web (data-resources) migration

Posted on Edited on

Recently, I was moving a couple of web portals (backed by Django) to another server. Because all web portals was developped to be transferable, many unexpected problems were encountered.

  1. Soft links

    1
    cp --remove-destination ./ ./

  2. mixed absolut and relative file path

  3. Implicit required R packages

    Instead of loading packages in the header, some functions were loaded using “::”

  4. Function signature changed

    1
    2
    3
    readr::read_rds(path=) #deprecated

    read::read_rds(file=)  #current signature

  5. admin keyword blocked

    My organization blocked any requests containing admin keyword (403 forbidden). Thus, some static files, such as sb-admin.js, could be loaded. These have to be replaced or renamed.
