If you’re looking for assistance here, we’re going to need a _lot_ more detail about what’s going on. At a minimum I think we’d need a description of your environment, how you’ve tried to deploy it, the relevant configuration files, and the exact error message(s) you’re receiving in the log(s). ---

I deployed a django app on apache 2 with mod wsgi. All the website works, less a function wich use some libraries that are installed in the virtual environment. I´m using a raspberry py with raspberrian Database its working like a charm. Apache file: ```auto ServerAdmin webmaster@localhost DocumentRoot /var/www #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /static /var/www/nfcReader/static Require all granted Require all granted WSGIDaemonProcess inov python-path=/var/www/nfcReader python-home=/home/inov/env WSGIProcessGroup inov WSGIScriptAlias / /var/www/nfcReader/nfcReader/wsgi.py ``` By the way, where does django store actual wsgi errors? ---

That’s a start. We’re still going to need more specifics on the errors being received though. > [@goncaloLopesMarques](#): > > By the way, where does django store actual wsgi errors? The mod\_wsgi-based errors are going to be found in the Apache logs - usually in `/var/log/apache2`. (All configurable based upon your Apache settings.) The Django-related errors are going to be wherever your Django logger is directing them. ---

> [@goncaloLopesMarques](#): > > `[Errno 13] Permission denied: '/dev/spidev0.0'` That’s pretty straight forward. The `www-data` uid most-likely doesn’t have direct access to that device. But first, my biggest concern would be handling the possibility of concurrent access between process instances of Apache. When I’ve had to expose hardware interfaces to the web on a Pi, I create an intermediate layer “shim” that runs as a persistent task. I then use Redis as the communication link between Django and that shim. The shim is a Python program running as root, giving it direct access to the hardware. The flow of the request/response ends up being: - Browser issues a request - Web server receives a request - Django view executes - Posts a message on redis, including the name of a response queue - Does a blocking read on the response queue - Builds the response from the data returned - Return the response to the browser. Meanwhile, the shim consists of: - While True: - Do a blocking read on the message queue - When a message is received, set/retrieve the data from the hardware - Return a response to the response queue. The latency involved in this is negligible compared to the amount of time that Django is going to spend preparing the response to be returned to the browser. I have also done this using Channels, where one or more browsers are monitoring a Pi, and when data is updated, it’s sent asynchronously to all connected browsers. ---

Humm its a nice question. But my apache will have only running one project, so i have sure that one process will acess the hardware. ---

> [@goncaloLopesMarques](#): > > But my apache will have only running one project, so i have sure that one process will acess the hardware. That by itself is not an accurate statement. The standard Apache configuration starts multiple worker processes. Also, have you ever (intentionally or otherwise) opened up two browser tabs to the same page? Same situation. You **need** to assume multiple access. ---

i will try to test that. But this its a admin tool. So one person will use this in a very controled whay(by me =p) Later i will look at your use case but now i need to send the first version of the project till friday. I add the www-data to the spi group but no luck, this time the error its: ```auto No access to /dev/mem. Try running as root! ```
