The right way to declare choices for django-form
I wonder what's the best way to set choices for forms.ChoiceField in Django. I need a form which first will get the set of choices using SQL query (done with that) and then display it to the user. The problem with my solution is that I have the query in forms.py and it only updates once when I run the server. Any ideas how to make it update every time the form itself renders for the user? -

Django Models descending/nested query
I'm having trouble understanding how to use the table/model structure in Django to perform useful queries. What I'm trying to do is: given the primary key of a Show object, get a set of all the characters in the show. My models below: class Location(models.Model): identifier = models.CharField(max_length=200) def __str__(self): """String for representing the Model object.""" return self.identifier class Character(models.Model): identifier = models.CharField(max_length=200) def __str__(self): """String for representing the Model object.""" return self.identifier class Show(models.Model): name = models.CharField(max_length=200) shorthand = models.CharField(max_length=2, unique=True) def __str__(self): """String for representing the Model object.""" return self.shorthand class Season(models.Model): number = models.IntegerField() show = models.ForeignKey(Show, on_delete=models.SET_NULL, null=True, related_name="seasons") class Meta: unique_together = (("number", "show")) def __str__(self): """String for representing the Model object.""" return (str(self.show) + "s" + str(self.number)) class Episode(models.Model): number = models.IntegerField() season = models.ForeignKey(Season, on_delete=models.SET_NULL, null=True, related_name="episodes") class Meta: unique_together = (("number", "season")) def __str__(self): """String for representing the Model object.""" return (str(self.season) + "ep" + str(self.number)) class Scene(models.Model): number = models.IntegerField() character = models.ManyToManyField(Character, related_name="scenes") location = models.ForeignKey(Location, on_delete=models.SET_NULL, null=True, related_name="scenes") episode = models.ForeignKey(Episode, on_delete=models.SET_NULL, null=True, related_name="scenes") class Meta: unique_together = (("number", "episode")) def __str__(self): """String for representing the Model object.""" return (str(self.episode) + "sc" + str(self.number)) This seems basic enough, but … -
Django: Redirect to the referring page (not the current form) when an UpdateView fails validation and is then Canceled?
My Django application allows a user to navigate to an Update Form (UpdateView) from multiple locations in the application. Currently, if the form is saved successfully I can redirect without a problem to the referring page by saving request.META.HTTP_REFERER in a hidden field in the template and retrieving it in form_valid. I can leverage the HTTP_REFERER data in MOST, but not ALL cases. One of those is the following scenario: My user navigates to the FORM A from Page X (HTTP_REFERER is set to Page X) FORM A is submitted and does not pass validation (HTTP_REFERER is now set to FORM A instead of Page X because indeed it has self-refered.) My user clicks Cancel (they are redirected back to FORM A instead of Page X) Is there a way to capture the Cancel event before it is processed and perform some logic so my user gets referred back to Page X instead of being stuck in the form? -
How to link CSS to HTML file for Email Sending in a Django Project
I trying to figure out a way to link CSS to an email html for sending. I have used inlinecss but it didn't work out due to errors in locating the CSS file in static. My question is there any way to add CSS to my HTML email other than Inlinecss In my template I have used using Inlinecss: {% load inlinecss %} {% inlinecss "/css/bootstrap.css" %} TEXT {% endinlinecss %} Here is the complete path of the CSS file: C:\Users\User\Desktop\Project\static_in_env\css\bootstrap.css After debugging I found that the reason is due to [Errno 2] No such file or directory: 'C:\\Users\\User\\Desktop\\static_root\\css\\bootstrap.css' Here is the files structure: # Static files (CSS, JavaScript, Images) STATIC_URL = '/static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static_in_env')] VENV_PATH = os.path.dirname(BASE_DIR) STATIC_ROOT = os.path.join(VENV_PATH, 'static_root') MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') Any ideas to help link CSS to an email html for sending -
How can we add more than 3 authers field for a single article? in Django models
I created a magzine model in django. But their are more than three authors of a magzine. I have written below code for three authors. If I write the code of two or three author for a single magzine then it is looks somewhat good. But if I make for more than three authors then it will looks very bad. Now I am confused, Is the method that I have created is wrong? And if it is wrong then how should I write it? author_name1 = models.CharField(max_length=300, blank=True) designation1 = models.CharField(max_length=100, blank=True) author_pic1 = models.ImageField(upload_to="authorpic", blank=True) author_detail1 = models.TextField(max_length=1000, blank=true) author_name2 = models.CharField(max_length=300, blank=True) designation2 = models.CharField(max_length=100, blank=True) author_pic2 = models.ImageField(upload_to="authorpic", blank=True) author_detail2 = models.TextField(max_length=1000, blank=true) author_name3 = models.CharField(max_length=300, blank=True) designation3 = models.CharField(max_length=100, blank=True) author_pic3 = models.ImageField(upload_to="authorpic", blank=True) author_detail3 = models.TextField(max_length=1000, blank=true) -
How can i set pagination dynamically in Django Rest Framework?
I made an API endpoint using Django Rest Framework, it can be filtered according to two parameters. I'm trying to do the following: when there is no filter, it should retrieve x number of records, while when there is one or more filter, it needs to retrieve more records. So basically i need to change the pagination if there are filters. Here is what i tried: class My_View(viewsets.ModelViewSet): http_method_names = ['get'] serializer_class = My_Serializer pagination_class = StandardResultsSetPagination def get_queryset(self): valid_filters = { 'Name': 'Name', 'Date': 'Unix__gte', } filters = {valid_filters[key]: value for key, value in self.request.query_params.items() if key in valid_filters.keys()} if len(filters) == 0: pagination_class = StandardResultsSetPagination else: pagination_class = LargeResultsSetPagination queryset = My_Model.objects.filter(**filters) return queryset What this code what supposed to do is to set a standard pagination of 100 if there isn't a filter, and 200 if there are filters. This code doesn't work, the pagination will always be set to StandardResultsSetPagination, and it doesn't get changed. I think it's because get_queryset is called after the pagination is set, so it can't be set again later. Is there any way to do that? Thanks in advance! -

How can I host my Django website on a local server?
I have created a website with Django, running locally in a linux virtual machine on ip adress 192.168.0.111:8000. Now I want to make this website available for the public, hosted on my own machine. I have a webproxy (NginxProxyManager) running on my server on ip adress 192.168.0.118:7818 which handles all my other static websites. I can route my domain name https://django.example.com to 192.168.0.111:8000 in my webproxy and everything works in DEBUG = True, but i know this is not the way to do it, and DEBUG = False does not serve static files properly. How can i do this? All websites about this topic are takling about publishing to Heroku or something else, but i want to host it locally. Thank you! -
Django ".widget.attrs.update" with NO effect
I have a ModelForm with the following init method: def __init__(self, *args, **kwargs): super(FragebogenForm, self).__init__(*args, **kwargs) self.fields['birth_date'].widget.attrs.update({'type': 'date'}) This doesn't change the type attribute of the input tag, although it should according to the documentation (ctrl + f -> "Or if the field isn’t declared directly on the form"). If I change it to e.g. .widget.attrs.update({'placeholder': '12.12.1999'}) it works, the new placeholder appears on the page. Only setting the type to date does not work, but why? -

Creating a form instance in aview and then saving it gives a 500 Internal Server Error
This is my current view and because of using AJAX, the array sent to the view isn't in the right format so I'm using stringify to fix all of that. The problem is that I can't change the fields value on the existing form so I decided to create a new form. if request.method == 'POST': form = SubscriberForm(request.POST) category = json.loads(request.POST.get('category')) frequency = json.loads(request.POST.get('frequency')) formNew = SubscriberForm(form['email'], form['country'], category, frequency) This doesn't seem to work and I'm just getting a 500 Internal Server Error. -

Wagtail document re upload with the same name doesn't purge CloudFront
I'm using an S3 backend for Wagtail. When I upload a pdf with the name dummy.pdf and then reupload a different file with the same name, if the document was linked in a page then the page on the frontend of the site leads to the old link. I can get around this by uploading the file with a slightly different name or publishing the page with the linked document. Are there any solutions to this in Wagtail 2.10.1? Again I don't want to have to fork the framework. -
apache sites-enabled confusion
I see a ton of files in this sites-enabled folder in my /etc/httpd (I inherited this server). I believe it is acting like a firewall before passing off to other virtualhosts/servers. I want to make sure I understand what is going on. For instance, one website that lives on a different server has two files in the sites-enabled on this 'firewall server': site-abc-ssl.conf site-abc.conf Inside the site-techdb.conf I have: <VirtualHost *:80> ServerName techdb.abc.com ServerAlias techdb Redirect "/" "https://techdb.abc.com/" </VirtualHost> I believe this is forcing the request to SSL/HTTPS? So then in the site-techdb-ssl.conf I have (And this is what I am not sure what is going on, I am no guru in apache). <VirtualHost 110.104.19.17:443> ServerName techdb.abc.com ServerAlias techdb <If "%{HTTP_HOST} != 'techdb.abc.com'"> Redirect "/" "https://techdb.abc.com/" </If> ProxyRequests Off ProxyPass / http://mynewserver.abc.com:591/ ProxyPassReverse / http://mynewserver.abc.com:591/ <Proxy *> Order deny,allow Deny from all Allow from 110.104.19. 10. 153.16. </Proxy> Include extra/ssl-certs </VirtualHost> mynewserver is just an internal ip address to a machine that is actually defined in our DNS so the mynewserver.abc.com points to our 10.71.10.1 which is the new server I am trying to show on the web as techdb.abc.com This new server is running django (more than likely in … -
