Here’s the approach we’re using that builds on the approaches above, but the code is parameter driven and reusable. We use a UI only model that generates a row on load and has a field with default values for a pollModel, an updateModel and an interval (in seconds) (see Screenshot). Then there is a Model action when a row is created it runs the snippet below. The argument passed into the snippet is the row created when the model is loaded.

Here’s the snippet:

var params = argumentsu0],

$ = skuid.$;

pollmodel = params.row.PollModel;

updatemodel = params.row.UpdateModel;

pollinterval = params.row.Polling_Interval;

checkModel = skuid.$M(pollmodel);

updateModel = skuid.$M(updatemodel);

$(function(event){

// THe names of the Models that should be checked every so often for updates

// These should NOT be the Models associated with Charts / Tables, etc.

var RECENT_UPDATES_MODELS = E

pollmodel

];

// Each of our Models should have a Condition named “LastModifiedDate”

var COMMON_CONDITION_NAME = “LastModifiedDate”;

var milliseconds = pollinterval * 1000;

var RecentUpdates = $.map(RECENT_UPDATES_MODELS,function(modelId){ return skuid.$M(modelId); });

setInterval(function(){

var now = new Date();

var previous = new Date(now.getTime() - milliseconds);

$.each(RecentUpdates,function(i,model){

var condition = model.getConditionByName(COMMON_CONDITION_NAME,true);

var sfDateTime = skuid.time.getSFDateTime(previous);

model.setCondition(condition,previous);

});

$.when(skuid.model.updateData(RecentUpdates))

.done(function(){

var foundModelWithUpdates = false;

$.each(RecentUpdates,function(i,model){

if (model.getRows().length) {

foundModelWithUpdates = true;

}

});

if (foundModelWithUpdates) {

var modelsToUpdate = ;

if (checkModel && checkModel.getRows().length && updateModel) {

modelsToUpdate.push(updateModel);

}

$.when(skuid.model.updateData(modelsToUpdate))

.done(function(){

//Placeholder for future post update actions

});

}

});

},milliseconds);

});

FYI, the original source for this script was modifying this solution:  https://community.skuid.com/t/real-time-dashboards, which has the full XML for the page.

The example opportunity dashboard uses an inline resource, and we converted it to a snippet that we can invoke more dynamically.  We use a lot of page includes in our site and have found that snippets are way more reliable than in-line code when the DOM is swapping around and loading in different sequences.  If I were to make one tweak, it would be to pull the filter field (i.e. LastModifiedDate) into the UI Model and use it as a parameter in the javascript.  That way all the business logic would be outside the code.
