My Html Table footer doesn't render correctly
I'm trying to create a simple table. I would like a footer with only one cell but I don't know why it's divided in two. Any idea? <table class="table-cart-view-producer"> <thead> <tr> <th>Produit</th> <th>Quantité</th> <th>Prix</th> </tr> </thead> <tfoot> <tr> <th> Prix Total du Panier : <strong>{{cart_price}}€</strong></th> </tr> </tfoot> <tbody> {% for item in cartitems %} <tr> <td>{{item.stock_item.product_stockitem.name}}</td> <td>{{item.quantity}} {{item.stock_item.product_stockitem.unit}}</td> <td>{{item.get_total_price}}€</td> </tr> {% endfor %} </tbody> </table> It renders this way: -

Django - Problem with Model Manager - Query
I'm still a beginner and I'm stuck in a challenging spot for me. I can't get data from a foreign key table to be inserted "correctly" into a column of a ListView. I basically want to create a list view of a table (FeatureFilm). This also works. But in one column I get information from another table and here I get data, but not the one that belongs to the particular table row. Here are my models. The table I want to show is "FeatureFilm" model. This model is inherited from my base Project class "ProjectBaseModel". Then there is another table "CompanyInvolved Model". This is attached to the FeatureFilm table with a foreign key (feature_id). So movies are stored (FeatureFilm) and different companies are involved in the creation process of the movies. (CompanyInvolved) class ProjectBaseModel(models.Model): title = models.CharField("Titel", max_length=100, blank=False, unique=True) leading_postproduction_id = models.ForeignKey( Company, verbose_name="Federführende Postproduktion", on_delete=models.SET_NULL, blank=True, null=True, ) phase = models.CharField(choices=post_phase, max_length=30, blank=True, null=True) former_title = models.CharField("Titel, ehemalig", max_length=100, blank=True) title_international = models.CharField( "Titel, international", max_length=100, blank=True, null=True, unique=True ) class FeatureFilm(ProjectBaseModel): class Meta: verbose_name = "Kinofilm" verbose_name_plural = "Kinofilme" ordering = ["title"] class ProductionManager(models.Manager): def get_production(self): return ( super() .get_queryset() .filter(company_role="Produktion", is_production_list=True) .values_list("company_involved__name") ) class CompanyInvolved(models.Model): … -

Django Rest Framework - Why is serializer.data giving me an empty result set but printing the serializer shows me the data
I have created a view to search posts based on their body text. I added a breakpoint to the view and I tested it with mutliple search terms and it works. The problem I have is when I do a print(serializer) in the console then I see the data of all the posts it found. But doing a print(serializer.data) gives me body:null in the data object in the front end console and an empty dictionary in the back end console. Why am I getting body: null?

Django URL dispatcher - Try next view
Alright, let me give you guys an example; We have the following url configuration in Django. Django will try to match the url with the rules down below. Once it finds a match, it will use the appropriate view and lookup the object in the model. The thing is, once it finds a match in the URL pattern, it will match the view. But once the object in the view can't be found, it will return a page not found (404) error. #urls.py from django.urls import path from . import views urlpatterns = [ path('articles/<slug:category>/<slug:editor>/', views.articles_by_editor), path('articles/<slug:category>/<slug:theme>/', views.articles_by_theme) ] We have the following url patterns, we can sort articles either by the editor or by theme. We do this to create a logical url structure for SEO purposes. Is their any way we can redirect to another view once the object isn't found? Can we modify the dispatch method to return to the url patterns and find the following matching rule? Your help will be much appriciated. Kevin -

How can I get return value from A class to class B in python?
class InputForm(forms.Form):ㅤ attachment = forms.FileField() class View1(FormView): template_name = 'main.html' form_class = InputForm def post(self, request) : I_want_this_file = request.FILES.get('attachment') return I_want_this_file class View2: blar blar ..... When there's this structure, Is there any way to get the value of I_want_this_file from a class called View2? I understand that I have to hand over the parameters to get the return value. But I couldn't bring it because of the "request". When a user uploads a file from a template called main.html, I want to take the file itself, put it in the return value I_want_this_file, and bring the file itself to View2. I have to bring that, but it's not my personal project, so there's no other way to add a file field than this. I'd appreciate it if you could help me. -

How to detect the Android foldable/flip phone in Djagno
My project displays templates separately from PC/tablet and mobile. views.py ... from django_user_agents.utils import get_user_agent ... class indexView(View): def get(self, request, *args, **kwargs): ... user = get_user_agent(request) if user.is_pc or user.is_tablet: template_name = 'web/index.html' # for PC and Tablet else : template_name = 'mobile/index.html' # for Mobile ... However, Galaxy z fold 4 is recognized as tablet when folded and opened in the Chrome browser. In Samsung's basic browser, when folded, it is displayed as a mobile template. When I checked the userAgent, it included "Safari" instead of "Mobile Safari" in the Chrome browser. Mozilla/5.0 (Linux; Android 13; SM-F936N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/109.0.0.0 Safari/537.36 When the foldable phone is folded, I want to display it as a mobile template on the cover screen in the Chrome browser. Is there a way to detect a foldable phone in Django? Or if you have another good idea, please recommend it :) -

ReactJs Url is changing on its own on api call
I am hitting an api using my ReactJs application. My code is as follows export const getCustomers = (filters) => { return createAction({ type: GET__CUSTOMERS, action: async () => await axios.get(`${BASE_URL}/customers${filters}`, { data: {}, headers: HEADERS.AUTHENTIC(), }), }); }; In the above code, we can see that in the url -> '${BASE_URL}/customers$' , 'customers' is hard coded, but whenever I am running it actually, it hits the as 'Customers'. The case of c changes on its own. It is nowhere in my application. The same problem is with other routes as well. What can be the possible issue and solutions? I hard coded the api to find the issue but it persists. -

Django cannot display a PDF inline on a web page using <embed> or <object> or <iframe> tags
I am trying to embed a PDF into a web page in Django. This is the message I see in the console: Refused to display 'http://127.0.0.1:8000/' in a frame because it set 'X-Frame-Options' to 'deny'.

However even with this code I am still getting the message shown above (in the console). I did clear my cache and do a reload, and also tried Ctrl-Shift R as well. No change. Can anyone tell me what I am missing? Is there something additional needed in settings.py? I have not tried deploying this to a testing server on the web to see if it just my local testing environment. -
