Hi,
I am trying to do the same thing as the OP. Add a quantity input field to a
grid and then use Callback to work with the product_id and quantity. I just
don't seem to be able to pass the quantity to the callback function.
Using this method I don't get a value from quantity.
links=[
lambda row: INPUT(_type='number', _value=0,
_name='qty'),
lambda row: A(T('Add'),
callback=URL('_add_product',args=[row.id, request.vars.qty]),
_class='button btn btn-default')
]
)
If I use args or vars doesn't matter. The point is I always get 'None' for
the Quantity field.
I have tried wrapping the grid in a form and the input in a form. I am sure
I am doing something simple wrong.
Here's the whole function:
@auth.requires_login()
def product_add():
productid = request.args(0)
grid = SQLFORM.grid(db.product.id == productid,
args=[productid],
create=False,
editable=False,
deletable=False,
fields=[db.product.productname,
db.product.purchasecost,
db.product.monthlycost,
db.product.smallimage],
links=[
lambda row: FORM(INPUT(_type='number',
_value=0, _name='qty')),
lambda row: A(T('Add'),
callback=URL('_add_product',
vars=dict(productid=productid, qt=request.vars.qty)),
_class='button btn btn-default')
]
)
return locals()
