Lucity 7.40 Enhancements: Attached Documents

Lucity added the ability to view and attach documents using Lucity Web for version 7.40.  This is one of several enhancements made for this release.  A few of these enhancements will be covered here on this blog in the coming weeks:

Documents can be attached and viewed using a new button on Lucity Web.  They can be attached one at a time or several documents at a time.  Here is a brief video which demonstrates how documents are viewed and attached in Lucity Web:

Documents in Lucity Web are opened using the default program for document’s file type (as defined on the end user’s system).

Lucity Web GIS also provides access to document attachments. Users can attach one or more documents to a single record or can attach one or more documents to a selected group of records.  This demo shows some of the functionality available for documents in Lucity Web GIS:

Administrators can customize which types of documents may be attached or viewed.  There are two ways to do this, the white list or the black list.  A white list limits users to only a specified range of file extensions. The black list option allows administrators to list just the file extensions which are not permitted.  By default Lucity uses the black list and specifies the following file types: exe,com,dll,ocx,bat,reg,tmp,dat,scr,bak,acl,acm,cpl,ax.  File types in either of these settings should only include the file extension (after the .) and should be comma delimited.  Users will be prevented from opening or attaching any dis-allowed file type.

Lucity does not store these documents on the web server, or in the database, and they are not streamed from the web server to the client.  The browser on the client machine accesses these documents directly from your local network.  Lucity stores the path where the file resides.  The user account logged into the client machine running Internet Explorer is the account that will be used to access the file.  If that local Windows user does not have permissions to access a file, or if the file is not available on that user’s network, the file cannot be opened.

A system administrator must enable Lucity Web to access documents on the local file system and network for every client machine.  Several actions are required to enable this file access.  These actions can be managed with Group Policy.  For details, see the Lucity Administration manual in the “How To>>Web – Document Control Setup” section.
