*NO BW COMPAT*, benefit from cw 3.6 releasing of folder,file and blog
which use it to get update at the same time.
CMHN and PEGASE will need update (but won't go to 3.6 without update,
so seem fine).
"""This module regroups a set of structures that may be used to configure
various places of the generated web interface.
Primary view configuration
``````````````````````````
:primaryview_section:
where to display a relation in primary view. Value may be one of:
* 'attributes', display in the attributes section
* 'relations', display in the relations section (below attributes)
* 'sideboxes', display in the side boxes (beside attributes)
* 'hidden', don't display
:primaryview_display_ctrl:
how to display a relation in primary view. Values are dict with some of the
following keys:
:vid:
identifier of a view to use to display the result set. Defaults depends on
the section:
* 'attributes' section: 'reledit' view
* 'relations' section: 'autolimited' view
* 'sideboxes' section: 'sidebox' view
:label:
label for the relations section or side box
:limit:
boolean telling if the results should be limited according to the
configuration
:filter:
callback taking the related result set as argument and returning it
filtered
:order:
int used to control order within a section. When not specified,
automatically set according to order in which tags are added.
Notice those values are only considered if the relation is in a displayed
section (controlled by :attr:`primaryview_section`)
Index view configuration
````````````````````````
:indexview_etype_section:
entity type category in the index/manage page. May be one of
* 'application'
* 'system'
* 'schema'
* 'subobject' (not displayed by default)
Actions box configuration
`````````````````````````
:actionbox_appearsin_addmenu:
simple boolean relation tags used to control the "add entity" submenu.
Relations whose rtag is True will appears, other won't.
Automatic form configuration
````````````````````````````
:autoform_section:
where to display a relation in entity form, according to form type.
`tag_attribute`, `tag_subject_of` and `tag_object_of` methods for this
relation tags expect two arguments additionaly to the relation key: a
`formtype` and a `section`.
formtype may be one of:
* 'main', the main entity form
* 'inlined', the form for an entity inlined into another's one
* 'muledit', the multiple entity (table) form
section may be one of:
* 'hidden', don't display
* 'attributes', display in the attributes section
* 'relations', display in the relations section, using the generic relation
selector combobox (available in main form only, and not for attribute
relation)
* 'inlined', display target entity of the relation in an inlined form
(available in main form only, and not for attribute relation)
* 'metadata', display in a special metadata form (NOT YET IMPLEMENTED,
subject to changes)
:autoform_field:
specify a custom field instance to use for a relation
:autoform_field_kwargs:
specify a dictionnary of arguments to give to the field constructor for a
relation. You usually want to use either `autoform_field` or
`autoform_field_kwargs`, not both. The later won't have any effect if the
former is specified for a relation.
:autoform_permissions_overrides:
provide a way to by-pass security checking for dark-corner case where it can't
be verified properly. XXX documents.
