Re: reg: django Model for MCQs type project

[Yoo]

Have a Test model which as a unique identifier (BigAutoField). Get a Questions 
model with a foreign key to a test and a charfield for the question itself (you 
can add BrinIndex for optimization). You can add a booleanfield if the question 
is optional and whatever else you need (like the correct answer letter). Get an 
Answers model with a foreign key to a specific question. This is the most 
efficient.

You say you don’t need authentication, but it looks like students need some 
kind of it... BUT there is an alternative. If the student doesn’t have to fill 
out their name, then, using paths, you can show the student a URL that is 
connected to a record on another model. 

It could look like this: example.com/test/3?completed=846

With the path of completed=846, a view can query this new model, we’ll call 
Completed, that has the following attributes (columns): id (BigAutoField) and 
Your_Answers (ArrayField/JSONField Both PostgreSQL only). The view does a query 
on the test (test 3) to show and now also has data from the Completed table at 
the row with id=846.

Just to open your mind up to another world WHICH IS NOT EFFICIENT AND NOT 
PRETTY TO IMPLEMENT SO PLEASE DO NOT DO IT... You could also try it with 
PostgreSQL’s JSON attribute. Just make a test model which includes a unique 
identifier and a json field. The JSON field would just have keys be the 
question number (1-10) and then a... nvm here’s an example of a piece of json.

{
  1: {“question”: “What is your name?”,
   “answers”: [“blah1”, “blah2”, “blah3”] }
   2: {“question”: “What is your ethnicity?”,
   “answers”: [“blah1”, “blah2”, “blah3”] }
}

You could also try it NoSQL style with MongoDB. Each document is a test with a 
unique identifier
Good luck!

Re: Problem trying to use postgresql and psycopg2 in a django project

[Yoo]

Hey, I think for OSX (Mac) or anything using the Darwin OS (basically apple) 
has to use psycopg2’s binary. Just install psycopg2-binary and it should work.

Re: Django authentication best practice

[Yoo]

Whenever I deploy an app, I always use cookiecutter-django. I’m pretty sure 
there is an option lying somewhere in the settings that let you disable 
username. If not, I believe the BaseUser model has the option of the unique 
identifier or username be set to the email itself.

Otherwise, you can do what you said, which is abstractbaseuser model. Or you 
can setup a manager class. Check the Django source code for a little more 
insight.

Re: Correct Design: one app depending on another app

[Andrew C.]

I’m not sure what you mean by content management, so I’m gonna take a
guess: website builder like Weebly or Wix. You need a NoSQL database,
completely unstructured data. Kind of like a crime file drawer with folders
dedicated to each case and all its evidence. Some folders only have one
piece of evidence and others a whole lot, right?

By the looks of it, you’re making some revolutionary Weebly or Wix or
whatever with some custom features. If so, here’s what I’d recommend:

1) Read up on how jinja is developed. Jinja is the templating thing we use
in Django, for example: { if user.is_authenticated}
This will help you layout each individual website.

2) Use an unstructured database, like MongoDB or Cassandra. I almost always
tell people you should never have to use a NoSQL db, but in your case, it
might work. Take MongoDB’s document-based schema: each document belongs to
a single website. Within each document would be the site’s content using
keys as a way to input the key’s values on to the website (hopefully that
makes sense) using a jinja inspired template.

The thing I’m confused about is your media app. So I’m gonna guess again
and hopefully you can clear it up for me if need be. If not, still lemme
know.

Let’s say — I’m imagining a website builder like Wix and Weebly right now
btw — that a user drags some music container onto his/her website. The user
adds music and stuff via a different app? I don’t think that’s necessary
unless you code this part in C (for finding the files. Read on for what I
mean).

If you’re not using AWS with cookiecutter-django for deployment, I’d
recommend you go to The Eye (somewhere on Reddit and Discord or their
website) to figure out how to name these uploaded files or make some sort
of system to find these files quickly while keeping them private from other
users (by replacing uploaded file names with extremely long names. That’s
how Dropbox does it I believe).

The Eye is like an Archive team. They’re lovely and helpful people,
especially regarding data hoarding which you’re project might entail in...

I try my best to help completely new Django members with great ideas start
their journey or make that giant leap. So if this shit made no sense, don’t
feel frustrated when you could simply clarify some stuff for me. Good luck!

Hi Paras,

Makes it look like you are storing users passwords in cleartext.

If that is correct, then please don't do that. Never, ever. This is 
hopefully just a hobby project, but still it's good to do things 
correctly and learn good habits from the beginning.


Considering your question, you generally can't as HTTP is basically 
stateless, so the "details" view doesn't know about the user object you 
created in your "login" view.


A workaround for this is using session cookies which isn't exactly 
trivial to handle, so thankfully Django provides a way to make that very 
transparent with Django authentication:


https://docs.djangoproject.com/en/2.2/topics/auth/

If you read up on that documentation you would find the answer to your 
question.


It seems a bit like your trying to reinvent something Django already 
provides for you, I could be wrong of course.


Kind regards,

Kasper Laudrup

Have you tried  for the first element, and so forth? Of

Correct Design: one app depending on another app

[Random Body Parts]

So I want to realise a small content management system. I want to make an 
app that allows for the creation of site content. A site content element 
can be a headline, an image, a block of text, etc... Individual content 
elements will be associated with a content container, which is essentially 
a list. A simple blog article would for instance contain a headline and a 
text block. The site content app will also provide its services for other 
apps. For instance there will be an archive for media files (images, music 
in the form of mp3, videos, etc...). So another content container would be 
a music album. It would be made up of a headline, an image (the cover 
artwork) and a list of music files. Now here it gets a little bit more 
complex. The media files will be handled by yet another app. So the content 
container for a music album would incorporate the headline from the site 
content app, but it would also incorporate the media files from the media 
files app, yet it would be displayed by the archive app.
The before mentioned apps don't really have a hierarchical relationship. My 
instinct tells me that all the content container elements (blog article, 
music album, image gallery, etc...) should all be living insidethe site 
content app. However the site content app would then depend on all sorts of 
models from other apps. So is this the correct way to go about it? I want 
the site content app to be pluggable by itself. Now for the more complex 
container elements I need external models. So I'm thinking I would do a 
conditional import, kinda like this:

try:
import jsonexcept ImportError:
import simplejson as json

So then the more complex container models would only be available if the 
needed apps and their models are present.
Any advice on this design approach is very welcome.

Hi,
Do you want to write a python program which read a sqlite3 database and maybe 
do some updates and/or create new records in the database ?

Re: mysql data connectivity problem

[Chaithanya Reddy]

Check whether any database connection u have given in your pc
ex:- if u have already installed any mysql data base in your pc,  then
uninstall that mysql application, restart the pc
After that u can connect to the database of django

Next time post with a pic(what is the error is..??)
So that i can see where the error is getting

Re: Directly Accessing Dictionary Values

[Andrew Stringfield]

First, thank you for the reply Suraj!  I think that I misstated what I was 
really trying to do.  I am trying to access the dictionary values directly 
in the Template and not in the View.  I am trying to remove:

{% for question in unique_key_object %}
   {{ question.filename }}
   {% endfor %}

and just have:
{{ unique_key_object.filename }}
