import { Component, OnInit } from '@angular/core';
import { FormControl, FormGroup } from '@angular/forms';
import { AppService } from './app.service';
import { 
  CollectionModel, 
  CrudService, 
  Collection 
} from 'collection';

@Component({
  selector: 'projects-list',
  templateUrl: ['./projects-list.component.html'],
  styleUrls: ['./projects-list.component.css']
})
export class ProjectsListComponent implements OnInit {

  collection: CollectionModel;
  
  getAll() {
    this.collection.reload().subscribe( res => {
      // Send GET request into path '/projects' with default query params 
      // per_page, page, search_query
    })
    
    /*
    For set query params use collection.setParams(key, value),
    
    this.collection
      .setParams('page', 2)
      .setParams('search_query', '1234')
      .search();
    
     */
  }
  
  create(data) {
    this.collection.createItem({ data }).subscribe( res => {
      // Send POST request into path '/projects' with data
      this.collection.search();
    })
  }

  update(data) {
    this.collection.updateItem({ id: data.id, data }).subscribe( res => {
      // Send PUT request into path '/projects/:id' with data
      this.collection.search();
    })
  }

  delete(id) {
    this.collection.deleteItem({ id }).subscribe( res => {
      // Send DELETE request into path '/projects/:id'
      this.collection.search();
    })
  }

  deleteMany(idsArray) {
    this.collection.deleteMany({ ids: idsArray }).subscribe( res => {
      // Send DELETE request into path '/projects' with body data ids: [...idsArray]
      this.collection.search();
    })
  }

  ngOnInit() {
    this.collection.search();
  }

  constructor(private _crud: CrudService) {
    this.collection = new Collection({
      api: this._crud.createEntity({ name: 'projects' }),
      params: {
