excerpts : Print using database excerpts¶
The lino_xl.lib.excerpts plugin adds the notions of database
excerpt.
What is a database excerpt?¶
As an end user you can see a history of the documents you asked Lino to print by selecting .
As a site manager you can see all the documents that any user asked Lino to print by selecting .
These “documents somebody asked Lino to print” have a name. We call them database excerpts.
- database excerpt¶
A database object that represents the fact that a given user has requested a given printable document at a given moment.
End users can see a history of their printouts in .
When the end user clicks on a print button, Lino actually creates a database excerpt, then builds the printable file and finally instructs the user’s browser to show this file.
Excerpt types¶
Lino also has a table of excerpt types where the system administrator can configure which types of database excerpts are available on a site. You can see this list via .
- excerpt type¶
A configuration database object that specifies that a print button should appear for a given model.
The detailed structure of this table is documented on the ExcerptType
model.
When a Lino process starts up, it automatically reads this table and installs a “Print” action on every model of a site for which there is an excerpt type.
