how to create a qweb report

0. moduel structure

module
| report
|    customize_report.py
| views
|    report_layout_view.xml
| report.xml
| __init__.py
| __openerp__.py
| ...

1. create a report

if no 2nd step, the value of file and name 2nd step.
if 2nd step, the value of should be the template id in 2nd step

<report
id="report_sale_order_libiya_xxx"
string="Sale Order Libiya"
model="sale.order"
report_type="qweb-pdf"
file="module.report_sale_order_xxx"
name="module.report_sale_order_xxx"
/>

2. create a report translation (optional)

<template id="report_sale_order_xxx">
<t t-call="report.html_container">
<t t-foreach="doc_ids" t-as="doc_id">
<t t-raw="translate_doc(doc_id, doc_model, 'partner_id.lang', 'module.report_sale_order_xxx_document')"/>
</t>
</t>
</template>

create report layout

odoo is using bootstrap for web layout

http://www.w3cschool.cc/bootstrap/bootstrap-grid-system.html

<template id="report_sale_order_xxx_document">
<t t-call="report.external_layout">
<div class="page">
<div class="oe_structure"/>
<table class="dest_address">
<tr>
<td>
<strong>Customer address:</strong>
<div t-field="o.partner_id"
t-field-options='{"widget": "contact", "fields": ["address", "name", "phone", "fax","email","vat"], "no_marker": false}'/>
<p t-if="o.partner_id.vat">VAT: <span t-field="o.partner_id.vat"/></p>
</td>
</tr>
</table>

<div class="row mt32 mb32" id="informations">
<div t-if="o.client_order_ref" class="col-xs-3">
<strong>Invoice:</strong>
<p t-field="o.client_order_ref"/>
</div>
<div t-if="o.user_id.name" class="col-xs-3">
<strong>Salesperson:</strong>
<p t-field="o.user_id.name"/>
</div>
<div t-if="o.payment_term" class="col-xs-3">
<strong>Payment Term:</strong>
<p t-field="o.payment_term"/>
</div>
</div>

</template>

create customize report rending function

There are two ways to registrating

method 1

odoo use this way to reuse the code of v7.

import time
from openerp.report import report_sxw
from openerp.osv import osv

class sale_report_xxx(report_sxw.rml_parse):
def _print_test(self):
return "good"

def __init__(self, cr, uid, name, context):
super(sale_report_libiya, self).__init__(cr, uid, name, context=context)
self.localcontext.update({
'time': time,
'cr':cr,
'uid': uid,
'curr_rec': self.curr_rec,
'compute_currency': self.compute_currency,
'print_test': self._print_test,
'print_test2': "good2",
'other_methods'self._other_methods,
})

class report_pos_details(osv.AbstractModel):
_name = 'report.sale_webkit_report_libiya.report_sale_order_xxx'
_inherit = 'report.abstract_report'
_template = 'module.report_sale_order_xxx'
_wrapped_report_class = sale_report_xxx

Method 2

code taken from odoo documentation

from openerp import api, models

class ParticularReport(models.AbstractModel):
_name = 'report.<<module.reportname>>'
@api.multi
def render_html(self, data=None):
report_obj = self.env['report']
report = report_obj._get_report_from_name('<<module.reportname>>')
docargs = {
'doc_ids': self._ids,
'doc_model': report.model,
'docs': self,
}
return report_obj.render('<<module.reportname>>', docargs)

tips

website editor

After this module installed, website manager can edit report online once report type is set in backend to html.

After the online edit, the report can be changed back to pdf to print pdf document later.
output image on Qweb report

除了以上问题外，还有一个经常遇到的问题就是在报表中输出image，这里也来介绍个方法：

Now I'm printing the image in the QWeb report this way:

<span t-field="product_id.image_small" t-field-options="{"widget": "image", "class": "img-rounded"}"/>

说是原创，实在无语，多多见凉。
