Django Authentication Form not authenticating and redirecting
After I put the correct password, it should redirect to "/articles" , BUT IT'S REFRESHING THE LOGIN PAGE ONLY. def login(request): if request.method == 'POST': form = a_form(data=request.POST) if form.is_valid(): return redirect('/articles') else: form = a_form() context = {'form': form} return render(request, 'accounts/login.html', context) This is what my html looks like: {% extends 'articles/base.html' %} {% block content %} <div class="container"> <form class="login" action="{%url 'login'%}"> {%csrf_token%} {{form}} <input type="submit" value="login"> </form> </div> {% endblock %} I wonder what is that I'm missing here. -

How to pass a value to a search query
I am working with two pages and I would like to click on a tag on one page, which would insert a value to a search query on another page.

Django selecting top n records per group using ORM
Following this question, I'm trying to get top 10 records per each group_by critera, but Django return this error: from django.db.models import F, Window from django.db.models.functions import RowNumber Purchases.objects.annotate(row_number=Window( expression=RowNumber(), partition_by=F('customer'), order_by=F('field_of_interest').desc() ) ).filter(row_number=10) raise NotSupportedError( django.db.utils.NotSupportedError: Window is disallowed in the filter clause.

Build a Django elegant filter with dynamic number of fields
I have a Django model which I'm doing a view for it, which filters results. models.py: Ingredient(models.Model): account = models.ForeignKey(Account, on_delete=models.CASCADE, null=False) brand = models.ForeignKey(Brand, on_delete=models.CASCADE, null=False) name = models.CharField(max_length=100, null=False, blank=False) cost = models.DecimalField(max_digits=14, decimal_places=2, null=False) Now the point is that the search form (which has every field except account of course), none of its fields are required, you can filter either for just a single field or two or the three of them. The problem is that I can't do: Ingredient.objects.filter(account=account, brand=brand, name=name, cost=cost) ...because brand, name, and cost could be sent empty/null How can I resolve this without making a filter line code for each filtering possibility? -
Django how to download a document that was inputted in a form
django 3.0 python 3.8 Here's a slightly odd question. How do you immediately download a document that was been uploaded. It may seem silly, but I'm trying to do it and can't seem to. Most of the things I'm looking at it want you to download a file that is saved somewhere, but the trick in my instances is that the file has never been saved (and shoudln't be). It's completely in memory. I want to give the downloaded for the same name as the inputted form. I currently download a file, but it is empty and has an odd name. So far I have this: Views.py class UpandDownloadFileView(TemplateView): form_class = UpandDownloadFileForm def post(self,request,*args,**kwargs): print('hi we posting files') print(self.request.POST) print(self.request.FILES) response = HttpResponse() response.write(self.request.FILES) response['Content-Disposition'] = 'attachment; filename={0}'.format(str(self.request.FILES)) return response forms.py class PopulateDocumentCreateForm(forms.Form): pass html <form method="post" action="{% url 'inputs:create' %}" enctype="multipart/form-data">{% csrf_token %} <div class='row'> <div class='col'> <p><input name="file" id="id_file" type="file"></p> </div> </div> <div class='row'> <div class='col'> <button class="btn btn-primary" type="submit">Submit</button> </div> </div> </form> (validation to come later) -

UpdateView creating new object instead of altering original
I will start this with I know this has been asked but I looked through those answers and not of them were the solution here. views.py: class JobUpdateView(UpdateView): model = Job form_class = JobForm template_name = 'job/edit_job.html' urls.py: path('edit/<int:pk>/', job_views.JobUpdateView.as_view(), name='edit_job'), template (included the <form> I use to delete objects just in case that was having some effect): {% for job in jobs %} <button ><a href="{% url 'edit_job' job.id %}" >Edit</a></button> <!-- edit--> <form class="" action="{% url 'delete_job' pk=job.id %}" method="post"> <!--delete--> {% csrf_token %} <input type ='hidden' name ='job_id' value='{{ job.id }}'/> <button type="submit">Delete</button> </form> </div> {% endfor %} This will display a list of the user's posts, if the users clicks 'edit' on a specific post it will display the proper object and its contents in a form to be edited. But, when the user saves that form, instead of editing the original object there are now two objects, the original and whatever was changed. Not sure why this happening? -
How to display Django input data on second page

Django How to combine different contexts and pass it to template

Unable to serve my Django site on port 80
I have successfully hosted my Django website on xyz.com:8000 which runs behind nginx & gunicorn. Currently my config file at /etc/nginx/sites-available/xyz.com looks like :- server { listen 8000; server_name 0.0.0.0; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/ubuntu/myproject; } location / { include proxy_params; proxy_pass http://unix:/home/ubuntu/myproject/myproject.sock; } } I am able to access my website at xyz.com:8000 using this. Now I want to show my website at xyz.com (right now it shows "welcome to nginx" page). So I modified above file and replaced line 2 with "listen 80". Then proceeded usual steps, of creating a symlink which produces another config file in /etc/nginx/sites-enabled/xyz.com But when I visit xyz.com, it is still showing me default "welcome to nginx" page! I tried changing "/etc/nginx/sites-enabled/default" and replaced 80 with 8000 everywhere, so now at xyz.com:8000 it shows default "welcome to nginx" page. But at xyz.com I am being shown 502 bad gateway. I searched over net but nothing seems to fix my situation, I have spent whole day trying them out. I am hosting on Google cloud, ubuntu. -
Is there a way to use Chart.js on Django without using API like rest?
I'm creating a project that has IoT on it, some arduino sensors etc. And I'm going to use MQTT not HTTP to transfer data from IoT to my web, after I transferred the data from the IoT, I need to graph it using Chart.js but on tutorials I found about chart.js they're using API to get Json Format to display it on graph.
