ODOO 11 report, object has no attribute 'report_action' - python-3.x

Question

Good day to all.
Trying to make custom ODOO 11 report to save it to pdf.
Report template(w/out any values, just for test purposes)
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<data>
<template id="contract_template">
<t t-call="web.html_container">
<div class="article">
<h2>Report title</h2>
<p>Report 01</p>
</div>
</t>
</template>
</data>
</odoo>
If I call this template from XML like this:
<report
id="custom_template_1"
model="res.partner.contract.wizard"
string="Contract"
report_type="qweb-pdf"
name="client_contracts.contract_template"
file="client_contracts.contract_template"
menu="False"
/>
And add button to view it works fine - it generate report.
But when I'm trying to generate this report with python code:
def get_pdf_contract(self):
context = self._generate_context()
return self.env.ref('client_contracts.contract_template').report_action(self, data=context)
And add button to view:
<button string="Test pdf x" type="object" name="get_pdf_contract" />
When I press this button there is an error:
AttributeError: 'ir.ui.view' object has no attribute 'report_action'
Anyone can give me helping hand with that? Thanx for any help.

Answer 1

Found solution.
For anyone, who get same error/trouble - solution.
Just skip the
return self.env.ref('client_contracts.contract_template').report_action(self, data=context)
part, and replace it with
return {'type': 'ir.actions.report','report_name': 'client_contracts.contract_template','report_type':"qweb-pdf",'data': context,}
where context - previously generated dict of values, that need to be passed to template.
client_contract - name of module, conrtact_template - name of template

Answer 2

replace
return self.env.ref('client_contracts.contract_template').report_action(self, data=context)
with
return self.env.ref('client_contracts.custom_template_1').report_action(self, data=context)
means
return self.env.ref('module.report id').report_action(self,data=context)

The solution to this stack overflow question link, works fine.
To note: the report_id referenced below should refer to the report where you have declared name of report and type and file ... and not the template_id.
return self.env.ref('module_name.report_id').report_action(self, data=context)
