Choices not being rendered in template
Working in Django. I've added choices and the necessary field in my model. The choices are well populated in the admin site, but not rendered in the template. I've double checked several times and everything seems right so I don't understand why the choices aren't rendered in the template. Could it be related to the CSS? I'm using materialize. I've added the .input-field class and initialized the select element as per the materialize documentation. Nothing changed. This is my code: model: class Grocery(models.Model): """ Model to create a grocery_list """ CATEGORIES = [("groceries", "Groceries"), ("school", "School"), ("hardware", "Hardware"), ("travel", "Travel"), ("gifts", "Gifts"), ("decoration", "Decoration"), ("lifestyle", "Lifestyle"), ("wishlist", "Wishlist")] name = models.CharField(max_length=500, default='My grocery list') category = models.CharField(max_length=20, choices=CATEGORIES, default='Shopping') form: class GroceryForm(forms.ModelForm): """ Form to create a grocery shopping list """ class Meta: model = Grocery fields = ['name', 'category', 'shop', 'item'] template: {% block title %}Create shopping list{% endblock %} {% block content %} <div class="container row"> <div class="col s10 m8 push-s1 push-m2"> <h1 class="center-align">Create a grocery shopping list</h1> <div class="divider"></div> <div class="input-field section"> <form method="POST"> {% csrf_token %} {{ form.media }} {{ form.as_p }} <button type="submit" class="waves-effect btn">Create list</button> </form> </div> </div> </div> {% endblock %} JS // … -
TinyMCE data setting issue
Actually i am trying setup data in tinyMCE editor. But, before the tinyMCE editor gets its initialization, function which set data in tinyMCE calls. So, when tinyMCE is loaded, it is with null data. Actually in one page i have around 10-12 editors. At first i started directly form data to load into tinyMCE from serverside in python django. But, it generates missing of data in some of the last editors. So, I decided to set data from client side through javascript. But I could not able to handle that my data setting function call, after the initialization of tinyMCE. So, please help to handle missing data in some of editors. -

Formatting form's film with Boostrap and Django
I have a form which is generated by a model in Django made by text area, choice field, toggle field and so on like: class Test(models.Model): workerID = models.CharField(max_length=200, blank=True, null=True) dashboardURL = models.URLField(blank=True) centralinaVecchia = models.BooleanField(default=False) And I've styled the form with class StartWorker(ModelForm): class Meta: model = Test fields = ('testTitle', 'testDescription', 'centralinaVecchia') labels = { "testTitle": _("Titolo"), "testDescription": _("Descrizione"), "centralinaVecchia": _("Centralina Vecchia?"), } widgets = { 'testTitle': forms.TextInput(attrs={'class':'form-control'}), 'testDescription': forms.Textarea(attrs={'class':'form-control'}), 'centralinaVecchia': forms.CheckboxInput(attrs={'class':'form-check-input'}), The issue is that, if every single field is correctly formated one below the other, the check box is located in a weired way (see screenshot) I'm unabel to style it like the rest of the form.

Django:Filter entries of combobox in template to foreign key
I am having trouble to find a solution to a problem of filtering entries of a combobox. Just to make it easy to understand my problem here an ERM of my models: and my Template looks like: Basicly the queryset for this template is resulting of the following code: class EquipmentinLocationAdd(CreateView): model = EquipmentInLocation form_class = EquipmentAddToLocationForm template_name = 'Procure/equipmentinlocation_add.html' def get_success_url(self): return reverse('equipmentinlocation_sys', kwargs={'pk':self.object.Institute_id}) def get_initial(self): qs = Institute.objects.get( id = self.kwargs['pk'] ) initial = {'Institute': qs} return initial Now I need to filter and restrict the entries of the combobox "Lot" only to the lots which belong to the same project as the institute. However, bringing two queries together in one template seems to be a challenge hard to solve. Need your help, please advise!!! -

How to handle NULL for Django DB Function Concat?

Hide HTMX search results after option is selected
I have a search bar I created using HTMX and django forms that displays results correctly. I have a javascript selectOption() function filling the search bar with whatever the selected option is, but I am having trouble with the search results not going away after I select an option. Can this be handled through javascipt? Additionally, the search bar returns random results once I type something and then delete it, leaving it blank. Is there something I could fill into hx-trigger to fix this issue?

How to Deploy a Django App to AWS Amplify using GitHub
I am trying to find a step-by-step guide that would detail the deployment of a django application using aws amplify. Although options like AWS ec2 are available, I would also like to see if a django web app deployment is possible on AWS Amplify. I have found numerous videos and posts on NextJS developers switching over to AWS Amplify as usage fees on Vercel are getting astronomically higher after a certain amount. Would like to ask for any leads to a guide that would deploy a django app on AWS Amplify. Thank you! <3 -
Nginx throws 403 Forbidden eror whenserving js and css files

In Django, how to multiply-aggregate a field?
I want to aggregate a field using multiplication, but apparently Django doesn't have a Product function among its aggregation function. Example of what I want to do # models.py class MyModel(models.Model): ratio = models.DecimalField(...) # views.py mys = MyModel.objects.filter(...).aggregate(cum_ratio=Product(ratio)) How to achieve this? I feel like since Django didn't include a Product function like they did with Sum suggests that it's trivial but I can't put my finger on it. -

Django: How to create custom ModelSerializer from multiple models/tables in mySQL database?
I'm working on a Django project with an already existing mySQL database. I've quickly learned that mySQL lacks the explicit relationships found in postgresSQL databases where you can establish one to one, one to many, many to many relationships. Instead, you typically need to create a whole other table just for relationships. So currently, I have three tables: userpie_users, radar_sites, and userpie_users2radars (table describing the relationships). Table: userpie_users Table: radar_sites Table: userpie_users2radars Just to clarify, let's examine the first row of userpie_users2radars: id: 2, user_id: 78, radar_id: 17 The id: 2 can be ignored but this row specifies that user_id (78) from userpie_users is attached to radar_id(17) from radar_sites. The next row reveals that the same user also is attached to radar_id(4). For my API "GET" endpoint (http://127.0.0.1:8000/api/map/user_id), I want my final JSON body response to be something like this: { "user_id":"123", "last_name":"smith", "first_name":"john", "last_radar":"28", "radars":[["19","Coal Point Reserve UCSB"],["39","Harvey"],["33","Hawaii"]] } The first four fields are in the userpie_users table so this can be easily serialized with ModelSerializer. "last_radar" is cut off in the screenshot but it's there. "radars" however is an array I need to make by grabbing the user_id from the url parameters, looking through each row in userpie_users2radars … -
Django website not working as expected on home url, but eventually works upon consistent retry
so I have this single page application that runs django backend here. It actually has 4 header option: Jobs (the default), competitions, learn, about. When you visit the application, sometimes it fails to load the jobs section. The spinner just keeps spinning, and when you check the console, you will see an error that says VM96:2 Uncaught (in promise) SyntaxError: Unexpected token '<', "<!doctype "... is not valid JSON Now this is very confusing to me because if you keep clicking the Jobs link, it will eventually load the jobs page correctly (or you can keep trying a complete reload of the url, it will eventually load properly). However, the other hyperlinks work. This problem only happens on the job page, which is the homepage nginx configuration server { server_name pythonyard.com www.pythonyard.com *.pythonyard.com; location /static/ { alias /home/kenechukwu_webapp/allpython/backend/static/; } location / { try_files $uri @node; } location @node { proxy_pass http://127.0.0.1:8000; } listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/pythonyard.com/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/pythonyard.com/privkey.pem; # managed by Certbot include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot } server { if ($host = www.pythonyard.com) { return 301 https://$host$request_uri; } # managed by Certbot if … -

Trying to deploy Django project to Heroku I get the following error: python setup.py egg_info did not run successfully. exit code: 1 error in smart_open setup command: 'python_requires' must be a string containing valid version specifiers; Invalid specifier: '>=3.6.*' note: This error originates from a subprocess, and is likely not a problem with pip. error: metadata-generation-failed Tried multiple versions of smart-open and tried removing it from requirements.txt, the invalid specifier is NOT in my requirements.txt (this is: smart-open==4.1.0) or I have tried multiple other versions, all break the build. I’ve tried changing setup tools on Heroku to eg setuptools==40.3.0, no dice (same errors). -
Django app not loading with DisallowedHost error even after adding IP to ALLOWED_HOSTS
I'm facing an issue with my Django web application deployment on an Amazon EC2 instance. The app is running using Gunicorn and Nginx as a reverse proxy. However, when I try to access the app using the public IP address (ipaddress:8000), it's not loading, and I keep getting a "DisallowedHost" error.

Nginx is configured as a reverse proxy with the following settings: nginx Copy code server { listen 80; server_name ipaddress:8000 location / { proxy_pass http://ipaddress:8000 proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } Despite these configurations, the app still does not load, and I receive the following error in my Django logs: css Copy code [2023-08-02 17:28:00 +0000] [#] [INFO] Starting gunicorn 21.2.0 [2023-08-02 17:28:00 +0000] [#] [INFO] Listening at: http://ipaddress:8000 (#) ... DisallowedHost at / Invalid HTTP_HOST header: 'ip address'. You may need to add 'ipaddress' to ALLOWED_HOSTS. It seems like Django is still considering the request host as 'ipaddress', even though I've explicitly added it to ALLOWED_HOSTS. Any …
