""" Domain expression processing
|
|
|
|
The main duty of this module is to compile a domain expression into a
|
|
SQL query. A lot of things should be documented here, but as a first
|
|
step in the right direction, some tests in test_expression.py
|
|
might give you some additional information.
|
|
|
|
For legacy reasons, a domain uses an inconsistent two-levels abstract
|
|
syntax (domains are regular Python data structures). At the first
|
|
level, a domain is an expression made of terms (sometimes called
|
|
leaves) and (domain) operators used in prefix notation. The available
|
|
operators at this level are '!', '&', and '|'. '!' is a unary 'not',
|
|
'&' is a binary 'and', and '|' is a binary 'or'. For instance, here
|
|
is a possible domain. (<term> stands for an arbitrary term, more on
|
|
this later.)::
|
|
|
|
['&', '!', <term1>, '|', <term2>, <term3>]
|
|
|
|
It is equivalent to this pseudo code using infix notation::
|
|
|
|
(not <term1>) and (<term2> or <term3>)
|
|
|
|
The second level of syntax deals with the term representation. A term
|
|
is a triple of the form (left, operator, right). That is, a term uses
|
|
an infix notation, and the available operators, and possible left and
|
|
right operands differ with those of the previous level. Here is a
|
|
possible term::
|
|
|
|
('company_id.name', '=', 'OpenERP')
|
|
|
|
The left and right operand don't have the same possible values. The
|
|
left operand is field name (related to the model for which the domain
|
|
applies). Actually, the field name can use the dot-notation to
|
|
traverse relationships. The right operand is a Python value whose
|
|
type should match the used operator and field type. In the above
|
|
example, a string is used because the name field of a company has type
|
|
string, and because we use the '=' operator. When appropriate, a 'in'
|
|
operator can be used, and thus the right operand should be a list.
|
|
|
|
Note: the non-uniform syntax could have been more uniform, but this
|
|
would hide an important limitation of the domain syntax. Say that the
|
|
term representation was ['=', 'company_id.name', 'OpenERP']. Used in a
|
|
complete domain, this would look like::
|
|
|
|
['!', ['=', 'company_id.name', 'OpenERP']]
|
|
|
|
and you would be tempted to believe something like this would be
|
|
possible::
|
|
|
|
['!', ['=', 'company_id.name', ['&', ..., ...]]]
|
|
|
|
That is, a domain could be a valid operand. But this is not the
|
|
case. A domain is really limited to a two-level nature, and can not
|
|
take a recursive form: a domain is not a valid second-level operand.
|
|
|
|
Unaccent - Accent-insensitive search
|
|
|
|
OpenERP will use the SQL function 'unaccent' when available for the
|
|
'ilike' and 'not ilike' operators, and enabled in the configuration.
|
|
Normally the 'unaccent' function is obtained from `the PostgreSQL
|
|
'unaccent' contrib module
|
|
<http://developer.postgresql.org/pgdocs/postgres/unaccent.html>`_.
|
|
|
|
.. todo: The following explanation should be moved in some external
|
|
installation guide
|
|
|
|
The steps to install the module might differ on specific PostgreSQL
|
|
versions. We give here some instruction for PostgreSQL 9.x on a
|
|
Ubuntu system.
|
|
|
|
Ubuntu doesn't come yet with PostgreSQL 9.x, so an alternative package
|
|
source is used. We use Martin Pitt's PPA available at
|
|
`ppa:pitti/postgresql
|
|
<https://launchpad.net/~pitti/+archive/postgresql>`_.
|
|
|
|
.. code-block:: sh
|
|
|
|
> sudo add-apt-repository ppa:pitti/postgresql
|
|
> sudo apt-get update
|
|
|
|
Once the package list is up-to-date, you have to install PostgreSQL
|
|
9.0 and its contrib modules.
|
|
|
|
.. code-block:: sh
|
|
|
|
> sudo apt-get install postgresql-9.0 postgresql-contrib-9.0
|
|
|
|
When you want to enable unaccent on some database:
|
|
|
|
.. code-block:: sh
|
|
|
|
> psql9 <database> -f /usr/share/postgresql/9.0/contrib/unaccent.sql
|
|
|
|
Here :program:`psql9` is an alias for the newly installed PostgreSQL
|
|
9.0 tool, together with the correct port if necessary (for instance if
|
|
PostgreSQL 8.4 is running on 5432). (Other aliases can be used for
|
|
createdb and dropdb.)
|
|
|
|
.. code-block:: sh
|
|
|
|
> alias psql9='/usr/lib/postgresql/9.0/bin/psql -p 5433'
|
|
|
|
You can check unaccent is working:
|
|
|
|
.. code-block:: sh
|
|
|
|
> psql9 <database> -c"select unaccent('hélène')"
|
|
|
|
Finally, to instruct OpenERP to really use the unaccent function, you have to
|
|
start the server specifying the ``--unaccent`` flag.

The principle is to pop elements from a leaf stack one at a time.
|
|
Each leaf is processed. The processing is a if/elif list of various

cases that appear in the leafs (many2one, function fields, ...).
|
|
|
|
Three things can happen as a processing result:
|
|
|
|
- the leaf is a logic operator, and updates the result stack
|
|
accordingly;
|
|
- the leaf has been modified and/or new leafs have to be introduced
|
|
in the expression; they are pushed into the leaf stack, to be
|
|
processed right after;
|
|
- the leaf is converted to SQL and added to the result stack
