<p>Not quite clear on what you're saying about try/except/continue in for loops. The following is loosely based on the code you provide.</p> <pre><code>def failing_func(raster): raise ValueError("raster <%s> function has failed" % (raster)) def working_func(raster): print("raster <%s> function has succeeded" % (raster)) return True raster_list = [0, 1, 2, 3, 4, 5] for raster in raster_list: print("Processing <%s>" % (raster)) try: v1 = working_func("raster_1") v2 = failing_func("raster_2") v3 = working_func("raster_3") v4 = failing_func("raster_4") v5 = working_func("raster_5") except ValueError, e: print("Exception was raised: %s when processing item %s" % (str(e), raster)) continue </code></pre> <p>Which outputs:</p> <pre><code>Processing <0> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 0 Processing <1> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 1 Processing <2> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 2 Processing <3> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 3 Processing <4> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 4 Processing <5> raster <raster_1> function has succeeded Exception was raised: raster <raster_2> function has failed when processing item 5 </code></pre>

Guidance

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.
