Currently, I am tackling the permission aspect of my application. The scenario involves developing a Vue application that receives data from a Laravel backend created by another individual. My current challenge lies in determining whether a permission is checked and active under a specific role. In this setup, permissions are associated with roles, meaning when creating a role, it's necessary to identify which permissions are linked to that role.
To start, I retrieve all permissions and organize them into an array structure. This array contains parent permissions along with their respective child permissions, extending up to four levels deep.
The permissions structure is as follows:
{
"data": [
{
"id": 1,
"name": "Suppliers management module",
// Additional permission details...
"children": [
{
"id": 2,
"name": "Suppliers management module settings",
// Additional permission details...
"children": [
{
// More detailed permission information...
"children": [ ]
},
{
// Detailed permission info...
"children": [ ]
},
// And so forth for hierarchy
],
},
// Other hierarchical permission structures...
]
},
// Repeat similar structures for other permissions
]
}
Upon retrieving a specific role, the associated permissions need to be cross-referenced against the entire list of permissions. This comparison helps distinguish existing permissions for the role and those that do not exist within its scope.
The approach taken for comparison involved:
// Initializing arrays for permissions
this.permissions = response.data.data;
// Collating all permissions into one array
this.permissions.forEach((element) => {
this.AllPermissions.push(element);
element.children.forEach((one) => {
this.AllPermissions.push(one);
one.children.forEach((two) => {
this.AllPermissions.push(two);
two.children.forEach((three) => {
this.AllPermissions.push(three);
});
});
});
});
// Storing permission IDs of a role in an array
this.role.permissions.forEach((element) => {
this.permissionsNumbers.push(element.id);
});
// Comparing permissions for role assignment
this.AllPermissions.forEach((item) => {
if (this.permissionsNumbers.includes(item.id)) {
item.check = 1;
} else {
item.check = 0;
}
});
While the above method works, it may appear inelegant due to multiple nested loops and the potential manual adjustments needed if the permission hierarchy changes. Additionally, handling the resulting flat array of permissions tied to a role raises concerns about readability and maintenance.
Exploring more streamlined approaches that retain the hierarchical nature of permissions during comparisons would greatly enhance the efficiency and scalability of this process. Any insights or suggestions on optimizing this workflow while maintaining clarity are highly appreciated. Feel free to seek clarification if any part requires further elaboration.
