You tried using the [] subscript operator on a model instance that does not define _getitem_.

I have to brackets in it

What?

I have no [] in it

😂 Go check out the line the error is traced. It's very clear

{% recursetree category %}

What do those template tag mean?

Then interpreter is always right

Hello guys, please I need help on what to learn to become a full stack web developer using Django, am a self learn beginner programmer and I don't know what to learn, so far I only know basics of python and a little SQL server and also am doing some studies on Django and I know just a little about it, so guys please what should I know or what should I learn to become a full stack web developer 😔😞

from .models import * def add_var_to_context(request): category = Category.objects.all() return { 'category': category, }

A model 'C' has its data given in the form of Fixtures. Many models are dependent on this model through both FK & M2M. Now, in Develop, it has some pk for particular object, while in Prod, for that pk, some different object is set, causing Fixture inconsistency in pk's. To resolve this, in (test db), 1. I tried to alter the schema of child table of C with "ON UPDATE CASCADE" in psql using this https://stackoverflow.com/questions/25973576/updating-primary-keys-in-postgresql., since Django doesn't have on_update=models.CASCADE. 3. I then updated the pk of 'C' objects with the one having in development, in order to avoid Unique constraint failed error, (at this moment, update reflected in Child model) & then reloaded the fixture, it was fine. Some Side effect of this change resulted in "some_model_id_seq" got its value replaced with new one ( because of my Fixture pk change ) My queries are : 1. Is this way the correct to do ?, If so, it won't cause any serious issues ( because of changing pk )? 2. I tried in only one child of C, but there are many more children models of C. So, for them also, I should do manually or any other quick way ? 3. For Child model having M2M, I tried to same Operation in the "Join Table", since that has FK to Parent, it works as expected. Is that ok to do, or any other special change required for it? 4. Is there any other way to solve this ? I'm thinking of having env specific Fixtures ( for Prod, 1 fixture , for Dev, different fixture ). But, it's too much of thing to do.. Changing primary keys is definitely a bad idea, but I don't have any other choice to maintain consistency of 'C' across all env's.. Sorry for the wall of text, since I need to clearly explain what my problem is.

Hi Guyz...Can Anyone Help me to deploy My Django website?

Hi Guyz...Can Anyone Help me to deploy My Django website?

You will need to learn some of the front end technologies as you seem to be versed with the back end already. So get familiar with HTML, CSS, JAVASCRIPT, BOOTSTRAP... these can do for the start, then dive deep into Js frameworks like React or Vue As you proceed to be a full stack you'll need to learn AWS to know how to set your static files especially when deploying them to a host like HEROKU (this is though an optional thing but needed at times) Good luck learning.

Hosting

It's pretty easy. You just have to set up python app on the cpanel

If you're using a string put it in quote. In your above code webpages_list is not a string, it's a variable holding some value so it should not be in quote. access_records is a key name which is a string so it should be in quotes

I was trying using heroku and git and following some utube videos where, they did some changes like changing DEBUG to False, adding heroku to allowed Hosts and creating files like procfile and requirements.txt but I'm always ending with an error in the final page of my website

That'll probably have to do with guicorn... I'm not seeing your code neither do I know what you are actually up to.. I have limited info about what you are doing..
