I have gone down the route of using the following controller code
(I've left out a few checks for simplicity)
recipes=db(db.recipe.id==id).select()
recipe=recipes[0]
form=SQLFORM(db.recipe, recipe)
return dict(form=form)
... and in the view
<form name="{{=form.formname}}" method="post"
action="controller_name">
<input type="hidden" name="id" value="{{=form.record.id}}">
<label>Name:</label><input type="text" name="{{=form.formname}}_name"
size="50" maxlength="50" value="{{=form.record.name}}"/>
etc.
This seems to work well BUT I want to use the same view for insert and
update and when inserting there is no record! It would be great to be
able to call a function that creates an recipe record with id=0 and
all fields set to default values. It must be quite simple by
iterating through the columns of the table definition but I don't
really know enough yet to just code it. More importantly does the
function already exist? I don't want to rely on cloning an existing
instance.
