CSRF protection to a view with a download api request
I have this view in my application that calls an api to download a pdf: @login_required def generateContractPdf(request): file_id = request.POST.get('contract') contract_id = request.POST.get('contract') payload = {"file_id": file_id} data = {"data": json.dumps(payload, default=str)} headers = {'content-type': 'application/json'} brokkr = os.environ.get("BROKKR_ADDRESS", default='localhost') response = requests.post('http://'+brokkr+':5000/contract', params=data, headers=headers) filename=str(contract_id)+".pdf" response = HttpResponse(response.content, content_type='application/pdf') response['Content-Disposition'] = 'attachment; filename="'+filename+'"' return response But I just realiced that if I dont use render() the csrf doens't work, so this view could be exploited. How can i transforme it to keep that protection? -

When do you need to use iri_to_uri after using url_has_allowed_host_and_scheme in Django?
In the Django 3.0 release notes, this comment is made about url_has_allowed_host_and_scheme: To avoid possible confusion as to effective scope, the private internal utility is_safe_url() is renamed to url_has_allowed_host_and_scheme(). That a URL has an allowed host and scheme doesn’t in general imply that it’s “safe”. It may still be quoted incorrectly, for example. Ensure to also use iri_to_uri() on the path component of untrusted URLs. I understand what the purpose of url_has_allowed_host_and_scheme is. Take the common use-case of providing a next query parameter, for example: http://example.com/foobar?next=http%3A%2F%2Fexample2.com%2Fhello . You could program the view that handles this path to redirect to the URL provided by the next parameter, in this case: http://example2.com/hello . If the URL is not validated, then this is an "open redirect" vulnerability. Malicious actors could take advantage of an open redirect to hide malicious URLs behind a URL that looks trustworthy. You can use url_has_allowed_host_and_scheme to ensure that the URL has the expected hostnames and scheme. My question is concerning iri_to_uri. The documentation implies that you also need to use this function as well. When would I need to use it? -
How to prevent your free tier heroku app from idling(python/django)
Is there any way, through code, to prevent your app from idling? I'm thinking something like what is being done here. How to do this through code, but in python/django as that is what my app is done in, i.e. what is the equivalent in python to Node's setInterval. What are the disadvantages of using a pinging service over doing it through code(other than if the site goes down your app wont get pinged). Can you recommend a good pinging service? Thanks in advance. -

How to limit the inline ForeignKey queryset to the instance itself in Django admin
I have 5 models and their relations are as follows: class A(models.Model): pass class B(models.Model): a = models.ForeignKey(A) class C(models.Model): b = models.ManyToManyField(B) class D(models.Model): pass class I(models.Model): a = models.ForeignKey(A) b = models.ForeignKey(B) c = models.ForeignKey(C) d = models.ForeignKey(D) I decide to use the django admin class IAdminInline(admin.TabularInline): pass class DAdmin(admin.ModelAdmin): inlines = [IAdminInline, ] The admin page makes a lot queries,if too many I instances are related to D, which is time consuming. So I disable the Django default actions by setting the formfield_for_foreignkey: def formfield_for_foreignkey(self, db_field, request, **kwargs): field = super().formfield_for_foreignkey(db_field, request, **kwargs) field.choices = [] # django will not make any queries if set choices Instead, I use ajax to get the corresponding data, and use javascript to render the select widgets and bind actions , which make it easier to add data since these widgets are related to each other. Page loads faster but problem is that, the above code would clear I instances initial values that are apparently already existing in the change view page. I want to ask how can I render the existing inline object select widgets to their own values? I haven't find any solutions yet... -

DRY validation of query params for djangorestframework view
I want to create a view in django-rest-framework. This view would accept several custom query parameters, so it wouldn’t be based on any existing view. I want the query parameters to be available in the OpenAPI 3 schema for the purpose of type-checking in the TypeScript client. My questions are: How can I perform the validation of these parameters declaratively? Is using Serializer a good way to perform validation of a query string? How can I generate the corresponding part of the OpenAPI 3 schema in a DRY way? I see that the existing drf views don’t use a DRY pattern here (they just return a static directory for schema). Also, the method that generates schema for Serializers is underscore-prefixed, so it might not be a good idea to use it directly (although I don’t know the rationale for this). So what are my options here? -
Alternative for drf-expander

Django how to map LDAP group to django grup and automatically assign to user
I am wondering if there is possibility to map LDAP group with Django group and assign it automatically to user from LDAP group, OR if there is at least possibility that every new user logged and authenticated on via LDAP can be assign by default to specific group? I have 3 groups created via admin django page: ADMIN ENGINEER READER and i have 3 groups in LDAP: DSAPB2T_PASSED_ADMIN GSAFU3T_PASSED_ENGINEER GSAFU3T_PASSED_READER is there any possibility that when user from GSAFU3T_PASSED_ENGINEER group log in for the first time, will automatically be assign to ENGINEER django group? (same for ADMIN and READER) or if this is not possible or good solution, is there a possibility that every new user (authenticated form any of these 3 LDAP groups) will be automatically assigned to READER group? -
Django Writable fields and serializers error with foreign keys
Not sure what's going on here, but I can't seem to POST as expected. Here's the error I get: TypeError: Got a `TypeError` when calling `Upload.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `Upload.objects.create()`. You may need to make the field read-only, or override the UploadSerializer.create() method to handle this correctly. My models.py: class Project(SoftDeletableModel, TimeStampedModel): id = models.AutoField(primary_key=True) name = models.CharField(max_length=511, blank=True) def __str__(self): return str(self.id) class Upload(TimeStampedModel): id = models.AutoField(primary_key=True) file = models.FileField(upload_to=random_filename("uploads-%Y%m%d")) upload_type = models.CharField(choices=AVAILABLE_UPLOAD_TYPES, max_length=127) project = models.ForeignKey(Project, on_delete=models.PROTECT, related_name="uploads") def __str__(self): return str(self.id) serializers.py: class UploadSerializer(serializers.ModelSerializer): class Meta: model = models.Upload # fields = ("file", "upload_type", "project") fields = "__all__" class ProjectSerializer(serializers.ModelSerializer): uploads = UploadSerializer(many=True, read_only=True) class Meta: model = models.Project # fields = "uploads" fields = "__all__" viewsets: class UploadViews(viewsets.ModelViewSet): serializer_class = UploadSerializer queryset = Upload.objects.all() class ProjectViews(viewsets.ModelViewSet): serializer_class = ProjectSerializer queryset = Project.objects.all() I can create projects as expected, but when I try to create uploads, I get the error as described before. Does this have to do with the foreign key? I'm confused what is/isn't writable here. I'm doing this through the django web UI -

Intellj python test running Django environment separately
I have Django application inside IntelliJ IDE. I can run all Django tests by calling the Django Tests runner. But: This is a time consuming and not ideal for development, where you would like to rerun one test that fail, and not run all 1000 others that are ok. IntelliJ has options (UI) to run one test quickly, but this run python tests runner. I add DJANGO_SETTINGS_MODULE=... inside, but now I get other errors: django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. I was looking to solve this error and I only found : import django django.setup() inside Settings.py My problem with this is: I think this breaks normal behaviour of the app. App works normal for different environments. It doesn't call code after this setup inside settings, so secret_key and others are not installed This doesn't seam to be really related to tests, but is changing the whole app. So, I am looking for some settings, how to set the normal python tests, so that they will run as django tests. -

Here I want to display form validation error message with the help of ajax.For this I tried like this but there are some problems with this code. Here It displays the error message if not group is unique which is fine(works as I wanted) but I want to disappear this message after the user clears the name from input field(which is not happening now.) and if the user writes the unique group name I want to display some other message like "Ok" or something else. How can I do it ? def validate_group_name(request): group = request.GET.get('name') data = {'is_taken': Group.objects.filter(name__iexact=group).exists()} return JsonResponse(data) ajax <script> $("#id_group").change(function () { var form = $(this).closest("form"); $.ajax({ url: form.attr("data-validate-group-url"), data: form.serialize(), dataType: 'json', success: function (data) { if (data.is_taken) { $(".error").text("This group name already exists").show(); } } }); }); </script>
