Python Django Tutorial: Full-Featured Web App Part 5 - Database and Migrations 

Thanks!

Did you succeed?

me, too

I completely agree these tutorials are excellently put together. I have taken classes elsewhere and they are either too slow or too fast. Corey's pace and how he describes what is going on is outstanding throughout!

@@quasa0 lol

leave alone afford, how about understand it too hahaha. This videos are great

have to like this comment for the clever import statement

import love love.more()

@Anoop Janakar I'm glad :D

love.objects.all()

Thanks, Quan! I appreciate the comment

World is going through pandemic, and we both are learning django!

me three bradah

@@complex1511 ok, counter += 1 BTW great content here in this playlist... 👍

@@agentNirmites LOL increment the counter by 1.

@@shashanksharma7242 ok, my database says 5, is it correct ? I am using firebase 😂

Watching this from Kazakhstan. First I tried to look up some good tutorials on the Russian youtube but they all were bad. Then decided to go on English youtube and found that gold.

Thanks! Glad you’re enjoying the series!

Thanks! Glad you’re finding the videos helpful.

I agree with you cause I've been using PHP for a long time too, but Python and Django makes life easier for web apps, especially with an outstanding teacher like Corey

Agree, I've been using PHP for a long too. Now I am shifting to python and Corey's tutorial is the beast. I've followed enough python tutorial, read book but his tutorial best among others.

Bro, php is bad.

@@prettycode4028 Developing web apps with raw php is bad yeah, but working with frameworks like Laravel and CI makes it more easier. Though have to say, Python and Django just makes it more easier.

That's the reason I'm watching 5 years old playlist.

I was also having a lot of difficulty until I downloaded a program that displayed the database contents onto a GUI. The thing that really threw me was how django refers to tables as models rather than as tables. Once I understood that we were just creating a new table inside of the database called (projectname_post) it all began to make a lot more sense.

having some database knowledge really helps here

Your app must be installed first (inside the settings.py) In our case you'll include 'blog.apps.BlogConfig' in our INSTALLED_APPS tuple inside settings.py

Thanks so much! That’s such a big help and I really appreciate it!

How has it gone?

Thanks!

check out the durgasoft python and django course

Thanks!

Laravel is sweet, but man I love python so much more than PHP

thanks man, i was actually wondering what ipython is, now i know!

@@lardosian no problem! ipython is really great to use

Thank you very much for the tip Mr Leaf. It feels and looks significantly better using ipython in the shell.

Thanks for the tip mate !

Thanks!

You sir are a lifesaver stuck on this forever till I decided to check the comments and found this!

I love you!!!! It took so long to solve this issue

I think his computer uses the AM/PM system. Doesn't rule it out, though

django defaults to the utc timezone so he could have been in a different timezone

Switch to Python Shell --> (django_env) E:\Projects\django_env_project>python manage.py shell Python 3.7.0 (default, Jun 28 2018, 08:04:48) [MSC v.1912 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole) will result in error if you call before importing Post >>> Post.objects.all() class Traceback (most recent call last): File "", line 1, in NameError: name 'Post' is not defined >>> from blog.models import Post is giving me one result as I executed one already >>> Post.objects.all() >>> from django.contrib.auth.models import User >>> User.objects.first() Storing the user details in variable for passing in Post() class >>> var2 = User.objects.first() Storing the Post() obj to >>> post_2 = Post(title ='blog2', content ='Second post', author = var2) a variable post_2 When you call you will get no results in my only one result instead 2 >>> Post.objects.all() because you need to save the data to the database >>> post_2.save() >>> Post.objects.all() Now you see two results

OMG thank you so much!! Very helpful comment

To make it clear for everyone who has this issue .If you get this issue > Post.objects.all() this line instead of , then you should add objects = models.Manager() to models.py file - below author = models .

mine gives the same error even after doing that so no idea what ive done wrong lol

thanks so much. this was very helpful

@@barsonik3855 same, did you find a solution for it?

shittt... I missed it. wish I could be here before 10 mil

thank you soooo much i wasn't able to pass that point.

what do you mean?

@@jschvach He means the default view can have just the date without the time, but if you put your mouse pointer on the date text, then a small window can appear showing the time as well.

I think it relates to the User table ids'. Since there is a foreign key in the Post table, the author_id shows the id reference for each user. Author_id is created automatically once a one-to-many relationship is made. I guess thats how it works

@@stanleyjohn4670 This was also confusing to me at first, by using author_id and assigning that to user.id , it essentially marries the user.id to a post....when you use the _id, django knows you want to associate this with a specific foreign key. There are also other ways to do this BUT Corey had already run a query to extract the user and assigned it to the variable - user...

@@mrmuranga Well. this is just one way of doing it. So choose what's comfortable lol

Since author is a ForeignKey to the Post model, Django knows to expect a User object. It just automatically adds the option to add the id for that foreign key also. So Django added that in the background. FROM COREYS ANSWER WAY BELOW >>> NOT MINE

Ah thanks! Best of luck!

Corey hoping you make it in google and he gets instant 2k in a day xD. Excellent series btw, if I ever get a job based on all this, I'll definitely pay as well, also a suggestion, do a good Django REST framework series, understanding API is proving to a challenge for me, I'm sure your series would help, me and countless others.
