str(item.text) because your text in the models is char type and not string, so it has to be converted to string to be able to load properly on the browser. I know it's too late now, but I hope this helps people who learn by watching this video. I really love all your videos, you are very good at explaining. I came from old fashioned PHP frameworks and want to learn django. I'm glad I make a good decision, python is great and versatile. Back end front end, it can do anything.
As someone below mentioned, I also got an error when trying to run 'python manage.py makemigrations main' I simply had to change max_Length to max_length (lower case 'l') this worked. Thank you for the comment below.
For anyone else noticing this: The lower-case "L" in sublime text looks like upper-case when in keyword format. Tim did type "length" in lower case, but it just looks like upper case. The font was probably made in order for the user to be able to distinguish variable names from normal text, not for tutorial purposes.
Hi Time. I would like to thank you for this awesome tutorial. I "know" how to "make things work" in Django, but your tutorial is explaining the WHY. Thanks bro.
yeah it's complicated, to understand, you should know that the 'items' he got are saved in the sql database. So basically when you type a name in the url bar, that name will be passed to the index func and it will response by 'printing' the item text. Sorry if i am not much clear, I'm not an expert and I dont' know if I'm getting wrong with something.
@@zlls Yeah but the name is not directly passed to the index; when you type a parameter (127.0.0.1:8000/) in the url bar and press enter, first django search that parameter inside /main/urls.py (), if is founded search the function asociated ( views.index ), which is stored inside main/views.py ( def index(): ) and last run that function
Tim said that he is going to use SQLite3, but I have no idea where he used it. I don't even see him typing anything about the word 'SQLite'. Can anyone explain it for me?
I think you should give more context to your explanations. Would be good if you could briefly zoom out onto the Django architecture and file system and then zoom in into details.
Hey, i am facing an issue. In my item_set.get(id = 1/2/3), an error always pops up telling me that there is no matching item. But when I search for it using the name = '', it works as it should. If anyone else is facing this issue and knows why this is happening, please let me know. Thanks
@Tech with Tim at 13:31, I tried listening to it multiple times the reason that you said why t.item_set.all() doesn't throw error but it just doesn't make any sense, could you please explain in simpler words here in comments PS: Great video!
The item_set function returns a list of all the items belonging to a particular “parent” object. In this case the parent object is the todo list and one of its items happens to be an object called Item. I think the wording in this specific scenario is a bit tricky since both the function name and the object name both share the name “item”, but they are not related.
Guys, item_set is NOT a keyword. Just part of it is. Tim has two models named ToDoList and Item. That Item model's name gets lowercased and added to _set. So it will become item_set. If the model's name were Car, then the set would be named car_set. Set is created when you indicate that the model is in relationship with another model.
When I type to command line "python manage.py makemigrations main" I get this error: __init__() got an unexpected keyword argument 'max_lenght'. I checked everything maybe three four times but I still don't know how to fix it.
Isn't it much easier and less time consuming to just create an app to use inside the pre-built Django admin area and add queries to the db from there? Ive used both methods and i make alot of typos so honestly adding queries in the shell can be frustrating. Plus with an app you dont need to write the lines of code everytime in the shell as everything is easily modifiable from the admin GUI. Anyway, just a noobs idea here. Probably smth i'm overlooking.
I've followed along with every step and went back to verify everything is typed correctly. I'm at 17:54, and I'm getting an error screen when I put in /(insert any number) ---- as in literally placing any number there. TypeError at /1 index() got an unexpected keyword argument 'id'

hi! i'm getting an attribute error during t.item_set.all(), can someone tell me why it doesn't work for me when i have done the exact same thing as Tim did? :(
I just got and solved an issue with the 'max_Length', it should be in the lower key right? so I wonder how did you not face an error when you make migrations for the main app?
hello, dont we have to do 1. python3 manage.py makemigrations webapp 2. python3 manage.py sqlmigrate webapp 3. python3 manage.py migrate webapp ??? thxz alot Lisa
When a type migrate it tells me that i don't have a virtual environment Do you know why ?? And when i type activate dj it tells me 'could not find conda environment: dj'
okay then create a virtual environment, activate it and try: $ conda create -n dj python=3.6 $ activate dj $ python manage.py migrate (don't include $)

Hey you just make a mistake or some thing else because in this what you thought it's not plzz make what you put on the mysite urls section plzz it lots of confusion 😊
Finished creating the models file, typed python manage.py makemigrations main and I get a reply back, 'no installed app with label 'main'. when I do python manage.py migrate, it says Apply all migrations: admin, auth, contenttypes, sessions. I even spent considerable time double checking my spelling and it is correct. Any ideas on how I can fix it?
Got me also. Tim should refer to his django setup tutorial: techwithtim.net/tutorials/django/setup That is where he does the Python "manage.py startapp main" and that creates the main.
For people reading in the future, I had that problem because I didn't save the settings.py file. After adding 'main.apps.MainConfig', to the settings file it somehow updates for Tim without saving. For me each change that I make I have to save it and then run the cmd command again and it works.
Everything works except items = ls.item_set.get(id=1) --> error "Item matching query does not exist" however, if I do, items = ls.item_set.get(text="this text") it works. Don't know why.

please my ToDoList is indicating an error, "ToDoList has no objects".
ls = ToDoList.objects.get(id=id)
Solution for using Visual Studio Code:
1. Ctrl + "," (comma)
2. Extensions --> Python --> Linting --> Enable Linting (chosen)
3. Linting Pylint Path: python_django
4. Save & Enjoy
Before this you must install package: python3 install pylint-django (or python install pylint-django)

PS: Great video!
Btw he wasn't talking about why it didn't throw any error. He was just explaining that each ToDoList has a set of Items.
The item_set function returns a list of all the items belonging to a particular “parent” object. In this case the parent object is the todo list and one of its items happens to be an object called Item. I think the wording in this specific scenario is a bit tricky since both the function name and the object name both share the name “item”, but they are not related.

it should be max_length() I think
the L in the max length should be lowercased
I'm with the same error, I didn't find nothing wrong. Could someone help me?
Hi friend, I solved it, you wrote the word 'length wrong. Check it out.
my item_set.all() doesnt work
same here
Did you got it right
When i do
" ToDoList.object.all()"
The output is
Instead of object name, did i do something wrong ?
