Why the html custom form is not working django

I have a contact page with a simple form.
Here is views.py:
def contact_view(request):
if request.method == 'GET':
form = ContactForm()
else:
form = ContactForm(request.POST)
if form.is_valid():
subject = form.cleaned_data['subject']
from_email = form.cleaned_data['from_email']
message = form.cleaned_data['message']
try:
send_mail(subject, message, from_email, settings.ADMIN_EMAILS)
except BadHeaderError:
return HttpResponse('Invalid header found.')
return redirect('success')
return render(request, "base/contact.html", {'form': form})
def success_view(request):
return HttpResponse('Success! Thank you for your message.')
this is contact.html:
{% block content%}
<main class="page contact-page">
<section class="portfolio-block contact">
<div class="container">
<div class="heading">
<h2>Contact me</h2>
</div>
<form method="post">
{% csrf_token %}
<div class="mb-3"><label class="form-label" for="name">Your Name</label><input class="form-control item" type="text" id="name"></div>
<div class="mb-3"><label class="form-label" for="subject">Subject</label><input class="form-control item" type="text" id="subject"></div>
<div class="mb-3"><label class="form-label" for="email">Email</label><input class="form-control item" type="email" id="email"></div>
<div class="mb-3"><label class="form-label" for="message">Message</label><textarea class="form-control item" id="message"></textarea></div>
<div class="mb-3"><button class="btn btn-primary btn-lg d-block w-100" type="submit" value="submit">Submit Form</button></div>
</form>
</div>
</section>
</main>
{% endblock %}
When I use form.as_p it works very well but when I use this template it is not working
it only shows in the terminal that a post request was made.

The html looping syntax of form is following, where we have access to specific field, field.label ,non_field_errors as well as particular field errors.
In your case you can use in this way:
contact.html
{% block content%}
<main class="page contact-page">
<section class="portfolio-block contact">
<div class="container">
<div class="heading">
<h2>Contact me</h2>
</div>
<form method="POST" novalidate>
{% csrf_token %}
{% if form.non_field_errors %}
{% for error in form.non_field_errors %}
<div>
{{error}}
</div>
{% endfor %}
{% endif %}
{% for field in form %}
<p>{{field.label_tag}} {{field}}</p>
<br>
{% for error in field.errors %}
<span>{{error}}</span>
{% endfor %}
{% endfor %}
<input type="submit" value="Save">
</form>
</div>
</section>
</main>
{% endblock %}
You can use it as above it will work perfectly with your existing views, as you said it is working with form.as_p.
If you give only form.as_p, it will render form fields in <p> tag of html, you can see through Ctrl+U of view page source,there we cannot have more control over form.
Your question -- How can i use bootstrap's classes in django's form?
Answer - You can set through widget in your form's fileds. for example:
class MyForm(forms.Form):
name=forms.CharField(widget=forms.TextInput(attrs={'class':'form-control'}))
In the above way, you can set it to every field.

Django 2 form in modal

Im tries to open in Django the user edit form in Bootstrap modal. But the form is empty, only the save button is shown. But I don't understand how I can make the connection. If I call the edit page directly, then I can edit the user
127.0.0.1:8000/account/edit/
index.html, includes the referral to the form
{% extends 'base.html' %}
{% block head %}

{% block body %}

fields = (

'last_name'
)
Im using:
Python 3.6.3
Django 2.0.7
Windows 8.1
Bootstrap 3.3.6
JQuery 1.12.0

I think that variable form doesn't exist and you use in template just user_form not form variable
{% include "account/edit_profile.html" with form=form %}
Try use it:
{% include "account/edit_profile.html" with user_form=user_form %}

Maybe you could try the code I wrote and you can find it at django-bootstrap-modal-forms. You will be able to bind your form to the modal and all of the validation stuff will work out of the box.
You will create a trigger element opening the modal
Your selected form will be appended to the opened modal
On submit the form will be POSTed via AJAX request to form's URL
Unsuccessful POST request will return errors, which will be shown under form fields in modal
Successful POST request will redirects to selected success URL

Python, Flask Method Not Allowed

I am currently learning python and am trying to write an app. I have the basics done. I followed a tutorial which was helpful but have gotten stuck. My understanding is 100% up to scratch yet so any help and reasoning behind it would be great.
I am getting a Method Not Allowed Error when trying to submit a form. I will post the code below and hopefully someone can help.

Your form is trying to POST data to the server. This is a HTTP POST request. You define GET and SET methods in your view. You need to use POST there.
#app.route('/new_action', methods=['GET', 'POST']) # Changed SET to POST here
#login_required
def new_action():
# ... what ever...
You should go through this RFC for HTTP. There is no SET-method.

#app.route('/new_action', methods=['GET', 'SET'])
This line of code is only allowing "GET" and "SET" methods, while you are trying to "POST" to that route.

Uploading/Deleting files from a database in Django

I'm trying to figure out a way to delete pictures I've uploaded to a carousel in django. Does anyone have a solution to this? I can't find any online examples that are clear to me. You can assume I have imported everything, and that all models, etc. are correct.
My code is below:
carousel.html:
{% load staticfiles %}
{% load filename %}
<div class="container">
<div class="row">
<div class="col-md-12">
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<div class="carousel-inner" role="listbox">
{% for document in documents %}
<div class="item {% if forloop.first %} active {% endif %}">
<div class="row">
<div class="col">
<li>{{document.docfile.name}}</li>
<img src = "{{STATIC_URL}}img/{{document|filename}}" >
<p align="center"><form style="text-align:center" action="{% url 'webportal:delete' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.Document.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.Document.errors }}
{{ form.Document }}
</p>
<p><input type="submit" value="Delete" /></p>
</form></p>
</div>
</div>
</div>
{% endfor %}
</div>
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>
<!-- /.carousel -->
</div>
</div>
<form action="{% url 'webportal:carousel' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
<p><input type="submit" value="Upload" /></p>
</form>
</div>
Views.py
def delete(request, my_id):
Deleted=get_object_or_404(Document, docfile=my_id)
if request.method=='POST':
form=DeleteForm(request.POST, instance=Deleted)
if form.is_valid():
Deleted.delete()
return HttpResponseRedirect('http://127.0.0.1:8000/alzheimers/')
else:
form=DeleteForm(instance=Deleted)
return render_to_response(
'webportal/index.html',
{'documents': documents, 'form': form,},
context_instance=RequestContext(request)
)
# Redirect to the document list after POST
def carousel(request):
# Handle file upload
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
newdoc = Document(docfile = request.FILES['docfile'])
newdoc.save()
# Redirect to the document list after POST
return HttpResponseRedirect('http://127.0.0.1:8000/alzheimers/')
else:
form = DocumentForm() # A empty, unbound form
# Load documents for the list page
documents = Document.objects.all()
#documents=DocumentForm().
# Render list page with the documents and the form
return render_to_response(
'webportal/index.html',
{'documents': documents, 'form': form,},
context_instance=RequestContext(request)
)

You don't wanna handle too much in one view. You could, but it makes ugly hard to maintain code. Better add a separate view for deleting. With this in your template loop.
<a href='{% url 'delete_document' pk=document.pk %}'>delete</a>
Then add a new url pattern with a pk argument:
url(r'^document/delete/(?P<pk>\d+)/$', "delete_document", name="delete_document"),
And a view like:
def delete_document(request, pk):
try:
Docuent.objects.get(pk=pk).delete()
except Document.DoesNotExist:
pass
return HttpResponseRedirect(...)

WTForms when rendering two forms on the same page with a Recaptcha fields only one is displayed

I am using Flask with WTforms. I am also using the WTFRecaptcha plugin in order to use Captcha fields.
Turns out I need to use two forms on the same page. When I assign a captcha field on each form, one of the captchas is not rendered on the .html page. This is because the captcha is ALWAYS created with the same ID:
Captcha and forms declaration on my forms.py file:
from wtforms import PasswordField, StringField, validators, widgets, RadioField
from wtforms.form import Form
from wtfrecaptcha.fields import RecaptchaField
class FirstForm(Form):
"""First Form"""
#Omitting fields here
captcha_1 = RecaptchaField('Captcha', [], public_key='OMITTING_PUBLIC_KEY', private_key='OMITTING_PRIVATE_KEY', secure=True)
class Secondform(Form):
"""Second Form"""
#Omitting fields here
captcha_2 = RecaptchaField('Captcha', [], public_key='OMITTING_PUBLIC_KEY', private_key='OMITTING_PRIVATE_KEY', secure=True)
Route declaration:
#!/usr/bin/env python
from flask import Flask, render_template, request
from flask.ext.assets import Environment
from forms import FirstForm, SecondForm
from flask import request
from flask import jsonify
#app.route('/test')
def test_form():
"""Test."""
form_1 = FirstForm(request.form, captcha_1={'ip_address': request.remote_addr})
form_2 = SecondForm(request.form, captcha_2={'ip_address': request.remote_addr})
if request.method == 'POST' and (form_1.validate() or form_2.validate()) :
return "Instructions have been sent to your e-mail"

RESULT: Only one captcha is shown.
... Therefore if I have two captcha fields (Possible on two different forms), one won't display.
Any solutions/suggestions?

This is well a well documented limitation of Recaptcha
Currently, the Google captcha mechanism offer only one captcha form per page
I would encourage you to rethink the way you are organizing your page. Forms in HTML are simple by design. Most of the tooling built around them assumes that a page does one thing and submits the result to the server in a single form submission.
Disclaimer: I don't really know anything about your code. Proceeding regardless: it smells like your design might be a too clever. What I mean by this is that if you haven't seen it done somewhere else and google's tooling doesn't support it the issue is probably with your approach.
If you need to commit the result of a single stateless transaction then a <form> is appropriate and WTForms is a great tool to generate it. If you need something richer you might consider the following:
Break your forms out into multiple pages. A simple set of hyperlinks can provide an easily navigable hierarchy.
Build your DOM with javascript and submit to a RESTful endpoint(you can even use WTForms for validation by converting the request body into a MultiDict and Recaptcha supports AJAX)
Build your <form> dynamically with javascript and switch the action to correspond to the correct form processor on your server.

This is not possible with reCAPTCHA.
See the related ASP.NET question: Multiple reCAPTCHAs in one ASP.Net page
And for possible workarounds: How do I show multiple recaptchas on a single page?
