How to check for a substring in Django update_or_create() method?
Let's say I have the following object that I want to push to my database using the according model: Object { 'object_name': 'Foo', 'value': 100,00 } and want to update the value of Foo Bar in the database. How to make Django check for Foo being a substring of a database object (in this case Foo Bar) to avoid duplicates? obj, created = foo_model.objects.update_or_create( object_name=object_name, defaults={ 'value': value, } ) (so the goal is to update the value of the object Foo Bar instead of creating a new object Foo since it is a substring of an already existing object). -

Adding user restrictions on who can edit posts in Django
I'm trying to add restrictions on my site so that only the person who added a product or post can edit/delete that product or post. Currently, the edit button is visible to anyone so it's not ideal. I've had a good crack at it, but something is still wrong as the edit button still shows up even when I'm not the post creator. The edit_forum_post view I've created: @login_required def edit_forum_post(request, post_id): """ Create a view that allows us to edit a post """ post = get_object_or_404(Post, pk=pk) registered_user = request.user.id creator = post.creator.id if not logged_user == creator: messages.error(request, 'You are unable to edit this post') return redirect('get_forum') if request.method == "POST": edit_post = ForumPostForm(request.POST, request.FILES, instance=post) if edit_post.is_valid(): edit_post.save() messages.success(request, 'You have successfully updated your post') return redirect('forum_post_details', post_id) edit_post = CreatePost(instance=post) context = { 'form': edit_post, 'post': post } return render(request, 'forum_post_form.html', context) The clause I have added onto the Edit post button: {% if registered_user == post.creator %} <a href="{% url 'edit_forum_post' post.id %}" class="btn btn-outline-warning">Edit Post</a> {% endif %} Any feedback is greatly appreciated! -
How to enable logging for deployed Django app running on GAE (Google App Engine)

How can i use MongoDB with Django 3.0?
I've always been using MongoDB on my Django project, but now that i updated my Django version to 3.0, i can no longer make queries to my database. Every time i try to make a query, my code will just freeze. I tried to update my Djongo version, but every time i do it, my Django version will be downgraded to Django 2. I made some research and found that Djongo has compatibility problems with Django 3. However, on the github repository i'm seeing support for django 3.0. Can i use it with Django 3.0, then? And if i can't, is there any way to use MongoDB without Djongo and without having to change my whole code? -
Having trouble with Serializing a Project and Images (Images don't show up in the api view list)
I am very new to Django and decided to create a project to increase my skills/gain experience. I'm having trouble with images link or name not showing up in the api view list using Django-rest-framework. As seen below api_view So far I was able to create two models one that contains the project information and another model that allows multiple images to be associated with the project. model You can upload the images through the admin page. As seen below admin_page I think the main culprit is my serializers and the way it was setup. serializers Here is my view if it helps view (The red underline is from my linter thinking there is an error) Any help will be appreciated! Sorry if I the way the question was phrased was weird (need to work on asking the right question) -
How Does Django Createsuperuser Know How To Parse My Date Field
I created a customized User module that adds a few extra fields: class User(AbstractUser): """User modle for staff, clients and customers""" username = None # remove username from the model email = models.EmailField("email address", unique=True) # """Email of user this will be used for login""" address = models.OneToOneField(Address, on_delete = models.PROTECT, null=True, blank=True) """:class:`Postal Address` associated with the User""" birth_date = models.DateField() """Date of birth of User""" phone = models.CharField(max_length=15) """Phone number of User""" org = models.ForeignKey(Organization, on_delete=models.PROTECT, null=True, blank=True) """:class:`Organization` User is associated with""" # changes for using email instead of username USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name', 'birth_date', 'phone'] objects = UserManager() def __str__(self): return F"{self.email} {self.first_name} {self.last_name}" When I ran the createsuperuser command it asked me for birth_date (and knew how to parse it). I entered 2020-01-01 for the value. Curious, I then temporarily put these statements in the createsuperuser function: print("*****") print(extra_fields) print("*****")``` and got: {'first_name': 'super', 'last_name': 'user', 'birth_date': datetime.date(2020, 1, 1), 'phone': '12345', 'is_staff': True, 'is_superuser': True, 'is_active': True} How did it know to use datetime.date and how to parse it correctly? More importantly, how can I make similar behavior for a custom related object? -
Django annotation with filter ignoring primary key resutling in too many annotated items

DRF- Error when creating a new instance in an M2M through model
I have the following two models: class User(models.Model): user_id = models.CharField( max_length=129, unique=True, ) user_resource = models.ManyToManyField( Resource, through="UserResource", ) occupation = models.CharField(max_length=100, default='null') def __str__(self): return self.user_id and class Article(models.Model): uuid = models.UUIDField(editable=False, unique=True) company = models.ForeignKey( Company, on_delete=models.PROTECT, related_name='article_company_id', ) articleType = models.ForeignKey( ArticleType, on_delete=models.PROTECT, related_name='type', ) date_inserted = models.DateField() def __str__(self): return self.uuid which are modeled with a many-to-many relationship, using this through model: class UserArticle(models.Model): user = models.ForeignKey(User, to_field='user_id', on_delete=models.PROTECT,) article = models.ForeignKey(Article, to_field='uuid', on_delete=models.PROTECT,) posted_as = ArrayField( models.CharField(max_length=100, blank=True),) post_date = models.DateField() class Meta: db_table = "core_user_articles" Here's my view: class BatchUserArticleList(mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView): queryset = UserArticle.objects.all() serializer_class = BatchUserArticleSerializer def create(self, request, *args, **kwargs): serializer = BatchUserArticleSerializer(data=request.data) if not serializer.is_valid(): return response.Response({'Message': 'POST failed', 'Errors': serializer.errors}, status.HTTP_400_BAD_REQUEST) self.perform_create(serializer) # equal to serializer.save() return response.Response(serializer.data, status.HTTP_201_CREATED) def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) The problem I'm facing is when I want to POST data, of the following format, in the M2M table: { "posted_as": ["news"], "post_date": "2020-05-26", "user": "jhtpo9jkj4WVQc0000GXk0zkkhv7u", "article": [ "11111111", "22222222" ] } The above contains a list of many articles so I used a custom field in my serializer in order to extract each article, create a new UserArticle object … -
Is there something wrong with the way I am calling .makedsn or .cx_Oracle?
My errors consistently point to the cx_oracle line, but I don't see where my code is wrong. I'm working on a remote server, which is why I haven't found much help on other posts about the same error. Any help would be appreciated. Error message : "ORA-12541: TNS: no listener" My code snippet: try: dsn_Oracle = cx_Oracle.makedsn(queryset.first().Host, queryset.first().Port, queryset.first().Database) conn_Oracle = cx_Oracle.connect(queryset.first().UserID, queryset.first().Password, dsn_Oracle) c = conn_Oracle.cursor() except DatabaseError: connected = False self.message_user(request, "Failed to connect.") else: connected = True self.message_user(request, "Succesful connection!") conn_Oracle.close()
