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 … -

Django: Module not Found on Azure App Service - Azure DevOps CD
I am looking to set up a simple Django application on Azure App Service (Linux OS) by running an Azure Devops Build and Release pipeline. The application builds and creates a release without a problem. However when the application has been released it runs into runtime errors. 2019-10-15T09:48:16.161816610Z ModuleNotFoundError: No module named 'django' I run pip3 install -r requirements.txt as part of the bash post deployment script, and requirements.txt contains Django but it claims the requirement is already satisfied. Or if I bash into the App Service and run the same command it get the same message with the requirements already being satisfied. Therefore my question is, why am I receiving a ModuleNotFoundError? -

Django-allauth URL Returns callback error for github despite correct url
I am trying to implement all-auth using Github in my django project. I have set the callback url as per this tutorial.

Heroku not correctly installing tulipy from requirements.txt
When deploying my django app on Heroku, I have a ModuleNotFoundError happening when it tries to install tulipy package from requirements with pip. It says No module named 'numpy' when importing numpy but it is the first package on the requirements.txt list so it should be installed first. The app is deploying fine without tulipy package. I tried calling another requirements file with -r ./requirements-prior.txt containing only numpy but it doesn't work. How can I force Heroku to install numpy before tulipy? Full error message Thanks -
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 … -
How to redirect users after password change django 2?
I have a password change view in my project. Instead of the default django password_change_done/done/ I want users to be redirected to my custom page eg homepage.

Django application failing randomly after updating python and django
here is my problem: I have a Django application that I am trying to update from python2.7 / Django 1.8 to python3.7 / Django 2.1 In my browser, I can access the django admin with no problem, but when I try to access the website it often fails : in Google Chrome, "This site can’t be reached", with either ERR_CONNECTION_RESET or ERR_SOCKET_NOT_CONNECTED. It does not always fail though. There is apparently no pattern : sometimes it loads well, then I refresh and it does not, then I refresh again and it does load well again... The stack : python3.7, Django2.1, nginx, docker, redis It would be great if you had any clue -

Private static files on AWS with django app
I am running a django application and would like to host my static files (which includes my documentation with sphinx) on AWS. I configured everything and it works fine. It only works though if my bucket has public permissions. I do not want my static files be accessible to the public though. Yet I think that static files must be public on AWS. Is there any way of restricting the access to the bucket and still use it to serve my static files? I know that I can restrict the traffic to certain IP addresses, but since I am running my app on Heroku I don't have a fixed IP but DNS. I can't believe there is no way of hosting private static files. Or maybe do I need a different provider than AWS? Help is highly appreciate, I am stuck with this since forever. Thanks so much in advance... -
