Odoo 17 is a robust ERP (enterprise resource planning) platform with a reliable framework that is utilized by various organizations for rationalizing their business processes. The most crucial features that make Odoo easily tailored are its ORM (Object Relational Mapping), which lets developers effortlessly coordinate with the database and alter different components. One of those components is named as field properties, which can be easily accessed and changed with the help of the fields_get() method.

This whole guide will explain how to successfully utilize the fields_get() method, especially in Odoo 17, to make changes in field properties. We will have the proper syntax, various examples, and best methods to make the most out of this working. Moreover, we will also cover the significance of Odoo hosting solutions, managed Odoo server solutions, and Odoo server solutions, mainly at the time of dealing with modification. At last, we will also outline how Infinitive Host offers strong infrastructure to support such cutting-edge Odoo implementations.

Understanding the fields_get() Method in Odoo 17

The fields_get() method in the case of Odoo 17 is utilized to fetch important information about fields of any specific model. It gives a complete dictionary of field titles that consists of field names, attributes, and types. This get method can be mainly useful for changing field properties firmly and for debugging processes.

Advantages of Using fields_get():

Retrieve Field Metadata

The method access field attributes like field type, needed status, read-only status, and a lot more.

Dynamic Modification

Developers can easily customize field properties according to some specific conditions, making it very easy to modify the whole system for all users.

Increased Flexibility

It lets you know and link with the model’s structure, letting you properly manage how your fields behave across diverse modules.

Basic Syntax

The fields_get() method can be easily relied on any specific model in Odoo. Here is a general instance of how it runs:

class MyModel(models.Model):

    _name = 'my.model'

    def get_field_info(self):

        fields_info = self.fields_get(allfields=['field_name'], attributes=['type', 'required', 'readonly'])

        return fields_info

In the above instance, the fields_get() method fetches metadata for any particular field, like its type, if it is needed, or it is read-only.

Using fields_get(), Modify Field Properties 

Suppose that you have a custom model and you need to modify any field properties. For instance, you simply need to make a specific field optional or modify its read-only status according to some particular conditions, such as the present state of the record or user role. This can simply be attained with the help of the fields_get() method.

Example

Making any Specific Field Read-Only

With the help of the below code, you can make any required field read-only as per some conditions in the case of Odoo 17:

class SaleOrder(models.Model):

    _inherit = 'sale.order'

    def fields_get(self, allfields=None, attributes=None):

        res = super(SaleOrder, self).fields_get(allfields, attributes)

        # Example: Making the 'partner_id' field read-only if the order is confirmed

        if self.state == 'sale':

            if 'partner_id' in res:

                res['partner_id']['readonly'] = True

        return res

In this instance, the field with the name partner_id field will now become read-only if the order is properly confirmed. This dynamic modification can be personalized to various fields, providing reliability for different business requirements.

When to Use fields_get() for Customizations

The fields_get() method is mainly helpful when you want dynamic control over the behavior of all fields. Below-mentioned are various cases where this method excels:

Custom User Permissions

Make some fields read-only for several users or let the option of modifications mainly for admin users.

Dynamic Field Attributes

Change the attributes of any field according to the state of a record, like making a specific field optional or needed at diverse stages of a workflow.

Field Deprecation

Mark some fields as non-editable when they are not needed for a procedure.

Best Practices for Using fields_get()

Testing

Try to test your modifications many times in a development environment simply before implementing them on a live Odoo server. This makes sure that your customizations do not break previous working.

Optimize Conditions

When customizing chosen fields dynamically, ensure that you enhance your conditions to prevent unwanted database queries.

Use it Sparingly

Overutilization of the fields_get() method can always result in performance-related problems, mainly in models with numerous records. Utilize it wisely for dedicated, high-impact modifications.
