""" Processor for accounting expressions.
|
|
|
|
Expressions of the form <field><mode>[accounts][optional move line domain]
|
|
are supported, where:
|
|
* field is bal, crd, deb
|
|
* mode is i (initial balance), e (ending balance),
|
|
p (moves over period)
|
|
* accounts is a list of accounts, possibly containing % wildcards
|
|
* an optional domain on move lines allowing filters on eg analytic
|
|
accounts or journal
|
|
|
|
Examples:
|
|
* bal[70]: variation of the balance of moves on account 70
|
|
over the period (it is the same as balp[70]);
|
|
* bali[70,60]: balance of accounts 70 and 60 at the start of period;
|
|
* bale[1%]: balance of accounts starting with 1 at end of period.
|
|
|
|
How to use:
|
|
* repeatedly invoke parse_expr() for each expression containing
|
|
accounting variables as described above; this lets the processor
|
|
group domains and modes and accounts;
|
|
* when all expressions have been parsed, invoke done_parsing()
|
|
to notify the processor that it can prepare to query (mainly
|
|
search all accounts - children, consolidation - that will need to
|
|
be queried;
|
|
* for each period, call do_queries(), then call replace_expr() for each
|
|
expression to replace accounting variables with their resulting value
|
|
for the given period.
|
|
|
|
How it works:
|
|
* by accumulating the expressions before hand, it ensures to do the
|
|
strict minimum number of queries to the database (for each period,
|
|
one query per domain and mode);
|
|
* it queries using the orm read_group which reduces to a query with
|
|
sum on debit and credit and group by on account_id (note: it seems
|
|
the orm then does one query per account to fetch the account
|
|
name...);
|
|
* additionally, one query per view/consolidation account is done to
|
|
discover the children accounts.
