Hi,

To retrieve a complete model schema from Odoo via XML-RPC, you can use the ir.model and ir.model.fields models. First, authenticate with Odoo using XML-RPC and set up the models proxy. You can then fetch a list of all models with search_read on ir.model to get both the technical and human-readable names.

For each model, you can query ir.model.fields to get the fields’ details, including name, label, type (ttype), relation (for relational fields), and required or readonly status. This allows you to generate a full schema for a model, showing all fields and their properties.

To document all models, you can loop through the list of models and fetch their fields in the same way. System models can be filtered out if not needed, and the schema can be exported to CSV or Markdown for easy reference. This approach provides a comprehensive view of all models and fields in the Odoo database.

1. Connect to Odoo via XML-RPC

import xmlrpc.client

url = "https://your-odoo.com"

db = "your_db"

username = "your_user"

password = "your_password"

# Authenticate

common = xmlrpc.client.ServerProxy(f"{url}/xmlrpc/2/common")

uid = common.authenticate(db, username, password, {})

# Set up models proxy

models = xmlrpc.client.ServerProxy(f"{url}/xmlrpc/2/object")

2. Get a list of all models

models_list = models.execute_kw(db, uid, password,

    'ir.model', 'search_read',

    [[]],  # empty domain = all models

    {'fields': ['model', 'name']}

)

for m in models_list:

    print(m['model'], m['name'])

3. Retrieve all fields for a model

model_name = 'res.partner'  # example model

fields_info = models.execute_kw(db, uid, password,

    'ir.model.fields', 'search_read',

    [[('model', '=', model_name)]],

    {'fields': ['name', 'field_description', 'ttype', 'relation', 'required', 'readonly']}

)

for f in fields_info:

    print(f)

-Some system models are technical and may not be needed for documentation (ir.actions.*, ir.model, etc.). You can filter them out.

-ttype indicates the type (char, many2one, one2many, float, etc.).

-relation is the related model for relational fields.

Hope it helps
