Packaging [Sortable](http://rubaxa.github.io/Sortable/) for [Meteor.js](http://meteor.com).
Reactive reorderable lists with [Sortable](http://rubaxa.github.io/Sortable/),
backed by [Meteor.js](http://meteor.com) collections:
* new elements arriving in the collection will update the list as you expect
* elements removed from the collection will be removed from the list
* drag and drop between lists updates collections accordingly
Demo: http://rubaxa-sortable.meteor.com
# Meteor
If you're new to Meteor, here's what the excitement is all about -
[watch the first two minutes](https://www.youtube.com/watch?v=fsi0aJ9yr2o); you'll be hooked by 1:28.
That screencast is from 2012. In the meantime, Meteor has become a mature JavaScript-everywhere web
development framework. Read more at [Why Meteor](http://www.meteorpedia.com/read/Why_Meteor).
# Issues
# Usage
If you encounter an issue while using this package, please CC @dandv when you file it in this repo.
Simplest invocation - order will be lost when the page is refreshed:
```handlebars
{{sortable <collection|cursor|array>}}
```
Persist the sort order in the 'order' field of each document in the collection:
```handlebars
{{sortable items=<collection|cursor|array> sortField="order"}}
```
Along with `items`, `sortField` is the only Meteor-specific option. If it's missing, the package will
assume there is a field called "order" in the collection, holding unique `Number`s such that every
`order` differs from that before and after it by at least 1. Basically, keep to 0, 1, 2, ... .
Try not to depend on a particular format for this field; it *is* though guaranteed that a `sort` will
produce lexicographical order, and that the order will be maintained after an arbitrary number of
reorderings, unlike with [naive solutions](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible).
## Passing options to the Sortable library
{{sortable items=<collection|cursor|array> option1=value1 option2=value2...}}
{{sortable items=<collection|cursor|array> options=myOptions}}
For available options, please refer to [the main README](../README.md#options). You can pass them directly
or under the `options` object. Direct options (`key=value`) override those in `options`. It is best
to pass presentation-related options directly, and functionality-related settings in an `options`
object, as this will enable designers to work without needing to inspect the JavaScript code:
# DONE
<template name="myTemplate">
...
{{sortable items=Players handle=".sortable-handle" ghostClass="sortable-ghost" options=playerOptions}}
</template>
* Instantiation test
Define the options in a helper for the template that calls Sortable:
```js
Template.myTemplate.helpers({
playerOptions: function () {
return {
group: {
name: "league",
pull: true,
put: false
},
sort: false
};
}
});
```
## Events
All the original Sortable events are supported. In addition, they will receive
the data context in `event.data`. You can access `event.data.order` this way:
```handlebars
{{sortable items=players options=playersOptions}}
```js
Template.myTemplate.helpers({
playersOptions: function () {
return {
onSort: function(/**Event*/event) {
console.log('Moved player #%d from %d to %d',
event.data.order, event.oldIndex, event.newIndex
);
}
};
}
});
```

* 2) Adjust the orders of the intervening items. This keeps the orders sane (integers)
* but is slower because we have to modify multiple documents.
* TODO: we may be able to update fewer records by only altering the
* order of the records between the newIndex/oldIndex and the start/end of the list.
* 3) Use regular precision arithmetic, but when the difference between the orders of the
* moved item and the one before/after it falls below a certain threshold, adjust
* the order of that other item, and cascade doing so up or down the list.
* This will keep the `order` field constant in size, and will only occasionally
* require updating the `order` of other records.
*
* For now, we use approach #2.
*
* @param {String} itemId - the _id of the item that was moved
* @param {Number} orderPrevItem - the order of the item before it, or null
* @param {Number} orderNextItem - the order of the item after it, or null
