I want to know if I can display the count of child records in the parent table view.
Something similar to the count you can display in the child table tab.

How shall this look like?

If you mean something like this ...


... then ...

1. Create a new calculated field in your master-table, integer, readonly
2. On “Calculated field” tab, check "[X] Automatically calculate the value…"
3. Place the following code into the textarea:

   Code: Select all

   SELECT concat('<span class="badge">', count(*), '</span>' )
   FROM `TABLENAME_CHILDTABLE`
   WHERE `COLUMNNAME_LOOKUPFIELD`= '%ID%'
   

4. In line 2,replace TABLENAME_CHILDTABLE by the name of your child-table
5. In line 3 replace COLUMNNAME_LOOKUPFIELD by the column name of the lookup field in your child-table which is referencing your master table
6. Generate your application and (re-) load the table view of master table

Thank you Jsetzer. works fine.

Hi Jan,
Correct me if I am wrong, in your suggested steps...
the calculated field should not be integer if you are putting the "<span class="badge">.... right?
It should be VarChar or text field.

Thanks.

Hi, without having checked this, I think you are right, thanks a lot for pointing this out and thank you for all your contributions!

Reason: when answering the request, in first step I was only displaying count and so integer was perfect. In a follow up step I have added that UI badge using concat and did not change the data type. My fault. Anyway: it still works in UI for displaying the badge, which was the requirement. It will not store actual count in DB.

no worries Master Jan....
