#19884 closed Bug

Inspectdb on Oracle doesn't produce correct field types — at Version 12

Reported by: Anssi Kääriäinen Owned by: nobody
Component: Database layer (models, ORM) Version: 1.9
Severity: Normal Keywords:
Cc: felisiak.mariusz@… Triage Stage: Accepted
Has patch: no Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: no UI/UX: no

Description (last modified by Mariusz Felisiak)

The test inspectdb.test_field_types() has multiple errors, at least:

  • CharField lengths not correctly inspected (returns double the length of generated field)
  • FloatField not correctly inspected (returns DecimalField with max_digits=-127)
  • DateTimeField is inspected as TimeField

Getting all these to work correctly will be somewhat hard. So, the suggested short-term fix is to just mark the test as expectedFailure on Oracle. Inspectdb isn't high-priority as the output should be hand-edited in any case.

comment:3 by Shai Berger, 11 years ago

I just posted ​PR 2225 which breaks inspectdb.test_field_types() in two: a test_number_field_types() which passes (the PR includes a fix to the FloatField issue), and test_field_types() which does all the rest and is still marked expectedFailure; most of the fields tested there are CharFields under Oracle, so fixing makes little sense indeed.

I would have committed this immediately, except that the breaking of the test method includes some not-entirely-trivial factoring-out of code, and I'd like a second eye on that.

Made Oracle introspect FloatFields correctly

Broke InspectDBTestCase.test_field_types in two:

  • a test_number_field_types, which now passes on Oracle too
  • a test_field_types, for all non-numeric fields, which is still expected to fail

Also made some pep8 fixes in the tests file. Refs #19884

Thanks Tim Graham for review.

Because this problem is still present in 1.9 I updated the version number
