Loading data using CSV files

While you can do everything you need with XML files, this format is not the most convenient when you need to provide larger amounts of data, especially given that many people are more comfortable preprocessing data in Calc, or some other spreadsheet software. Another advantage of this format is that it is what you get when you use the standard export function. In this recipe, we'll have a look at importing table-like data.

How to do it...

Traditionally, access control lists (ACLs), (refer to Chapter 10, Access Security) are a type of data that is loaded via CSV files:

1. Add security/ir.model.access.csv to your data files:

   'data': [
       …
       'security/ir.model.access.csv',
   ],

2. Add an ACL for our books in this file:

   "id","name","model_id:id","group_id:id","perm_read",
       "perm_write","perm_create","perm_unlink"
   "access_library_book_user","ACL for books",
       "model_library_book","base.group_user",1,0,0,0

Now we have an ACL that permits normal users to read book records...
