ModuleNotFound error in django. PS - virtualenv misbehaving
Something had been wrong with my virtualenv. I never shut pc down nor the text editor with terminal(vs code). I just deactivated vituralenv last night and activated it today to find it's name has changed. I wasn't able to runserver so I figured out something was wrong with virutalenv because on pip freeze it shows all the packages. I installed virtualenv again and made a virtualenv with same name in same directory which overwrote previous virtualenv and now it's fine. Although while executing python manage.py runserver, it shows.

Django: How to prevent form resubmission when form validation unsuccessful?
I have looked into this problem with possible duplication but it seems like mine's a different problem. So I have forms which use sessions to temporarily store data. I have also included {{ form.errors }} in my templates to display the errors upon validation. The problem is, when I try to reload the page () when form is invalid/unsuccessful and the errors were displayed, instead of just refreshing the page and clearing the fields as well as the displayed errors, a confirm form resubmission dialog appears and the errors in my form remained. How should I prevent this dialog from appearing? -

Django, static files, and horizontal scalabilty
I am making a website in Django, and I am trying my best to make sure it is horizontally scalable. Due to the application being horizontally scalable, I am unable to save Images that users upload locally, in the media folder. I was wondering what are some ways I could save the images that the users upload, in such a way that would allow my application to be horizontal scalable? I do have a MariaDB Galera Cluster that I use to store other data, but it seems like saving images in a shared database might not be the best idea due to performance reasons (Storing Images in DB - Yea or Nay?). If I attempt to use the media folder, are there any solutions that could sync storage (folder) between different instances of the application? In general, what are some good practices for serving(download/upload) static content like images for horizontally scalable websites, and does Django provide anything to assist with this matter out of the box? -

How to create a membership record for a new user with django_rest_auth and django rest framework
I'm trying to create an invite/acceptance workflow with Django Rest Framework and Django Rest Auth. I have my initial account creation working just fine. Then a user creates a team, no problem. That owner now sends invites. Cool. Email's go out and the invitee get's the email with an ID for the team that they are being invited to. Here's where I'm struggling. There is a membership model that connects a team and a member. When a user has been invited registers, I want to create that membership record. So, where do I put that membership creation method? Is it in the serializer or the view? Django Rest Auth RegistrationView calls the save method of the RegistrationSerializer here. The serializer returns the created user to the view for the response. I know I need to create the membership record AFTER the user is created otherwise there isn't a user to add to membership. But I can't figure out where to do this? I was thinking of creating a create_membership method that is fired after the create method is run, but that isn't working. Something like this: def create_membership(self): team = "6edb0a55-199a-4aae-aa40-e7313186136b" return Membership.objects.create(team__id=team, member=self.user) Then calling it like this (this … -

django template timeuntil timezone

The start time is rendered in local time correctly. But the timeuntil countdown is not in the localtime. Is there a good way to achieve the desired output? So far the best thing I can think of is to compute another datetime column with the client's timezone difference applied. Then the template could simply render {{ meeting.start_local|timeuntil }}. -
Programatically create Redirects in Wagtail
Is there a way to programatically create functioning Redirect objects in Wagtail? I am trying the obvious (naively creating the object): Redirect.objects.create(old_path='/test', redirect_link='https://stackoverflow.com') This creates a Redirect that is visible in the Wagtail admin panel, however navigating to /test simply 404s without redirecting. However, if I then save the Redirect from the admin panel, it suddenly works. Is there some special post-save logic I need to run in order to activate the redirect? I looked through the source and could not find anything. -
Pagination menu changing length
I'm paginating some data from a django model. My issue is that I don't know how to control the menu for the pages. I'd like it to show maybe 10 page links at a time and gradually move across. This works to a degree, as it moves forward it will show more, so if on page 1 it will show 1-10, if on page 2 it will show up to 11. The problem is I can't control this in a static fashion. I would like to show 1-10 and then once it gets to 6, display 2-11 and so on. it works from 6 onwards, the problem is at the beginning it will show 1-5, then 1-6, then 1-7 until it gets to 6 when it will look correct. I hope this makes sense.... Here's my html: {% if contacts.has_other_pages %} <ul class="pagination"> {% if contacts.has_previous %} <li class="page-item"> <a class="page-link" href="?page={{ contacts.previous_page_number }}">Previous</a> </li> {% else %} <li class="page-item disabled"> <a class="page-link" href="#">&laquo;</a> </li> {% endif %} {% if contacts.number|add:'-4' > 1 %} <li class="page-item"> <a href="?page={{ page_obj.number|add:'-5' }}">&hellip;</a> </li> {% endif %} {% for i in contacts.paginator.page_range %} {% if contacts.number == i %} <li class="page-item active"> <a … -

Nginx takes too long to send the network response using Django with Gunicorn
I'm developing a web application with Django, and so far everything seems ok, but I'm having a big problem with my server response, usually the first time I want to enter it takes around 20 to 40 seconds to get the response back from the server. I'm using a Linode linux virtual machine running Ubuntu 18.04, is a very cheap plan just for now with only one core CPU, 2GB of ram and 50Gb of SSD storage, however as I'm the only one accessing the website I feel it is not correct that it takes so long to response (It just happen every time I restart nginx or gunicorn, or after some time of inactivity, after it respond it start to work with a normal speed). I made a performance record with chrome dev tools and these were my results: Network result As you can see the network request took 22 seconds, and if I check the main thread I can see that chrome detects that time as idle, and the real time it takes the server to process the view is only a few milliseconds.

Currently I have a ForeignKey relation from the attribute to the product and the attribute_category. class Attribute(models.Model): product = models.ForeignKey('Product', on_delete=models.CASCADE, related_name='products') attribute_category = models.ForeignKey('AttributeCategory', on_delete=models.CASCADE, related_name='attributes') And some more data... And at last the attribute_category. class AttributeCategory(models.Model): name_single = models.CharField(max_length=30, unique=True) Yet more things... I was thinking with this structure I can filter the objects for a specific attribute- or _category. Though now I am stuck, Is there any way I can go from the product, to the category of its attributes and then get the relevant attributes. This way I can structure my response like this: product1: [ {attribute_category1: [{attribute1}, {attribute2}] }, {attribute_category2: [{attribute3}] } ] I would like to know, how can I get the desired JSON. Am I missing something? Because it feels like I am grossly overcomplicating things. I realize that this question is incredibly messy and might be worded really bad. I will try to think up some way of making the problem worded better, if anyone has any tips on the problem, or rewording it … -
GeoDjango display map on template form from model
I am trying to build a sample website based on Django(GeoDjango) and OpenStreetMap. So far I have this simple scenario: Models.py class Parks(models.Model): park_name_en = models.CharField(max_length=256) description = models.TextField() picture = models.ImageField() geom = PolygonField() @property def picture_url(self): return self.picture.url def __unicode__(self): return self.title views.py def park_insert(request): form = ParkForm() return render(request, 'addpark.html', {'form': form}) forms.py class ParkForm(forms.ModelForm): class Meta: model = Parks fields = ('park_name_en', 'description', 'picture',) geom = forms.PolygonField() and last but not least the template addpark.html <html> <head> {{ form.media }} </head> <body> <div id="map"> <form enctype="multipart/form-data" method="post" action=""> {% csrf_token %} {{ form.as_p }} <input type="submit" value="Submit"/> </form> </div> </body></html> When I open the template page all fields come up right, except the PolygonField() which comes up as a text. How can I display a map on the user form also (I got it working in the admin panel, but I want to create a form for inserting new parks) -
