Attachments can be added via an attachment widget in the agent interface. For this, you need to use the <attachment> SimpleTag within a certain widget instance.

<attachment> </attachment>

Parsing

Anchor
parsing parsing

Parsing attachment content is possible only if the attachment file size does not exceed 30 MBAttachment content parsing and indexing are possible only if the attachment file size is under 30 Mb. The limit is fixed and cannot be modified. If the file is bigger than 30 MbMB, it will not be indexed. The warning message related to the indexation will be written to logs. You will be able to find more information later in the Main Log (sys_log) table using the criteria below for the filter:

• • Level IS Warning

  • Message Contains {Attachment ID}

Indexing is performed only for specific file formats. The Content field will be automatically filled with the text content of the attached file if the file extension is included in the list: 'txt', 'ini', 'reg', 'csv', 'json', 'htm', 'html', 'doc' , 'docx', 'xls', 'xlsx'. Full Text Search is enabled within the Content field. It allows you to search globally for its content.

following event is implemented:

1. In the Attachments (sys_attachment) table record, the attachment content parsed from the provided file is placed. The attachment content is populated in the Content field, and the content encoding – in the Encoding field. The content encoding is automatically detected.

Attachment

Attachment records can be public or non-public. The publicity of attachments affects whether an attachment link will have an expiration date.

• Links to public attachments do not expire.
• Non-public attachments have a lifetime of 1 hour by default from the moment they are generated. The lifetime of a link is determined through the system property s3.presigned.link.lifetime.

The Is Public attribute on the Attachment form defines the publicity of attachments. 

To generate attachment links, log in and use the relative link `/attachments/${sys_attachment.sys_id}` to download attachments. 

Depending on the publicity of an attachment, two links can be generated. For example:

The table below describes the effect of the operation restrictions on an image field:

Restrict access to attachments

• Attachments can only be uploaded by a user with rights to create records in the Attachments (sys_attachment) table, and with rights to edit records to which they are trying to upload an attachment. To prevent a user from uploading an attachment, set up access control to one of these operations.
• Attachments can be deleted by a user with rights to delete records from the Attachments (sys_attachment) table, and with rights to edit or delete the record from which they are trying to delete an attachment.
• Attachments can be downloaded by a user with rights to read the Attachments (sys_attachment) table and the record to which the attachment is attached.
• Copying can be done by a user with read access to the table of the record to which the original attachment is attached, and with edit access to the table in which the copy is being made.

You can supplement the existing access control rules for the Attachments (sys_attachment) table with new rules containing other conditions. New rules should not contradict the existing ones. To do this, complete the steps below:

1. Navigate to System Security → Access Control (ACL).

2. Click New and fill in the fields.
