improvise and add a few other widgets
• improvise and add a heatmap of holes

Did I miss anything as discussed, @apercas or @ivanprado?

I didn't want to check them out but we have already imported the lanes, holes and fields dataset and we can add a heatmap with the holes with no effort.

The widget issue that is driving me crazy in detail is:
How to reproduce:
-Both locally or on alpha: Add a widget (whichever you like)
-Try to display it
Cause:
-Failing while routing (for some reason the http://tileo.localhost/ becomes http://dev.localhost.lan:8181)
Where to see it:
-Check the right hand column
Status:
-I first checked the app_config YAML file so it matches the preferred route. It didn't change anything at all (meaning: it changes the regular route but for this bug it did't apply).
-I started debugging using Chrome DevTools adding a breakpoint in the XHR and then scaled up until I spotted URL change itself on model-updater.js L166:

var dataviewMetadata = windshaftMap.getDataviewMetadata(dataviewModel.get('id'));

-I checked the Windshaft config and the output there and both are correct
-I couldn't test it but my guess is that the content of each item of the DataView collection is wrong (meaning, poor URL) from the its creation.

I found the reason for the widget issue*, it's a missing configuration value as we suspected (a new one that we are missing) on the Windshaft side. It dates back to November (so recent in the grand scheme of things), here is the commit:

• CartoDB/Windshaft-cartodb@488698d

And the historical background directly from @rochoa's mouth :-)

• Subdomainless awareness CartoDB/Windshaft-cartodb#493
• Allow to set resource URL templates with substitution tokens CartoDB/Windshaft-cartodb#594

(*) I didn't step into it via debugger, but I believe the fallback URL was being assembled here.

This was accomplished and demo'ed to Grupo Gs a few days back. Closing.
