Django Retrieve last 10 records for a given query
I was reading the django documentation, and thought this would work to limit to resulting query results to the last 10 results, but it isnt doing that. Here my db query: TSUH = TSUH.objects.filter(FKToUser_id=request.user).all()[10:] TSFH = TSFH.objects.filter(FKToUser_id=request.user).all()[10:] TSJH = TSJH.objects.filter(FKToUser_id=request.user).all()[10:] return render(request, page.html', { 'GivenTSUH':TSUH }) my template contains: {% if TSUH %} {% for T in TSUH %} <li>{{ T.scanBegin }}<span> to <span>{{ T.begin }}</span> </li> {% endfor %} {% else %} It appears there are no results. {% endif %} This is returning a lot more than 10 results for each query. is the all() throwing it off? Thoughts? Thanks -

Bootstrap-ui Modal is coming up blank when set inside angular-gantt
I am having difficulties trying to get my modal to come up. I am not sure if it is because modal is not compatible with angular-gantt or if I have the code wrong. At the moment I get a darker screen as if there should be a modal there. Here is the code for the button in the gantt: JS: 'content':'<i class=\"fa fa-cog\" data-toggle="modal" data-target="#hp_modal" ng-click="scope.show_details(task.model)"></i>' + 'Gant Object' Html: <div class='modal fade' id='hp_modal'> <div class='modal dialog'> <div class='modal-content'> <div class="modal-header"> <h3>This is HP modal</h3> </div> </div> </div> </div> And here is an Image of after I click on the cog: https://imgur.com/a/CazzaLK -

Accessing third party POST API
I have a third party POST API, for example: https://testenv/api/1.0/make_project/ which posts a payload like: [{'name' :'project_1' ,'created_by' :'prat' }] This json data is posted to the third party database. How could I create an API in my application to send over a payload to this third party api and would my request be a post request? And how would I go ahead with this and what all should I know about the third party api before implementation? -

How to get TextField to render in API Browser in DRF?
Using DRF, I have a User model that includes an Address field, which is a TextField. When I view the UserList endpoint in the API Browser, Address looks like this: "address": "<django.db.models.fields.TextField>", From the documentation, I thought I needed this in my serializer: address = serializers.CharField( max_length=1000, style={'base_template': 'textarea.html'}, ) ...but that didn't fix the problem. The same thing is happening with PhoneNumberField type fields: "phone_number": "<phonenumber_field.modelfields.PhoneNumberField>", I redefined them in my serializer as CharField. -

Why File is not uploading in specified upload path in models in Django, It is uploading in expected directory when uploaded from the admin
I've been trying to upload some files using normal CRUD operation in Django. The files are uploading at the media directory of the project while normally uploaded and when I try to upload the files from the admin area it is uploading in the expected directory ie. inside media/cv. I've defined the models for the database and also defined the media root and added it into the urlpatterns variable too. All seems okay and works just fine when I try to upload the file from admin view but when I try to upload file normally the file is uploaded directly in the media directory, not in media/cv. settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'home', ] MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') urls.py in project level from django.conf import settings from django.conf.urls.static import static from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('home.urls')) ]+static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) models.py from django.db import models class Student(models.Model): cv = models.FileField(upload_to='cv') urls.py from django.urls import path from . import views urlpatterns = [ path('student/create', views.insert_student, name='create_student'), ] views.py from django.core.files.storage import FileSystemStorage from django.shortcuts import redirect from .models import Student def insert_student(request): if request.method == … -
django template falling into unexpected logic
I have a view that is supposed to be gathering all the objects for a currently authenticated user from three tables TSFH, TSUH, and TSJH and gather all those objects for the currently logged in user, if that user exists. However, my view logic is currently falling into the else statement it appears. Can someone help me debug why this might be happening? My tables have data for the currently logged in user, so I am not sure why this is happening. Views.py def SHO(request): TSUH = TSUH.objects.filter(FKToUser_id=request.user).all() TSFH = TSFH.objects.filter(FKToUser_id=request.user).all() TSJH = TSJH.objects.filter(FKToUser_id=request.user).all() return render(request, 'page.html', { 'TSUH':HasTSUH, 'TSFH':HasTSFH, 'TSJH':HasTSJH }) templates/page.html {% autoescape on %} {% if HasTSUH %} {% for t in HasTSUH %} <li>{{ t.begin }}<span></li> {% endfor %} {% elif HasTSFH %} {{ HasTSFH }} {% elif TSJH %} {{ TSJH }} {% else %} It appears you haven't done anything yet. {% endif %} However it keeps displaying: It appears you haven't done anything yet. what am i doing wrong here? thanks -
Django secure django-rest-framework-simplejwt
I am trying to create a JWT token authentication my Django rest application for that I am using: django-rest-framework-simplejwt I can generate an access token and I want to decode that token and only I can see the decoded values. Right now when I generate the access token it can be decoded easily. I am using this to decode: decodedPayload = jwt.decode('key_secret',None,None) And I can see my details like this: "decode": { "token_type": "access", "exp": 1558361039, "jti": "d8317cf3849f42d2b019359ab49206ce", "user_id": 2 } I am getting a token using this route: path('api/token/', jwt_views.TokenObtainPairView.as_view(), name='token_obtain_pair'), Is there any way to edit this and get token with added values. And I want to decode it privately so that no one can see. -
Different bugs always raise the same error: ImproperlyConfigured: The included URLconf 'myproject.urls' does not appear to have any patterns in it
I have a pretty standard Django project with several apps, each with its own urls, models, forms, etc... My issue is that whenever I make a mistake in my code - e.g. writing a wrong name for a model field in a form "fields" attribute - the error raised is always the same: django.core.exceptions.ImproperlyConfigured: The included URLconf 'myproject.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. I would expect the error message to change according to the error made. This not happening makes everything extremely difficult to debug. Any ideas? -

Pass elements of list as a separated string to django methods

How to integrate a ranking algorithm in my Django application
I am building a simple hacker news website and would like some help on how to integrate a ranking algorithm for submitted posts. I understand that I can rank submitted posts via 'order_by', which I have done for now: def index(request): submitted_items = Submission.objects.all().order_by('-votecount')[:20] However, I would like to make the ranking more intelligent by factoring in the date at which the submission was made. To give a little bit more context, I used this code block from a tutorial that I found as a base for trying to figure out how to implement such an algorithm: class HomeView(TemplateView): template_name = 'home.html' def get_context_data(self, **kwargs): ctx = super(HomeView, self).get_context_data(**kwargs) now = timezone.now() submissions = Link.objects.all() for submission in submissions: num_votes = submission.upvotes.count() num_comments = submission.comment_set.count() date_diff = now - submission.submitted_on number_of_days_since_submission = date_diff.days submission.rank = num_votes + num_comments - number_of_days_since_submission sorted_submissions = sorted(submissions, key=lambda x: x.rank, reverse=True) ctx['submissions'] = sorted_submissions return ctx But I couldn't get this to work in my own application. I guess another way to phrase my question is this. Django/Python has a standard order_by() function that allows me to sort data, most simply in an ascending or descending order. Is there a way to create my … -
Database/application structure for hierarchical model in Django
Say we are modeling a hierarchical system, where a model / database row can have a "parent". In addition, an object can have a number related models. Now, the idea is that if a row does not have its own value for a certain relation, it assumes the 'parent' relations. For example: Model table: id | parent_id | name | --------------------------- 1 | NULL | One | 2 | 1 | Two | 3 | 1 | Three | 4 | 3 | Four | 5 | NULL | Five | Relation table: id | model_id | value | --------------------------- 1 | 1 | Cheese | 2 | 2 | Crackers | With the above data, I want the result to be that: model1.relation.value == Cheese (directly, no parent) model2.relation.value == Crackers (directly, even though parent model1 has a different value) model3.relation.value == Cheese (Through the parent value, model1) model4.relation.value == Cheese (Through its parent, model3, who gets its value through its own parent) model5.relation.value == NULL (model5.relation has no value, and model 5 has no parent) Is there an accepted / standard way how to model this (in a Django application, or in general)? Or might this even be … -
Django bulk delete certain queryset
I have a multiple objects of a File model. I am trying filter and delete these files based on a certain condition but am failing to succeed in this. Consider the following I have 3 File objects: File1 File2 File3 I tried to override the delete() function of the model like this: def delete(self, using=None, keep_parents=False): test_qs = File.objects.filter(file_name='File1') if test_qs: for x in test_qs: x.delete() super(File, self).delete() When I go to my Django Admin, select all the files (File1, File2 & File3) and bulk delete them, all of them all deleted instead of just File1. In my Django Console File.objects.filter(file_name='File1') returns a queryset with just File1. I also tried to override the pre_delete signal like this: @receiver(pre_delete, sender=File) def delete_certain_files(sender, instance, **kwargs): test_qs = File.objects.filter(file_name='File1') test_qs.delete() This however, results in a RecursionError How do I make sure to just delete the File objects that meet a certain condition upon bulk deletion? -

Using MQTT protocol connect devices to server with RabbitMQ and Django
I would like to to create a connection between the device(Arduino) and web server by using the MQTT protocol. As tools, we will use RabbitMQ, Django, and Django-channels for web socket.
