Method Details [hide private]

__call__(self)
(Call operator)

source code 
return the related object when a ToOne relation is called

_add(self, obj)

source code 
add a to one side of a relationship if a relationship already exists clear it
Overrides: RelationshipBase.RelationshipBase._add

_getCopy(self, container)

source code 
Create ToOne copy. If this is the one side of one to many we set our side of the relation to point towards the related object (maintain the relationship across the copy).
Overrides: OFS.CopySupport.CopySource._getCopy

_remoteRemove(self, obj=None)

source code 
clear the remote side of this relationship
Overrides: RelationshipBase.RelationshipBase._remoteRemove

_remove(self, obj=None)

source code 
remove the to one side of a relationship
Overrides: RelationshipBase.RelationshipBase._remove

checkRelation(self, repair=False)

source code 
Check to make sure that relationship bidirectionality is ok.
Overrides: RelationshipBase.RelationshipBase.checkRelation

exportXml(self, ofile, ignorerels=[])

source code  
return an xml representation of a ToOneRelationship
<toone id='cricket'>
    /Monitors/Cricket/crk0.srv.hcvlny.cv.net
</toone>

hasobject(self, obj)

source code 
does this relation point to the object passed
Overrides: RelationshipBase.RelationshipBase.hasobject

manage_afterAdd(self, item, container)

source code 
Don't do anything here because we have on containment
Overrides: ZItem.ZItem.manage_afterAdd

manage_afterClone(self, item)

source code 
Don't do anything here because we have on containment
Overrides: ZItem.ZItem.manage_afterClone

manage_beforeDelete(self, item, container)

source code  

There are 4 possible states during when beforeDelete is called.
They are defined by the attribute _operation and can be: 
    -1 = object being deleted remove relation
    0 = copy, 1 = move, 2 = rename
Any state less than 1 will provoke deletion of the remote end of the
relationship.
ToOne doesn't call beforeDelete on its related object because its 
not a container.
Overrides: ZItem.ZItem.manage_beforeDelete

manage_workspace(self, REQUEST)

source code 
ZMI function to return the workspace of the related object
Overrides: App.Management.Tabs.manage_workspace

Class Variable Details [hide private]

__ac_permissions__

Value:
(('View', ('getPrimaryLink', 'getRelatedId')))
