@Nakov I haven't created any policies, and I'm logging in with the admin.
I would like to mention that this doesn't happen in all resources, just in two
@Kris01 so you don't keep any GIT history from when it worked until now so you can compare it? Or compare the code in the resources that it does work and the once that it does not on what you are missing. Or at last share some code, because not seeing what you are trying is also hard to give an answer.
@Nakov when I try do get to the detailed view from the url, since I don't have any buttons shows, it throws a 403 forbidden, but I don't have any gates/policies, so I don't understand where is this coming from, and It only happens when the resource is linked to my user model, to the other models it works fine
I will assign your response as best answer, it helped me find my problem.
The nova documentation says
Undefined Policy Methods
If a policy exists but is missing a method for a particular action, the user will not be allowed to perform that action. So, if you have defined a policy, don't forget to define all of its relevant authorization methods.
