Body
You mentioned a separate process: if your problem is to capture the traceback in process A and show it in process B, as if the exception was actually raised in the latter, then I'm afraid there is no clean way to do it. I would suggest to serialize the traceback in process A, send it to process B and from there raise a new exception that includes the former in its description. The result is a somewhat longer output, but it carries information about both processes stacks. In the following example there aren't really two separate processes, but I hope it makes my point clearer: <pre><code>import traceback, StringI def functionInProcessA(): raise Exception('Something happened in A') class RemoteException(Exception): def __init__(self, tb): Exception.__init__(self, "Remote traceback:\n\n%s" % tb) def controlProcessB(): try: functionInProcessA() except: fd = StringIO.StringIO() traceback.print_exc(file=fd) tb = fd.getvalue() raise RemoteException(tb) if __name__ == '__main__': controlProcessB() </code></pre> Output: <pre><code>Traceback (most recent call last): File "a.py", line 20, in <module> controlProcessB() File "a.py", line 17, in controlProcessB raise RemoteException(tb) __main__.RemoteException: Remote traceback: Traceback (most recent call last): File "a.py", line 12, in controlProcessB functionInProcessA() File "a.py", line 4, in functionInProcessA raise Exception('Something happened in A') Exception: Something happened in A </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
