[Falcor] Retrieving Multiple Values
In addition to being able to retrieve a path from a Falcor Model, you can also retrieve multiple Path Sets. Path Sets are paths that contain ranges or multiple string keys inside of indexers. In addition to being able to retrieve a Path Set, you can also retrieve as many paths as you like in a single method call.
You can fetch range of data:
model.get('people[0..1].titles[0].name')
Because what you fetch is not just a single a value, you need to use:
model.get()
Which return you a json string.
SO for example:
<!-- index.html -->
<html>
<head>
<!-- Do _not_ rely on this URL in production. Use only during development. -->
<script src="//netflix.github.io/falcor/build/falcor.browser.js"></script>
<script>
var model = new falcor.Model({
cache: {
people: [
{
name: "ZT",
titles: [
{
id: 123,
name: "Senior Frontend developer",
rating: 10
}
]
},
{
name: "WO",
titles: [
{
id: 321,
name: "Senior Software Engineer",
rating: 10
}
]
}
]
}
}); model.get('people[0..1].titles[0].name')
.then(function (json){
console.log(JSON.stringify(json, null, 2));
});
</script>
</head>
<body>
</body>
</html>
And what you will get:
{
"json": {
"people": {
"0": {
"titles": {
"0": {
"name": "Senior Frontend developer"
}
}
},
"1": {
"titles": {
"0": {
"name": "Senior Software Engineer"
}
}
}
}
}
}
You can pass multi enter points:
model.get('people[0..1].titles[0].name', 'people[0..1].titles[0].rating')
So you will get :
{
"json": {
"people": {
"0": {
"titles": {
"0": {
"name": "Senior Frontend developer",
"rating": 10
}
}
},
"1": {
"titles": {
"0": {
"name": "Senior Software Engineer",
"rating": 8
}
}
}
}
}
}
Notice that:
model.get('people[0..1].titles[0].name',
'people[0..1].titles[0].rating')
The entor points we pass in are quite simialr, actually we can group them:
model.get('people[0..1].titles[0]["name", "rating"]')
You will still get the same result.
