How do i work with 3 django models linked by a foreign field?
I've been able to display all offices in an election, but have been unable to display all candidates in an office on the same page models.py class Election(models.Model): name = models.CharField(max_length = 30) slug = models.SlugField(max_length = 250, null = False, unique = True) class Office(models.Model): election = models.ForeignKey(Election, on_delete=models.CASCADE, default=None) name = models.CharField(max_length = 30) class Candidate(models.Model): office = models.ForeignKey(Office, on_delete=models.CASCADE, default=None) name = models.CharField(max_length = 30) views.py def poll(request, id): context = { 'election' : Election.objects.get(pk=id), 'off' : Office.objects.all() } return render(request, 'poll.html', context) poll.html {% for office in election.office_set.all %} <div class="text-center"> <h3>{{ office.name }}</h3> {% for candidate in off.candidate_set.all %} <h5><a href="">{{ candidate.name }}</a></h5> {% endfor %} </div> {% endfor %} -
Cannot resize one specific field in Django admin
I’m overriding fields in Django admin like this: class MyPageAdmin(FlatPageAdmin): def formfield_for_dbfield(self, db_field, **kwargs): if db_field.name == 'url': return db_field.formfield(widget=forms.TextInput(attrs={'size': 100})) if db_field.name == 'title': return db_field.formfield(widget=forms.TextInput(attrs={'size': 150})) return super(MyPageAdmin, self).formfield_for_dbfield(db_field, **kwargs) admin.site.unregister(FlatPage) admin.site.register(MyPage, MyPageAdmin) Now, the problem is that for the "Title" field in Django admin, the field width changes just as expected – size attribute is set to 150, but for the URL field, there’s absolutely now change. Yet, the code does run into the specific if statement, so the URL field is definitely there, but for the life of me, I cannot figure out, why only this field is unaffected by the override. Other fields do not suffer this problem (I have other overrides besides the "Title" field, but only the URL is stuck in its original size). -
Django UpdateView CheckboxSelectMultiple - How do I load an object's ManyToMany field in CheckboxSelectMultiple?
My UpdateView draws from a ModelForm where the sport_prefs field loads as CheckboxSelectMultiple. The form loads correctly and submits data to the MemberRecord model successfully. My issue is in the UpdateView even though the sport_prefs field shows up as checkboxes, it does not load the current object sport_prefs field's data. The checkboxes load as blank and while I can select options and it will update and save correctly, I cannot load the sport_prefs data from when it was first created or last updated. models.py class SportOptions(models.Model): sport_name = models.CharField(max_length=200) class MemberRecord(models.Model): name = models.ForeignKey(ContactInfo, on_delete=models.PROTECT) age = models.IntegerField() join_date = models.DateField(default=timezone.now) sport_prefs = models.ManyToManyField(SportOptions) notes = models.TextField(blank=True) author = models.ForeignKey(User, on_delete=models.PROTECT) forms.py class createForm(ModelForm): sport_preference = forms.ModelMultipleChoiceField( queryset=SportOptions.objects.filter(), widget=forms.CheckboxSelectMultiple ) class Meta: model = MemberRecord fields = [ 'name', 'age', 'join_date', 'sport_preference', 'notes' ] My guess is I created a new CheckboxSelectMultiple field and I load the correct options because I draw from the SportOptions model but I do not draw from the specific object's sport_prefs. This shows true when I change the ModelForm 'sport_preference' back to 'sport_prefs' as it loads the data correctly but it does not load as CheckBoxSelectMultiple. I am guessing I need to pass the object … -
Visibility of a Django formview in templates
I've followed the tutorial here to implement a basic search function: https://learndjango.com/tutorials/django-search-tutorial I'd like to extend that tutorial by making the search function visible on the results page, allowing for repeated search. However, when I do this I can't get the search form to show up on the search results page. The search button shows up, but not the field to provide input. Relevant code: home.html: <div name="searchform"> <form action="{% url 'search_results' %}" method="get"> {{ form }} <input type="submit" value="Search"> </form> </div> {% block content %} {% endblock %} search_results.html: {% extends home.html} {% block content %} <h1>Search Results</h1> <ul> {% for city in object_list %} <li> {{ city.name }}, {{ city.state }} </li> {% endfor %} </ul> {% endblock %} Views.py: from django.db.models import Q from django.views.generic import TemplateView, ListView, FormView from .models import City class HomePageView(FormView): template_name = 'home.html' form_class = SearchForm class SearchResultsView(ListView): model = City template_name = 'search_results.html' def get_queryset(self): query = self.request.GET.get('q') object_list = City.objects.filter( Q(name__icontains=query) | Q(state__icontains=query) ) return object_list urls.py: from django.urls import path from .views import HomePageView, SearchResultsView urlpatterns = [ path('search/', SearchResultsView.as_view(), name='search_results'), path('', HomePageView.as_view(), name='home'), ] forms.py: from django import forms class SearchForm(forms.Form): q = forms.CharField(label='', max_length=50, widget=forms.TextInput(attrs={'placeholder': 'Search Here'}) … -
Django Upload button in Bootstrap href without JS
Is there a way to insert a Django FileInput form field in bootstrap href link without using JS. I have something like this: <div class="post-new-tab-nav"> <a href="{{ form.viPicture }}" uk-tooltip="title:Close"> <i class="uil-image"></i> </a> <a href="#"> <i class="uil-user-plus"></i> </a> <a href="#"> <i class="uil-video"></i> </a> </div> The form field that I am trying to insert would be {{ form.viPicture }}. What I intend to achieve would be to trigger the file upload once the href is clicked. Can this be done without using JS? -
My navbar is being overridden by something else and I can't figure out what
so every once in a while, I do collectstatic or something happens where my navbar gets overridden. I can't figure out what's going on. When I would do collectstatic, I would have a staticfiles folder get created, with an admin folder with a bunch of Dif css sheets that were different than mine. Usually when I would delete that folder, things would go back to normal. However, after deleting it, I'm still missing my navbar. My actual links work fine if I manually type them in, but my navbar is getting overridden or something, and I'm not sure why. This problem occurs both locally and on my heroku server. my app https://cupids-corner.herokuapp.com github https://github.com/RezaZandi/Dating-App -

Overridden error message not being displayed in serializer
I have a ListField serializer where if it's empty, it should display the appropriate message: class CreatePostSerializer(serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField( read_only=True, ) topics = serializers.ListField( child=serializers.CharField( max_length=50, error_messages={'max_length': 'Each tag should be no more than 50 characters.'} ), max_length=3, write_only=True, error_messages={'required': 'You need to add at least one tag to your question.'} ) class Meta: model = Question fields = ('user', 'status', 'topics') The error message: You need to add at least one tag to your question. is not being thrown when the list is empty, instead the default error message is thrown: `This field is required."

Accessing JSON data in template in Django
I have a view that retrieves a JSON file like this: json_lang = requests.get('path/to/file.json').json() return render(request, "chat/chatroom.html", {'jsonLang': json.dumps(json_lang)}) Let's say the json file is structured somewhat like this: { "en": { "action.send": "Send", "chat.joined": "joined the chatroom", "chat.left": "left the chatroom", ... } If I try to access one of those strings in a template like this {{ json_lang.en.chat.joined }} I get an empty output. Other methods, like trying to access it like this json_lang.["en"]["chat.joined"] result in an error: TemplateSyntaxError at /chat/ Could not parse the remainder: '["en"]["chat.joined"]' from 'json_lang.["en"]["chat.joined"]' What's the correct method to do this? -

Vue.js (axios) ignoring Django Set-Cookie Response
I am migrating a Django project to Vue.js + DRF, because I need it to be SPA. I went into trouble regarding sessions and csrf cookie which is needed for obvious security reason. Vue app runs on 127.0.0.1:8080 DRF api runs on 127.0.0.1:8000 Response headers used for request (AXIOS): Accept: application/json, text/plain, */* Accept-Encoding: gzip, deflate, br Accept-Language: en,zh-CN;q=0.9,zh;q=0.8,es;q=0.7 Connection: keep-alive Host: 127.0.0.1:8000 Origin: http://127.0.0.1:8080 Referer: http://127.0.0.1:8080/ Sec-Fetch-Dest: empty Sec-Fetch-Mode: cors Sec-Fetch-Site: same-site User-Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36 X-CSRFToken: undefined Response headers from api: Access-Control-Allow-Origin: http://127.0.0.1:8080 Allow: GET, HEAD, OPTIONS Content-Length: 25 Content-Type: application/json Date: Tue, 14 Jul 2020 20:55:13 GMT Server: WSGIServer/0.2 CPython/3.8.2 Set-Cookie: csrftoken=wFeB48cStoHy2hupKZNciGvYKFIlq4Y9QCfzCQ0Qfe5RMdRzolxcYK5MgefvLBcp; expires=Tue, 13 Jul 2021 20:55:13 GMT; Max-Age=31449600; Path=/; SameSite=Lax Vary: Accept, Cookie, Origin X-Content-Type-Options: nosniff X-Frame-Options: DENY Expected outcome: The browser sets the cookie specified by the response headers. I suspect the issue is due to the port being different, I found no solution but to build the Vue in the directory "dist" and Django serves the entry point, but that may not be what I want. -

Django rest framework: Chain nested serializers
I have a DRF API which contains several models that basically form the following hierarchy: Farm -> herd/s -> group/s -> cow/s I've set up the models successfully but I'm not sure how to serialize it. class CowSerializer(serializers.ModelSerializer): class Meta: model = Cow fields = '__all__' class GroupSerializer(serializers.ModelSerializer): cows = CowSerializer(many=True) class Meta: model = Group fields = '__all__' class HerdSerializer(serializers.ModelSerializer): groups = GroupSerializer(many=True) class Meta: model = Herd fields = '__all__' class FarmSerializer(serializers.ModelSerializer): herds = HerdSerializer(many=True) class Meta: model = Farm fields = '__all__' This setup raises the following error: Got AttributeError when attempting to get a value for field `cows` on serializer `GroupSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `Farm` instance. Original exception text was: 'Farm' object has no attribute 'cows'. -

Django: How can I add a looked up field to ListView?
I have a model (Listing below) that contains information about ship sailings. The ports for the sailings are given by the duple of xxxx_country and xxxx_port.

Search QuerySet of Dates Django
I have a QuerySet of dates in my Django project.

I want to enable the functionality so that the user can type "Jan" and all dates in January would remain. Or, if they were to type "J", then all dates in January, June, or July would remain.

These are the Python files I created: admin.py: from django.contrib import admin from django.contrib.auth.admin import UserAdmin as BaseUserAdmin from django.utils.translation import gettext as _ from . import models class UserAdmin(BaseUserAdmin): ordering = ['id'] list_display = ['email', 'name'] fieldsets = ( (None, {'fields': ('email', 'password')}), (_('Personal Info'), {'fields': ('name',)}), ( _('Permissions'), { 'fields': ( 'is_active', 'is_staff', 'is_superuser', ) } ), (_('Important dates'), {'fields': ('last_login',)}), ) add_fieldsets = ( (None, { 'classes': ('wide',), 'fields': ('email', 'password1', 'password2') }), ) admin.site.register(models.User, UserAdmin) models.py: from django.db import models from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, \ PermissionsMixin ... class User(AbstractBaseUser, PermissionsMixin): """Custom user model that supports using email instead of username""" email = models.EmailField(max_length=255, unique=True) name = models.CharField(max_length=255) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) objects = UserManager() USERNAME_FIELD = 'email'
