Really weird behaviour when running a function, coding it in shell works, importing the function doesn't
I have no idea what's happening here. ​ I have a class that looks something like, ​ class Scrape: def __init__(self, session, headers, proxies): self.session = session self.headers = headers self.proxies = proxies self.response = None def post(self, url): self.response = self.session.post(url, headers=self.headers, proxies=self.proxies, verify=False) def get(self, url): self.response = self.session.get(url, headers=self.headers, proxies=self.proxies, verify=False) Then I have this function in another file, import requests from .config import * from .scraper import Scrape from .serializer import * import urllib3 urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) def run(): scrape = Scrape(requests.session(), headers, PROXIES) scrape.post(url) save = [] for obj in scrape.parse_response(): ....... Now this works perfectly in my development environment, but when I deploy it, I get this. urllib3.connection.HTTPConnection object at 0x7f69ccf34710>: Failed to establish a new connection: [Errno 110] Connection timed out',))) Now at first I thought my server had whitelists and stuff, BUT if I do this, In [10]: from bots.roku.config import * In [11]: import requests In [12]: r = requests.session().post(url, headers, PROXIES) In [13]: r Out[13]: <Response [200]> IT WORKS?

Best way to render HTML to PDF in Django site
I have pretty complicated css in my HTML and I tried to render it to PDF using xhtml2pdf but it does not support my css. So I tried to use reportLab but then it might take times because I have to do the design all over again (also I'm not sure how can I insert my fetch data from db into the pdf using it). So in my case what is the best way to render HTML to PDF in Django ? -
Django foreign key form
I have two models Order and a date model. Order model has a foreign key attribute of date model. I have made a form in which I can update the date fields of order, but when I click submit it creates a new date object in date model not in the order date field. I want my form to save values in the date field in order. models.py class Order(models.Model): date = models.ForeignKey('date', null=True, on_delete=models.CASCADE) user = models.ForeignKey(User, null=True, on_delete=models.CASCADE) quote_choices = ( ('Movie', 'Movie'), ('Inspiration', 'Inspiration'), ('Language', 'Language'), ) quote = models.CharField(max_length =100, choices = quote_choices) box_choices = (('Colors', 'Colors'), ('Crossover', 'Crossover'), ) box = models.CharField(max_length = 100, choices = box_choices) pill_choice = models.CharField(max_length=30) shipping_tracking = models.CharField(max_length=30) memo = models.CharField(max_length=100) status_choices = (('Received', 'Received'), ('Scheduled', 'Scheduled'), ('Processing/Manufacturing', 'Processing/Manufacturing'), ('In Progress','In Progress'), ) status = models.CharField(max_length = 100, choices = status_choices, default="In Progress") def __str__(self): return f"{self.user_id}-{self.pk}" class Date(models.Model): date_added = models.DateField(max_length=100) scheduled_date = models.DateField(max_length=100) service_period = models.DateField(max_length=100) modified_date = models.DateField(max_length=100) finish_date = models.DateField(max_length=100) view.py def dateDetailView(request, pk): order = Order.objects.get(pk=pk) date_instance = order.date form = DateForm(request.POST, request.FILES, instance=date_instance) if request.method == 'POST': if form.is_valid(): order = form.save(commit = False) order.date = date_instance order.save() context = { 'order':order,'form':form } else: … -
Preventing users writing foul language in the comment section
I don't want users to be able publish offensive comments on my posts. I know a way of censoring out s***, f***, c*** etc. But if you apply a blanket ban to offensive words then you may unintentionally end up banning a word such as Scunthorpe (a place in the UK) because it contains an offensive substring. In forms.py I want to set the comment active property to false if the comment potentially contains an offensive word. Therefore I could manually check any potentially controversial posts. models.py class Comment(models.Model): #The foreign key is linked to the ID field in the Post model #id = models.IntegerField(primary_key=True, blank=False) post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments') nameid = models.ForeignKey(User,on_delete=models.CASCADE,related_name='commentsid') name = models.CharField(max_length=80) email = models.EmailField() body = models.TextField() created_on= models.DateTimeField(default = timezone.now()) active = models.BooleanField(default=True) forms.py I have tried setting active to false in at least 4 different ways but have so far had no luck. Does anyone have any suggestions? def clean_body(self): body = self.cleaned_data.get("body") if "f***" in body or "s***" in body : self.data['active'] = False self.fields['active'].initial = False self.cleaned_data.get("active")=False form.fields['active'].initial = False return body -
Django Does Not Detect Tests Ran 0 tests in 0.000s

Django Crispy forms helper throwing Failed lookup for key [helper] error
I cannot get crispy form helper to work with forms or formsets. If I simply user the {% crispy form %} or {% crispy formset %} tags, depending on implementation, the forms appear and function normally. Of course, this is a problem when I'm trying to use layouts with crispy helpers. When I user {% crispy form form.helper %} or {% crispy formset helper %}, my app throws errors that: Failed lookup for key [%s] in %r / Failed lookup for key [helper] error This is very strange as it only applies to helpers and I have tried passing in helpers, different attributes, and queryset data.

jQuery DataTables is not a function error randomly occurring in Safari
I've been trying to use DataTables and other jQuery JS libraries in a Django-based web application. I call the .DataTable function in the document ready function. I have had no issues with Firefox and Chrome, but in Safari, some of the times I load the page, I get a .dataTable is not a function error, and the table does not render as a DataTables formatted table. However, other times I load the page, it seems to be working fine. Additionally, it seems that when there are issues with DataTables loading, other libraries also seem to have errors loading as well. I have ensured that jQuery is being imported only once, and prior to DataTables in the code. Even when the errors occur, it seems that DataTables is still being loaded by the browser. As I mentioned, the error only seems to happen in Safari and only seems to occur part of the time. Any insights? -
Set Model Field as Required in Django
Django doesn't enforce NOT NULL at the model/database level. device_serial is neither supposed to have blank '' nor null class Device(models.Model): device_serial = models.CharField(max_length=36, unique=True, null=False, blank=False) ....etc The statement below works totally fine! I expect it to fail because device_serial is required. It shouldn't accept empty string '' Device.objects.create(device_serial='') How can I make a field required at the model / database level? What could I possibly be doing wrong here? I don't see where did I go wrong. I tried ''.strp() to convert empty string to None but it didn't work -
Custom model permission in django-admin to edit a particular field
Normally, after migrating the models located in models.py, in django-admin you get a set of default permissions for your models. For example: models.py class Appointment(models.Model): time = models.TimeField(auto_now_add=False, auto_now=False, null=True, blank=True) notes = models.TextField(blank=True, null=True) In django-admin I can assign these permissions to a group: appname|appointment|Can add appointment appname|appointment|Can change appointment appname|appointment|Can delete appointment appname|appointment|Can view appointment However, I want to add a new permission to this list that will be able to allow a staff user to change the notes field only, such as: appname|appointment|Can change appointment notes I know I can add it like this: class Meta: permissions = [ ("change_notes", "Can change appointment notes"), ] However, the lines above will only add the permission to the list, and after assigning it to a group nothing happens (the notes field cannot be changed). How can I solve this? Is there any Django extension that can help me add a custom model permission in to edit a particular field? -

Using DJANGO_SETTINGS_MODULE in a script in subfolder

What i mean by that is for example: When my client want to collect his order from shop, it will outputs string but when he want to send it, it will shows up his address. class Customers(models.Model): textcustomer_id = models.AutoField(primary_key=True, null=False) customer_name = models.CharField(max_length=100, null=True) phone_number = models.CharField(max_length=9, null=True) customer_adrress = models.CharField(max_length=10, null=True) def __str__(self): return f'{self.customer_id}' class Meta: verbose_name_plural = "Customers" class Orders(models.Model): CUSTOMER_ADDRESS_CHOICE = ( ('ADRES KLIENTA', 'ADRES KLIENTA'), ('ODBIÓR OSOBISTY', 'ODBIÓR OSOBISTY'), ) STATUS_CHOICES = ( ('W TRAKCIE', 'W TRAKCIE'), ('ZAKOŃCZONE', 'ZAKOŃCZONE'), ) PAYMENT_STATUS_CHOICES = ( ('NIEZAPŁACONE', 'NIEZAPŁACONE'), ('ZAPŁACONE', 'ZAPŁACONE'), ) order_id = models.AutoField(primary_key=True, null=False) order_date = models.DateField(auto_now_add=True, null=True) customer_id = models.ForeignKey(Customers, on_delete=models.SET_NULL, null=True) customer_address = models.CharField(max_length=20, choices=CUSTOMER_ADDRESS_CHOICE, null=True) cost = MoneyField( decimal_places=2, default=0, default_currency='PLN', max_digits=11, ) status = models.CharField(max_length=20, choices=STATUS_CHOICES, null=True) payment_status = models.CharField(max_length=20, choices=PAYMENT_STATUS_CHOICES, null=True) def __str__(self): return f'{self.order_id}' class Meta: verbose_name_plural = "Orders" -
