Can't run Chapter 7.

[MarkCancellieri]

When I run the Chapter 7 version of the files, I keep getting an error message.

Express

Any idea what could be causing this? (I'm using Windows 8.1, in case that makes a difference.)

Hi Mark,

I would start here:

(C:\Users\Mark_TEST\nodebook-master\nodebook-master\chapter7\models\image.js:16:30)

Specifically line 16. That error typically means that you're running
.replace on a variable or property thats undefined. So if you have an
object of say:

var person = {

name: 'Jason'

};

And you tried to call: person.fullname.replace('Jason', 'Awesome') -
you will get the exact same error (since fullname isnt a thing but
instead should have been called on .name)

If you can post your sourcecode complete somewhere (like GitHub) I can
take a look and help you a little more.

Thanks!

Jason,

All I did was download your source code from GitHub, move to the Chapter 7 directory, run npm install, and then node server. When I went to http://localhost:3300/, that is when I got the error.

I tried the same thing from the imgploadr directory (which is the final app, right?), and I got the same error message.

[shorttompkins]

Hey Mark,

Interesting. I just did the same, cloned the repo fresh, went into
Chapter7 and did npm install && node server.js and it loaded up fine (after
I made sure I was runnign a local instance of mongod that is). Loading the
url pulled up the website fine (although with no content and a bunch of
broken images). Did you try to actually do anything on the site or
literally get that error the instant the site loaded?

I got the error the instant the site loaded. I didn't do anything.

I was following along with the book fine until chapter 7, but it didn't like this replace command from the image model:

ImageSchema.virtual('uniqueId')  
    .get(function() {  
        return this.filename.replace(path.extname(this.filename), '');  
    });  

That was when I tried to download your code, but I couldn't get that to run either.

[shorttompkins]

Im going to try to run this on my other Windows PC when I get home a little
later and see what happens.

Sorry about this. I havent seen this issue before so it has me stumped.

I should get back to you tonight hopefully.

Thanks!

I just tried running imgploadr and chapter7 on my Windows 7 laptop, and they both work (although I had to add the upload and temp folders to the chapter7 version). Very strange. So there is something on my Windows 8.1 desktop that is causing it not to work.

If you can't reproduce the error, it's no big deal.

[shorttompkins]

Very weird. I just tried on a Windows 8 PC and all went well. If anything
I would say maybe delete the repo and try again. Also double check the
version of node you're running on that machine (not that it would be
generating an error like that). You want to be running something along the
lines of 0.10.33.

Sorry I couldn't be of more help!

Let me know if you run into any other snags. Thanks!

Jason,

I figured it out. There was only one document saved to the images collection in the database on my desktop computer, and it was somehow saved without a filename property, which is why it couldn't find the replace method. I deleted that document, and now it works fine.

Thanks for your help, and happy holidays!
