Django Query Get Last Record with a Group By
I am trying to get all the last records based on the id, sorted my the month. this gives me the last record, qs = Cashflow.objects.filter ( acct_id = a.id ).order_by('-month')[:1] And this groups the accounts, qs = Cashflow.objects .filter ( acct_id = a.id ) .values ( 'acct_id' ) .annotate ( count = Count ( 'acct_id' ) ) .values ( 'acct_id', 'count' ) .order_by ( ) How how can I combine the two queries into one? Group by acct_id, sort by "month" and get last record. is this even possible? thanks -
Python: How to resolve python setup.py egg_info failed with error code 1
I'm stuck with a project in Django where I have to install MySQL-python. When I'm running pip install MySQL-Python I got this error: Command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-Ue6URf/MySQL-Python/ I used brew as suggested in some answers here but didn't help at all. I'm using a Mac machine with the last Python3 and the last Django version. I have MampPro last version which I'm using the MySQL service.

NoReverseMatch at /groups/ Reverse for 'single' with keyword arguments '{'slug': 'first-group'}' not found
I'm so lost, my code matches exactly to this tutorial I'm following (I've triple checked) and yet I can't seem to find the issue. I am trying to have all my social network's group display on a page and that page should be the groups_list.html page.

Django Querysets -& select_related: unable to retrieve a set of foreignkey objects
I'm sure I'm doing something very stupid here as this isn't a complex issue and in other frameworks it's not a problem. class ArticlePage(Page): ... city = models.ForeignKey(City, on_delete=models.PROTECT, null=True) ... Then in a view: qs = ArticlePage.objects.filter(city__isnull=False).filter(city__name__icontains=self.q).select_related('city') So I've tried many permutations of the above query, and none of them return the desired result. All the results are a set of ArticlePage type instead of City. All I'm trying to do is return a set of results of type City that contains every City object that is referenced by an ArticlePage, but I'm going insane trying to make this happen with django querysets, and I'm sure I'm just doing something very silly. Appreciate any advise here. -

ModelForm saving over model data with empty fields
I'm building an Edit form for a model in my database using a ModelForm in Django. Each field in the form is optional as the user may want to only edit one field. The problem I am having is that when I call save() in the view, any empty fields are being saved over the instance's original values (e.g. if I only enter a new first_name, the last_name and ecf_code fields will save an empty string in the corresponding instance.) The form: class EditPlayerForm(forms.ModelForm): class Meta: model = Player fields = ['first_name', 'last_name', 'ecf_code'] def __init__(self, *args, **kwargs): super(EditPlayerForm, self).__init__(*args, **kwargs) self.fields['first_name'].required = False self.fields['last_name'].required = False self.fields['ecf_code'].required = False The view: def view(request, player_pk = ''): edit_player_form = forms.EditPlayerForm(auto_id="edit_%s") if "edit_player_form" in request.POST: if not player_pk: messages.error(request, "No player pk given.") else: try: selected_player = Player.objects.get(pk = player_pk) except Player.DoesNotExist: messages.error(request, "The selected player could not be found in the database.") return redirect("players:management") else: edit_player_form = forms.EditPlayerForm( request.POST, instance = selected_player ) if edit_player_form.is_valid(): player = edit_player_form.save() messages.success(request, "The changes were made successfully.") return redirect("players:management") else: form_errors.convert_form_errors_to_messages(edit_player_form, request) return render( request, "players/playerManagement.html", { "edit_player_form": edit_player_form, "players": Player.objects.all(), } ) I've tried overriding the save() method of the form to ... -
Django ModelForm to update profile picture does not save the photo
I want to enable my users to change their profile picture. When uploading a photo, I am redirected to the success page but the photo is not uploaded to the folder and the associated field is blank. Note that if a user already had a photo, it resets the field to blank so after submitting the form, the user has no photo anymore. My guess is that the form.save(commit=False) does not upload the photo nor update the field as it should but I do not understand why ! Here is the model, view and form : The Profil model: class Profil(models.Model): user=models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) photo_profil=models.ImageField(null=True,blank=True,upload_to='img/profils', verbose_name="Photo de profil", help_text="La taille du fichier doit être inférieure à {0}Mo.

Custom Middleware get_response not working

Django - multiple url routers, same url?
So i am trying to have a server control page in a django applications with a list of servers that links via uuid to starting, cloning and stopping each respective server. (think a really terrible openstack UI). This is the code that generates the url. <li><a href="{% url 'start' uuid=uuid %}">Start</a></li> <li><a href="{% url 'clone' uuid=uuid %}">Clone</a></li> <li><a href="{% url 'stop' uuid=uuid %}">Stop</a></li> Unfortunately it would appear that when I click the clone link on the web application it starts rather than clones the server, meaning it is running the start function in view. Here is how the urls are defined: urlpatterns = [ url(r'^$', views.index, name='index'), #url(r'^$', views.transfer, name='transfer'), url(r'^malware/$', views.malware, name='malware'), # Add this /malware/ route url(r'^about/$', views.about, name='about'), # Add this /about/ route url(r'^(?P<uuid>[\w\-]+)$', views.start, name='start'), url(r'^(?P<uuid>[\w\-]+)$', views.paranoidfish, name='paranoidfish'), url(r'^(?P<uuid>[\w\-]+)$', views.clone, name='clone'), url(r'^(?P<uuid>[\w\-]+)$', views.stop, name='stop'), url(r'^(?P<uuid>[\w\-]+)$', views.transfer, name='transfer'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) I'm sure there's something basic i'm missing here, as always any help would be appreciated. -
