Django DataError in /register/ 'interger out of range'
i'm trying to make a custom registration system with django, but when i submit my registeration form, i get a DataError at /register/, 'integer out of range'. What could be the problem Django says the error is from this file "forms.py" P.S; im using postgres database my code: from django import forms from django.conf import settings from .models import recordBuddyUser from django.views.generic import CreateView from django.core.exceptions import ValidationError # from django.contrib.auth.forms import UserCreationForm class RegisterForm(forms.ModelForm): companyname = forms.CharField(widget=forms.TextInput( attrs={ 'type': 'text', 'name': 'company-nam', 'placeholder': 'company Name', 'id': 'exampleInputcompanyName', 'class': 'form-control rounded-pill btn-user p-4 form-control-user' } ) ) companyadministrator = forms.CharField(widget=forms.TextInput( attrs={ 'type': 'text', 'name': 'administrator', 'id': 'exampleAdminName', 'placeholder': 'company Admin', 'class': 'form-control rounded-pill btn-user p-4 form-control-user' } ) ) companyphone = forms.IntegerField(widget=forms.NumberInput( attrs={ 'maxlenght': '15', 'type': 'number', 'name': 'companyphonenumber', 'placeholder': 'company Phone', 'id': 'examplecompanyPhoneNumber', 'class': 'form-control rounded-pill btn-user p-4 form-control-user' } ) ) companyemail = forms.CharField(widget=forms.EmailInput( attrs={ 'type': 'email', 'name': 'company-email', 'id': 'exampleInputEmail', 'placeholder': 'Email Address', 'class': 'form-control rounded-pill btn-user p-4 form-control-user' } ) ) companypassword = forms.CharField(widget=forms.PasswordInput( attrs={ 'type': 'password', 'name': 'password', 'placeholder': 'Password', 'id': 'exampleInputPassword', 'class': 'form-control rounded-pill btn-user p-4 form-control-user' } ) ) companypasswordconfirm = forms.CharField(widget=forms.PasswordInput( attrs={ 'type': 'password', 'name': 'confirm-password', 'id': 'exampleRepeatPassword', 'placeholder': 'Repeat Password', 'class': … -

Full media absolute paths with graphene-django
I'm currently switching from using DRF to django-graphene while using boto3 and s3 for media content. When using DRF, the file field would come back with the full path for the media inside of the s3 bucket. However, graphene-django file fields are only returning relative paths. For instance with DRF a file field would come back with it's full url like: https://bucket.s3.amazonaws.com/logos/logos_2019-11-07_172356.1808000000.png But with graphene-django it's coming back as: /logos/logos_2019-11-07_172356.1808000000.png Is there a middle where that needs to be added? Or do I need to create my own scaler to deal with this? I'm very new to graphene-django and graphql in general. So any help is very much appreciated. -
Django Nested Admin validation of nested inlines from parent forms
What I'm trying to do is assert the start_date of the child form is after the start_date of the parent form. For example, if I have the following models: class Parent(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) starts_at = models.DateTimeField(blank=True, null=True) class Child(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) parent = models.ForeignKey(Parent, on_delete=models.CASCADE, related_name='children') starts_at = models.DateTimeField(null=True, blank=True) And admin forms setup like: class ChildInline(nested_admin.NestedTabularInline): model = models.Child extra = 0 @admin.register(models.Parent) class ParentAdmin(nested_admin.NestedModelAdmin): inlines = [ChildInline] How would I validate the child based on the parent (or vice-versa)? So far I've explored: Form.clean() - but this doesn't include the child/parent instances. Formset.clean() - but despite making formsets it appears that django-nested-admin ignores them and their clean methods are never used. Has anyone found a solution for this kind of issue? -
Display Database image in django
My database images get deleted from Heroku but the logo is not deleted. I use static to display the logo in this way => <img src="{% static 'img/techshelta_logo.png' %}"> but my database images are displayed without using static => <img src="{{ object.image.url }}" class="img-fluid" alt="object.title">.

Using Django BooleanField to screen filter and screen job applicants
I am working on a job portal where applicants can apply for a role and I can easily screen them based on the fields they filled and the information they give. I have three models Job, Apply, Screen.

Change form output from Django Template
I have a form: class InspectionReportForm(forms.ModelForm): class Meta: model = InspectionReport fields = ('Date', 'Comment', 'Signature') labels = {"Date": "Date (YYYY-MM-DD)"} def __init__(self, *args, **kwargs): super(InspectionReportForm, self).__init__(*args, **kwargs) self.fields["Comment"].widget = forms.HiddenInput() self.fields["Date"].widget = forms.HiddenInput() self.fields["Signature"].widget = forms.HiddenInput() Which stores a report, in addition to the date and who wrote it. In the case of a generic "Pass" or "Fail" report. I want a generic comment in the report, so this would be auto-filled, which is why I have hidden this field. Date and Signature will be taken from the date of submission and the signature will be the logged in user. So mostly all auto-filled. However I have a "maybe" option which prompts the user for a comment and submits that instead of the generic ones. My question is how do I change the comment value of the form from the HTML Template/Javascript stage of my project? My current code is as follows: <form method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <center><button type="button" id="pass">Pass</button> <button type="button" id="fail">Fail</button> <button type="button" id="check" class="collapsible">Check</button> <div class="content"> Comment: <input type="text" name ="comments"> <button id="submitCheck">Submit</button> </div> </center> The Check button is just a collapsible container that has an input box and a submit button … -
How to reliably run custom code when related (ForeignKey) objects change
In a simple ForeignKey relation, I want to run specific code when one of the related object is modified. Here a schematic code : class Car(models.Model): pass class Wheel(models.Model): car = models.ForeignKey('Car', on_delete=models.CASCADE, related_name='wheels', null=True) def save(self, *args, **kwargs): super().save(*args, **kwargs) my_custom_code() According to django's documentation, the reverse related manager method .add perform the save in database using update() instead of save() by default. (idem for .remove, etc...) So in the below code, the my_custom_code isn't called when using .add: car = Car.objects.create() wheel = Wheel.objects.create() # ok my_custom_code called here car.wheels.add(wheel) # not called here because django use "update mechanism" which do not use save method We need to indicate bulk=False to add method in order to force using save method. car.wheels.add(wheel, bulk=False) # ok my_custom_code called here This is a problem for me as it is important that the my_custom_code is called when any of the related objects is modified. If someone forgot to indicate bulk=False, it will generate inconsistent data. There is a signal for this case ? (like m2m_changed signal) There is a way to force bulk=False for all methods of a ForeignKey relation ? Thanks for your help. Why I need this ? My X … -
Correct implementation of UserPassesTestMixin or AccessMixin in class based view
When using class-based views, you can use the UserPassesTestMixin in the following way (docs): from django.contrib.auth.mixins import UserPassesTestMixin class MyView(UserPassesTestMixin, View): def test_func(self): return self.request.user.email.endswith('@example.com') The docs also state: Furthermore, you can set any of the parameters of AccessMixin to customize the handling of unauthorized users However, no example of the syntax is provided as to how to do this. For example, how would I set raise_exception and permission_denied_message so authenticated users get an exception error and not a 403? This does not work, as users are still returned a 403 error: class MyView(UserPassesTestMixin, View): raise_exception = True permission_denied_message = 'You have been denied' def test_func(self): return self.request.user.email.endswith('@example.com') -

Serve django static files from s3, without allowing server to write to s3
I am trying to server django statics from s3. I've googled it, and all of the solutions involve django-storages and boto3 libraries, allowing djangos collectstatic function to upload the statics to s3, and then serve them. Instead, I would like to upload statics separately (manually), and just allow django to point to them. What is the minimum configuration to do this? -
How to programmatically upload local file as Django model field?
I'm having troubles trying to upload files to FileField from local path. I have correctly configurred CDN backend in S3 bucket and use it as PrivateMediaStorage for one of my model fields: class MyModel(models.Model): some_file = models.FileField(storage=PrivateMediaStorage()) ... With this very simple configuration whenever I'm creating/updating model through django-admin it is saved and file attached as some_file is correctly uploaded to S3 bucket. Yet if I try to create/update model instance programmatically, say through custom manage.py command, model instance itself is created but attachment is never uploaded to CDN. Here's simplified version of code I'm using to upload files: class Command(BaseCommand): help = 'Creates dummy instance for quicker configuration' def handle(self, *args, **options): some_file = os.path.join(os.path.dirname(__file__), '../../../temporary/some_image.png') if not os.path.exists(some_file): raise CommandError(f'File {some_file} does not exist') else: instance, created = MyModel.objects.get_or_create(some_file=some_file) What is missing in my implementation and what needs to be adjusted to allow file uploads from local storage? -
How to access the ajax response of the datatable outside the datatable in django?

But the next key i.e, time_data needs to be used in a div which is outside the datatable. How can i access the contents of time_data in javascript? -

When the user clicks onto one of the notification from the drop down box , i will use a AJAX Post request to modify the boolean field to indicate that that particular instance of the Notification has been read before. here is my code: This is my HTML template: <ul class="dropdown-menu dropdown-menu-right myDropDown"> {%for noti in notifications%} {{noti}} <li> <a href="#" class="top-text-block" id="{{noti.id}}" onClick="return booleanchanger(this.id);"> <div class="top-text-heading">{{noti.object_type}}</div> <p class = 'text-muted'><small>{{noti.time}}</small>></p> <div class="top-text-light">{{noti.message}}</div> </a> </li> {%endfor%} </ul> This is my ajax call : function booleanchanger(clicked_id){ var a = clicked_id $.ajax({ url : "{% url 'read-notification' %}", type : "POST", data : { 'csrfmiddlewaretoken' : "{{ csrf_token }}", 'pk' : a }, success : function(result) { } }); This is my notifications model: class Notifications(models.Model): time = models.DateTimeField(auto_now=True) target = models.ForeignKey(User , on_delete=models.CASCADE) message = models.TextField() object_type = models.CharField(max_length=100) object_url = models.CharField(max_length=500,default = 'test') is_read = models.BooleanField(default=False) This is my view that handles the ajax request: def ReadNotificationView(request): if request.method=='POST' and request.is_ajax(): pk = request.POST.get('pk',False) obj = Notifications.objects.get(pk=pk) obj.if_read = True obj.save() print(obj.if_read) return JsonResponse({'status':'Success', 'is_read': 'changed'}) else: return JsonResponse({'status':'Fail', 'is_read':'not changed'}) this is the url.py: path('notification/update/' , views.ReadNotificationView , name = 'read-notification') … -
