Hi,
Let me give you a code sample that would be hopefully a push in the right
direction.
Simply follow these steps:
1. Create your model. Its the code interface to your data source
(database)
2. Create your form. Forms are used for processing input data
(validation, error reporting etc)
3. Create your view. You should at least be able to link up a url
pattern to a view. If you can't please go through the tutorial
4. Create your template. This is the html returned to the client.
Note: Samples for your consideration:
#--- in models.py
from django.db import models
from django import forms
CHOICES = (('big', 'big'),('medium', 'medium'), ('small', 'small'))
class SimpleColumn(models.Model):
my_column = models.CharField(max_length=255, choices=CHOICES)
class SimpleColumnForm(forms.ModelForm):
class Meta:
model = SimpleColumn
#-- in views.py
from django.shortcuts import render
from models import SimpleColumnForm
def view_column(request):
if request.method == "POST":
form = SimpleColumnForm(request.POST)
if form.is_valid():
form.save()
else:
form = SimpleColumnForm()
return render(request, 'view_column.html', {'form': form})
<!-- In template view_column.html -->
<form method="POST">
{% csrf_token %}
{{ form }}
<button>Save</button>
</form>
Please go through the tutorial!
https://docs.djangoproject.com/en/1.4//intro/tutorial01/
It is very well written and after 1 hour or so you will have gotten the
concepts.
Enjoy Django!
