get_foo_display isn't functioning well with DRF
I have this class MEMBERSHIP_STATUS: PENDING = 0 DECLINED = 1 MEMBER = 2 and the model is class Membership(models.Model): MEMBERSHIP_STATUS = ( (MEMBERSHIP_STATUS.PENDING, _('Pending')), (MEMBERSHIP_STATUS.DECLINED, _('Declined')), (MEMBERSHIP_STATUS.MEMBER, _('Member')), ) user = models.OneToOneField(User, on_delete=models.CASCADE) status = models.IntegerField(max_length=10, choices=MEMBERSHIP_STATUS, default=MEMBERSHIP_STATUS.PENDING) def __str__(self): return self.user.username now, in serializers.py, I have this class MembershipSerializer(serializers.ModelSerializer): user = UserSerializer() family = FamilySerializer() status = serializers.SerializerMethodField() class Meta: model = Membership fields = '__all__' def get_status(self, membership): return membership.get_status_display() This always returns 0, Even tho I'm expecting it to return the display. The solution I found is class MEMBERSHIP_STATUS: PENDING = '0' DECLINED = '1' MEMBER = '2' Changing the Integers to Strings seems to work, But I don't understand why. Any explaination? -

Django - Fetch values from children via Foreign Key, while looping the parent objects in template
I am quite new to Django and probably this will be totaly noobish question, but I am stuck in this situation and bit help would be much appreciated. I have the following models: class BillType(models.Model): name = models.CharField(max_length=200) created_on = models.DateTimeField(default=datetime.now, blank=True) def __str__(self): return self.name class Bill(models.Model): bill_type = models.ForeignKey(BillType, on_delete=models.CASCADE) month = models.CharField(max_length=200) amount = models.IntegerField() due_date = models.CharField(max_length=200) note = models.TextField(blank=True) recurring = models.BooleanField(default=True) currency = models.CharField(max_length=100) created_on = models.DateTimeField(default=datetime.now, blank=True) def __str__(self): return self.month and the following view: def billingOverview(request): bill_types = BillType.objects.all() context = { 'bill_types': bill_types, } return render(request, 'management/billing-overview.html', context) In the template, I am using the For loop to loop through the BillType objects and that part is working fine. However, for each of the looped BillType objects that are rendered separately in the template, I need to access and show the data for 'month' corresponding to that particular BillType object. Can you help me with an example of how I can do that action? Thanks, Bojan In case the template is needed: {% for bill_type in bill_types %} <!-- Billing overview column --> <div> <!-- Billing overview widget --> <div class="bo-widget"> <div class="bo-widget-header"> <div> <h2>{{ bill_type.name }}</h2> <span>Overview of {{ bill_type.name|lower … -
TypeError: Tried to update field dashboard.Product.province with a model instance
I am trying to save the url in my object where the encrypted id of my object is located. So it writes all fields and finally tries to add the url to the already called object. Then my error is shown 'TypeError: Tried to update field dashboard.Product.province with a model instance.' How do I save my url after calling object.save () once.

Django: Update Fields, throws "Save with update_fields did not affect any rows." Even though row is updated
I have a table with a row that needs to be updated. This Table however has a trigger. For simplicity I have limited the trigger to present my case. Alter TRIGGER Cow_UpdateTrigger ON Cow FOR update AS select * from Cow This trigger gets called when an Update occurs, however the trigger doesn't modify any fields with in the Cow Table. The code below shows me attempting to updating the name of a Cow. It throws the following exception upon saving. "Save with update_fields did not affect any rows." However the name of the cow actually has been updated. cow = Models.Cow.objects.get(pk=1) cow.name = "Life" cow.save(update_fields=["name"]) # Raises Error, However successfully updates fields. Further Analysis with the cursor. c = cursor.execute("""Update COW set cow_name = "Love" where COW_ID = '1' """) c.rowcount The following code is ran with three different update trigger scenarios. The returning row count reflecting the rows changed differs. Trigger is removed and Update is performed. Row count = 1 The Trigger is created with a select statement . Row count = -1 however a row has changed A trigger is created with an update statement to randomly change an attribute in updated row. This also returns … -

Django-Ckeditor seems to turn dropped PDFs into .. an image?
When people drop PDF files into posts on my forum, django-ckeditor somehow magically turns it into an image of page-one! (The PDF is gone.)

Django - Custom admin page not displaying properties

I supply these properties in the CustomUserCreationForm and the CustomUserChangeForm, however I can't still view these properties. Does anybody know how I can view these fields when I view or create a new user object? Thank you. -

Problem witch pyplot graphics from a same view in django
I use a view to create a graph with matplotlib. This view is like this and depend on the id_projet argument. def Graphique_view(request,id_projet): """ s'occupe de l'affichage du graphique d'un projet """ projet = Projet.objects.get(pk=id_projet) date_debut = projet.date_debut semaine_fin = delta_semaine(date_debut,projet.date_fin) f= plt.figure(figsize=(16,9)) plt.title('graphique') x1=[] y1=[] semaine = 0 ETP = 0 while semaine <= semaine_fin : compteur = 0 for bilan in Bilan_horaire.objects.filter(projet=projet): if delta_semaine(date_debut,bilan.date) == semaine : ETP += bilan.ETP compteur +=1 bilan_semaine=bilan if compteur != 0 : x1.append(bilan_semaine.date) y1.append(ETP) semaine+=1 plt.plot(x1,y1,label = 'ETP travaillés') ETP = 0 for livrable in projet.livrables : semaine = delta_semaine(date_debut,livrable.dernier_jalon.date_jalon) for utilisateur in projet.utilisateurs: ETP += ETP_ressources_livrable.objects.filter(utilisateur=utilisateur).filter(livrable=livrable).order_by('date_modification').reverse()[0].ETP_estime x=[date_debut,livrable.dernier_jalon.date_jalon,livrable.dernier_jalon.date_jalon] y=[ETP,ETP,0] plt.plot(x,y,label=livrable.libelle) myFmt = mdates.DateFormatter('S%W - %Y') axes = plt.gca() axes.xaxis.set_major_locator(mdates.DayLocator(interval=7)) axes.xaxis.set_major_formatter(myFmt) plt.xticks(rotation = '-50') plt.xlabel('temps (semaines)') plt.ylabel('heures (ETP)') plt.legend() canvas = FigureCanvasAgg(f) response = HttpResponse(content_type='image/jpg') canvas.print_jpg(response) matplotlib.pyplot.close(f) return response The url associate is projet/<int:id_projet>/graphique This is the result for projet/9/graphique for instance And this is the result for projet/10/graphique for instance Now if try to display this 2 images in a html like this : <img src="{% url 'graphique_projet' 9 %}" /> <img src="{% url 'graphique_projet' 10 %}" /> I have that which is not what I want. Any help would be appreciate. …
