Hi,
I want to use the reverse_related_objects fetch function.
I'm using eZ publish 4.0.1.
The doc says:
fetch( 'content', 'reverse_related_objects',
hash( 'object_id', object_id,
[ 'attribute_identifier', attribute_identifier, ]
[ 'all_relations', boolean, ]
[ 'group_by_attribute', boolean, ]
[ 'sort_by', sort_by ]
[ 'ignore_visibility', ignore_visibility ] ) )
I have 2 classes: Author (A) and Book (B).
The B as an attribute called 'author' where the datatype is 'Object relations'. When i want to see an author (A), i want to display all his books.
{def $OR = fetch( 'content', 'reverse_related_objects',
hash( 'object_id', $node.contentobject_id)
) }
First of all, i don't understand why I have an empty arry if i don't put this line on the hash 'all_relations', true()
{def $OR = fetch( 'content', 'reverse_related_objects',
hash(
'object_id', $node.contentobject_id,
'all_relations', true()
)
) }
now, i have all the reverse related objects of the current object. I want to have only the books. When i do this:
{def $OR = fetch( 'content', 'reverse_related_objects',
hash(
'object_id', $node.contentobject_id,
'all_relations', true(),
'attribute_identifier', 'book/author'
)
) }
it doesn't work... Any ideas , Thanks

hi there,
indeed you have to use the parameter all_relations to fetch related objects that are made through an attribute of type obejct relation or object relations. Try to set your attribute identifier by its id as integer and not as string
{def $OR = fetch( 'content', 'reverse_related_objects',
hash(
'object_id', $node.contentobject_id,
'all_relations', true(),
'attribute_identifier', 134
)
) }
for example

Thanks jean-Yves,
I have already tried. It doesn't work...
for example, the attribute author (id: 268) of the class book
{def $OR = fetch( 'content', 'reverse_related_objects',
hash(
'object_id', $node.contentobject_id,
'all_relations', true(),
'attribute_identifier', 268
)
) }

Ok,
It may sound stupid but i have come across really curious things in ez...
the following code is one that works in one of my apps
{def $related=fetch( 'content', 'reverse_related_objects',
hash( 'object_id', $pays.contentobject_id ,
'attribute_identifier','user/managed_countries',
'all_relations',true()))}
The only difference is the all_relations at the end of the statement...Give it a try !
Does not cost a thing ...

Argh, I've tried this... and it doesn't work!
{def $livres = fetch( 'content', 'reverse_related_objects',
hash( 'object_id', $node.contentobject_id,
'attribute_identifier', 570,
'all_relations', true()
)
)
}
Are you using eZ 4.0.1 ???

Well,
sorry not to be of any help,
My apps started in ez 4.0.1 an has been migrated in 4.0.2...
And it works... If it does not on your app, and if there are no errors in the error.log, i really don't know what to say... Please tell me when you find out what was wrong ...

Hi Seb,
Have you tried using only hard-coded values ? Without the "all_relations" parameter, useless when you specify the attribute ? {def $OR = fetch( 'content', 'reverse_related_objects',
hash(
'object_id', 1234,
'attribute_identifier', 268
)
) }
Ca, c'est fait !
