Django localhost returns ok but curl localhost returns the 404 error
The localhost of a Django app runs normal on an AWS server like the following: (env) manage.py runserver 0.0.0.0:8000 Performing system checks... System check identified no issues (0 silenced). Django version 2.2, using settings 'xyz.settings' Starting development server at http://0.0.0.0:8000/ Quit the server with CONTROL-C. The curl -i localhost is returning the 404 error. (env) $ curl -i localhost HTTP/1.1 404 Not Found Server: nginx/1.14.0 (Ubuntu) Content-Type: text/html Content-Length: 178 Connection: keep-alive <html> <head><title>404 Not Found</title></head> <body bgcolor="white"> <center><h1>404 Not Found</h1></center> <hr><center>nginx/1.14.0 (Ubuntu)</center> </body> </html> What does this mean? Does it mean the Django app was installed ok but the Nginx is not working properly? What do I check them out? The tech stack is Django/Python/gunicon/Nginx on Ubuntu 18. -
Django value too long for type character varying(50)
I am trying to create a Site object. http://test-ecommerce-project-dev.us-west-1.elasticbeanstalk.com/ And when I try to create a new Site with the above domain, I got this error value too long for type character varying(50) i think this is caused because my domain is too long. But I don't know how to solve it. I thought of overriding Site class, but i don't know how to do it either. Any ideas appreciated. -
account/register not found in django project
I am new to django and started with a basic. The problem is while following a tutorial I created an account app that has a register page. For some reason whenever I am trying to go to my register page, django tells me that it doesn't match any of the paths. below is the given code: accounts app url.py from django.urls import path from . import views urlpatterns = [ path('register', views.register, name="register") ] accounts app's views from django.shortcuts import render def register(request): return render(request, 'register.html') register.html is: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Registeration</title> </head> <body> <form action="register" method = "post"> {% csrf_token %} <input type= "text" name="first_name" placeholder="First Name"><br> <input type= "text" name="last_name" placeholder="Last Name"><br> <input type= "text" name="username" placeholder="UserName"><br> <input type= "text" name="password1" placeholder="Password"><br> <input type= "text" name="password2" placeholder="Verify Password"><br> <input type= "submit"> </form> </head> <body> </body> </html> ``` web_project urls.py ``` from django.contrib import admin from django.urls import include, path from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path("", include('travello.urls')), path('admin/', admin.site.urls), path('accounts/', include('accounts.urls')), ] urlpatterns = urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) the error I am getting is given below: Page not found (404) Request Method: … -
How to create a customized filter search function in Django?
I am trying to create a filter search bar that I can customize. For example, if I type a value into a search bar, then it will query a model and retrieve a list of instances that match the value. For example, here is a view: class StudentListView(FilterView): template_name = "leads/student_list.html" context_object_name = "leads" filterset_class = StudentFilter def get_queryset(self): return Lead.objects.all() and here is my filters.py: class StudentFilter(django_filters.FilterSet): class Meta: model = Lead fields = { 'first_name': ['icontains'], 'email': ['exact'], } Until now, I can only create a filter search bar that can provide a list of instances that match first_name or email(which are fields in the Lead model). However, this does now allow me to do more complicated tasks. Lets say I added time to the filter fields, and I would like to not only filter the Lead model with the time value I submitted, but also other Lead instances that have a time value that is near the one I submitted. Basically, I want something like the def form_valid() used in the views where I can query, calculate, and even alter the values submitted. Moreover, if possible, I would like to create a filter field that is not … -
TypeError while running Python manage.py runserver command
I'm new to Python/Django and trying to launch a virtual environment in this project for the first time.

How do i ensure I have unique ids within a loop in a template
I have the queryset from a formset which is something like this {[Item 1],[Item 2]}. To display them, i loop thru them in the template. But due to the loop, i have warning that my div have same ids. Can anyone suggest what to do? I can just leave it like that if my page purpose is to display the data only. But the page purpose is to view and update the data and correct me if im wrong, the div with identical ids will affect the update to the database. -
How to fix the error: 'This XML file does not appear to have any style information associated with it'
I hosted a small django project on virtual machine on digital ocean. Before I started using digital ocean to serve static files everything worked fine. But immediately I created a storage space and push my static files there the static files are not being served on the webpage, including django admin page (the project pages are showing net::ERR_ABORTED 403 (Forbidden). I have already installed django_storages and boto3. I got some hint as to the possible cause of the problem when I clicked on digital ocean aws bucket url that looks like https://django-space-storage.nyc3.digitaloceanspaces.com. When I cliked on it I got the following error: This XML file does not appear to have any style information associated with it. The document tree is shown below. It seems the browser is rendering my django pages as xml instead of html. I might be wrong with this assumption because I'm finding a hard time trying to understand what is actually going on. My question is, how do I cause the browser to render my django pages as html instead of xml? -
Python script to web page
I’ve done some research about turning a python script that I have written into an HTML web page. My experience with HTML is somewhat limited, but from what I can tell, I would have an HTML file, and would incorporate Django into said HTML file. Is it as simple as putting something in the HTML file like <p> The function call is: <> myFunctionCall() </><> Or is there a lot more to it than that? -

How to make django publish messages to mqtt on views?

Django Admin make field editable for specific user group
Lets say i have two user groups (user, admin) in my application. Both can see the fields of an instance on the admin model. I have a field named "approved" which is a boolean field. The admin should be able to edit this field, but for the user it should be a read-only field. I tried to use the get_readonly_fields method from django, but it doesent seem to work in combination with the list_display and list_editable attributes. My approach looks like this: @admin.register(Component) class ComponentAdmin(admin.ModelAdmin): exclude = ("created_by",) list_display = ( "id", "approved" ) list_editable = ("approved") def get_readonly_fields(self, request, obj=None): if is_admin_or_mod(request): return [] return ["approved"] -
Django - custom getter for 1 field in model
I am writing a model for an external Oracle DB, which I need to pull info from to my project. One of the fields in that Oracle DB is an XMLType, and it hosts large portion of data, which needs to be pulled via .getClobVal() method, instead of querying it straight as it is. I was wondering, if Django supports any sort of custom logic, for Model's specific fields. Something along the lines of a getter for each field, which I could overwrite to query that specific field as XMLType.getClobVal() instead of just XMLType. At the same time, I don`t want to touch the logic for querying the rest of the Model's fields. Any ideas? -

error on calling a django rest framework endpoint from the same server
I have an API endpoint let's say sampleapi.domain.com/api/v1/1 that worked well in development, both locally (127.0.0.1) and online sampleapi-dev.domain.com, but when I call the same endpoint sampleapi.domain.com/api/v1/1 from the server from which the call is being made sampleapi.domain.com, I get json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) which is unusual since the same code works in development and online.

Was it that the single thread was not available to call the API because it was busy loading the page the API is on? If this isn't the reason, what could be the reason? -
