- Line 56: Update _expand_rows_by_field and _expand_rows_by_count to enforce a
configured maximum cumulative expanded-row count before any list multiplication
or allocation, rejecting the report when the limit would be exceeded. Preserve
valid expansion behavior at or below the boundary, and add boundary tests
covering both helpers.
- Line 124: Update the repeat-count precedence check around
_expand_rows_by_count() to test report.repeatcount is not None, so persisted
zero is treated as configured and takes precedence over the JRXML repeat field.
Add a test covering repeatcount=0 alongside a JRXML repeat value.
- Around line 159-164: Validate request.POST.get('reportId') against the
submitted report/JRXML query association before calling _expand_rows_for_repeat;
if the ID is missing or does not belong to that report, do not apply its stored
repeat settings. Preserve repeat expansion only for a valid associated report
ID.

- Confirmed the report/label RepeatField functionality works in Specify7!
Record 000009240, shown below, should print 5 labels; 1 for skull, 2 for heart, 2 for muscle:

- Printing labels with RepeatCount works in Sp6 and Sp7 (note: I found that repeatCount will only work in Sp7 if the report/label was created in Sp6)
- Confirmed no error if repeatField contains unresolvable values, i.e. latitude1. label is simply printed once in those cases.
- Labels without repeatCount or repeatField work as expected.
- Labels with null value in repeatField field work as expected.

Testing instructions
- Open a label/report that has
RepeatFieldconfigured to usecountAmt. - Run the label against records where
countAmthas different values. - Verify labels are generated according to the
countAmtvalue.-
countAmt = 3produces 3 labels -
countAmt = 2produces 2 labels
-
- Verify null, zero, or invalid values default to a single label.
- Verify labels using
RepeatCountstill repeat the configured number of times. - Verify labels without repetition settings continue to behave as before.
Setting RepeatField to countAmt did not edit the label results. However, when I set it to 1,63-preparations.preparation.countAmt (from the label definition itself), the proposed changes worked correctly. Documentation should be written to cover this, because it might not be an intuitive solution for most users to try on their own.
Additionally, an error occurs (see Issue #8698) when editing the spReport form. This may be due to the version not updating, but you can see the edits are captured in the audit log.

Fixes #3434
Description
Restores Specify 6 style label repetition behaviour when printing labels.
This change adds support for:
Spreport.RepeatFieldrepeating rows based on a field value (for examplecountAmt)Spreport.RepeatCountrepeating rows a fixed number of timesspecify.repeat.count.fieldpropertyThe backend now expands report rows before sending data to the report renderer, and the report ID is passed from the UI to the report runner so stored report repetition settings can be applied.
Automated tests have been added for repeat-field expansion, repeat-count expansion, precedence rules, JRXML fallback behaviour, and end-to-end report execution.
This change restores Specify 6 label repetition behaviour using
RepeatField,RepeatCount, and thespecify.repeat.count.fieldJRXML property.No database schema changes or migrations are included in this PR.
