Re: Getting the right data to the template
Thank you for your input, Malcolm. I've made up something based on
your suggestions in revision 56:
http://codebrowse.launchpad.net/~mikl/kaplan/kaplan.dev/revision/56
Sorry for missing your last name in the commit message, but I was off-
line when I committed this (7 hour train journey, what would I do
without decentralised VCS.)
Kind regards,
Mikkel Høgh

It's not completely clear to me what you want to do here. Is this what
you are trying to accomplish: given a Task object, find all the
associated Term objects and group them by their vocabulary attribute?
If that's the case, then I think your current code is fairly close.
However, instead of storing term.title in the dictionary, just store the
term object itself and don't both joining the items together at the end.
This way, after calling refresh(), you can do something like this in
your template:
{% for elt in task.t.items %}
Vocabulary word is {{ elt.0 }}
Associated terms are:
{% for term in elt.1 %}
{{ term.title }}
{% endfor %}
{% endfor %}
(or anything more advanced). If you're using post-0.96 Django, you can
even write
{% for vocab, term in task.t.items %}
but that's mostly a matter of taste. The functionality is the same.
If you want to do this without the refresh() method, I suspect you're
probably out of luck. the hard part is the grouping based on the
vocabulary term -- you can't do that simply as a queryset. If it was me,
though, I wouldn't make refresh() adjust the task object. I would have
it return the dictionary, so you can do all of the above stuff as
{% for vocab, term in task.get_vocab_and_terms %}
without having to remember to call task.refresh() in your view.

Malcolm

Re: Getting the right data to the template
Hmm, the codebrowse link does not seem to work, sadly. You should be able to browse the repository here: http://codebrowse.launchpad.net/~mikl/kaplan/kaplan.dev/files The models are located in kaplan/todo/models.py and kaplan/taxonomy/ models.py Kind regards, Mikkel Høgh --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Getting the right data to the template
I have a bit of a problem - I'm creating a GTD-focused task management app for Django, mainly for my own benefit, but it's open source if any one cares. I've been trying to implement a taxonomy system like the one Drupal uses. Only problem is that I find it difficult to get the right data out into the template system. As an example, I have a list of Task objects, which is supposed to be displayed to the user. These Task objects all have Term object associated with them (ManyToMany). The Term objects belong (ForeignKey) to a Vocabulary object. I want to get the Term objects by their Vocabulary so I can display them in different columns. Lets say I have a Task object called 'Fix the apache configuration on xyz server', which has the Term objects 'Urgent' (from the Priority Vocabulary) and 'Work' (from the Context Vocabulary). Currently, I have a bit of a kludge where I've put a refresh method on the Task object that generates a dictionary with vocabulary names as keys and as value a string containing a comma-separated list of all the terms from that Vocabulary associated with the Term object in question. I would like to be able to access the Term objects directly in the template, so I could get the absolute URL for them in the "right" way or if that's not feasible, some other solution, because I need the aforementioned string to have links to the Term objects in question... You can see the model code in question here: http://codebrowse.launchpad.net/~mikl/kaplan/kaplan.dev/annotate/mikkel%40hoegh.org-20071015103825-kmr72968yz91serq?start_revid=mikkel%40hoegh.org-20071017164032-iz6zlgj3m735a5qe&file_id=svn-v2%3A1%4005d49af5-ae19-0410-aa10-c28341cc0fd9--src%2fdanet%2ftodo%2fmodels.py Checkout instructions etc. here: https://code.launchpad.net/~mikl/kaplan/kaplan.dev Any input will be greatly appreciated.
