如何使用 Sails req.param 函数来检索和更新记录

Question

我试图在sails 1.0 中使用req.param. 函数是徒劳的。我无法缝合检索记录值并将它们预加载到编辑表单上，以便我可以更新记录。下面是我的代码 sn-p。

路线

'GET /organization/:id': { action: 'organization/view-organization-edit' }, 'PUT /api/v1/organization/edit-organization/': { action: 'organization/edit-organization' },

下面是我在 ajax 表单上触发操作的地方

 <td>
                            <div class="col-sm-12">
                                <span class="float-sm-left">
                                  <a style="width: 70px" class="btn btn-sm btn-outline-info" href="/organization/<%= organization.id %>">Edit </a>
                                </span>
                               
                                  <form class= "d-inline" action="" method="post">
                                    <input style="width: 70px" type="submit" value="Delete" class="btn btn-danger">
                                  </form>                             
                            </div> 
......

这给了我网址 http://localhost:1337/organization/1

查看编辑操作

module.exports = {


  friendlyName: 'View organization edit',


  description: 'Display "Organization edit" page.',


  exits: {

    success: {
      viewTemplatePath: 'pages/organization/edit-organization'
    }

  },


  fn: async function (req,res) {

   console.log(this.req.id);

  var organization = await Organization.findOne({ id:this.req.id });// **here is where the error occurs**

    // Respond with view.
    return {
      organizationData: organization, 
      //id:organization.id

    };

  }


};

编辑操作

    friendlyName: 'Update organization',
  
  
    description: 'Update organization.',
  
    inputs: {
      Org_Name: {
        type: 'string'
      },
        
      Org_Level:  {
        type: 'string'        
      }
  
    },  
  
    exits: {
      success: {
        description: "Successful",
      },
    },

  
  
  fn: async function ({Org_Name,Org_Level}) {

    console.log("We are in update function");

    //var org_name= req.body.Org_Name;
    //var org_level=req.body.Org_Level;
    //var id= req.param.id;
    
    console.log(this.req.me.Org_Name);
    console.log(this.req.me.Org_Level);
    console.log(this.req.me.id );
    //console.log(id);

    var valuesToSet = {Org_Name,Org_Level};

    await Organization.updateOne({id: this.req.me.id })
    .set(valuesToSet);

   /* Organization.update({id},{org_name,org_level}).exec(function(err){
        if(err){
          res.send(500, {err: "some error occured"});
        }
        
    
      });*/
    
      return true;  
    }
  
  
  };

Answer 1

In async function you can define req and use it or you can just say this.req.param('id');

  fn: async function ({Org_Name,Org_Level}) {
    let req = this.req;
    let res = this.res;

    console.log("We are in update function");

    //var org_name= req.body.Org_Name;
    //var org_level=req.body.Org_Level;
    //var id= req.param.id;
    
    console.log(this.req.me.Org_Name);
    console.log(this.req.me.Org_Level);
    console.log(this.req.me.id );
    //console.log(id);

    var valuesToSet = {Org_Name,Org_Level};

    await Organization.updateOne({id: this.req.me.id })
    .set(valuesToSet);

   /* Organization.update({id},{org_name,org_level}).exec(function(err){
        if(err){
          res.send(500, {err: "some error occured"});
        }
        
    
      });*/
    
      return true;  
    }
  
  
  };

记录您的 req 变量并检查是否有名称为“body”和“params”的对象。 如果是，您需要使用 req.body 或 req.allParams() 获取它
