What Is a Wizard in Odoo 18?
Firstly, a wizard in Odoo 18 is a special kind of transient model that is used to collect user input and perform activities on the fly. Furthermore, wizards enhance the user experience by displaying forms in pop-up dialogs or temporary windows. In addition, they provide a focused interface for executing complicated tasks in a simple, guided manner. Moreover, the Odoo 18 wizard function is integral when you need to perform operations that do not require a persistent database record. Consequently, many business applications use these ephemeral forms to streamline user interaction. Also, wizards use a set of views designed specifically for short-term tasks.
Key Features of Odoo 18 Wizards
Transient Models: The Backbone of Wizards
Firstly, wizards in Odoo are built upon transient models that do not store data permanently. Next, these models use special configurations to ensure that the data is automatically cleared after use. Moreover, developers appreciate their lightweight nature because they are easy to deploy in scenarios that require temporary data handling.
User Interaction and Form Views
Secondly, wizards offer well-designed form views that display fields for user input. In addition, they are configured to pop up as modal dialogs, which encourages clear and concise user interaction. Furthermore, these forms are customizable, allowing you to add buttons, messages, and even multiple-step forms.
Step-by-Step Guide to Building a Wizard in Odoo 18
In this section Odoo 18 Wizard Basics, we provide a practical, step-by-step guide to help you build your own Odoo 18 wizards. Every step is explained clearly using active voice and transition words so that you can follow along with ease.
Setting Up Your Odoo Environment
Firstly, you must set up your development environment by installing Odoo 18 and configuring your database. Next, ensure that you have access to the Odoo source code. In addition, create a new custom module where your wizard will reside. Consequently, you must structure your module’s directories as follows:
my_wizard_module/
├── __init__.py
├── __manifest__.py
├── models/
│ └── __init__.py
│ └── my_wizard.py
└── views/
└── my_wizard_view.xmlFurthermore, you will need to declare your module in the manifest file. Here is a sample __manifest__.py file:
{
'name': "My Wizard Module",
'version': '1.0',
'depends': ['base'],
'author': "Your Name",
'category': 'Tools',
'summary': "Odoo 18 Wizard Basics Tutorial",
'description': """A complete guide on building wizards in Odoo 18.""",
'data': [
'views/my_wizard_view.xml',
],
'installable': True,
'application': False,
}This file clearly defines the module’s dependencies and includes the view definition that the wizard will use. Finally, install your module via the Odoo interface.
Creating the Wizard Model
Next, you need to define the transient model for your wizard. In addition, you should use active voice in your code comments to ensure clarity. Below is an example of a Python file that creates a basic wizard with user input and a computed result:
from odoo import api, fields, models
class MyWizard(models.TransientModel):
_name = 'my.wizard'
_description = 'My Odoo 18 Wizard'
# Define a field for user input using short and familiar names.
user_input = fields.Char(string="User Input", required=True)
# Define a computed field that displays a result.
result = fields.Char(string="Result", compute="_compute_result", store=False)
@api.depends('user_input')
def _compute_result(self):
# Compute the result in an active voice manner.
for record in self:
if record.user_input:
record.result = record.user_input.upper()
else:
record.result = 'No Input Provided'
def action_apply(self):
# Execute logic when the user clicks the Apply button.
self.ensure_one()
# For example, log the current date and time.
self.env.cr.execute("SELECT NOW()")
return {'type': 'ir.actions.act_window_close'}As you see, every function and field is defined using active language. Moreover, the code computes a simple result based on user input and then closes the wizard window when the action is applied. In addition, the use of transition words in comments helps the reader follow the code’s logic easily.
Designing the Wizard View
Then, you must design an XML view that displays the wizard form. First, create the file my_wizard_view.xml in the views directory. Next, insert the following XML code:
<?xml version="1.0" encoding="UTF-8"?>
<odoo>
<!-- Create a form view for the wizard -->
<record id="view_my_wizard_form" model="ir.ui.view">
<field name="name">my.wizard.form</field>
<field name="model">my.wizard</field>
<field name="arch" type="xml">
<form string="My Odoo 18 Wizard Basics">
<group>
<field name="user_input" placeholder="Enter your text here..." />
<field name="result" readonly="1" />
</group>
<footer>
<button string="Apply" type="object" name="action_apply" class="btn-primary"/>
<button string="Cancel" class="btn-default" special="cancel"/>
</footer>
</form>
</field>
</record>
<!-- Create an action that opens the wizard form -->
<record id="action_my_wizard_form" model="ir.actions.act_window">
<field name="name">Odoo 18 Wizard Basics</field>
<field name="res_model">my.wizard</field>
<field name="view_mode">form</field>
<field name="target">new</field>
</record>
<!-- Add a menu item for the wizard -->
<menuitem id="menu_my_wizard" name="My Wizard" parent="base.menu_custom" action="action_my_wizard_form"/>
</odoo>Firstly, this XML code creates a form view for the wizard model. Then, it adds a footer with two buttons: one to apply the wizard’s action and one to cancel. Moreover, it defines an action that opens the wizard in a new modal window and links it to a menu item. Consequently, users can trigger the wizard easily from the Odoo interface.
Best Practices and Troubleshooting for Odoo 18 Wizards
Common Pitfalls and How to Avoid Them
Firstly, always verify that you inherit from the correct transient model. Then, use the proper namespace for your fields to avoid conflicts with other modules. In addition, ensure that all computed fields are correctly decorated with @api.depends when they rely on user input. Moreover, always test your wizard with various inputs to catch any unforeseen issues. Furthermore, be sure to include error messages that are clear so users understand what went wrong.
Enhancing User Experience with Wizards
Next, provide clear instructions on the form so users know what to expect. Additionally, you can add tooltips or help texts to your fields. Moreover, design the layout so that the wizard appears intuitive and uncluttered. In addition, always use active commands in your buttons (e.g., “Apply” instead of “Submit”). Finally, use transitional animations if possible, so that the wizard feels responsive and modern.
Advanced Wizard Techniques in Odoo 18
Dynamic Data Passing
Firstly, you can pass dynamic data between your wizard and the calling model. Then, add methods that compute values based on the context of the main form. In addition, you can use the context parameter in your action opening the wizard to pre-fill certain fields automatically. Furthermore, this technique increases the seamless integration between your module’s business logic and the wizard. For example, you might write a method that pre-populates a wizard field based on the active record’s data:
def open_wizard_with_context(self):
# Prepare context data and call the wizard with it.
return {
'type': 'ir.actions.act_window',
'res_model': 'my.wizard',
'view_mode': 'form',
'target': 'new',
'context': {
'default_user_input': self.name, # Pre-fill based on active record.
}
}This method actively uses context to pass default values. Moreover, it enables a more dynamic and interactive experience for the end-user.
Customizing Wizard Behavior
Next, you might want to adjust wizard behavior based on user actions or system events. Consequently, add custom methods to the wizard that trigger different business logic. Then, conditionally compute values based on the input. Additionally, you can extend wizard views with conditional visibility for certain fields, which makes the interface way more flexible. Furthermore, these customizations help tailor the wizard precisely to your business processes. In many real-world cases, developers design advanced wizards that change behavior according to user selection.
For example, you may dynamically modify field properties using Python code as follows:
def action_dynamic_change(self):
# Actively update the wizard based on user action.
for record in self:
if record.user_input and record.user_input.isdigit():
record.result = "Numeric Input Detected"
else:
record.result = "Text Input Detected"
return {'type': 'ir.actions.act_window_reload'}This function actively inspects the input and then changes the computed result based on the type of data entered. Moreover, it uses the transition command to reload the window so that the updated value is reflected without closing the wizard.
Testing and Debugging Your Wizard
Firstly, always test your wizard in different environments. Then, ensure that the business rules are enforced properly. In addition, use the Odoo developer mode to trace errors and log outputs. Furthermore, check the console for any Python tracebacks and resolve them immediately. Also, confirm that your computed fields update as expected and that the wizard closes gracefully after completing its tasks.
Debugging Tips
- Use Print Statements: Although not recommended in production, temporarily add print statements in your methods to display variable values. Then, remove them once debugging is complete.
- Check Context Values: Ensure that the context values passed from your calling action match the expected defaults.
- Review XML Syntax: Active voice and clear XML layouts help you spot minor mistakes such as missing field attributes.
Real-Life Use Cases for Odoo 18 Wizards
Managing Customer Input Efficiently
Firstly, many businesses use Odoo 18 wizards to capture real-time input from customers. Then, companies design wizards to help finalize orders or gather feedback. In addition, smooth wizard interfaces help reduce errors during data entry. Moreover, businesses save time by automating follow-up actions based on user submissions. For example, a wizard can help generate discounts or apply special pricing rules when order details are confirmed.
Streamlining Internal Processes
Next, wizards serve as an effective tool for internal processes. Consequently, a wizard may collect data before executing mass updates on records. Furthermore, it simplifies processes that require multiple confirmation steps. In addition, the interactive nature of wizards ensures that users complete necessary steps in the correct order. Then, you achieve higher data integrity across your applications as a result of these processes.
Interactive Reporting and Alerts
Moreover, advanced wizards are used to generate reports or alerts dynamically. For instance, a wizard can query the database based on date inputs and then display summary statistics. Additionally, by passing dynamic context, you can create interactive dashboards. Finally, these tools help business users rapidly analyze data without having to navigate through multiple screens.
Enhancing Your Wizard with CSS and JavaScript
Although Odoo 18 wizards are primarily back-end driven, you can also improve the look and feel with front-end enhancements. First, add custom CSS to style your wizard form. Then, include JavaScript extensions to manage interactive behavior.
Adding Custom CSS
Firstly, create a CSS file in your module that targets the wizard view. Then, link it in the manifest file under the assets section. In addition, use short and simple CSS selectors for quick styling changes. For example:
/* my_wizard_module/static/src/css/my_wizard.css */
.o_form_view .oe_title {
font-size: 18px;
color: #2d3436;
font-weight: bold;
}
.o_form_view .btn-primary {
background-color: #0984e3;
border-color: #0984e3;
}This code actively styles the title and primary buttons in your wizard form. Moreover, it ensures that the wizard stands out while remaining consistent with Odoo’s design guidelines.
Incorporating JavaScript for Interactivity
Next, you can create a JavaScript file to further enhance user experience by adding dynamic behaviors, such as live validation or auto-completion. Then, include this file in your module’s assets. For instance:
// my_wizard_module/static/src/js/my_wizard.js
odoo.define('my_wizard_module.my_wizard', function (require) {
"use strict";
var core = require('web.core');
core.action_registry.add('my_wizard_action', {
/**
* Actively initialize the wizard with dynamic validations.
*/
start: function () {
this._super.apply(this, arguments);
// Next, add a live-change event on the user input.
this.$('input[name="user_input"]').on('input', function () {
var value = $(this).val();
if (!isNaN(value)) {
$(this).css('border-color', 'green');
} else {
$(this).css('border-color', 'red');
}
});
return Promise.resolve();
}
});
});Firstly, this JavaScript file defines a module that enhances the wizard by validating the user’s input live. Then, when a user types in the input field, the border color changes based on whether the input is numeric or not. Moreover, the use of promises ensures that the wizard waits for initialization before responding to events.
Integrating the Wizard into Your Business Process
In addition to development, you must integrate your wizard with your existing business logic. Firstly, use the wizard to assist in processes such as mass price updates, data cleansing, or performing batch operations. Then, trigger the wizard action from menu items, buttons on other forms, or even automated server actions. Additionally, design your wizard to pass data back to the calling form effectively. Consequently, you increase user efficiency and reduce mistakes.
Example Integration Scenario
Imagine that your sales team needs to update the discount on several sale orders at once. First, you create a wizard that collects the discount percentage. Then, the wizard iterates over the selected sale orders and updates the discount field. In addition, you add a confirmation message to alert the user when the process is complete. The active implementation could look as follows:
from odoo import api, fields, models
class SaleOrderDiscountWizard(models.TransientModel):
_name = 'sale.order.discount.wizard'
_description = 'Wizard for Applying Discounts on Sale Orders'
discount = fields.Float(string="Discount (%)", required=True)
def apply_discount(self):
self.ensure_one()
active_ids = self.env.context.get('active_ids', [])
orders = self.env['sale.order'].browse(active_ids)
# Actively loop over the records and set discount values.
for order in orders:
order.write({'discount': self.discount})
return {'type': 'ir.actions.act_window_close'}Then, create the corresponding XML view and action so that the wizard is accessible from the sale orders list view. This integration actively leverages the wizard to make bulk updates and improves your business process.

_name = 'my.wizard'
_description = 'My Odoo 18 Wizard'
# Field to capture user input actively.
user_input = fields.Char(string="User Input", required=True)
# Computed field that turns the input into uppercase.
result = fields.Char(string="Result", compute="_compute_result", store=False)
@api.depends('user_input')
def _compute_result(self):
# Actively compute the result based on user input.
for record in self:
if record.user_input:
record.result = record.user_input.upper()
else:
record.result = 'No Input Provided'
def action_apply(self):
# Actively process the input and then close the wizard.
self.ensure_one()
self.env.cr.execute("SELECT NOW()")
