How do I get Task.project to be editable during creation but non editable during updating on a database/model level? Approaches so far: The editable=False option This works on the admin/form level, not on the database level Making a field read-only in django admin This also works on the admin/form level, no on the database level -

Shopify GraphQL mutations
I'm trying to create an order with Shopify's Storefront API and Django with Python Requests. So far I can't get anything except errors. My code is: mutation = """ { checkoutCreate(input: { lineItems: [{ variantId: "Z2lkOi8vc2hvcGlmeS9Qcm9kdWN0VmFyaWFudC8xODE0ODY4MTQ0OTU4NQ==", quantity: 1}] }) { checkout { id webUrl lineItems(first: 5) { edges { node { title quantity } } } } } } """ data = (requests.post('https://catsinuniform.myshopify.com/api/graphql', json={'mutation': mutation}, headers=headers)) The error I get with this is <title>bad_request - Parameter Missing or Invalid</title> Which seems to be saying I need to submit the title parameter, but this doesn't work either - whether I use the title for this product variant or the product title. I assume you would pass the title in this line like so? lineItems: [{ variantId: "Z2lkOi8vc2hvcGlmeS9Qcm9kdWN0VmFyaWFudC8xODE0ODY4MTQ0OTU4NQ==", quantity: 1, title: "title"}] -
Divio Live server not serving the static files when DEBUG=False
I am running a website in Divio Cloud. My Test server serves the static files fine but my Live server gives 404. When I switch DEBUG to True on the Live server it starts serving the static files fine. When the Live server starts, it has this in the log: [uwsgi-static] added mapping for /static/ => /app/static_collected Shouldn't that take care of serving the static files correctly? -

django logging: DJANGO_COLORS does nothing (macos)
I'm on MACOS terminal. I'm trying to print colored output running a django test. I'm setting, from the terminal export DJANGO_COLORS="error=yellow/blue,blink;notice=magenta" (also tried DJANGO_COLORS="light" and others. Then, from django test code print(os.environ['DJANGO_COLORS']) logger.error("test") and run python manage.py test The first line verifies that the environment variable is set correctly. But the next line prints normally, without coloring. What is wrong? -
Running a python script once after app server starts - Django, Docker-Compose
Desired outcome: After I run docker-compose up I want the server to start (docker-compose runs the database and web services) and then after the server is up and working run a python script that contains a web scraping code which puts the scraped contents into the DB (and only run it once). The code is using Django models to store the data in DB. Problem: After running docker-compose up the database and server are run correctly, I can access the website on localhost and get the API responses, but it seems the scraping script is never executed. I have found a way to run the code using ready function built into Django before, but it does not work as intended (it stops the server from running until the whole scraping completes which is not optimal as I want the scraping to run in the background). When I tried using a separate service to run the script, even using depends_on did not work, the service was still being run as soon as web did and then fail due to "File not found". What would be the right way to go about doing this? Code: docker-compose.yml: version: '3.6' services: db: image: postgres:10.1-alpine … -
Django CheckboxSelectMultiple - restore data in template
I have a model form in django which looks like this: class ApplicationStep12(forms.ModelForm): race = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(attrs={'class': 'myselect hmda'}), choices=RACE, label='Race') class Meta: model = TestApplication fields = ('race',) race field in model is stored as a CharField In template each form checkbox element is rendered separately like this: <div> {{ form12.race.label_tag }} </div> <ul class="myselect"> <div class="md12"> <li class="md4"> {{ form12.race.0 }} </li> <li class="md4"> {{ form12.race.1 }} </li> <li class="md4"> {{ form12.race.2 }} </li> </div> <li class="md12"> {{ form12.race.errors }} </li> </ul> After submit and validation data for several selections stores as list of selected values : ['1','3'] After page return and refresh only this field can not populate from database an console check shows that no checked props are present for this block.

In Django, prefilling DateField is not working when setting the widget to DateInput
I wish to prefill a form field with a specific date. I have a CreateView: class CreateEventView(CreateView): model = Event template_name = 'events/form.html' form_class = EventForm def get_initial(self): initial = super(CreateEventView, self).get_initial() initial['start_date'] = datetime.date(day=int(day=2,month=11,year=2018)) return initial If I use this ModelForm, it displays the prefilled date in a text field (as expected): class EventForm(ModelForm): start_date = DateField() # ... But I wish to use a nice date picker widget. But then prefilling does not work any more: class EventForm(ModelForm): start_date = DateField(widget=DateInput(attrs={'type': 'date'})) # ... Why is that so? What can I do about this? Is this behavior somewhere documented? -
add environment variables to activate file in a virtualenv for a Django project
I recently clone a django project and in the README file said that : Edit .venv/bin/activate and add this environment variables. :: export DJANGO_SETTINGS_MODULE="thissite.settings.development" export LD_LIBRARY_PATH=/usr/local/lib export LC_ALL='en_US.UTF-8' export LANG='en_US.UTF-8' So i built this virtual env and in this step should i just simply copy and past this environment variables to the activate file(where exactly?) or what? The activate file : # This file must be used with "source bin/activate" *from bash* # you cannot run it directly deactivate () { unset -f pydoc >/dev/null 2>&1 # reset old environment variables # ! [ -z ${VAR+_} ] returns true if VAR is declared at all if ! [ -z "${_OLD_VIRTUAL_PATH+_}" ] ; then PATH="$_OLD_VIRTUAL_PATH" export PATH unset _OLD_VIRTUAL_PATH fi if ! [ -z "${_OLD_VIRTUAL_PYTHONHOME+_}" ] ; then PYTHONHOME="$_OLD_VIRTUAL_PYTHONHOME" export PYTHONHOME unset _OLD_VIRTUAL_PYTHONHOME fi if [ -n "${BASH-}" ] || [ -n "${ZSH_VERSION-}" ] ; then hash -r 2>/dev/null fi if !

Django Rest framework swagger base url
I have successfully running my rest framework swagger on localhost.. These was my rest framework swagger localhost screenshoot. It has run successfully. Now i want to deploy it on server testing. These is the screenshot result of my testing deployment. As you can see the base path changed and served from localhost, the schemes read the right configuration which is https schemes, and the application run in the right domain which is api.executivemafia.com, so that's not problem. The problem come when I want to try the API. The server point is localhost. So it's make my endpoint request become 'https://127.0.0.1:8000/instagram/hello". My questions are: Why the rest framework swagger still read localhost although my application already served in https://api.executivemafia.com/docs/? Fyi, I set the proxy pass nginx to locahost:8000 because my gunicorn run on localhost:8000. Can the base url rest framework swagger testing server using my testing server domain end point ? If it's able to, how to do it? Any help and reference will be appreciated. Thank you Guys!! Regards, Meikelwis Wijaya -

Django 2 Angular 6 compiled static files always route to static folder
I have a Django 2 + Angular 6 project. I have a build process that moves my compiled JS files into the Django's static folder. However, whenever I go to a link, say http://127.0.0.1:8000/#/upload, the browser always redirect me to http://127.0.0.1:8000/static/my_project/#/upload.. What is happening? I'm using hash location strategy. My page still works, but whenever I refresh at the latter URL or visit it directly, I get an 404.. My urls.py file is like this: urlpatterns = [ path('', IndexView.as_view()), path('admin/', admin.site.urls), path('api/v1/', include(router.urls)), ] The first url pattern matches an IndexView, which is just a TemplateView with this index.html: {% load static from staticfiles %} <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <link rel="icon" type="image/x-icon" href="{% static 'favicon.ico' %}"> </head> <body> <app-root></app-root> <script type="text/javascript" src="{% static 'uploader/runtime.js' %}"></script> <script type="text/javascript" src="{% static 'uploader/polyfills.js' %}"></script> <script type="text/javascript" src="{% static 'uploader/styles.js' %}"></script> <script type="text/javascript" src="{% static 'uploader/vendor.js' %}"></script> <script type="text/javascript" src="{% static 'uploader/main.js' %}"></script> </body> </html> -
Transaction.atomic while overwriting save() method in Django model?
