Replace text entry for datetime to calendar date picker icon in Django form
I've this template in my Django application for adding a training session: {% extends 'base.html' %} {% load crispy_forms_tags %} {% block content %} <h1>New session</h1> <form action="" method="post">{% csrf_token %} {{ form|crispy }} <input class="btn btn-success" type="submit" value="Save" /> </form> <p /> {% endblock content %} The form contains a datetime field which appears as follows: Is it possible to change this so instead of entering the datetime as text it can be selected from a calendar type icon? If so, how is this done? This is my view: class SessionCreateView(CreateView): model = ClubSession template_name = 'session_new.html' fields = ['location', 'coach', 'date', 'details'] This is my model: class ClubSession(models.Model): location = models.CharField(max_length=200) coach = models.ForeignKey(CustomUser, on_delete=models.CASCADE) date = models.DateTimeField(default=now) details = models.TextField() def __str__(self): return self.location def get_absolute_url(self): return reverse('session_detail', args=[str(self.id)]) -

How do I Query a child value of an object in a CharField of a model?
I have a model: class OAuthCredentials(BaseModel): author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="credentials_author") temp_id = models.UUIDField(default=uuid.uuid4, editable=True) credentials = models.CharField(max_length=255, blank=True) The "credentials" CharField is an object with a token and some other info inside of it. I'm trying to authenticate the token like so: def authenticate(request, username=None, password=None, token=None, **kwargs): if token: if request.session['credentials']['token'] == token: user = OAuthCredentials.objects.get(credentials__token=token) I thought I could look inside of it to query like so: user = OAuthCredentials.objects.get(credentials__token=token) But I'm getting the error: Unsupported lookup 'token' for CharField or join on the field not permitted. How do I check my token against the token inside of the credentials object in that model? -
problems creating a modelform that validates unique_together with a foreignkey that is excluded from the modelform
So i've been stuck on this problem for a couple of days. I am trying to create a form that validates unique together with a foreignkey that is excluded from the modelform(since i dont want user to choose the user) and a "title" field which is included. What i tried to do is to define a init that takes a user object passed in through the view, to set the user field and validate inside the form. However when i save the form i get an error saying: init() got multiple values for argument 'user' My modelform looks like this class NewGoalForm(ModelForm): class Meta: model = Goal exclude = ['slug', 'date_created', 'user', 'parent'] def __init__(self, user, *args, **kwargs): self.user = user object = Goal.objects.get(user=self.user, parent=None) self.parent = object super(NewGoalForm, self).__init__(*args, **kwargs) And my view looks like this def goals(request, username): #def get(node_id): return Category.objects.get(pk=node_id) if username == request.user.username: if request.method == 'POST': userobject = User.objects.get(pk=request.user.pk) form = NewGoalForm(request.POST, user=userobject) if form.is_valid(): form.save() return HttpResponseRedirect(request.path_info) else: userobject = User.objects.get(pk=request.user.pk) form = NewGoalForm(user=userobject) user = User.objects.get(username=username) object = Goal.objects.get(parent=None, user=user).get_descendants(include_self=False) return render(request, 'goals/goals.html', {'genres': object, 'form': form, }) else: return render(request, 'goals/private.html') Any help is highly appreciated! -

Django Forn Not Saving Extra Information
I extended the Django AbstratUser so that users can use email to sign in and signup, these work perfectly. The problem I am facing, however, is that the extra information on the extended model is not storing the information in the database, even though the user gets created. Once I hit the submit button, the user and extended model get created, and while the user model stores the information, the extended model is always empty. I have tried using both signals and @transaction_atomic, yet, I have not been able to figure it out. Maybe I am missing out something, I do not know.

quickly access models attributes via foreign key relationship in django template
I have a model where one field is a ForeignKey so that each child object is linked to a parent object.

Django on Windows Server using mod_wsgi. No module named 'lxml.etree'
I am deploying a new Django project to a local Windows server via Apache with two preexisting Django projects. The site works when running locally on the server, but not via WSGI. I am using the mailmerge package to manipulate some docx templates, and when the site loads, it fails on the line "from lxml.etree import Element". I have tried modifying the import command in the mailmerge.py file to no avail. I have installed the lxml and mailmerge packages in and outside of my virtualenv. I've googled and searched this and other sites, but the search results either don't apply or didn't solve the issue when I tried the various fix actions.

Django- how to incorporate forms into ListView
Using Django, I am trying to create a view displaying a list of objects. each list will contain some details about participants in a study (name, age, etc.). That part is easy enough however for one of the fields, for each participant in this list, a drop-down menu that will display the current state of the field and then allow the viewer to select a different value for this field, and then either automatically or through hitting a 'submit' button, update that field value. Currently I am using a ListView to enable this view but I cannot make this work. I am currently trying this. : ''' class ReviewStateForm(forms.ModelForm): class Meta: model = Participant fields = ['review_state'] widgets = {'review_state': forms.Select(Participant.REVIEW_STATE_CHOICES)} def get_context_data(self, **kwargs): context = super(ParticipantListView, self).get_context_data(**kwargs) for p in context['object_list']: p.form = ReviewStateForm(instance=p) return context ''' This gives me an error when I go to the associated url due to an exception in processing 'item.form' in the template. How can I address this? I am open to using a different approach completely and not using ListView -
Why does this django query return a tuple instead of the object?
I'm working on a project and found a bug which makes no sense to me. In these lines: customer = Customer.objects.get_or_create(phone=from_number) store = Store.objects.get(phone=to_number) logging.info("CUSTOMER TYPE: {}".format(type(customer))) logging.info("STORE TYPE: {}".format(type(customer))) In the logs, the customer type says CUSTOMER TYPE: <class 'tuple'>, but the store type says STORE TYPE: <class 'orders.models.Store'>. Both classes are in the same project and app, both are included in the same way (from orders.models import Customer, Store) If it's of any help, the classes are these: class Customer(models.Model): name = models.CharField(max_length=200, verbose_name="Nombre") phone = models.CharField(max_length=13, verbose_name="Teléfono") last_location = models.CharField(max_length=200, verbose_name="Ultima ubicación") def __str__(self): return self.name class Store(models.Model): service_hours = models.ForeignKey(ServiceHours, related_name="stores", on_delete=models.PROTECT) name = models.CharField(max_length=100, verbose_name="Nombre") phone = models.CharField(max_length=13, verbose_name="Celular") enabled = models.CharField(max_length=200) address = models.CharField(max_length=200, verbose_name="Dirección") dialogflow_id_project = models.CharField(max_length=30, blank=False, null=False, default='pedidoswhatsapp-hcujca') file_settings_name = models.CharField(max_length=30, blank=False, null=False, default='pedidos_dialogflow.json') def __str__(self): return self.name I don't get how the code would be taking the customer as a tuple. Any help would be very helpful. -
Django/Python : Best practices for video storage / processing
I am building an app that allows users to upload video submissions for specific events. The video file is handled with django-videokit which uses ffmpeg and mediainfo to get the dimensions, length, mimetype, and create a thumbnail. It then sends the video to a celery task to create an mp4. I am using a digitalocean droplet, nginx, and gunicorn to serve the website. Originally, I was storing, serving and processing all the videos from the droplet. I recently moved my static and media files to a Spaces bucket and use django-storages. It seems like a sacrificed a lot of speed on the uploads for what I think is the "greater good". Can anyone provide feedback? Did I make the right decision to use the CDN? After moving to the CDN, when the file upload reaches 100% the page sits idle with the loading wheel while I assume it sends the file to the CDN? I am still relatively new and this is my first experience with video processing and a CDN -
How to handle multiple elements with the same ID in HTML/AJAX/DJANGO?
I have created the functionality to like/dislike posts in my blog but currently it is that the users can only give a like on the post_detail page. Now I wanted to improve my page so users do not have to open the post_detail view but instead can like posts on the main feed.

How to extract charts of xlsx to save on database using django
I want to know how can I extract the charts which exist in an excel file (xlsx) and save them on a database (as an image/pdf/excel chart). I am working with django and reading the other data on spreadsheet using openpyxl. I have found this question and answer but it works using win32 which clearly I can't work with on Linux cPanel. The excel file is received from a user and its certain cells are saved to database at the time of uploading. Any help is appreciated
