Fixes #22688

Summary

This PR fixes the improper bindings of the attribute disabled in the project-policy-config.component.html component file.

Overview of changes made

• project-policy-config.component.html

  Fixed all the improper bindings of the attribute disabled in the component, as described in the issue.

   <input 
  -   disabled="!allowUpdateProxyCacheConfiguration"
  +   [disabled]="!allowUpdateProxyCacheConfiguration"
    ...
   />

• project-policy-config.component.ts

  Added logic to change the property allowUpdateProxyCacheConfiguration based on the permissions, since the variable is initialized with a default value false (ref) in the file and the variable is neither used nor mutated.

   private getPermission(): void {
      this.userPermission
          .getPermission(
              this.projectId,
              USERSTATICPERMISSION.CONFIGURATION.KEY,
              USERSTATICPERMISSION.CONFIGURATION.VALUE.UPDATE
          )
          .subscribe(permissins => {
              this.hasChangeConfigRole = permissins as boolean;
  +           this.allowUpdateProxyCacheConfiguration =
  +             this.hasChangeConfigRole && !this.isProxyCacheProject;
          });
  }

To the maintainers @bupd @Vad1mo @chlins @MinerYang,

This will enable only the System Admin to configure Proxy Cache settings, not even Project Admin can configure it.
Should it be configured in such way or need any change in access model?

[bupd]

@vg006 Project admins should be able to configure proxy cache.

[vg006]

Initially the component is configured only to be accessed by the System Admin. But as per your suggestion, I made this change in the component which allows the Project Admin in addition, to access the proxy configuration.

- *ngIf="isSystemAdmin"
+ *ngIf="hasChangeConfigRole"

@bupd Can you review the changes[1][2] once and ensure whether it satisfies the requirements?

[vg006]

@bupd
This branch is rebased on top of upstream's main branch and is now ready for merge.

@vg006 Thanks for your contribution,

you cannot update a proxy cache to normal and vice versa so the checkbox should always be in disabled state.

[bupd]

this should always be disabled, since backend does not allow converting a normal project into proxy cache and vice versa. this should be set to disabled=true indefinitely.

[bupd]

good to go.
