Hi Belen and Alex,
It took a lot of trial and error, but I now have a solution for 5962 :
dreyna/regex_filter_5962
Alex, I wanted to call out the nasty technical issues I encountered, plus the
solution that I finally put into place. The reason for this is that I
discovered that two methods that should have worked both failed, and I had to
go to a more heuristic solution in the end to satisfy the requirements (which I
am not totally happy about).
1) Original failure.
It turns out that:
IF you select a filter that uses regex with alternation (e.g.
'vhistory__file_name__regex:conf/(local|bblayers).conf') ...
AND you add a search string ...
AND there are more than one 'search_allowed_fields' value ...
THEN (and only then) you will get a Django database fatal error.
This is nasty. The "views.py" will build the queryset, but it is damaged and
the first lookup returns a "Exception Value: user-defined function raised
exception" (I am guessing it is against the lamda's that filter the Q objects
for 'search_allowed_fields' fields).
2) I then tried to use the facility to specify multiple filter compares that "
_get_filtering_query" would appear to support.
'vhistory__file_name__icontains;vhistory__file_name__contains:conf/local.conf;conf/bblayers.conf'
I however could not get both clauses to work. I even used 'contains' and then
'icontains' to get around the dictionary overwrite.
Is this the expected usage? Is this feature supposed to work (I see no other
examples in "views.py)?
3) My final solution was to do a simple file path test against
"<project_path>/conf/", with the observation that only the local configuration
files meet this criteria. This seems a hack, but it works and I have no
alternate proposal at this time.
4) By the way, I observed that the database schema does not seem to provide the
path to the project's directory. In #3 I cheated and munged the
"cooker_log_path" value.
I suggest that providing the formal path in the database is very important to
general users and especially build farm managers (who will also want access to
the machine name and/or IP address), so that they can correlate a build report
with its definitive location from their remote location.
I think that I will file a defect to track this concern.
Thanks,
David
