Type error Exception Value: 'Profile' object is not iterable
Not sure what's going wrong here. IF two users have both voted yes to each other, hence both having a vote attribute of True, I am attempting to add both of them to my matches database.

How to return a template from a function without the request argument?

I want to make an element in my template based on the value of finished. Something like this: scraper/home.html {% if finished %} <p>Finished!</p> {% endif %} I'll appreciate your help on this.

Django schema explorer simple recursive algorithm - confused by results / how to fix
I am using Django and have a couple of use cases for which the ability for objects to trace their relationships through several models is required. I don't want to hand-code this functionality for every model. Some example models: class Project(models.Model): project_name = models.CharField(max_length=200, default="development_project") class Question(models.Model): project = models.ForeignKey(Project, default=1, on_delete=models.CASCADE) question_text = models.CharField(max_length=200, default="question text") class Extra(models.Model): extended_q = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) summary_of = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) content = models.CharField(max_length=200, default="simple summary") class Answer(models.Model): question = models.ForeignKey(Question, default=1, on_delete=models.CASCADE) user = models.ForeignKey(User, default=1, on_delete=models.CASCADE) Using models as nodes of a network and relationships as edges, this seems like it should be manageable, but for some complexity where there are 'redundant' edges - do we permit an Extra to summarise Answers from a different project? my use cases will be: a models.Manager class that can act as the default manager for a sub-class of Django apps that work together in a unified site and help do the sort of row-separating management that will keep users, even in the admin, from getting under each others feet. an overall app using ContentTypes that can help the user build datasets and organise tables for dataframes (taking fks and making them appropriate category … -
Label and input value overlaps with django-material and datepicker
So the idea is that I need a pop-up and in that pop-up there should be a form in which you have to choose the date, so the pop-up have a Form object with a TextField that emulates the a date input to use the datepicker of material, the problem comes with the label of that input that overlaps with the input itself like this. I tried using javascript to add the class "active" to the label when you click the input because that is what triggers the label to go up but it doesn't recognize it and doesnt apply the class. The html renders like this: <div class="input-field col s12 required" id="id_fecha_cobro_container"> <i class="material-icons prefix">insert_invitation</i><input id="id_fecha_cobro" name="fecha_cobro" type="date"> <label for="id_fecha_cobro">Fecha de Cobro</label> </div> This is the modal in django: {% block change_form %} {% form %} {% part form.fecha_cobro prefix %}<i class="material-icons prefix">insert_invitation</i>{% endpart %} {% endform %} {% prepopulated_fields_js %} {% endblock %} This is the form class: class AvisoVacacionForm(forms.Form): fecha_cobro = forms.DateField(label="Fecha de Cobro", required=True, widget=forms.TextInput(attrs={'type': 'date'})) def __init__(self, *args, **kwargs): super(AvisoVacacionForm, self).__init__(*args, **kwargs) This is what I've tried using javascript: $('#id_fecha_cobro').click(function(){ $("label[for='id_fecha_cobro']").addClass("active") }); -

Error When Debugging Django project with ImageFields in Visual Studio Code
I spent so long solving this problem I wanted to post it in case it helps others. I have a django project in Visual Studio Code and I configured a virtual environment for the project. I would run the project in the Integrated Terminal using manage.py runserver after activating my virtual environment and that worked. I created a debug configuration with the default launch.json for django projects. Running the debugger, I got this error: (fields.E210) Cannot use ImageField because Pillow is not installed.HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "python -m pip install Pillow". Pillow was installed in the virtual environment as well as my global python installation. -
"Post.user" must be a "User" instance
I am new to using django and I'm creating a simple webpage that takes in user input and saves it to the Model Form models.py: from django.db import models from django.contrib.auth.models import User # Create your models here. class Post(models.Model): post = models.CharField(max_length=100) user = models.ForeignKey(User, on_delete=models.CASCADE) forms.py from django import forms from .models import Post class HomeForm(forms.ModelForm): post = forms.CharField() class Meta: model = Post fields = ('post',) views.py from django.shortcuts import render, redirect # Create your views here. from django.http import HttpResponse from django.views.generic import TemplateView from .forms import HomeForm class HomeView(TemplateView): template_name = 'home.html' def get(self, request): form = HomeForm() return render(request, self.template_name, {'form': form}) def post(self, request): form = HomeForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.user = request.user post.save() text = form.cleaned_data['post'] form = HomeForm() return redirect('home.html') args = {'form': form, 'text': text} return render(request, self.template_name, args) When I run the server the webpage comes up normal but when I type in some input an error page pops up and says : ValueError at / Cannot assign ">": "Post.user" must be a "User" instance. Any Help would be appreciated! -
'DatabaseOperations' object has no attribute 'geo_db_type' error when deploying GeoDjango to Heroku
I am tryin to deploy a geodjango app to Heroku following this Tutorial but I ran into an error when I run git push heroku master and get this error in the console Using geos version: <?xml version="1.0" encoding="UTF-8"?> Fetching, caching and installing geos https://dulaccc-buildpack-geodjango.s3.amazonaws.com/heroku-18/geos-<?xml version="1.0" encoding="UTF-8"?>.tar.gz gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now When I use this link official heroku-geo buildpack and remove the buildpacks from the previous tutorial the build completes successfully but I get a "DatabaseOperations' object has no attribute 'geo_db_type" when I run heroku run python manage.py migrate on my local environment.

Django Unable to update model based on link click
I'm trying to update the model record of a file when it is downloaded from the server. I am currently using a custom tag that finds the appropriate record and changes the 'used' Boolean to True, however I now realise that this occurs when the link is rendered, not when clicked. It's pretty clear this is not the way I should be doing this, but haven't found an alternative with my searching. Any help would be greatly appreciated! profile.html {% for x in source %} {% if forloop.counter <= 4 %} <div class="content-section"> <div class="media-body"> <h2 class="account-heading">{{ x.video_id }}</h2> {% for y in records %} {% if x.video_id == y.sourcevideo.video_id %} <div class="media-body"> <video width="320" height="240" controls> <source src="{{ y.highlight.url }}" type="video/mp4"> Your browser does not support the video tag </video> <h1>{{ y.highlight_id }}</h1> <br> <a class="btn" href="{% downloaded y.highlight.url y.highlight_id %}" download>Download</a> </div> {% endif %} {% endfor %} </div> </div> {% endif %} {% endfor %} templatetags/analytics.py from django import template from highlights.models import Highlight register = template.Library() @register.simple_tag def downloaded(url, pk): e = Highlight.objects.get(highlight_id=pk) e.used = True e.save() return url From views.py class ProfileView(ListView): model = Highlight template_name = 'users/profile.html' context_object_name = 'records' ordering = ['-date_created'] @method_decorator(login_required) … -

Is it possible to get an interactive django shell using the test database?
When running tests, you can do: ./manage.py test --keepdb To run your tests, and keep the test database. Is it possible to have the django shell actually connect to it, so we can interactively access the test database the same way the Django shell can normally work with the production database? Note that the answer and its comments here imply that you can access it by doing something like: from django import test test.utils.setup_test_environment() from django.db import connection db = connection.creation.create_test_db(keepdb=True) But when I do that, my database appears to be empty when I do queries. -
