common.database.backends.cache package

Submodules

common.database.backends.cache.Cache_Context module

common.database.backends.cache.Cache_DB module

common.database.backends.cache.Cache_Database module

common.database.backends.cache.Cache_Security module

Creates packages and context in Cache database to support Astro-WISE Contexts.

This module creates the tables for AWEUSERS and AWEPROJECTS. For Cache they control the values inserted into the awecontet_sys table, which is then used in the join in VIEWs of tables.

common.database.backends.cache.Cache_Select module

The beginnings of an implementation for Logical Expression objects

These objects should be used by the database to build queries

class common.database.backends.cache.Cache_Select.LinkRef(prop, attr)

Bases: object

like(other)
class common.database.backends.cache.Cache_Select.Select(lhs, operator, rhs)

Bases: object

add_clause(operator, other_clause, other_param)

add the other_clause (and param) to self

copy()

Return coyp of self

current_mydb_only()

Only show mydb data of the current project. So do not show the mydb data of other projects ! But do show all other visible data.

get_input_sizes()
get_rows()

Generate query and return all object_id’s The Environment can contain directives to adjust the query, if so a copy of self is made and used

get_sql(select=None, rownum=0)

Get the sql from the query, default SELECT arguments are the type and object_id, use select argument to extend the rownum argument adds a where limit on the number of rows returned

max(attribute)

Return the item in a query for which “attribute” is largest.

min(attribute)

Return the item in a query for which “attribute” is smallest.

not_all_mydb()

Only show mydb data of the current project. So do not show the mydb data of other projects ! But do show all other visible data.

order_by(attribute)

Order the result of a query by increasing value of “attribute”.

order_by_desc(attribute)

Order the result of a query by decreasing value of “attribute”.

privileges_only(privileges=0)

limit the query to the given privileges

project_favourite()

Prefer project owned data over data from other projects.

project_only(project=None)

Filter the objects specific to the given project (name/id) or the current project.

public_data_only(public=True)

Limit the query to public data (when True) or private data when public is False

public_project_only(public=True, ids=[])

Limit the query to public projects (when public is True) or private projects when public is False or to the given project ids

user_only(user=None)

Filter the objects to the given user (name/id) or current user

vo_only()

Limit query to VO objects, so privileges 5

world_only()

Limit query to world objects, so privileges 4
