Django - Multi Tenancy vs Sites Framework, When to use each?
I'm designing an API that handles multiple domains by country (e.g peru.website.com, chile.website.com, etc.). I read about two aproaches: using django sites framework or django multi tenancy, but I am not sure about the advantages of each one. When should I use one over the other? -

Django admin ignores dynamically generated form fields
I'm trying to have the django admin display a model form with dynamically generated fields. I setup my form like this: class EulogyTextForm(f.ModelForm): class Meta: model = EulogyText fields = '__all__' def __init__(self, *args, **kwargs): super(EulogyTextForm, self).__init__(*args, **kwargs) for i in range(len(settings.MULTITEXT_LANGUAGES)): field_name = 'language%s' % (i, ) self.base_fields[field_name] = f.CharField(disabled=True, initial=settings.MULTITEXT_CHOICES[i][0]) field_name += '_text' self.base_fields[field_name] = f.CharField() I have setup my admin like this: class EulogyTextAdmin(admin.ModelAdmin): model = EulogyText exclude = [] form = EulogyTextForm However, Django admin will not display my added fields. I have created a TestView to display the form. In the test view, the form is correctly displayed with the added fields. Why does Djang admin ignore the additional fields? -

Django - Multi Tenancy vs Sites Framework
I'm using django and django rest framework to create a website. One of the requirements is that the website must be multi domain, by country (e.g. peru.website.com, chile.website.com, etc). I read about 2 ways to achieve this goal: The site framework: A model that stores the domain names that relates to other models via foreign keys. Django multi tenancy package: Separate domains by DB schemas. What would I need? I think would I need the site framework because certain models must be common across sites, like the user model. There should be only one superuser and the user's email must be unique for all domains. But I'm not sure whether I can do more than that with the site framework or it is its only advantage. So, the question is: what would be the advantages of using one instead the other? I would really appreciate if anyone could tell me a detailed comparison between both aproaches. Thank you in advance. -
POST fails without executing even a single line
I'm trying to POST from a website with different origin. I use JavaScript to call the API. A minimal example of what I've done is shown: JavaScript: options = {method: 'POST', // mode: 'no-cors', headers: { 'Content-Type': 'application/json' }, body: formData } fetch(url, options).then(response => { console.log(response) }).catch(err => { console.error(err) }); } Django Rest Framework based class: class ImageUpload(APIView): def post(self, request, format=None): print("data:", request.data) print("file:", request.FILES) response = Response(status=status.HTTP_201_CREATED) response['Access-Control-Allow-Origin'] = "*" response["Access-Control-Allow-Headers"] = "*" print(response) return response def options(self, request, *args, **kwargs): response = Response() response['Access-Control-Allow-Origin'] = "*" response["Access-Control-Allow-Headers"] = "*" print(response) return response With this example, I get CORS error that Cross-Origin Request is Blocked. This is due to the missing header. Interestingly, upon calling the API, my django console doesn't print a single line which it was supposed to upon calling the POST request. How did DRF send a response without going into def post? Before calling POST, OPTIONS is called which behaves perfectly as it should have. I even got the response printed on console. Also, another observation is, the API works perfectly fine when i uncomment mode: 'no-cors'. Upon researching, I found that I can use django-cors-headers, but opening up CORS to all … -

How can i update with modelformset_factory on Django

But when I want to update the post, I don't know how to do this, I tried something, but this only serves to re-upload photos and upload the uploaded photos again. How can I update or delete a previously uploaded photo? Also, I cannot access the photos in formset as {{formset.image}}. How can I access this?

Python Django Form submit button not working as desired
I have been trying to learn Django. I am stuck on this form part. A form has been created that allows the user to create an Album object where they can fill in the Artist, Album Name, Genre and upload an Album Logo. When I fill in the fields and then click submit, it should then redirect me to the details page for that particular Album that just got created. But nothing appears to happen when clicking the submit button and the object does not get created.

I have not used crispy_forms as I am not familiar with Bootstrap though I know CSS. {% extends 'music/base.html' %} {% block title %}Add …
