Django project doesn't work when setting project root url to not "/"
I had a Django project (using Django, uwsgi and Nginx to deploy it) on a linux server that works well when I'm setting the project root url in Nginx as location / { uwsgi_pass django; include /path/to/project/uwsgi_params; } So the project can be accessed using url like: www.mysite.com However, I'm planing build more web projects on this server, and want to visit them using different urls like: www.mysite.com/oldproject www.mysite.com/project2``` So I changed my now existing project's Nginx conf file as: location /oldproject { uwsgi_pass django; include /path/to/project/uwsgi_params; } however, when I visit the old project using www.mysite.com/oldproject I get feed back like: Not Found. cant get resource on the server I'm pretty sure that the Nginx is working well with uwsgi because I did some simple test, so, what is going wrong?

Django admin action to copy queryset to another model
I have two models in a Django app. For ease, let's call them MainModel and DraftModel. These are similar (not same) models and former is more like a subset of the latter model, intentionally kept that way in order to keep the MainModel clean and verified for live. Once the admin manually verifies entries in DraftModel, is there a way we can have the admin select entries to be transitioned to MainModel, and click on an admin action like: def transition_selected(self, request, queryset): #do some updates queryset.update(status='TRANSITIONED') #get these entries duplicated to MainModel #WHAT SHOULD BE THE LOGIC HERE? transition_selected.short_description = "Transition selected into MainModel" -

My django_email_verification app is not working on my linux server
So I tested the code out on a localhost and it worked perfectly fine and I even received emails to verify accounts. Now when I git pulled and pushed to the server it keeps giving me a error every time I try to delete a user account or I do not get an email verification when I signup. I've checked my pip and the same libs are install but for some reason the linux server is giving me this error. How do I fix this? If there is any other code or errors you need please let me know and I will show you. -
DRF custom check_permission not being called
I'm trying to add a custom permission to a view which extends a generic DetailView: from django.views.generic import DetailView from rest_framework.permissions import BasePermission class MyCustomPermission(BasePermission): def has_permission(self, request, view): return False class MyView(SomeMixin, DetailView): model = MyObject template_name = "my_template.html" permission_classes = [MyCustomPermission] def get_object(self): return MyObject.objects.get(id=123) This should always fail, but it doesn't. I can also put a breakpoint in there (e.g. import pudb; pudb.set_trace()) but that won't ever get hit either. I know that has_object_permission(...) needs to be explicitely called, but I thought has_permission(...) got called when the view first got called. -
How to generate a drill down data from highcharts table?
I am new to front end development and using django to build a dashboard. I am leveraging high charts library for data visualization. I want to create a click event table with drill down data of point triggered. I want to send the click point details back to my views and trigger the view function (with view points as variables) to generate the table in a new page. Please suggest what functionalities can i use to achieve this? Is there any other way to achieve this? Eg. If user clicks on first bar, he should be directed to a new webpage which will have detailed tabular data fetched from database of Q1 2019. Check the jsfiddle example: https://jsfiddle.net/VM001/90jpvdw3/2/ point:{ events:{ click: function () { location.href ="clickTable"; alert('Category:'+this.category+',values:'+this.y) alert(this.options.name) } } } -

Django: How to go about loading multiple images from multiple objects on same render in html
I have been searching and came across this (Multiple images per Model) which explains how to get all the images for a specific object but how would I load multiple images for a list of 2,000+ objects - I know I could loop and grab all the objects from each image but then how would I display the correct images with the correct objects in the html? While writing this, I was wondering if this is a good use for template_tags but I am extremely new to them. Working with these basic cut down models as an example. class Auction(models.Model): auction_title = models.CharField(max_length=255, null=True) class Listing(models.Model): auction_id = models.ForeignKey(Auction, on_delete=models.CASCADE) title = models.CharField(max_length=255) class ListingImage(models.Model): listing_id = models.ForeignKey(Listing, on_delete=models.CASCADE, related_name='images') image = models.ImageField() view example to run off of, expecting anything up to thousands of items returned. listings = Listing.objects.filter(time_ending__gte=datetime.now()).order_by('time_starting') so with that example view above how would I go about grabbing each image for each of those listings and then more of an issue was finding the way to display those in html in loops or in any order or specifically chosen. Thank you so much for your help! -
