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 |
||||

# 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). |
||||
|
||||
|
||||
# Usage |
||||
|
||||
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: |
||||
|
||||
<template name="myTemplate"> |
||||
... |
||||
{{sortable items=Players handle=".sortable-handle" ghostClass="sortable-ghost" options=playerOptions}} |
||||
</template> |
||||
|
||||
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 |
||||
); |
||||
} |
||||
}; |
||||
} |
||||
}); |
||||
``` |
||||
|
||||

# RubaXa:Sortable Meteor demo |
||||
|
||||
This demo showcases the two-way integration between the reorderable list |
||||
widget [Sortable](https://github.com/RubaXa/Sortable/) and Meteor.js. Meteor |
||||
Mongo collections are updated when items are added, removed or reordered, and |
||||
the order is persisted. |
||||
|
||||
It also shows list grouping and control over what lists can give or receive |
||||
elements. You can only drag elements from the list to the left onto the list |
||||
to the right. |
||||
|
||||
## Usage |
||||
|
||||
The example uses the local package from the checkout, so it needs to wire |
||||
up some files (`package.js` and `package.json`). This is done by the handy |
||||
run script: |
||||
|
||||
### Windows |
||||
|
||||
git clone git@github.com:RubaXa/Sortable.git |
||||
cd Sortable |
||||
git checkout dev |
||||
cd meteor\example |
||||
run.bat |
||||
|
||||
### Elsewhere |
||||
|
||||
git clone git@github.com:RubaXa/Sortable.git |
||||
cd Sortable |
||||
git checkout dev |
||||
meteor/example./run.sh |
||||
|
||||
## Prior art |
||||
|
||||
### Differential |
||||
|
||||
Differential wrote [a blog post on reorderable lists with |
||||
Meteor](differential.com/blog/sortable-lists-in-meteor-using-jquery-ui) and |
||||
[jQuery UI Sortable](http://jqueryui.com/sortable/). It served as inspiration |
||||
for integrating [rubaxa:sortable](rubaxa.github.io/Sortable/), |
||||
which uses the HTML5 native drag&drop API (not without [its |
||||
limitations](https://github.com/RubaXa/Sortable/issues/106)). |
||||
The reordering method used by the Differential example can lead to data loss |
||||
though, because it calculates the new order of a dropped element as the |
||||
arithmetic mean of the elements before and after it. This [runs into limitations |
||||
of floating point precision](http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible) |
||||
in JavaScript after <50 reorderings. |
||||
|
||||
### Todos animated |
||||
|
||||
http://todos-dnd-animated.meteor.com/ ([source](https://github.com/nleush/meteor-todos-sortable-animation)) |
||||
is based on old Meteor Blaze (back then Spark) API, and won't work with current versions. |
||||
It does showcase some neat features, such as animation when collection elements |
||||
are reordered by another client. It uses jQuery UI Sortable as well, which lacks |
||||
some features vs. rubaxa:Sortable, e.g. text selection within the item. |
||||

* element to the average of the orders of the elements around it - |

* http://programmers.stackexchange.com/questions/266451/maintain-ordered-collection-by-updating-as-few-order-fields-as-possible

* The downside is that the order field in the DB will increase by one byte every |

* time an element is reordered. |
||||
* 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. |
