How to use django AppConfig.ready()
I can't seem to get my ready function under my AppConfig to work. Here is my code from apps.py: from django.apps import AppConfig from django.contrib.auth.models import User from django.db.models.signals import post_save, post_delete from django.db.models import Max, Count from .models import Player, PlayerStats, TotalLevels class BloxorsConfig(AppConfig): name = 'bloxors' def ready(self): MaxCurrentLevel = PlayerStats.objects.aggregate(max_levels=Max('level_no'))['max_levels'] PlayerCount = Player.objects.aggregate(count_players=Count('player_name', distinct=True))['count_players'] print(MaxCurrentLevel, PlayerCount) I read in the documentation that ready() gets called each time at the beginning of manage.py runserver but then why does nothing happen. Ideally I was expecting it to print the two values MaxCurrentLevel, PlayerCount. Can someone point out what I am doing wrong and help solve this? As always, I greatly appreciate your answers! -
Navbar inherited from base.html using Django templating doesn't render styles properly
I'm implementing a navbar and I wanted to use django templating for the DRY principle. The first picture is its appearance before templating, the second one is after templating. (https://imgur.com/a/FOEqKFB) How do I get the css files to render properly in the inherited html file? I thought it was a case of me not calling the CSS files in base.html (like this one: another similar answer), but I checked the code for base.html and I've already called the Bootstrap CDN for the navbar styles on the header. What went wrong in my code? This is the relevant code for the problem: base.html <!DOCTYPE html> {% load static %} <html lang="en"> <head> <title>{% block title %}Title{% endblock title %}</title> {% block head_favicon %} <link rel="icon" type="image/x-icon" href="/favicon.ico"> {% endblock head_favicon %} {% block head_meta %} {% block head_meta_charset %} <meta charset="UTF-8"> {% endblock head_meta_charset %} {% block head_meta_contentlanguage %} <meta http-equiv="X-UA-Compatible" content="ie=edge" value="en-US"> {% endblock head_meta_contentlanguage %} {% block head_meta_viewport %} <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0"> {% endblock head_meta_viewport %} {% endblock head_meta %} {% block head_css %} {% block head_css_site %} <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> {% endblock head_css_site %} {% block head_css_section %}{% endblock head_css_section %} {% block head_css_page … -
django post_save causing IntegrityError - duplicate entry
I need help to fix the issue IntegrityError at /admin/gp/schprograms/add/ (1062, "Duplicate entry '65' for key 'PRIMARY'") I am trying to insert a row into a table SchProgramForStates (whenever new entry gets added into a model SchPrograms) with two columns state_id (taking it from django session) and program_id trying to take it from SchPrograms model class .

How to run Object_detection_image.py, which is outside my django project?
I am using windows 10 Django version: 2.1.1 with Python version: 3.5 I have my TensorFlow object detection API, that trained my images which is totally outside of my Django project. However, I created my Django project after that in the same environment that I had my TensorFlow object detection models. Both of them with the same (python version: 3.5). Before creating the Django webpage, I always needed to run my 'Object_detection_image.py' from anaconda prompt line, otherwise, I got an error. My question is: how I can specify my Object_detection_image.py path directory in the setting.py in Django using anaconda prompt line? When I write my directory like this: C:\tensorflow1\models\research\object_detection then how I can use anaconda prompt line in this path? because if I write it like this, it doesn't work. please help me. Thank you. -

Django template object not showing
So I've come across this weird thing. I can't pass data within the template unless it's within the forloop. for example.. I can pretty much print a variable just within a for loop but something outside a forloop is not showing up. {{listings.make}} <<<< This isn't printing {% for listing in listings %} <p>{{listing.make}}</p> <<<< This is printing {% endfor%} def search(request): queryset_list = Vehicle.objects.all() context = { 'listings': queryset_list } return render (request, 'mainapp/new_listing.html', context) class Vehicle(models.Model): year = models.CharField(max_length=4, choices=YEAR) make = models.CharField(max_length=50, default="") model = models.CharField(max_length=50, default="") version = models.CharField(max_length=50, default="") description = models.TextField(max_length=50, default="") def __str__(self): return self.make Any idea what is going on actually.

Comparing value from html to context
I need to compare a value (variable) extracted from a page to context.

How to display Django BooleanFields selected true in template?
everyone! I created a model object. This object has several boolean fields. # models.py class TeamCharacteristic(models.Model): team = models.ForeignKey('Teams',on_delete=models.CASCADE) power1 = models.BooleanField(null=True, blank=True) power2 = models.BooleanField(null=True, blank=True) power3 = models.BooleanField(null=True, blank=True) power4 = models.BooleanField(null=True, blank=True) power5 = models.BooleanField(null=True, blank=True) class Meta: verbose_name = 'Team style' verbose_name_plural = 'Teams style' def __str__(self): return "{} 's style".format( self.team, ) Some of them are right and others are wrong.

Working with autofield and unique_constraint Django

As different students can have the same roll number if they are from different classrooms. I am aware of unique constraint. But even after unique_constraint I am still not sure how my rollNumber will increment of different classrooms. Like won't it be continuosly incrementing the rollNumber number which will obviously be unique for different or same class ? -
Is there any way to filtering the queryset dynamicaly in django forms for a foreignkey correct?
I am creating a form for this model class SemAssign(models.Model): staff = models.ForeignKey(User, on_delete=models.CASCADE) semester = models.ForeignKey(Subject, on_delete=models.CASCADE, default=1) def __str__(self): return f'{self.staff.username}' and my forms.py looks like class SemAssignForm(forms.ModelForm): class Meta: model = SemAssign fields = ['staff','semester'] And i made a queryset based on a user-defined filter as in my views.py def assign_sem(request): if request.user.is_staff: dept = request.GET.get('department') sem = request.GET.get('semester') form=SemAssignForm(request.POST) #form.fields['staff'].queryset = User.objects.filter(is_staff=True, profile__Department=dept) #form.fields['semester'].queryset = Subject.objects.filter(sem=sem) if form.is_valid(): SemAssign=form.save() return redirect('dashboard') When the query works perfectly the form is validated as wrong. And if i don't make query the form is validated successfully. I'm sure i missing somewhere in querying the foreignkey set. Can anyone sought me that? My friend suggested me with modelformset, but that is not my scope. I just want to filter the fields of SemAssign models based on a GET request filter. -

Django: Getting NoReverseMatch While Submitting the Form, URL has Slug

Where we should change initial data in the serializer?

How to make python in template to enter if condition only once
I have a some products and some pictures of in different models. While displaying all products I need to display 1 image in the table. I tried this: template : <tr class="check_items_row"> <td style="width:20px;"> <div class="checkbox lgi-checkbox m-t-5"> <label> <input class="check check_item" type="checkbox" value="{{instance.pk}}" name="delete_item"> <i class="input-helper"></i> </label> </div> </td> <td><a href="{% url 'products:product' pk=instance.pk %}">{{instance.auto_id}}</a></td> <td>{{instance.category}}</td> <td>{{instance.subcategory}}</td> <td>{{instance.name}}</td> {% for item in product_gallery %} {% if item.product == instance and test == 0 %} <td><img src="{{item.image.url}}" alt="Image" style="width:100px;"/></td> {% endif %} {% endfor %} </tr> {% endfor %} views.py def products(request): instances = Product.objects.filter(is_deleted=False).order_by('auto_id') product_gallery = ProductGallery.objects.all() context = { 'title': "Product ", 'instances' : instances, "product_gallery": product_gallery, "test": 0, } return render(request,'products/products.html',context) in my thoughts I just need to change the value of test in template if it enters the if condition once . This code is displaying all images of a product. I just need one image of every product. Here i will need to change the value inside if condition and reset to 0 after the for loop -
Django Signal that provides access to response of a request?
So far in our code we have implemented Django built-in signals for handling user login, logout, and failed login as well as db actions with pre-save, post_save and post_delete signals. I am looking to maintain consistency by performing some operations on the http response after a request has been made using signals. However, I do not see any built-in signal that grants access to the response object. I am aware of the request_finished signal but this does not seem to provide access to the response object. I have successfully achieved what I need using Django's process_response function in middleware but was wondering if there was a way I could maintain consistency and use a signal here as well. We are using Django 2.2 and DRF 3.8.2 -

Sass_Processor and Compressor Are Not Creating .css File with Django 2.2, No Errors
I recently decided to switch my project over to sass as I like the DRY-ness of it. To get set up, I followed these two sites: https://www.accordbox.com/blog/how-use-scss-sass-your-django-project-python-way/ and https://terencelucasyap.com/using-sass-django/ It seemed to be working the first time around, but then I made more changes to the .scss file and tried to recompile, but no changes were made. I found the generated .css file and deleted it, thinking it might regenerate it, but not it doesn't seem to be doing anything when I compile. I have tried moving around where the sass_processor is looking, and where to save it to, but now I'm not sure what the problem is. I am completely new to sass, and fairly familiar with Django so I'm sure this is a simple problem I am missing. I have been unable to find any questions related, as mine does not throw any errors.. there just isn't a file? When I run ./manage.py compilescss I get Successfully compiled 1 referred SASS/SCSS files. then I collect the static files and runserver but inside of the chrome inspector, I do not see a css file where I normally would and none in my directory either. setting.py """ BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) … -
