<title>Customizing The Ticket System</title>
<nowiki>
<h2>Introduction</h2>

This guide will explain how to add the "assigned_to" and "submitted_by" fields
to the ticket system in Fossil, as well as making the system more useful.  You
must have "admin" access to the repository to implement these instructions.

<h2>First modify the TICKET table</h2>

<blockquote>
Click on the "Admin" menu, then "Tickets", then "Table".  After the other fields
and before the final ")", insert:
<pre>
  ,
  assigned_to TEXT,
  opened_by TEXT
</pre>
And "Apply Changes".  You have just added two more fields to the ticket
database!  NOTE: I won't tell you to "Apply Changes" after each step from here
on out.  Now, how do you use these fields?
</blockquote>

<h2>Next add assignees</h2>

<blockquote>
Back to the "Tickets" admin page, and click "Common".  Add something like this:
<pre>
set assigned_choices {
  unassigned
  tom
  dick
  harriet
}
</pre>
Obviously, choose names corresponding to the logins on your system.  The
'unassigned' entry is important, as it prevents you from having a NULL in that
field (which causes problems later when editing).
</blockquote>

<h2>Now modify the 'new ticket' page</h2>

<blockquote>
Back to the "Tickets" admin page, and click "New Ticket Page".  This is a little
more tricky.  Edit the top part:
<pre>
  if {[info exists submit]} {
     set status Open
     set opened_by $login
	 set assigned_to "unassigned"
     submit_ticket
  }
</pre>
Note the "set opened_by" bit -- that will automatically set the "opened_by"
field to the login name of the bug reporter.  Now, skip to the part with "EMail"
and modify it like so:
<pre>
&lt;th1>enable_output [expr { "$login" eq "anonymous"}]&lt;/th1>
&lt;tr>
&lt;td align="right">EMail:
&lt;input type="text" name="private_contact" value="$&lt;private_contact>" size="30">
&lt;/td>
&lt;td>&lt;u>Not publicly visible&lt;/u>. Used by developers to contact you with
questions.&lt;/td>
&lt;/tr>
&lt;th1>enable_output 1&lt;/th1>
</pre>
This bit of code will get rid of the "email" field entry for logged-in users.
Since we know the user's information, we don't have to ask for it. NOTE: it
might be good to automatically scoop up the user's email and put it here.

You might also want to enable people to actually assign the ticket to a specific
person during creation. For this to work, you need to add the code
for "assigned_to" as shown below under the heading "Modify the 'edit ticket' page".
This will give you an additional combobox where you can choose a person during
ticket creation.
</blockquote>

<h2>Modify the 'view ticket' page</h2>

<blockquote>
Look for the text "Contact:" (about halfway through).  Then insert these lines
after the closing tr tag and before the "enable_output" line:
<pre>
<tr>
  &lt;td align="right">Assigned to:&lt;/td>&lt;td bgcolor="#d0d0d0">
  $&lt;assigned_to>
  &lt;/td>
  &lt;td align="right">Opened by:&lt;/td>&lt;td bgcolor="#d0d0d0">
  $&lt;opened_by>
  &lt;/td>
</pre>
This will add a row which displays these two fields, in the event the user has
<a href="./caps/ref.html#w">ticket "edit" capability</a>.
</blockquote>

<h2>Modify the 'edit ticket' page</h2>

<blockquote>
Before the "Severity:" line, add this:
<pre>
&lt;tr>&lt;td align="right">Assigned to:&lt;/td>&lt;td>
&lt;th1>combobox assigned_to $assigned_choices 1&lt;/th1>
&lt;/td>&lt;/tr>
</pre>
That will give you a drop-down list of assignees. The first argument to the TH1
command 'combobox' is the database field which the combobox is associated to.
The next argument is the list of choices you want to show in the combobox (and
that you specified in the second step above. The last argument should be 1 for a
true combobox (see the <a href="th1.md#combobox">TH1 documentation</a> for
details).

Now, similar to the previous
section, look for "Contact:" and add this:
<pre>
  &lt;tr>&lt;td align="right">Reported by:&lt;/td>&lt;td>
  &lt;input type="text" name="opened_by" size="40"
   value="$&lt;opened_by>">
  &lt;/td>&lt;/tr>
</pre>
</blockquote>

<h2>What next?</h2>

<blockquote>
Now you can add custom reports which select based on the person to whom the
ticket is assigned.  For example, an "Assigned to me" report could be:
<pre>
SELECT
  CASE WHEN status IN ('Open','Verified') THEN '#f2dcdc'
       WHEN status='Review' THEN '#e8e8e8'
       WHEN status='Fixed' THEN '#cfe8bd'
       WHEN status='Tested' THEN '#bde5d6'
       WHEN status='Deferred' THEN '#cacae5'
       ELSE '#c8c8c8' END AS 'bgcolor',
  substr(tkt_uuid,1,10) AS '#',
  datetime(tkt_mtime) AS 'mtime',
  type,
  status,
  subsystem,
  title
FROM ticket
WHERE assigned_to=user()
</pre>
