Django/Python: form data doesn't get stored in database

Django 1.8 / Python 3.4

I wanna add data from an html-form via a Django view named "add" to my database. However, for some reason this just doesn't happen and I can't figure out what's wrong. Presumably the mistake is in the view's code, but what exactly do I need to change?

models.py

from django.db import models
from model_utils import Choices

class Entry(models.Model):
    user = models.CharField(max_length=50)
    title = models.CharField(max_length=200)
    description = models.TextField()
    due_date = models.DateField('Date')
    due_time = models.TimeField('Time')
    STATUS = Choices('Open', 'Done')
    status = models.CharField(choices=STATUS, default=STATUS.Open, max_length=4)

def __unicode__(self):
    return u"%s %s %s %s %s" % (self.user, self.title, self.description, self.expiry, self.status)

def expiry(self):
    return u"%s %s" % (self.due_date, self.due_time)

The interesting part of my add.html

    <td><input type="text" name="title"></td>
    <td><input type="text" name="description"></td>
    <td><input type="text" name="due_date"></td>
    <td><input type="text" name="due_time"></td>
    <td>
        <select name="status" size="1" selected value="Open">
            <option>Open</option>
            <option>Done</option>
        </select>
    </td>

forms.py

from django import forms
from django.forms.widgets import TextInput

class EntryForm(forms.Form):
    title = forms.CharField(max_length=200)
    description = forms.widgets.TextInput()
    due_date = forms.DateField()
    due_time = forms.TimeField()
    status = forms.ChoiceField(choices=[(x, x) for x in range(1, 2)])

And the relevant view in my views.py

from django import forms
from django.shortcuts import render
from django.shortcuts import redirect
from website.list.forms import EntryForm

def add(request):
    if request.method == "POST":
        form = EntryForm(request.POST) 
        if form.is_valid():
            new_entry = form.save()
            new_entry.save()
            return redirect('website')
    else:
        form = EntryForm() 
    return render(request,'add.html', {'form': form})

Any help is appreciated!

[EDIT]

So, this is what my add.html looks like now:

<form action="." method="post">
{% csrf_token %}
{{ form }}
    <br><input type="submit" value="Send"/>
    <br><br><a href="{% url 'overview' %}">Cancel</a>
</form>

And the slightly edited views.py again:

from django import forms
from django.shortcuts import render
from django.shortcuts import redirect
from www.todolist.forms import EntryForm
from django.contrib.auth.models import User

def add(request):
    if request.method == "POST":
        form = EntryForm(request.POST) 
        if form.is_valid())
            form.save()
            return redirect('website')
    else:
        form = EntryForm() 
    return render(request,'add.html', {'form': form})

Figured it out ... This is what forms.py has to look like in order for the save() function to work in the view:

class EntryForm(forms.ModelForm):
CHOICES = (
    ('1', 'Open'),
    ('2', 'Done'),
)
title = forms.CharField(max_length=200)
description = forms.CharField(widget=forms.Textarea)
due_date = forms.DateField()
due_time = forms.TimeField()
status = forms.ChoiceField(choices=CHOICES)

class Meta:
    model = Entry
    fields = '__all__'

The important things to notice are "ModelForm" instead of just "Form" and the class Meta information.

I am guessing you are getting an error here; form = EntryForm(request.POST) but because you are manually writing out the form html instead of using the Django form to do it, you aren't seeing the error.

https://docs.djangoproject.com/en/1.8/topics/forms/#the-template is how you should use Django to render your html for your Django form; and this by default will display any errors the happened when trying to validate your data.
