I'm struggling to get my head round django forms.. I've been reading various documentation but just can't quite grasp the concepts. I have got to grips with models, views and templates. What I am trying to do is to create a form with various fields composing of dropdown lists and checkboxes which are populated by values in a database.

I have a working app called vms. Using the models.py I have a built a simple schema that holds size and type. Size consists of 'small', 'medium' & 'large'. Type is 'windows' & 'linux'. Using the admin site, I can add an extra size, for example 'Extra Large'.

What I would like to do is create a form that has a drop down list of the vm sizes. If an extra size gets added via the admin site, I would like that size to appear in the drop down list.

I would submit my attempts at the code, but actually am struggling with the concepts. Can anyone help guide me in how to accomplish the above?

Thanks Oli

Simply use CharField in your modelform as below:

SIZES_CHOICES = (
    ('size1', 'M'),
    ('size2', 'L'),
)
size = models.CharField(max_length=100, choices=SIZES_CHOICES, default=size1)

in the above code, size1 is the value which will be going to store in your database as name 'size1' and in the drop-down menu, there will be an option is 'M' of right side.you can mentioned any name to these options.
