import { Ability } from '@casl/ability';
import { Injectable } from '@nestjs/common';
import { AccessService } from 'nest-casl';
import { AbilityFactory } from 'nest-casl/dist/factories/ability.factory';
import { AuthedUser } from './jwt.strategy';

@Injectable()
export class ConditionsService {

  abilityFactory: AbilityFactory;

  constructor(
    private accessService: AccessService,
  ) {

    // find the a ability factory (hacky method)
    // https://github.com/getjerry/nest-casl/issues/198
    this.abilityFactory = (this.accessService as any).abilityFactory;

  }

  getConditions(user: AuthedUser, action: string, subject: any) {

    const userAbilities = this.abilityFactory.createForUser(user, Ability);
    const relatedRules = userAbilities.rulesFor(action, typeof subject === 'object' ? (subject as any).constructor : subject);
    const conditions = relatedRules.map((rule) => rule.conditions);

    return conditions;

  }
