Can not update the arrays from the put endpoint
0
This is one simple api using express where the results are stored in a course array. The validation logics are stored into the validateCourse function.
Now the problem is the POST endpoint is working correctly but while I'm trying to update through the PUT endpoint i'm getting 404 error:
name is required.
Can anyone tell me where is the problem in the logic or the PUT endpoint thus the update option is not working.
const Joi = require('joi');
const express = require('express');
const app = express();
app.use(express.json());
const courses = [
{ id: 1, name: 'course1' },
{ id: 2, name: 'course2' },
{ id: 3, name: 'course3' }
]
app.post('/api/courses', (req, res) => {
const result = validateCourse(req.body);
// console.log(result);
if (result.error) {
res.status(400).send(result.error.details[0].message);
return;
}
const course = {
id: courses.length + 1,
name: req.body.name
};
courses.push(course);
res.send(course);
});
app.put('/api/courses/:id', (req, res) => {
//Search course by get method
//If not found return error 404
const course = courses.find(c => c.id === parseInt(req.params.id));
if (!course) res.status(404).send('not found with the given id');
//validate
//if invalid ,return 400 bad request
const result = validateCourse(req.body);
// const {error} = validateCourse(req.body);
if (result) {
res.status(400).send(result.error.details[0].message);
console.log(result.error.details);
return;
}
//if valid then update course
//Return the updated course to client
course.name = req.body.name;
res.send(course);
});
//INPUT VALIDATION//
function validateCourse(course) {
const schema = {
name: Joi.string().min(3).required()
};
return Joi.validate(course, schema);
}
