Any person working with electronics, either for hobby or professionally will have a large assortment of components and parts laying around.
I\u2019d encourage anyone that will keep any kind of inventory of parts to invest some time in creating a system to keep track of the components you have, the location, and the ability to attach information and documents.<\/p>\n\n\n\n

I was already using Partkeepr as described in a previous post<\/a><\/p>\n\n\n\n

I switched over to Inventree<\/a> because Partkeepr has gone stale and is not being maintained anymore.<\/p>\n\n\n\n\n\n

Partkeepr to Inventree data transfer & problems<\/h2>\n\n\n\n

There is a pluging\/script<\/a> to transfer the data from partkeepr to inventree, sadly this one is outdated and not maintained at the time im writing this.<\/p>\n\n\n\n

Luckily Frank Steinberg provided a great python script I was able to use to transfer all my data from Partkeepr to Inventree<\/a>.<\/p>\n\n\n\n

Unfortunatly it did not work on the first try, but with some modification I was able to get it to work for me.<\/p>\n\n\n\n

401 Unauthorized<\/h3>\n\n\n\n

My main issue from the start was the program kept crashing without a clear reason. by adding a printline I saw kept getting a 401 response when requesting data from partkeepr. I had to put in my credentials at the correct locations for the HTTP requests. only putting the credentials into the url at the top of the script did not work for me.<\/p>\n\n\n\n

Here<\/a> you can find more info about the HTTP request package and how to use it.<\/p>\n\n\n\n

Keyerror: 18<\/h3>\n\n\n\n
I kept getting a keyerror because my root catagory did not  have a parent, fixed this by adding a exception catch to ignore the lack of a parrent.<\/p>\n\n\n\n
