I saw a few questions like mine but couldn't find any solutions that worked so I thought I'd ask.
I'm trying to pull all my data from my database so I can select parts of it in my app. I had my database working fine but when I tried to pull the pictures it failed and keeps giving me this error and also does not seem to receive the data from the database:
TypeError: Cannot read property 'find' of undefined
I have mongoose installed and everything connects so I can't figure out why it won't recognize the find property. My code is below if anyone has any ideas.
// Dependencies
var express = require(express);
var bodyParser = require(body-parser);
var mongoose = require(mongoose);
var exphbs = require(express-handlebars);
var request = require(request);
// var weapons = require(./weapons.js);
// Set mongoose to leverage built in JavaScript ES6 Promises
mongoose.Promise = Promise;
// Initialize Express
var app = express();
// Use morgan and body parser with our app
app.use(bodyParser.urlencoded({
extended: false
}));
// Make public a static dir
app.use(express.static(__dirname + /public));
app.engine(handlebars, exphbs({ defaultLayout: main }));
app.set(view engine, handlebars);
// Database configuration with mongoose
mongoose.connect(mongodb://localhost/weaponsdb);
var db = mongoose.connection;
// Show any mongoose errors
db.on(error, function(error) {
console.log(Mongoose Error: , error);
});
// Once logged in to the db through mongoose, log a success message
db.once(open, function() {
console.log(Mongoose connection successful.);
});
//routes to home page
app.get('/', function(req, res, next){
res.render(index,{ title: 'Express' });
});
app.get('/app', function(req, res, next){
res.render(app,{ layout: 'applayout' });
});
app.get(/all, function(req, res) {
// Query: In our database, go to the weapon collection, then find everything
db.weapon.find({}, function(error, found) {
// Log any errors if the server encounters one
if (error) {
console.log(error);
}
// Otherwise, send the result of this query to the browser
else {
res.json(found);
}
});
});
$.getJSON(/all, function(data) {
console.log(data)
// For each entry of that json...
for (var i = 0; i < data.length; i++) {
// Append each of the weapons' properties to the table
$(#results).append(<img src = + data[i].Picture + />);
}
});
