Django Recaptcha v3 Validate 2 Forms On The Same Allauth HTML Page?
Allauth Code: https://github.com/pennersr/django-allauth/blob/master/allauth/templates/account/email.html https://github.com/pennersr/django-allauth/blob/ee630612f13f4930b7caf64bfc46d6712885621b/allauth/account/forms.py#L418 https://github.com/pennersr/django-allauth/blob/master/allauth/account/views.py#L373 There are 2 forms on the allauth email.html page. I was able to validate one of the forms on that page with recaptcha v3. But how do you validate both of the forms on the page with recaptcha v3? The form that remains to be validated has 3 buttons "make primary", "resend verification" and "remove". Current reCAPTCHA v3 code for only 1 form on that page: <form id="change_email" method="post" action="{% url 'account_email' %}" autocomplete="off" class="add_email"> {% csrf_token %} {{ form.email|as_crispy_field }} <script src="https://www.google.com/recaptcha/api.js?render=PUBLIC_KEY"></script> <script> grecaptcha.ready(function() { var grecaptcha_execute = function(){ grecaptcha.execute('PUBLIC_KEY', {action: "{% url 'account_email' %}"}).then(function(token) { document.querySelectorAll('input.django-recaptcha-hidden-field').forEach(function (value) { value.value = token; }); document.getElementById('change_email').insertAdjacentHTML('afterbegin', '<input type="hidden" name="recaptcha_token" value="' + token + '">'); return token; }) }; grecaptcha_execute() setInterval(grecaptcha_execute, 120000); }); </script> <button name="action_add" class="btn btn-primary form-control" type="submit">{% trans "Add E-mail" %}</button> </form> project_name/app/forms.py: class CaptchaAddEmailForm(AddEmailForm): recaptcha_token = forms.CharField(required=True) def clean(self): super().clean() url = 'https://www.google.com/recaptcha/api/siteverify' params = { 'secret': 'SECRET_KEY', 'response': self.cleaned_data['recaptcha_token'] } response = requests.post(url, params) if response.status_code == requests.codes.ok: print(response.json()['success']) print(response.json()['action']) if response.json()['success'] and response.json()['action'] == '/accounts/email/': print('Captcha valid for user={}'.format(self.cleaned_data.get('email'))) else: print('Captcha valid for user={}'.format(self.cleaned_data.get('email'))) raise forms.ValidationError('ReCAPTCHA is invalid.') … -
Form to show unique values from Model Django
Learning Django.. I have build a setup a below and need your expert advise to make it better.. I created a model, and form on top of it to show the data.. and I have two questions after the code where I need your advise :) Model: class profilestable(models.Model): choices = [ ('Active','Active'), ('Inactive','Inactive') ] Category = models.CharField(max_length=100) SubCategory = models.CharField(max_length=100) product_name = models.CharField(max_length=100) Status = models.ChoiceField(max_length=20,choices=choices) def __str__(self): return self.Category class Userlist(models.Model): User = models.CharField(max_length=100) Categorygroup = models.ForeignKey(profilestable,null=true,on_delete=models.SET_NULL) def __str__(self): return self.User Form: class userprofileform(forms.ModelForm): model = Userlist Fields = ('User','CategoryGroup') def __init__(self,*args,**kwargs): super(userprofileform,self).__init__(*args,**kwargs) Sample data in the profilestable Model: Queries: I want to add the category, subcategory and product name as drop downs to the form however I am not sure how to access each element to show on the form.

Also, is it possible to make it a multi-select and dependent cascading drop downs Request you to please help advise/direct to implement this type of form. Thank you so much. -
Make a Radio Button required in Django Form
I have a form like this: class ReportForm(forms.Form): title = forms.CharField() severity = forms.ChoiceField(label='Severity:', widget=forms.RadioSelect(), choices=SEVERITY_CHOICES, required=True) I am using Crispy forms. If I am on my page that the form is rendering on, and I try to submit without filling anything in, it will tell me title is required. But it doesn't care if severity is filled in or not. I have tried adding required=True to the field but that did not help. -

Group queryset by related field values
I have following models structure: class Chapter: name = ... class Atom: name = ... chapter = FK(Chapter) class Question: title = ... atom = FK(Atom) I want to get all Questions related to Chapter, grouped by Atoms in this chapter. How to do it with many queries I know: atoms = Question.objects.filter(atom__chapter__id=1).values_list("atom", flat=True).distinct() result = {} for atom in atoms: result["atom"] = Question.objects.filter(atom__id=atom) I suppose that it could be done with one query using annotate, Subquery and other Django's staff. Is this possible? -
auto_now_add creates a NotNullViolation in Django unit test
I am trying to set up a unit test for a view that creates 3 objects for use in methods: class TestIssuerSelected(TestCase): @classmethod def setUpTestData(cls): cls.i1 = Issuer(issuer_name='Issuer 1') cls.i2 = Issuer(issuer_name='Issuer 2') cls.i3 = Issuer(issuer_name='Issuer 3') cls.i1.save() cls.i2.save() cls.i3.save() This setUpTestData creates objects from the following model: class Issuer(models.Model): issuer_name = models.CharField() obj_created_datetime = models.DateTimeField( 'Date created', auto_now_add=True, editable=False ) However, it produces the following error: sycopg2.errors.NotNullViolation: null value in column "obj_created_datetime" violates not-null constraint DETAIL: Failing row contains (8, null, Issuer 2). What could be going on here? auto_now_add should not allow a null field, but it is clearly the error occurring. Of note, this error only seems to occur when I run it in sequence with another test before it that sets up the same error. In isolation, this does not occur. How can I debug this? -

Django Download a File after being redirected
Hello I was trying to figure out how to download a file and redirect and someone here suggested I use window.location.href to simulate a link click in the template where the user gets redirected to. At first I struggled with a good way to pass the urls from my views to the template which I got working but then ran into an issue when trying to pass two urls to the templates. I scrapped that idea and settled on just using template filters to return the urls I need which works and you can see below. filters.py @register.filter() def pdf_download_url(value, arg): """ Takes an attendance object and returns the url to download the PDF and Counseling PDF if available. :param value: Attendance object :return: A list with Url for PDF download and URL for Counseling PDF download if there is one """ attendance_download_url = arg + reverse('employee-attendance-download', args=[value.employee.employee_id, value.id]) try: counseling_id = value.counseling.id counseling_download_url = arg + reverse('employee-counseling-download', args=[value.employee.employee_id, counseling_id]) except Counseling.DoesNotExist: counseling_download_url = '' return [attendance_download_url, counseling_download_url] Then in my template I have the following code. account.html {% if download == 'True' and attendance.last.downloaded == False %} window.onload = function(e){ {% for url in attendance.last|pdf_download_url:request.get_host %} window.location.href = '{{ … -
How to make the search function work when the file is inside a model which is inside of another model
I use python and Django 2.2.9 with Django-filter 2.1.0, and I want to add some search function for the website. My database looks like this: Upper is the 'User' database, the downer is the 'Entry' database. Here are what I have in the filter.py: import django_filters from .models import * from django_filters import CharFilter from django.contrib.auth.models import User class UserFilter(django_filters.FilterSet): username = CharFilter(field_name='username', lookup_expr='icontains') class Meta: model = User fields = ('username',) class EntryFilter(django_filters.FilterSet): locations = CharFilter(field_name='locations', lookup_expr='icontains') class Meta: model = Entry fields = ('locations',) # name The search function for the 'username' works well, but the search for the location 'name' does not work. What I think is because the 'username' just in the 'User' model, but the 'name' of the locations is in the 'locations' model which is a model that inside another model called 'Entry'. So, I should try to make it search for something in the 'name' file which inside the 'locations' that inside the 'Entry', but I do not know how to make it. And here is the model.py, I am not sure if I should make any change on it: from __future__ import unicode_literals from djongo import models from django import forms # … -
