Could canjs team please take care of typescript a bit
canlist.extend({
foo:() => {
// `this` is the window
},
bar() {
// `this` is the List instance
}
})
thanks! using function() {...} works
and then in the
.stache file use {{#with}} and access/edit the object properties?
"possibleEvents": {
"value": [],
"get": function () {
return Event.getList({}).then( function ( eventList ) {
return eventList;
});
}
},
"value": [],
"get": function () {
return Event.getList({}).then( function ( eventList ) {
return eventList;
});
}
},
I personally like to follow this pattern of having one property be the promise: https://github.com/donejs/bitballs/blob/master/public/components/player/list/list.js#L64-L68
Then use the promise’s value in a template, or wherever else: https://github.com/donejs/bitballs/blob/master/public/components/player/list/list.stache#L19
Also,
new Map() is not what you want, but just new Person(), right?
Here’s how I think I would approach what you’re doing: http://jsbin.com/taguluzeku/1/edit?html,js,output
Even if it were in a
get, it would only run again if something observable changed, but there’s nothing observable in that function.
Let’s say you did need to make that API call again because the arguments changed. That might look something like:
orderBy: {
value: "name"
},
playersPromise: {
get: function(){
return Player.getList({orderBy: this.orderBy});
}
}
@chasenlehara it does work in http://jsbin.com/taguluzeku/1/edit?html,js,console,output but when including it into my donejs project it will create the instance and even with default values, but if you modify any of the properties then it will “reset” the object (the
if condition is met):
type: function(newPerson) {
if (newPerson && newPerson instanceof Person === false) {
console.log('>>> debug data 1:', newPerson);
return new Person(newPerson);
}
return newPerson;
}
the problem after doing some debug is that the
newPerson is the value of the input field, so it will never have any valid data again (as it is just one plain value)
I thought
newPerson would at least be an object but only the currently selected input value is passed as newPerson
could it be can 2.x that is causing this?
the approach used by @chasenlehara works
but when I use it within the donejs project it won't
the way I use it looks like the jsbin (the last one) so you can set each of the properties
whenever you modify any of the inputs that are binded to a property of this new object then every input field is set with the
return new Person(newPerson) code
and
newPerson contains whatever you wrote on one of the inputs
not the complete object
every time you modify (even before saving) it will do that so as a result you enter data on any field and then all the fields are set to null/empty

How do you handle a bulk save or destroy?
I have something like this: let todos = TodoModel.getList() and every todo has a checkbox and are stored in a selection DefineList.
Now I want to delete the selected todo items.
selection.forEach(todo => {
todo.destroy();
});This results in multiple requests to the backend, how can I group these request?
Do I make a custom funtion in my model bulkDestroy and then splice them out of my todos list? Or how do you handle this?
