Collapsible product categories in website shop causing NoneType error

[beergirlatl]

I have successfully installed the module (without error) to create collapsible categories in the webshop, but when I navigate to the Customize menu and select the check box, the shop page shows this error.

I am suspecting that this is some sort of null data error, but not sure where/what might be missing? I have many categories with parent categories, and every product in the system has a public category defined.

Any suggestions on where to look would be much appreciated.

Oh, I am running odoo on Windows 8 and despite the file structure I am current up to the odoo_8.0.20150625 build.

Error Error message:

"argument of type 'NoneType' is not iterable" while evaluating "'fa-chevron-down' if categ.id in parent_category_ids else 'fa-chevron-right'" QWeb Error message:

Could not evaluate expression "'fa-chevron-down' if categ.id in parent_category_ids else 'fa-chevron-right'" The error occured while rendering the template website_sale_collapse_categories.option_collapse_categories_recursive and evaluating the following expression: 'fa-chevron-down' if categ.id in parent_category_ids else 'fa-chevron-right'

Try to reproduce the problem in one instance of runbot: https://runbot.odoo-community.org/runbot/repo/github-com-oca-website-186, and tell us the sequence, because I haven't get that problem. Have you customized something (theme, code...)?

[beergirlatl]

I haven't customized anything myself. Just trying to set up the website at this point, however I did notice that I have a few more modules installed, like Point of Sale, Accounting, Projects, etc.

[pedrobaeza]

Please try in the link above if you can reproduce the problem. If then, please write down the followed steps.

[beergirlatl]

I have not been able reproduce the problem in your instance. In my own instance I have deleted all Public Categories and the Shop loads without generating the error. However, when I create a Public Category and navigate back to the Shop, the error reappears, even if I haven't added the Public Category to any product records or changed anything else. It looks like there are some permission differences between your instance and mine on the product.public.category model, namely that my instance looks to be requiring the "name" field and makes "__last_update", "complete_name", "display_name", and "id" Readonly whereas your instance shows nothing required or readonly (including screenshots). Do you think it is possible that this could be contributing to the problem or is there another module that might have altered these settings that I should install or uninstall?
Any guidance would be greatly appreciated.

Sorry, but we need that the bug is reproducible in our side, so I close meanwhile.

[Snarfbox]

Hello, I have the same problem. I'm on Ubuntu with the last versions of odoo8

[shahid-malik]

Anyone got the solution of the problem ?

[gonxi]

in my case the problem is solved moving the website_product_filters module from vauxoo out of addons path. (this module was donwloaded from "Apps in line") https://apps.odoo.com/apps/modules/8.0/website_product_filters/ is possible that you have this module?

[treviser]

The problem exists in all versions from 8.0 to 11.0 and this happens when the module website_product_brand module is installed together with collapsible/expandable categories. Somebody with a kyrillic name has posted a comment on the App store page where he assumed that this happens because of inheriting the same controller, see his comments here: https://apps.openerp.com/apps/modules/8.0/website_product_brand/ If I deactivate the option for expandable/collapsible categories in the shop page, website_product_brand works perfectly. Is there anything which can be done about it?

[pedrobaeza]

I don't think the problem is in versions >v8, as the feature is integrated in core, with no multiple inheritance. For v8, the only way I see is to add a glue module.

I have just encountered this issue in v12. Anyone found a permanent solution yet?
