It should be yes using conditionals, the documentation for that isn’t released yet but I can provide the prototype here (this may be subject to change when we release I18N):

Using RBAC conditions

Adding a new condition

​
In your bootstrap file located in ./config/functions/bootstrap.js you can do the following:
​

const conditions = [
  {
    displayName: "Entity has same name as user",
    name: "same-name-as-user",
    plugin: "name of a plugin if created in a plugin"
    handler: (user) => {
      return { name: user.name };
    },
  },
];
​
module.exports = () => {
  // do your boostrap
​
  strapi.admin.services.permission.conditionProvider.registerMany(conditions);
};

​

Condition

​
A condition have 4 possible properties:
​

  • displayName: name showed in the UI
  • name: technical name. Should be kebab-cased
  • plugin: If you create a plugin condition add the plugin name. e.g content-manager
  • handler: A function (sync or async) that returns a condition object. Read more here
    ​

Handler

​
The condition handler receives the authenticated user making the request.
​
It should return oneOf:
​

  • true:
    ​
    Returning true means the condition will always match.
    It is usefull if you want to verify an external condition or a condition on the authenticated user only.
    ​
    const condition = {
  displayName: "Can drink",
  name: "can-drink",
  async handler(user) {
    if (user.age > 21) return true;
    return false;
  },
};

​

  • false:
    ​
    Returning false means the condition will never match.
    It is usefull if you want to verify an external condition or a condition on the authenticated user only.
    ​
    const condition = {
  displayName: "Can drink",
  name: "can-drink",
  async handler(user) {
    if (user.age < 21) return false;
    return true;
  },
};

​

  • Condition object:
    ​
    A condition obect is an matcher object that will allow verify conditions on the entities you read, create, update or delete.
    ​
    We use sift.js behind the scenes to do the condition matching. Here are the list of allowed operators:
    ​
    • $or
    • $eq
    • $ne
    • $in
    • $nin
    • $lt
    • $lte
    • $gt
    • $gte
    • $exists
    • $elemMatch
      ​
      Examples
      ​
    const condition = {
  displayName: "price greater than 50",
  name: "pricate-gt-50",
  async handler(user) {
    return { price: { $gt: 50 } };
  },
};
