I am building a blog website where I can upload audio/video files to the database and then run a for loop to output the files in HTML audio/video tags. I have succeeded in saving the files to the database and also output them on the website but for some reason I can't get them to play.
I am still pretty new to Python/Django and I would appreciate it if anybody can help me figure this one out. Thanks in anticipation
Here is my models.py
from django.db import models
class Track(models.Model):
track_title = models.CharField(max_length=250)
track = models.FileField(upload_to='album/')
def __str__(self):
return self.track_title
Here is my index.html
{% load static %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
{% for track in tracks %}
<figure>
<figcaption>Audio</figcaption>
<audio controls>
<source src="{{ track.track.url }}" type="audio/mp3">
</audio>
</figure>
{% endfor %}
This is my views.py
from django.shortcuts import render
from .models import Track
def songView(request):
tracks = Track.objects.all()
context = {
'tracks':tracks
}
return render(request, 'album/index.html', context)
And my urls.py
from django.urls import path
from . import views
app_name = 'album'
urlpatterns = [
path('', views.songView, name='song'),
]

I need help with my code, I'm making a form in django and I can't solve this error.
views.py:
def ferrocarrilFormulario(request):
if request.method =="POST":
miFormulario = ferrocarrilFormulario(request.POST)
print(miFormulario)
if miFormulario.is_valid:
informacion = miFormulario.cleaned_data
ferrocarril = ferrocarril(request.POST["tipo"], request.POST["precio"])
ferrocarril.save()
return render (request, "AppCoder/inicio.html")
Forms.py:
from django import forms
class ferrocarrilFormulario(forms.Form):
tipo= forms.CharField()
precio = forms.IntegerField()

thank you <3
I wanted the form to work after that, but that is not the case.
PS: if I put the request, it generates another error, and in the tutorial it appears without the request.
Thanks again.

i want to add data to django admin using a form but data is not uploading at django admin

Problem is in the action of your form, you have entered the wrong URL in the action
You have to put home URL instead of read/, because you are handling your form submission in your home function so replace your form action by this
<form method="POST" action="{% url 'Home' %}" enctype="multipart/form-data">
{%csrf_token%}
{{form}}
<button type=submit>click to submit</button>
</form>
I have created a project named Test and an app named testing inside this app. I have a model named ModelTesting in the testing app. This model has only one field named prop, which is a CharField of max_length=20. I can insert the items in database without any issue but cannot display them in the homepage. Take a look at my code.
Here is my models.py
from django.db import models
# My Model
class ModelTesting(models.Model):
prop = models.CharField(max_length = 20)
def __str__(self):
return self.prop
Here is my views.py
from django.shortcuts import render
from .models import ModelTesting
# Loads Homepage
def index(request):
all_testing_models = ModelTesting.objects.all()
params = {'all_models': all_testing_models}
return render(request, "index.html", params)
And here is the bootstrap template in which I want to display the items. Also, I have edited the template myself.
<!doctype html>
<html lang="en">

This error has occurred in some other projects as well, so I created this project specifically for this purpose. Please take a look and help me.
Thank You.
You're doing all_models in
params = {'all_models': all_testing_models}
and trying to look for all_testing_models in
{% for test_model in all_testing_mdoels %}
<h3>{{test_model.prop}}</h3>
{% endfor %}
Fix either one to match the other.
You may wish to turn on string_if_invalid to help you catch typos better.

The issue is that you're wrapping the request inside of a RequestContext object, which is incorrect for the render() function.
The render() function will build the RequestContext object for you, so it expects the request and any extra context variables as arguments.
Instead, just pass the request directly to the render() function:
def survey(request):
return render(request, 'wfhApp/survey.html')
I'm trying to get a string out of an ArrayField in my database but it only prints by characters, not the full string. For example, the ArrayField is named words and in the database it shows as {word1, word2, word3} so in the HTML I put {{ object.words.0 }} and { is rendered on the screen.
How can I get it to render word1?
I have added django.contrib.postgres to INSTALLED_APPS.
This is what it looks like in my model:
from django.db import models
from django.contrib.postgres.fields import ArrayField
class WordArr(models.Model):
words = ArrayField(models.CharField(max_length=200, null=True))
I fixed the issue and it was with my database. The ArrayField in my model was previously a CharField that I changed. I thought the migrations were correct however the database was still reading it as a CharField, so the output was the first character of a string. I migrated to a new database and everything worked fine. My code is below for further reference:
models.py
from django.db import models
from django.contrib.postgres.fields import ArrayField
# Create your models here.
class Word(models.Model):
first = models.CharField(max_length=50)
last = models.CharField(max_length=50)
words = ArrayField(models.CharField(max_length=50, null=True))
def __str__(self):
return self.first
views.py
from django.shortcuts import render
from django.views.generic.detail import DetailView
from django.views.generic import CreateView
from .models import Word
# Create your views here.
class ArrayCreateView(CreateView):
model = Word
fields = ['first', 'last']
success_url = '/'
def form_valid(self, form):
w = form.save(commit=False)
random_words = ["word1", "word2", "word3"]
w.words = random_words
return super().form_valid(form)
class ArrayDetailView(DetailView):
model = Word
