"""WebSubmit function - Displays a generic interface to upload, delete
and revise files.
To be used on par with Move_Uploaded_Files_to_Storage function:
- Create_Upload_Files_Interface records the actions performed by user.
- Move_Uploaded_Files_to_Storage execute the recorded actions.
NOTE:
=====
- Due to the way WebSubmit works, this function can only work when
positionned at step 1 in WebSubmit admin, and
Move_Uploaded_Files_to_Storage is at step 2
FIXME:
======
- One issue: if we allow deletion or renaming, we might lose track of
a bibdoc: someone adds X, renames X->Y, and adds again another file
with name X: when executing actions, we will add the second X, and
rename it to Y
-> need to go back in previous action when renaming... or check
that name has never been used..

"""
List files for revisions.
You should use Move_Uploaded_Files_to_Storage.py function in your
submission to apply the changes performed by users with this
interface.
@param parameters:(dictionary) - must contain:
+ maxsize: the max size allowed for uploaded files
+ minsize: the max size allowed for uploaded files
+ doctypes: the list of doctypes (like 'Main' or 'Additional')
and their description that users can choose from
when adding new files.
- When no value is provided, users cannot add new
file (they can only revise/delete/add format)
- When a single value is given, it is used as
default doctype for all new documents
Eg:
main=Main document|additional=Figure, schema. etc
('=' separates doctype and description
'|' separates each doctype/description group)
+ restrictions: the list of restrictions (like 'Restricted' or
'No Restriction') and their description that
users can choose from when adding/revising
files. Restrictions can then be configured at
the level of WebAccess.
- When no value is provided, no restriction is
applied
- When a single value is given, it is used as
default resctriction for all documents.
- The first value of the list is used as default
restriction if the user if not given the
choice of the restriction. CHOOSE THE ORDER!
Eg:
=No restriction|restr=Restricted
('=' separates restriction and description
'|' separates each restriction/description group)
+ canDeleteDoctypes: the list of doctypes that users are
allowed to delete.
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canReviseDoctypes: the list of doctypes that users are
allowed to revise
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canDescribeDoctypes: the list of doctypes that users are
allowed to describe
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canCommentDoctypes: the list of doctypes that users are
allowed to comment
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canKeepDoctypes: the list of doctypes for which users can
choose to keep previous versions visible when
revising a file (i.e. 'Keep previous version'
checkbox). See also parameter 'keepDefault'.
Note that this parameter is ~ignored when
revising the attributes of a file (comment,
description) without uploading a new
file. See also parameter
Move_Uploaded_Files_to_Storage.forceFileRevision
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canAddFormatDoctypes: the list of doctypes for which users can
add new formats. If there is no value,
then no 'add format' link nor warning
about losing old formats are displayed.
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canRestrictDoctypes: the list of doctypes for which users can
choose the access restrictions when adding or
revising a file. If no value is given:
- no restriction is applied if none is defined
in the 'restrictions' parameter.
- else the *first* value of the 'restrictions'
parameter is used as default restriction.
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canRenameDoctypes: the list of doctypes that users are allowed
to rename (when revising)
Eg:
Main|Additional
('|' separated values)
Use '*' for all doctypes
+ canNameNewFiles: if user can choose the name of the files they
upload (1) or not (0)
+ defaultFilenameDoctypes: Rename uploaded files to admin-chosen
values. List here the the files in
current submission directory that
contain the names to use for each doctype.
Eg:
Main=RN|Additional=additional_filename
('=' separates doctype and file in curdir
'|' separates each doctype/file group).
If the same doctype is submitted
several times, a"-%i" suffix is added
to the name defined in the file.
The default filenames are overriden
by user-chosen names if you allow
'canNameNewFiles' or
'canRenameDoctypes'.
+ maxFilesDoctypes: the maximum number of files that users can
upload for each doctype.
Eg:
Main=1|Additional=2
('|' separated values)
Do not specify the doctype here to have an
unlimited number of files for a given
doctype.
+ createRelatedFormats: if uploaded files get converted to
whatever format we can (1) or not (0)
+ keepDefault: the default behaviour for keeping or not previous
version of files when users cannot choose (no
value in canKeepDoctypes): keep (1) or not (0)
Note that this parameter is ignored when revising
the attributes of a file (comment, description)
without uploading a new file. See also parameter
Move_Uploaded_Files_to_Storage.forceFileRevision
+ showLinks: if we display links to files (1) when possible or
not (0)
+ fileLabel: the label for the file field
+ filenameLabel: the label for the file name field
+ descriptionLabel: the label for the description field
+ commentLabel: the label for the comments field
+ restrictionLabel: the label in front of the restrictions list
+ startDoc: the name of a file in curdir that contains some
text/markup to be printed *before* the file revision
box
+ endDoc: the name of a file in curdir that contains some
text/markup to be printed *after* the file revision
box
