Remote Access to Django's Internet Server
I have a remote (virtual) Ubuntu development station, on which I installed Django, and on which I'm running "manage runserver". Now, I need to browse my project's URLs, and debug their view functions line by line. But I fail to remotely use the web browser on the remote development station (there was time that I succeeded doing so, but it was horribly slow). I therefore would like to enable the web browser on my own laptop to connect the web server of Django that's running on the remote development station. Is there a way to do so? -

Why my custom script processing data just fine on local development Django server but not on Digital Ocean App?
Does anyone know why when I upload a CSV file locally to the Django development server, my code does work as plan as in processing the CSV file and adding data to the database correctly, but when I try the same thing with the production server on Digital Ocean using App service - the CSV file just uploaded without having getting processed? I notice this because no new product is being added when uploading the CSV file to the production server on Digital Ocean. By the way, the local development server is also using S3 storage - so the same file got uploaded to Amazon S3 all the same - but the code processes the file in the development server but not on the production server - the development server is on my laptop. The production server is on Digital Ocean's App. I did something like this in the code: from django.core.files.storage import default_storage def upload_csvs(request): current_page_bread_crumb_title = 'upload csv' form = CsvsModelForm(request.POST or None, request.FILES or None) random_category = None if form.is_valid(): form.save() # reset form after save form = CsvsModelForm() # Only getting csv file that isn't activated or being used already. get_csv_data = Csvs.objects.filter(activated=False).order_by('-id').first() with default_storage.open(get_csv_data.file_name.name, mode='r') … -
How to query a dropdown in a Django ModelForm field based on current logged in user
I have a django model form were a user can submit their budget information. One of the fields in the form is a Category which is a foreign key from a Category Model. Unfortunately all users can see each other category's. How can I query the Category Field in the model form to only show logged in user. This is my Model.py from django.contrib.auth.models import User class Category(models.Model): user = models.ForeignKey(User,on_delete=models.SET_NULL,null=True,blank =True) TYPE = ( ('Income', 'Income'), ('Expense', 'Expense'),) category_feild = models.CharField(max_length = 100,unique = True) income_or_expense = models.CharField(default =" ",max_length=200, choices=TYPE) def __str__(self): return self.category_feild class Budget(models.Model): category = models.ForeignKey(Category,on_delete=models.CASCADE) date = models.DateTimeField(auto_now_add=False) budget_amt = models.FloatField(default= 0) comments = models.CharField(max_length = 140,default="") def __str__(self): return self.category.category_feild +' - ' + str(self.date.strftime('%b %Y')) This is my forms.py class budget_form(ModelForm): class Meta: model = Budget fields = ['category','date','budget_amt','comments' ] widgets = { 'category' : forms.Select(attrs={'class':'form-control'}), 'date' : forms.DateInput(attrs={'class':'form-control'}), 'budget_amt' : forms.NumberInput(attrs={'class':'form-control'}), 'comments' : forms.TextInput(attrs={'class':'form-control'}), } This is the view.py where I have attempted a query to filter for category of logged in users. def add_budget(request): b_form = budget_form if request.method == 'POST' and "budgetForminfo" in request.POST: budget_form.fields["category"].queryset= Category.objects.filter(user=request.user) b_form = budget_form(request.POST or None) if b_form.is_valid(): b_form.save() b_form = budget_form() return redirect('add_budget') … -
Connect Django to SQL database in Google Cloud's Compute Engine
My Django app has been working successfully using Google's App Engine standard environment. However I need to use Compute Engine for more power. I am testing a single VM instance running the app, however it has issues connecting to the POSTGRES database. The compute engine service account has all the same permissions as the app engine service account. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'HOST': '/cloudsql/myproject:us-central1:mypostgresname', 'NAME': 'mydatabasename', 'USER': 'myusername', 'PASSWORD': 'mypassword', } } -
How to replace empty values from api query to a number
I have a piece of code that pulls api data from an external website. The issue I am having is that during the pull it also saves the data to the database if it does not exist. Well some of the values from the json data I pull are empty and the database is expecting an integer when saving. How do I convert he json data empty strings to default 0? The Error ValueError at / Field 'he_displaced_threshold_ft' expected a number but got ''. services.py def get_runways(): params = { "apiToken": "SECRET", } api_base = "https://airportdb.io/api/v1/airport/KMIA" api_result = requests.get(api_base, params) api_response = api_result.json() for runway in api_response["runways"]: runway_data, created = Runway.objects.update_or_create( airport_ident=Airport.objects.get(ident=runway["airport_ident"]), length_ft=runway["length_ft"], width_ft=runway["width_ft"], surface=runway["surface"], lighted=runway["lighted"], closed=runway["closed"], le_ident=runway["le_ident"], le_latitude_deg=runway["le_latitude_deg"], le_longitude_deg=runway["le_longitude_deg"], le_elevation_ft=runway["le_elevation_ft"], le_heading_degT=runway["le_heading_degT"], le_displaced_threshold_ft=runway["le_displaced_threshold_ft"], he_ident=runway["he_ident"], he_latitude_deg=runway["he_latitude_deg"], he_longitude_deg=runway["he_longitude_deg"], he_elevation_ft=runway["he_elevation_ft"], he_heading_degT=runway["he_heading_degT"], he_displaced_threshold_ft=runway["he_displaced_threshold_ft"], ) runway_data.save() return runway models.py class Runway(models.Model): airport_ident = models.ForeignKey(Airport, on_delete=models.CASCADE) length_ft = models.IntegerField(default=None, blank=True, null=True) width_ft = models.IntegerField(default=None, blank=True, null=True) surface = models.CharField(max_length=50, blank=True, null=True) lighted = models.IntegerField(default=None, blank=True, null=True) closed = models.PositiveBigIntegerField(default=None, blank=True, null=True) le_ident = models.CharField(max_length=5, blank=True, null=True) le_latitude_deg = models.FloatField(default=None, blank=True, null=True) le_longitude_deg = models.FloatField(default=None, blank=True, null=True) le_elevation_ft = models.IntegerField(default=None, blank=True, null=True) le_heading_degT = models.FloatField(default=None, blank=True, null=True) le_displaced_threshold_ft = models.IntegerField(blank=True, null=True) he_ident = models.CharField(max_length=5, blank=True, null=True) he_latitude_deg … -
Get data belongs to a field of model in select_related to a list and create a dataframe
I'm trying to query two related tables and create a pandas dataframe then use it for rule mining. The dataframe should look like this, order products ---------------- 1 ['product1', 'product2'] 2 ['product1', 'product3', 'product10'] ... My models, class Order(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) product = models.ManyToManyField(Product, through='OrderedProduct', related_name='orders') class OrderedProduct(models.Model): order = models.ForeignKey(Order, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.DO_NOTHING) quantity = models.IntegerField(default=1) class Product(models.Model): name = models.CharField(max_length=255) price = models.DecimalField(max_digits=10, decimal_places=2) I've done the dataframe creating part as follows in views, and it works but needs preprocessing to get end result and feels it's inefficient for a larger dataset. orders = OrderedProduct.objects.all().values('order__id', 'product__name') df = pd.DataFrame.from_records(orders) df = df.groupby(['order__id'])['product__name'].apply(list).to_list() So, my question is 'Is there a more direct and efficient approach to do this?'. Any advice is highly appreciated.
