Django model setup on existing Oracle table
I have a particular situation which I need help clarifying. I have an existing Oracle table with an auto increment ID as a primary key I am creating a django model to sync with that table so i can make use of django's ORM methods such as save(), filter() etc. I read from the django docs the .save() method can perform both a UPDATE and INSERT depending on if the values passed to the primary key results in a True value (i.e. not a None or null). In my table I have two columns which together will form a composite primary key. If I specify primary_key = True on the two attributes on the django model, do I need to remove the primary key tag from oracle table? Also, do i need to specify the unique_together to tell the django model that they are unique or will it be able to derive the index i created in the django oracle table? Thanks. -
Is there any method to connect Vue JS and Django together without using Django REST API
I am a newbie to programming world. I know how to integrate Vue JS and Django by creating the Django REST API and Vue JS(with Axios). Is there any other way I can use the Django and Vue JS together ? Because I felt it hard to make a secure Django Rest API but normal Django templating system comes with in build user authentication and creating web app is super easy. I have used normal Django templating system and added Vue JS through CDN links, it works fine for each page. My real intention was to create a website that do not reload when user clicks each page. Do you recommend AJAX for this purpose ? -

How to send email to official account from logged in user in django?
I am trying to send email from the user who is logged in to an account which I have given bilalkhangood4@gmail.com. But I have typed it manually. There could be more accounts means more users from which I want to send. But how could I send email from just those users who are logged in?

What is the difference between using brackets "[]" and parentheses "()" for "fields" in django-rest-framework
I have seen fields in the django-rest-framework initialized/declared with parentheses () and brackets [] and I am wondering if there is a difference. I have only been using () but I see [] in the documentation everywhere. Say we have a model Dog. class Dog(models.Model): favorite_food = models.CharField(max_length=255) Now would it be correct to say that these two serializers below for this Dog model are the same? Even though the field is declared with different ASCII characters. class DogSerializer(serializers.ModelSerializer): class Meta: model = Dog fields = ('id', 'favorite_food') class DogSerializer(serializers.ModelSerializer): class Meta: model = Dog fields = ['id', 'favorite_food'] -
How do you create a deferred field if your field is a SerializerMethodField?
I want to create a deferred method field in a model serializer using drf-flexfields. I am using Django Rest Framework and drf-flexfields. I want to create a method field in my model serializer to make a complex query. Because retrieving this field will incur extra database lookups, I want this to be a deferred field, i.e. it will only be retrieved if the client specifically asks for it. The DRF-Flexfields documentation seems to infer that a field can be deferred by only listing it in "expanded_fields" and not in the normal "fields" list, but gives no further explanation or example. https://github.com/rsinger86/drf-flex-fields#deferred-fields I have tried creating a simple SerializerMethodField to test this: class Phase(models.Model): name = models.CharField(max_length=100) assigned = models.ManyToManyField(settings.AUTH_USER_MODEL, blank=True, related_name="phases_assigned") class PhaseSerializer(FlexFieldsModelSerializer): assignable_users = serializers.SerializerMethodField("get_assignable_users") expandable_fields = { 'assignable_users': (UserSerializer, {'source': 'assignable_users', 'many': True}), } class Meta: model = Phase fields = ['name', 'assigned'] def get_assignable_users(self, phase): return User.objects.all() I get the following error : "The field 'assignable_users' was declared on serializer PhaseSerializer, but has not been included in the 'fields' option." What is the correct way to go about accomplishing this? -

How to change hidden-input value then send it using django forms?
Good evening, I have a problem with ajax in django forms, it refuses to change value of a hidden input send the views.py class. The page configuration.html contains a form that selects number of parameters. In addition, i need to create a new variable using the previous ones called list_items that changes its value according to the selected parameters, to send it i used a hidden input tag <input id="combo" name="combinaison" class="btn btn-success col-lg-12" type="hidden" value="test"> The variables are send to views.py but the problem is that the value of the hidden input doesn't changed, it always shows the default value. I tried using document.getElementsByName("combinaison").value = list_items; in the form but the value never changes.

How do I dynamically set timezones in Django?
So I have been creating a simple site where I need to display the timezones of the time a post was created. So far I have set it to Victoria, Australian time, because it is my timezone, but I want people from other countries to have their own timezones on the posts. I know it sounds silly, but I tried to add multiple timezones to the TIME_ZONE variable in settings.py, but I learnt that does nothing but cast errors. LANGUAGE_CODE = 'en-us' TIME_ZONE = 'Australia/Victoria' So when I put multiple timezones in, I expected it to dynamically show the time based on where you are, but it didn't, I just got a syntax error. -

vscode debug suite all of a sudden can not find Django module
I've had my vscode integrated with my Django project perfectly fine for about a month now. I went home for the weekend and all of a sudden this morning my vscode debug suite is not working.

Can i render VueJS with Django?
I would like to add Vue to my Django project, but i'm having troubles understanding some parts of it. At the actual moment, my project already has a bunch of templates and views. Everything is rendered by the views, the only JS i'm using is for Jquery. The need to add Vue comes to improve my UI. I don't need Vue to be my frontend, i only want to add some Vue components to my templates here and there. After making some research, i found about the Webpack + Vue approach. It's not the right approach for my project since it should be used for a project where the frontend is entirely built on Vue and is divided from the Django backend, so it is not the right way for me. At this point, the only way to go would be to add it using the CDN on my django html template: <script src="https://cdn.jsdelivr.net/npm/vue@2.6.0"></script> Would this approach be possible? -
Django User OnetoOneField Form - Fails Validation

How to Pass Parameters to View When Form Is Valid
I have a view which renders a form where all lines of 'manifest' information are displayed after a user selects an order # from a dropdown and submits. This form should allow for the user to enter a new line, and after doing so (and refreshing) the view should display the form again but with that updated line. My problem is that my view consumes a parameter 'Reference_Nos' from the dropdown that initially displays the view and form. After a user enters a new value, that dropdown isn't used again so the view doesn't display the correct info.
