METHODS

LedgerSMB::DBObject::Payment->new()
Inherited from LedgerSMB::DBObject. Please see that documnetation for details.
$payment->get_open_accounts()
This function returns a list of open accounts depending on the $payment->{account_class} property. If this property is 1, it returns a list of vendor accounts, for 2, a list of customer accounts are returned.

The returned list of hashrefs is stored in the $payment->{accounts} property. Each hashref has the following keys: id (entity id), name, and entity_class.

An account is considered open if there are outstanding, unpaid invoices attached to it. Customer/vendor payment threshold is not considered for this calculation.

text_amount($value)
Returns the textual representation, as defined in localization rules, for the numeric value passed.
get_metadata()
Semi-private method for preparing the object for other tasks, such as displaying payment options.
search()
Seturns a series of payments matching the search criteria.

Search results are also stored at $payment->{search_results}.

get_open_accounts()
Returns a list of open accounts for the payment operation.

These are also stored on $payment->{accounts}

$payment->get_entity_credit_account()
Returns billing information for the current account, and saves it to an arrayref at $payment->{entity_accounts}/
$payment->get_all_accounts()
This function returns a list of open or closed accounts depending on the $payment->{account_class} property. If this property is 1, it returns a list of vendor accounts, for 2, a list of customer accounts are returned.

The returned list of hashrefs is stored in the $payment->{accounts} property. Each hashref has the following keys: id (entity id), name, and entity_class.

$payment->reverse()
This function reverses a payment. A payment is defined as one source ($payment->{source}) to one cash account ($payment->{cash_accno}) to one date ($payment->{date_paid}) to one vendor/customer ($payment->{credit_id}, $payment->{account_class}). This reverses the entries with that source.
$payment->get_open_invoices()
This function returns a list of open invoices depending on the $payment->{account_class}, $payment->{entity_id}, and $payment->{curr} properties. Account classes follow the conventions above. This list is hence specific to a customer or vendor and currency as well.

The returned list of hashrefs is stored in the $payment->{open_invoices} property. Each hashref has the following keys: id (entity id), name, and entity_class.

$payment->get_open_invoice()
This function is an especific case of get_open_invoices(), because get_open_invoice() can search for a specific invoice, which can be searched by the $payment->{invnumber} variable
$payment->get_all_contact_invoices()
This function returns a list of open accounts depending on the $payment->{account_class} property. If this property is 1, it returns a list of vendor accounts, for 2, a list of customer accounts are returned. Attached to each account is a list of open invoices. The data structure is somewhat complex.

Each item in the list has the following keys: contact_id, contact_name, \ account_number, total_due, and invoices.

The invoices entry is a reference to an array of hashrefs. Each of these hashrefs has the following keys: invoice_id, invnumber, invoice_date, amount, discount, and due.

These are filtered based on the (required) properties: $payment->{account_class}, $payment->{business_type}, $payment->{date_from}, $payment->{date_to}, and $payment->{ar_ap_accno}.

The $payment->{ar_ap_accno} property is used to filter out by AR or AP account.

The following can also be optionally passed: $payment->{batch_id}. If this is patched, vouchers in the current batch will be picked up as well.

The returned list of hashrefs is stored in the $payment->{contact} property. Each hashref has the following keys: id (entity id), name, and entity_class.

list_open_projects
This method gets the current date attribute, and provides a list of open projects. The list is attached to $self->{projects} and returned.
list_departments
This method gets the type of document as a parameter, and provides a list of departments of the required type. The list is attached to $self->{departments} and returned.
list_open_vc
This method gets the type of vc (vendor or customer) as a parameter, and provides a list of departments of the required type. The list is attached to $self->{departments} and returned.
get_open_currencies
This method gets a list of the open currencies inside the database, it requires that $self->{account_class} (must be 1 or 2) exist to work.

WARNING THIS IS NOT BEING USED BY THE SINGLE PAYMENT SYSTEM....

list_accounting
This method lists all accounts that match the role specified in account_class property and are available to store the payment or receipts.
list_overpayment_accounting
This method lists all accounts that match the role specified in account_class property and are available to store an overpayment / advanced payment / pre-payment.
get_sources
This method builds all the possible sources of money, in the future it will look inside the DB.
get_exchange_rate(currency, date)
This method gets the exchange rate for the specified currency and date
get_default_currency
This method gets the default currency
get_current_date
This method returns the system's current date
get_vc_info
This method returns the contact informatino for a customer or vendor according to $self->{account_class}
get_payment_detail_data
This method sets appropriate project, department, etc. fields.
post_bulk
This function posts the payments in bulk. Note that queue_payments is not a common setting and rather this provides a hook for an add-on.

This API was developed early in 1.3 and is likely to change for better encapsulation. Currenty it uses the following structure:

Within the main hashref:

contact_count
The number of payments. One per contact.
contact_$row
for (1 .. contact_count), contact_$_ is the entity credit account's id associated with the current contact. We will call this $contact_id below.

For each contact id, we have the following, suffixed with _$contact_id:

source
invoice_count
Number of invoices to loop through
invoice_${contact_id}_$row
for $row in (1 .. invoice_count), each this provides the transaction id of the invoice.

Each invoice has the following attributes, suffxed with ${invoice_id}

amount
paid
net

In the future the payment posting API will become more standardized and the conversion between flat and hierarchical representation will be moved to the workflow scripts.

check_job
To be moved into payment_queue addon.
post_payment
This method uses payment_post to store a payment (not a bulk payment) on the database.
gather_printable_info
This method retrieves all the payment related info needed to build a document and print it. IT IS NECESSARY TO ALREADY HAVE payment_id on $self
get_open_overpayment_entities
This method retrieves all the entities with the specified account_class which have unused overpayments
get_unused_overpayments
This is a simple wrapper around payment_get_unused_overpayments sql function.
get_available_overpayment_amount
Simple wrapper around payment_get_available_overpayment_amount sql function.
init
Initializes the num2text system
num2text
Translates numbers into words.
