Paper Formats
|
||
|
|
-------------
|
||
|
|
|
||
|
|
There is a model called Paper Format allowing to define details specific to
|
||
|
|
the PDF output. These details include margins, header line, ... Everything
|
||
|
|
related to the printed pdf. Defining a paper format is not mandatory as there
|
||
|
|
is a default one set on the company. If you want a specific report to be
|
||
|
|
associated to a specific paper format , just link the ir.actions.report.xml to
|
||
|
|
it.

Custom report
|
||
|
|
-------------
|
||
|
|
|
||
|
|
A generic report use the default rendering context, containing the magic
|
||
|
|
variables as explained before. If you want a new rendering context containing
|
||
|
|
anything you want to process your data Odoo AbstractModel, a custom module is
|
||
|
|
needed. These reports are called "particular report".
|
||
|
|
|
||
|
|
For a particular report, you have to write an Odoo Model containing a
|
||
|
|
render_html method. Classically, this method returns a call to the original
|
||
|
|
**QWeb render** with a **custom rendering context**.
