Wait for an update to complete and then retrieve the first row?

Questions

We have a wizard and a custom button which does some logic to determine the next step. The logic relies on an “errorModel” returning zero rows. The first step of the wizard allows the user to update the detailModel; the custom action should save the detailModel, update the errorModel, then retrieve the first row. If nothing is returned, the navigation will go to step4; otherwize the navigation will go to step3. Here’s my code: var $ = skuid.$; // retrieve the detail model var IQmodel = skuid.model.getModel(‘Intake Queues’); // save the detail model IQmodel.save(); // get the Errors model var errorModel = skuid.model.getModel(‘InvalidIQ’); errorModel.updateData({callback: function(){ var row = errorModel.getFirstRow(); // check if any Error records are returned var wizard = $(‘.nx-wizard’).data(‘object’); if(row==null) { // if true, navigate to step3 wizard.skooWizard(‘navigate’,‘step4’); } else { // if false, navigate to step2 wizard.skooWizard(‘navigate’,‘step3’); } } });

The challenge is that the detail model is successfully saved but the errorModel doesn’t complete the update in time for the decision on how to navigate. So even though after the update the model will return no rows (and should skip to step4) the wizard has already navigated to step3 by the time the errorModel completes its update.

One of my developers solved this: var $ = skuid.$; // retrieve the detail model var IQmodel = skuid.model.getModel(‘Intake Queues’); // save the detail model IQmodel.save(); // get the Errors model var errorModel = skuid.model.getModel(‘InvalidIQ’); errorModel.updateData(); errorModel.updateData(function() {callbackFunction(errorModel);}); function callbackFunction(errorsModel) { var row = errorsModel.getFirstRow(); // check if any Error records are returned var wizard = $(‘.nx-wizard’).data(‘object’); if(row==null) { // if true, navigate to step3 wizard.skooWizard(‘navigate’,‘step4’); } else { // if false, navigate to step2 wizard.skooWizard(‘navigate’,‘step3’); } };

Yeah looks like you solved it — the trick here is syntax. Our The save and updateData methods on Skuid Models have slightly different syntax for specifying a “callback” function to use after the asynchronous operations have completed. The syntax for each is described in our skuid.model API documentation, but basically it’s like this:

var contactsModel = skuid.model.getModel('Contacts'); var newRow = myModel.createRow(); contactsModel.updateRow(newRow,{ 'FirstName':'George', 'LastName':'Bailey' }); // // SAVE // contactsModel.save({callback: function(result){ // True if ALL rows saved were inserted, updated, and/or deleted successfully if (result.totalsuccess) { // Get the 18-digit Id of our new record console.log(newRow.Id); // Get the 15-digit Id console.log(newRow.Id15); // Show the entire record console.log(newRow); } else { // Otherwise, you can check out exactly what happened // with each DML operation, and respond appropriately console.log(result.insertResults); console.log(result.updateResults); console.log(result.deleteResults); } }}); // // UPDATE DATA (reruns the Model's query) // // Let's toggle a filterable Condition defined on our Model, // to just show Contacts in the USA, // then update our Model so that its query will be rerun var countryCondition = contactsModel.getConditionByName('MailingCountry'); contactsModel.setCondition(countryCondition,'USA'); contactsModel.updateData(function(){ // Lets see how many rows in our Model now console.log(contactsModel.data.length); });
