Add one row per value in an EnumList column list.
For this example, the table from which the row-addition process will be initiated is called Control Table. The table to which new rows will be added is called Target Table. Use your own names as you see fit. Note that they could even be the same table. Control Table must allow updates; Target Table must allow adds.
Control Table must have at least two columns for this process: EnumList (type EnumList; a list of Enum values; may be virtual); and Add Count (type Number; the number of the next row to add; may not be virtual). Column names may be changed as desired.
Add Count should be blank or zero initially.
This is the action that you should invoke to add the rows: it does everything.
if(
isblank([Add Count]),
isnotblank([EnumList]),
([Add Count] <= count([EnumList]))
)
This manages the Add Count column value, which contains the index of the next value in the EnumList for which a row is to be added. Itโll start at 1 and increment to the count of items in the EnumList.
([Add Count] + 1)
TRUE
(or blank)This action adds one row to the Target Table table for the Enum value of this rowโs EnumList at the position indicated by Add Count (but only if the value isnโt blank).
index([EnumList], [Add Count])
isnotblank(index([EnumList], [Add Count]))
This action implements a loop by recursively performing action (1) for each successive value in the EnumList.
list([_thisrow])
TRUE
(or blank)Return to action (1) and add actions (2), (3), and (4) to its Actions list.
Hi steve,
I have used your idea above thanks for that genius idea.
I have changed a few things to make it editble friendly, so with the changes it will update the target table rows based on the control table enumlist field on edit.
Note: I made it ref table so you have to have another coulmn in the target table called Parrent, and you can remove the coulmn "add count" in the control table.
This is the action that you should invoke to add the rows: it does everything.
[EnumList]<>[Related Target Table][Enum]
This will delete all records that you removed from the enumlist coulmn on an edit
select(Target Table[Key],and([Parent]=[_THISROW].[Key],not(in([Enum],[_THISROW].[Enumlist]))))
This action adds one row to the Target Table table for the Enum value of this rowโs EnumList (it will deduct all current records and add only new ones added to EnumList, so it will support edits)
This action implements a loop by recursively performing action (1) for each successive value in the EnumList.
Return to action (1) and add actions (2), (3), and (4) to its Actions list.
Hi Steve,
This Add one row per value in an EnumList column list is a lifesaver for me. I've set everything up and works ok for me.
My Control table is also the target table.
The only thing I see in the data of the table , is that the initial row where the actions are triggerd from by saving the form, stays in the data table after creating all the new rows from the selections in the enumlist. see example
I'm trying to figure out how to delete this first row , because this leaves an empty value on the [enum] which to me is no more needed.
I'm kinda stuck here on how to resolve this.
I was thinking of removing the row with id and made 2 columns, to figure out how it works.
Column "Copy of id on adding row" = id of first row is added to the new row in action 3 also added adcount to see how it counts.
Column "Copy of id of first row" = id is copied to this column in action 2
I would like to thank you in advance for your time.
Kind regards Didier
Update I added an action 5 --> delete row in action 1
This action is executed after the complete enumlist has been copied to a row.
The first row is not deleted but cleared, so i need to figure out how to remove the empty row from the google sheet.
An other approach could be, that i'm trying to figure out, is to copy the last value in the enumlist to the first row with all the enumlist values. So I don't have to delete anything and worry about an empty row in my database.
This is because my control table is also my target table.
Resolved my issue when "controltable is also the targettable"--> got 2 solution
1st is to delete (clear) the row with a fifth action delete row. which then you need a script to effectively remove the empty row in your database
2nd see below
In action 1
Added -1 to count(Enumlist) and removed = (because i need to have 1 value for the first row.
if(
isblank([Add Count]),
isnotblank([Selectedcodes]),
([Add Count] < count([Selectedcodes])-1)
)
In action 2
Add count = (add count +1) because i need the first item in the enumlist to be in the first row, so start adding row with the second value in the enumlist
In Action 3 add the second item in the enumlist
Enum = index([enumlist], [Add Count]+1)
In action 5
Add the first item in the enumlist in the first row
Data set the values of some collimns in this row
Enum=index([Enumlist], 1)
behavior is true
@Steve I have done as per the instructions. But it is telling me "Service Name is invalid". In my app service name is the enumlist, with a base type of ref.
@Aditya Try changing base type to text
