How to hide tracebacks for users when an import csv fail using django import export library
I have implemented successfully import and export in my app. The only thing that I can't make to work is to hide the tracebacks for users when an import fails.

Cannot load media static file photo anymore after pushing to heroku a number of times
At the beggining it was fine to login but now after a number of times logging in and pushing changes to heroku, the static files stopped working. The error itself is "FileNotFoundError at /accounts/login/ [Errno 2] No such file or directory: '/app/media/profile_pics/obama.jpg'" Initially i thought it was the "" provided by the Login html django auth. This should redirect me to the index page. .settings.py # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/2.2/howto/static-files/ STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') # Deployment configs # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/1.11/howto/static-files/ PROJECT_ROOT = os.path.join(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles') STATIC_URL = '/static/' # Extra lookup directories for collectstatic to find static files STATICFILES_DIRS = ( os.path.join(PROJECT_ROOT, '/static'), ) # Add configuration for static files storage using whitenoise STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' # update the db import dj_database_url prod_db = dj_database_url.config(conn_max_age=500) DATABASES['default'].update(prod_db) I expected after logging in to be redirected to the index page but I get Filenotfound error even though theres no call function for any filetype. My instinct is that heroku doesnt keep static files so how can i make sure it keeps. -
How do I properly provide user field to ModelSerializer in Django Rest Framwork
I have a django Profile model as: class Profile(models.Model): created_by = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=100, blank=True) meta = models.TextField(blank=True) def __str__(self): return self.created_by And a serializer (which I know is not currently doing much) class ProfileSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = '__all__' In my update method in view, I can't ever seem to validate the serializers. This is how I am going about it: profile = Profile() profile.created_by = request.user serializer = ProfileSerializer(profile) serializer.is_valid() always returns False. And by the way, request.user is an authenticated CustomUser. I have also tried setting serializer = ProfileSerializer( instance=profile, data={'created_by':request.user} ) And many combinations thereof. What am I missing that the serializer can't be validated? Clearly there's some trouble with the user here. Extra: I am new to DRF, why is the 'created_by' field set by default when DRF seems to know who the user is? -
Unable to Get a proper result from Dict in Django Template

Generate separate translation files with django-admin
How I can generate separate *.po files for my Django project? This files used only for automatic database table fill. Table look's like: id | SKU | en | cz | ... I need only SKU and lang column to generate filter dropdown for the user. Command django-admin makemessages -a includes them to the one main file. There are large dataset with 2000+ entries in summary. So I want to split them into the parts. Especially, because most of them used only during table fill. I have tried pygettext.py command, but it doesnt generate *.po files for all website locales. And this command removes already translated content. -

Simple solutions to create an interface with a python script?
I coded a simple Python script to automate some accounting work at my internship and it has worked wonderfully. However, now that I am leaving I am a bit worried about the other accountants being able to use the same script from the command line or JupyterLab. It would be amazing if I could create a simple interface for them so they don't have to learn anything new (: the script is really simple: it imports an excel file from the user's computer, transforms into a data frame, replaces a few strings, does some calculations, deletes some columns, and outputs an excel file with the new formatting. The script can be viewed at my github here: https://github.com/brunnatorino/FEC/blob/master/ALL_app.py I even tried adding some user input functions so they wouldn't have to mess with the code, but that has also proven challenging for them to learn and remember. Is there any simple interface solutions where I can use my existing script? I would prefer to have the least amount of modifications to the code as I don't have a lot of time left in my internship. -

Unable to create a project with django-admin, the process is using a wrong path because I installed a wrong Python beforehand
When typing "django-admin startproject DEMOPROJECT" in command prompt, I'm getting the following feedback: "Fatal error in launcher: Unable to create process using '"c:\program files (x86)\python37-32\python.exe" "C:\Program Files\Python37\Scripts\django-admin.exe" startproject DEMOPROJECT'" The "c:\program files (x86)\python37-32\python.exe" is a wrong path and I'm not sure why django-admin is looking at this path. I have changed the path to my new path in the environmental variables. -
could not create unique index "credits_credit_pkey"
Initially, I had a model of Credit. But after adding models of Hypothec and AutoCredit with similar functionality, I realized that I needed to make a base model and inherit from it. When I tried makemigrations, I received a question: You are trying to add a non-nullable field 'abstractbaseproduct_ptr' to `credit` without a default; we can't do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows) 2) Quit, and let me add a default in models.py I entered 1; 1 It is not clear what the 'abstractbaseproduct_ptr' field is? Then i got You are trying to add a non-nullable field abstractbaseaction_ptr to creditaction without a default; we can't do that (the database needs something to populate existing rows).

Django filter is not using the index on Postgresql JSONField
I have a Django model that contains a PostgreSQL jsonb field: class SocialUser(models.Model): id = models.BigIntegerField(primary_key=True) data = JSONField(blank=True, null=True, db_index=True) The data field contains a username attribute. I have indexed this attribute by CREATE INDEX ON users_socialuser ((data->>'username')); When I query it via Django ORM with the id, SocialUser.objects.get(id=123) and via the pgAdmin SELECT * FROM users_socialuser WHERE id = 123 they are both fast. But when I query with the JSONField's attribute username, pgAdmin SQL query SELECT * FROM users_socialuser WHERE data->>'username' = 'abc' is still equally fast, while SocialUser.objects.get(data__username='abc') is terribly slow. It seems that the Django ORM is not using the index on the username attribute. Why is that so? Can I explicitly force an index in Django ORM? Is there a workaround for this? -
Filter subset of a queryset in Django

What I want is to get all the committees, and the meeting_set to be filtered by the date. Is there another way to do it? -
