Reports are written in HTML/QWeb, like all regular views in Odoo. You can use the usual QWeb control flow tools. The PDF rendering itself is performed by wkhtmltopdf.
If you want to create a report on a certain model, you will need to define this Report and the Report template it will use. If you wish, you can also specify a specific Paper Format for this report. Finally, if you need access to more than your model, you can define a Custom Reports class that gives you access to more models and records in the template.
Report
Every report must be declared by a report action.
For simplicity, a shortcut <report>
element is available to define a
report, rather than have to set up the action and its surroundings manually. That <report>
can take the following attributes:
id
- the generated record's external id
name
(mandatory)- only useful as a mnemonic/description of the report when looking for one in a list of some sort
model
(mandatory)- the model your report will be about
report_type
(mandatory)- either
qweb-pdf
for PDF reports orqweb-html
for HTML report_name
- the name of your report (which will be the name of the PDF output)
groups
Many2many
field to the groups allowed to view/use the current reportattachment_use
- if set to True, the report will be stored as an attachment of the record
using the name generated by the
attachment
expression; you can use this if you need your report to be generated only once (for legal reasons, for example) attachment
- python expression that defines the name of the report; the record is
acessible as the variable
object
paperformat
- external id of the paperformat you wish to use (defaults to the company's paperformat if not specified)
Example:
<report
id="account_invoices"
model="account.invoice"
string="Invoices"
report_type="qweb-pdf"
name="account.report_invoice"
file="account.report_invoice"
attachment_use="True"
attachment="(object.state in ('open','paid')) and
('INV'+(object.number or '').replace('/','')+'.pdf')"
/>
Report template
Minimal viable template
A minimal template would look like:
<template id="report_invoice">
<t t-call="report.html_container">
<t t-foreach="docs" t-as="o">
<t t-call="report.external_layout">
<div class="page">
<h2>Report title</h2>
<p>This object's name is <span t-field="o.name"/></p>
</div>
</t>
</t>
</t>
</template>
Calling external_layout
will add the default header and footer on your
report. The PDF body will be the content inside the <div
class="page">
. The template's id
must be the name specified in the
report declaration; for example account.report_invoice
for the above
report. Since this is a QWeb template, you can access all the fields of the
docs
objects received by the template.
There are some specific variables accessible in reports, mainly:
docs
- records for the current report
doc_ids
- list of ids for the
docs
records doc_model
- model for the
docs
records time
- a reference to
time
from the Python standard library user
res.user
record for the user printing the reportres_company
- record for the current
user
's company
If you wish to access other records/models in the template, you will need a custom report.
Translatable Templates
If you wish to translate reports (to the language of a partner, for example), you need to define two templates:
- The main report template
- The translatable document
You can then call the translatable document from your main template with the attribute
t-lang
set to a language code (for example fr
or en_US
) or to a record field.
You will also need to re-browse the related records with the proper context if you use
fields that are translatable (like country names, sales conditions, etc.)
Warning
If your report template does not use translatable record fields, re-browsing the record in another language is not necessary and will impact performances.
For example, let's look at the Sale Order report from the Sale module:
<!-- Main template -->
<template id="report_saleorder">
<t t-call="report.html_container">
<t t-foreach="docs" t-as="doc">
<t t-call="sale.report_saleorder_document" t-lang="doc.partner_id.lang"/>
</t>
</t>
</template>
<!-- Translatable template -->
<template id="report_saleorder_document">
<!-- Re-browse of the record with the partner lang -->
<t t-set="doc" t-value="doc.with_context({'lang':doc.partner_id.lang})" />
<t t-call="report.external_layout">
<div class="page">
<div class="oe_structure"/>
<div class="row">
<div class="col-xs-6">
<strong t-if="doc.partner_shipping_id == doc.partner_invoice_id">Invoice and shipping address:</strong>
<strong t-if="doc.partner_shipping_id != doc.partner_invoice_id">Invoice address:</strong>
<div t-field="doc.partner_invoice_id" t-options="{"no_marker": True}"/>
<...>
<div class="oe_structure"/>
</div>
</t>
</template>
The main template calls the translatable template with doc.partner_id.lang
as a
t-lang
parameter, so it will be rendered in the language of the partner. This way,
each Sale Order will be printed in the language of the corresponding customer. If you wish
to translate only the body of the document, but keep the header and footer in a default
language, you could call the report's external layout this way:
<t t-call="report.external_layout" t-lang="en_US">
Tip
Please take note that this works only when calling external templates, you will not be
able to translate part of a document by setting a t-lang
attribute on an xml node other
than t-call
. If you wish to translate part of a template, you can create an external
template with this partial template and call it from the main one with the t-lang
attribute.
Barcodes
Barcodes are images returned by a controller and can easily be embedded in reports thanks to the QWeb syntax:
<img t-att-src="'/report/barcode/QR/%s' % 'My text in qr code'"/>
More parameters can be passed as a query string
<img t-att-src="'/report/barcode/?
type=%s&value=%s&width=%s&height=%s'%('QR', 'text', 200, 200)"/>
Useful Remarks
- Twitter Bootstrap and FontAwesome classes can be used in your report template
- Local CSS can be put directly in the template
Global CSS can be inserted in the main report layout by inheriting its template and inserting your CSS:
<template id="report_saleorder_style" inherit_id="report.style"> <xpath expr="."> <t> .example-css-class { background-color: red; } </t> </xpath> </template>
- If it appears that your PDF report is missing the styles, please check these instructions.
Paper Format
Paper formats are records of report.paperformat
and can contain the
following attributes:
name
(mandatory)- only useful as a mnemonic/description of the report when looking for one in a list of some sort
description
- a small description of your format
format
- either a predefined format (A0 to A9, B0 to B10, Legal, Letter,
Tabloid,...) or
custom
; A4 by default. You cannot use a non-custom format if you define the page dimensions. dpi
- output DPI; 90 by default
margin_top
,margin_bottom
,margin_left
,margin_right
- margin sizes in mm
page_height
,page_width
- page dimensions in mm
orientation
- Landscape or Portrait
header_line
- boolean to display a header line
header_spacing
- header spacing in mm
Example:
<record id="paperformat_frenchcheck" model="report.paperformat">
<field name="name">French Bank Check</field>
<field name="default" eval="True"/>
<field name="format">custom</field>
<field name="page_height">80</field>
<field name="page_width">175</field>
<field name="orientation">Portrait</field>
<field name="margin_top">3</field>
<field name="margin_bottom">3</field>
<field name="margin_left">3</field>
<field name="margin_right">3</field>
<field name="header_line" eval="False"/>
<field name="header_spacing">3</field>
<field name="dpi">80</field>
</record>
Custom Reports
The report model has a default get_html
function that looks for a model
named report.module.report_name
. If it exists, it will use it to
call the QWeb engine; otherwise a generic function will be used. If you wish
to customize your reports by including more things in the template (like
records of others models, for example), you can define this model, overwrite
the function render_html
and pass objects in the docargs
dictionary:
from odoo import api, models
class ParticularReport(models.AbstractModel):
_name = 'report.module.report_name'
@api.model
def render_html(self, docids, data=None):
report_obj = self.env['report']
report = report_obj._get_report_from_name('module.report_name')
docargs = {
'doc_ids': docids,
'doc_model': report.model,
'docs': self,
}
return report_obj.render('module.report_name', docargs)
Reports are web pages
Reports are dynamically generated by the report module and can be accessed directly via URL:
For example, you can access a Sale Order report in html mode by going to http://<server-address>/report/html/sale.report_saleorder/38
Or you can access the pdf version at http://<server-address>/report/pdf/sale.report_saleorder/38
