Plone 6 default "pat-datetime-picker" problems

[jensens]

pat-datetimepicker

1. is not documented anywhere pat-datetime-picker is undocumented Patternslib/Patterns#1038
2. is not backwards compatible with pat-pickadate which means if one used the pattern until 5.2 (or 6.0a4 to b) the editor experience is not the same. Ie. like time is displayed even if pattern setting on widget in Python with `"time": False".
3. pat-date-picker seems to be the successor?

I don't shed a tear for pat-pickdate. But the new situation is not satisfactory at all.

Furthermore:

• no timezone selection implemented (in code it says "todo").
• default settings on input do not relate with those I can find in code in https://github.com/Patternslib/Patterns/blob/master/src/pat/datetime-picker/datetime-picker.js

I consider this a blocker for any release-candidate of Plone (in fact earlier detected this would have been a blocker for beta too).

Another one: If in settings -> date time the first day of the week is monday, the datepicker ignores it and still shows sunday.

That said: If I use a DateField with DateFieldWidget uses pat-date-picker (first day of week ignored too).

My previous assumption that date-picker is the successor of datetime-picker is not correct.
Here are some facts:

• pat-date-picker is the patternslib implementation of Pikaday (https://www.npmjs.com/package/pikaday) with some options to enable a date picker for <input type="date" /> fields. in plone.app.z3cform this is automatically wired for schema.Date Fields. Unfortunately the import in mockup is missing, so no effect.

• pat-datetime-picker is used per default for schema.Datetime Fields and (used to) generate 2 fields

  • date field which reuses pat-date-picker logic
  • time field with basic (native) time input

But now with this commit Patternslib/Patterns@b14503d datetime-picker checks for browser native date picker support and skips the logic completely, regardless of the pattern_option you set (https://github.com/Patternslib/Patterns/blob/master/src/pat/datetime-picker/datetime-picker.js#L26).

I guess this need some additional brain cycles to fix. What is our default use case? What are additional use cases?

[petschki]

Maybe @thet can give some insights, what the future plans for pat-datetime-picker are. For now I'm good with native behavior only.

[jensens]

Well, I need the "today" button for both. And it would be cool if it would start with monday.

Why do we need this imported in Mockup btw?

The date-picker language is wrong too:
