Question

I get the error “No references to product.group_product_manager” when I try to install the module product_images_olbs.

I have an OpenERP V 6.0.2 instance running on Ubuntu 10.04. But it seems I run into a documented error. This error shows up in the client (running on windows) when I want to install some modules:

I was trying to install the product_images_olbs module 6.0.0.1

After some research I found 2 bugreports that seem to fit:

https://bugs.launchpad.net/magentoerpconnect/+bug/695516

https://bugs.launchpad.net/openobject-addons/+bug/695084

Edit: The solution in this case was actually that I have to use the latest version of product_images_olbs.

I thought I was using it but this was not the case, and this was caused by my wrong usage of bazaar. (I come from git but getting used to bazaar more and more 😉

And the accepted answer is correct if applied to the old version of the module.

This is the new version of \addons\product_images_olbs\security\ir.model.access.csv (from revision 5486):

"id","name","model_id:id","group_id:id","perm_read","perm_write","perm_create","perm_unlink"
"access_product_images_olbs_product_images","product_images_olbs_product_images","model_product_images","base.group_sale_manager",1,1,1,1 

An old version of the same file:

"id","name","model_id:id","group_id:id","perm_read","perm_write","perm_create","perm_unlink"
"access_product_images_olbs_product_images","product_images_olbs_product_images","model_product_images","product.group_product_manager",1,1,1,1 

The old file has references to product.group_product_manager, which is no longer correct for OpenERP 6.0.2

Answer 1

My memory’s a bit hazy, but I think that error means that one of the XML files in the module you are trying to install has a reference to a record in the product module with id group_product_manager, but the product module doesn’t contain any record with that id.

Do any of the bugs you found have patches or merge proposals? If so, do they help?

One possible solution is to look in the product module and see if that record id was changed to something similar and make the same change in the module you’re installing.

Another option is to just remove the reference from the module you’re installing. Depending on how it’s used, that may or may not cause other problems.

Finally, you could create a record with that id for the new module to use. I think all those references get looked up in the ir_data table, so you could create a new record there.
