#13543 closed defect (cantfix)

OperationalError: ambiguous column name: id

Reported by: Mikko Owned by:
Priority: normal Component: XmlRpcPlugin
Severity: normal Keywords:
Cc: Trac Release: 1.2

Description (last modified by Ryan J Ollos)

How to Reproduce

  1. Configure multiple custom fields ("dev", "sales", "users" in this case with possible values "", "S", "M", "L" and "XL" for each field).
  2. Open /query and build a custom query where you try to select multiple values for at least two custom fields and press "Update"
  3. Select the URL in the browser address bar, copy and paste it into another browser window.

Expected result:

The page should look the same as after (2) when "Update" has been pressed.

Actual result:

Error page without the query interface nor query results:

While doing a GET operation on /query, Trac issued an internal error.

The problem seems to be caused by incorrect caching when query with multiple custom fields is done via GET. If I build the same query using custom query UI and press "Update" button, the query runs fine. The query also seems to work once if the same query has not been run in a while.

The cause is probably similar to t:#13068 but this is about Filters because the problem still appears even with only Summary column selected.

Note: trac report bug button automatically selected XmlRpcPlugin as the component for this ticket, but I think it's not the correct one. I believe the problem is in core Trac ticket query implementation. I have left the Component field in this bug as-is because I'm not sure how this should be handled here.

This query had custom Filter on fields "dev", "sales" and "users".

Request parameters:

{u'col': [u'id',
 u'dev': [u'S', u'M'],
 u'order': u'priority',
 u'sales': [u'XL', u'L'],
 u'users': [u'XL', u'L']}

That is not an XmlRpcPlugin issue. → trac:#13068

comment:2 Changed 5 years ago by Jun Omae

Try one of the following:

  • Downgrade to Trac 1.2.2
  • Upgrade to Trac 1.2-stable
  • Apply the changes of trac:r16819

Thanks, manually applying changes from ​trac:r16819 fixed the issue.

I guess this will be fixed officially in 1.2.4.
