Error assigns a ticket to a Developer

[ivanelsonnunes@…]

Always this error occurs. When will I assign a ticket.

I noticed that this only occurs in the ticket's created [1] email2trac. The plugin is being broken TracjsGantt.

Maybe this is a chain reaction. I use customized and required fields. However, the tickets created by email2trac not carry these custom and required fields. This explains?

I am a bit swamped at this moment, but email2trac can handle custom fields. It was added in ticket #101. I have no experience with the TracjsGantt? plugin. So maybe i do not use the right entry point for custom fields ticket or TracjsGantt? does not register its self properly. I have to install the TracjsGantt? to test it.

I think I know the reason of the problem, although I do not know the solution. The email2trac're not adding in ticket_custom table. Tickets created directly in trac, are always created in ticket_custom table.

ok in the emsil2trac code we check for custom fields:

## default trac value
1116	            #
1117	            if not field.get('custom'):
1118	                value = self.get_config('ticket', 'default_%s' %(name) )
1119	
1120	                ## skip this field can only be set by email2trac.conf
1121	                #
1122	                if name in ['resolution']:
1123	                    value = None
1124	
1125	            else:
1126	                ##  Else get the default value for reporter
1127	                #
1128	                value = field.get('value')
1129	                options = field.get('options')
1130	
1131	                if value and options and (value not in options):
1132	                     value = options[int(value)]

If you run in debug mode are the custom fields then shown? You can test with the supplied email test message.

So it sees the custom fields,but it has no default values. Are they defined?

[ivanelsonnunes@…]

Are not defined. Trac is standard treatment when the fields are not defined. Where Trac itself defines default values​​.

[ivanelsonnunes@…]

In method def set_ticket_fields(self, ticket):

If you change this:

 if value:
    user_dict[name] = value
    

To this:

 if value:
    user_dict[name] = value
 else:
     user_dict[name] = ''

[bas]

Is this the solution for your problem?

[ivanelsonnunes@…]

Replying to bas:

Is this the solution for your problem?

In theory yes! Showed no more problem. However I declared all the fields /etc/email2trac.conf. The default fields I left null.

• In /etc/email2trac.conf:

  DEFAULT_keywords  : ServiceDesk
  DEFAULT_component : TRAC
  DEFAULT_priority  : Alta
  DEFAULT_severity  : Normal
  DEFAULT_type      : Triagem
  DEFAULT_aplicacao :
  DEFAULT_blockedby :
  DEFAULT_blocking  :
  DEFAULT_due_assign:
  DEFAULT_due_close :
  DEFAULT_parents   :
  DEFAULT_projeto   :
  DEFAULT_setor     :
  DEFAULT_solicitante:

If the above patch is applied then the declaration of the custom fields in email2trac.conf is not necessary anymore?

If the above patch is applied

I have not tested it:

then the declaration of the custom fields in email2trac.conf is not necessary anymore?

[ivanelsonnunes@…]

I tested. With this patch. No need to declare all fields in email2trac.conf file.

Thank you.
