Hi Gleb,

i think you want to generate report from background (python side) or from other model/resource.

you can do like this:

                # render report and get as pdf

                REPORT_ID = 'moduleName.template_id' # template id (that you have to find from report template)

                pdf = self.env.ref(REPORT_ID).render_qweb_pdf(record_id) # Give record id to generate for

                b64_pdf = base64.b64encode(pdf[0])

Now you will get pdf in b64_pdf so you can set this as attachment or send as email whatever you want

don't forget to accept answer if helpful.

thank you

f you mean that "/home" is a module directory,, then you just can call template by <t t-call="home.template_xml_id" />

Regards
