Django: Trying to update an object based on selection by a checkbox in a list display
In the template I am displaying a list of objects in a table. Since its a list I did not use a form. I then added checkboxes to approve each entry (as shown below) The problem is that now I cannot figure out how to iterate over the checkboxes. template.html <form method="post" > {% csrf_token %} {% for row in row_list %} <tr> <td><input type="checkbox" name="result" value=""/></td> <input type="hidden" name="task_id" value="{{ row.id }}"/> <td>{{ row.id }}</td> <td>{{ row.name }}</td> </tr> {% endfor %} <tr> <td colspan="5"> <button type="approve">Approve</button> </td> </tr> views.py def review_results(request, batch_id): batch = get_object_or_404(Batch, pk=batch_id) if request.method == 'POST': # I have tried the following print("Result is ", request.POST.getlist('result')) print("Result is ", request.POST.getlist('task_id')) print("Result is ", request.POST.lists()) request.POST.getlist('result')) returns the value of checkboxes which are checked (array size is 0 if nothing checked). request.POST.getlist('task_id')) returns the list of ids as originally passed (fine). But both lists are out of sync. I cannot use the array from 'result' and perform a save on the appropriate 'task_id' Any ideas on how should i fix this ? Thank you in advance. -

Django Forms CheckboxInput on Y/N String field in existing database
I'm relatively new to Django, and I'm making a form which I'm connecting to a existing MySQL database. What I'm trying to do is create a maintenance page for countries. One of the fields in my database is eu_member_state. What I'm trying to do here is create a checkbox for this field, so I can uncheck it for the United Kingdom which recently got out of the EU. class CountryForm(forms.ModelForm): class Meta(): model = Countries fields = '__all__' widgets = { 'eu_member_state': forms.CheckboxInput() } The checkbox does appear on my form, but how can I make this talk to my database? How can this checkbox only be checked when the database value is 'Y', and how do I write this back to my database on save, so 'Y' when checked and 'N' when unchecked? -

Filter objects based on th current user django model admin
Hello I am trying to filter objects in model inline admin based on a field in Profile models I have created with a OneToOneField with User the profile model has a field branch so I want to filter objects based on the logged-in user with respect to their branch class ProductDetailInlineAdmin(admin.StackedInline): readonly_fields = ('created_date', 'generated_url') model = ProductDetail extra = 1 def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "product": kwargs["queryset"] = ProductDetail.objects.filter( product=request.user.profile.branch_id) return super().formfield_for_foreignkey(db_field, request, **kwargs) the product foreignkey still returns everything without filtering out the branch. How do I accomplish the filtering? -

django create/save form using two models with a manytomany relationship
I'm less than 7 days into my Django journey - so please forgive me. I'm in a rout, requiring a bit of expert guidance - having researched/attempted to solve my problem for 10 thankless hours. Code examples are starting to look like hieroglyphics. In essence, how do I build a simple form where you can concurrently create a list and product? I have two rudimentary models a "list" and a "product". class Product(models.Model): name = models.CharField(max_length=100) url = models.URLField() price = models.DecimalField(max_digits=8, decimal_places=2) class List(models.Model): name = models.CharField(max_length=50) description = models.CharField(max_length=100) category = models.CharField(max_length=50) products = models.ManyToManyField(Product) I have this error: ValueError: 'core_lists.Product' has no ForeignKey to 'core_lists.List'. The above error surely does not restrict inline_formfactories to ForeignKey ones? Having researched this - I am not intelligent enough to merge the various sources into one cogent code block: Great article with a similar pizza and topping analogy Should I just ignore inline_formfactories and loop through everything i.e. the opposite recommendation Wtf is super mixin and **'s in front of parameters forms.py class ProductListForm(ModelForm): class Meta: model = Product class ListForm(ModelForm): class Meta: model = List fields = '__all__' list_form.html <form method="POST" action=""> {% csrf_token %} {{ ProductListFormSet }} <input type="submit" … -
How can I access multiple Querysets in a template in the same cycle?
I am transferring different similar Querysets to a template. Eg. qset01, qset02, ... qset10. The number of Querysets in known and can be transferred as well. How can I access these Querysets in a template in a cycle in the same iteration level. When I iterate through a single query, the code is: {% for i in qset01 %} {{i.field_01}} {% endfor %} What would it look like for many Querysets? This is what I need {% for more_complex_iteration %} {{qset01.field_01}}, {{qset02.field_01}}, ... {{qset09.field_01}} {% endfor %} Thank you -
multi-tenant architecture acessing tenant's external data source
I am building a Saas with django. Its job is to provide a dashboard for each tenant. The architecture is a multi-tenant with each tenant having its own schema in a postgresql database. My problem comes from the data processing on the backend. Each tenant needs to be able to pull data from an external source (most likely ERP system database), from there I have a python script that process this data and then stores it in the postgreSQL schema of the tenant. My biggest issue is the code to letting the tenant connect to its external database to pull data from outside. I have not found any way to do that from Django documentation. Would anyone has a hint on how to proceed or a resource I could consult. -

Django intersection of ManyToMany using Through model

Get values of ForeignKey related objects in django
There are two models in my django ORM: class Product(models.Model): product_id = models.IntegerField(default=0,unique=True) product_short_code = models.CharField(max_length=500, default=0,unique=True) class GRN(models.Model): owner = models.ForeignKey(Employee, on_delete=models.CASCADE, related_name='grn_owner') warehouse = models.ForeignKey(Warehouse, on_delete=models.CASCADE, related_name="grn_warehouse") reference_no = models.CharField(max_length=500, default=0) inward_date = models.DateField(default=datetime.now) product1 = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='grn_product1') product1_quantity = models.IntegerField(default=0) product1_price = models.IntegerField(default=0, blank=True, null=True) product2 = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='grn_product2', blank=True, null=True) product2_quantity = models.IntegerField(default=0, blank=True, null=True) product2_price = models.IntegerField(default=0, blank=True, null=True) product3 = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='grn_product3', blank=True, null=True) product3_quantity = models.IntegerField(default=0, blank=True, null=True) product3_price = models.IntegerField(default=0, blank=True, null=True) How can I get the short code of all the products stored in GRN model along with their total quantity?

Best practice for reverse access for foreign key in Django admin list_display
I have a django application which clients make some online orders and then we dispatch them by post courier. For orders and post parcels , I have defined two models which postparcel has order field as foreign key to Orders model. I put list_per_page = 250 . Now I have around 100,000 orders in my postgresql database. Everything is also indexed. In admin.py, I needed to access barcode for each postparcel when I view the order model in admin panel. So I made a function for the query. However, when I use Django admin toolbar, I can see 250 queries are made to catch all results from postparcel table. This is time consuming process. What is best practice for this. I tried using PostParcel__parcel_post_barcode and PostPacel.parce_post_barcode .. Both have compile error saying that this object is not found within this class. Please let me know how I can chain these two tables for one single query and make it faster in my admin panel. I found a code snippet here but seems old. I use django 3.1. I think there must be better way. https://djangosnippets.org/snippets/2887/ models.py class Orders(models.Model): order_id = models.CharField(max_length=255, null=True, unique=True, verbose_name=_("order id")) creation_time = models.DateTimeField(auto_now_add=True, verbose_name=_("creation time")) … -
Django - upload images with additional information
So let's say I have a blog website. And each blog consists of images. So, I want to sort the images depending on which blog they belong to. But when uploading, how do I automatically pass the blog id with the image? I have my model like this: class Blog(models.Model): name = models.CharField() blog = models.CharField() class Photo(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) file = models.FileField(upload_to=get_upload_path) My forms.py looks like: class PhotoForm(forms.ModelForm): class Meta: model = Photo fields = ('file', 'blog') You see in the fields there is 'blog'. How do I actually pass the blog id there? Currently, my html for upload page is like this: <div style="margin-bottom: 20px;"> <button type="button" class="btn btn-primary js-upload-photos"> <input id="fileupload" type="file" name="file" multiple style="display: none;" data-url="{% url 'blog' blog.id %}" data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'> </div> Actually this way of uploading images is taken from this great article by Vitor Freitas Now, I am wanting to pass the blog id to the template through views.py with context which I have done. But how do I save that and pass that with the images I upload? the views.py looks like: class BlogDetailView(View): def get(self, request,**kwargs): page = get_object_or_404(Page, pk=self.kwargs['pk']) context = {'page':page} return render(self.request, 'blog.html', context=context) … -

How can I stream big data to Google Cloud Storage?
I am working on a system for analyzing data of any size and format streamed by the users to my private cloud based on Google Cloud Storage. Do you have any ideas how can I allow them to stream big data? At the moment I use Django API and I do this in this way: def upload_blob(source_file_name, destination_blob_name): blob = bucket.blob(destination_blob_name) blob.upload_from_filename(source_file_name) print('File {} uploaded to {}.'.format( source_file_name, destination_blob_name)) It works correctly with small files however when I send for example large movie I get the error shown below. I am aware that this is not the optimal solution but I have no idea how can I solve this. As you can notice at the moment they send me requests with the blob format but with very large files it does not work. Do you have any ideas how can I solve my problem and send users data of any size to Google Cloud Storage?
