549	StaticField formfield	pspierce@…	Adrian Holovaty	"Hugo recommended something similar but on a ""per form"" level.  However, I would like to see a StaticField form field.  The field would simply return the data when rendered.  Here is a use case.  

I work for Bertelsmann and run a program that creates replacements for Books On Tape and Random House audio for their product line that is sold to libraries.  Audio books have several components. The schema has a parent table called ""product"" with a child table ""component.""  The components are designated, component #1, component #2....  componentnum is set to editable=false in the model.  This causes a problem when using manipulators in that the editable field does not come through as it is not editable and is therefore not in the 'form' context variable.  I need this field to properly label the rows when editing and need them in the proper context of the form as they are labels.  I have added a StaticField in formfields.py for my own use and it works fine subclassing the manipulators to add it.  What I am requesting is:

#1 a StaticField

{{{
class StaticField(FormField):
    def __init__(self, field_name):
        self.field_name = field_name

    def render(self, data):
        if data is None:
            data = ''
        if isinstance(data, unicode):
            data = data.encode('utf-8')
        return data

    def html2python(data):
        return data

    html2python = staticmethod(html2python)
}}}


#2 Have manipulators return editable=false fields as StaticFields.  I haven't implemented this yet but am planning on doing it soon and currently have just changed those editable=false fields that I need to editable but change their field to StaticFields.

If this ticket is rejected, I will implement it for myself; however, if there is a way to implement this and I have overlooked it, I would be appreciative for some direction on how to do it."	enhancement	closed	Core (Other)		normal	wontfix			Unreviewed	0	0	0	0	0	0
