Django runserver error after startproject
I'm new to Django and web frameworks in general. Right off the bat, I can't seem to run the server after django-admin startproject mytestsite. I've tried this with and without a virtual environment, and with Python's built-in virtual environment tool as well as virtualenv.

Pass object id to view from form submission

how can I convert an incorrectly-saved bytes object back to bytes? (python/django)
I've downloaded some web pages with requests and saved the content in a postgres database [in a text field] using Django's ORM. For some sudocode of what's going on, here ya go: art = Article() page = requests.get("http://example.com") art.raw_html = page.content art.save() I verified that page.content is a bytes object, and I guess I assumed that this object would automatically be decoded upon saving, but it doesn't seem to be... it has been converted to some weird string representation of a bytes object, ostensibly by Django. It looks like this in the interpreter when I call art.raw_html: 'b\'<!DOCTYPE html>\\n<html lang="en" class="pb-page" And if I call it with print I get this: b'<!DOCTYPE html>\n<html lang="en" class="pb-page" And for the life of me I can't re-encode it to a bytes object, even if I trim off the leading b' and trailing '. I feel like there's an easy solution to this and I feel like an idiot... but after lots of experiments and googling, I'm not figuring it out. Incidentally, if I manually copy what's returned from the print statement (like with my cursor), I can convert the clipboard contents back to a bytes object just fine and then decode it into … -
DRF ListSerializer and FieldSerializer
I use django rest in my project and until now for list of objects I used ListSerializer, when I needed to have min length and max length of list I googled and reached to ListField. Before that my code worked fined without any error and misbehavior. Now I use ListField for my list field serializer, But I didn't get when to use ListSerializer? Can someone explain the difference between ListSerializer and FieldSerializer? My sample code with ListSerializer: tags = serializers.ListSerializer(child=serializers.CharField(allow_blank=False), required=False) My sample code with FieldSerialzier: open_hour = serializers.ListField(child=serializers.DictField(), max_length=7, min_length=7) -
How to make django-summernote editor's height grow as content increases
I have a django-summernote widget SummernoteWidget implemented but now I wish to allow the height of the editor to grow as the editor content grows as described in the summernote documentation here I have tried removing the height property from the django_summernote\settings.py file because in the documentation it states that the height will automatically grow when there is no height property declared. My apps settings.py looks like this: SUMMERNOTE_CONFIG = { "summernote":{ "toolbar":[ ["state", ["undo", "redo"]], ["insert", ["table", "hr" ]], ["style", ["bold", "italic", "underline", "clear"]], ["font", ["style", "fontsize", "color", "strikethrough", "superscript", "subscript"]], ["paragraph style", ["ol", "ul", "paragraph", "height"]], ] } } Is there a way to make the height of the editor grow as the content area content grows? -
Test interoperability between Django and a client application
I have a project that includes a Django web service exposing a rest API (using DRF) and an python application that issues requests (using urllib.request) to that server. They are both in the same github repo and share a set of Travis-CI jobs, where some jobs test the Django site and other jobs test the python application. After writing several tests for each individually, I would like to create some tests that will trigger the entire flow, starting somewhere in the application code then issue a request that will directed to the django app which will in turn return a response that will be processed by the application. I believe I need some kind of a hook somewhere along my request.Request or opener.Open functions that normally send the HTTP request, and I'm certain this has been done before. I couldn't find anything on Django's documentation for that. -

How to pre-populate the chosen box of the FilteredSelectMultiple in Django for user side?
I am trying to have the user's chosen item be shown in the FilteredSelectMultiple chosen box when he/she revisits the page. I have managed to save it to the database and had tried appending options via javascript but that didn't help. I have seen a stackoverflow question on how to pre-populate the same widget as well but that seems to be for the Admin side only. My FilteredSelectMultiple widget is on the user side.

How to add an extra field to a Django ModelForm?
So I'm working on an admin page. I'm registering the form with admin.site.register. And I want to add an extra field to the form, which will let me populate a TextField with a file contents.

I am trying this: class PersonForm(forms.ModelForm): extra_field = forms.FileInput() class Meta: model = Person fields = '__all__' but the field is not showing. Any ideas? Also I have no clue where to access the file contents and populate the TextField with that before saving the model. Thanks in advance. -
Python Twitter APi using OAuth not providing email
I need to use Twitter API to allow Twitter login for my site. Using Python (Django), I have been able to get the user's name and username and other relevant data, but not the user's email. I have already checked the box for email permission on apps.twitter.com, and the user is prompted that his/her email will be used when login in. But the request doe not contain the email. Here's my code: def get_user_details(self, response): """Return user details from Twitter account""" try: first_name, last_name = response['name'].split(' ', 1) except: first_name = response['name'] last_name = '' print response return {'username': response['screen_name'], 'email': 'response['email']', 'fullname': response['name'], 'first_name': first_name, 'last_name': last_name} The response that is printed contains and screen_name and name, but not the email. I know my tokens are correct because I get all the other data. This is the API call I'm making: TWITTER_CHECK_AUTH = 'https://%s/1.1/account/verify_credentials.json?include_email=true&include_entities=false&skip_status=true' % TWITTER_SERVER Any ideas? -
Django API works locally but not when deployed on Elastic Beanstalk
I'm working with Django Rest Framework and Django Rest Framework JWT, but I'm running into an issue in regards to local behavior vs external behavior. When I make a POST request to get a JWT token, everything works as desired both locally and on my EC2 instance. However, once I have the token, when I make a request to my server that requires authentication, only my local server returns the expected response. On my deployed server, I get the following error: {"detail":"Authentication credentials were not provided."} What I've tried so far: Editing http.conf by sshing into my server and enabling WSGIPathAuthorization. (saw a similar post here and tried the solution) What could be causing this behavior? My local machine and my deployed code are identical, leading me to believe that this has something to do with server-side configuration. All help is appreciated. Thanks! -
How To Get Django Form To Validate Multiple Fields Together

Wagtail: Can I display a Page's siblings on the admin side?
Is it possible, within Wagtail, to query a Page's siblings, then display them on the Pages admin page in checkboxes? So far, I have: class MyPage(Page): def siblings(self): siblings = MyPage.objects.live().sibling_of(self) return siblings def sibling_titles(self): sibling_choices = () for sibling in self.siblings: title = sibling.title title_slug = slugify(sibling.title) sibling_choices.append(tuple((title_slug, title))) return sibling_choices CHOICES = sibling_titles sibling_checkbox = forms.MultipleChoiceField( required=False, widget=forms.CheckboxSelectMultiple, choices=CHOICES, ) sidebar_content_panels = [ FieldPanel('sibling_checkbox'), ] but it's throwing this error: django.core.exceptions.FieldError: Unknown field(s) (sibling_checkbox) specified for MyPage My limited Django skills make me believe I'm close, but I'm not quite sure where to go from here. Can anyone help?
