Hide a field if it is not updated during last day

[etantonio]

Hy,
in my application I've the following report:

the latest column shows the latest datetime ok the corresponding TRK. Maybe for some reason like in the figure, the latest timestamp is really old so I don't want to show that row, for example I want to see only the rows updated during last day.

Maybe a way to achieve this is:

<ma-now update-interval="1 minutes" output="theTimeNow"></ma-now>
..
      <ng-if="!TRK_0_1_automa_state.time.isBefore(theTimeNow | maMoment:'subtract':24:'hours'")>
        <h5>{{TRK_0_1_automa_state.time | date:'yyyy-MM-dd  HH:mm:ss'}}</h5>
      </ng-if>
..
      <ng-if="!TRK_1_1_automa_state.time.isBefore(theTimeNow | maMoment:'subtract':24:'hours'")>
        <h5>{{TRK_1_1_automa_state.time | date:'yyyy-MM-dd  HH:mm:ss'}}</h5>
      </ng-if>

but the code seems to be always true, so it is not ok because both automa_state.time are showed.

Any idea about where is the problem?
Thanks,
Antonio

Hi @etantonio

The problem is that TRK_0_1_automa_state.time is not a moment.js object and you cannot use .isBefore() on it. It is an epoch timestamp (i.e. a number, specifically of seconds since 1980).

I would suggest using this

<ma-now update-interval="1 minutes" output="theTimeNow" on-change="theTimeADayAgo = $value.clone().subtract(24, 'hours')"></ma-now>

Then

<div ng-if="theTimeADayAgo.isBefore(TRK_0_1_automa_state.time)">

Thanks Jared,
in any case, using the following code:

    <ma-now update-interval="1 minutes" output="theTimeNow" on-change="theTimeADayAgo = $value.clone().subtract(24, 'hours')"></ma-now>
    <md-grid-tile class="dark-gray">
        <h5>{{theTimeADayAgo|moment:'format':'D MMM YYYY - HH:mm'}}</h5>
    </md-grid-tile>
 	  <md-grid-tile class="dark-gray">
      <h5>{{theTimeNow|moment:'format':'D MMM YYYY - HH:mm'}}</h5>
    </md-grid-tile>

I've this result:

and in fact the row filtering based on datetime seems to be not working.

moment is not a valid filter name, it is maMoment as per your first post. You could also just call the function directly instead of using the filter -

theTimeADayAgo.format('D MMM YYYY - HH:mm')

at the end of all the simplest working solution for me seems to be

<ma-now update-interval="1 minutes" output="theTimeNow"></ma-now>
<ma-calc input="theTimeNow | moment:'subtract':24:'hours'" output="theTimeADayAgo"></ma-calc>

and then:

<md-grid-list
      md-cols="11"
      md-gutter="0px"
      md-row-height="35px" ng-if="theTimeADayAgo.isBefore(TRK_0_1_automa_state.time)">
