How to bind <umb-editor> date picker values inside an ng-repeat?

Hi there,

I'm creating a custom property editor that can store multiple prices for an item based on a date range.

The JSON for the value looks like this:

{
  "prices": [
  {
     "dateFrom": "2018-01-01T00:00:00Z",
     "dateTo": "2018-01-31T00:00:00Z",
     "price": 100
  },
  {
     "dateFrom": "2018-02-01T00:00:00Z",
     "dateTo": "2018-04-30T00:00:00Z",
     "price": 120
  },
  {
     "dateFrom": "2018-05-01T00:00:00Z",
     "dateTo": "2018-07-31T00:00:00Z",
     "price": 150
  }
  ]
}

Here's my dateprices.editor.html file:

<div ng-controller="MT.DatePricesController">

    <table class="date-prices">
    <thead>
        <tr>
            <th scope="col">From</th>
            <th scope="col">To</th>
            <th scope="col">Price</th>
        </tr>
    </thead>
    <tbody>
        <tr ng-repeat="priceItem in model.value.prices">
            <td>{{ priceItem.dateFrom }}</td>
            <td>{{ priceItem.dateTo }}</td>
            <td><input ng-model="priceItem.price" type="number" class="clr-number"/></td>
        </tr>
    </tbody>
    </table>

</div>

I'd really like to use the Umbraco date picker for the dateFrom and dateTo fields, but I can't work out how to bind it up from inside an ng-repeater block like this.

For simple situations, it looks like it can be connected up like this:

<umb-editor model="datePickerSingle"></umb-editor>

With the "datePickerSingle" model defined in the controller:

$scope.datePickerSingle = {
        view: "datepicker",
        config: {
            pickDate: true,
            pickTime: false,
            pick12HourFormat: false,
            format: "D MMM YYYY"
        },
        value: $scope.model.value.myDate
    };

But for my example, I want to bind multiple date pickers to the values inside my ng-repeat block.

Anyone got any tips or examples of this being done?

Thanks,

Mike

Hi Mike,

I think you can better use umbDateTimePicker if you wanne use a umbraco styled date picker. and make your change event generic so he can update your model.

Thanks Marcel.

I'm looking at the umbDateTimePicker, but I'm still not sure how to manage the situation where the picker is inside an ng-repeat loop.

Each iteration of the ng-repeat loop has two dates, and I'm trying to work out how to bind these "From" and "To" dates for each row to date pickers:

Date picker inside an ng-repeat loop

Is this possible? I can only find examples that bind a single date value to a date picker; nothing with multiple values inside an ng-repeat loop.

Thanks,

Mike

Hi Mike,

Only a week or so delayed response to your tweet ... hopefully I can try to help. Although I suspect something details may get lost in translation, e.g. prepare yourself, as I doubt this will be a copy-n-paste solution.

OK, you can use the <umb-date-time-picker options="..." /> directive, like so...

<tbody>
    <tr ng-repeat="priceItem in prices">
        <td>
            <umb-date-time-picker options="priceItem.dateFrom" />
        </td>
        <td>
            <umb-date-time-picker options="priceItem.dateTo" />
        </td>
        <td>
            <input ng-model="priceItem.price" type="number" class="clr-number" />
        </td>
    </tr>
</tbody>

... but it requires a bit of extra fiddly config in the values ... e.g.

{
    dateFrom: {
        defaultDate: new Date("2018-04-30T12:34:56Z"),
        pickDate: true,
        pickTime: false,
        useSeconds: false,
        format: "D MMM YYYY",
        icons: {
            time: "icon-time",
            date: "icon-calendar",
            up: "icon-chevron-up",
            down: "icon-chevron-down"
        }
    },
    dateTo: /* snipped for brevity */,
    price: 100
}

The date picker is using the Bootstrap DateTimePicker library; the full config options for it can be seen here: https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web.UI.Client/lib/datetimepicker/bootstrap-datetimepicker.js#L1412-L1435
Make note, that the defaultDate is the one that is used. I'd have expected it to be called value, but I dunno.

To be honest, you wont want to keep duplicating the datetimepicker config, so you could whack that in a variable and extend it, like so...

var defaultDateTimeConfig = {
    pickDate: true,
    pickTime: false,
    useSeconds: false,
    format: "D MMM YYYY",
    icons: {
        time: "icon-time",
        date: "icon-calendar",
        up: "icon-chevron-up",
        down: "icon-chevron-down"
    }
};

...

dateFrom: angular.extend({ defaultDate: new Date("2018-04-30T12:34:56Z") }, defaultDateTimeConfig)

but that's just a suggestion

The reason I've used new Date("") instead of a string, is that in Bootstap DateTimePicker, it checks if the value is a Date object, if it's a string, then it will attempt to parse it using the date-format provided, see here:

https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web.UI.Client/lib/datetimepicker/bootstrap-datetimepicker.js#L1297

Meaning that if your date/string value is "2018-04-30T12:34:56Z" and your format is "D MMM YYYY", then it just ain't gonna work. Better to work with actual Date objects.

Now, when I said this wouldn't be a copy-n-paste solution, the issue is how to persist all these values back to $scope.model.value? ... and that's the bit that take a LOT of trial & error. aka, I don't have a solid answer for that, sorry.

There are various things you can do with angularjs watchers or the formSubmitting event ... they are all a bit hacky. Feel free to take a look at how I tackled this for my Property List editor...

https://github.com/umco/umbraco-property-list/blob/develop/src/Our.Umbraco.PropertyList/Web/UI/App_Plugins/PropertyList/js/propertylist.js#L119-L133

I hope some of this helps?

Cheers,
- Lee

@Mike,

I am currently on holiday but will try to make a sample to use it!

Hi Mike,

I've looked at the current implementation of the umb datetimepicker and unfortunately i don't see a way of passing the value. I think building your own directive is your best bett.
