How to setup Django logging to log to console and Debug Toolbar same time?
I try to setup logging in Django to use console and Django Debug Toolbar. By default this line logger.debug('XXXXX') log to DDT and console stay empty. With this setup LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console': { 'level':'DEBUG', 'class':'logging.StreamHandler' }, }, 'loggers': { '': { 'handlers': ['console'], 'level': 'DEBUG', }, }, } logs appear in console, but disappear from DDT How to make it works in both destinations? -
What's the meaning of order in a django request processing?
OVERVIEW Consider the below urls.py: from django.contrib import admin from django.urls import re_path, include from django.conf.urls.static import static from django.conf import settings from django.contrib import admin from django.urls import path # a) urlpatterns = [ path('admin/', admin.site.urls), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) # b) # urlpatterns = [ # path('admin/', admin.site.urls), # ] print(urlpatterns) As you can see we got 2 url lists, whose __str__ representation is: a) [<URLResolver <URLPattern list> (admin:admin) 'admin/'>] b) [<URLResolver <URLPattern list> (admin:admin) 'admin/'>, <URLPattern '^media\/(?P<path>.*)$'>] PROBLEM If I make the same request to localhost:8000 it's producing 2 different outcomes for the abovementioned url lists: Using a) , I'll get a 200 response: Using b) , I'll get a 404 response: QUESTION After reading the section "How django processes a request" I've observed it says in point 3): Django runs through each URL pattern, in order, and stops at the first one that matches the requested URL. What does the concept of "order" means in this context? For instance, let me put you an analogy of what I understand of "order processing", if i declare a couple of lists (b is extended from a), a=[0,1,2,3]; b=a+[4,5,6] and then i do a.index(2)=2, b.index(2)=2, that type of order … -

django context processor form not showing errors when submitting
I`m using context processor to render form to the base template in my project and the form seems to work ok, except it doesnt show any errors for required fields being blank and etc. The page is simply reloaded even if fields are not filled in. I used this approach in other project before, and it worked just fine, but now I cant really figure out what happened and why it is like so. Here is my forms.py: from django import forms class VersionSelectorForm(forms.Form): mode = forms.ChoiceField(widget=forms.RadioSelect(), choices=(('live', 'Live'), ('history', 'History')), initial='live', required=True, help_text='Required') date = forms.DateField(widget=forms.TextInput(attrs={'class': 'datepicker'}), required=True, help_text='required') def clean(self): cleaned_data = super(VersionSelectorForm, self).clean() mode = cleaned_data.get('mode') date = cleaned_data.get('date') if mode == 'history' and not date: msg = 'Date should be picked if \'History\' mode selected' self.add_error('date', msg) view.py: from django.shortcuts import redirect from .forms import VersionSelectorForm def select_version(request): if request.method == "POST": form = VersionSelectorForm(request.POST) if form.is_valid(): print('I am valid') mode = form.cleaned_data["mode"] date = form.cleaned_data["date"] if mode == "History": request.session['selected_date'] = date else: request.session['selected_date'] = None else: form = VersionSelectorForm() return redirect(request.META['HTTP_REFERER']) context_processors.py: from .forms import VersionSelectorForm def VersionSelectorFormGlobal(request): return {'version_selector_form': VersionSelectorForm()} urls.py: from django.contrib import admin from diagspecgen import views urlpatterns = [ url(r'^admin/', … -
jQuery not found with Django RGBField
The project I'm working on uses an RGBField, which inserts this script into the template (which is deep in the bowels of django somewhere because I can't find where it lives): <script type="text/javascript"> (function($){ $(document).ready(function(){ $('#id_color').each(function(i, elm){ // Make sure html5 color element is not replaced if (elm.type != 'color') $(elm).colorPicker({"colors": ["f1c40f", "2ecc71", "9b59b6", "e74c3c", "34495e", "3498db", "1abc9c", "f39c12", "d35400"]}); }); }); })('django' in window && django.jQuery ? django.jQuery: jQuery); </script> In the console I'm getting an error: Uncaught ReferenceError: jQuery is not defined I'm unable to inspect where the error is happening, but removing the RGBField prevents the issue. Jquery is used in the project, and if I use jQuery in the template itself it works fine (so it's not a problem with the template per se). I've added django-jquery to the project, and included {% load staticfiles %} at the start of the template. Does not resolve the problem. I've been ignoring the whole thing happily but now I need to write a cypress test with this page and the error is blocking the test. Is there a way in cypress to ignore this error? Or is there a way to prevent the error from happening in the … -
Django formset - validate input based on user cookie?
I have a Django form (TestForm) that contains a single field, quantity. I also have a Django formset (TestFormset) that contains multiple instances of my TestForm. I want to write a custom clean() method for my TestFormset that validates that the sum of the quantities specified within my multiple TestForms is equal to a number, max_quantity, stored in a session variable. I know that I am able to perform this validation within views.py (for example, after my formset is validated and cleaned, I could manually sum up the 'quantity' variables in my TestForms and check to ensure that they are equal to request.session['max_quantity'], throwing an error if any problems are found). But ideally I'd love to move all my form validation logic into the clean() method of forms.py. However, I can't figure out how to pass an external value into my Formset that is not linked to one of its individual forms. Is this possible to do? forms.py from django.forms import BaseFormSet class TestForm(forms.Form): quantity = forms.IntegerField() class BaseTestFormset(BaseFormset): def clean(self): if any(self.errors): # Don't bother validating the formset unless each form is valid on its own return quantity = 0 for form in self.forms: quantity += form.cleaned_data['quantity'] # IF … -

Django - Null value in column "imageLink" violates not-null constraint
I've been trying to setup an upload possibility for a form (with the intent to upload pictures) to a database, which is linked to other data in the list but every time I try to run it, it won't ignore the null that is suppose to be the picture. I've been reading up and trying to get this fixed for a solid day and a half but there isn't a lot of documentation to be found on this subject.

Trying to learn inline formsets, not going well
I'm trying to get a very minimal inline formset added to a existing form. Basically I have the model Builing and Gallery with a foreign key to Building. I have already set up a basic BuildingCreateView that specifies the form building_form via form_class. I have created a simple GalleryFormSet but I can't get it show in the template.

Google Chrome opens empty new window when clicking Django dev server link
I had a Django project running perfectly using Python 2.7. Now I switched to Python 3 and whenever I click the link shown when I start the Django development server, google chrome opens a new, empty window where previously it opened a new tab in the existing window (which also contained the web application I was trying to run). I'm not sure this has anything to do with switching Python versions because I remember seeing this issue before when I wasn't doing anything with Python. Does anybody have clue? It's probably something very simple. Cheers -
What is a modern approach to deploy Django app?
I am developing a django application and reached the stage where the app has to be deployed to the production. I do not have too much DevOps experience and hence was doing some research. However, most of the proposed methods were 6-7 years old. Therefore I was wondering if anyone could suggest the modern approach to ship the django-based product given my requirements: The application will be used by companies with 1-1000 employees. Each company will store sensitive data. There should be no more than 100 different companies. We have a scheduler to execute a few machine learning tasks in the background. Business logic is quite trivial, no fancy algorithms. More specifically: Should every company have its own instance running with separate database? If I run everything on a single server and DB, is it okay to store sensitive data of all companies on the same DB? If I run everything on a single server and DB, will the server be able to cope with the traffic given my requirements? Who would provide the best service? Which one is the easiest to set up and run? I have deployed a few apps on AWS, but it was quite clumsy and … -

File Upload Handler gives chunk with size less than specified
A very unusual thing is happening with Django file upload handler. I followed the documentation to write a custom handler so I could encrypt raw_data as I received it and write it to the file object. I didn't change the default chunk_size which is 64KB. My code worked fine with small files. But when I send files greater than the chunk size, the raw_data I receive does not have a length of 65536 as it should be for 64 KB chunk size, rather it is somewhere between 64000 to 65000. This hurdle is preventing me from being able to encrypt large files. Help. -

Django: How to set a property in a model using @property
