### TODO: get all this inside a docker container and use compose to do the whole set (pg, flask, ?)
	see this for postgresal: 
		https://hub.docker.com/_/postgres (has several env vars that should work out)
	and probably this:
		https://docs.docker.com/compose/gettingstarted/ (for flask and maybe redis)


# flask -> python web server
# sqlalchemy -> provides db-agnostic python objects of db content (and more)
# flask-sqlachemy combines/wraps this to provide a db.* set of objects based on the 'app' that flask creates
# marshmallow-sqlachemy provides a way to create a 'schema' of your class, then serialize an object to it 
# flask-wtf -> 'what the form' allows form consistency/validation based on defining attributes in a class for each form
# flask-bootstrap -> allows me to format that wtf form with boostrap markup - yet to test if it also means I don't need to include it exlicitly in head, etc.

# install needed binaries (maybe I could have done this instead of pip below too -- when I docker this shit, sort it out?)
sudo apt install python3-pip python3-psycopg2 libpq-dev

### LEARN: supposedly could use virtualenv instead of pip3 install --user? OR even apt to install direct?
# --user sticks python libs in ~/.local/[bin|lib|share]
pip3 install --user flask sqlalchemy flask-sqlalchemy flask-marshmallow SQLAlchemy-serializer flask-wtf flask-bootstrap marshmallow-sqlalchemy


# run the web server by:
python3 main.py


### TODO: 
	- need to save a book
		- still missing publisher, notes, blurb.  
		- not sure about series/loan/subbook, etc.
	- need to create all classes (green + button)
	- need to delete all classes (and watch for referential integrity)
	- need to add 1 author to book, book to sub_book, series
	- need to delete 1 author from book
	- need to delete 1 book from sub_book, series, loan
	- need to create/add books to loan
	- add stats page
	- show books on shelf list
	- show books to buy view / printable
	- with ORM: do I to lazy load all books (ajax the 2nd->last pages in, or not use ORM, and do a quick db.execute()....)


### MAYBE:
	when moving a book in a series (which is part of 2 series), do we pop-up
	offer to move parent/child series orders as well to match (think Thomas Covenant)
	

### WARNING WARNING, edit book has broken publisher setting on GET of /book/<id>, DONT SAVE, until FIX as per below ###
	need to get publisher to be a single 1-to-many Foreign key, not linkage many-to-many table
	think I recall add new field to book (new_pub_id) as Foreign key
	use ORM to copy into new_pub_id, from publisher[0].id
	rename publisher to old_pub_field
	rename new_pub_id to publisher
	TEST
	delete book_publisher_link table
	delete column old_pub_field 
	profit
