@rafaelbn, please check

Maybe is not a problem of this module. Stages are not working, I cannot change stages in opportunities.

@pedrobaeza I tried to install it on my local. Installation failed with log below:

File "/home/andhit_r/odoo8/oca_crm/crm_lead_substage/report/crm_lead_report.py", line 24, in init
cr.execute("CREATE OR REPLACE VIEW crm_lead_report AS (%s)" % view_def)

res = self.obj.execute(query, params)
ProgrammingError: syntax error at or near "."
LINE 1: ... REPLACE VIEW crm_lead_report AS ( SELECT c.i c.substage...

I then raise your view_def variable. It showed:

SELECT c.i c.substage_id,
d, c.date_deadline, count(c.id) AS nbr_cases, c.date_open AS opening_date, c.date_closed, c.date_last_stage_update, c.user_id, c.probability, c.stage_id, c.type, c.company_id, c.priority, c.section_id, c.campaign_id, c.source_id, c.medium_id, c.partner_id, c.country_id, c.planned_revenue, c.planned_revenue * (c.probability / 100::double precision) AS probable_revenue, c.create_date, date_part('epoch'::text, c.date_closed - c.create_date) / (3600 * 24)::double precision AS delay_close, abs(date_part('epoch'::text, c.date_deadline::timestamp without time zone - c.date_closed) / (3600 * 24)::double precision) AS delay_expected, date_part('epoch'::text, c.date_open - c.create_date) / (3600 * 24)::double precision AS delay_open
FROM crm_lead c
WHERE c.active = true
GROUP BY c.id

I think You miss a comma (,) after c.id

Same error showed on travis

I think it's because another module in this repo also overwrites the lead report without respecting inheritance chain (it's not easy in this case though).

This module only depend crm. I tested on fresh DB with demo data. I installed only this module after DB creation. No other module in this repo installed.

Here it's the trick I use to insert the field: https://github.com/OCA/crm/pull/74/files#diff-9f5df14bda3a6d61aac3b7c881180811R16

Maybe this is not the same in your Odoo revision?

@pedrobaeza I'm using Odoo a688bcd and crm repo from your fork (8.0-crm_lead_substate) acbf9f5 .

I can not install crm_lead_substate due error i mentioned previously

@pedrobaeza are you going to insert substage_id or replace stage_id with substage_id on crm.lead.report?

I'm inserting it, but the lack of inheritable methods for select, from and where parts make me do it that way to also allow another inheritances into account.

I have used another part of the sentence that is going to be for sure (the SELECT part), so now it's working. Runbot red status is because a warning.

Thanks for your reviews.

Tested on runbot 👍

I worry about the functional rationale for this feature - could it be adding avoidable complexity?
I would like to see, in the README, an example use case where additional Stages are clearly not enough.

Like @dreispt I am not sure about the rationale here but it is not a real blocking point

We will rethink this now and come back here. I close for now.
