How to display post and related comments on single page?
I am unable to design a code to render one particular post and it's related comments. The issue is maybe in views.py or the url. I have looked at multiple sources without any results. I am a novice to coding and feel like I am missing some essential point. Posts and comments are getting created correctly and all comments get the correct post_id assigned.

How to write a data migration to rename objects in the production database?
I changed the instances of "Discipline Points" to "Accountability Points" in the code but I am unable to rename these objects in the database. In a few spots, I have code that grabs a template named "Accountability Points" but this will fail to find an object matching that query because the name of these objects are not changed in the database. An example of code that grabs this is template = NotificationTemplate.objects.get(name="Accountability Points"). Currently, I'm attempting to write a data migration to rename these objects but I'm kind of unsure exactly how to accomplish this. I haven't found much on how to do this specifically, but I've looked at the RenameField migrations operation and I think the solution to my problem could be something similar. I have also tried grabbing all of the objects with the name "Discipline Points" and think a For loop would work to grab each object and rename it. # Generated by Django 1.11.6 on 2019-05-09 21:05 from __future__ import unicode_literals from django.db import migrations def change_to_accountability(apps, schema_editor): notification = apps.get_model('hr', 'NotificationTemplate') discipline = notification.objects.get(name="Discipline Points") for disc in discipline: disc.new_name = "Accountability Points" disc.save() class Migration(migrations.Migration): dependencies = [ ('hr', '0012_auto_20190509_1705'), ] operations = [ … -

How to export django model to pandas dataframe sorted by specific column
I'm working on a django web app which visualizes data stored in a SQLite in the browser using bokeh. Since I want to display the data as a stacked area plot I concluded it might be helpful to use the pandas library to save the data from my django model to a dataframe before plotting. My Django models.py includes the following model: class Activity(models.Model): def __str__(self): return self.title title = models.CharField(max_length=50) sport = models.ForeignKey(Sport, on_delete=models.CASCADE) date = models.DateField(blank=False) duration = models.FloatField() distance = models.FloatField(blank=True, null=True) description = models.CharField(max_length=50, blank=True, null=True) trace_file = models.ForeignKey(TraceFiles, on_delete=models.CASCADE, blank=True, null=True) Some example data in the SQLite db could look similar to: | id | title | date | duration | sport_id | trace_file_id | description | distance | |--------------------------------------------------------------------------------------------| | 1 | biking01 | 2019-01-01 | 183 | 1 | 16 | NULL | 142 | | 2 | running17 | 2019-01-01 | 45 | 2 | 2 | NULL | 14 | | 3 | biking02 | 2019-01-01 | 67 | 1 | 18 | NULL | 45 | What would be the best way to read from the model and convert the data to a pandas dataframe?

How to automatically start download after user clicks download button which triggers bucket event?
I am making a website on django which allows a user to upload a csv file and convert it to json. Whenever a user uploads a csv document a lambda fuction is triggered the moment the file lands on an s3 bucket where it gets converted to json and saved to another bucket. After the function generates a pre-signed url with the following code: uri_duration = 90 s3Client = boto3.client('s3') url = s3Client.generate_presigned_url('get_object', Params = {'Bucket': bucket, 'Key': filekey'}, ExpiresIn = uri_duration) My question is how could I start the download with the aid of the boto3 library automatically now that the pre-signed url is generated`? I appreciate any help you can provide -

Django GenericRelation for the update_or_create
I have an issue with using GenericRelation with update_or_create. I have the following models: class LockCode(TimeStampedModel): context_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) context_id = models.PositiveIntegerField() context = GenericForeignKey('context_type', 'context_id') class Mission(DirtyFieldsMixin, models.Model): lock_codes = GenericRelation( LockCode, content_type_field='context_type', object_id_field='context_id', related_query_name='mission' ) I try to create or update LockCode using the mission as a key: mission = .... LockCode.objects.update_or_create( context=mission, defaults={ #some other columns there } And I have the FieldError: Field 'context' does not generate an automatic reverse relation and therefore cannot be used for reverse querying. If it is a GenericForeignKey, consider adding a GenericRelation. It works when I use the context_id and context_type explicitly: LockCode.objects.update_or_create( context_id=mission.pk, context_type=ContentType.objects.get_for_model(Mission), defaults={ #some other columns there } Is it something wrong in my configuration? Or it is only single way to use GenericForeignKey for the update_or_create? -

Force password change on first login (Django)
A client requires the ability for managers to add users to a company (with a random one time password) where the user must change their password before accessing anything. I am developing the app in Django 2.2 I made a custom user, replacing username with an email address and I added a change_password bool flag to the user. My change_password form/function works properly, but redirecting does not. urls.py path('change-password/', views.change_password, name='change-password'), views.py class Login(LoginView): def form_valid(self, form): # form is valid (= correct password), now check if user requires to set own password if form.get_user().change_password: return HttpResponseRedirect(reverse('change-password')) else: auth_login(self.request, form.get_user()) return HttpResponseRedirect(self.get_success_url()) def change_password(request): if request.method == 'POST': form = PasswordChangeForm(data=request.POST, user=request.user) if form.is_valid(): form.save() request.user.change_password = False request.user.save() update_session_auth_hash(request, request.user) return redirect(reverse('user_view')) else: return redirect(reverse('change-password')) else: form = PasswordChangeForm(user=request.user) args = {'form': form} return render(request, 'users/change_password.html', args) The expected behavior is to redirect to change-password if the change_password flag is True, however, while the app does redirect to change-password, upon Submission the following error is thrown: NotImplementedError: Django doesn't provide a DB representation for AnonymousUser. If I add the decorator @login_required to my change_password function this error goes away, however, I am redirected back to the login page with … -
csv file going from 316 KB to ~3GB during django app run time then back instantly once app is terminated
The explanation is a bit long, but most of this is to give some background regarding my problem (the problem is probably not Python related, but having extra information wont hurt): I am currently working on a django application. The application window (browser) has two iframes each taking 50% of the screen. On the left-hand side there will be snopes (fact-check website) pages displayed and on the right-hand side one of the pages linked in that specific snopes article will be displayed. A form in the bottom of the app will let the user choose and post whether the RHS page is a source of the claim in the snopes article or not (there is also "invalid input" or "I dont know"). Submitting calls a function which tries to get the other links of the current snopes page, and if there is none, get any pages annotated (in this priority) twice, once, or least (so 0 then 3 then 4 .....). This is done by using a count.csv which simple stores how many each page+link combination has been annotated (as snopes articles can repeat and so can linked sites). The header of count.csv is : page source_url count The pages …
