Protractor - How to get actual values from the Repeater, not the Elements?

Question

I am creating a Protractor script to test my quiz game that puts up random questions and answers, so I need my script to be able to figure out which answer is correct, so I can click it.

I can't figure out how to get the values directly from the model, instead of elements, since correct/incorrect is not exposed as an element on the page.

The model provides the answers in Choice in Question.Choices, and I need to find the Choice where Choice.IsCorrect is true. How do I get access to this value?

I wouldn't use the element() function, right?

element(by.repeater('Choice in Question.Choices').row(0).column('Choice.IsCorrect'))

The idea is to use element.all() in conjunction with filter() and evaluate():

var correctChoices = element.all(by.repeater('Choice in Question.Choices')).filter(function (elm) { return elm.evaluate('Choice.IsCorrect').then(function (value) { return value; }); });

As a result correctChoices would contain elements where Choice.IsCorrect is truthy.

If you need to get an array of values for the correct choices, use map() and getAttribute():

correctChoices.map(function (elm) { return elm.getAttribute('value'); });

or, if you need texts make use of getText():

correctChoices.map(function (elm) { return elm.getText(); });
