-Forms handling
-==============
-
-Automatically generated forms management for handled entities
--------------------------------------------------------------
-
-XXX FILLME
-
-* forms ``edition`` and ``creation``
-
-The form generated by default does not fit your needs? You are not
-required to re-do all by hands! :)
-
-* rtags primary, secondary, generated, generic,
-  `Entity.relation_category(rtype, x='subject')`
-* inline_view (now a rtag?)
-* widget specification
-
-Editing controller behavior by default (id: `edit`)
----------------------------------------------------
-
-Editing control
-```````````````
-
-Re-requisites: the parameters related to entities to edit are
-specified as follows ::
-
-  <field name>:<entity eid>
-
-where entity eid could be a letter in case of an entity to create. We
-name those parameters as *qualified*.
-
-1. Retrieval of entities to edit by looking for the forms parameters
-   starting by `eid:` and also having a parameter `__type` associated
-   (also *qualified* by eid)
-
-2. For all the attributes and the relations of an entity to edit:
-
-   1. search for a parameter `edits-<relation name>` or `edito-<relation name>`
-      qualified in the case of a relation where the entity is object
-   2. if found, the value returned is considered as the initial value
-      for this relaiton and we then look for the new value(s)  in the parameter
-      <relation name> (qualified)
-   3. if the value returned is different from the initial value, an database update
-      request is done
-
-3. For each entity to edit:
-
-   1. if a qualified parameter `__linkto` is specified, its value has to be
-      a string (or a list of string) such as: ::
-
-        <relation type>:<eids>:<target>
-
-      where <target> is either `subject` or `object` and each eid could be
-      separated from the others by a `_`. Target specifies if the *edited entity*
-      is subject or object of the relation and each relation specified will
-      be inserted.
-
-    2. if a qualified parameter `__clone_eid` is specified for an entity, the
-       relations of the specified entity passed as value of this parameter are
-       copied on the edited entity.
-
-    3. if a qualified parameter `__delete` is specified, its value must be
-       a string or a list of string such as follows: ::
-
-          <ssubjects eids>:<relation type>:<objects eids>
-
-       where each eid subject or object can be seperated from the other
-       by `_`. Each relation specified will be deleted.
-
-    4. if a qualified parameter `__insert` is specified, its value should
-       follow the same pattern as `__delete`, but each relation specified is
-       inserted.
-
-4. If the parameters `__insert` and/or `__delete` are found not qualified,
-   they are interpreted as explained above (independantly from the number
-   of entities edited).
-
-5. If no entity is edited but the form contains the parameters `__linkto`
-   and `eid`, this one is interpreted by using the value specified for `eid`
-   to designate the entity on which to add the relations.
-
-
-.. note::
-
-   * If the parameter `__action_delete` is found, all the entities specified
-     as to be edited will be deleted.
-
-   * If the parameter`__action_cancel` is found, no action is completed.
-
-   * If the parameter `__action_apply` is found, the editing is applied
-     normally but the redirection is done on the form
-     (see :ref:`RedirectionControl`).
-
-   * The parameter `__method` is also supported as for the main template
-     (XXX not very consistent, maybe __method should be dealed in the view
-     controller).
-
-   * If no entity is found to be edited and if there is no parameter
-     `__action_delete`, `__action_cancel`, `__linkto`, `__delete` or
-     `__insert`, an error is raised.
-
-   * Using the parameter `__message` in the form will allow to use its value
-     as a message to provide the user once the editing is completed.
-
-
-.. _RedirectionControl:
-
-Redirection control
-```````````````````
-Once editing is completed, there is still an issue left: where should we go
-now? If nothing is specified, the controller will do his job but it does not
-mean we will be happy with the result. We can control that by using the
-following parameters:
-
-* `__redirectpath`: path of the URL (relative to the root URL of the site,
-  no form parameters
-
-* `__redirectparams`: forms parameters to add to the path
-
-* `__redirectrql`: redirection RQL request
-
-* `__redirectvid`: redirection view identifier
-
-* `__errorurl`: initial form URL, used for redirecting in case a validation
-  error is raised during editing. If this one is not specified, an error page
-  is displayed instead of going back to the form (which is, if necessary,
-  responsible for displaying the errors)
-
-* `__form_id`: initial view form identifier, used if `__action_apply` is
-  found
-
-In general we use either `__redirectpath` and `__redirectparams` or
-`__redirectrql` and `__redirectvid`.
