First post to this group; I hope it's appropriate and has the necessary info.
My goal is to set ["SESSION_FILE_DIR"] = 'C:/some/path' to a path where files
uploaded via my app can be saved. Now my app is very large and so it is
factored in a large collection of blueprints and I want the same settings to be
applied globally across the application. That is, ["SESSION_FILE_DIR"] =
'C:/some/path' would be the session path for any aspect of the program.
I am currently unable to make the desired path available in my blueprints; it
is only available for routes contained within the main app. Below, for purposes
of debugging, I've created a small example that prints the path to the screen.
As an example, if you create this below and head over to the route
.../print_dir the path is visible and I can actually save files to that
location. However, if I head over to the registered blueprint path, .../new, I
get the error the server is not defined.
What steps do I need to take so that the session path I want to save to is
available in my blueprints?
Thank you
