New to django-cms, django-filer, have secure downloads working, but would like to allow users with minimal permissions (that is, just logged in, not django staff or admin access) to view files, how or where should I look to edit these permissions levels?

let users download files from my aws bucket using django
I am working on a document sharing site for students that lets them upload and download files directly to/from from the site. Right now I have the site set up to where they can upload the files (which sends those files to an AWS bucket), however I cannot get it to where they can download the files. One of the paths that I am given is ^mysite.s3.amazonaws.com/media/(?P.*)$. I am trying to use this path to let users download the files however I just get sent to an error 404 page. Is there an IAM policy or special path that lets users download files from my bucket? I am assuming there is something, I just haven't found anything useful on the web. Thank you in advance for any light you can shine on my question! My Current IAM Policy is this: { "Statement": [ { "Effect": "Allow", "Action": [ "s3:ListBucket", "s3:GetBucketLocation", "s3:ListBucketMultipartUploads", "s3:ListBucketVersions" ], "Resource": "arn:aws:s3:::<your_bucket_name>" }, { "Effect": "Allow", "Action": [ "s3:*Object*", "s3:ListMultipartUploadParts", "s3:AbortMultipartUpload" ], "Resource": "arn:aws:s3:::<your_bucket_name>/*" } ] } My Current AWS Settings are this: AWS_ACCESS_KEY_ID = "key_ID" AWS_SECRET_ACCESS_KEY = "key" AWS_FILE_EXPIRE = 200 AWS_PRELOAD_METADATA = True AWS_QUERYSTRING_AUTH = True DEFAULT_FILE_STORAGE = 'mysite.utils.MediaRootS3BotoStorage' STATICFILES_STORAGE = 'mysite.utils.StaticRootS3BotoStorage' AWS_STORAGE_BUCKET_NAME = 'mysite' … -
django-OperationalError at /register/ no such table: auth_user
I have tried many way to solve this, but none of them work. My question is when I tried to register a user, it shows an error no such table: auth_user .

String processing issues with special characters ('ascii' codec can't decode byte)
I run a Django forum (with postgresql backend) where users post regarding various topics. I employ the excellent fuzzywuzzy python library to check every user's post against the same user's previous post. If the post is a fuzzy match (e.g. 85% similar), I encourage the user to differentiate his/her newest post further. To ensure this works, I've been storing each user's previous posts in the profiles on the postgresql DB. To validate whether the latest user comment, I thus do: score = fuzz.ratio(latest_comment,submitter.userprofile.previous_comment) if score > 85: #show the user a friendly prompt Lately, I started saving all previous comments in redis, instead of making expensive DB calls. The code simply became: score = fuzz.ratio(latest_comment, get_prev_comment(user_id)) if score > 85: #show the user a friendly prompt Where get_prev_comment() is a redis function that extracts the user's previous comment. My problem is that this fails when strings contain special characters such as this:۞. Exact error being: 'ascii' codec can't decode byte 0xdb in position 0: ordinal not in range(128). It worked perfectly with Django's postgresql backend (where I was using Django's CharField() attribute to save it in the model). Can anyone point out what's changed and how I can fix this? … -
Either redirect or show a message (Django)
Writing a reusable Django component: Calling certain function of my component should either redirect to PayPal site (if the trial period is zero) or show the message to the user that he has registered and entered into a trial period. The problem is that because the component is reusable, I don't know in advance how the message should be shown: It may be redirect to a page which shows the message or it may be a JavaScript based popup window, etc. How to make a reusable Django method which can be customized in these ways? -
How do a for loop to this function in Django?

What's the best way to load stored procedures into the Django unit test database?
I've got some Postgres stored procedures that my selenium tests will depend on.

Is using SQLalchemy for a core python package and Django ORM for users a good idea?
I have a core python package used for data analysis. I also have a web-framework which provides a UI to this package as well as an API for accessing data. Currently, I'm using the django ORM for creating users etc. and I am executing manual SQL to return data from my core python package database. I'm looking to use an ORM for the core python package as well, and I am split between using Django ORM (which seems to be less flexible overall and gave me some problems when trying to use outside of django) and SQL alchemy (which would require having two ORMs, one for the core package to handle core data and one for the django site to manage users etc.) Before diving in to either too deeply, I'm not sure which path makes more sense. -
