Extending Django's nav-sidebar with additional options
I am working with Django and currently trying to add options to default nav-sidebar which will not be anyhow connected with models, but will open other additional pages. The best idea i got is to extend the default base_site.html with my new option for a sidebar. Therefore i resulted in the following code: {% extends "admin/base_site.html" %} {% block sidebar %} <div class="app-dashboard module current-app"> <h2>Custom Options</h2> <ul> {% include "admin/custom_sidebar.html" %} </ul> </div> {{ block.super }} {% endblock %} custom_sidebar.html: <th class="model-group"><a href="{% url 'email' %}">Send message</a></th> This indeed extends the page, but adds my option to the bottom of the content block, whereas I want it to appear in my sidebar. Here is how it looks: I understand I practically didnot affected the default nav_sidebar anyhow, but I am out of ideas how to make it. Is there a way i can modify a nav_sidebar in django? And if so how shall i do it? -

Django: Starting a celery worker when a button is clicked
I have a button which puts a PCAP file into a parsing function. When my button is clicked "Upload File" it calls my form_upload view and I want my celery task to start running so it displays a progress bar while the file is being parsed. However, when clicking "Upload File", the page loads and then the celery starts. So the progress bar does not display until after the page loads and the function finishes parsing. Here is my index.html <form action="{% url 'upload' %}" class="row gy-1 gx-2 align-items-center" id='startIDS' method="post" enctype="multipart/form-data" style="margin-bottom: 10px;"> <div class='col-auto'> <input class="form-control" type="file" name="file"> </div> <div class='col-auto'> {% csrf_token %} <button type="submit" class="btn btn-primary btn-sm" style="float: right;" onclick="wait()">Upload File</button> <script> function wait() { //go_to_sleep.delay(5); alert("Click Ok and then please wait for upload to finish"); } </script> </div> <div class='progress-wrapper'> <div id='progress-bar' class='progress-bar' style="background-color: #68a9ef; width: 0%;">&nbsp;</div> </div> <div id="progress-bar-message">Waiting for progress to start...</div> <div id="celery-result"></div> <script src="{% static 'celery_progress/celery_progress.js' %}"></script> <!--CELERY--> {% if task_id %} <!-- avoid any errors by just checking if the task_id exists --> <script> // JQuery document.addEventListener("DOMContentLoaded", function() { var progressUrl = "{% url 'celery_progress:task_status' task_id %}"; CeleryProgressBar.initProgressBar(progressUrl); }); </script> {% endif %} </form> Here is my views.py `# Render … -
Django returns a tuple instead of returning data
I have a simple model that is supposed to store some basic nutritional information about food, but whenever I create or edit the model it returns a tuple instead of the data. The app is simple and these are the only models I have in them. Here is the model: class User(AbstractUser): test_field = models.CharField(max_length=100) def __str__(self): return self.username class Food(models.Model): name = models.CharField(max_length=100, null=False, blank=False), calories = models.IntegerField(default=0, null=False), protein = models.IntegerField(default=0), fat = models.IntegerField(default=0), rel_user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) At first I thought it was an issue with how I was saving the model, so I tried creating one through the shell with the following commands: from api.models import User, Food f = Food() f.name = "Test" f.calories = 1 f.rel_user = User.objects.get(id=1) f.save() If I call f.rel_user, it returns myemail@gmail.com, but if I call f.name, it returns (<django.db.models.fields.CharField>,). In order to try to fix this, I've looked through the getting started project on https://docs.djangoproject.com/en/4.2/intro/tutorial01/, and have made sure that my settings.py, and my models are written like the ones on the site. I've tried using both the shell and a form to create test Food objects. How can I fix this so when I try to get … -

Django: How to loop through query set and change the boolean field to True in django?
I am trying to loop through a queryset in django and turn all the boolean fields in the queryset to true. I want to turn this booleans to True on the success_page, so i tried doing it like this @login_required def PaymentSuccessView(request): ... order = get_object_or_404(CartOrder, stripe_payment_intent=session.id) cart_order_items = CartOrderItem.objects.filter(order=order) for c in cart_order_items: c.paid = True c.save() return render(request, "payment/payment_success.html", {"order": order}) The problem is that, this still does not work even after i get redirected to the success page on successful transaction. I also tried doing this in the model, i am not sure if it's the right way to do this, but i tried it and it still did not work class CartOrderItem(models.Model): order = models.ForeignKey(CartOrder, on_delete=models.CASCADE) vendor = models.ForeignKey(Vendor, on_delete=models.SET_NULL, null=True) paid = models.BooleanField(default=False) .... def save(self, *args, **kwargs): if self.order.payment_status == "paid": self.paid = True return super(CartOrderItem, self).save(*args, **kwargs) These are my model fields class CartOrderItem(models.Model): order = models.ForeignKey(CartOrder, on_delete=models.CASCADE) vendor = models.ForeignKey(Vendor, on_delete=models.SET_NULL, null=True) paid = models.BooleanField(default=False) ... class CartOrder(models.Model): vendor = models.ManyToManyField(Vendor) buyer = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, related_name="buyer") stripe_payment_intent = models.CharField(max_length=200,null=True, blank=True) -

How to create a constraint on a field and the date value of created_at in django?
I want to create a constraint that allows an instance of a value for a field to exist only once per day. Meaning if I have a column custom_id and a created_at field, an example value '1' of custom_id can only exist once on 2023-01-01, so adding another field will fail. I am using postgres as a database and from what I have gathered, a query similar to EXCLUDE USING gist (custom_id WITH =, date_trunc('day', created_at) WITH =) However I am failing to replicate this in a django model according to the available -
imported a populated table on to postgresql but I need the model in Django . What to do?
I have a set of populated tables (country,region town etc) that I have imported onto Pgadmin (postgresql) but I need the models in Django now so that I can work on those tables. However, like I said, these were tables with data, so if I write the model definition in Django, it will either destroy my tables by overwriting them (leaving them empty) or it will give an error. I prefer to work now with models, but can't create them because the tables already exist. What can I do? I know you could say, well, you should have first defined the models. Well, no, because the three tables are linked by multiple composite primary keys and actually I got the code for the model once the tables have been imported to the pgadmin, and the model definition was quite complex. If you are curious to see how a model definition looks here it goes: ` class Localidades(models.Model): id_localidad = models.AutoField(primary_key=True) id_region = models.SmallIntegerField() id_pais = models.SmallIntegerField() id_idioma = models.SmallIntegerField() nombre_localidad = models.CharField(max_length=150) x = models.FloatField() y = models.FloatField() exacto = models.SmallIntegerField() class Meta: managed = False db_table = 'localidades' unique_together = (('id_localidad', 'id_region', 'id_pais', 'id_idioma'),) ` I did not even … -

Is there any visible error in the code? models.py class ObjetArchi(models.Model): id = models.AutoField( primary_key=True, ) materiau = models.ForeignKey( 'Materiau', on_delete=models.SET_NULL, related_name='objets_archi', blank=True, null=True ) class Materiau(models.Model); id = models.AutoField( primary_key=True ) nom = models.CharField( max_length=125, blank=True, null=True ) views.py class NoticesListView(ListView): model = ObjetArchi template_name = 'notices/index.html' context_object_name = 'liste_notices' paginate_by = 20 def get_queryset(self): qs = super().get_queryset() materiau = self.request.GET.get('materiau__nom') if materiau: qs = qs.filter(type=materiau) return qs def get_context_data(self, **kws): context = super().get_context_data(**kws) context['materiaux'] = ( self.get_queryset() .values('materiau__nom') .annotate(count=Count('id')) ) return context urls.py urlpatterns = [ path('', views.NoticesListView.as_view(), name='notices_list'), ] notices/index.html {% for materiau in materiaux %} <ul> <a href="?materiau={{ materiau.materiau__nom }}"> {{ materiau.materiau__nom }} ({{ materiau.count }}) </ul> {% endfor %} {% if liste_notices %} <ul> {% for notice in liste_notices %} <li><a href="{% url 'notices:detail' notice.id %}">{{ notice.titre }}</a></li> {% endfor %} </ul> {% else %} <p>Aucune notice n'est accessible.</p> {% endif %} -
django formset with initial data is not showing the Files
So im using a django formset to show multiple instances of a model and i have a file field in this model. the problem is when i add a file and save it, it's not being shown in frontend part. this is the form: class ProductForm(forms.ModelForm): class Meta: model = Product fields = ( "name", "description", "related_file" ) widgets = { 'description': forms.Textarea(attrs={'rows':4, 'cols':10}), } the formset: ProductFormSet = formset_factory(ProductForm) and view: class ProductView(LoginRequiredMixin, TemplateView): template_name = 'pages/account/products.html' success_url = reverse_lazy('account:products') page_name = 'products' page_title = _('Products') crumb = _('Products') def render_to_response(self, context: Dict[str, Any], **response_kwargs: Any): formset = ProductFormSet( initial=self.request.user.company.products.all().values()) context['formset'] = formset return super().render_to_response(context, **response_kwargs) to test i used these tags in my html file: {{formset.0.initial}} {{formset}} and this is the result: as you can see the initial data is there, and also filled other inputs correctly, but it did not fill the filefield data. -
How to move items between lists in Django
Beginner and fairly new to Django here, I have two Django models and I would like to move an item(s) from one to the other. I am using lists to store the items, but for some reason I can't quite figure out why when I try to remove the item from one and move it into the other it is remaining in the previous list. Here is my code: views.py def profile(request): playinglist = Playinglist.objects.filter(user=request.user.username) playinglist_items = [] playing = 0 present_in_playinglist = False if playinglist: for item in playinglist: try: game = Game.objects.get(id=item.game_id) playinglist_items.append(game) present_in_playinglist = True playing += 1 print(playinglist_items) except: present_in_playinglist = False playedlist = Playedlist.objects.filter(user=request.user.username) playedlist_items = [] finished = 0 present_in_playedlist = False if playedlist: for item in playedlist: try: game = Game.objects.get(id=item.game_id) playedlist_items.append(game) present_in_playedlist = True finished += 1 playing -= 1 playinglist_items.remove(game) except: present_in_playedlist = False models.py class Game(models.Model): title = models.CharField(max_length=200) description = models.TextField(blank=True, null=True, max_length=500) image = models.URLField(blank=True, null=True, max_length=500) genre = models.CharField(blank=True, null=True, max_length=200) platform = models.CharField(blank=True, null=True, max_length=200) developer = models.CharField(blank=True, null=True, max_length=200) publisher = models.CharField(blank=True, null=True, max_length=200) added_by = models.CharField(max_length=64) def __str__(self): return f"ID# { self.id }: { self.title }" class Playinglist(models.Model): title = models.CharField(max_length=200) user = models.CharField(max_length=64) … -
Slug Error / No Reverse URL for manually uploaded data
I have a slug defined in my model as follows: slug = models.SlugField(blank=True, null=True) def save(self, *args, **kwargs): if self.slug is None: self.slug = slugify(self.name + "-" + self.city + "-" + self.state) super().save(*args, **kwargs)``` The issue I'm having is when I bulk upload to the database via CSV I have to manually go in and re-save each business for the slug to save/populate. I would like to be able to simply upload the csv with the slug pre-populated (slug field with formatting is already in the csv). Can I format the slug manually or does this need to be done via the save method in the models.py file? -
Wagtall - template class for blocks StreamField
I have a Strucktblock: # blocks.py class GameBlock(StructBlock): logo = ImageChooserBlock(required=True) image = ImageChooserBlock(required=True) heading = CharBlock(required=True, max_length=50) description = CharBlock(required=True, max_length=100) url_button = URLBlock(required=True) class Meta: icon = "form" template = "blocks/game_card.html" How can I wrap one or more blocks in a template into its own class? For example: <div class="row-grid"> <div class="card">Card1</div> <div class="card">Card2</div> </div> I tried a template: {% for block in page.body %} {% if block.block_type == 'game' %} <div class="row-grid">{% include_block block %}</div> {% else %} {% include_block block %} {% endfor %} And I did: <div class="row-grid"><div class="card">Card1</div></div> <div class="row-grid"><div class="card">Card2</div></div> -
