Django form validation doesn`t work with invisible reCaptcha
Im trying to implement new invisible reCaptcha with my contact form, but in this case my standart form validation doesnt work. All fields in my form is requierd, however if I type in some incorrect data or miss something - page just reloads with the same data but I will not get standart message with error near field. With reCaptha v2 it works fine. But when trying to use invisible one Im able to press submit button even form is empty. Is there any way to validate form at first? Im using custom decorator to send post request. my settings.py GOOGLE_RECAPTCHA_SECRET_KEY = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' NOCAPTCHA = True decorators.py from functools import wraps from django.conf import settings from django.contrib import messages import requests def check_recaptcha(view_func): @wraps(view_func) def _wrapped_view(request, *args, **kwargs): request.recaptcha_is_valid = None if request.method == 'POST': recaptcha_response = request.POST.get('g-recaptcha-response') data = { 'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY, 'response': recaptcha_response } r = requests.post('https://www.google.com/recaptcha/api/siteverify', data=data) result = r.json() if result['success']: request.recaptcha_is_valid = True else: request.recaptcha_is_valid = False messages.error(request, 'Invalid reCAPTCHA.

dJango data model relations
I am new to Django and trying to understand while working on a project. My system has many tables and wants to know how to model if the relationship of tables are selective. Following is an example : Classes Person, Role and License. Person (many people) Role (A,B) License : Driver’s license I am trying to understand how to use Django model for this. I need License model assigned to Person only if Role B or C assigned. I do not want it if Role A is assigned. License is unique to each person only if role B or C is assigned to Person. For role A, I need to assign blanks to license. -
Django performance with `not in` filter with giant list?
I am currently making a school project where I am building a website that lets you rate nearby restaurants (1-5 stars). The only caveat is that I will show users the restaurants based on location (e.g. closest ones first) and that once they have rated a restaurant, it will never be shown to them again. Currently I have something like this in mind class User(models.Model): username = models.CharField(primary_key=True, max_length=20) location = models.SomeGeoPointField ... class Restaurant(models.Model): title = models.CharField(primary_key=True, max_length=20) location = models.SomeGeoPointField ... class Rating(models.Model): for = models.ForeignKey(User, on_delete=models.CASCADE) from = models.ForeignKey(Restaurant, on_delete=models.CASCADE) rating = models.IntegerField() I am having trouble thinking how the query would look like, and if I used a not in to filter out existing ratings, about the possible performance hit -
Django + uWSGI/nginx inside docker container - ImportError: No module named .wsgi
This an ancient Django (v1.3.7) application that I'm migrating over to a Docker setup. The basic framework comes from this dockerfiles repo. I can get the app running fine using Django's built in dev server (./manage.py runserver), but I'd like to have this served using uWSGI/Nginx in production. I can get uwsgi to run without errors when I call it from a bash prompt within the the container like so: uwsgi --http :8000 --wsgi-file /home/docker/code/siteweb/glrimon.wsgi However, when I try to import my wsgi file from the Django shell I get the same import error.

python if elif else only returning first output without using logic
I have an if elif else block that is only producing output for the if statement even if it should return the other conditions. Even if I change the order of the conditions it always returns the first one. My code is as shown below: for customer in queryset: if feat_list() < 12: customer.Service_Level = Service.objects.get(service_name = 'Silver Package') silver_customers.append(customer.Name) elif 11 < feat_list() <= 15: customer.Service_Level = Service.objects.get(service_name = 'Gold Package') gold_customers.append(customer.Name) else: customer.Service_Level = Service.object.get(service_name = "Platinum Package") platinum_customers.append(customer.name) customer.save() How can I change these statements so that it uses logic not the order? -
Django: Launch a server-side computation and dynamically update the client
I am creating a web application with Django (back end) and JavaScript (front end). The main scenario is the following: a client asks the server to train a neural network (which can take quite a lot: seconds or even minutes, sometimes). Immediately after sending the request, the client shows to the user how the training session is going; it does so by retrieving and displaying the training error, which is actually just a number. For training the network I made this function, which I implemented as a generator: def train(network, trainset): # [setup variables...] while (current_error > target_error): # [continue to train the network...] # [update current_error...] yield current_error On the front end (a simple HTML page) I have a JS script for retrieving data dynamically from a Django view. My Django view goes something like this: def getError(request): # ... generator = train(net, dataset) return StreamingHttpResponse(generator) At the moment I can retrieve the data with an AJAX call but I always have to wait for the server to train the whole neural network before I can see the training errors. My problem is that I would like the user to view the error updates while the server is training … -
Django multi model form, save or update on one model
I have 2 models in 1 form. in this form data can be changed. On 1 model (Sloep_core) there will onle be updates. the other model (Sloep_gegevens) will only do updates, but if the value 'sloepnaam' changed in the form the record must be a insert and not a update.

Datetime On Django on models?
So I just wanna ask if there is a documentation on the datatype for the Django or you can give me the specific datatype to get a datetime field on models.

Django SMTP EmailBackend not working
I'm trying to send email through Django with the default SMTP backend. I configured my settings: EMAIL_HOST = 'mail.mydomain.nl' EMAIL_HOST_USER = 'myusername' EMAIL_PASSWORD = 'mypassword' EMAIL_PORT = 587 EMAIL_USE_TLS = True This is my company's own email server. When I try manage.py sendtestemail or send_mail in a view I keep getting the following error: smtplib.SMTPRecipientsRefused: {'personalemail@gmail.com': (554, b'5.7.1 <52D95A25.cm-11-1b.dynamic.ziggo.nl[X.X.X.X]>: Client host rejected: Access denied')} I made this small script to test sending from pure Python and it works fine: import smtplib sender = 'me@mydomain.nl' receivers = ['personalemail@gmail.com'] message = 'This script works.' try: smtpObj = smtplib.SMTP('mail.mydomain.nl', 587) smtpObj.login('username', 'password') smtpObj.sendmail(sender, receivers, message) print('Successfully sent email') except Exception as e: print('Error unable to send email {0}'.format(e)) Is there something in Django's SMTP EmailBackend that I am not aware of that could be causing the problem?

Django: cretae new object with unique order
I have a simplified model: class Example(models.Model): name = models.CharField(max_length=255, blank=False, null=False) order = models.PositiveIntegerField(blank=False, null=False, unique=True) class Meta: ordering = ['order'] How I can create a new object with existing order number? If I create a new object with an order number 6 for example, then previous 6 and higher orders should have their order number increased by one (7, 8, etc.). Another question is how I can reorder existing objects? Ideally, I could do it by drag and drop in admin but it should be also possible by typing new order number directly. I have initially thousands of objects and reasonable maximum I can think of now should be less than 100,000. Normally I add new objects programmatically from JSON file and some individual changes can be done in admin. I already tried to implement this with django-admin-sortable but no success so far. Also, I'm not sure if it can handle the case of programmatical insertion. -
passing json var in leaflet "on()" methode
I'm working (with Django framwork) on a map with the leaflet library, I want to show some text in a div when I click on a marker. I've made a JS function to create a div with some text in it: function create_div(text): { div = document.createElement(div); div.id = 'article'; div.textContent = text; document.body.appendChild(div); } and then I call this function in the "on" methode given by leaflet because I want to call it when I click on a marker : var articles = {{ list_json | safe }}; for (var i = 0; i < {{ nb_of_articles | safe }}; i++) { var text = articles[i].fields.text; //I put the text of the i-th marker in text. var lat = articles[i].fields.lat; var lon = articles[i].fields.lon; var marker = L.circleMarker([lat,lon]); marker.on('click', function(e) {create_div(text);} ); marker.addTo(mymap); } It kinda work but it put the text of the last object in all the div associate with my marker. For example if I have article[0].fields.text = "hello" article[1].fields.text = "world" I get "world" in the divs, regardless of the marker I click on. I would like "hello" in the div when I clik on the first marker, and "world" in the div when I … -

Django returns 403 error on POST request with Fetch
I have a graphql server implemented using graphene-django. I can make queries to it using jquery like this: function allIngredients() { return 'query{allProducts{edges{node{name}}}}' } var query = allIngredients(); $.ajaxSetup({ data: {csrfmiddlewaretoken: '{{ csrf_token }}' }, }); $.post("/graphql", {query: query}, function(response) { console.log(response); }) However, when I try this call with Fetch, I get a 403, because of the CORS issue. I solved the same problem in jQuery by adding ajaxSetup... before the call. Looking at the docs fetch('/graphql', { method: "POST", headers: { 'Content-Type': 'application/json' }, credentials: 'include', body: JSON.stringify({ csrfmiddlewaretoken: '{{ csrf_token }}', query:`{allProducts{ edges{ node{ id name orderPrice sellPrice } } }`}) } ) .then(function(response) { if (response.status >= 400) { throw new Error("Bad response from server"); } return response.json(); }) I tried adding csrfmiddlewaretoken to the body in the similar way as I did in jQuery example, no luck. I tried adding credentials: 'include' as [the docs say][2], again no luck. I tried with credentials: 'same-origin' and combining this options differently, again the same result. Web is unusually quiet about this, what am I doing wrong? -

My current path to my project looks like this: '/Users/user/Documents/Python/Django Projects/ProjectName/' I want to change the project path to: '/Users/user/Documents/Python/Django_Projects/ProjectName/' When I do this I get the following error message: OSError at / [Errno 2] No such file or directory: '/Users/user/Documents/Python/Django Projects/ProjectName/assets' In my settings.py file I have: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) STATICFILES_DIRS = (os.path.join(BASE_DIR, 'assets'), ) In the request META the PWD value is unchanged: PWD '/Users/user/Documents/Python/Django Projects/ProjectName' I'm fairly new to programming so I apologise for asking such a simple question, but any help would be greatly appreciated. Thanks
