API view is empty when Filtering django rest framework view by PK in urls.py
I am trying to filter my APIListView by a PK value specified in the url. The code runs however my API is empty even though i know it has data at the PKs that i am testing. Any Ideas?

Django Categories and Breadcrumbs Issues
Everything works normally on the admin side. However, I could not show the categories and breadcrumbs on front site. I'd appreciate it if you could help me. models.py from django.db import models from mptt.models import MPTTModel, TreeForeignKey class Post(models.Model): title = models.CharField(max_length=120) category = TreeForeignKey('Category',null=True,blank=True) content = models.TextField('Content') slug = models.SlugField() def __str__(self): return self.title class Category(MPTTModel): name = models.CharField(max_length=50, unique=True) parent = TreeForeignKey('self', null=True, blank=True, related_name='children', db_index=True) slug = models.SlugField() class MPTTMeta: order_insertion_by = ['name'] class Meta: unique_together = (('parent', 'slug',)) verbose_name_plural = 'categories' def get_slug_list(self): try: ancestors = self.get_ancestors(include_self=True) except: ancestors = [] else: ancestors = [ i.slug for i in ancestors] slugs = [] for i in range(len(ancestors)): slugs.append('/'.join(ancestors[:i+1])) return slugs def __str__(self): return self.name admin.py from mptt.admin import MPTTModelAdmin admin.site.register(Post,PostAdmin) admin.site.register(Category, DraggableMPTTAdmin) settings.py MPTT_ADMIN_LEVEL_INDENT = 20 #you can replace 20 with some other number urls.py path('category/<path:hierarchy>.+', views.show_category, name='category'), views.py def show_category(request,hierarchy= None): category_slug = hierarchy.split('/') parent = None root = Category.objects.all() for slug in category_slug[:-1]: parent = root.get(parent=parent, slug = slug) try: instance = Category.objects.get(parent=parent,slug=category_slug[-1]) except: instance = get_object_or_404(Post, slug = category_slug[-1]) return render(request, "post/detail.html", {'instance':instance}) else: return render(request, 'post/categories.html', {'instance':instance}) templates/categories.html {% extends 'base.html' %} {% load static %} {% block head_title %} {{ instance.name … -
Django customized user model.... where does user.model(...) come from?
So, I am working my way through the jungle of the django documentation in order to create an online classifieds app. Since users are supposed to be anble to post their own classifieds online, I need to make use of the user authentication system. However, they need to be able to log in by email instead of username, which is why I need to come up with a customized user model. Now, the example walk-through thats contained in the django documentation seems helpful: https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#a-full-example In order to understand django better, I am trying to go through the example line by line, and there is a point that I don't quite get: class MyUserManager(BaseUserManager): def create_user(self, email, date_of_birth, password=None): """ Creates and saves a User with the given email, date of birth and password. """ if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), date_of_birth=date_of_birth, ) I don't get where the "self.model(...)" comes from. Is it a method? I cannot find it in BaseUserManager... where is it defined? I don't even quite know how to phrase the question precisely because I'm so puzzled about it... could anybody just enlighten me about what we are defining here … -

django filter on listed jsonfield to return exact list object
We have a postgres JSONField class Demo_Model(models.Model): urls_results = JSONField(blank=True,null=True,default=dict) from mainapp.models import Demo_Model j1 = [{"name":"John","age":"15"},{"name":"cena","age":"21"}] j2 = [{"name":"Shawn","age":"9"},{"name":"Michale","age":"19"}] Demo_Model(urls_results=j1).save() Demo_Model(urls_results=j2).save() Now we have inserted our JSON data into 2 objects for Demo_Model, When we filter out the results based on keys and values of json data of urls_results field. >>> x = Demo_Model.objects.filter(urls_results__contains=[{"name":"cena"}]) >>> x <QuerySet [<Demo_Model: Demo_Model object (1)>]> >>> for eachx in x: ... print(eachx.urls_results) ... [{'age': '15', 'name': 'John'}, {'age': '21', 'name': 'cena'}] it filters based on key and value and returns the matched object. How do I filter just matched json part from the result list, instead of entire field. FROM THIS [{'age': '15', 'name': 'John'}, {'age': '21', 'name': 'cena'}] TO JUST MATCHED OBJECT PART of DICT {'age': '21', 'name': 'cena'} I know we can just run a for loop across the resultant objects to match and return. for eachx in x: for key,val in eachx.items(): if key == 'name' & val == 'cena': return eachx But it's a problem when we have a large list of urls_results, I'm looking for another way instead of looping around, what is the most effective /fast way to solve this problem? -

Raising APIException in "update" Method of ModelSerializer does not Respond with Desired Status Code
I have a field that should not be updatable, which I've found out update method on ModelSerializer is the best to do that. What I do, pretty much, is to: def update(self, instance, validated_data): if "content" in validated_data: raise APIException( _("whatever error message is"), status.HTTP_403_FORBIDDEN, # or plain int, 403 ) return super().update(instance, validated_data) Oddly, the response's body is proper, which is: {"detail":"whatever error message is"} However, due to some unknown reason, it does not respond with status code 403, instead it responds with 500. 500 occurs when any exception is thrown during runtime in Django, yet the documentations of DRF clearly states that it especially handles APIException and responds accordingly. I do not know why it responds with 500. Environment Python 3.7.4 Django 2.2.7 Django Rest Framework 3.10.3 -
405 method not allowed while refreshing JWT Token - Django, Angular
I'm using JWT Authentication in my Django/Angular project and weird thing happens when I'm trying to get a new access token when the old one expired. I get a 405 POST METHOD NOT ALLOWED. I've set up corsheaders to allow all the methods and external hosts to access the app. The request looks fine as I'm sending the refresh token to get a new access token. What I've noticed is that it happens only on the pages which are sending POST request to django to access some data before displaying it. When I'm on a page that sends GET request or nothing, obtaining new token works perfectly good. Please take a look at the code and the responses.

How could I query a MySQL DB to pull out all entries with an AD User's name in it while using Python/Django?
Long story short, we are running some cleanup processes on our Tableau Server environment. What I need to do is have users login to the Django page with LDAP (that's a battle for another day), then have a query run automatically that will display their workbooks in an html table. I already have the SQL DB being built, I just need to figure out how to display it to my users and how I will get it to return output in some way that flags a workbook for deletion. Any thoughts on this? PS, I am fairly new to Django and models in particular, Python not so much. -

Django Get Entries Separated by Month
I've got an object called entry. This object has a CharField, a DateField and a ForeignKey to a status. (The status could be "Error" or "Warning") I now want to do a page where the user can see how many entries with the status "Error" and "Warning" got created a certain number of months until today. I already got the logic that the url has a kwarg that shows the number of months. Here is what I have so far in my views.py: class graph_view(View, LoginRequiredMixin): def get(self, request, **kwargs): timeline = get_object_or_404(Timeline, id=kwargs.get('pk')) months = kwargs.get('months') The Result should look something like this: August: 5 Errors, 2 Warnings September: 4 Errors, 6 Warnings October: 0 Errors, 5 Warnings November: 2 Errors, 4 Warnings In the excample above the user selected that he wants to see the entries over the last 4 months. Does anyone have an idea how i can query these entries? Thanks for any help. -

How did a hacker produce this GET request?
I am just about to go live with a website and am addressing security issues. The site has been public for some time but not linked to the search engines. I log all incoming requests and today noticed this one: GET /home/XXXXX/code/repositories/YYYYY-website/templates where XXXXX is a sudo user on my server and YYYYY is my company name. This is actually the structure of my Django project code. My website is coded using Django and runs under Apache2 on Ubuntu. My question is how can this guy possibly know the underlying code/directory structure on my server, in order to create this request? Their IP is : 66.249.65.221. They come up as 100% a hacker on https://ip-46.com Any contributions welcome. -

I am just wondering if anyone has any ideas on how to approach this problem? Cheers -
