Django queryset update migration
I'm trying to optimize a migration, it's taking too long, about 15 minutes every time you try to run it, because there is a lot of data on this table. It's an old database that have dates like this '14102019' (%d%m%Y) as String, and need to convert them to DateField. I created a DateField for both. Database is MySQL. dtobito and dtnasc are the old strings that need to be converted data_obito and data_nasc are the new DateFields What works (very slowly): def date_to_datefield(apps, schema_editor): Obitos = apps.get_model('core', 'Obitos') for obito in Obitos.objects.all(): if obito.dtnasc and obito.dtnasc != '': obito.data_nasc = datetime.strptime(obito.dtnasc, '%d%m%Y') if obito.dtobito and obito.dtobito != '': obito.data_obito = datetime.strptime(obito.dtobito, '%d%m%Y') obito.save() What doesn't work: Obitos.objects.update( data_nasc=datetime.strptime(F('dtnasc'), '%d%m%Y'), data_obito=datetime.strptime(F('dtobito'), '%d%m%Y') ) What could work, but I don't know how: Obitos.objects.raw(""" UPDATE obitos new, ( SELECT STR_TO_DATE(dtnasc, '%d%m%Y') AS dtnasc, STR_TO_DATE(dtobito, '%d%m%Y') AS dtobito, FROM obitos ) old SET new.data_nasc = old.dtnasc SET new.data_obtio = old.dtobito """) -

What did my pipenv disappear after python upgrade?
I had an existing project an everything was fine. As Heroku seemed to need a specific python runtime version for deployment, i upgraded python (windows 64) to 3.7.4 When running pipenv shell in my usual folder, i have this message : C:\Users\henry\Desktop\testldc>pipenv shell Creating a virtualenv for this project… Pipfile: C:\Users\henry\Desktop\testldc\Pipfile Using c:\users\henry\appdata\local\programs\python\python37\python.exe (3.7.4) to create virtualenv… [=== ] Creating virtual environment... but this message keeps running (up to 20 minutes)until it freezes ! I've tried to run pipenv shell on another previous project folder, and the problem is the same : installation i didn't ask for, and stuck during the installation. Thanks for your help ! I just wanted to run my usual virtual environment with a newer python version. -
How to query two models under a class view, get specific attributes associated with each models and compare one record against another
I have two models Job and Applicants, the Job model has an attribute years_of_experience and the Applicants model has an attribute applicant_experience.

Not able to get the data selected form Django: ChoiceField
My application from an uploaded CSV file, reads header values and passes these headers into another class which extends Form. The goal is to get the selected value from the ChoiceField. The definition of selected is - current value displaying from the ChoiceField, should be considered selected. I am able to read the header values list. But when I am trying to print the selected choice field value expense_form.is_valid() returns False. My question is how could I get the selected data/value out from the ChoiceField.

Can we define models.CASCADE only without using on_delete?
As I know is that when we defining foreign key in django we can set like on_delete=models.CASCADE. Recently I have seen code like content_type = models.ForeignKey(ContentType,models.CASCADE). My question is that does django allow to define models.CASCADE without using on_delete ? OR if we define like above does it work differently? content_type = models.ForeignKey( ContentType, models.CASCADE, verbose_name=_('content type'), ) -
Generating JSON progress events from Django file upload
I'd like to display an upload status bar in my GUI when uploading a (large) file to my Django backend. My problem is that the 'onprogress' event appears only once when the upload is finished (both in the Django development server as well as in the Apache server (Windows).

Docker: execute django migration into a db container from inside of the web container
I run a CI pipeline in gitlab. The stage executes several steps: First I start db container: docker run --name db -p 5432:5432 \ -e DJANGO_SETTINGS_MODULE=<myapp>.settings.postgres -d postgres:9.6 Then I check if it worked: docker inspect db true Note that I specify a non-default settings file (which contains my db credentials) Now I build web container with Django 2.2 inside and feed it the DB credentials of the postgres container : docker build --pull -t test_image . --build-arg DB_NAME=<mydbname> --build-arg DB_HOST=db --build-arg DB_USER=<mydbuser>--build-arg DB_PASS=<mydbpassword> That runs Dockerfile sequence of may steps and at some point arives to DB migration: RUN python manage.py migrate --settings .settings.postgres That invariably chokes with this error: django.db.utils.OperationalError: could not connect to server: Connection refused Is the server running on host "db" (127.0.0.1) and accepting TCP/IP connections on port 5432? Which means to me that the name I gave to the postgres container ("db") does not mean anything inside this (web) container.

Gunicorn no wsgi module
I'm following this tutorial this time: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-centos-7 But I think it misses out a step, as I am unable to test the dev server is running using manage.py runserver 0.0.0.0:8000, but I never have before, so no biggie there, but I am unable to get gunicorn working as there is no wsgi.py module in my project.

replace spaces with % in django or python app
im having a hard time fixing this one. i have a search function that will look for campaign name or campaign launcher name. for example if a user look for all campaigns launched by john doe. i want to enclose all spaces with '%' (%john%doe%) expected. campaigns = Campaign.objects.filter(title(re.sub('/\s/g ', '%', search)) | launcher(re.sub('/\s/g ', '%', search))) i also tried campaigns = Campaign.objects.filter(title(re.sub(' ', '%', search)) | launcher(re.sub(' ', '%', search))) but my code is not doing the right thing. im getting `camp`.`name` LIKE '%john doe%' OR `user`.`name` LIKE '%john doe%' and if i did the search.replace(" ", "%") im getting `camp`.`name` LIKE '%john\\%doe%' OR `user`.`name` LIKE '%john\\%doe%' any help will be much appreciated. -
Django: QuerySet with group of same entries
My goal is to show for a specific survey the Top 10 "Entities" per question ordered from high to low by salience. A survey has several questions. And each question has several answers. Each answer can have several entities (sometimes the same name (CharField), sometimes different names). I thought the following final result makes sense: [ 5: # question.pk [ { 'name': 'Leonardo Di Caprio', 'count': 4, # E.g. answer__pk = 1, answer__pk = 1, answer__pk = 2, answer__pk = 3. Leonardo Di Caprio was mentioned twice in answer_pk 1 and therefore has entries. 'salience': 3.434 # Sum of all 4 entities }, { 'name': 'titanic', 'count': 5, 'salience': 1.12 }, { 'name': 'music', 'count': 3, 'salience': 1.12 } ], 3: # question.pk [ { 'name': 'Leonardo Di Caprio', 'count': 5, 'salience': 1.5 }, { 'name': 'titanic', 'count': 4, 'salience': 1.12 }, { 'name': 'music', 'count': 2, 'salience': 1.12 } ], ] Now I am struggling to write the right QuerySet for my desired outcome. Anyone here who can help me with it? I came to the point that I probably have to use .values() and .annotate(). But my results are quite far away from what my goal ist. Here … -

Combination of foreigh keys and pre-defined values as choices for Django model field
A ForeignKey field (let's call it tc) in one of models (let's call it Venue) stores reference to terms and conditions model (let's call it TC) where different versions of document are stored. This way every Venue can select one of versions of tc that suits their needs. class Venue(models.Model): tc = models.ForeignKey( 'my_app.TC', on_delete=models.CASCADE, help_text=_('Version of tc used by this venue') ) Records in TC table are added frequently so if given Venue wants to use latest version of document someone needs to manually update it via django admin. This is a poorly though solution because there are dozens of Venue records in database and they all have different approaches to tc usage: some of venues want tc to be updated automatically to latest version some want/need to bump up their tc version manually some venues do not use tc at all The goal that needs to be achieved is having 2 default options for each Venue: 1. ---- (blank: venue does not use any `tc`) 2. Latest (venue automatically uses latest version of `tc` available` And unspecified number of available tc options (for example foreign keys to TC model) 1. v1.0.0 2. v2.1.0 3. ... So list of … -
