How to stop objects (posts) from overlapping each other
I am trying to create the landing page of a blog, however, posts keep on overlapping with other content. How can I stop these objects from overlapping each other? I have attached an image of how the frontend looks like for better understanding. This is how the frontend looks like Here is my index.html <style> .headslider{ background-image: url("{% static 'assets/img/post-slide-1.jpg' %}"); } .postslide{ background-image: url("{% static 'assets/img/post-slide-2.jpg' %}"); } .postslide1{ background-image: url("{% static 'assets/img/post-slide-3.jpg' %}"); } .postslide2{ background-image: url("{% static 'assets/img/post-slide-4.jpg' %}"); } .box{ width: 250px; height: 200px; margin:20px; padding: 20px; } </style> </head> <!-- ======Some sections skipped====== --> <!-- ======= Post Grid Section ======= --> <section id="posts" class="posts"> <div class="container" data-aos="fade-up"> <div class="row gx-5"> {% for post in posts %} <div class="post-entry-1 col-lg-3 box mx-1"> <a href="single-post.html w-300 h-200"><img src="{{post.image.url}}"></a> <div> <div class="post-meta"><span class="date">Culture</span> <span class="mx-1">&bullet;</span> <span>{{post.created_at}}</span></div> <h2><a href="">{{post.title}}</a></h2> </div> <p class="mb-4 d-block">{{post.body|truncatewords:20}}</p> <div class="d-flex align-items-center author"> <div class="photo"><img src="{% static 'assets/img/person-1.jpg' %}" alt="" class="img-fluid"></div> <div class="name"> <h3 class="m-0 p-0">OlePundit</h3> </div> </div> </div> {% endfor %} <br> <!-- Trending Section --> <div class="col-lg-3 mx-10 pl-10"> <div class="trending"> <h3>Trending</h3> <ul class="trending-post"> <li> <a href="single-post.html"> <span class="number">1</span> <h3>The Best Homemade Masks for Face (keep the Pimples Away)</h3> <span class="author">Jane Cooper</span> </a> … -
Rendering multiple matplotlib plots in my Django view using BytesIO
I'm struggling with rendering multiple matplotlib plots in my Django View. When doing it with one plot, it works fine, but as soon as i try adding more than one plot in my view, the second plot doesn't render correctly. I'm quite sure it has something to do with how i'm using BytesIO(). In my HTML, when commenting out the Portfolio construction plot part (first plot), the Efficient frontier plot renders perfectly (second plot). So it's definitely the portfolio plot that comes first that messes up the efficient frontier one, but why? from re import search from sys import set_coroutine_origin_tracking_depth from django.http.response import HttpResponse, HttpResponseRedirect from django.shortcuts import redirect, render from django.db.models import Q from datetime import datetime, date from django.http import JsonResponse from django.views.decorators.csrf import csrf_exempt from io import BytesIO import base64 import pandas as pd import seaborn as sns from matplotlib.pyplot import figure from matplotlib import pyplot as plt sns.set() import os import riskfolio as rp from .forms import UploadFileForm def index(request): data_path = format(os.getcwd()) + "/app/data/" df = pd.read_csv(data_path + "portfolio_data.csv", sep=";", decimal=",") df['Date'] = pd.to_datetime(df['Date'], infer_datetime_format=True) df.set_index('Date', inplace=True) df = df.sort_values(by="Date", ascending=True) for column in df: df.insert(loc=df.columns.get_loc(column)+1,column= column + " Returns", value=df[column].pct_change()) returns_columns = [x for … -

How to use same serializer class for get and post method in Django?
I have been trying, but fail miserably, to use only a single serializer class for both post and get api call. I have a Person model which has some fields. What I need is I want to create a person object using post API with certain fields and however needs to show some other fields while doing get request. For eg: My model: class Person(models.Model): name = models.CharField(max_length=255,blank=True) email = models.EmailField(unique=True) phone = models.CharField(max_length=16) address = models.CharField(max_length=255,blank=True) roll = models.IntegerField() subject = models.CharField(max_length=255,blank=True) college_name = models.CharField(max_length=255,blank=True) Now my serializer will look like this. class PersonSerializer(serializers.ModelSerializer): class Meta: model = Student fields = ['id','email','name','phone','roll','subject','college_name', 'address'] For eg, I have a view that handles both post and get request (probably using APIView), then what I need to do is, to create a person object I only using name, phone, and email. So for post API call, I only need three fields whereas while calling the get API I only need to display the fields name, roll, subject, and college_name not others. In this situation, how can I handle using the same serializer class?? -

How do I create a dynamic "About Me" page in Django?
Here, by dynamic I mean, I wouldn't want to update my template in order for me to update changes. I'd want them to edit in the admin page on my production site. At first, I thought I'd create a model for "About Me" itself, but then I'd need to create a model for just one instance. I need help with this, better ways to edit my pages dynamically on the admin site. -
Should i manualy save client ID and client secrets? using django rest framework
This is my first django rest framework project and my question is about manually saving clientID and client secrets vs using a package that automates this. What I am trying to build is something similar to the Spotify developer dashboard. It gives each user the option to create several projects. Once a project is created, the user gets a client ID and a client secret for the project (both are different for each project the user creates). Like in other API dashboards users can generate a new client secret. This is what it looks like: My first shot at solving this topic was to handle all user-level authorization (like browsing through the website using the developer dashboard) with simple-jwt token authorization, which will handle the blacklisting of tokens and many other things itself. But for the project level authorization, I am manually saving a permanent client ID and client secret as UUID to the project model. Here you can see the project model (it extends from a base model which includes a UUID as Primary key + date created + date modified). Blacklisted client secrets will be moved to a custom blacklist model when users want o generate a new … -

how to keep loop runnning while user gets redirected back to form after making a post request to start the loop
I have a django app with a view that handles a post request from a user to start an infinite loop. The problem is after succesful post request loop starts and the browser keeps loading waiting for response from the server resulting to timeouts from proxy server handling this request. Is there anyway to start the loop and keep it running while redirecting or giving back response to the browser to prevent timeouts view code below: def ticket_miner(request): mining_urls = credentials.mining_urls if request.method == 'GET': form = forms.UpdateForm() return render(request, 'tickets/mine.html', {'form': form}) else: net_test = network_acess.network_test(urlpaths.net_urls) while net_test: with requests.session() as s: try: print('logging in ....') s.post(login_url, data=payload, headers=headers, timeout=5) r = s.get(success_url, timeout=5) print(r) if r.status_code == 200: print('Logged in successfully') while r: count = 0 for mining_url in mining_urls: r2 = s.get(mining_url, timeout=5) count += 1 response_result = r2 if response_result.status_code == 404: print('TICKET NOT FOUND!') pass else: new_data = response_result.json() miner.ticket_mapper(new_data) print('mining') continue print('mining successfull restarting ...') else: print('Unable to authenticate... redirect detected') except requests.exceptions.ConnectionError as e: print(f'ConnectionError: {e.response} response.

Django automated email sending
I am building a multivendor market place using django and I have to send automated emails for two reasons. I have to verify their email each time someone signs up (A verification email will automatically be sent when they completed their form). Automated email is sent to the user when order is ordered. All the above worked fine when I test them, but I used my gmail account for that purpose. I have read that gmail is not the perfect choice for business purposes. Plus there is no online payment system in my country for payed services and all the free options I see can only send very limited emails per day. So should I continue using gmail? Or is there any other system I can use? Thank you in advance! -
How can I utilize the JWT for authintication and authorization in Django

I mean for example, how can I use Django and JWT to make an authorized group of users? -
Correct way to define the initial value of a form field in Django from a database, when database values may change
I am trying to create an interview feedback capture app using Django. The interview feedbacks follow a template. The template would evolve with time. Therefore whenever a new interview feedback template is available, it is updated to the database by an admin user. Whenever an interviewer opens the app, he should see the latest value of the template available in the database as the initial value of the feedback form. Currently I am able to provide the initial value of the feedback field using the 'initial' argument of the feedback field. Below is the code: from django import forms from .models import R1 from .model_templates import template_R1 from ckeditor.widgets import CKEditorWidget class R1Form(forms.ModelForm): interview_date = forms.DateField(widget = DateInput()) feedback = forms.CharField(widget = CKEditorWidget(), initial = template_R1.objects.all().last().template) class Meta: model = R1 fields = ['interview_date', 'interviewers', 'comment', 'recommended_level', 'progress'] The problem with this approach if that if the template is updated the form field still shows an earlier snapshot of the template when the django server was started. Is there any other way the form field would show dynamic values as soon as the template is updated in the database? -

Django AssertionError when testing Create View
I'm running some tests for my app 'ads', but when I try to test the CreateView it fails with the following message: AssertionError: 'just a test' != 'New title' Here's the test: class AdTests(TestCase): def setUp(self): self.user = get_user_model().objects.create_user( username='test_user', email='test@email.com', password='secret' ) self.ad = Ad.objects.create( title='just a test', text='Ehy', owner=self.user ) def test_ad_create_view(self): response = self.client.post(reverse('ads:ad_create'), { 'title': 'New title', 'text': 'New text', 'owner': self.user.id, }) self.assertEqual(response.status_code, 302) self.assertEqual(Ad.objects.last().title, 'New title') self.assertEqual(Ad.objects.last().text, 'New text') So it could be that the test fails in creating a new ad, and then it compares the fields with the first ad in the setUp method.

Filter Categories from list of Products in Django templates
So I'm working on this Django e-commerce website where I'm supposed to filter the products on my page based on three separate categories. Since there were only three fixed categories, I decided to create a dictionary in my model class for Products and thought there would be a way to filter products later on in my templates accordingly using a {%For%} loop. It's not working as I expected tho and I'm getting errors, probably because I'm not that familiar with Django and don't know how to get my way around it. Would greatly appreciate the help! (I've attached some screenshots for context) MODELS.products screenshot working implementation of for loop that directly shows all products Views.catalogue -
How to render a value of a single variable to a template using Django?
I am building a web application where the completion of the project (status) is returned to the client(user) through a dynamic URL. The view looks something like this:1 I want to retrieve the single value from phase field (phase field stores integer values from 1 to 10) and perform percentage = (phase / 10) * 100. How can I render the query phase and render percentage variable which stores the percentage, to template? Here's my model.py: from cmath import phase from pyexpat import model from django.db import models from sqlalchemy import delete class Project(models.Model): STATUS = ( ('Inititated', 'Inititated'), ('Paused', 'Paused'), ('In progress', 'In progress'), ('Aborted', 'Aborted'), ('Completed', 'Completed') ) PHASE = ( ('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('5', '5'), ('6', '6'), ('7', '7'), ('8', '8'), ('9', '9'), ('10', '10') ) p_id = models.IntegerField(null=True) p_name = models.CharField(max_length=100, null=True) c_name = models.CharField(max_length=100, null=True) c_mail = models.CharField(max_length=100, null=True) init_date = models.DateField(null=True) ect = models.DateField(null=True) status = models.CharField(max_length=200,null=True, choices=STATUS) collabs = models.IntegerField(null=True) phase = models.CharField(max_length=100,null=True, choices=PHASE) def __str__(self): return self.p_name views.py: from cmath import phase from multiprocessing import context import re from unicodedata import name from django.shortcuts import render from django.http import HttpResponse from .models import Project from django.shortcuts import … -
Form not submitting to correct url in django
Im making a web app in django and im having a problem with a form which isnt submitting to the correct place searcc.html <form method='POST', action='/saveApply'"> {% csrf_token %} <div class="JobSub"> <input value="{{user.id}}" name="usrid"> <input value="{{comp.id}}" name="compid"> <button type="submit">Submit</button> </div> </form> views.py def saveApply(request): current_user = request.user if request.method == 'POST': # Foreign key to User is just the username savedApply.objects.create( user = request.POST.get('usrid'), company = request.POST.get('company') ) return render('main/profile.html') # Change later return redirect('login') The confusing thing is, when I press on the submit button Im not even getting sent to the login view. I am getting sent to the home page. I think the problem has something to do with the fact that this html page is getting included in another. main.html {% include 'main/search.html' %} {% endblock %} Main.html is also inheriting from another file -
Why can't i display my foreign key instance in Django?
I'm having trouble in viewing items from a list using foreign key. I have no problems with other models, but this one seems tricky. I'm not getting something I guess... The assignement is about creating a rental place that rents movies, books and music cd's. I've created a model for Cd's and hooked a model called "songs" to it with a foreign key. Here's the code: Models: class Cd(models.Model): cd_band=models.CharField(max_length=100) cd_title=models.CharField(max_length=100) CD_GENRE= ( ('POP', "POP"), ("HIP", "Hip-Hop"), ("ROC", "Rock"), ("BLU", "Blues"), ("SOU", "Soul"), ("COU", "Country"), ("JAZ", "Jazz"), ("CLA", "Classical music"), ) cd_genre=models.CharField(max_length=3, choices=CD_GENRE) cd_length=models.DurationField() cd_rental=models.ForeignKey(Rental, on_delete=models.CASCADE, default=1) class Songs(models.Model): song=models.CharField(max_length=50) song_duration=models.CharField(max_length=10, default='') list_number=models.ForeignKey(Cd, on_delete=models.CASCADE, related_name='song_name') def __str__(self): return "{} {}".format(self.song, self.song_duration) template: {% block content2 %} {%for songs in object_list%} <div class="song-entry"> <h3>{{object.song_name}}</h3> </div> {% endfor %} {% endblock content2 %} -
Django Query Annotation Does Not Support math.tan() Calculation
I have a django 3.2/mysql website. One of the tables, Flights, has two columns, angle and baseline. These two columns are combined in a view to display the value altitude using the formula altitude = baseline * tan(angle). I am building a search form for this table, and the user wants to search for flights using a minimum altitude and a maximum altitude. My normal approach to the problem is to gather the inputs from the search form, create appropriate Q statements, and use query the table with filters based on the Q statements. However, since there is no altitude field, I have to annotate the query with the altitude value for the altitude Q statement to work. It seems that a query annotation cannot use an expression like math.tan(field_name). For example, Flights.objects.annotate(altitude_m=ExpressionWrapper(expression=(F('baseline') * math.tan(F("angle"))), output_field = models.FloatField(),),) generates the error builtins.TypeError: must be real number, not F whereas the expression Flights.objects.annotate(altitude_m=ExpressionWrapper(expression=(F('baseline') * F("angle")), output_field = models.FloatField(),),) does not generate an error, but also does not provide the correct value. Is there a way to annotate a query on the Flights table with the altitude value so I can add a filter like Q(altitude__gte= min_altitude) to the query? Or, is …
