Hi, please try console.log(tlb.name)

3

@SwitsolAG when i tried using tlb.name i get an error

VM7751:117 Uncaught TypeError: Cannot read property ‘name’ of null(…)

4

hmmm, sorry it’s very strange everything works on my side.

5

@SwitsolAG where did you wrote the script

i wrote it in the student_applicant_list.js file

6

frappe.model.get_doc() will only return Student Batch record if it has loaded in the locals otherwise it will return null

7

@makarand_b so i can use this code only on student batch doctype page not in student applicant?

8

@makarand_b @SwitsolAG okey can you help me show how can i get details of student batch App Builder-TEST BATCH-2017-18 with out using locals

9

I suppose frappe.model.get_value("Student Batch",batch name, field_name) or using frappe.call

10

also gives me null

so i decided to do the frappe.call

@SwitsolAG @makarand_b thanks for your help

and i can’t see tick option which sets this as solved

You might have been using an async method. This is the proper way to do it within the .then()

// get doc by name
frappe.db.get_doc('Task', 'TASK00002')
    .then(doc => {
        console.log(doc)
    })

// get doc by filters
frappe.db.get_doc('Task', null, { status: 'Open' })
    .then(doc => {
        console.log(doc)
    })
