我用的express为4.13.1，mongoose为4.4.4，而且我跟老师讲的目录结构不太一样，用的webstorm新建的nodejs项目在录入页post后出现如下错误：_movie.save(function(err, movie){
^
TypeError: Cannot read property 'save' of null这是我出现错误的代码位置：//admin post movie
router.post('/admin/movie/new', function(req, res){
var id = req.body.movie._id;
var movieObj = req.body.movie;
var _movie;
if (id !== 'undefined'){
Movie.findById(id, function(err, movie){
if (err){
console.log(err);
}
_movie = _.extend(movie, movieObj);
_movie.save(function(err, movie){
if (err){
console.log(err);
}
res.redirect('/movie/' + movie._id);
});
});
}else {
_movie = new Movie({
doctor: movieObj.doctor,
title: movieObj.title,
country: movieObj.country,
language: movieObj.language,
poster: movieObj.poster,
year: movieObj.year,
summary: movieObj.summary,
flash: movieObj.flash
});
_movie.save(function(err, movie){
if (err){
console.log(err);
}
res.redirect('/movie/' + movie._id);
});
}
});var mongoose = require('mongoose');
var MovieSchema = new mongoose.Schema({
title: String,
doctor: String,
language: String,
country: String,
summary: String,
flash: String,
poster: String,
year: Number,
meta: {
createAt: {
type: Date,
default: Date.now()
},
updateAt: {
type: Date,
default: Date.now()
}
}
});
MovieSchema.pre('save', function(next){
if (this.isNew){
this.meta.createAt = this.meta.updateAt = Date.now();
}else {
this.meta.updateAt = Date.now();
}
next();
});
MovieSchema.statics = {
fetch: function(callback){
return this
.find({})
.sort('meta.updateAt')
.exec(callback)
},
findById: function(id, callback){
return this
.findOne({_id: id})
.exec(callback)
}
};
module.exports = MovieSchema;var mongoose = require('mongoose');
var MovieSchema = require('../schemas/movie');
var Movie = mongoose.model('Movie', MovieSchema);
module.exports = Movie;求大神们帮忙！！！
