Custom script for update table

Can we write update query to update table fields in JavaScript custom script code .

Never write an UPDATE query, always use the API

You can change what you want in the validate event of your controller.

Hi rmehta

i am trying to update a custom field with salesorder no in Quotation Document when Sales Order is submitted.
Can i use frappe REST API to update this field using “PUT” method. But i am trying to access API through browser then i am not able to find this “Custom Field”.
Can i update custom field of another document using REST API ?

i am executing this code in sales Order Document

quotations = this.cur_frm.doc.sales_order_details;
sales_no = this.cur_frm.doc.name;
$.ajax({
url: ‘api/resource/Quotation/’ + quotations[0].prevdoc_docname,
type: ‘PUT’,
data: ‘name=’ + quotations[0].prevdoc_docname + ‘&sales_order_no=’ + this.cur_frm.doc.name ,
success: function(res) { alert('PUT completed with status ’ + res.status); }
});

data has to be a JSON object string not a query string

Thanks Pratik
But custom filed is not displayed using API. So i am getting this Error.

“NetworkError: 500 INTERNAL SERVER ERROR - http://localhost:8080/api/resource/Quotation/QTN-00004”

Request Error
site: erpnext.erpnext-vm
form: {‘sales_order_no’: u’SO-00026’}

All this error is saying is that system is unable to decode data as json object. Encode data as json string before sending it from client

Hi Bhupesh
i m using this code, yes i understood error but not able to indentify solution.
here “sales_order_no” is a custom field.

$.ajax({
url: ‘api/resource/Quotation/QTN-00004’,
method: ‘PUT’,
data: { sales_order_no: “SO-00001”},
dataType: “json”,
success: function(res) {
alert('PUT completed with status ’ + res.status);
}
}).done(function( msg ) {
alert( “Data :” + msg );
});

Assuming you are using any modrrn browser, replace your data param with following value.

“”"
darta: JSON.stringify({ sales_order_no: “SO-00001”});
“”"

** sorry for brevity, using handheld.
