Re: Bug with regroup ? (which does not regroup as he shoud / I hope...)

[Nicolas Steinmetz]

For the record, I modified a little bit my object but the key was in 
precising a lot |dictsort like the following case :

{# -- Compétences techniques -- #}
{% if user_techskill %}
Comptences techniques :
{% for tskill in user_techskill %}
{% regroup tskill.name.all|dictsort:"domain.id" by domain as 
grouped %}

 {% for group in grouped %}
 {{ group.grouper }} :
{% for item in group.list %}
{{ item.name }},
{% endfor %}

 {% endfor %}

{% endfor %}
{% endif %}

Regards,
Nicolas

So should I fill a ticket or do I make something wrong ?

My view is quite simple :

# Display the detail for a given CV
def cv_detail(request, firstname, lastname):
 user = User.objects.get(first_name=firstname, last_name=lastname)
 user_civilstate = user.civilstate_set.all()
 user_summary = user.summary_set.all()
 user_formation = user.formation_set.all()
 user_language = user.language_set.all()
 user_hobby = user.hobby_set.all()
 user_contact = user.contact_set.all()
 user_skill = user.skill_set.all().order_by('domain',)
 user_firm = user.entreprise_set.all().order_by('-start_date',)
 user_experience = user.experience_set.all().order_by('-start_date',)
 user_document = user.document_set.all()
 return render_to_response('cv/cv_detail.html', {'user_civilstate': 
user_civilstate, 'user_summary': user_summary, 'user_formation': 
user_formation, 'user_language': user_language, 'user_hobby': 
user_hobby, 'user_contact': user_contact, 'user_skill': user_skill, 
'user_firm': user_firm, 'user_experience': user_experience, 
'user_document': user_document})
# cv_detail = cache_page(cv_detail, 60 * 60 * 12)

I tried this but the bug persists. Sometimes it works well (technical 
skills are well regrouped by technical domaines) but if I refresh, it's 
no longer the case.

I even tried this on an easier object and it does not work more 
efficiently (user_skill in my view). If I do not add .order_by() in the 
view, and add the |dictsort:"" filter, I have the same bug. If I add the 
order_by() and the dictsort filter, bug remains. It only works well if I 
add the order_by() and remove the dictsort filter.

However for the 1st object on which I had the bug, I cannot sort it in 
my views unless I decompose my model...

Any other clue ?

Re: Bug with regroup ? (which does not regroup as he shoud / I hope...)

[Florian Apolloner]

I am not quite sure wheter my answer is correct, as you didn't post
your view, but I think this is your problem (copy from
http://www.djangoproject.com/documentation/templates/#regroup):
Note that {% regroup %} does not work when the list to be grouped is
not sorted by the key you are grouping by! This means that if your
list of people was not sorted by gender, you'd need to make sure it is
sorted before using it, i.e.:
{% regroup people|dictsort:"gender" by gender as grouped %}

Hope this helps,
Florian Apolloner
