Transforming JSON-like data into a string, node mysql

Question

Quick edit - I am a complete beginner in web development, so I realize the solution might be stupidly obvious.

I'm attempting to insert a data set into a MySQL db through nodejs/expressjs/mysql.

I have a successful connection to the db and can query from it without issues.

Here is my post code:

app.post('/pyme', function(req,res){
    console.log("Data being POSTED to db...");
    var post = req.body;
    console.log(post);
    var sql_insert_pyme = 'INSERT INTO pyme(NombreComercio,NumeroTelefono) VALUES =?';
    sql.query(sql_insert_pyme,post,function(err){
    if(err) throw err;
    });
});  

The POST data I am getting looks as follows:

{ NombreComercio: 'Sebastian Avila',
  NumeroTelefono: '71021714' }

I need a method to break that post into a simple:

"'Sebastian Avila', '71021714'"

Basically I want to end with:

post = "'Sebastian Avila', '71021714'"

Answer 1

You need to reduce a JSON object to an array (you can reduce it to string straight away, but array gives you more control over) and join it.

 var postObject = { NombreComercio: 'Sebastian Avila', NumeroTelefono: '71021714' } var postArray = Object.keys(postObject).reduce(function(reduced, jsonKey) { reduced.push("'" + postObject[jsonKey] + "'"); return reduced; }, []); var postString = postArray.join(','); console.log(postString); 

If you want query parameters to be dynamic, you can as well set Object.keys(postObject).join(',') in columns names part of the query.

Try this

  var postObject = { NombreComercio: 'Sebastian Avila', NumeroTelefono: '71021714' } var vals = Object.keys(postObject).map(function(key) { return "'"+postObject[key]+"'"; }); console.log(vals.join(','))
