Default value for Date field?

[dylanmccurry]

I have a Date field I've added to all pages in my site, called 'pageDate'.

<pageDate
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/coral/foundation/form/datepicker"
    displayedFormat="MMMM DD, YYYY"
    displayTimezoneMessage="{Boolean}true"
    fieldDescription="Page Date used for Sorting"
    fieldLabel="Page Date used for sorting purposes in search scenarios"
    name="./pageDate"
    renderReadOnly="{Boolean}false"
    required="{Boolean}true"
    type="date" 
        />

How can I make this field default to the current date upon page creation?

To add a default value to a field, you can use "defaultValue"

<pageDate
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/coral/foundation/form/datepicker"
    displayedFormat="MMMM DD, YYYY"
    displayTimezoneMessage="{Boolean}true"
    fieldDescription="Page Date used for Sorting"
    fieldLabel="Page Date used for sorting purposes in search scenarios"
    name="./pageDate"
    renderReadOnly="{Boolean}false"
    required="{Boolean}true"
    type="date" 
    defaultValue="{Date}{now}"
        />

This leads to a build error:

[ERROR] ValidationViolation: "jackrabbit-nodetypes: Property {}defaultValue does not have a valid value: not a valid date format: {now}"

[Anmol_Bhardwaj]

{Date} is the data type and then in place of {now}, you would need to set time dynamically from the back-end.

Something like this,

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));

child.setProperty(cpropertyName,calendar);

So this works if I put it into the getPageDate() property accessor, but the dialog itself is not updated with the current date after re-opening, it's still blank.  Is there a way to intercept some sort of OnSave where I can add logic like this?  e.g., I want the content author to visually see the value that we are defaulting to?

@dylanmccurry You can use the _cq_template/.content.xml node for this, with the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0"
          xmlns:jcr="http://www.jcp.org/jcr/1.0"
          xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
          jcr:primaryType="nt:unstructured"
          pageDate="{Date}2023-02-06T00:00:00.000+05:30">
</jcr:root>

Hope this helps!

Yes, but what about tomorrow?  How do I make the system automatically select the current date?

@dylanmccurry Probably for the dynamic value you might need to inject it via dialog clientlib js, if {now} is not working or via sling model.
