I did it before but i dont know what is causing this, everything seems to be fine, so i hope you can help me: here is my models.py: def upload_location(instance, filename): return "uploads/%s/img/%s/" % (instance.id, filename) class CustomUser(AbstractBaseUser, PermissionsMixin): ...... width_field = models.IntegerField(default=0) height_field = models.IntegerField(default=0) photo = models.ImageField( upload_to=upload_location, null=True, blank=True, width_field="width_field", height_field="height_field" ) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] objects = UserManager() Here is my form: class UserConfigurationForm(UserChangeForm): class Meta: model=CustomUser fields = ( 'first_name', 'last_name', 'email', 'phone_number', 'direction', 'password', 'photo', ) Dont pay attention to the other fields apart from ´photo´,those fields works fine. just have the problem with the image My view: def configuration(request): categoria = Clasificacion.objects.filter(existencia=True) templates = Templates.objects.get(isSelected=True) if request.method == 'GET': form = UserConfigurationForm(instance=request.user) else: form = UserConfigurationForm(request.POST or None, request.FILES or None, instance=request.user) if form.is_valid(): form.save() return redirect('myuser:myuser') return render(request, 'myuser/configuration.html', {'form': form, 'categoria':categoria,'templates':templates}) And finally my template (I will include the entire form soyou can see it).. <form method="post" action='' enctype="multipart/form-data"> {%csrf_token%} <div class="col-sm-8 "> <strong>{{form.photo}}</strong></div> <!--FIRST NAME--> <label for="first_name">Nombre</label> <div class="form-group"> <input class= "form-control" type="text" name="first_name" maxlength="20" value="{{user.first_name}}" required> </div> <label for="last_name">Apellidos</label> … -
Display data from a database in a HTML page using django views
I have a problem with creating a view with data from the database. I created a view that should download data from videos (var films) and display them, unstable I only have a blank page. views.py from django.shortcuts import render from django.http import HttpResponse from .models import Films # Create your views here. def index(request): filmy = Films.objects return render(request, 'films/index.html',{'filmy':filmy}) index.html <h1>Films</h1> {% for film in films.all %} {{filmy.summary}} <br> {% endfor %} models.py from django.db import models # Create your models here. class Films(models.Model): image = models.ImageField(upload_to='images/') summary = models.CharField(max_length=200) def __str__(self): return self.summary -

How can I ensure Django CMS initializes app urls?
I'm trying to boot up a Django CMS app. All the app hooks are properly set up and registered. For an example take the NewsHook: class NewsHook(CMSApp): """ A class to hook the News into the django cms """ name = _("News") urls = ["apps.news.urls"] apphook_pool.register(NewsHook) The urls.py of this hook includes the following: urlpatterns = [ # /feed/ url(r'^feed/$', ArticlesFeed(), name='news_feed'), ] And the urls.py of the project (under the settings folder) includes the following relevant lines: admin.autodiscover() urlpatterns = patterns( '', ... # / -> Django CMS url(r'^', include('cms.urls')), ) All this looks normal, right? But when I visit the home page, I get NoReverseMatch error: Not sure what I am doing wrong... Is there a side of this that I'm not seeing? Btw, this app runs well on production, so it doesn't have any bugs as far as I can see. My Specs Django version: 1.8.13 Django CMS version: 3.3.0 Python version: 2.7. -
Accessing property of model instance from list and add them together?
Say I have a model: class Mymodel(models.Model) property = models.IntegerField() Say I have a function: def func(): instance = Mymodel.objects.order_by('?')[0] instance2 = Mymodel.objects.order_by('?')[0] plan = [instance, instance2] return plan I want to use a for loop to add together the integers in the 'property' of the model instance and then output the sum into one of my templates? I have tried the add filter but the problem is the amount of instances it will be adding together are dynamic so I can't simply do myModel.0.property|add:myModel.1.property Thanks in advance. -
Getting live server fixture with Django test not working
I would like to use pytest, pytest-django, and pytest-selenium together to test my Django application functionality. If I start the server manually with python manage.py runserver, and manually input the URL, it works fine. The live_server fixture from pytest-django is supposed to start a server process in the background that I could use, but it's not working. Instead of a passing test, I get "The requested resource was not found on this server." Here are the relevant sections of my files: pytest.ini [pytest] DJANGO_SETTINGS_MODULE = chatsite_api.settings.test addopts = --liveserver localhost:8080 --cov=. --cov-report=html --driver Firefox test_pages.py import pytest def test_homepage(selenium, live_server): selenium.get(live_server.url) assert "Django: the Web framework" in selenium.title And chatsite_api.settings.test.py from .dev import * # NOQA DATABASES = {"default": {"ENGINE": "django.db.backends.sqlite3", "NAME": ":memory:"}} DEBUG = True As I said, the tests run fine when I start the server myself, but the live_server fixture doesn't seem to be doing what it's supposed to. I have verified that the live_server.url is being set according to the addopts line in pytest.ini, but that is as far as I've gotten. -
How to add a DialogFlow chatbot with audio to a Django website?
I'm using Django to develop a website and would like to integrate it with a DialogFlow chatbot. I want to display the conversation and play the speech response. How should I go about implementing that? I have understood that this problem is not trivial. So far I have created a DialogFlow agent and tested it with the Python client library using https://cloud.google.com/dialogflow/docs/detect-intent-tts#detect-intent-tts-python. I researched Django Channels but came to the conclusion that it can't handle the speech part. Tips on the structure and approach to solve this problem and handle the communication would be appreciated. A link to a tutorial or code would be great. I'm quite new to web development and don't have a clear picture of all the available tools yet. -
Python Django Queryset only get month and year from date
I currently use the following code to create the queryset for my Fusioncharts bar chart: dataSourceBar['data'] = [] objects_with_category_id_2 = dashboard_input.objects.filter(service_service_id=3,category_category_id=2) for obj in objects_with_category_id_2: data = {'label': obj.session_start.strftime("%m.%Y"), 'value': obj.input_input_value} dataSourceBar['data'].append(data) I tried to only get the month and year from the session_start, but now it only shows each month and year per date something is filled in. Is there a way in which I can design the queryset that it sums the different values per month (in descending order)? So that the graph only shows three bars: 04.2019, 05.2019 and 06.2019? -

How to build a list of GMT time zone offsets in Django?

How do I get some (custom) user data in my api.py?
I'm not sure how to pass data from two 'nested' models to an endpoint. I want to set up some data related to the user in my Django application. After some googling I found the best way to 'extend' the default user model is to create another model with a OneToOneField pointing to the user. This is how the model looks like: # models.py from django.db import models from django.contrib.auth.models import User class UserData(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) currency = models.CharField(max_length=10, default="USD") budget = models.IntegerField(default=500) showCategories = models.BooleanField(default=True) showLocations = models.BooleanField(default=True) showSources = models.BooleanField(default=True) def __str__(self): return self.user After writing the model, I wrote a new serializer for it: # serializers.py class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'email', 'username') class UserDataSerializer(serializers.ModelSerializer): user = UserSerializer() class Meta: model = UserData fields = ('currency', 'budget', 'showCategories', 'showLocations', 'showSources', 'user') All good so far (I hope). Finally, I've changed my UserAPI to have a serializer_class of UserDataSerializer. This is how it looks right now: # api.py class UserAPI(generics.RetrieveAPIView): permission_classes = [ permissions.IsAuthenticated, ] serializer_class = UserDataSerializer def get_object(self): # I suppose I need to return something else here but I'm not sure what. return self.request When accessing my endpoint … -
django-rest without model post request test from browser
I'm working to have a viewset in django-rest framework that user can post a json to me and I give them back a csv file for downloading. Thus I don't have any model or serializer for that. The endpoint will be like 127.0.0.1:8000/download/ and I registered that endpoint through url(r'^download/$', views.DownloadViewSet.as_view(), {'post': 'download'}, name="CSVDownload"), My question is how can I test the post request through the browser? I don't have any boxes for the post request and can't actually see my api-request through web since it's not registered through router. -

Why Taggit (Django-Tag) won't work once I used Tag.models.all()
I have implemented django-taggit successfully until I was trying to use the mixin to render the tags on a ListView of "PropertyListing" in this example: The console keep telling me: NameError: name 'Tag' is not defined **The PROBLEM comes from the views.py line 4 apparently.

Attaching the logged-in User to object after object creation
I am trying to have a logged in User fill out a form to create a Group. On Group creation, I need the User to automatically be added to the Group. For this problem, we are working with two models - User and Group. User is the default model provided by Django. Group is defined like so: class Group(models.Model): name = models.CharField(max_length=255, unique=True) admins = models.ManyToManyField(User, default=1, related_name='user_username') all_users = models.ManyToManyField(User, default=1) def __str__(self): return self.name def get_absolute_url(self): return reverse('home') def get_admins(self): return ", ".join([u.username for u in self.admins.all()]) def add_admin(self, user): self.admins.add(user) def get_all_users(self): return ", ".join([u.username for u in self.all_users.all()]) def add_user(self, user): self.all_users.add(user) self.save() def is_admin(self, user): if user in self.admins.all(): return True else: return False And the view I'm trying to refactor is: @login_required def user_generated_group(request): if request.method == 'POST': form = GroupForm(request.POST) user = request.user if form.is_valid(): group = Group.objects.create(name=form.cleaned_data['name']) group.add_admin(user) group.add_user(user) group.save() return HttpResponseRedirect(reverse('home')) else: form = GroupForm() context = { 'form': form, 'type': 'group', 'sidebar': Sidebar(request), } return render(request, 'form.html', context) The goal is to utilize Django's built-in CreateView.

How to get the .env file into the remote host server
Quick question how to get the .env conf file into the server. I have three settings file in my project base, development, production. I think testing and staging is an overkill It is encouraged to put .env in .gitignore file. so it won't be included in version control. in Heroku, it is easy to set the environment variable in the settings tab. what about other hosting services without such a feature? since I push to my repository and pull from the server, How I am I suppose to get the API keys stored in the .env since it will ignore it (it's in gitignore) file? should I create in the server? or is there a way it is done? Newbie question I know. -

Sending multiple checkbox answers within form by ajax
I am trying to send form data to my Django application using ajax. I am using this JQuery which works fine (to a point) $ (function () { $('#filtersForm :checkbox').change(function() { $.ajax({ url : "/ajax-search/", data: $("#filtersForm").serialize(), type : "GET", success : function(html) { console.log("success"); replaceJobs(html); }.bind(this), error : function(xhr,errmsg,err) { console.log("error"); }.bind(this) }); }) }) There are a number of checkboxes in the form using a forms.ModelMultipleChoiceField. My django form looks like: class FilterSearchForm(forms.Form): job_location = forms.ModelChoiceField( queryset=OfficeBase.objects.filter(name="Remote"), widget = FilterCheckboxSelectMultiple, required=False) job_type = forms.ModelMultipleChoiceField( queryset=Employment.objects.filter(active=True), widget = FilterCheckboxSelectMultiple, required=False) job_category = forms.ModelMultipleChoiceField( queryset=Category.objects.filter(active=True), widget = FilterCheckboxSelectMultiple, required=False) Which produces html like: <ul class="list-unstyled list-increase-spacing"> <span class="form-checkbox"> <li> <input id="id_job_category_0" type="checkbox" name="job_category" value="1"/> <label id="label-id_job_category_0" for="id_job_category_0"> Category 1</label> </li> </span> <span class="form-checkbox"> <li> <input id="id_job_category_1" type="checkbox" name="job_category" value="2"/> <label id="label-id_job_category_1" for="id_job_category_1"> Category 2</label> </li> </span> </ul> When multiple boxes are checked, I am only getting the last one in my view. I am getting the items usingfor key, value in self.request.GET.items(): How do I ensure I get all checked items? -
