#9839 closed defect (wontfix)

Pipe is not appended to single option

Reported by: Jan Beilicke Owned by: CM Lubinski
Priority: normal Component: MultiSelectCustomFieldsPatch
Severity: normal Keywords:
Cc: Trac Release: 0.12


I just noticed that some queries didn't return all matching tickets. At first I thought it might be caused by old data, that was not updated (see also #9731). It turned out, that every update to a ticket (ticket properties or comments) removes the pipe of single options again.

When the multi had more than one selected options (which worked fine) and all but one options are removed, the remaining option is stored without a pipe.

I assume that the pipe is simply not set in the __setitem__() where isinstance(value, list) is processed - maybe the value isn't a list anymore?

Feedback is highly appreciated. :)

Summary: Pipe is not appended for single optionsPipe is not appended to single option

After some investigation I came up with the following patch. It contains the original MultiSelectPatch (only plus a quick fix for my issue, applied in populate():

    132132    def __setitem__(self, name, value):
    133133        """Log ticket modifications so the table ticket_change can be updated

     135        if isinstance(value, list): #   account for multi-selects
     136            value = '|'.join(value) + '|'
    135137        if name in self.values and self.values[name] == value:
    136138            return

    146148                value = value.strip()

    166168            self[name] = values.get(name, '')

    171173            if name[9:] not in values:
    172174                self[name[9:]] = '0'
     176        for f in self.fields:
     177            # We do something similar for empty multi-selects
     178            if f['type'] == 'multi' and not f['name'] in values:
     179                self[f['name']] = ''
     180            # Single multi values should be lists, too.
     181            elif f['type'] == 'multi' and f['name'] in values:
     182                if not isinstance(values[f['name']], list):
     183                    self[f['name']] = [values[f['name']]]
    174186    def insert(self, when=None, db=None):
    175187        """Add ticket to database.

So far it seems to work, the pipe gets (and stays) appended to single values.

TracMultiSelectBoxPlugin is pretty good. I'm going to mark this plugin as deprecated in favor of that one, or MultiSelectFieldPlugin, which I haven't looked at.
