ProgrammingError after reverting migration after AttributeError
I did the migration after adding SourceBook and SourceBooksOrderable and that worked. Then I managed to add two snippets in wagtail admin. But when I tried to add them into the BlogPage in admin, I got an AttributeError. Thinking that it was somehow a problem with the migration, I reverted migrations using python manage.py migrate blog 0001. Now I get a ProgrammingError under the snippet in admin. Tracebacks, models.py and migration files are below. How can I fix this? blog/models.py from django.db import models from modelcluster.fields import ParentalKey from modelcluster.contrib.taggit import ClusterTaggableManager from taggit.models import TaggedItemBase from wagtail.core.models import Page, Orderable from wagtail.core.fields import StreamField from wagtail.core import blocks from wagtail.admin.edit_handlers import FieldPanel, StreamFieldPanel, MultiFieldPanel, InlinePanel from wagtail.images.blocks import ImageChooserBlock from wagtail.images.edit_handlers import ImageChooserPanel from wagtail.snippets.models import register_snippet from wagtail.snippets.edit_handlers import SnippetChooserPanel richtext_features = [ 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', "ol", "ul", "hr", "link", "document-link", "image", "embed", "code", "blockquote", "superscript", "subscript", "strikethrough", ] class BlogListingPage(Page): """Listing page lists all the Blog pages.""" template = "blog/blog_listing_page.html" subpage_types = ['blog.BlogPage'] custom_title = models.CharField( max_length=255, blank=False, null=False, help_text='Overwrites the default title', ) content_panels = Page.content_panels + [ FieldPanel("custom_title"), ] def get_context(self, request, *args, **kwargs): """Adding custom stuff to our context.""" context = … -
Django HttpOnly cookie doesn't protect but user can stop it if a malicious code didn't take an action yet. Am i right?
So in my understanding there are two ways of an XSS attack. Attacker user sends malicious Javascript code to backend and when another user opens it will have access to that users data. It is generally prevented with framework itself but you can also encode the data before sending to the backend and filter them before storing them into database in the backend side. When you open want to access it in the client side you decode it again. Browser extensions. Browser extensions have a all the access of client side. They cannot access HttpOnly cookies. But they can still send requests to backend, post something etc. If you use HttpOnly cookie once a user disables extension it will not have the control anymore. Am i right or is there another way of making an XSS attack? -

Django formsets in formsets
I am creating a quiz app. A quiz has one or more questions, each question has one or more images. I've already used django-dynamic-formsets to allow the user to create/delete multiple questions. However, I am struggling to find a method that allows the user to upload images for specific questions, and then for Django to recognise which images 'belong' to each question. Because a question could have multiple images (up to some unknown amount) I cannot just hard code multiple fields in my question model. My current code has a model for questions, and models for 'choices' which has a foreign key to a question model. -

nginx + django + haystack = Server Error (500)
I've cobbled together a small blog application in Django using Haystack with Whoosh backend for search. It runs nicely in development server (on the laptop) but search fails when site runs in nginx on a server (rpi). I can access search page but any search results in Server Error (500), no additional info available from either nginx or django logs. I had RealtimeSignalProcessor on but turned it off - no change. Any pointer on how to attempt to debug this would be great. -

Django-Heroku app not saving data on JawsDB mysql (Long polling)
so I created a django project to imitate an asynchronous data stream using ajax and long polling. Everything works fine on the local server however it doesn't after I deployed it on heroku. There is still buttons to control LED (IoT) however there's no readings. The error said failed to load resource which i believed that it has smtg to do with database connection. I'm not using sqlite3, in fact i'm using mysql. I know that it's not possible to call a local database on heroku app so I'm using the jawsdb mysql add ons and i configured my settings.py according to the user, password and also host. I am able to connect to it using xampp however I can't see it auto saving data which it should be doing whenever my esp32 send a data to it. Would be great if someone could provide me some answers. I have a thoughts that could be the issue. The initial postgresql is the main database? I added the add ons and configured it on my django settings.py and pushed on heroku. However I'm not sure do i need to use heroku to sort of like set the mysql as my main … -

Force Download existing JSON file instead of displaying it with Django
My webpage has a functionality that lets users request fairly large json files (3MB+) to be generated. The generation process takes some time and I send them an email with a download link once it is ready. My problem is that clicking the download URL will open the content of the json file in the browser instead of starting a download dialog. I have found this question: Serving .json file to download but the solution reserialize the json file into the response: mixed_query = list(invoices) + list(pcustomers) json_str = serializers.serialize('json', mixed_query)) response = HttpResponse(json_str, content_type='application/json') response['Content-Disposition'] = 'attachment; filename=export.json' As the JSON file already exists, I do not want to rewrite it entirely within the response. I just want users to download the already generated file. How can I force the URL to start a download when reached? I am using Django 3.1, with Python 3.6 -
