Package: aio-odoorpc
aio-odoorpc: an async Odoo RPC clientThis package builds upon the lower-levelaio-odoorpc-baseadding a AsyncOdooRPC/OdooRPC class as a thin layer that makes for a friendlier interface.AsyncOdooRPC is asynchronous code, OdooRPC is synchronous.This package does not intend to implement all the functionality of other odoo rpc modules
like ERPpeek and odoorpc. This is meant to be simpler but equally easy to work with without
trying to be too smart. One of the motivations of this package was to have an alternative to odoorpc
which started getting in my way. For instance, just instantiating a new object in odoorpc may result
in a roundtrip to the remote Odoo server. These unnecessary RPC calls quickly add up and it becomes
too difficult to develop fast software. Also, odoorpc offers no asynchronous interface which
is a huge lost opportunity for code that spends a lot of time waiting on blocking network calls.Why use this instead of aio-odoorpc-baseWith this interface you can instantiate an object once and then make simpler invocations to remote
methods likelogin, read, search, search_read and search_count. With aio-odoorpc-base, you get only
the lower levelexecute_kwcall and must pass a long list of parameters on every invocation.Also, aio-odoorpc let's you simulate behavior of odoorpc by instantiating the AsyncOdooRPC class with
adefault_model_nameso then all method calls do not need to pass amodel_name. In this way, you can
easily replace the usage of odoorpc with this object (I know because I migrated a lot of code away
from odoorpc). Of course, if you are migrating from odoorpc you should take the opportunity to
migrate to async code as well.LimitationsRight now there are built-in helper functions only for getting info out (read, search, search_read,
search_count), nothing to help creating new records or updating field values. Those are coming soon.Things to know about this module:Asyncio is a python3 thing, so no python2 support;Type hints are used everywhere;This package uses jsonrpc only (no xmlrpc);You need to manage the http client yourself. Code is tested with requests (sync),
httpx (sync and async) and aiohttp (async). See 'Usage' for examples;I am willing to take patches and to add other contributors to this project. Feel free to get in touch,
the github page is the best place to interact with the project and the project's author;The synchronous version of the code is generated automatically from the asynchronous code, so at
least for now the effort to maintain both is minimal. Both versions are unit tested.Things to know about Odoo's API:Thelogin()call is really only a lookup of the uid (an int) of the user given a
database, username and password. If you are using this RPC client over and over in your code,
maybe even calling from a stateless cloud service, you should consider finding out the user id (uid)
of the user and pass the uid instead of the username to the constructor of AsyncOdooRPC. This way,
you do not need to call thelogin()method after instantiating the class, saving a RPC call;The uid mentioned above is not a session-like id. It is really only the database id of the user
and it never expires. There is really no 'login' step required to access the Odoo RPC API if you
know the uid from the beginning;You will need the url of your Odoo's jsonrpc endpoint. Usually, you will just need to add 'jsonrpc' to
your odoo url. Example: Odoo web GUI on 'https://acme.odoo.com', JSONRPC will be on 'https://acme.odoo.com/jsonrpc'.
However, you may alternatively use one of the three helper methods offered by aio-odoorpc-base.helpers
to build the correct url:defbuild_odoo_base_url(*,host:str,port:Optional[int]=None,ssl:bool=True,base_url:str='')->str:...defbuild_odoo_jsonrpc_endpoint_url(*,host:str,port:Optional[int]=None,ssl:bool=True,base_url:str='',custom_odoo_jsonrpc_suffix:Optional[str]=None)->str:...defodoo_base_url2jsonrpc_endpoint(odoo_base_url:str='',custom_odoo_jsonrpc_suffix:Optional[str]=None)->str:...To import them usefrom aio_odoorpc_base.helpers import build_odoo_base_url, build_odoo_jsonrpc_endpoint_url, odoo_base_url2jsonrpc_endpointExamples:build_odoo_base_url(host='acme.odoo.com',base_url='testing')>>>>https://acme.odoo.com/testingbuild_odoo_jsonrpc_endpoint_url(host='acme.odoo.com',base_url='testing')>>>>https://acme.odoo.com/testing/jsonrpcodoo_base_url2jsonrpc_endpoint('https://acme.odoo.com/testing')>>>>https://acme.odoo.com/testing/jsonrpcUsageNote: check the tests folder for more examplesI will omit the event_loop logic I assume that if you want an async module you already have
that sorted out yourself or through a framework like FastAPI.
All examples below could also be called using the synchronous OdooRPC object, but without the
'await' syntax.fromaio_odoorpcimportAsyncOdooRPCimporthttpx# If the http_client you are using does not support a 'base_url' parameter like# httpx does, you will need to pass the 'url_jsonrpc_endpoint' parameter when# instantiating the AsyncOdooRPC object.asyncwithhttpx.AsyncClient(base_url='https://acme.odoo.com/jsonrpc')assession:odoo=AsyncOdooRPC(database='acme_db',username_or_uid='demo',password='demo',http_client=session)awaitodoo.login()try:# A default model name has not been set a instantiation time so we should# pass the model_name on every invocation.

The name of the odoo databaseusername_or_id: string or int, required. If you pass username (a string), an invocation of the
method 'login()' will be required to fetch the uid (an int). The uid is what is really needed,
if you know both username and uid pass the uid and avoid a login() call which costs a roundtrip
to the Odoo server;password: string, required. The user's password. Unfortunately, Odoo's jsonrpc API requires the
password to be sent on every call. There is no session or token mechanism available as an alternative
authentication method.http_client: an http client, optional. If an http client is not set, you will need to pass the
http_client parameter on every method invocation (when available). Some http clients (e.g. httpx)
let you create a session setting the appropriate url as inasync with httpx.AsyncClient(base_url='https://acme.odoo.com/jsonrpc as sessionif you do that on a supporting client, you do not need to pass url, it is already set on the
http_client. Otherwise, you will need to passurl_jsonrpc_endpointto the constructor.url_jsonrpc_endpoint: string, optional. The url for your Odoo's server jsonrpc endpoint. You should
always pass it unless your http_client already knows to which url it should point to.
You may use aio-odoorpc-base helper methodsbuild_odoo_base_url, build_odoo_jsonrpc_endpoint_url, odoo_base_url2jsonrpc_endpointthat were described earlier in this README to build this url.
In short, the jsonrpc endpoint is your odoo instance's base url with a 'jsonrpc' suffix:https://acme.odoo.com/jsonrpcdefault_model_name: str, optional. This parameter sets the default model_name for all method
invocations that take an optional method_name parameter. If you set 'model_name' on a method
invocation it will override this default and follow your order. When you have an instance of
AsyncOdooRPC/OdooRPC you can create a copy with a different default method_name calling the
method new_for_model('sale.order.line'). You can use this style to mimic odoorpc's way where
you can call search, read, search_read on a specific model.odoo=AsyncOdooRPC(...)sale_order=odoo.new_for_model('sale.order')sale_order_line=odoo.new_for_model('sale.order.line')partner=sale_order.new_for_model('partner')Just remember that new_for_method is nothing special, it only sets a default model name on a
copy of an instance. Making copies of copies is perfectly ok.DependenciesThis package depends onaio-odoorpc-basewhich has no dependency itself.
