+
+This module provides a **generic**, reusable mechanism to **save** and
+**apply** named templates that autocomplete any Odoo wizard/form using a
+**JSON payload** stored in a template record.
+
+It is designed to be **framework-like**: other modules can inherit the
+mixin and add a few buttons in XML.
+
+--------------
+
+What you get
+------------
+
+1) Template model
+~~~~~~~~~~~~~~~~~
+
+``data.autocomplete.template``
+
+Each template stores:
+
+-  ``name``: template name
+-  ``model_id``: the target Odoo model (``ir.model``) the template
+   applies to
+-  ``company_id``: company scoping (global or per company)
+-  ``user_id``: optional owner (personal templates)
+-  ``values_json``: a JSON dictionary holding serialized default values
+
+2) Mixin
+~~~~~~~~
+
+``data.template.mixin``
+
+Add it to any wizard/model to get:
+
+-  ``template_id`` field (select a template)
+-  actions (for buttons):
+
+   -  ``action_open_create_template_wizard()``
+   -  ``action_update_current_template()``
+   -  ``action_apply_template(overwrite=True)``
+
+3) Create Template Wizard
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``data.wizard.template.create``
+
+This popup asks for a **name** (and personal/global scope) and creates
+the template using the current wizard/model values.
+
+JSON serialization
+~~~~~~~~~~~~~~~~~~
+
+The mixin serializes current values into a JSON-safe dict:
+
+-  ``many2one`` -> the record ``id`` (or ``false``)
+-  ``many2many`` -> a list of record ids
+-  basic fields
+   (char/int/float/bool/date/datetime/selection/text/monetary) -> stored
+   as-is
+-  ``one2many`` is ignored
+-  computed fields without inverse and readonly fields are ignored (by
+   default)
+
+Applying templates safely with onchanges
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Applying a template uses a **phased write**:
+
+1. **Drivers**: fields returned by ``_template_driver_fields()`` are
+   written first
+2. **Rest**: everything else (excluding protected fields)
+3. **Protected**: fields returned by ``_template_protected_fields()``
+   are written last
+
+This solves common wizard issues where changing a driver field triggers
+an onchange that clears other fields (e.g. changing ``plan_id`` clears
+``account_ids``).
+
+While applying, ``apply_template=True`` is present in the context so you
+can skip destructive onchanges in your own code.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Usage
+=====
+
+1) Inherit the mixin in Python
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code:: python
+
+   from odoo import models, api
+
+   class MyWizard(models.TransientModel):
+       _inherit = ["my.wizard.model", "data.template.mixin"]
+
+       # Optional: define drivers/protected fields to survive onchanges
+       def _template_driver_fields(self):
+           return {"plan_id"}
+
+       def _template_protected_fields(self):
+           return {"account_ids", "show_months"}
+
+       @api.onchange("plan_id")
+       def _onchange_plan_id(self):
+           # Skip destructive behavior when applying templates
+           if self.env.context.get("apply_template"):
+               return
+           return super()._onchange_plan_id()
+
+..
+
+   Note: This module only provides the base.
+
+2) Add UI in XML (template selector + buttons)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Insert this into your wizard form view (adapt ``inherit_id`` and the
+``xpath``):
+
+.. code:: xml
+
+   <separator string="Templates"/>
+   <group col="4">
+       <field name="template_id" options="{'no_create': True}"/>
+
+       <button name="action_apply_template"
+               type="object"
+               string="Apply"
+               class="btn btn-secondary"
+               icon="fa-check"
+               invisible="not template_id"/>
+
+       <button name="action_open_create_template_wizard"
+               type="object"
+               string="Save as template"
+               class="btn btn-secondary"
+               icon="fa-save"/>
+
+       <button name="action_update_current_template"
+               type="object"
+               string="Update template"
+               class="btn btn-secondary"
+               icon="fa-refresh"
+               invisible="not template_id"/>
+   </group>
+
+3) Filtering templates further (optional)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the same wizard model can represent different "types" of reports
+(e.g. different ``report_id``), you can further restrict the templates
+shown by overriding:
+
+.. code:: python
+
+   def _template_domain_extra(self):
+       return [("some_field", "=", self.some_field.id)]
+
+--------------
+
+Notes / Tips
+~~~~~~~~~~~~
+
+-  If you want templates shared across companies, allow
+   ``company_id = False`` templates (already supported by the domain).
+-  If you want only personal templates, set ``user_id`` on every
+   template and adjust the domain.
+-  If some fields should never be stored (tokens, volatile flags, etc.),
+   override ``_template_skip_fields()``.
+
+--------------
