海外TECH	DEV Community	Doctoring your application configuration	https://dev.to/dev_dull/doctoring-your-application-configuration-31f	Doctoring your application configuration Opinion Code for configuration handling is uglyIf you ve ever written a statement that looks something like my setting config value if config value else some default and hated it then I expect we can agree that handling application configuration is a miserable thing to code for Its boring to write ugly to read and annoying to ensure that all user configuration options have sane default values The argparse library can go a long way to making things better but if you need to set dozens of options or if your application supports plugins with configuration requirements unknown to the main program it becomes harder to simply add argument our way back to sanity In these cases it makes more sense to opt for a configuration file Also it would be nice if our application code didn t care about the configuration file at all where we had a single source of truth to count on being correct Getting ClassyWhen I ve hit the point in my development process where I have the basic functionality working and I ve settled on the basics of how the program will flow I like to create a new python file constfig py and define the class C where the C stands for both constants and config and that s good enough for me Both config and constants start with C By convention I lead the with an underscore to signal to the other developers on the project that the class isn t intended to be implemented directly and at the end of the file I create an instance of C called C which can be imported and will contain all the information needed by the application For example let s implement a simple dice rolling API endpoint using Flask which returns a JSON formatted string For this type of application we would want to be able to easily configure the IP address and port that the service listens on so let s define our C class establish the variable names pre populate the variables with some reasonable default values and then create an instance of our class named C which the user is meant to import from our file class C object def init self self LISTEN IP self LISTEN PORT C C We also have certain values which will never change at runtime but if our specification changes later we don t want to have to hunt down all instances of that value in our code so let s also add our constant values class C object def init self Constant values self JSON RESPONSE KEYWORD DROLL d roll User configurable values self LISTEN IP self LISTEN PORT C C Now that we have our constant values and our configurable variables with sane defaults let s import C the instance of C into our main Flask application from constfig import C Our constants config constfigfrom random import randintfrom flask import Flask jsonifyapp Flask name app route rolld def roll d value C JSON RESPONSE KEYWORD DROLL randint return jsonify value if name main app run host C LISTEN IP port C LISTEN PORT We can now give it a quick run user host python roll py Serving Flask app roll lazy loading Environment production WARNING This is a development server Do not use it in a production deployment Use a production WSGI server instead Debug mode offINFO werkzeug Running on Press CTRL C to quit and test to make sure all looks good so far user host curl s localhost rolld python m json tool d value ‍️Operate on your selfNow that we have our application and our C class we re ready for it to poke at its own guts Let s add the function load config which will open up our configuration file config yaml and then use the setattr function to update our own values at startup when Python runs from constfig import C Python s ability to alter its own state is knows as reflection or reflective programming import yamlimport loggingclass C object def init self Constant values and a gotcha self JSON RESPONSE KEYWORD DROLL d roll User configurable values self LISTEN IP self LISTEN PORT Load user config override defaults above self load config def load config self try config file open config yaml r config string config file read config file close configuration yaml load config string Loader yaml SafeLoader Don t handle badly formatted YAML Let the parser inform the user of the error if isinstance configuration dict for variable name value in configuration items setattr self variable name value else raise yaml scanner ScannerError f The file config yaml should be structured as type dict but got type type configuration except FileNotFoundError logging warning Configuration file config yaml is missing Using default values C C We can now create our config yaml file containing key value pairs where the key matches the name of our configuration itemsLISTEN IP LISTEN PORT Let s fire up the service again user host python roll py Serving Flask app roll lazy loading Environment production WARNING This is a development server Do not use it in a production deployment Use a production WSGI server instead Debug mode off Running on Press CTRL C to quit and this time we see that the default values have been overridden by those in the configuration file Specifically we re now listening on the loopback IP and that our port number has changed as expected Gotta catch that gotcha The problem with this method is that we open ourselves up to having the configuration file change values that should not be changed For example if we set JSON RESPONSE KEYWORD DROLL this is bad in config yaml then make a request to our endpoint we see that we ve indirectly altered our application s response user host curl s rolld python m json tool this is bad While the fix here isn t hard this bad behavior underscores the importance of the order in which we set out values Let s move our constant values to where they are being set after the values in our configuration file by adding a finally clause to our try except block on load config and call our new method set constants import yamlimport loggingclass C object def init self User configurable values self LISTEN IP self LISTEN PORT Load user config override defaults above self load config def set constants self Constant values self JSON RESPONSE KEYWORD DROLL d value def load config self try config file open config yaml r config string config file read config file close configuration yaml load config string Loader yaml SafeLoader Don t handle badly formatted YAML Let the parser inform the user of the error if isinstance configuration dict for variable name value in configuration items setattr self variable name value else raise yaml scanner ScannerError f The file config yaml should be structured as type dict but got type type configuration except FileNotFoundError logging warning Configuration file config yaml is missing Using default values finally self set constants C C then launch again using our bad which tries to set JSON RESPONSE KEYWORD DROLL configuration file user host python roll py Serving Flask app roll lazy loading Environment production WARNING This is a development server Do not use it in a production deployment Use a production WSGI server instead Debug mode off Running on Press CTRL C to quit and of course test the result user host curl s rolld python m json tool d value Tada A single source of truth for your Python application You hate this but I need validationYes I hear you bemoan I ve got a children s song about cookies stuck in my head I m half way through a pack of Oreos and this seems like an abstraction that makes it harder to see how the configuration is loaded Yeah this solution is probably not for everyone but I ve hidden the superpower of this method behind a mild mannered alter ego The real power is automatic validation of your configuration simply by importing C To do this let s define the function validate config write some basic assertions to validate the configuration and then call the function after we have successfully loaded the yaml file and set the constant values in our class import yamlimport loggingclass C object def init self Default values for user configurable items self LISTEN IP self LISTEN PORT Load user config override defaults above self load config def set constants self Constant values self JSON RESPONSE KEYWORD DROLL d value def load config self try config file open config yaml r config string config file read config file close configuration yaml load config string Loader yaml SafeLoader Don t handle badly formatted YAML Let the parser inform the user of the error if isinstance configuration dict for variable name value in configuration items setattr self variable name value else raise yaml scanner ScannerError f The file config yaml should be structured as type dict but got type type configuration except FileNotFoundError logging warning Configuration file config yaml is missing Using default values finally self set constants self validate config Validate our config file def validate config self Validate LISTEN IP assert isinstance self LISTEN IP str LISTEN IP is not a string value assert len self LISTEN IP split LISTEN IP has an unexpected number of octets assert all ip isnumeric for ip in self LISTEN IP split LISTEN IP is not a valid IP address assert all lt int ip lt for ip in self LISTEN IP split LISTEN IP is not a valid IP address Validate LISTEN PORT if isinstance self LISTEN PORT str assert self LISTEN PORT isnumeric LISTEN PORT must be a whole number self LISTEN PORT int C LISTEN PORT assert lt self LISTEN PORT lt LISTEN PORT is outside expected range C C and just as an example let s put a deliberate typo in our configuration file LISTEN IP x My fingers are fat LISTEN PORT Now have a couple of opportunities to validate our configuration For example at runtime user host python roll py Traceback most recent call last File roll py line in lt module gt from constfig import C Our constants config constfig File Users adrong PycharmProjects constfig constfig py line in lt module gt validate config File Users adrong PycharmProjects constfig constfig py line in validate config assert all a isnumeric for a in C LISTEN IP split LISTEN IP is not a valid IP address AssertionError LISTEN IP is not a valid IP address or run constfig py directly to validate your configuration in your test or deployment pipelines user host python constfig py Traceback most recent call last File constfig py line in lt module gt validate config File constfig py line in validate config assert all a isnumeric for a in C LISTEN IP split LISTEN IP is not a valid IP address AssertionError LISTEN IP is not a valid IP address Small but mightyThis is a relatively small amount of code that with some tweaks can source configuration from a database from environment variables from command line arguments and can have validation code that can reconcile configuration from any combination of those sources This pattern for handling configuration has enabled me to quickly create configuration handling in a standardized way across multiple tools that members of other teams have found approachable and easy to manage	2022-01-01 02:15:00
