You are using a function as a API view so, It should be mentioned in the method decorator like shown below
from rest_framework.decorators import api_view
#api_view(['POST'])
def feedback_view(request):
.....
your code
.....
Hope it will give you the solution.
more than one HTTP methods can be used like shown here.
#api_view(['POST', 'GET'])

This question already has an answer here:
Django form.errors not showing up in template
(1 answer)
Closed 9 months ago.
So, I was learning Django from a tutorial and came across form validation. The tutor's version had errors pop-up on screen when validation failed but nothing shows up on my form.
Here is my forms.py.
from django import forms
from django.core import validators
def check_for_z(value):
if value[0].lower() != 'z':
raise forms.ValidationError('Name should start with z')
class FormName(forms.Form):
name = forms.CharField(validators = [check_for_z])
email =forms.EmailField()
text = forms.CharField(widget=forms.Textarea)
This is my views.py file.
from django.shortcuts import render
from myformapp import forms
def form_name_view(request):
form = forms.FormName()
if request.method == 'POST':
filled_form = forms.FormName(request.POST)
if filled_form.is_valid():
# print the form data to terminal
print("Validation success")
print('Name: ' + filled_form.cleaned_data['name'])
print('Email: ' + filled_form.cleaned_data['email'])
print('Text: ' + filled_form.cleaned_data['text'])
return render(request, 'myformapp/formpage.html', {'form' : form})
And this is my template for the page.
<!DOCTYPE html>
{% load static %}
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>Form Page</title>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap#3.4.1/dist/css/bootstrap.min.css" integrity="sha384-HSMxcRTRxnN+Bdg0JdbxYKrThecOKuH5zCYotlSAcp1+c8xmyTe9GYg1l9a69psu" crossorigin="anonymous">
</head>
<body>
<div class="container">
<form method="post">
{{form.as_p}}
{% csrf_token %}
<input type="submit" class="btn btn-primary" value="Submit">
</form>
</div>
</body>
</html>
So whenever i enter a name that's not beginning with z i am supposed to get an exception on the screen but nothing shows up. My code is pretty similar to what the tutor is showing on his machine. Can someone point me in the right direction as to what i am doing wrong.
Thanks
Try using ValidationError (from django.forms import ValidationError) instead of forms.ValidationError
I'm fairly new to using the django framework and recently I made a system with it where it submits data to mysql db through a html form. I got it working eventually and everything seemed quite fine, though I noticed a bug where if I refresh the page django stops sending data to mysql, has this ever happened to anyone?
Stuff for reference:
views.py
from django.shortcuts import render
from websiteDB.models import dbInsert
from django.contrib import messages
def insertToDB(request):
if request.method == "POST":
if request.POST.get('uname') and request.POST.get('email') and request.POST.get('message'):
post = dbInsert()
post.uname = request.POST.get('uname')
post.email = request.POST.get('email')
post.message = request.POST.get('message')
post.save()
messages.success(request, "Message sent successfully.")
return render(request, "contact.html")
else:
return render(request, "contact.html")
models.py
from django.db import models
class dbInsert(models.Model):
uname = models.CharField(max_length=100)
email = models.EmailField()

There are no errors in terminal, and the button click also properly sends a POST req:

I'm also new to posting on stackoverflow, tell me if there's something else to improve on in the future when posting.
index.py
from django.http import HttpResponse
from django.shortcuts import render
def page_home(request):
return render(request, 'index.html')
def contact_page(request):
return render(request, 'contact.html')
Thanks in advance.
If you render the contactpage/ URL, then if you submit the form, you will submit it to the contact view, but that view does not handle the data, nor does it create any entry. You must make sure that you post the form to the insertToDB view. You can do this by giving the view a name:
urlpatterns = [
# …,
path('', views.insertToDB, name='insertToDB'),
# …
]
and then specify the endpoint in the form:
<form class="fontmaker" method="post" action="{% insertToDB %}">
<!-- … -->
</form>
In case of a successful POST request, you should also redirect, for example with:
from django.shortcuts import redirect
def insertToDB(request):
if request.method == 'POST':
if request.POST.get('uname') and request.POST.get('email') and request.POST.get('message'):
post = dbInsert.objects.create(
uname = request.POST['uname'],
email = request.POST['email'],
message = request.POST['message']
)
messages.success(request, 'Message sent successfully.')
return redirect('cpage')
return render(request, 'contact.html')
else:
return render(request, 'contact.html')
I would advise to work with Django forms [Django-doc], for example a modelform [Django-doc] to validate and clean form input and remove a lot of boilerplate code.
1.views.py
from django.shortcuts import render
from . models import User
from .forms import Userform
def Home(request):
if request.method == "POST":
form = Userform(request.POST or None,request.FILES or None)
if form.is_valid():
form.save()
else:
form = Userform()
return render(request,"home.html",{"form":form})
def read(request):
read = User.objects.all()
return render(request,"read.html",{"read":read})
2.models.py
from django.db import models
class User(models.Model):
name = models.CharField(max_length=12)

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’m trying to write a web app which accepts a website visitor’s input which is a 12 digit “Chuckee Cheese” membership card number and then redacts the first 8 digits and presents the redacted number. I’ve got my template written and the basic logic inside my app’s views.py. The problem now is that after the user enters his or her card number, Django is not processing the user input properly. Like, the redacted number is not being presented and served in the template as intended.
Here is a pic on imgur showing my website running on my dev server now. As you can see in that pic, in the web address bar Django receives the ‘ccEntry’ GET Request with ‘123456789102’ as user input. So I guess that kind of works. But below the two h1 elements (in lime green), Django should show the card number ‘123456789102’ as well as the redacted card number ‘xxxx xxxx 9102’ but instead it’s blank. What is wrong here? As far as I can tell, I believe the problem involves either the first two functions inside my redactors views.py or the way my app’s urls.py is arranged.
Here is my views.py :
from django.shortcuts import render
# Create your views here.
def redactors(request):
return render(request, 'alls/landings.html')
def home(request):
if 'ccEntry' in request.GET:
number = request.GET['ccEntry']
redacted_num = 'xxxx xxxx {}'.format(number[-4:])
return render(request, 'alls/landings.html', {'number':number, 'redacted_num':redacted_num})
else:
return render(request, 'alls/landings.html')
def results(request):
return render(request, 'alls/landings.html')
Here is my app’s urls.py:
from django.urls import path, include
from . import views
urlpatterns = [
path('home', views.home, name='home'),
path('results', views.results, name='results'),
]
Those are the two scripts where I believe the problem is.
For what it is worth, here are some other related configuration files and scripts that are in play:
Lightly abbreviated alls/landings.html template:
{% load static %}
<!doctype html>
<html lang="en">

<meta charset="utf-8">

<div class="field">{{ number }}</div>
<h3 style="color:lime">Here it is redacted:</h3>
<div class="field">{{ redacted_num }}</div>
<div class="field"><strong>Again? Click here!</strong></div>
</div> <!--- END card-processor -->
<div class="post-content">
{% for post in posts %}

<h4>Publication Date: {{ post.pub_date_preference }}</h4>
<img src="{{ post.image.url }}" class="authors-pic" style="" />
<!-- Body text should go here : -->
<p>{{ post.body|safe }}</p>
{% endfor %}
{% endblock %}
</body>
</html>
Parent urls.py router:
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('posts.urls')),
path('', include('redactors.urls')),
path('', include('counters.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
I believe those are all the relevant files in play. However in case the problem is elsewhere, if you want to see the rest of my source code, here is a static snapshot tagged as v.0.7.0 on my GitHub.
It's also worth noting that I'm not getting a trace back and my server is not crashing so I don't have many leads in terms of searching on Google for other developers resolving similar or related issues.
It seems like the 'form' in landings.html is being submitted to the path with name "posts", But there is no path with this name in your app's urls.py.
Use this <form action="{% url 'home' %}" method="get"> instead of <form action="{% url 'posts' %}" method="get">.
Am Unable to sent the temp_k variable from my views to index.html. I have made a request from weather API and trying to pass it to my html.
Please suggest how we are supposed to send the variable from views to template.
views.py
from django.template.loader import render_to_string
import requests
from django.shortcuts import render
from django.http import HttpResponse
def hello(request):
my_dict = {'insert_me': "From andu.py"}
return render(request, 'mywebapp/index.html', context=my_dict)
def temperature(request):
#zip=requests.form['zip']ss
r=requests.get('http://samples.openweathermap.org/data/2.5/weather?zip=94040,us&appid=b6907d289e10d714a6e88b30761fae22')
json_object=r.json()
my_dict1={'temp_k' :json_object['main']['temp']}
return render(request,'mywebapp/index.html', context=my_dict1)
index.html
<!DOCTYPE html>
{% load staticfiles%}
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Hey</title>
<link rel="stylesheet" href={% static "cs/style.css" %}/>
</head>
<body>
<h1>This is the Header</h1>
<img src="{% static "images/youownme.jpeg" %}" atl="Uh Oh">
<h2> Temperature:{{temp_k}}</h2>
</body>
</html>
I have tried your code and it works fine so you may want to check if you are rendering the right HTML files maybe, i've changed your code to make sure it's working and it is
my_dict1={'temp_k' :json_object['wind']['speed']}
sorry but I cant write a comment yet!
Use render like this :
return render(request,'mywebapp/index.html',{'context':my_dict})
