DIY Camera Clip For Mirrorless & Film Cameras

Summery: An oversized pen-clip like attachment can be made with simple tools to attach mid-sized cameras to a pant pocket, removing the need for camera straps and other complicated hardware alternatives.

After 6 years of total burnout from a career in commercial photography, an interest in taking photos has started to grow on me, this time in the form of film photography and film development. I've got a long term goal of taking photos of my children, developing the film, printing the photos in a darkroom, and then hanging them in hand built frames. (Full-stack photography?) To that end, I've started to take a camera with me when I take my children out to places.

My goal

I'd like to be able to grab a camera and keep it with me while playing in a park, walking around a musium, and doing all the activities that dads do with their kids. It must not get in the way, must be comfortable, and be quick to access and put away. Modifying the camera is not a

Generic Bulk Updating

After writing up a number of CLI scripts to update various model values in a Django app, it occurred to me that a generic script could be written that would work for all of my purposes. What follows is a simple catch-all script that can be used in any django app as is!

The script works by taking in the following values:

• Model name
• Field name
• New value type
• New value

Auto Expiring Django Users

When there is a need to give a user temporary access in Django, typically, you will need to enable their user and then expire their user manually. This creates an issue as it relies on remembering to disable the user. One way to deal with this is to save the expiration time somewhere and have a script running that will expire users, however this creates another weak point in the app and a critical scheduled job to make sure is always running.

My Solution

In an app where security was critical and where such a scheduled script would have been subject to audits, I found this method to work perfectly:

Rather than use a boolean to indicate active status, use datetimes for active start and end times and let Django figure out if the user is active based on the current time.
