Weird CSRF error in Django with Nginx and Gunicorn
Background When I try to access into my Django administration panel, I get Forbidden (403) CSRF verification failed. Request aborted., even if I disable the CSRF middleware. This affects all users, in different locations with different browsers. I've followed the steps to fix this error of several questions in stackoverflow, but still the same. This has been killing me for weeks. Issue I'm using https with Cloudflare (Free plan), but this error persist if I deactivate https. This occurs in mydomain.com/admin Known facts I'm using Django 2.0 and gunicorn 19.0 I've checked the cookies of my browser I've tried removing django.middleware.csrf.CsrfViewMiddleware This occurs just in the Django Admin dashboard, when CSRF middleware is enabled, the another POST or GET forms works fine. I'm logged into my Django Admin dashboard, and if I logout, I can login again with no problems, but if I try from another place, or with another user, the problem occurs again. Gunicorn config it's the default. Configuration files Settings.py CSRF_TRUSTED_ORIGINS = ['.domain.com'] CSRF_COOKIE_DOMAIN = ['.domain.com', '127.0.0.1'] CSRF_COOKIE_SECURE = True ALLOWED_HOSTS = ['127.0.0.1', 'domain.com', 'www.domain.com', '104.336.44.153', '.domain.com'] MIDDLEWARE = [ 'django.middleware.csrf.CsrfViewMiddleware', 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] Nginx server { server_name domain.com; access_log off; location … -
Embedding Bokeh Graph in Django using Ajax - It just outputs HTML text of the graph data
I have been searching for a while but there is not a good example out there really build upon. Right now I am trying to output stock data from an API and use Bokeh to graph the user selected option to display it. As I am still learning this, some help would be greatly appreciated. For starters this is how it works: The user selects from the dropdown what type of stock time frame he wants and types in whatever stock symbol he wants. "/dashboard/update" takes the data and processes the API request which gathers the JSON data and sends it off to the "/result" which sorts and processes the data. "/result" then outputs it on "results.html" using Bokeh. This is where my refactoring to use AJAX comes in. Due to not knowing how to embed bokeh with AJAX properly, I had used another example which apparently worked but managed to output the entire JSON into the HTML of the page. The error being shown says "Bokeh: ERROR: Unable to run BokehJS code because BokehJS library is missing\". I have inside my HTML placed the Bokeh CDN. Perhaps there is more needed? <script type="text/css" src="http://cdn.pydata.org/bokeh/release/bokeh-tables-0.13.0.min.css"></script> <script type="text/javascript" src="https://cdn.pydata.org/bokeh/release/bokeh-0.13.0.min.js"></script> This is … -
Django: while displaying list of articles show favourite status of each articles based on the user
I have List of articles to be displayed as per date. Every User can mark any article as his favourite. If a user is logged in, then he should be able to see some indication whether the article is already marked as his favourite or not. the following are my models: class Favourite(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE) date = models.DateTimeField(auto_now_add=True) article = models.ForeignKey(Article, null=True,on_delete=models.CASCADE) class Meta: unique_together = ('user', 'article') class Article(models.Model): title = models.CharField(max_length=256) intro_image = models.ImageField(null=True, blank=True, upload_to=doc_hash) description = models.TextField(null=True, blank=True) I was thinking for every article get all the user ids who marked that article as favourite and then later check it at front end with the current user. But if some article is marked as favourite by 1000 users , then unneccessarily i will have to get the data of 1000 users along with that article which is too much. Is there a way if i pass the user i can get the favourite data only with respect to that user for each article so that i can save both on queries and amount of data to be passed to front end. -

Downside of using non-ASCII language as source-code in django i18n?
Is there any downside, in terms of performance or difficulty, to use non-ASCII language as the source-language during an i18n? Specifically, will it be equal, performance-wise, to have: _("这是一条中文信息") translated by from Chinese to English rather than: _("this is an English message") translated by from English to Chinese? -

django form is not validating
So I have been trying to implement a way to post a project post in my website. However, it seems that there is something wrong with my validation with forms. Even if the form is correct and complete, it still wont validate. No posts are being made in my projects page and nothing gets added in my database.

Django CMS superuser login /logout by default logs-in / logs-out the site-user [respectively]
Use case: I have header htmls different for logged-in and logged-out customers.[ logged-in-header.html and logged-out-header.html] I am using django's user.is_authenticated to check whether user is logged-in or not and deciding my header html accordingly. This setup was working fine. Requirement: Now I wanted to bring logged-out header under django CMS as it contains / redirects to static pages. Given this, when i login the DJango-CMS portal , this user.is_authenticated is made true from django that for any cms page, i could only be able to see the logged-in header.This pushes me to the scenario where am not able to create placeholders for logged-out-header. Is it because request.user for Django-CMS app is intruding with request.user of my django app ? Or is it because of something else in django-cms ?

Can I create a custom decorator for a model method in Django?
Let's say I have the following model - class Banana(models.Model): name = models.CharField(max_length=255) def get_banana(self): return f'Banana: {self.name}' Now I want to add a logger that generates a log whenever the method starts and ends successfully to this get_banana method.

UpdateView gives KeyError with cleaned_data
I am creating objects in a model as shown below. What I want to be able to do is update the "class_list" with an UpdateView. The update seems to refer back to my object's modelform which has a clean routine in it, which causes a problem. class ClassroomForm(ModelForm): class Meta: model = Classroom fields = ['course_name', 'course_block','class_list'] def clean(self): try: Classroom.objects.get(course_block=self.cleaned_data['course_block']) self.redirect = True raise forms.ValidationError("Exists already") except Classroom.DoesNotExist: pass return self.cleaned_data I'm now implementing an UpdateView for this same model. The view is simple: class BlockUpdateView(UpdateView): model = Classroom fields = ['class_list'] success_url = reverse_lazy('classroom:blocklist') update_classroom_view = BlockUpdateView.as_view() This is called from the template code below: {% for block in classroom_blocks %} <li>{{ block.get_course_block_display }}<a href ="{% url 'classroom:blockUpdate' block.id %}" class="button">EDIT</a><a href ="{% url 'classroom:blockDelete' block.id %}" class="button">DELETE</a></li> {% empty %} <li>No classes set up yet.</li> {% endfor %} I successfully get to the view where I can update the model. After making my edit I press Submit and I get the following error: Exception Type: KeyError Exception Value: 'course_block' Exception Location: C:\Users\dwsmith\mysite\classroom\models.py in clean, line 59 line 59: Classroom.objects.get(course_block=self.cleaned_data['course_block']) I would like to know if and how I can use UpdateView in this situation.

Django Postman Import Error
I'm getting an import error on a model I created in the postman app in my django site. I duplicated a previous project because I want to store both on two different sites. The first project works flawlessly. Once I cloned into the second project, I'm getting an import error. I tried commenting the models and then uncommenting them, but that didn't work. The models are in the database and the same setup works on my first project. What could be causing this error on the second one?

My data insertion system in django does not work
I will explain my problem : I'm working on a commentary system, but I do not succeed at insert my datas in the table. I possesses an formulary based on my model in the file forms.py, then in my file views.py an function for treat the datas of my input textarea, then a html file with a field textarea, here is my code : models.py : class Commentary(models.Model): contents = models.CharField(max_length=500, null=True) created_at = models.DateTimeField(auto_now_add=True)) edited_at = models.DateTimeField(null=True) article = models.ForeignKey(Article, on_delete=models.CASCADE) author = models.ForeignKey(User, on_delete=models.CASCADE, null=True) forms.py : class CommentForm(forms.Form): contents = forms.CharField(widget=forms.Textarea, max_length=500, required=True) views.py : def createComment(request): if request.method == "POST": form = CommentForm(request.POST) if form.is_valid: commentary = form.save(commit=False) author = request.user commentary.contents = contents commentary.author = author commentary.created_at = timezone.now() commentary.save() return redirect('/home') read.html : <textarea name="contents" required id="contents"></textarea> I looked on the forum and in the documentation of Django, alas nothing is stock, my way is it good? Thanks all!
