I have added this 2 access rights in my ir.model.access.csv but they are not working, a user that have group_mining_user user group still can modification products, where is the problem? or have can I achieve this?
my ir.model.access.csv is loaded correctly as other access rights are working
access_product_product_mining_user,product.product.mining.user,product.model_product_product,group_mining_user,1,0,0,0
access_product_template_mining_user,product.product.mining.user,product.model_product_template,group_mining_user,1,0,0,0
Did you added these group_mining_user to your user?
yes i did
Take into account that rights for products is granted for many users groups (depending on the set of installed apps): sales persons, warehouse users, purchase users, etc. Your rule ADDS the right for the mining users, but does NOT FORBID it for other groups. In order to achieve you goal you should overwrite each access rule in your database which grants rights for products.
Also there is a ready solution for that purpose - https://apps.odoo.com/apps/modules/12.0/product_access_restriction/
