Django File Upload Not Working: Media File Missing and Full Path Issue
I'm working on a Django project where I'm trying to handle file uploads, but I'm encountering some issues. The uploaded files are missing, and I don't have the full path to the media files. Here's what I've done so far: Models I have a model with a FileField for uploads: class Article(TrackingModel): titleArt = models.CharField(max_length=200) descriptionArt = models.TextField() content = models.FileField(upload_to='articles/%Y/%m/%d') section = models.ForeignKey(Section, on_delete=models.CASCADE) is_accepted = models.BooleanField(default=False) created_by = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.titleArt Settings I'm using the following settings for media files: MEDIA_ROOT = BASE_DIR / 'media' MEDIA_URL = 'media/' URLs I've set up the URL patterns like this: from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), path('ciems_administration/', include('administration.urls')), path('auth/', include('accounts.urls')), path('', include('intelsight.urls')), ] if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) Template Here's a snippet of the template where I show the file details: <div class="container"> <h1>Report Details</h1> {{ article.titleArt }}<br> {{ article.descriptionArt }}<br> {{ article.content.url }}<br> {{ article.section }}<br> {{ article.created_at }}<br> {{ article.updated_at }}<br> <a href="{% url 'articleList' %}" class="btn btn-primary">Back</a> </div>[](https://i.sstatic.net/O9jkZnK1.jpg) Problem The uploaded file paths are shown as /media/..., but the files are not actually present in the media directory.

Is it possible to have a child model with multiple parents in a Django App?
I am creating a quiz back-end. I would like to add a feature where a user can report a question for being irrelevant or not fair. I have 3 relevant models for this in my Django app: User Model Question Model Report Model I would like to record what user created the report and also what question was reported. Is it possible to have a Many to 1 relationship between Report:User and also a Many to 1 relationship between Report:Question too? The report model would have two parents - User and Question. Is there a better way of doing this? -

Azure AppService with Django on Linux using Azure Devops for CI takes 20 minutes

Django not connecting to proper DB [closed]
I'm building a rather small backend component with Django and I got it connected to an external Postgre DB. The issue is, when I started the Django app and tried to fetch some data all I got is a 204 No content response (which is what I'd expect if there is no data in DB) but the DB has data, which make me think my app is not connecting to the proper DB. This is my DB config which was working before and is working in my deployed component: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.environ.get('DATABASE_NAME'), 'USER': os.environ.get('DATABASE_USERNAME'), 'PASSWORD': os.environ.get('DATABASE_PASSWORD'), 'HOST': os.environ.get('DATABASE_HOST'), 'PORT': os.environ.get('DATABASE_PORT'), } } There is no error showing up at all, just my DB has some test data which I can access through pgAdmin (pgAdmin result) and I also can get the data through postman calling the current deployed component (GET /api/products/ HTTP/1.1" 200 899 "-" "PostmanRuntime/7.41.0"/) -
Django as_field_group?
How can I modify the as_field_group method to change the order of its returned values? Currently, the method returns the label, error message, and then the input field. However, I want to customize it so that it returns the label first, then the input field, and finally the error message at the end. How can I either override or customize the as_field_group method to achieve this? -
How to retrieve filtered queryset used to render form fields in Django?
I have a Django form that contains a table with rows that reflect course objects from a database . Each row contains a checkbox input. This form also has some submit buttons that allow the user to filter the course objects shown in the table (besides a generic submit button). This form is used to update the users profile with courses they are interested in. When the form is submitted, courses in the filter that are unchecked should be removed from the interested M2M relation and checked ones should be added to it. To do that I need to know which inputs are checked , which I know how to retrieve, but I also need to know which courses are in the table that have unchecked inputs. Retreiving this is not as easy as ‘all the other courses in the database’ because my table does not always contain all course objects. If a user previously clicked one of the filter buttons, then the table contains only a filtered set of courses. So I need to know which courses were used to create the table at rendertime, i.e. the ones that were injected as HTML context variable. Of course I know … -

How to customize Django Oscar category_tree template tag and remove pk from category URLs?
I'm working on an eCommerce project using Django Oscar, and I've run into an issue that I can't seem to solve. My goal is to customize the category URLs to only use slugs instead of both slug and pk, but I'm having trouble implementing this. Here's what I've done so far: What I Want to Achieve: I want to remove the pk from the category URLs in Django Oscar. Right now, my URLs look like this: http://127.0.0.1:8000/category/metal-detectors_2/ I would like them to look like this: http://127.0.0.1:8000/metal-detectors/ My Setup: I'm using a forked catalogue app from Django Oscar, where I'm making my customizations. I have a custom template categories.html in which I am trying to loop through categories and their child categories. I have created a custom template tag category_tree in a templatetags folder under the catalogue app to handle category rendering. Problem: I am using the {% category_tree as tree_categories %} template tag to render categories, but it seems to be failing due to the use of pk in the URL construction. I want to modify it to only rely on the category_slug. However, I keep getting the following error: NoReverseMatch: Reverse for 'category' with keyword arguments '{'category_slug': 'metal-detectors', 'pk': … -

How to configure two server domains in django-anymail

Video Not Displaying on Vercel Deployment in Django Project (Works Locally)
I'm working on a Django project where I'm displaying a video using the tag. The video works perfectly on my local development server, but once I deploy the project to Vercel, the video does not load. Here’s the HTML code I’m using to display the video: I tried using both {{ video_url }} and the {% static %} tag to load the video file from the static/videos directory. I also ensured the video file was collected using collectstatic and updated the vercel.json file to serve static files correctly. I expected the video to load and play as it does on the local development server. However, after deploying to Vercel, the video doesn’t show up at all. No error messages are shown in the browser console. -
Django Filter __In Preserve Order
This question is regarding Django filtering, with __In clause. Basically, I am trying to understand how to filter by providing videos.filter(video__in = video_ids) with string ids, so that each row that gets returned has the same order as the order of string ids in the list used for filtering. For more context, filtering is done using string ids for e.g. ['7C2z4GqqS5E','kTlv5_Bs8aw','OK3GJ0WIQ8s','p8npDG2ulKQ','6ZfuNTqbHE8']. Model video field is video id described above. It is different from the integer id. The video_id_order used below was something I had tried that gave error Field 'id' expected a number but got '7C2z4GqqS5E', I believe this is not being used correctly, and something is still missing to get the order of results preserved as it is in video_ids. What should be the correct order function in this case or is this approach even correct with Django models to preserve query-set result when __In clause is used? def get_video_objects(video_ids,count): ''' video_ids are already in the correct order, filter should return rows in the same order ''' videos = Video.objects.all() // video_id_order = Case(*[When(id=id, then=pos) for pos,id in enumerate(video_ids)]) results = videos.filter(video__in = video_ids) // results = results.order_by(video_id_order) results = list(results[:int(count)]\ .values('video','title','comment_count','likes')) return results Video model is as following … -

How to retrieve object ids present in a form at POST request processing time
I have a Django form that contains a table with rows that reflect course objects from a database . Each row contains a checkbox input . When the form is submitted , I want to update which courses are checked and unchecked into the user profile. To do that I need to know which inputs are checked , which I know how to retrieve, but I also need to know which inputs are unchecked . This is not as easy as ‘all the others’ because my table does not always contain all course objects from the database. Its often a filtered set. So I need to know which courses are present in the table. Of course I know this at rendertime, but I dont know how to retrieve it at POST request processing time. I have been researching but am unsure about the best way to solve this problem. I read something about using hidden inputs , which I could give a try. The idea would be to give each row a hidden input with the course id, which I could retrieve when the form is submitted. I am curious if this would be the way to go. Or if … -

JQuery editable select after Ajax call in Django
I'm using JQuery editable select in a Django project to make select widgets searchable. When I'm calling another template containing selectboxes with Ajax, the script won't apply unless I use : $.getScript("https://rawgit.com/indrimuska/jquery-editable-select/master/dist/jquery-editable-select.min.js").then(() => {} The problem is that it makes the rendering of the Ajax very slow and random. Is there a way to cache the script in the parent template and load it only once so I can reuse it when I'm rendering the child template ? Here is my AJAX call on parent template : $.ajaxSetup( { data: {select_update_record_project_id: sales_documents_id , csrfmiddlewaretoken: '{{ csrf_token }}' }, }); $.ajax({ type: "GET", url: "/my_url/", cache: true, // I have tried both true and false beforeSend: function(){ $('#div_master_sales_documents_edit').empty() }, success: function (data) { $.getScript("https://rawgit.com/indrimuska/jquery-editable-select/master/dist/jquery-editable-select.min.js").then(() => { $("#div_master_sales_documents_edit").html(data); }); } }); } Here is my child template rendered after Ajax call : <select id="sales_documents_editable_select_description_1"></select> <select id="sales_documents_editable_select_description_2"></select> <select id="sales_documents_editable_select_description_3"></select> <script> // this is where you apply the editable-select to select widgets var list_selectbox_ids = ['sales_documents_editable_select_description_1','sales_documents_editable_select_description_2','sales_documents_editable_select_description_3']; for (let i = 0; i < list_selectbox_ids.length; i++) { $('#' + list_selectbox_ids[i]).editableSelect({effects: 'fade'}).on('select.editable-select', function (e, li) { populate_sales_documents_selected_product($('#' + list_selectbox_ids[i]).attr('id'), li.text(), li.val()) }); } </script> -
How to handle multiple products in a sale with instalment payments in Django/MySql?
I'm building an inventory management system using Django where clients can purchase multiple products in different quantities as part of a single sale. The client may also pay for the sale in installments, rather than paying for each product individually. Current Tables/Models: Client: Records first name last name and the type of the client (e.g enterprise or regular person). Product: Records name and stock unit that describes the quantity of this product and a description of the item. Sell: Records sales. Buy: Records product buyings (e.g restocking) Payment: Records client payments. The issue: I need a way to: Allow the client to make payments in installments for the total sale price. Update the status of the sale ("pending" or "completed") based on whether the client has fully paid for the sale. Track the whole sale instead of relying on each product. Current models: class Product(models.Model): name = models.CharField(max_length=150) description = models.TextField() stock_unit = models.PositiveIntegerField() created_at = models.DateTimeField(default=timezone.now) numero_bl = models.CharField(max_length=30,null=True, blank=True) def __str__(self): return self.name # ----------------------------------------------------------- class Client(models.Model): CLIENT_TYPE_CHOICES = [ ('particulier','Particulier'), ('entreprise','Entreprise'), ] first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) client_type = models.CharField( max_length=20, choices=CLIENT_TYPE_CHOICES, default='particulier' ) created_at = models.DateTimeField(default=timezone.now) def __str__(self): return f"{self.first_name} {self.last_name} ({self.client_type})" # ----------------------------------------------------------- class … -
