pre DI template

Full template to make DI dashboards easily with public maps/datasets.

Named maps need a diferent piping and are not this straightforward.

Tips:

• Add widgets to layer #1, using the options described here

myapp.addWidget('category', 1, {
  "title": "Metro line",
  "column": "closest_metro_line",
  "aggregation": "count"
})

• Add a custom widget(mywidget) in position 0 of the widgets container like:

myapp.wcontainer.insertBefore(document.querySelector('#mywidget'), myapp.wcontainer.children[0]);

where the widget is defined in the HTML like

<div id='mywidget'>
    <div class="CDB-Widget CDB-Widget--light">
        <div class="CDB-Loader"></div>
        <div class="CDB-Widget-error is-hidden">
            <button class="CDB-Widget-button CDB-Widget-errorButton js-refresh"> <span class="CDB-Widget-textSmall CDB-Widget-textSmall--bold">REFRESH</span> </button>
        </div>
        <div class="CDB-Widget-body">
            <div class="CDB-Widget-header js-header">
                <div class="CDB-Widget-title CDB-Widget-contentSpaced">
                    <h3 class="CDB-Text CDB-Size-large u-ellipsis js-title">Title</h3>
                    <br>
                </div>
            </div>
            <div class="CDB-Widget-content">
                Content
            </div>
        </div>
    </div>
</div>

It will be visible only if there is at least one native widget present

• Add new layers like:

vis.map.createCartoDBLayer({
      "type": "CartoDB",
      "cartocss": "#populated_places{marker-fill-opacity: 0.9;marker-line-width: 0;marker-line-opacity: 1;marker-placement: point;marker-type: ellipse;marker-width: 2;marker-fill: #FFFFFF;marker-allow-overlap: true;}",
      "sql": "select * from populated_places"
    });

• Get/Set the query or the styling of the layer #1 like:

var mysql = myapp.layers[1].get('sql');

myapp.layers[2].set('cartocss', '#spain_census2011{
  polygon-fill: #FF6600;
  polygon-opacity: 0.7;
  line-color: #FFF;
  line-width: 0.5;
  line-opacity: 1;
}')

• Get/set the available params for a given widget (view / model):

// get
myapp.widgets[1].get('attrsNames')
myapp.widgetsdata[1].constructor.ATTRS_NAMES

// set
myapp.widgets[1].update({"prefix":" meters"})
myapp.widgetsdata[1].update({"bins": 25})

• Get the available events for a given widget (view / model):

Object.keys(myapp.widgets[1]._events)
Object.keys(myapp.widgetsdata[1]._events)

• Get/Set the selected bins of a given histogram/time-series widget

// get
myapp.widgetsdata[4].filter.get('min')
myapp.widgetsdata[4].filter.get('max')

// set
myapp.widgetsdata[4].filter.setRange(min_val,max_val)

• Get/Set the selected categories of a given category widget

// get
myapp.widgetsdata[4].filter.acceptedCategories.toJSON().map(function(a){return a.name})

// set
myapp.widgetsdata[4].filter.accept(["Arts", "Education and Society"]);

• In category widgets, the aggregation column param should be aggregation_column instead of aggregationColumn to work.
