Report with TracTicketsCustomFields

Here are some examples of how to generate simple custom reports from TracTicketsCustomFields.

Example 1

A report to show a Milestone summarize time inverted, new field test_one is Time to resolve a Ticket.

Enjoy!

Trac.ini:

[ticket-custom]
test_one = text
test_one.label = Inverted Time

Custom SQL:

SELECT 
   milestone as Project,
   sum(p.value) as Inverted_Time
   FROM ticket t, ticket_custom p
   WHERE p.ticket = t.id and p.name = 'test_one'
   group by milestone
   ORDER BY milestone

Example 2

Here's another longer example … I have four fields in my ticket-custom, and I want them all to be seen in the report. If the existing field was a NULL, the report code adds the word "None" to the output, so I'm getting rid of that with a CASE statement. The main magic is the series of LEFT OUTER JOINs, which let me access each custom field in turn.

Trac.ini:

[ticket-custom]
charge = text
charge.label = Charge

noncharge = text
noncharge.label = Non charge

sitevisit = text
sitevisit.label = Site visit

oohours = text
oohours.label = Hours

Custom SQL:

SELECT DISTINCT 

   id AS ticket,
   (CASE WHEN c.value ISNULL THEN '' ELSE c.value END) AS charge,
   (CASE WHEN n.value ISNULL THEN '' ELSE n.value END) AS nocharge,
   (CASE WHEN s.value ISNULL THEN '' ELSE s.value END) AS sitevisit,
   (CASE WHEN o.value ISNULL THEN '' ELSE o.value END) AS oohours,
   milestone AS customer,
   summary, component, status 

  FROM ticket t,enum p

  LEFT OUTER JOIN ticket_custom c ON
       (t.id=c.ticket AND c.name='charge')

  LEFT OUTER JOIN ticket_custom n ON
       (t.id=n.ticket AND n.name='noncharge')

  LEFT OUTER JOIN ticket_custom s ON
       (t.id=s.ticket AND s.name='sitevisit')

  LEFT OUTER JOIN ticket_custom o ON
       (t.id=o.ticket AND o.name='oohours')

  WHERE (p.name=t.priority AND p.type='priority' AND status='closed')
 
  ORDER BY milestone

Example 3

Going by the philosophy, you can never have too many examples, here's another one:

I added a custom ticket field to provide an idea of the percentage of the ticket completed so far. This is a simple dropdown list where the developer can log their progress to the nearest 20%.

trac.ini:

[ticket-custom]
progress = select
progress.label = Percent completed
progress.options = 0|20|40|60|80|100
progress.value = 0

Then to generate a simple report containing the new field, based on the default 'Active Tickets' report, I ended up with this:

Custom SQL:

SELECT p.value AS __color__,
   id AS ticket, summary, component, version, milestone, severity,
   (CASE status WHEN 'assigned' THEN owner||' *' ELSE owner END) AS owner,
   time AS created,
   changetime AS _changetime, description AS _description,
   reporter AS _reporter,
  (CASE WHEN c.value = '0' THEN 'None' ELSE c.value END) AS progress
  FROM ticket t LEFT OUTER JOIN ticket_custom c ON t.id = c.ticket AND c.name = 'progress'
     JOIN enum p ON p.name = t.priority AND p.type='priority'
  WHERE status IN ('new', 'assigned', 'reopened')
  ORDER BY p.value, milestone, severity, time

Notes

• the OUTER JOIN is the key to getting this to work
• I'm not totally fluent in SQL, so this may not be the simplest way, but it works for me

Example 4

I have added a few custom fields to track roughly the amount of work spent on each ticket. One field is the estimated work (in days) and the iother is the actual work (in days). I needed a simple report to summarize the total amount of work for each milestone: estimated and actual.

trac.ini:

[ticket-custom]
estimate = text
estimate.label = Estimate

actual = text
actual.label = Actual

Custom SQL:

SELECT 
   milestone AS Iteration,
   SUM(estimate.value) AS Estimate,
   SUM(actual.value) AS Actual

  FROM ticket t

  LEFT OUTER JOIN ticket_custom estimate ON
       (t.id=estimate.ticket AND estimate.name='estimate')

  LEFT OUTER JOIN ticket_custom actual ON
       (t.id=actual.ticket AND actual.name='actual')

  GROUP BY milestone 

Example 5

We wanted to query all custom_ticket.value of a certain type (custom_ticket.name), where a different custom_ticket.value of the same ticket was met.

trac.ini:

[ticket-custom]
duration = text
duration.label = Duration

customer = text
customer.label = Customer

This obviously didn't work:

Custom SQL:

SELECT 
  ticket_custom.value AS Duration

  FROM ticket_custom

  WHERE ticket_custom.name = 'duration'
  AND ticket_custom.value = 'Our Customer'

What we did was make a "loop" INNER JOIN ticket_custom on ticket_custom.ticket like this:

Custom SQL:

SELECT 
  tc1.value AS Duration

  FROM ticket_custom tc1

  INNER JOIN ticket_custom tc2
  ON tc1.ticket = tc2.ticket

  WHERE tc1.name = 'duration'
  AND tc2.value = 'Our Customer'
