Obtaing Max Allowed Value of PositiveSmallIntegerField Django Field
I have the following PositiveSmallIntegerField attached to a Model as follows: class Proficiency(models.Model): class Meta: verbose_name = 'Proficiency' verbose_name_plural = 'Proficiencies' ... ... rating = models.PositiveSmallIntegerField(default=0, validators=[MinValueValidator(0), MaxValueValidator(10)]) I have to do some complex calculations (*which can't be done within the ORM as far as I can see) on an endpoint which returns an average value: The calculation turns out to be: candidate['average'] = (candidate['total'] / count) * maximum_value_of_proficiency_rating_field i.e., maximum_value_of_rating_field is 10. Inspection of this field, and some digging into object attributes etc has lead me to find 10 dynamically as the following: proficiency._meta.get_field('rating')._validators[1].limit_value However, I was wondering if there was a simpler way to find the maximum value of a PositiveSmallIntegerField... i.e., either whatever value passed into the MaxValueValidator(10) i.e., "10" or if there is no MaxValueValidator, then 32767. I was thinking something like maybe a method would return this safely, or maybe an attribute on the field, i.e.,: proficiency.rating.get_maximum_value() or proficiency.rating.max_value Does anyone know if there is such a class method or attribute on the field to do this? -
Bootstrap dual list box POST Selected
I'm trying to post selected data from Bootstrap dual list (https://www.virtuosoft.eu/code/bootstrap-duallistbox/) do django. I'm using example code from https://codepen.io/jaredbell/pen/OejgMe. Problem occurs when i try to send selected items to view in django - i'm always getting one selected item instead of multiple selected items. Given example from https://codepen.io/jaredbell/pen/OejgMe showing selected items with js alert script works well but when I try to get selected items with django there is always one selected item instead of list of selected items. If you have any ideas i would be very appreciate. Regards django ( views.py ): if request.method=='POST': q=request.POST.get('duallistbox_demo1[]','') return HttpResponse(q) # always one item html: same code as https://codepen.io/jaredbell/pen/OejgMe -

save an instance of object in two models simultaneously
I am trying to create a route that will track all the history of a product. I have created a model for the product and a similar model for producthistory. Now, whenever I am creating an object I want it to be saved in the product table as well as the producthistory table. The only difference in both the tables is the id field. The producttable contains the id of the product & the producthistorytable has an id field of the historytable as well as the id of the product. I want to filter with the id of the product for further usage of the data. How can I insert the product object in the producthistory table along with the id of the product that was created at that point in time? Here is the models: class Product(Base): __tablename__ = "product" id = Column(Integer, primary_key=True, index=True) product_url= Column(String) current_price= Column(Integer) updated_at= Column(String) created_at= Column(String) target_price= Column(Integer) product_name= Column(String) class ProductHistory(Base): __tablename__ = "producthistory" id = Column(Integer, primary_key=True, index=True) product_id = Column(Integer) product_url= Column(String) current_price= Column(Integer) updated_at= Column(String) created_at= Column(String) target_price= Column(Integer) product_name= Column(String) here is the logic for creating product: @app.post('/createproducts/') def createproducts(request: Product, db:Session = Depends(get_db)): product = models.Product( … -

Django Application data not persisting for deployment
Currently developing a Django application to be deployed onto a digital ocean droplet. On this droplet there is 4 docker containers for: PostgreSQL, PGADMIN4, Django App, Certbot. In Django Admin (localhost), I have added some values to my database and they will be displayed throughout the web application. However, when I deploy my Django Application to the digital ocean droplet, this data is nowhere to be seen. I read that I can make a sql dump file of my local database and get the values on my droplet that way. But id rather another way if possible. I have done this process before but I was using a postgis database that came with a prebuilt database, whereas now I have to create a database again on my postgresql container (locally and on droplet).

Highcharts Sankey Colors not working in django

For example, the colors in the server do not work yet on the static HTML they render perfectly. Kindly assist. Thanks -
Django REST framework HyperlinkedIdentityField format kwarg not working
I have just started looking into Django REST Framework and am following the tutorial in the official documentation. In this tutorial, we use HyperLinkedIdentityField for highlight attribute. We set the format kwarg to html. The tutorial states: Notice that we've also added a new 'highlight' field. This field is of the same type as the url field, except that it points to the 'snippet-highlight' url pattern, instead of the 'snippet-detail' url pattern. Because we've included format suffixed URLs such as '.json', we also need to indicate on the highlight field that any format suffixed hyperlinks it returns should use the '.html' suffix. The problem is that when I visit the snippet-list using the url http://127.0.0.1:8000/snippets/?format=json I get the highlight url as http://127.0.0.1:8000/snippets/1/highlight/?format=json while I expected it to be http://127.0.0.1:8000/snippets/1/highlight/?format=html because no matter what format we request the snippet-list url, the highlight link will always have HTML format. My code looks like this: highlight = serializers.HyperlinkedIdentityField(view_name='snippet-highlight', format='html') class Meta: model = Snippet fields = ['url', 'id', 'highlight', 'owner', 'title', 'code', 'linenos', 'language', 'style'] Any help will be highly appreciated Thanks, -

serializing foreing key variable in update method
I'm trying to override the update method of a serializer. This serializer have a field 'gear' which is a foreing key of the Trawl table. But when I try to save the updated instance in update method, I get the error: ValueError: Cannot assign "2": "Haul.gear" must be a "Trawl" instance This is the serializer: class HaulTrawlSerializer(serializers.ModelSerializer): gear = serializers.IntegerField() class Meta: model = Haul fields = ['id', 'haul', 'gear', 'valid', ] def update(self, instance, validated_data): if validated_data: for attr, value in validated_data.items(): print(attr, value) setattr(instance, attr, value) instance.save() return instance So I try to convert Haul.gear to a Trawl instance changing the update method: def update(self, instance, validated_data): instance.gear = Trawl.objects.get(pk=validated_data.pop('gear')) if validated_data: for attr, value in validated_data.items(): print(attr, value) setattr(instance, attr, value) instance.save() return instance And then, the error TypeError: int() argument must be a string, a bytes-like object or a number, not 'Trawl' is thrown and I don't understand it.
