installation fails base_sale_multichannels

Ok .. I got it working. Downloaded the trunk. Now I copied the folder for this module into my server/bin/addons directory.
In the CSV file are no entries with product_manager or group_product_manager.
After trying to install it again, I get a different error:

...
  File "/opt/openerp/server/bin/addons/base/ir/ir_model.py", line 609, in get_object_reference
    data_id = self._get_id(cr, uid, module, xml_id)
  File "/opt/openerp/server/bin/tools/misc.py", line 823, in cached_result
    result2 = fn(self2, cr, *args[:self.skiparg-2], **kwargs2)
  File "/opt/openerp/server/bin/addons/base/ir/ir_model.py", line 602, in _get_id
    raise ValueError('No references to %s.%s' % (module, xml_id))
  ValueError: No references to base_external_referentials.external_report_form_view

What do I have to do now?
I can edit the code in my folder base_sale_multichannels/ and subfiles - but where should I do what?

Thanks for your help
Chris

Hello Chris,

This kind of error normally occurs in one of the following circumstances:

1. Either the xml reference mentioned is not found.
2. Either the module on which we depend is not in the system.

Can you please make sure whether your addons directory contains the module 'base_external_referentials' or not?

If not, you will need to get this module from the same repository where you took base_sale_multichannel from.

Hope this helps.

Thanks,

Thank you .. I think there is sth wrong with my installation?

/opt/openerp/server/bin/addons is where I got my addons.
I just downloaded the whole trunk to my home dir and copied it to opt:

sudo cp -R /home/automater/Software/Office/openerpextras/extra-6.0/product_m2mcategories/ .
sudo cp -R /home/automater/Software/Office/openerpextras/extra-6.0/base_external_referentials/ .
sudo cp -R /home/automater/Software/Office/openerpextras/extra-6.0/base_sale_multichannels/ .
ls -lah
all folders are available.

Just to be sure:
sudo /etc/init.d/openerp-server stop
sudo /etc/init.d/openerp-server start

Restarting the client:
~/Software/Office/openerp-client-6.0.3/bin$ ./openerp-client.py
(It's inside my home directory, but still works fine).

Then I click on: Administration - Modules - Modules
Type in: base_sale_multichannels
Double click, install, apply scheduled upgrades and I get the error:

That looks fine for me.
The folder / module is there, the XML exists and is readable by the appropriate user.

:(

Hello Chris,

Can you see the file base_external_referentials/report_view.xml ?
Line 6 contains the definition of the xml record.

Thanks.

Yes, this file exists.
I opened it and see the following:

                <record id="external_report_form_view" model="ir.ui.view">
                        <field name="name">external_report_form_view</field>
                        <field name="model">external.report</field>
                        <field name="type">form</field>
                        <field name="arch" type="xml">
                                <form string="External Referential Reports">
etc.

I commented it out and tryed to install it again, but I keep on getting the same error.
What I don't understand is, what I have to comment out here.
Since the error is coming from:

  File "/opt/openerp/server/bin/addons/base/ir/ir_model.py", line 602, in _get_id
    raise ValueError('No references to %s.%s' % (module, xml_id))
ValueError: No references to base_external_referentials.external_report_form_view
Which means for me, that the software expects a reference to external_report_form_view?

Chris,

The software expects the reference to external_report_form_view from base_external_referentials module.

Based on what you say, it should get reference for sure.

You dont need to comment any code.

What is the addons-path you have given?

Thanks.

Ok, I deleted my comments - still no change.

But your point was exactly right:

I pointed my addons-path to my home directory, where I downloaded the trunk:
/home/automater/Software/Office/openerpextras/extra-6.0/

If I delete this, I get the following error during installation:

But there in the file: base_sale_multichannels/report.py
I can see:

from osv import osv, fields
from tools.translate import _
class external_report(osv.osv):
    _inherit = 'external.report'

So the inherit command doesn't work - but I'm not sure whether this is a way to go here?

If I put my addons_path back, I'm back with the old error - so it doesn't work either way :(

  File "/opt/openerp/server/bin/addons/base/ir/ir_model.py", line 602, in _get_id
    raise ValueError('No references to %s.%s' % (module, xml_id))

This is a placeholder text, the % sign is a variable where the error is inserted. The error is thrown here because this method initiated the installation of the xml record and failed.

The error originates from the xml file you are trying to install.

Additionally, you shouldnt copy the modules to your server addons. You should create symbolic links to the addons path so you can update your sources from launchpad.

Chris,

Kyle Waid is right .

I hope the problem might have been solved now.

It's so messy.
Now I downloaded everything again to another directory copied simply everything into the addon directory and changed my config files.
It's pretty ugly now, but it works now.

And of course, people who are new to this software use the guide that fits best. The openlabs guide is good, structured and leads us all the way through the installation.
It doesn't say anything about the date, that it is outdated or provides comments.
Form the community and online, I couldn't find a decent hint or installation manual.
It's a pitty. The software is good but the documentation is as rare as the support in the forums - unfortunately.

Thanks Kyle Waid - http://www.gcotech.com, that solved my question.
