Subject Re: Requesting rpc ticket.query advice
Date Mon, 16 Mar 2015 17:43:43 GMT
Hi Olemis

No problem, appreciate the advice.

I think I finally realize why I was having trouble with the query 
language. I think I missed a painfully simple part of the syntax, namely 
the use of the "or" operator. I referenced the "Query Language" section 
at the bottom of http://trac.edgewall.org/wiki/TracQuery.

For example:

query:?owner=~analytics & loc=Millis & time=Feb+15%2C+2015..Mar+18%2C+2015
&
or
&
owner=~analytics & loc=Easton & time=Feb+11%2C+2015..Mar+18%2C+2015

etc

So that was a "duh" moment for me. I would much prefer to use the built 
in bloodhound query language instead of the SQL.

Two additional questions, please.

(1) Can I add a custom field that can be queried like creation and 
modification time? According to 
http://trac.edgewall.org/wiki/TracTicketsCustomFields seems like the 
answer is no.

I ask because I am generating tickets for conditions that have a 
beginning and end which do not always match the creation or modification 
time of the ticket. I store those as epoch time in a pair of custom fields.

I would like to display tickets constrained by the condition begin and 
or end. I do have the hack-ish option of using a "starts with" on an 
epoch time to narrow the results and then further sort the results in 
the code that fetched the query results.

Am I missing a simple alternative?

(2) Is there a way to access manually entered comments from a 
bloodhound  (not sql) query?

I ask because I need to allow retrieval and modification of ticket 
comments from a different UI talking RPC with BH. I could certainly add 
a free form text field, but it seems like the built in comment mechanism 
might make more sense.


The parameterized report was a good reminder, if I still need to go to 
the report execute option that will be very helpful.

thanks again
Mark
