How to convert raw sql to Django ORM?
I have been given sql query and I have to convert it to Django ORM and output should be the same. sql_query = "SELECT a.ID, a.post_title, a.post_name, a.post_date, d.meta_value, e.meta_value FROM wp_8_posts a, wp_8_term_relationships b, wp_8_term_relationships c, wp_8_postmeta d, wp_8_postmeta e WHERE a.post_type = :post_type AND a.post_status = 'publish' AND a.ID = b.object_id AND b.term_taxonomy_id = 1 AND a.ID = c.object_id AND c.term_taxonomy_id = :post_tag AND a.ID = d.post_id AND d.meta_key = 'upurl' AND a.ID = e.post_id AND e.meta_key = 'target' ORDER BY a.post_date DESC;" models.py class Wp_8Post(models.Model): ID = models.IntegerField(primary_key=True,null=False,default=None) post_author = models.IntegerField(null=False,default=0) post_date = models.DateTimeField(null=False) post_title = models.TextField(null=False,default=None) post_status = models.CharField(max_length=20,null=False,default='publish') post_name = models.CharField(max_length=200,null=False,blank=True) post_modified = models.DateTimeField(null=False) guid = models.CharField(max_length=255,null=False,blank=True) post_type = models.CharField(max_length=20,null=False,default='post') class Meta: app_label = 'cms' db_table = 'wp_8_posts' class Wp_8Postmeta(models.Model): meta_id = models.IntegerField(primary_key=True,null=False,default=None) post_id = models.ForeignKey(Wp_8Post,on_delete=models.CASCADE) meta_key = models.CharField(max_length=255,null=True,default=None) meta_value = models.TextField(null=True,default=None) class Meta: app_label = 'cms' db_table = 'wp_8_postmeta' class Wp_8Termrelationships(models.Model): object_id = models.ForeignKey(Wp_8Post,on_delete=models.CASCADE) term_taxonomy_id = models.IntegerField() term_order = models.IntegerField(null=False,default=0) class Meta: app_label = 'cms' db_table = 'wp_8_term_relationships' UniqueConstraint( name = 'term_relationship', fields = ['object_id','term_taxonomy_id'] ) First I thought to minimize the sql query by using INNER JOIN so I tried this but I got confused why same table is being used two times … -
Django forms how to initialze only not required field instead of passing all required fields
class Student(models.Model): name = models.CharField(null=True, blank=True) fieldA = models.TextField(null=True, blank=True) fieldB = models.TextField(null=True, blank=True) fieldC = models.TextField(null=True, blank=True) fieldD = models.TextField(null=True, blank=True) class Meta: model = Student fields = '__all__' Based on the above example all fields are taken in UpdateView or CreateView. If i need to take only required field i can change Meta to class Meta: model = Student fields = ['name','fieldA',fieldB','fieldC'] So my question is how can add only fields that should not pass in the Meta.From above example 'fieldD' is not passed. Is there is any way to say 'fieldD' is not required instead on passing all required fields in Meta.So that the code can be reduced. Above one is a small example. Consider I have 200 fields and only 1 field that I didnot want to pass so instead of passing 199 required fields in Meta is there is anyway to tell only the 1 field should not pass -

How to use Django without database
I'm creating an app with a React frontend. The purpose of the backend is to call a public API, process the data retrieved from the public API, and then with a REST API transfer the post-processed data to the view (React frontend). I would like to use python in the backend, so I started with using Django. However, it seems Django is very much focused on Models and Databases. I do not need a database for this app. Is Django the right tool to use for this? -

Django: Nested Sum() annotations across three Model Relations
I am using Django to sort out a storefront environment to handle orders and am struggling on one of the annotations I am attempting to write. The salient data models are as such class Order(ClusterableModel): "various model fields about the status, owner, etc of the order" class OrderLine(Model): order = ParentalKey("Order") product = ForeignKey("Product") quantity = PositiveIntegerField(default=1) base_price = DecimalField(max_digits=10, decimal_places=2) class OrderLineOptionValue(Model): order_line = ForeignKey("OrderLine", related_name="option_values") option = ForeignKey("ProductOption") value = TextField(blank=True, null=True) price_adjustment = DecimalField(max_digits=10, decimal_places=2, default=0) The OrderLine represents one or more of a specific product being bought at a specific base price and quantity. This base price has been copied from the product model in order to preserve the price of the product at the time the order was created. The Order therefore is just a collection of multiple OrderLines The complexity comes in the OrderLineOptionValue model which represents a modification to the base price based on the choices made by the user, and each order line may have multiple adjustments if the product has multiple options. Color, size, weight, etc may each have variable price impacts. When querying the OrderLine model I have been able to successfully annotate each result with that line's appropriate line … -

Django Form is not submitting, even though it seems to be working
My form is still not submitting. I am stressed out now, I am rebuilding my app from the ground up because a form wasn't working (in total I have three, the other two did work), and it still isn't working.

how to write DRF serializers for the desired output?
need to get the following output using the below given model structure { "User": [ { "id": 1, "name": "XYZ", "Task": [ { "id": "1", "task_name": "task 1" }, { "id": "2", "task_name": "task 2" } ] }, { "id": 2, "name": "ABC", "Task": [ { "id": "1", "task_name": "task 1" } ] } ] } This is how the model is designed and I want the above output without dealing with extra database query for each record (n+1). Can this be achieved using select_related or prefetch related or something else? class User(models.Model): name = models.Charfield() class Task(models.Model) task_name = models.Charfield() class UserTask(models.Model): user = models.Foreignkey(User, related_name = 'user') task = models.Foreignkey(Task, related_name = 'tasks') -
How to get dynamically created glb from django backend to display in three.js
I have an application that takes user input and creates a 3D model from that input in a python script. I now want to visualize this 3D object using three.js. My problem is that I cannot seem to get the data from the backend to the three.js GLTFLoader in the correct format. The glb data is generated with trimesh. I am certain the 3D model is created correctly because I can output it to a file and open it in Blender. The loading of static resources in the glb format through three.js also works. But since the content is dynamically created, I do not want to save it on the server-side unless the user decides to keep it. My current approach is to try and include the 3D model in the content of a template view. The three.js documentation says, glb data can be parsed from a js BufferArray. But it seems the data gets read as a binary string in js: "b'......'" The views.py: class PreviewView(TemplateView): template_name = 'editor/preview.html' context_object_name = 'preview_generated' def get_preview(self, request): from editor.tools.gltf import GLTFConverter raw_lines = json.loads(request.POST.get('vertex_sets')) if type(raw_lines[0]) is list: lines = [np.pad(np.array(line).reshape((-1,2)),[(0,0),(0,1)], mode='constant') for line in raw_lines] else: lines = [np.pad(np.array(raw_lines).reshape((-1,2)),[(0,0),(0,1)], mode='constant')] … -
