is there a way to display a particular inline in a new page based on a condition?
I need to display only one inline in a new page based on the condition like if the url has the parameter country_id then i need to display only one inline. Since I cannot make it in one ModelAdmin since the model admin has form validations in it, I used two modelAdmins for the same model. I have a readonly field called get_countries in CorporateConfig(admin which has form validations) and it will display a list of countries. If i click on a country based on that country id i need to display CorporateBrand which is an inline model to CorporateConfig on a new page(remember only that inline needs to be displayed). class CorporateConfigurationAdmin(admin.ModelAdmin): form = CorporateConfigurationAdminForm inlines = [CorporateIncludeBrandAdmin, CorporateExcludeBrandAdmin, CorporateBrandsAdmin] def get_urls(self): from django.urls import path urls = super(CorporateConfigurationAdmin,self).get_urls() filter_url = [ path('filter_brand/',self.admin_site.admin_view(self.brand_filter), name='brand-filter'), ] return filter_url + urls def brand_filter(self, request, obj=None): pass def get_countries(self, instance): country_list = '<ul style="font-weight: bold;list-style-type:circle;">' countries = Country.objects.all() print("countries", countries) for country in countries: url = reverse_lazy('admin:brand-filter') print("urls is",url) country_list += '<li class="changelist"><a href="{url}?country_id={id}" target="_blank">{country}</a></li>'.format(url=url, country=country.name,id=country.id) country_list+='</ul>' return mark_safe(country_list) get_countries.short_description = 'Country Url' Clicking on the link above should go to the custom url which is created by get_urls() class BrandOrderFilter(CorporateConfiguration): class … -

Django + PostgreSQL: how to identify user contributions?

How to allow the user to change theme color for a bootstrap4 theme using a color picker in a django website?
I want to allow the application users to be able to change the bootstrap theme color using a color picker. I haven't found any good examples yet on how to achieve this in Django. I understand that adding predefined themes and toggling between them is simpler.

How to fetch warnings from a django mysql query?
I'm trying to get a list of warnings after a mySQL query, using Django admin. I can see from the documentation here that it's possible to record warnings by setting connection.get_warnings to true. But I can't find anything explaining how to read those warnings. I do not want to throw an exception - I am deleting items from the database using a DELETE IGNORE statement and want to get all instances of deletions that failed (due to external keys, etc.) I've tried returning the result of the execute function itself (just gave me a number) and calling fetchwarnings() on the cursor (threw a "Cursor object has no attribute fetchwarnings" error). I'm still new to both Python and Django. I'm looking through all the documentation I can find but can't find anything that works. from django.db import connection query = "{query here}" connection.get_warnings = True with connection.cursor() as cursor: cursor.execute(query) <-- Returns a number return cursor.fetchwarnings() <-- Throws an error -

Sanitizing SQL input in Django for PostgreSQL
I know that there are tools how to prevent sql injection especially with psycopg2 and how to work with them, but i have an other use case. The query should not be directly executed in PostgreSQL, but in InfluxDB as a part of join between metadata from PostgreSQL and measurements from InfluxDB that is done with the sql package from it. So i need to produce a string part of a bigger query that is totally safe, especially in the filter part of the query where a LIKE part is entered. I think this is possible by acquiring the the cursor object of the connection from the connection pool and then use mogrify() to get the safe sql after binding, but this approach seems complex and unnecessary as i don't need to execute it in PostgreSQL directly. Is there a tool or library in Python that can check/adapt/escape/sanitize the query as a string, or bind parameters in a safe way? -

I cannot understand why the result of my review form is not showing in the template, even though my ticket form is working fine. However, I have linked the 2 models with a foreign key. Then in the template I added "ticket.id". Finally, the objective of this app is to limit the review to one person. Thank you in advance for your help. My models: class Ticket(models.Model): title = models.CharField(max_length=128) content = models.TextField(max_length=2048, blank=True, null=True) image = models.ImageField(null=True, blank=True) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) date_created = models.DateTimeField(auto_now_add=True) def __str__(self) : return self.title class Review(models.Model): ticket = models.ForeignKey(Ticket, related_name="reviews" ,on_delete=models.CASCADE) rating = models.PositiveIntegerField(validators=[MinValueValidator(0),MaxValueValidator(5)]) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) headline = models.CharField(max_length=128) body = models.TextField(max_length=8192, blank=True, null=True) time_created = models.DateTimeField(auto_now_add=True) def __str__(self) : return self.ticket.title My forms : class TicketForm(forms.ModelForm): class Meta: model = models.Ticket fields = ['title', 'content','image'] class ReviewForm(forms.ModelForm): class Meta: model = models.Review fields = ['rating','headline','body'] My view : @login_required def review(request, ticket_id): ticket = get_object_or_404(models.Ticket, id=ticket_id) review_form = forms.ReviewForm(instance=ticket) if request.method == 'POST': review_form = forms.ReviewForm(request.POST, instance=ticket) if review_form.is_valid(): review = review_form.save(commit=False) review.user = request.user review.save() return redirect('home') return render(request, 'flux/create_review_post.html', context={'review_form': review_form}) My urls: path('home/', flux.views.home, name='home'), path('ticket/create/', flux.views.ticket, name='ticket_create'), path('flux/<int:ticket_id>/', flux.views.view_ticket, name='view_ticket'), path('<int:ticket_id>/review/create/', flux.views.review, name='review_create'), My template review … -
How to make media file's URL restricted to the unauthenticated users in Django?
I am going to build a Django storage application where users can upload files to the server. Users also can download their files from the server. To download the file, the server returns the URL of the media file to the user. I added a permission class, if the user is authenticated & owner of the file then return the URL of the media file, otherwise return 404. But there is a problem, if any unauthenticated user found the URL of the media file from the history of the browser, then he can download/access the file. How can I handle this case?
