When launching django-app from herroku, it says "application error", but the logs doesn't show any error
I am working at a django app (noob) in PyCharm and back it up on GitHub. I want to run the app from heroku and I created an workspace and deployed the app from the Git link. In logs it says that the app is launching, but when I am trying to acces the page, it says "application error! An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details." This is the log: -----> Python app detected -----> Installing pip -----> Installing requirements with pip -----> $ python manage.py collectstatic --noinput 94 static files copied to '/tmp/build_92826bd11c22ebfaffc04da632fb123d/USR/static'. -----> Discovering process types Procfile declares types -> (none) -----> Compressing...

django aws ses boto3 - why different IAM credentials are used for verify_email_identity
I am trying to use django boto3 aws ses to to send email. I notice verify_email_identity uses a different IAM credentials, where is this set actually ? i didnt set it in my django app. client = boto3.client('ses', region_name='us-east-1') client.verify_email_identity(EmailAddress="bounce@example.com") -> IAM user B conn = mail.get_connection('django_amazon_ses.EmailBackend') -> IAM user A email = EmailMessage( 'Subject', 'Content', 'bounce@example.com', ['to@example.com'], headers={'From': 'from@example.com'}, ) self.assertGreater(conn.send_messages([email]), 0) -> IAM user A IAM user A has all the permission (like below), but IAM user B doesnt have. to me its strange why it is using IAM user B, how can that be possible ? i checked all my code there is no such settings for IAM user B { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "ses:SendEmail", "ses:SendRawEmail", "ses:VerifyEmailIdentity" ], "Resource": "*" } ] } In settings.py, this is IAM user A credentials, i didnt not set IAM user B in anywhere in the app, maybe somewhere else in the mac pc, but im not sure. AWS_ACCESS_KEY_ID = config('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = config('AWS_SECRET_ACCESS_KEY') The question is client = boto3.client and verify_email_identity sets the aws credentials -

Facebook redirection with Django and python-social-auth
To locally test the ability to login in my django app with Facebook through python-social-auth, I have followed these steps: define a mapping from 127.0.0.1 to www.florian.com in /etc/hosts add http://www.florian.com:8000/login/facebook and http://www.florian.com:8000/complete/facebook in the field OAuth valid URI redirect in Facebook Login --> settings run python manage.py runserver www.florian.com:8000 However, when accessing http://www.florian.com:8000/login/facebook, I get the following error: Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings. However when I check the validity of this URL with the field available in the Facebook Login --> settings, it is OK.

How to reset variable in image source?
My problem is that I can't figure out how to reset a part of <img src='' which is a value from AJAX. Every time a javascript function is called this ajax_value is added so I ran in to a problem that it keeps adding this value without removieng it first. Looks like this: Problem: /static/lpr_images/2018_04_14_08_00.png2018_04_14_08_01.png Situation: <img src="{% static 'lpr_images/' %}" + ajax_value /> Things I tried but they didn't work: $("#lcp_img").reset(); raises error Uncaught TypeError: $(...).reset is not a function Tried .remove() but that removes img tag. base.html ... <div class="modal-body"> {% csrf_token %} <img id="lcp_img" src="{% static 'lpr_images/' %}" alt="My image"/> {{ form.as_p }} <br> </div> .... <script type="text/javascript"> function get_task_info(data) { $.ajax({ ... document.getElementById('lcp_img').src += data.result.imageName; $("#exampleModal").modal('show'); }; function reset_img_src() { $('#lcp_img').reset(); }; </script> -
Wagtail | ChoiceField not displayed
I am facing some kind of incomprehensible behavior working with "StructBlock" and "ChoiceBlock". For some reasons the ChoiceBlock dont show up in admin-menu if designed via class-notation. Like that no choiceblock is shown at admin-menu. Only the textblock. class CodeBlock(blocks.StructBlock): code = blocks.TextBlock(required=True) type = blocks.ChoiceBlock(choices=[ ('markup', 'markup'), ('css', 'css') ], required=True), class Meta: template = 'home/blocks/code.html' class HomePageIndex(Page): body = StreamField([('code', CodeBlock())]) content_panels = Page.content_panels + [ StreamFieldPanel('body'), ] The following solution is in my opinion pretty much equal, but works well. I do not get why... Due the fact i need the Struct-Field more often i prefer the the class-notation. class HomePageIndex(Page): body = StreamField([ ('code', blocks.StructBlock([ ('code', blocks.TextBlock(required=True)), ('type', blocks.ChoiceBlock(choices=[ ('markup', 'markup'), ('css', 'css') ], template='home/blocks/code.html')) ]) content_panels = Page.content_panels + [ StreamFieldPanel('body'), Not get me wrong, i could make it work (using the bad-way). I wonder why that happens. Ty in advance -
TypeError: get() takes 2 positional arguments but 3 were given
I am trying to get an input to appear on my page, and have been following Max Goodridge's walkthrough ep.45, but seem to have gotten myself stuck on this particular section. If anyone could assist this would be a massive help. My urls.py: url(r'^bandlist/$', polls_views.bandlist, name='bandlist'), url(r'^bandlist/(\d+)/$', polls_views.BandView.as_view(), name='bandview'), My views.py def bandlist(request): query = Band.objects.order_by('bandname') args = {'query': query} return render(request, 'bandlist.html', args) class BandView(TemplateView): template_name = 'bandview.html' def get(self, request): form = BandForm() return render(request, self.template_name, {'form': form}) My forms.py class BandForm(forms.Form): post = forms.CharField() And the template (band.html) {% extends 'bbase.html' %} {% block content %} <h1>{{ band.bandname }}</h1> <h5>Total Ratings: {{ band.totalrating }}</h5> <h5>How many times have {{band.bandname}} been rated: {{ band.totalrated }}</h5> <h5>Average rating (Out of 5): </h5> <form method="post"> {{ form.as_p }} <input type="submit" value="Score" /> </form> {% endblock %} After this, I will then be attempting to implement a rating and review system for each band.

Django Rest Framework regroup queryset by a category
In the current project that i'm working on, i need to regroup (group) a queryset by category and put contents with same category in a list all provided together. I have the following model structure: class Category(models.Model): title = models.CharField(max_length=255) class Item(models.Model): title = models.CharField(max_length=255) category = category = models.ForeignKey(to="Category", verbose_name=_('category'), related_name='items', on_delete=models.SET_NULL, null=True, blank=True) I would like the output serialized result to be like: { "category_title_1":[ { "id": 1, "title" : "something", }, { "id": 2, "title": "something else", } ], "category_title_2": [ { "id": 3, "title": "another string", }, { "id": 4, "title": "and yet another title", } ] } I know i can always iterate over the queryset and group them manually, i'm wondering if there is a native efficient way to do this. Thanks -
Add local python module to the classpath in IntelliJ
I am trying to run/debug my python project from IntelliJ Ultimate 2018.1. I have defined a python SDK, a Django local server (as the project uses Django as a template language), the PYTHONPATH is properly defined, etc. If I execute python manage.py runserver from my MacOS terminal, the server starts normally.

When deploying Django into AWS Fargate how do you add the local ip into ALLOWED_HOSTS
I am testing out deploying my Django application into AWS's Fargate Service. Everything seems to run, but I am getting Health Check errors as the Application Load Balancer is sending requests to my Django application using the Local Ip of the host. This give me an Allowed Host error in the logs. Invalid HTTP_HOST header: '172.31.86.159:8000'. You may need to add '172.31.86.159' to ALLOWED_HOSTS I have tried getting the Local ip at task start up time and appending it to my ALLOWED_HOSTS, but this fails under Fargate: import requests EC2_PRIVATE_IP = None try: EC2_PRIVATE_IP = requests.get('http://169.254.169.254/latest/meta-data/local-ipv4', timeout = 0.01).text except requests.exceptions.RequestException: pass if EC2_PRIVATE_IP: ALLOWED_HOSTS.append(EC2_PRIVATE_IP) Is there a way to get the ENI IP Address so I can append it to ALLOWED_HOSTS? -
Django HttpResponse to raw Html
I want to start of by asking if what I'm doing is considered bad practice. I have a page where users can make comments. Once a user makes a comment, I want to reload the entire comment section using ajax and display it anew. My solution to this was to create a separate view that displays only the comments. Then, I can make web requests to this view, grab the response, and place the unaltered html response from it directly into my page. Is this a bad idea? What I've gotten stuck on is that there doesn't seem to be a way to get the direct html from an HttpResponse. I have a template that generates the page of only comments: {% for comment in comments %} {{ comment.text }} <br/> {% endfor %} And I display this response using {% autoescape off %}{{ comments_html.content }}{% endautoescape %} in the main template that has the comment section. However, my output has lots of extraneous things: b'\n COMMENT TEXT\n \n\n COMMENT TEXT\n \n\n COMMENT TEXT\n \n' Is there a way I can strip these values using only javascript? Should I even need to do that - why are they there in … -
Django serializers: What does is_valid actually do?

Is it checking that the data in the message matches the data in the user profile? I've never used serializers before and could use an explanation of it. Thanks -
Django not filtering with user object

When I return email string, it works fine and record is filtered as well. But on passing user object from view, it returns None. I even tried with passing .filter(note=note, user=user.pk) but it is also not working. Printing print(user) prints username and other fields are also accessible via user.email, user.pk, etc. -
Django - how to make efficient use of django-mptt using DRY
I have a django blog project and am making use of Django-MPTT. I have two parent categories for my blog, "Travelling" and "Programming". The user is presented with all "Travelling" posts when they hit the home page, and I want to start writing posts in my "Programming" section too, which accessed via a nav bar. I am keen to make this as DRY as possible, but am not sure on the best way. The relevant structure is : views.py def getPosts(request): latest_posts = Post.objects.all().order_by('-pub_date') Travelling = Category.objects.filter(name="Travelling") childCats = Category.objects.filter(parent=Travelling) context = { 'latest_posts':latest_posts, 'childCats':childCats, } return render(request, 'posts/getPosts.html', context) def getPost(request, parentSlug, catSlug, postSlug): parent = Category.objects.root_nodes() childCats = Category.objects.filter(parentSlug=parentSlug) childCat = childCats.get(catSlug=catSlug) post = Post.objects.get(postSlug=postSlug) try: nextPostSlug = post.get_next_by_pub_date().postSlug except: nextPostSlug = None try: previousPostSlug = post.get_previous_by_pub_date().postSlug except: previousPostSlug = None context = { 'parent':parent, 'childCat':childCat, 'childCats':childCats, 'post':post, 'nextPostSlug':nextPostSlug, 'previousPostSlug':previousPostSlug, } return render(request, 'posts/getPost.html', context) posts.urls.py urlpatterns = [ url(r'^$', views.getPosts, name='getPosts'), url(r'^(?P<parentSlug>[\w\-]+)/(?P<catSlug>[\w\-]+)/$', views.getCategory, name='getCategory'), url(r'^(?P<parentSlug>[\w\-]+)/(?P<catSlug>[\w\-]+)/(?P<postSlug>[\w\-]+)/$', views.getPost, name='getPost'), url(r'privacypolicy$', views.privacypolicy, name='privacypolicy'), ] getPosts.html ... {% for post in latest_posts %} {% if post.show_in_posts %} <a href="{% url 'getPost' parentSlug=post.category.parentSlug catSlug=post.category.catSlug postSlug=post.postSlug %}"> </a> ...

How to upload multiple images from a single "Choose Files" selector in django admin
I'm doing this little project simulating a clothing ordering system to brush up my django skills. I have to add several pictures of a certain item(not a fixed number). So, using a fixed number of image fields in Item model is not ideal. So, I thought of another model consisting only of images connected to the model 'items' by a key. Now I know that django has the inline option for adding model objects one by one as per requirement. But that seems a bit of a sucker as you have to open that dialog box and select the images one by one. Is it possible that there be a selector via which we could choose multiple files at once and they be added to the model?? -

Django, comments cannot get the name of the post they are on
I'm having an issue with Python Django. It has to do with foreign keys and models. I have been told before that my questions are often incredibly mediocre, so please bear with me on this. I am trying to configure comments for a social network I'm working on and I've just got comments working, kind of. The issue is that, although I can input a comment and the database will log it and the person who wrote it, it won't log the post it is on. It always returns null. This is really the full extent of what I can say, as I REALLY don't understand what is happening. Here are a number of different code snippets and image that should hopefully be able to elaborate on the issue without requiring my interjection. 1: The models of the post-app https://pastebin.com/XXNsCa5g The important model being: class Comment(models.Model): 2: The reply template: https://pastebin.com/GsLUQqYp 3: The reply view: class PostReplyView(CreateView): model = models.Comment template_name = 'post_reply.html' fields = ['comment'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) Finally, a visual representation of what is missing from a comment when it is posted: enter image description here -
django form pagination save in local storage

There are large number of pages so this is generic and I should not use field names to access field values, just this field objects. Would you please give me a pointer how to acheive this. Thanks -
Django "ValueError: Can't bulk create a multi-table inherited model"
Problem I am using the django-model-utils InheritanceManager.
