Disable <ma-switch

[Phillip Weeks]

Is there a way I can enable or disable a <ma-switch control using an expression such as user permission

Sure there is, look in the forums and you have a lot of information based on what object has permissions variable. i.e
one can use User.current variable to see what user has been logged in and its options.

Example:

{"username":"admin","email":"admin@admin.net","oldHashAlgorithm":false,"grantedPermissions":["excelReports.fileStoreWritePermission","graphical.view.addView","internal.status","action.purgeAllPointValues","SNMP_MIB_STORE_READ","alarms.view","reports.view","graphical.view.upload","filestore.user.create","permissionDatasource","action.log4jUtil","excelreports.view","legacypointdetails.view","graphical.view","filestore.docs.read","dataFileDataSourceREST","watchlist.view","haystack.server","action.noSqlBackup","action.noSqlRestore","mailingLists.create","action.purgeAllEvents","datapointdetails.view","users.view","action.purgeUsingSettings","action.sqlRestore","action.excelReportPurge","SNMP_MIB_STORE_WRITE","filestore.docs.write","filestore.public.write","pointlinks.view","action.configurationBackup","action.reloadLinks","dataImport.view","filestore.core.read","action.reportPurge","permissions.user.editSelf","jsonData.create","permissions.superadmin","filestore.core.write","action.sqlBackup","excelReports.fileStoreReadPermission"],"sessionExpirationOverride":false,"sessionExpirationPeriod":null,"lastLogin":"2019-09-26T17:10:17.653+03:00","lastPasswordChange":"2019-04-17T11:15:25.795+03:00","validationMessages":null,"password":"","phone":"","disabled":false,"homeUrl":"/ui/administration/home","receiveAlarmEmails":"IGNORE","timezone":"","systemTimezone":"Europe/Tallinn","admin":true,"receiveOwnAuditEvents":false,"systemLocale":"en-US","passwordLocked":false,"muted":true,"id":1,"permissions":"superadmin","locale":"","name":"Administrator","originalId":"admin"}

You can see that it has permissions variable. You can use this with ng-disabled directive of an md-switch to something like this

<md-switch ng-disabled="User.current.permissions !== 'superadmin'" ng-model="myPoint.valueFn" ng-model-options="{getterSetter:true}"></md-switch>

This switch is disabled if user does not have superadmin permissions. One can also leverage the ID of an user and use it like this so that you would not have to explicitly set the permissions to your required user.

Cheers,

Thanks @ThomasEinasto , very close.

I would suggest something more akin to this (as of Mango 3.6.x)

ng-disabled="!User.current.hasAnyRole('superadmin')"

This will work even if the user has multiple roles assigned.

I wanted to copy this response from years ago by you which I found by search but as Mango has changed over the years this was not working anymore.

@jared-wiltshire said in User permissions to view pages:

@shaun
Phillip's post contains a lot of useful information. As he has indicated the best way to restrict users from seeing data they should not be seeing is to set the permissions on the data points and on the JSON store objects.

However it is also very useful to hide certain navigation links inside your app so your users can't navigate to a page that they will not be able to access any data on. This can be done for menu items by adding a permission property to an object in the MENU_ITEMS array. If you need to hide something in the content of your page you can add a ng-show or ng-if directive, e.g. ng-show="user.hasPermission('superadmin')"

But as Mango has changed over the years this function was not working anymore :), hence why I tried to provide the best solution I could leverage.

Honestly I appreciate it.

hasPermission() should still work but is deprecated and will print a warning to the console.
