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. -

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. -
Why when I create an enviroment with anaconda in Visual Studio Code and I try to activate it, shows me an error
I try to activate the env that I already created and everything fine, but when I tried the command "conda activate whynotdata" it shows me this error: PROGRAMACION\Data_base_whynot> conda activate whynotdata usage: conda-script.py [-h] [--no-plugins] [-V] COMMAND ... conda-script.py: error: argument COMMAND: invalid choice: 'activate' (choose from 'clean', 'compare', 'config', 'create', 'info', 'init', 'install', 'list', 'notices', 'package', 'remove', 'uninstall', 'rename', 'run', 'search', 'update', 'upgrade', 'build', 'convert', 'debug', 'develop', 'doctor', 'index', 'inspect', 'metapackage', 'render', 'skeleton', 'verify', 'token', 'pack', 'server', 'env', 'content-trust', 'repo') When I create it with the anaconda prompt everything works fine but in Visual Studio Code I can't complete it, and I want to create my env on the folder that I have on Visual Studio, I am a begginer in the back-end, I am of autodidact learning. Thank you I am trying to create an env on a folder that I create and then install django, I want to use Anaconda to create the project but it didn't work and is rare because on the config of my sistem I added the path to the environments of windows, of the anaconda3 and anaconda3\scripts -
Django cap a DateField value in the database
Sorry I am very new to Django. I have date of birth (DOB) as a field in my model. I use the DOB to calculate the age and get some values from other dataset. class Account(AbstractBaseUser): first_name = models.CharField(max_length=50) dob = models.DateField(blank=True, null=True) The age cannot be higher than 120 years so I raise a ValidationError with the registration and update profile forms whenever they enter a DOB of more than 120 years ago. def clean(self): cleaned_data = super(RegistrationForm, self).clean() dob = self.cleaned_data.get('dob') age = (date.today() - dob).days / 365 if age > 120: raise forms.ValidationError('Sorry but profiles cannot be registered with more than 120 years old due to scientific data unavailability.') elif age < 0: raise forms.ValidationError('Date of birth is in the future. Please enter valid birth date.') However, what if they register as born 119 years ago. In 1 or 2 years, the age would be 121 and my code will fail. Is there a way to always cap the value of the DOB in my database so the DOB is always maximum 120 years old? I checked the documentation for DateField but there is no reference to MinValueValidator as in the case of IntegerField. -

Custom Django Admin Page/View
Basically I'm trying to create a custom admin web page, like a custom a view. Ideally what I want is something where like once you log in to the admin page, there would be a link somewhere like under the list of models that would redirect you to this admin center. I have a somewhat working version currently, but I would like to have it redirect to a new URL like “ /admin/social/edit/ “ instead and not just render context into the template. I’ve done a ton of googling and I just keep coming across things like “custom admin actions” which is not per se what I’m looking to do. Any help is appreciated. Thank you. -

How can I set group permissions that filter pages according to their owners in Wagtail
I am working on a blog with Wagtail and would like to give users access to create their own content in the Wagtail admin. I would like users to be able to log into the Wagtail admin, but only have access to content that they have created themselves. I have tried to generate permissions by group, however there is no default option to limit content by author, so if I give add, edit and publish permissions, a user could edit content created by other users and could unpublish or even delete that content. I would like to know if there is a way to modify the queryset of pages that appear in the Wagtail admin for a specific user. I don't have much experience with Wagtail. So far I have seen some possible solutions but none have seemed viable or adequate. For example, there are some posts here where they propose to create a Parent page for each user, but then you would have to create a group for each user, which doesn't seem like an efficient way to do it. I appreciate any help or suggestions. Here I share some of the relevant code: class BlogIndexPage(Page): max_count = 1 … -

using mongodb with motor driver and django
i'm creating an App, using async driver(motor) for mongodb. I have a telegram bot app and django framework app. I want my telegram and web apps use same database. When i try to create User via integrated CreateView class, by default django uses it's standart auth processing and adds user to its default databases(sqlite, postgre etc.) But i'd like to use mongodb and use it asyncronous(as i understood djongo is syncronous driver) the ways I see to solve this: 1) separate users' auth data(to standart database) and other data, that'll be fetched and overwritten frequently(to mongo). 2) use standart view(e.g. TemplateView, FormView) and my own form, write MyOwnUserClass with hashing and all necessary methods. Shortly I want to use instruments of Django with mongodb, how can I reach that? Well don't know if this is needed here, a piece of my current code: forms.py: class RegisterUserForm(UserCreationForm): username = forms.CharField email = forms.EmailField password = forms.PasswordInput password_confirm = forms.PasswordInput telegram = forms.CharField(required=False) views.py: class Register(CreateView): template_name = 'AIsite/register.html' form_class = RegisterUserForm success_url = reverse_lazy('login-user') -

Heroku can't find styles.css
Trying to deploy a Django app to Heroku for the first time. When I view the app using Django, everything shows up correctly, but when I run it on Heroku, pieces of the UI are missing. I'm not too familiar with the frontend - this was a group project and I was working on backend - and my team isn't willing to help with deployment, so I'm unable to diagnose any frontend issues. Looking at the Heroku logs, I get this error "Not Found: /static/styles.css" - but there is a styles.css file under static. Does anyone know where the root problem might lie? Under settings.py I have specified this STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [os.path.join(BASE_DIR, 'staticfiles')] All functionalities work as expected, I think it has something to do with the base.html file - but this is just a stab in the dark. An example of what it's meant to look like, compared to what it looks like on Heroku. -

What would be a better solution for storing data in a Django model?
Could you please give me a piece of advice? Context: I have a Django project in which each user stores many different variables linked to his profile. I created a model called Snapshot, that has a foreign key of user. Single user can have multiple Snapshots linked to his User instance, but only the latest one (by its ID, pk) is editable. Any other ones might be used to revert to past setup only. Typical use case: User modifies his setup stored in his latest Snapshot using API endpoints. Each function that an endpoint call has to query the latest Snapshot owned by user that called the function. Then it modifies some of the variables in the Snapshot and saves it. Once everything's done user approves the setup and the Snapshot is being duplicated. Now the new instance becomes the latest. Question: Is it a good idea to query the latest Snapshot this many times in each function? Wouldn't it be a good idea to link the latest Snapshot one-to-one with User, so that it's always available as User.latest_snapshot? This latest_snapshot would be automatically re-linked to User once user approves setup, thus creating a new Snapshot.
