Thank you, that seems like the sort of small thing I'd be missing, but it
*still* didn't work?
Recap:
def get_category_choices():
all_categories = DBSession.query(Category).all()
return [(str(c.id), c.name) for c in all_categories]
categories = get_category_choices()
class ProductForm(colander.Schema):
categories = colander.SchemaNode(
colander.Set(),
widget=deform.widget.SelectWidget(
values=categories,
multiple=True,
),
default='3',
validator=colander.Length(min=1),
)
My appstruct looks like:
'categories': [{'id': '3', 'name': 'Category 3'}]
The HTML generated does not contain selected attribute:
<select name="categories" id="deformField4" multiple="multiple">
<option value="1">Category 1</option>
<option value="2">Category 2</option>
<option value="3">Category 3</option>
</select>
Mariano mentions setting it at render time... I suppose, but the deform
demo here
<http://deformdemo.repoze.org/sequence_of_defaulted_selects_with_initial_item/>
clearly
demonstrates the ability to set defaults within the SchemaNode (which I was
doing wrong before; thanks @replaceafill).
