I want to generate my own excel report using Excel report engine in odoo 8. someone please send me a simple excel report sample or any helping URL. I'll be very thankful to you ....
Here is a simple piece of code. There is really a lot of examples on the internet with good explanations. I suggest you go through the code in detail to see how it works (by the way I have copied the code also from somewhere - I cannot remember where. Also have a look at the examples here:https://github.com/OCA/reporting-engine/tree/8.0 The version 8 branch also have a number of examples.
You can add columns by editing the "my_change" variable.
from openerp.osv import orm
from openerp.addons.report_xls.utils import rowcol_to_cell, _render
from openerp.tools.translate import _
class account_move_line(orm.Model):
_inherit = 'abc.salesforecast'
# override list in custom module to add/drop columns or change order
def _report_xls_fields(self, cr, uid, context=None):
return [
'contract', 'proposal', 'description',
#'amount_currency', 'currency_name',
]
# Change/Add Template entries
def _report_xls_template(self, cr, uid, context=None):
"""
Template updates, e.g.
my_change = {
'move':{
'header': [1, 20, 'text', _('My Move Title')],
'lines': [1, 0, 'text', _render("line.move_id.name or ''")],
'totals': [1, 0, 'text', None]},
}
return my_change
"""
return {}
The code for the parser is as follows.
