Need help developing blueprint script for creating monthly roster on calendar

Configuration Blueprints
1

Hello, I am new to home assistant & I am having trouble with writing a blueprint script that can take multiple dates (about 16) then automatically create the same calendar event for each of the different dates that were inputted.

I want the events to be created in my HA work calendar as I already built an automation that relies on the event being found in the calendar for that day.

I have started with the blueprint script however I am unsure how to continue with the actions.

The current blueprint does not work, & I wasn’t sure if I should continue calling service calendar.create_event 16 times (1 for each input date)

Please let me know if there is a better way to do this or how I could continue/resolve my current blueprint.

Thank you!

blueprint:

#creating 16 date inputs for various shifts throughtout the month

I can’t help but think there is an easier way to do this in the front end somehow…

The suggested way to write blueprints is to create your in this case script code first as a script, then add the other stuff that makes it a blueprint. Then you first fight the script syntax, once you have that right you fight the changes for the blueprint syntax.
Creating an automation blueprint - Home Assistant.

Try that.

Now I see you have script syntax problems to start with, such as action: doesn’t go there and to complete what you are trying to do you need a loop or a bunch of choose statements or something. I don’t see any of that.

The basic structure of the script as @Sir_Goodenough mentioned would be something like:

alias: Create Roster
description: ""
variables:
  wd1: !input datetime_1
  wd2: !input datetime_2
    ....
  workdates: >-
    {{[wd1, wd2] | select('defined')|reject('in', [none, '']) | list}}
sequence:
  - repeat:
      sequence:
        - service: calendar.create_event
          target:
            entity_id: calendar.work
          data:
            summary: Work
            start_date_time: "{{ repeat.item }} 07:00:00"
            end_date_time: "{{ repeat.item }} 19:00:00"
      for_each: "{{ workdates }}"
mode: single

Thank you both for your assistance & quick replies!

I have updated the blueprint based on your inputs, however now I am getting an input not defined error, any ideas or references on what steps I need to do in order to define them.

Error Message: Invalid blueprint: Missing input definition for datetime_15, datetime_2, datetime_8, datetime_3, datetime_14, datetime_13, datetime_10, datetime_5, datetime_7, datetime_16, datetime_12, datetime_11, datetime_4, datetime_1, datetime_9, datetime_6

Make sure to indent input: to the same depth as the other blueprint keys and add a default for each “datetime” inputs so you can leave some blank if necessary (either "" or null should work as the default value).

Get rid of the work_dates: in the variables block… or modify the template to look within the dictionary.

FWIW, since you’re setting this up as a Blueprint it would make more sense to also add inputs for summary, calendar, start time and end time as well instead of static values… otherwise, you should just use a regular script.

Blueprint with additional inputs and simplified variables block

EDIT: There was an errant ' in the workdates template that has been corrected both here and above.
