The use of ForeingKey on django when I create an object is also creating an object from the foreignkey model
I have a function on the main app of the website i'm working on that creates a User - the model name is "Usuario" (different from the default User model that django provides). The model is: class Usuario(models.Model): email = models.CharField(max_length=250) data_cadastro = models.DateTimeField(default=now) telefone = models.CharField(validators=[phone_regex], max_length=17, blank=True) # validators deve ser uma lista renda = models.DecimalField(default=0,max_digits=14,decimal_places=2) longitude = models.DecimalField(default=0,max_digits=20,decimal_places=12) latitude = models.DecimalField(default=0,max_digits=20,decimal_places=12) (the names of the fields are in Portuguese) This model is connected to a different one in another app by a simple foreing key (usuario). The other model is: from core.models import Usuario class Simulacao(Usuario): usuario = models.ForeignKey(Usuario, related_name="Usuario_contas", on_delete=models.CASCADE) data_simulacao = models.DateTimeField(default=now, verbose_name="Data simulação") tem_conta = models.BooleanField(default=False) class Meta: verbose_name = 'Simulação' verbose_name_plural = 'Simulações' def __str__(self): return self.nome def __unicode__(self): return self.nome The function where I create the "Simulacao" object is this one: from .models import Simulacao, Tipo_Pessoa from core.models import Usuario from django.utils.timezone import now def cadastro_simulacao(form, email): nova_simulacao = Simulacao.objects.create(usuario = Usuario.objects.get(email = email), tem_conta=form['tem_conta']) usuario.Usuario_contas_set.add(nova_simulacao) usuario.save() All i've done is based on the Django documentation: https://docs.djangoproject.com/pt-br/2.1/topics/db/examples/many_to_one/ I have also tried the function like that: from .models import Simulacao, Tipo_Pessoa from core.models import Usuario from django.utils.timezone import now def cadastro_simulacao(form, email): nova_simulacao ... -
Django - override __str__ method for a single queryset
I have my User model, and overrode the __str__ method as such: def get_django_user_full_name(self): return self.get_full_name() User.add_to_class("__str__", get_django_user_full_name) Now the issue: I have a specific dropdown menu where I want it to display the users in a different manner, namely: def get_user_name_last_first_email(self): return self.last_name + ', ' + self.first_name + ', ' + self.email User.add_to_class("last_first_email", get_user_name_last_first_email) The specific dropdown menu form field is: assignee = forms.ModelMultipleChoiceField(queryset=User.objects.filter(groups__name='actor').order_by('last_name'), required=False) However, this dropdown menu, as it should, displays in the default "first_name last_name" way. I cannot figure out a way to force it to instead display the names as "last_name, first_name, email' in the dropdown menu - using the custom property I built or not. The only way I found to override it is to use values_list() but that either only returns one field (if flat=True) or returns all 3, but as an ugly tuple. tl;dr How do I customize the display (i.e. the __str__ method) of a single queryset? -
django.db.utils.ProgrammingError: relation "django_content_type" does not exist

Django join tables with ORM and conditional Where clause
I have 3 tables to join; Personnels,Machines and Locations. I want to join these tables and add where clause to end of the ORM query if request body includes filtering data. Here is my raw query (I want to write this query in django ORM) and sample if condition for where clause; query = '''select * from "Sales" as "SL" INNER JOIN "Personnels" as "PL" ON ("SL"."PersonnelId" = "PL"."user_id") INNER JOIN "Machines" as "MC" ON ("SL"."MachineId" = "MC"."id") INNER JOIN "Locations" as "LC" ON ("SL"."LocationId" = "LC"."id") ''' if request.method=='POST': if request.data['personnel_name'] and request.data['personnel_name'] is not None: personnel_name = request.data['personnel_name'] condition = '''WHERE "PL"."name" = '{0}' '''.format(personnel_name) query = query+condition As it is seen, there are lots of quotes (if I don't write,postgresql makes some trouble) and code is not clean. My question is, how can I write this query with using django ORM? As you see, I want to add where conditions dynamically. How can I achieve that? -

Assign a separate html page to each user in django admin
I have 15 users in my django model and they are displayed on an html page by using the html code: {% for user in users %} <h3>{{ user.get_full_name }}</h3> {% endfor %} I want for each user to have a different html page. I would like for the name of the user to be a hyperlink and when you click on the link, it will go to the html page of that user's page. views.py: def user1(request): if request.method =='POST': if form.is_valid(): form.save() return redirect('user1') else: return render(request, 'accounts/user1.html') def user2(request): if request.method =='POST': if form.is_valid(): form.save() return redirect('user2') else: return render(request, 'accounts/user2.html') How do I connect each user in the "for users" with their own html page. Since I am not writing out every user manually and adding a tag, I am confused on how to give each user a separate html page using this format. -
Is there a limitation on running db query in imported function in django tests?
I am using function in views to query db (postgresql), calculate values and return list of lists. When I call it from views.py I get what is expected. When I call it from test.py I get empty list (not error, not None). To investigate I have created list of lists in views function manually and it was returned just fine (so there is no issue with import or length of returned value). It seems that if I call function imported from views that makes a db query and it is called from TestCase object then the db query is not done. Why? from django.test import TestCase from <my app>.views import calc import datetime from pytz import timezone class CalcTestCase(TestCase): maxDiff = None def test_calc_image(self): start_time = datetime.datetime(2018, 9, 1, 0, 0, 0, 0, tzinfo=timezone('UTC') ) finish_time = datetime.datetime(2018, 10, 1, 0, 0, 0, 0, tzinfo=timezone('UTC') ) instance_type = "test" output = calc(instance_type, start_time, finish_time) test_output = [[test, values, in],[list, of, lists]] self.assertEqual(output, test_output) -

Add form choices as options in a select tag html
I'm in my final project and I'm a little bit lost on what I'm doing now. I'm developping a website and I need to insert some choices into a html select tag, I mean, that choices must be options of this select tag.

Organizing templates in a django project
I am trying to use the "app-specific" approach to organizing various django apps. For example: - app2 - __init__.py - urls.py - views.py -templates/ - app2 - __init__.py - urls.py - views.py -templates/ - manage.py - settings.py One issue I'm having with this though is where to put the base templates that everything inherits from? For example, at the top of all my templates I have {% includes "base.html" %}, but if I'm doing the above I don't see how I could do this in a logical fashion. -
def() defined in a class are not executed
I defined a class that has a get method. When the user sends a request with the get method, the method fetches the data from the database, and then makes some changes and sends it to the user. However, I tried it. When the user initiates a get request, only the following two lines of code are executed queryset = Product.objects.all() serializer_class = ProductSerializer and the get method is not executed. ## urls.py router.register(r'getList', ProductListViewset) ## views.py class ProductListViewset(viewsets.ModelViewSet): queryset = Product.objects.all() serializer_class = ProductSerializer def get(self, request, format=None): serializer = ProductSerializer data = serializer.data username = data.get('user_name') user = User.objects.get(username__exact=username) new_data = { 'id': data.get('id'), 'user_name': data.get('user_name'), 'user_image_URL': user.get('user_image_URL'), 'c_time': data.get('c_time'), 'goods_price': data.get('goods_price'), 'title': data.get('title'), 'description': data.get('description') } return Response(new_data, 200) -

render Django HTML tag using JavaScript
I have installed in my project django-contib-comments and I have an HTML that displays the list of comments and also displays the form to enter a new one. I now want to use Ajax to submit the form without a page refresh and on success to add the submitted comment to the list. I have done most of the work, but I'm sure there must be an easier way to achieve this. my question is if there is a way for me to render a Django HTML tag within a javascript something like this: document.getElementById("comments").innerHTML = {% render_comment_list for obj %} so far this is the code I have done: 1) I don't want to change anything in the django-contrib-comments project (i am avoiding to override methods. 2) I used the standard tags in django-contrib-comments to render a list of comments. {% render_comment_list for obj %} 3) Created a JavaScript that handles the submit of the form and then creates a new entry in the list. function submit_comments(event) { event.stopPropagation(); $.ajax({ type: $('#comment_form').attr('method'), url: $('#comment_form').attr('action'), data: $('#comment_form').serialize(), cache: false, dataType: "html", success: function (html, textStatus) { var comment_count_btn = document.getElementById('comment-text-vertical-btn'); if (comment_count_btn != null) { if (!isNaN(parseInt(comment_count_btn.innerHTML))) { comment_count_btn.innerHTML = ... -

Django username/password and api key JWT authentications
I have some requirements where I need to be able to authenticate the user either with username/password or with an api_key and return a JWT token for both cases. My approach with the username/password: if request.data['email'] and request.data['password']: try: user = User.objects.get(email=request.data['email']) except User.DoesNotExist: return Response({'Error': "Invalid username."}, status=status.HTTP_400_BAD_REQUEST) if user: if user.check_password(request.data['password']): payload = jwt_payload_handler(user) token = jwt_encode_handler(payload) exp = datetime.now() + api_settings.JWT_EXPIRATION_DELTA return Response({'token': token, 'exp': format(exp, 'U')}, status=status.HTTP_200_OK) else: return Response({'Error': "Invalid password."}, status=status.HTTP_400_BAD_REQUEST) where jwt_payload_handler is implemented as: def jwt_payload_handler(user): payload = { "id": user.id, "date": get_user_join_date(user), "username": user.username, } return payload One of my questions is doesn't the keyword username need to be in the payload for the token to be a valid one? What would a good approach be in the case of the api_key considering the key is not related to a user? Should i create a default user that will be used in the payload given the api_key provided was correct? Any suggestions? -

Why is my posted param not returning in my response?
I have a form that sends params correctly. I can see the values are being posted to my endpoint. However, one of the values keeps coming back "null" on my response. The value in question is for my "Litter" model. I suspect the back-end code is broken somehow (since i see the form is sending the values via my developer tools network tab) But I don't know where the flaw is. This used to be working .... until my back-end guy decided to rewrite everything...now I've been stuck trying to rewire my front-end to Mr, professors new back-end. But I digress. I won't even mention how Mr. Know-it-all handed off to me a back-end without checking if the new api endpoints actually worked (hint: they did not) You can see inside posting values for my form in my front-end file AddCat.vue in my method onSubmitted... onSubmitted() { axios.post(`/api/v1/cats/`, { name: this.name, gender: this.gender, cat_type: this.cat_type, litter: {name: this.litter, notes: this.notes}, weight: this.weight, birthday: this.birthday, weight_unit: this.weight_unit }) .then(response => { console.log("onSubmitted called:"); console.log(response); response.status === 201 ? this.showSuccess = true : this.showDanger = true; // this.profilePic = true; }) .catch(error => { console.log(error); this.showDanger = true; }) Below are the ... -

Django. Get choices from another model columns
I have two django apps: -App1 --models.py --views.py --etc.py -App2 --models.py In App1: #models.py class Table1(models.Model): field1 = models.IntegerField(default=20) field2 = models.IntegerField(default=20) etc.... In App2 I want to give users a choice selecting one of the fields in the model above, so: #models.py app2 from App1 import models as app1model choices = app1model.Table1._meta.get_fields(include_parents=False) class Table2(model.Model): select = models.Charfield(max_length=1, choices=choices) This results in a circular import error, how can I avoid this? Should I rethink the approach to the problem??
