Our Compiler.py python script converts the traits in Roster.csv into a JSON file for each row.
While this logic can be used for a number of applications, our example creates JSONs for an NFT collection called ParkPics. Find the full repo for ParkPics here, which covers metadata pinning/upload, smart contracts, deployment, verification, and OpenSea import.
First, adjust the image pin to reflect your images' CAR file. Learn more about CARs in our ERC 1155 repo.
archive = "ipfs://bafybeiatmiig6ylhha5p7o7bxvqutfitv6k2n5ghche4r22tgkmoz6gu5u/"
Next, update the Compiler.py variables for your metadata fields and number of rows. For debugging purposes, we use descriptive labels for each variable.
filename = row[0]
name = row[1]
park = row[2]
type = row[3]
feature = row[4]
Finally, update NFTjson = ... for the desired fields in your JSONs. Learn more from the NFT School about token metadata standards.
Run the Compiler.py script in your IDE/CLI of choice. If you're new to Python scripts, check out this Python tutorial from VS Code.
Before uploading your JSONs, we recommend opening a few in VS Code (or a similar IDE), right clicking anywhere in the JSON, and selecting Format Document. Then, the IDE should flag any formatting errors that you'd need to fix in your Python script.
