In my Node.js application, I have set up an endpoint like this:
usersRoute.get('/get', function(req, res) {
//If no date was passed in - just use today's date
var date = req.query.date || dateFormat(new Date(), 'yyyy-mm-dd'),
search = req.query.search;
users.getAllUsers(date, search)
.then(function(results) {
res.json(results);
}, function(err) {
res.status(500).json({
success: false,
message: 'Server error.',
data: []
});
});
});
During testing, I mistakenly named my SQL table, causing it to enter the function(err){} block.
The function within my Service is structured as follows:
function getUsers(date, search) {
return $http.get('/api/users/get', {
params: {
date: UtilsService.formatDate(date),
search: search
}
})
.then(getData)
.catch(handleErr);
function getData(response) {
console.log(response);
return response.data;
}
function handleErr(err) {
console.log(err);
LoggerService.error('Could not retrieve users.', err ,'Oops');
return $q.reject(err);
}
}
Surprisingly, both console.log statements in the then and catch blocks are returning undefined.
If anyone can shed light on why this is happening, it would be greatly appreciated.
Edit For clarification; Here is more backend code:
Users.js
var sql = require('seriate');
var when = require('when');
var getAllUsers = function(date, search) {
return sql.execute({
query: sql.fromFile('../sql/users/getAllUsers.sql'),
params: {
date: {
type: sql.DATE,
val: date
},
search: {
type: sql.VARCHAR,
val: search
}
}
});
}
module.exports = {
getAllUsers: getAllUsers
};
UsersApi.js
var express = require('express');
var dateFormat = require('dateformat');
var users = require('../models/users');
var validation = require('../middleware/validation');
var usersRoute = express.Router();
//Checks for a valid token
validation.isLoggedIn(usersRoute);
usersRoute.get('/get', function(req, res) {
//If no date was passed in - just use today's date
var date = req.query.date || dateFormat(new Date(), 'yyyy-mm-dd'),
search = req.query.search;
users.getAllUsers(date, search)
.then(function(results) {
res.json(results);
}, function(err) {
res.status(500).json({
success: false,
message: 'Server error.',
data: []
});
});
});
module.exports = usersRoute;
In my service, both the then and catch sections are being executed, with both objects (response and err) turning out to be undefined.
