Django web page times out with xxx.objects.all()[:nnn] when nnn > 200
I'm familiar with Python 3 and am learning Django to try and create a web front end which uses information from a MySQL database. I'm using a development server on local machine (http://127.0.0.1:8000/) Package Version ---------------------- ------- Django 2.1.7 mysql-connector-python 8.0.15 I've defined the Customers class in 'models.py' and set up the customers app in Django. The app works perfectly (i.e.: I see output and the web page returned looks as expected. I use the following in the 'views.py' file: # Create your views here. def index(request): customers = Customers.objects.all()[:200] context = { 'title': 'Latest Customers', 'customers': customers } return render(request, 'customers/index.html', context) I get: [26/Mar/2019 21:30:11] "GET / HTTP/1.1" 200 38377 When I change the limit to anything higher than 200, e.g.: customers = Customers.objects.all()[:201] the web page fails to render (times out). Is there a hard limit set somewhere? What would be the best way to find out why the web page is not rendering? -

Django ORM relatedmanager adding defaults to filters
Unexpected filters in SQL for related manager. Filters appear to be on fields where I've set a default value in their declaration in the model. We've upgraded from Python 2.7 / Django 1.8 to Python 3.6 / Django 2.1 and have started seeing this unexpected behaviour in our ORM queries.

Empty value for string in model function
First project newbie here - In this model I am trying to create a field that combines first and last names of two people depending if they are the same or not. If the last name is the same, I want it to display as "first_name1 & first_name2 last_name1". It works except that when last_name1 is empty, which will be the case a lot of the time, it displays something like "John & Jane None". I had to specify last_name1 as a string or else I got an error: must be str, not NoneType. How do I do this properly? Also what do I call this type of function in a model...is it a manager?

How to override django-allauth signup form when custom user contains FK relation to another model?
I have an abstract user that contains a relation to a Company model by a FK (so each user belongs to a Company) and some additional fields. I have created a CustomSignupForm(SignupForm) that inherits django-allauth SignupForm and takes additional fields like first_name, last_name but I need to expand it so that every time a user does signup I create a Company and then assign the user to (set the FK). This is my forms.py that creates a User with extra fields (but without a company): class CustomSignupForm(SignupForm): first_name = forms.CharField(max_length=30, label='First Name') last_name = forms.CharField(max_length=30, label='Last Name') # company_name = forms.CharField(max_length=30, label='Company') def signup(self, request, user): user.first_name = self.cleaned_data['first_name'] user.last_name = self.cleaned_data['last_name'] user.save() return user How do I create a Company object inside def signup(self, request, user) function and set its FK to the created User? -

How to fix: Django calendar not displaying when trying to show user specific data
so I'm a beginner at django and I don't understand why my calendar isn't being displayed.

Serializing raw values from postgres in a custom django field
I'm trying to create a custom field to be able to store BC dates in my database. It will take a Julian Date tuple as input and convert this to a JDN through the jdcal lib. The issue is that python's built-in datetime module doesn't support BC dates, so I cannot parse db values through it. I think I've gotten my field to save correctly, but I'm not sure how to serialize a raw postgres value into my own representation, probably through a tuple of (year, month, day) to keep in line with the jdcal library. from jdcal import gcal2jd class JDNField(models.DateField): description = "A field to save JDN values as postgres `date` types" def get_db_prep_value(self, value, *args, **kwargs): if value is None: return None jd = gcal2jd(*value)[0] + gcal2jd(*value)[1] + 0.5 return f'J{jd}' def to_python(self, value): if value is None: return None return # should it go here? def from_db_value(self, value, expression, connection, context): return self.to_python(value) -

How to configure the django forms to sell custom products?
I have just started learning Django and have a simple shopping cart setup following the tutorial by Antonio Mele in his book "Django 2 by Example". I can select products and then the quantity will be an option. This works fine for generic products. What if I have custom products such as engraved pens? The buyer selects quantity of 3 but he wants different names engraved on the pens. How would I do that? Here is the code for the forms.py that controls the quantity. from django import forms PRODUCT_QUANTITY_CHOICES = [(i, str(i)) for i in range(1, 11)] class CartAddProductForm(forms.Form): quantity = forms.TypedChoiceField(choices=PRODUCT_QUANTITY_CHOICES, coerce=int) update = forms.BooleanField(required=False, initial=False, widget=forms.HiddenInput) and the relevant part of the HTML template looks like {% for item in cart %} {% with product=item.product %} <tr> <td>{{ product.name }}</td> <td> <form action="{% url "cart:cart_add" product.id %}" method="post"> {{ item.update_quantity_form.quantity }} {{ item.update_quantity_form.update }} <input type="submit" value="Update"> {% csrf_token %} </form> </td> <td><a href="{% url "cart:cart_remove" product.id %}">Remove</a></td> <td class="num">${{ item.price }}</td> <td class="num">${{ item.total_price }}</td> </tr> {% endwith %} {% endfor %} -
