Hi have this structure:
db.py:
#DEFINE PRODUCT INPUT
db.define_table('product_input',
Field('product', db.product, notnull=True),
Field('total_price','decimal(7,2)', readable=False,writable=False),
Field('amount', 'integer', readable=False,writable=False),
Field('supplier', db.supplier, notnull=True),
Field('location', db.location, notnull=True),
Field('input_type', 'string'),
auth.signature,
format = lambda r: '%s %s %s %s [%s]' % (r.product.model.model,
r.product.manufacturer.manufacturer, r.product.part_number,
r.product.serial_number, r.product.expiration_date)
)
db.define_table('product_output',
Field('product', 'list:reference product_input', multiple=True),
Field('ship', db.ship, notnull=True),
Field('total_price', 'decimal(7,2)', writable=False),
Field('data_output', 'date', notnull=True),
Field('output_type', 'string', notnull=True),
auth.signature,
format = '%(product)s'
)
default.py:
def new_product_input():
form = SQLFORM(db.product_input)
if form.process().accepted:
session.flash = 'Registration Saved Successfully'
redirect(URL('product_input'))
elif form.errors:
response.flash = 'Attention: errors in the form.'
return dict(form=form)
view:
{{extend 'new-layout.html'}}
{{=form.custom.begin}}
<div class="content mt-3">
<div class="animated fadeIn">
<div class="col-lg-12">
<div class="card">
<div class="card-header">
<strong>Stock Output</strong> Add<div class="w2p_flash alert
alert-dismissable" style="color: red;">{{=response.flash or ''}}</div>
</div>
<div class="card-body card-block">
<div class="row form-group">
<div class="col col-md-3"><label for="text-input" class="
form-control-label">Product in Stock</label></div>
<div class="col-12
col-md-6">{{=form.custom.widget.product_input.product}}<small
class="form-text text-muted">Select the Product in Stock</small></div>
<div class="col col-md-2"><a class="btn btn-outline-primary"
href="{{=URL('product_input')}}" target="new" role="button">Add New Product
to Stock</a></div>
</div>
