Node.JS / Mongoose / Express -> Object has no method "findAll" - model-view-controller

Question

I'm trying to pass a method from my model.js to my route.js.. And my route doesn't find any method ! I searched a solution and tested a lot of codes, without success.
I'm a beginner in Node so sorry if it's a stupid error.
This is a part of my code :
Route.js
var mongoose = require('mongoose');
var membersModel = new require('../models/MemberModel');
// Member list page
exports.list = function(req, res){
membersModel.findAll(function(err, docs){
res.render('list.jade', { title: 'My Registration App - Member list', member: docs });
});
};
MemberModel.js
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
ObjectId = Schema.ObjectId;
// Open DB connection
var MemberSchema = new Schema({
id : ObjectId,
title : { type: String, required: true, enum: ['Mr', 'Mrs', 'Mme', 'Miss'] },
lastname : { type: String, required: true, uppercase: true, trim: true},
firstname : { type: String, required: true},
mail : { type: String, trim: true, index: { unique: true, sparse: true } },
date : Date
});
// ...
MemberSchema.method.findAll = function (callback) {
Members.find(function (err, member) {
callback(null, member)
});
};
var conn = mongoose.createConnection('mongodb://localhost/members');
var MyModel = conn.model('Members', MemberSchema);
var instanceMember = new MyModel;
module.exports = instanceMember;
Thanks for the time passed helping me.
If you want other informations, tell me !

Answer 1

I think you have a few problems here:
Your schema's instance methods should be defined on MemberSchema.methods (not .method).
A method like findAll that returns instances should be defined as a static method of the schema (on MemberSchema.statics) instead of an instance method.
You should be exporting MyModel, not a new MyModel instance of it as you are now. module.exports = MyModel;
route.js should not be using new in its require as you want the MyModel class to be available to the file, not an instance of it.

Answer 2

for the find function the syntax usually is
<modelname>.find({conditions},function(err, results){
//use the results
});
and if u don't have any specific conditions and want to find all, you can just give empty object in the conditions {}
<modelname>.find({},function(err, results){
//use the results
});
and for the schema, an example
const articleSchema = {
title: String,
content: String
};
// to create a new model named Article
const Article = mongoose.model("article",articleSchema);
