I have this code which inherits the function that passes the data to be shown in the report. I wanted to add a new "docs"  like so:

================

class MyCustomReport(models.AbstractModel):

    _inherit = 'report.my_addon.custom_report'

    def _get_report_values(self, docids, data=None):

​# here i get the original data first

        res = super(MyCustomReport, self)._get_report_values(docids, data)

        docs = res['docs']

        # i add my additional data

        dict_docs = {

            'my_add_on': self._my_function_to_get_the_data()

         }

​# i update the result

        res.update({

            'additional_docs': dict_docs

        })

        return res

======== ========

This returns:

{'doc_ids': [3], 'doc_model': 'account.move', 'docs': account.move(3,), 'qr_code_urls': {}, 'additional_docs': {'my_add_on': None}}

I tried adding it to my qweb .xml custom report. See code below for what i am currently working on. This custom_report_inherit_first_customis my first custom which works well since i am using the "docs" data.  This  custom_report_inherit_addon_second_custom returns an error because i can't pull the "additional_docs" data.

# inherit report invoice document > then add my customization

< # template id="second_custom_report_inherit" inherit_id="my_adodn.first_custom_report_inherit">

#  I tried logging what i have fetched

​ ​< t t-esc="o"/> # this returns 'docs'

​< t t-esc="o_a"/> # this returns nothing and causes an error when i call the parameter i added, saying it does not exist

< # / template>

# i try to inherit the report_invoice to add my new parameter

< # / template id="report_invoice_inherit" inherit_id="account.report_invoice">

​# i inherit the xpath : < xpath expr="'web.html_container'" position="inside" >

and the do the for each like the account.report_invoice and then call the template

               t t-foreach="additional_docs" t-as="o_a"   

                    t t-call="my_addon.second_custom_report_inherit"

I'm not sure how to get the second data to show in the report. Please help
