Django model instance not being created upon Formset submission
I have a Formset, where one of the fields is a multi-select checkbox, with the options available being determined by a foreign key relationship (to the business model; the form takes business as an arguement). This works, however upon submission of the Formset, nothing is saved to the database despite a POST request and redirect taking place (I would expect it to create an instance or instances of the Instructors model). My models.py (including only relevant models): class Instructors(models.Model): uid = models.CharField(verbose_name="Unique ID", max_length=255, primary_key=True) business = models.ForeignKey(Business, blank=False, on_delete=models.CASCADE) first_name = models.CharField(verbose_name="First Name", max_length=255, blank=False) surname = models.CharField(verbose_name="Surname", max_length=255, blank=False) activities = models.ManyToManyField(Activity, blank=False) def __str__(self): return str(self.uid) class Business(models.Model): # if is_business on profile model = true, then get access to create Business Profile business_name = models.CharField(verbose_name='Business Name', max_length=255) business_description = models.TextField(verbose_name='Business Description', max_length=500) slug = models.SlugField(verbose_name='Slug', max_length=250, null=True, blank=True, unique=True) business_contact_number = models.CharField(verbose_name='Business Contact Number', max_length=32) business_email = models.EmailField(verbose_name='Business Email') business_profile_image = models.ImageField(verbose_name="Profile Picture", null=True, blank=True, upload_to='business_images/') creation_date = models.DateTimeField(auto_now_add=True) address = models.CharField(verbose_name="Street Address", max_length=100, null=True, blank=True) town = models.CharField(verbose_name="Town/City", max_length=100, null=True, blank=True) county = models.CharField(verbose_name="County", max_length=100, null=True, blank=True) post_code = models.CharField(verbose_name="Post Code", max_length=8, null=True, blank=True) country = models.CharField(verbose_name="Country", max_length=100, null=True, blank=True) longitude = models.CharField(verbose_name="Longitude", max_length=50, null=True, … -

Django: User activation not working properly
I have registration page in my Django project. I can finish the registration just fine, and the console outputs the email with the generated link, but for some reason the user value captured by the views is None? How do I fix this?

Django checkbox input only working in one direction
I have a form with a checkbox on "pregnant". If the profile is not pregnant and goes to the update profile form, checking the box and submitting the form updates the profile. I can see in the dashboard it appears as pregnant now. However, if the profile is pregnant, and goes to update profile, unchecking the checkbox (prepopulated) and submitting, it does nothing! The profile information does not update (it still appears as pregnant in the dashboard). I am puzzled because the form connects to the database (it can update from non-pregnant to pregnant) but not the other way around! What am I missing? :-/ See my code. view: def edit_profile(request): if request.user.is_authenticated: current_user = Account.objects.get(id=request.user.id) form = EditProfileForm(request.POST or None, instance=current_user) if form.is_valid(): form.save() messages.success(request,("Your profile has been updated!")) return redirect('dashboard') return render(request, 'accounts/edit_profile.html',context={'form':form}) # else: messages.success(request,('You must be logged in!')) return redirect('login') html: <div class="flex col col-auto form-group form-check"> <label><input type="checkbox" id="pregnancy" value="Yes" name="pregnancy" {% if form.instance.pregnancy == 'Yes' %} checked {% endif %}> {% trans " Pregnant" %}</label> </div> model: class Account(AbstractBaseUser): .... pregnancy = models.CharField(max_length=10,blank=True, null=True, default='No') -
Unable to save the form in my database in Django
I wanted to practice Django, so I started off by creating a quiz website. However the the form isn't being saved into my database. I created the following models. difficulty_choices=(('easy','easy'),('hard','hard'),('medium','medium')) class Quiz(models.Model): name=models.CharField(max_length=200) topic=models.CharField(max_length=100) number_of_questions=models.IntegerField() difficulty=models.CharField(max_length=100,choices=difficulty_choices) def get_questions(self): return self.questions_set.all()[:self.number_of_questions] class Questions(models.Model): text=models.CharField(max_length=200) quiz=models.ForeignKey(Quiz,on_delete=models.CASCADE) correct=models.CharField(max_length=25) def __str__(self): return str(self.text) def get_answers(self): return self.answers_set.all() class Answers(models.Model): text = models.CharField(max_length=200) question = models.ForeignKey(Questions, on_delete=models.CASCADE) def __str__(self): return f"Question: {self.question.text}, Answer: {self.text}" class UserAnswer(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) question = models.ForeignKey(Questions, on_delete=models.CASCADE) answer = models.ForeignKey(Answers, on_delete=models.CASCADE) selected=models.CharField(max_length=25,blank=True) The text field in 'Answer' model contains the options and text field in 'Question' model contains the question The option for each question is displayed in the form of radio select button.

Can Django forms be used in a custom view?
I'm using a CreateView to create an object then a custom written view to assign and update the values. The problem is I can't get to assign multiple values to a many to many relation. A configuration page looks like this right now: I'm not using forms, everything is inside the template. And I have the problem with the last input, the 'Cut material' checkboxes. Since I don't use a form, it's very tricky to handle that some inputs has only one value and some of them might have multiple values (like 'Cut material'). Right now my view will request the POST data and will try to match each option with it's value, but when it get's to 'Cut material' it will get an error if I select more options. I tried some workaround to insert some hidden inputs to pass into the context more info but I had no success. I guess if I can use forms then I might solve this issue and it will also help with validation. How do you think I can manage to pass correctly the value from 'Cut material' to the view to save it correctly? Also if you would do it with … -

Google authentication MismatchingStateError in django (CSRF Warning - State not equal in request and response)
I have a problem that I have been trying to resolve for the past couple of days. When attempting to handle Google authentication in my Django web app, a MismatchingStateError is encountered at /signup/google/callback/. The issue arises when the Google authentication works correctly upon initial attempts but fails with the mentioned error after multiple tries. Even after logging in and out multiple times, the error persists. This is my first time implementing Google authentication within Django, and I've struggled to find comprehensive guidelines or resources. I'm currently learning about flow handling and recently became aware of potential associated risks. It's important to note that this problem resembles CSRF attacks. It emerges when there's a series of rapid login requests. After this error arises, subsequent logins are blocked. Notably, this issue isn't related to the session ID, as I've attempted to clear it without success. It seems tied to generation, possibly due to how states are managed. See the error here def google_auth(request): # Generate the Google OAuth authorization URL and redirect the user to it authorization_url, state = flow.authorization_url(access_type='offline', include_granted_scopes='true') request.session['oauth_state'] = state return redirect(authorization_url) def google_callback(request): # Exchange the authorization code for a Google OAuth access token. stored_state = … -

Django - two approaches to extending user model wont work together?
I am trying to make my django app require a unique email address when creating the account. When I added (the commented line in the models) the unique email constraint in the model I used to add fields before it just adds another email field instead of altering the original one.

Django: Serpy serializer django model JsonField
I am using serpy to serialize my model, so my model has a JSONField containing list of dict. Here is my model: class Section(models.Model): title = models.CharField(max_length=255, null=False) item_count = models.IntegerField(default=0) # The JSON field contents = models.JSONField(blank=True, null=True) I am trying to use serpy.DictSerializer to serialize the contents field but it results in empty dict {} . This is my serializer: class SectionSerializer(serpy.Serializer): title = serpy.StrField() item_count = serpy.IntField() data = serpy.MethodField() def get_data(self, obj): return serpy.DictSerializer(obj.contents, many=True).data As contents is a list of dicts, I have used many=True, But still it is not helping. -
What does this symbol mean "[...]" in docstrings?
I've seen this multiple times now in different python documents. For example: python code The above is from a website that I just saw today and the rest is code written in Django. I see this symbol being regularly used in different documentations. -
Alpine.js x-bind not applying after an HTMX swap
I have an element that is in the initial page load and updates after form post through an HTMX out of bounds swap. On initial load the x-bind formats as expected. After the swap the values from the swapped element display as expected using x-text. The x-bind always fails to apply the formatting that should trigger when staffCount < shiftNeed. When it should apply it quickly flickers immediately after the swap but then goes away. Same flicker is not present when it should not apply. Element on initial page load <tr x-data="{ shiftNeed: {{ day_need }} }"> <td class="fw-bold">Day</td> <td class="fw-bold text-center" x-text="shiftNeed"></td> {% for i, val in day_list|zip:day_staffing %} <td> <div id="dayCount{{ i }}" x-data="{ staffCount: {{ val }} }" x-text="staffCount" x-bind:class="{ 'bg-danger': staffCount < shiftNeed }" ></div> </td> {% endfor %} </tr> Partial template swapped in {% include "schedule/components/schedule_shift_button.html" %} <div id="{{ shift.time_of_day_label|lower }}Count{{ shift.day_num }}" class="text-center rounded" hx-swap-oob="true" x-data="{ staffCount: {{ shift.staff_count }}}" x-text="staffCount" x-init="console.log(staffCount < shiftNeed)" x-bind:class="{ 'bg-danger': staffCount < shiftNeed }" ></div> I added logging statements on the x-init to inspect output, console always displays the expected values of staffCount and shiftNeed and evaluates the criteria used in the x-bind as expected.
