Solve the fastadmin jump index with parameters can not get the parameters

---

question

We often encounter in development that when accessing the index method, we need to pass a parameter to display the data we have specified with a unified logo.

---

1. Ideas

1. Pass a parameter to index via the URL!
   1) Since the accessed index method is often initiated by ajax, the parameters will not take effect!
2. Add a search condition when ajax is initiated,
   such as $group_id=1

2. Method 1

Use the assignconfig() method in the controller to transparently pass parameters to js

public function index($ids=NULL) //需要从URL接收参数
  {
    
    
      //当前是否为关联查询
      $this->relationSearch = false;
      //设置过滤方法
      $this->request->filter(['strip_tags']);
      if ($this->request->isAjax())
      {
    
    
          list($where, $sort, $order, $offset, $limit) = $this->buildparams();
          $total = $this->model
                  
                  ->where($where)
                  ->order($sort, $order)
                  ->count();

          $list = $this->model
                  
                  ->where($where)
                  ->order($sort, $order)
                  ->limit($offset, $limit)
                  ->select();

          foreach ($list as $row) {
    
    
              $row->visible(['taxState']);
              
          }
          $list = collection($list)->toArray();
          $result = array("total" => $total, "rows" => $list);
          return json($result);
      }
      $this->assignconfig("group_id",$ids); //在这里透传给js
      return $this->view->fetch();
  }

Corresponding to receiving data in js and splicing it into the search conditions

// 初始化表格参数配置
          Table.api.init({
    
    
              extend: {
    
    
                  index_url: 'test/index',
                  add_url: 'test/add',
                  edit_url: 'test/edit',
                  del_url: 'test/del',
                  multi_url: 'test/multi',
                  table: 'test',
              }，
            queryParams: function (params) {
    
     //自定义搜索条件
                  var filter = params.filter ? JSON.parse(params.filter) : {
    
    }; //判断当前是否还有其他高级搜索栏的条件
                  var op = params.op ? JSON.parse(params.op) : {
    
    };  //并将搜索过滤器 转为对象方便我们追加条件
                  filter.group_id= Config.group_id;     //将透传的参数 Config.group_id，追加到搜索条件中
                  op.group_id= "=";  //group_id的操作方法的为 找到相等的
                  params.filter = JSON.stringify(filter); //将搜索过滤器和操作方法 都转为JSON字符串
                  params.op = JSON.stringify(op);
                  >   //如果希望忽略搜索栏搜索条件,可使用
                  //params.filter = JSON.stringify({url: 'login'});
                  //params.op = JSON.stringify({url: 'like'});
                  return params;    
                  
              },

          });

3. Method 2

Without modifying the controller, you only need to modify the parameters when initiating ajax in js

queryParams: function (params) {
    
     //自定义搜索条件
  var filter = params.filter ? JSON.parse(params.filter) : {
    
    }; //判断当前是否还有其他高级搜索栏的条件
  var op = params.op ? JSON.parse(params.op) : {
    
    };  //并将搜索过滤器 转为对象方便我们追加条件
  //将需要的参数group_id 加入到搜索条件中去 要求url传递的参数必须为group_id=XX;可以用 Fast.api.query("group_id")获取到！
  filter.group_id= Fast.api.query("group_id");     
  op.group_id= "=";  //group_id的操作方法的为 找到相等的
  params.filter = JSON.stringify(filter); //将搜索过滤器和操作方法 都转为JSON字符串
  params.op = JSON.stringify(op);
  //如果希望忽略搜索栏搜索条件,可使用
  //params.filter = JSON.stringify({url: 'login'});
  //params.op = JSON.stringify({url: 'like'});
  return params;
},

think

1. Arrays should be used when there are many parameters to pass.
2. There should be feedback if the case is accessed without parameters.
