error while adding csv-files with duplicate column names

[solvistas-hartmi]

Currently, it is not possible to add csv-files with duplicate column names, since these are also used as table-columns in postgres. In web the datapusher returns an "internal server error 500" at /api/3/action/datastore_create.

We discussed this at the meeting, and the general consensus was that although it might be possible to append a number to duplicate columns, it would introduce problems later in the process.

The best solution currently is to make sure there is a usable error message so that the user can correct the mistake and re-upload the file. This isn't to say it'll never handle it, but in the foreseeable future this is the safest approach (unless a PR appears from somewhere).

same issue with CKAN 2.4.1 . It would be great to get at least an error message pointing the real cause. now I get only:

Current Ckan (2.8) throws the right Error: Response: {"help": "http://h2893531.stratoserver.net/api/3/action/help_show?name=datastore_create", "success": false, "error": {"field": ["Duplicate column names are not supported"], "__type": "Validation Error...

Just encountered it. This may be safe to close - consensus on keeping it and correct error message are sufficient requirements in general to close issues - just my 2ct.
