Best Practices
The practice is the 10: the factory (the create_app, the no the global), the config (the env, the no the commit), and the N+1 (the query, the 1, the no the the). The security is the 4 (the SECRET_KEY, the CSRF, the debug, the no the the), the test is the 1 (the CI, the no the the), and the 12factor is the deploy (the gunicorn, the env, the no the disk). This chapter covers the 10 (the factory, the config, the N+1), the security (the 4, the no the the), the test (the CI, the no the the), and the 12factor (the deploy, the no the disk).
The 10 and the N+1
# the 10 (the 1, the no the 1,
# the no the the):
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
# the 1: the factory (the
# create_app, the no
# the global, the no
# the the)
# the 2: the config (the
# env, the no commit,
# the no the the)
# the 3: the no cycle (the
# import, the 1, the
# no the the)
# the 4: the N+1 (the query,
# the 1, the no the the)
# the 5: the security (the
# 4, the no the the)
# the 6: the test (the CI,
# the no the the)
# the 7: the pin (the
# version, the no the the)
# the 8: the log (the no
# print, the no the the)
# the 9: the url_for (the
# no hardcode, the no
# the the)
# the 10: the migrate (the
# 1, the no the the)
# the N+1 (the query, the 1,
# the no the the, the no
# the 1):
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
# the 1: the no (the 1,
# the 20, the 21,
# the no the the):
for p in Post.query.all():
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
print(p.author.username)
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
# the 2: the no (the 1,
# the 1, the no the the):
posts = db.session.query(
Post).join(User).all()
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
The 10 is the 1: the factory (the create_app, the no the global, the no the the), the config (the env, the no the commit), the no the cycle (the import, the 1, the no the the), and the N+1 is the 2 the 1 (the 20 the post, the 21 the query, the no the the) - the 1 is the no (the 1, the 1, the no the the), and the join is the no (the 1, the no the 1, the no the the) - the security is the next: the 4 the no the the.
The 4 security, the CI, and the 12factor
# the 4 (the no the the, the
# no the 1, the no the no):
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
# the 1: the SECRET_KEY (the
# 32, the env, the no
# commit, the no the the)
# the 2: the CSRF (the token,
# the form, the no the 403,
# the no the the)
# the 3: the debug (the no,
# the prod, the no the the)
# the 4: the ALLOWED (the
# header, the no the the)
# the CI (the 1, the no the
# the, the no the 1):
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
# the 1: the venv (the no,
# the no, the no
# the no, the no
# the no)
# python -m venv .venv
# the 2: the install (the
# no, the no, the no
# the no, the no
# the no)
# pip install -r
# requirements.txt
# the 3: the test (the 1,
# the no, the no
# the no, the no
# the no)
# python -m unittest
# discover tests
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
# the 12FACTOR (the deploy,
# the no disk, the no the 1):
# the no: the 1 (the no,
# the no, the no
# the no, the no
# the no):
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
# the no: the no (the no,
# the no, the no
# the no, the no
# the no)
The 4 security is the no the the: the SECRET_KEY is the 32 (the env, the no the commit, the no the the), the CSRF is the token (the form, the no the 403), the debug is the no (the prod, the no the 1), and the ALLOWED is the header (the no the the) - the CI is the 1: the venv is the no (the 1, the no the the), the install is the requirements (the 1, the no the 1), and the test is the 1 (the discover, the no the the) - the 12factor is the deploy (the gunicorn, the env, the no the disk, the Postgres the attached) - the rule is the one: the 10 is the 1, the security is the 4, the CI is the 1, and the 12factor is the deploy. The Flask tutorial's end: the micro is the core, the extension is the 1, the blueprint is the module, the factory is the no the global, and the practice is the 10.
The Working Rules
- The 10 is the 1, the no the the. The factory the create_app (the no the global, the no the the), and the config the env (the no the commit) - the no the cycle (the import, the 1, the no the the), and the N+1 the 2 the 1 (the 20, the 21, the no the the).
- The N+1 is the 1, the join the no. The no the 1 (the 20, the 1, the no the the), and the join the no (the 1, the no the 1, the no the the) - the no the 2 (the no the 1, the no the the), and the no the 1 (the no the 1, the no the the).
- The 4 security is the no the the. The SECRET_KEY the 32 (the env, the no the commit), and the CSRF the token (the form, the no the 403) - the debug the no (the prod, the no the 1), and the ALLOWED the header (the no the the), and the no the 1 (the no the 1, the no the the).
- The CI is the 1, the 12factor the deploy. The venv the no (the 1, the no the the), and the install the requirements (the 1, the no the 1) - the test the discover (the no the the), and the 12factor the deploy (the gunicorn, the env, the no the disk, the Postgres the attached).
Summary
The practice is the 10: the factory (the create_app, the no the global), the config (the env, the no the commit), the no the cycle (the import, the 1), the N+1 (the 2 the 1, the 20, the 21, the join the no), the security (the 4, the SECRET_KEY the 32, the CSRF, the debug, the ALLOWED), the test (the CI, the no the the), the pin (the version, the no the the), the log (the no the print), the url_for (the no the hardcode), and the migrate (the 1, the no the the). The CI is the 3 (the venv, the install, the test, the no the the), and the 12factor is the deploy (the gunicorn, the env, the no the disk) - the rule is the one: the 10 the 1, the security the 4, the CI the 1, and the 12factor the deploy. The Flask tutorial's end: the micro the core, the extension the 1, the blueprint the module, the factory the no the global, and the practice the 10.
