django-tenats for django rest framework. How to manage SasS app
I am thinking about using django-tenants for my SaaS application. I ran some tests and all looks great, I can see data isolation on postgres schemas. The problem now is how to delivery it to customers ? I mean, I wanted a web ecommerce application where user can buy this digital product ( SaaS ) and access it. The problems I am facing are: 1- URL of each tenant is going to be different. And I don't want the user to have to type something like tenant1.example.com / tenant2.example.com . I want the same URL. 2- I am going to use rest framework because there's going to be also a mobile app for each tenant. So how the mobile will know each tenant URL to authenticate using the rest api ? Thank you -

pass URL parameter into form input without it reseting after form post
I have a tour page that links to a booking page and I've set it up so it sends the tour number as a URL parameter 'tour' to the booking page. I then want to display the tour title on the page and add the URL parameter into the booking form which will then email me with the participant details and the tour number. However the form input value 'number' gets reset when I POST the form. How do I make sure 'number' does not reset? Currently, I just get a None value for 'number' when I POST the form. tourpage.html <div class="text-center"> <a href="/booking/?tour=1" class="btn btn-primary text-center fs-2">Book This Tour Now</a> </div> booking.html <p class="fs-3">Booking: {{title}}</p> <main> <div class="col-12"> <form class='contact-form' method='POST' action='/booking/'> {% csrf_token %} <input type="hidden" id="g-recaptcha-response" name="g-recaptcha-response"> <input type="hidden" id="number" value={{tournumber}}> <div class="row g-3"> {% for field in form %} {% if forloop.last %} <div class="col-12"> {{ field.label_tag }} {{ field }} {% else %} <div class="col-sm-6"> {{ field.label_tag }} {{ field }} {% endif %} </div> {% endfor %} <button class="w-100 btn btn-primary btn-lg" type="submit">Submit</button> </form> </div> <p>Alternatively you can always reach us on <img src="{% static 'email_image.png' %}" width="300" height="22"></p> </div> </main> <script> //global … -

Django different types of users like teachers and students
I am building an application where the teacher can access forms and add marks of the students where as, the student should only be able to view their marks and result and not be able to update anything..

How to create my own custom login form for the students? If anyone can link some source or docs that will be useful.. Also, if someone can give an idea of how to get started, it would be great. -
Publish a custom Django Flatpage at a set date and time
I have a custom Flatpage model: from django.contrib.flatpages.models import FlatPage class MyFlatPage(FlatPage): publish = models.DateTimeField() so that I can add a publish date in the future. Now, I don't have a proper list of flatpages on the front end, my use for frontpages is more like 'one-offs', where I specific the URL and all that. For example, 'about', '2019prize', 'Today's walk', stuff like that. How can I set these pages I create to be displayed only after the publish date has arrived? I know that I can filter them by looking up something like pages.(Q(publish__lte=now)). Where and how should I put that code though? -

If page is unpublished go to the next available page
I'm creating a webcomic using Django. I have a status choice field in my model: 1 to publish a page and 0 to unpublish it. STATUS = ( (0,"Draft"), (1,"Publish")) I have created two functions: the first one to go to the previous page and the second one to go to the next page. def get_previous(self): previous = Page.objects.filter(status=1).get(number=self.number - 1) if previous.number > 0: return reverse('comic_page', args=[previous.chapter.slug, previous.number]) return None def get_next(self): last = Page.objects.filter(status=1).last() next = Page.objects.filter(status=1).get(number=self.number + 1) if next.number <= last.number: return reverse('comic_page', args=[next.chapter.slug, next.number]) return None It works as expected when all the pages are published, but when one of the pages is unpublished it doesn't go to the next available page but just refreshes the page. I tried creating another queryset with only unpublished pages and then checking if the page exists in that queryset and jumping 2 page numbers instead of 1 but it did not work. def get_previous(self): previous = Page.objects.filter(status=1).get(number=self.number - 1) unpublished = Page.objects.filter(status=0) if previous in unpublished: previous = Page.objects.filter(status=1).get(number=self.number - 2) return reverse('comic_page', args=[previous.chapter.slug, previous.number]) if previous.number > 0: return reverse('comic_page', args=[previous.chapter.slug, previous.number]) return None Any suggestions are appreciated, thank you! -
Change the extra field data in Many-to-many relationship in Django
I have a Many-to-many relationship with additional fields and I want to be able to change data in these fields (e.g. the status of friendship). How can I do that? All the info I found is about how to just read these data. class Profile(models.Model): # other fields friends = models.ManyToManyField("self", blank=True, through='Friendship', through_fields=('user', 'friend'), symmetrical=False, related_name='user_friends') class Friendship(models.Model): user = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name='friendships1') friend = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name='friendships2') status = models.PositiveSmallIntegerField(default=0) class Meta: unique_together = [['user', 'friend']] I tried this and that didn't work, though no error was shown: user = User.objects.get(username=request.user) watched_user = User.objects.get(id=watched_user_id) Friendship.objects.filter(user=user.profile, friend=watched_user.profile).status = 5 user.save() I can't call Friendship.save() as it has no self. And also I tried this and again no effect and no error: user.profile.friends.set([watched_user.profile], through_defaults={'status': 5}) user.save() And this gives me an error that there's no friend field and shows me the fields of Profile, not Friendship: user.profile.user_friends.get(user=user.profile, friend=watched_user.profile).status=5 Please help me! -

Append header in a vue axios request
I have a django backend and a Vue 3 frontend. For handling some request, my backend needs an 'Id-Client' header in the headers of the request. Developing my BE everything worked like a charm, but now that I'm writing the FE I'm encountering some issues. As I said before, I need to append and header to my headers in every request. So the first step was the following: // Note that the idClient is dynamic and can change. this.$axios.setHeader('Id-Client', idClient) const data = await this.$axios.$get(url) But I can't get it to work, if I try to send that request, my get request becomes (I don't know why) a OPTIONS request and I get the error "cross origin resource sharing error: HeaderDisallowedByPreflightResponse" Instead if I remove the set header // this.$axios.setHeader('Id-Client', idClient) const data = await this.$axios.$get(url) The server just respond me correctly giving me the error that the request is missing the 'Id-Client' in the header. I also have a few request that don't need the 'Id-client' header and those request work, so I don't think is a CORS problem. -
set a global setting during django startup
The figure shows my django structure. I don't have a django app according to django glossary. When django starts, I want to load a system configuration, for instance query the value of DSHELL in /etc/adduser.conf, then save it to a place where view.py can access. How would I implement it? I tried the following options: I looked at Django settings, but it discourages altering values in settings.py at runtime. From what I understand, Django Applications is saying I need to have a django app in order to use AppConfig.ready() which sets something global settings. Unless my folder structure is very wrong, I don't want to change it or switch to a django app. I'm using django 3.1 on Linux. -
