Re: [Roundup-users] Understanding a line in issue.item.html

Hi r2d2:

I answered on IRC, but I can condense/fix and copy it here. From IRC:

>11:04.55 (EDT) - r2d2: i want to extend this with a second keyword field named project
>11:05.57 (EDT) - r2d2: is there a way to use something like an format-string within the filter='...' expression?

You can use printf formatting:

      filter='status=waiting,in progress,needs attention;keyword=%s' %
context.keyword.plain()

it's just python at that point. I assume you are trying to find all
"waiting,in progress" status  ... issues that match the
current context. Searching with mutlilinks is a bit tricky. What you
have I think will be an or search by default.

So if there were two keywords you would get any project that has either keyword.

You have to create a boolean expression if you have a multilink. If
you have two keywords you would filter using keyword1,keyword2,-3
which is an RPN/postfix expression and'ing (-3) the two keywords. See
the definition of filter in
roundup/hyperdb.py.

If you are going to be doing complex filtering, add a utility function
and do the work in the utility function. Trying to do any extensive
logic/python programming within the template is unreadable/subject to
quoting issues (as you kind of lose the " or need to escape it since
its used to delimit the tal expression.

See https://roundup-tracker.org/docs/customizing.html#adding-a-time-log-to-your-issues-4
for an example of registering a utility method.
