I how to check for authenticated user and show then show a different content in django
What am trying to do is have two different user locations. One is from my user model and the other is default from view. I want that anytime a user is authenticated, the location from the model shows but if not logged in the default location should be passed to the view. Views.py class Home(generic.TemplateView): template_name = "Home.html" def get_context_data(self, **kwargs): context = super(Home, self).get_context_data(**kwargs) if User.is_authenticated: map_location = self.request.user.location_on_the_map else: map_location = Point(longitude, latitude, srid=4326) context.update({ 'job_listing': JobListing.objects.annotate( distance=Distance("location_on_the_map", map_location) ).order_by("distance")[0:6] }) return context -
Django 403 Forbidden POST/PUT when requesting from Reactjs (strict-origin-when-cross-origin)
I have a reactjs project that makes requests using API to django-rest-framework. It was working fine and this problem suddenly appeared which is super weird. I'm already using django-cors-headers. My settings.py: INSTALLED_APPS = [ ... 'rest_framework', "corsheaders", ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', ... ] CORS_ALLOW_ALL_ORIGINS = True My reactjs request: fetch('/api/user/', { method: 'POST', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', }, body: JSON.stringify(obj) }) I just want to emphasize that it was working fine and suddenly after editing the code, it stopped working. -
how to prevent user from submitting the same form twice
I have the codes below in my views and models. But I want a situation in which a user cannot submit the same form twice. once a user submits the form he or she can only see a preview of what has been submitted but is unable to submit the same form. Any help would be highly appreciated. Thanks #views.py def index(request): form = MembershipForm() if request.method == 'POST': form = MembershipForm(request.POST) if form.is_valid(): form.save() return redirect("home") return render(request, 'index.html', {'form': form) #models.py class Membership(models.Model): fullname = models.CharField(max_length=500, blank=True, null=True) location = models.IntegerField(default='0',blank=True, null=True) department = models.IntegerField(default='0',blank=True, null=True) last_update = models.DateTimeField(auto_now_add=False, auto_now=True) def __str__(self): return str(self.fullname) -
Dynamically change Char/IntegerField choices for each Model instance
I'm wondering if it's possible to dynamically change the choices of an IntengerField for each instance of a Model. I'm working with a video game API and i want PLATFORM_CHOICES to be unique for each game, since not every game is released on the same platform. For example, on the first iteration, the platform choices for game1 could be PlayStation & Xbox, but game2 could be PlayStation, Xbox, Nintendo, & PC. models.py class TestModel(models.Model): PLATFORM_CHOICES = [] platform_type = models.IntegerField(choices=PLATFORM_CHOICES, null=True) game = models.CharField(max_length=200, null=True) api.py def get_games(self): new_url = "{}{}".format(self.url, 'games') data = requests.get(new_url, params=self.query).json() games = data['results'] for game in games: t = TestModel() for platform in game['platforms']: id = platform['platform']['id'] # int name = platform['platform']['name'] # str t.PLATFORM_CHOICES.append((id, name)) # add tuple to list t.save() t.game = game['name'] t.save() I've tried different variations of this but the IntField always ends up empty. Please let me know if there's anymore info I can provide. -
Django Rest Framework - Unable to UPDATE Table Via AJAX through PUT HTTP Method
I have a small project where I have built an API and it feeds the frontend via ajax. All the other CRUD functions work apart from UPDATE. When I use Postman, the UPDATE API works perfectly. So I'm guessing the problem is on the ajax side. I have searched for a solution to no avail. Some help on this would be highly appreciated.

Django query with foreign key- output should be from two models

Wagtail CMS how to validate the content of one page before publishing or saving it as draft
I am trying to make a page with Wagtail CMS that validates the content whenever I save/publish the page inside the admin editor. The content that I want to be validated is the content of 3 SnippetChooserPanels from within the page. Basically let's say I have these 3 snippets : SnippetA, SnippetB and SnippetC and these snippets (or Django models because that's what they really are) have the following relationships: SnippetA has one to many relationship with SnippetB SnippetB has one to many relationship with SnippetC. When the user saves/publishes the page I want to verify: that all the 3 snippet types have been chosen that there is a correct relationship between the snippets (ie SnippetC belongs to SnippetB , and SnippetB belongs to SnippetsA, or in other words the 3 snippets are joined together correctly in SQL database terms) Thank you! -
How do you initialize a Django FileField with multiple files?
I have a model that saves multiple uploaded files for a document. I was able to use the FileField widget on the form to allow for multiple file uploads. However, whenever I went to update the document object, the FileField widget would not populate with the initial data. I was finally able to figure out that I needed to set the initial data and a URL on the initial data for the widget to render appropriately. But it just wasn't working out with a list of File objects. How can I get this to work right? -
What's the best practice for requests.session sharing between requests in a Django Rest Framework web application?
Is it safe to use a global, static session to communicate with external APIs? Is there a reasonable indicator for when a session should be refreshed, or is using a session a bad idea? Background: I'm currently working through optimizing a Django Rest Framework application that is taking too long (>1.2 seconds) to get responses from a remote API. Based on their timings, and comparing it to a few run-throughs on Postman, the longest running components seem to be a combination of TCP and SSL handshake when they weren't cached (running django_cprofile_middleware against the endpoint showed a similar theme, with hundreds of milliseconds being spent on those aforementioned handshakes). I was able to get those interactions down to about the same in the application as in Postman after the first request by using a shared requests.session instead of a basic requests.get (closer to 200 ms per request). -
Django Admin can't display attributes in a model with multiple Foreign Keys to another model

This works for other classes which have a single Foreign Key attribute of the same model, however here since there's three Foreign Key attributes of the same model, I get an error: <class 'app.admin.TypeAdmin'>: (admin.E108) The value of 'list_display[1]' refers to 'icon1__name', which is not a callable, an attribute of 'TypeAdmin', or an attribute or method on 'app.Type'.

Django Admin: Model Foreignkey has null & blank = True, but using formfield_for_foreignkey in Admin makes it required
My model has a ForeignKey with null=True / blank=True, but when I try to alter an object in Django Admin I am using def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == 'parent_locale': return ParentLocaleChoiceField(queryset=models.Locale.objects.all().order_by('display')) return super().formfield_for_foreignkey(db_field, request, **kwargs) to alter how the data displays there.

How to plot data in a Jupyter Notebook when the Python kernel is executed remotely?
I have a Django application running on a remote machine and I would like to plot some data in my local browser in a Jupyter Notebook. I can work locally with the models in a Notebook but for some reason I'm unable to display chart. What could be the reason ?

Create django model instances from dataframe without server timeout
I am uploading a zipped file that contains a single CSV file. I then unzip it on the server and load it into a dataframe. Then I am creating django objects from it. This works fine until my dataframe becomes too large. When the dataset is getting too large the django server shuts down. I am assuming that this happens because every iteration in my loop increases memory and when there is no memory space left it shuts down. I am working with big datasets and want to make my code work no matter how big the dataframe. Imagine I have a df like this: cola fanta sprite libella 2018-01-01 00:00:00 0 12 12 34 2018-01-01 01:00:00 1 34 23 23 2018-01-01 02:00:00 2 4 2 4 2018-01-01 03:00:00 3 24 2 4 2018-01-01 04:00:00 4 2 2 5 Imagine that the columns could be up to 1000 brands and the rows could be more than half a Million rows. Further imagine I have a model that saves this data in a JSONB field. Thus every column is a django object, the column name being the name. The time-stamp combined with the data in the column is the JSONB field. … -

How do you add a third-party app inside your django app?
I'm currently working on a personal project. I'm working with Django but I'm not very experienced yet. I wanted to know how do you add a third party application inside you app ? Example: You have a small web-app with few pages and in one of them you want to load and use some external program e.g. Microsoft Paint. What do you need to do to add it (in general) ? Can you theoretically add any program you want or there are limits ? I would also appreciate if you could kindly show me where I can find useful documentation on this topic. Thank you ! -
modelManager get_by_natural key method change the USERNAME_FIELD affecting my authentication?

Note that the userManager inherits from BaseUserManager like this class UserManager(BaseUserManager): Can somebody explain to me what is going on here. Is the problem coming from the inheritance or the get_by_natural_key() itself ? -
auth_permission table is empty after migrate on new database
I configured a django project to use a new database. After run migrations, all tables are there, custom migrations to insert some data are ok, but the auth_permission table is empty. My project uses the permissions everywhere and is now returning Permissions.DoNotExist exception. I couldn't find if there's something in the new version of Django (updated last week), but I've done the same procedure two months ago, and the permissions were created. Now, with the Django updated, it wasn't.
