Hi Joe:
Thanks for the reply.
I did try using a custom class in admin.py
class LongTextinput(TextInput):
def __init__(self, *args, **kwargs):
attrs = kwargs.setdefault('attrs', {})
# code below aims to add a size="100" attribute
# to rendered html
attrs.setdefault('size', 100)
super(LongTextinput, self).__init__(*args, **kwargs)
implemented with formfields_ovverides as
in :
formfield_overrides = {
models.CharField: {'widget': LongTextinput},
}
but did not have the desired effect.
the larger question is:
why is formfield_overrides not having the effect I expected?
I.E. size="100" is added to the rendered html.
According to documentation the implementation should be pretty straightforward.
Do you suppose that there is a particular plugin that enables
formfield_overrides?
**OR** is {{ form.as_p }} in the template inhibiting the rendering?
My goal was not to change the max_length attribute, but the size attribute in
the rendered HTML code.
For the record, css widens the input field, and that gave me the
input width I sought, but the edification I seek is to understand
how to use formfield_overrides.
cheers
