Entity Framework 6: Pull in Child Entities with Async WebAPI 2.0

    Just a quick piece of code to get all the children under a given parent. The solutions is pretty straight forward but took sometime to think about since I wanted to keep the result asynchronous. I was also thinking of how I would use scaffolds creates other apis with my models.

Code:

db.Product.Include(x=>x.ProductChildren).SingleOrDefaultAsync(x => x.Id == id);

Notes:
    Its late at nite (so no judging...) but I wanted to get my thoughts down and explore this code for a bit. The piece code is async but my question is does it pull the child entities after it has filter down on the parent id? Or does it pulls in all the children before it has filtered down on a particular partent id and if not wouldn't a more proper way to do it be more something like...

db.Product.FindAsync(id).Include(x=>x.ProductChildren);

This code doesn't work of course, since the Include doesn't exist for 'FindAsync' but either way alternative I believe might be with the 'ContinueWith()' method which I haven't had a chance to look at.

Mongodb Cheatsheet

This cheat sheet is based on the latest version of mongodb, which initial had setup and didn't encounter any problems. However that all changed when I was working remote and forgot I disabled the port no my network, rather than with the server. So I went pointing around where I didn't need to and ended up messing things up. The Best tutorial out there is of course on digital ocean for my setup on ubuntu 16.04 , this articles isn't so much about getting setup. I just wanted to include it because I found myself looking back at it to see if I missed a step. Bugs/Problems Now comes all the messed up things I found and had to deal with. firewall - Port seems to be open, but connection refused try using 0.0.0.0 in the bin_ip for the /etc/mongo.conf try sudo ufw disable and check to see if it works without the firewall (probably still wont but worth a shot), then just sudo ufw enable. Make sure port 27017 is open. Then check this  linux - Connection refused to MongoDB e...

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loo...
