基于MOAC的FORM开发(转)

原创 Linux操作系统 作者:asiaidea 时间:2012-02-07 11:39:39 0 删除 编辑

A.首先最重要的是要在pre-form中初始化多OU

BEGIN

    APP_STANDARD.EVENT(‘PRE-FORM’);

//必须在APP_STANDARD.EVENT()后执行

MO_GLOBAL.init ('INV');--参数可以使’S’—OU’M’-OU,或者已经注册过的应用简称

END;

B.初始化后获取OU的信息,在Pre-form中获取OU信息,或在块上When-Create-Record获取OU信息

Pre-form

DECLARE

l_default_org_id number;

l_default_ou_name varchar2(240);

l_ou_count number;

BEGIN

...

mo_utils.get_default_ou(l_default_org_id, l_default_ou_name, l_ou_count);

:PARAMETER.mo_default_org_id) := l_default_org_id;

:PARAMETER.mo_default_ou_name := l_default_ou_name;

:PARAMETER.mo_ou_count := l_ou_count;

...

END;

When-Create-Record

IF :parameter.mo_default_org_id is not null and :block.org_id is null THEN

:block.org_id := :parameter.mo_default_org_id);

:block.operating_unit := :parameter.mo_default_ou_name;

END IF;

C.在各个触发器实现多OU的支持的代码

When-Create-Record Trigger of Operating Unit Field Block

IF (:parameter.mo_default_org_id IS NOT NULL ) THEN

   -- Defaulting org_id from profile option

   :block.org_id := :parameter.mo_default_org_id;

   :block.operating_unit := :parameter.mo_default_ou_name;

   -- Set policy context

   mo_global.set_policy_context('S’,:block.org_id);

ELSE

  mo_global.set_policy_context('M', null);

END IF;

IF : is not null\

 IF : <> nvl(:,-99) THEN

   -- Get the cache for current org

 END IF;

ELSE

 -- Refresh the cache

...

END IF;

When-Validate-Item Trigger of Operating Unit field

IF (: IS NOT NULL ) THEN

 IF : <> nvl(:,-99) THEN

    mo_global.set_policy_context('S', :block.org_id);

    -- Get the cache for the current org

 END IF;

ELSE -- :block.org_id is null

 mo_global.set_policy_context('M', null);

 -- Refresh the cache

END IF;

When-New-Record-Instance Trigger of Operating Unit Field Block

IF (: IS NOT NULL ) THEN

 IF : <> nvl(:,-99) THEN

   mo_global.set_policy_context('S', :block.org_id);

   -- Get the cache for the current org

 END IF;

ELSE -- :block.org_id is null, so set the context to multiple

 mo_global.set_policy_context('M', null);

 -- Refresh the cache

END IF;

Pre-Insert Trigger of Operating Unit Field Block

Use this trigger if the form. allows the user to commit multiple records.

IF (: IS NOT NULL ) THEN

 IF : <> nvl(:,-99) THEN

   mo_global.set_policy_context('S', :block.org_id);

   -- Get the cache for the current org

 END IF;

ELSE -- :block.org_id is null, so set the context to multiple

 mo_global.set_policy_context('M', null);

 -- Refresh the cache

END IF;

Pre-Query Trigger of Operating Unit Field Block

BEGIN

 IF :parameter.mo_ou_count = 1 THEN

   mo_global.set_policy_context(‘S’,:parameter.mo_default_org_id);

 ELSE

   mo_global.set_policy_context('M', null);

 END IF;

 -- Other Code

END;

Pre-Record Trigger of Operating Unit Field Block

use this trigger if the form. forces the user to commit each record.

IF (:parameter.current_record is not null and

    :parameter.current_record != :system.trigger_record) THEN

  IF (:system.form_status in ('CHANGED','INSERT')) THEN

    mo_global.set_policy_context('S', :parameter.old_org_id);

    -- Get the cache for the current org

    -- raise error message to the user to commit;

    -- raise form_trigger_failure;

  ELSE

    -- No pending commits.

    -- Reset the current record variable.

    :parameter.current_record := '';

  END IF;

ELSE

  -- User has not navigated to another record.

  -- Do not reset the current record variable.

  null;

END IF;

Pre-Update Trigger

Use this trigger if the form. allows the user to commit multiple records commits that are in different operating units.

IF (: IS NOT NULL ) THEN

  IF : <> nvl(:,-99) THEN

    mo_global.set_policy_context('S', :block.org_id);

    -- Get the cache for the current org

  END IF;

END IF;
