How to create a new column for Django Model field and add it to the existed function?

Saving a Pandas DataFrame column to a ForeignKey Django model field
So let me explain briefly first. I have some DataFrames that I want to save as a Django model. I use the Pandas to_sql function for this, which has worked brilliantly for me untill now. So for example I have this Order model: class Order(models.Model): id = models.BigIntegerField(primary_key=True) item_id = models.CharField(max_length=255, null=True, blank=True) ean = models.BigIntegerField(null=True, blank=True) date = models.DateTimeField(null=True, blank=True) My DataFrame has exactly the same columns that match the Django model fields. So I run this to save it to the Django model: # Save to SQL user = settings.DATABASES['default']['USER'] password = settings.DATABASES['default']['PASSWORD'] database_name = settings.DATABASES['default']['NAME'] database_url = 'postgresql://{user}:{password}@localhost:5432/{database_name}'.format( user=user, password=password, database_name=database_name, ) engine = create_engine(database_url, echo=False) # Use replace for tables that already exist and set appropiate types with sqlalchemy | https://docs.sqlalchemy.org/en/13/core/type_basics.html#sql-standard-and-multiple-vendor-types df_final.to_sql('orders_order', dtype={'id': sqlalchemy.types.BIGINT(), 'item_id': sqlalchemy.types.VARCHAR(), 'ean': sqlalchemy.types.BIGINT(), 'date': sqlalchemy.DateTime(), }, con=engine, if_exists='replace', index=False) All good, works perfect. The DataFrame gets saved and I can view all seperate entries in the Django Admin. However I would like to save a DataFrame to a Django model which has a ForeignKey relationship with the Orders model. So in my point of view I should just populate the fields with the appropiate data. So for this model with a … -
How to correctly display data stored in an external model without refreshing the page?
I am trying to display a User's name on top of a box where they enter their Employee # in a form, without having to refresh the page. For example, they enter their # and then after they click/tab onto the next field, it renders their name on top, which comes from the database, so the user knows they've entered the correct info. This name is stored in a separate model, so I try to retrieve it using the "id/number". I am not too familiar with AJAX but after reading a few similar questions it seems like an AJAX request would be the most appropriate way to achieve this. I tried to make a function get_employee_name that returns the name of the person based on the way I saw another ajax request worked, but I'm not sure how to implement this so it displays after the # is entered. models.py class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): employee_number = models.ForeignKey(Salesman, on_delete=models.SET_NULL, help_text="Employee #", null=True, blank=False) work_area = models.ForeignKey(WorkArea, on_delete=models.SET_NULL, null=True, blank=False) station_number = models.ForeignKey(StationNumber, on_delete=models.SET_NULL, null=True, blank=True) def __str__(self): return self.employee_number This is the model where the name is stored alldata/models.py class Salesman(models.Model): slsmn_name = models.CharField(max_length=25) id = models.IntegerField(db_column='number', primary_key=True) I was reading … -

I am creating an app when a user can search for recipes by inputing some ingredients in search-field. I would like to do that when search-field is empty or string is empty a user get error.message 'Please put input.' But after i have implemented message.error into views and template it only returns the same page without this informaton 'Please put input.'. Do you know what i made wrong here?

send my response for 2 groups via self.channel_layer.group_send()
I'm using django channels 2 , for making a one to one private chat. And after spending a LOT OF TIME i'm just out of any other solution for my problem I have two html files: inbox.html shows list of all user history that i had chat with them and it is ordered by last updated time(last chat with each user) and if you click on one of them then you see the other file showing the chat room. I want to use my ChatConsumer for two urls. I send my_response in websocket_receive function and then receive it in socket.onmessage in template THE PROBLEM IS I can't do it for both urls. I want to send it into my inbox too because I want to reOrder the chat user lists every time I send a message.so I made a group for inbox in my consumers as I did for my chat_room in websocket_connect function: inbox_room = f"inbox_{me.id}" self.inbox_room=inbox_room await self.channel_layer.group_add( inbox_room, self.channel_name ) and then I tried two ways: 1- just use channel_layer.group_send for both of them: await self.channel_layer.group_send( self.chat_room, self.inbox_room, { "type": "chat_message", "text": json.dumps(my_response) } ) and then using : async def chat_message(self,event): await self.send({ "type": "websocket.send", "text":event['text'] … -
