Djongo FAILED SQL: INSERT INTO \<TABLENAME>
I'm new to the Django Framework and I am using Djongo connector to connect to the MongoDB backend database. When I try to insert a large dictionary i run into a error and i am unable to insert the record in MongoDB. I will be adding a condensed version of the code here. My model.py is given below, i am using the binary field to store the dictionary. from djongo import models as MongoModel class QuickInsights(MongoModel.Model): ChartAttributesData = MongoModel.BinaryField(blank=True) This is what my view.py looks like. def Save(request): try: InsightDocument = QuickInsights.objects.create( ChartAttributesData=request.data.get("ChartAttributesData") MongoId = request.data.get("MongoID") UserID = request.data.get("UserID") ) InsightDocument.save() return Response(status.HTTP_200_OK) except ValueError as e: return Response(e.args[0], status.HTTP_400_BAD_REQUEST) My dictionary is roughly around 30K lines after beautifying/formatting. I can comfortably insert large data to MongoDB via it's shell, but i have an issue while doing the same from Django with the Djongo connector. Is it because of the Model Binary field or the Djongo connector cannot process it? -

NoReverseMatch error argument not found, Django newbie

I'm working on building my first from scratch app, a tinder clone, on Django.

Django - Posting 2d list of multiple files results to single list
I have dynamic fields: <input type='text' name='names[]'> and <input type='file' name='images[]' multiple> which i will be posting to a view and be processed in batch by zipping the fields. The problem is when I post it, the images[] will be received as single list instead of 2d list. single list: images = [<file 1>, <file 2>, <file 3>, <file 4>] where it should be 2d list: images = [[<file 1>, <file 2>], [<file 3>, <file 4>]]. I need the images to be in 2d list since I will be using them on a zip. is there anyway I can do this without having different names for each <input type='file' name='images[]' multiple> row? template: <form action="__post_url_here__" method="POST" enctype="multipart/form-data"> <div> <input type="text" name="names[]" /> # has value of name 1 <input type="file" name="images[]" multiple /> # has value of [<file 1>, <file 2>] </div> <div> <input type="text" name="names[]" /> # has value of name 2 <input type="file" name="images[]" multiple /> # has value of [<file 3>, <file 4>] </div> ... ... </form> view: form_data = request.POST file_data = request.FILES names = form_data.getlist("names[]") images = form_data.getlist("images[]") print(names) # this results to ["name 1", "name 2"] print(images) # this results to [<file 1>, <file … -

Elasticsearch DSL Filter
I am having a problem with the elastic-search filter. I am trying to search for a text using elastic-search DSL filter, but I am facing issue with sorting. Search text: hello world Other string in the document: Hello there, hello world, hello everyone, hi hello, etc... Elasticsearch-dsl query is: MyDocument.search().filter(Q("match", title="hello world") | Q("match", original_title="hello world")).execute() Elasticsearch query is like this: { 'bool': { 'filter': [{ 'bool': { 'should': [{ 'match': { 'title': 'hello world' } }, { 'match': { 'original_title': 'hello world' } }] } }] } } The output is like hello everyone, hi hello, hello world, etc.. but I want hello world first.

how to get count of rating in django rest framework
I have a model like that class UserRating(models.Model): product = models.OneToOneField(Product, on_delete=models.CASCADE, null=True) rate = models.PositiveSmallIntegerField() status = models.BooleanField(default=False) I rate this in a range of 1 to 4 where 4 is excellent, 3 is very good, 2 is good, 1 is bad and I should get the count of rating according to the number given by user. I am using SerializerMethodField like that is def get_excellent(self, obj): return models.UserRating.objects.filter(rate=4, status=True).count() def get_very_good(self, obj): return models.UserRating.objects.filter(rate=3, status=True).count() def get_good(self, obj): return models.UserRating.objects.filter(rate=2, status=True).count() def get_bad(self, obj): return models.UserRating.objects.filter(rate=1, status=True).count() but it is bad idea to do this because it goes to the db the four times. I am looking for better way of doing this. Is there any help please! Thanks in advance! -
How to check BASE_DIR in django?
I was running into a lot of file not found for webpack in my static folder, and I later realized that for some reason this particular project (which I'm using docker with) keeps trying to check another project folder's static folder for the files I would want. I'm not sure where this could've gone wrong other than the base_dir, but I never changed that setting. There was a while I was going between the projects and trying to run each one (the other project is basically the same thing but not on docker), was that possibly what's confusing the program? How can I solve it? -

Python Weasyprint causing High CPU usage, How do I queue rendering?
Please bear with me as i put these into words, I am running Weasyprint on Python Django Framework, I have have 15 page html to render to PDF.

My question is, Is there something I can use to queue users request for rendering? Instead of processing render requests at the same time, make them wait in a queue? -

Django Rest Framework: filtering on relationships using hyperlink URIs
I'm using Django Rest Framework to create a simple API. I have two models with a foreign key relationship: class Article(models.Model): publisher = models.ForeignKey('Publisher', ...) class Publisher(models.Model): name = ... I am serializing them using hyperlink identifiers: { "url": "http://localhost:8000/api/1/article/1", "publisher": { "url": "http://localhost:8000/api/1/publisher/1", "name": "Publisher One" }, ... } I'd like to filter all articles against the publisher of a specific article, ideally something of this form: http://localhost:8000/api/1/article?publisher=http://localhost:8000/api/1/publisher/1 I tried creating a custom FilterClass, however url isn't an actual field on the model, so I'm uncertain how to reference it. If I extract the id from the URL and pass that through it works as expected, but I'd rather the client not need to know how to parse a hyperlinked identifier for the "real" identifier. I can add the id to the serializer as well but if that's the solution what even is the point of the HyperlinkedModelSerializer? -
Need 4 dropdowns which depends on user selection,according to each user selection respective dropdown will be shown
I want to create something like first user selects the bank and than user selects the district and than user selects the branch and than I display the ifsc code .I've made an example where first user selects the bank and than the district .How should I do it after district branch and than IFSC .So basically 4 dropdowns <select id="Bank_Detail" onchange="fun(this.value)" > <option value=''>select</option> <option value="sbi">SBI</option> <option value="axis">AXIS</option> </select><br/><br/> <select id="sbi_district"> <option value="north">North</option> <option value="south">South</option> </select> <select id="axis_district"> <option value="west">West</option> <option value="east">East</option> </select> <body onLoad="fun('')"> <select id="Bank_Detail" onchange="fun(this.value)" > <option value=''>select</option> <option value="sbi">State Bank Of India</option> <option value="axis">Axis</option> </select><br/><br/> <select id="sbi_district"> <option value="west">West</option> <option value="east">East</option> </select> <select id="axis_district"> <option value="north">North</option> <option value="south">South</option> </select> </body> <script> function fun(val) { if(val=="sbi") { $('#axis_district').hide(); $('#sbi_district').show(); } else if(val=="axis") { $('#sbi_district').hide(); $('#axis_district').show(); } else if(val=='') { $('#sbi_district').hide(); $('#axis_district').hide(); } } </script>
