e-Zest Interview Questions and Answers

There are three types of inheritance in Odoo: model inheritance, view inheritance, and functional inheritance.

• Model inheritance allows a new model to inherit fields and methods from an existing model.

• View inheritance allows modifying existing views by adding or removing elements.

• Functional inheritance involves extending the behavior of a method without modifying the original code.

• Example: In model inheritance, a new mo...read more

SQL query to fetch second highest salary from employee table

• Use ORDER BY clause to sort salaries in descending order

• Use LIMIT to fetch only the second row

• Consider handling cases where there may be ties for the highest salary

Tuples are immutable in Python, so you cannot add elements directly. Instead, create a new tuple with the desired elements.

• Tuples are immutable, meaning you cannot change them after creation.

• To 'add' elements, create a new tuple that combines the original and new elements.

• Example: original = (1, 2, 3); new_element = 4; new_tuple = original + (new_element,)

• You can also use tuple unpacking: new_tuple = (*original, new_el...read more

Arrays are fixed in size and contain elements of the same data type, while lists are dynamic and can hold elements of different data types.

• Arrays are fixed in size, while lists are dynamic and can grow/shrink as needed.

• Arrays can only hold elements of the same data type, while lists can hold elements of different data types.

• Arrays are more memory efficient compared to lists.

• In Python, arrays are implemented using the '...read more

In Odoo, 'depends' and 'onchange' are decorators used to manage field dependencies and trigger actions on field changes.

• 'depends' is used to specify fields that a computed field depends on, ensuring it updates when those fields change.

• Example: @api.depends('field1', 'field2') defines a computed field that recalculates when field1 or field2 changes.

• 'onchange' is used to trigger a method when a field's value changes in t...read more

You can trigger a compute method every time by setting the 'compute' attribute in the field definition.

• Set the 'compute' attribute in the field definition to trigger the compute method every time the field is accessed.

• Ensure that the compute method is properly defined to perform the desired computation.

• Use the '@api.depends' decorator to specify the dependencies for the compute method.

• Avoid using the 'store' attribute ...read more

To create a new branch in git, use the 'git checkout -b' command.

• Use 'git checkout -b ' to create and switch to a new branch

• Alternatively, use 'git branch ' to create a new branch and then 'git checkout ' to switch to it

• Make sure to commit any changes before creating a new branch

Functions and methods are both blocks of code that can be called to perform a specific task, but methods are functions that are associated with an object.

• Functions are standalone blocks of code that can be called independently.

• Methods are functions that are associated with a specific object or class.

• Functions can be defined using the 'def' keyword, while methods are defined within a class.

• Example: 'def my_function():' ...read more

Property fields in Odoo are fields that are computed based on other fields or methods.

• Property fields are not stored in the database but are computed on the fly when accessed.

• They are defined using the @property decorator in Python.

• Property fields are useful for displaying calculated values without storing them in the database.

• Example: calculating the total price of a sale order based on the unit price and quantity.

Context and domain are used in Odoo to filter records in views and models respectively.

• Context is used to pass additional information to the server when performing actions like creating, updating, or deleting records.

• Domain is used to filter records in models based on certain conditions.

• Example: context={'lang': 'en_US'} will set the language to English for the current session.

• Example: domain=[('field_name', '=', 'valu...read more

Security in Odoo can be managed through user roles, access rights, and authentication mechanisms.

• Define user roles with specific access rights to restrict permissions.

• Set up strong authentication mechanisms like two-factor authentication.

• Implement secure coding practices to prevent common vulnerabilities like SQL injection or cross-site scripting.

• Regularly update Odoo to patch security vulnerabilities and stay protecte...read more

No, onchange field value is not stored in the database.

• Onchange field value is only temporarily stored in memory during the current session.

• The value is not saved to the database until the record is saved.

• Onchange methods are used to update the UI based on user input without saving to the database.

Server action and schedule action are tools in Odoo for automating tasks and actions within the system.

• Server action is a predefined sequence of actions that can be triggered manually or automatically based on certain conditions.

• Schedule action is a way to automate the execution of server actions at specific times or intervals.

• Server actions can be used to perform tasks like sending emails, updating records, or generat...read more

Lambda function is an anonymous function in Python that can have any number of arguments, but can only have one expression.

• Lambda functions are defined using the lambda keyword.

• They are commonly used for small, one-time operations.

• Lambda functions can be used as arguments to higher-order functions like map, filter, and reduce.

• Example: lambda x: x*2 defines a lambda function that doubles the input x.

Smoke testing is a quick test to check if the build is stable, sanity testing is a subset of regression testing focusing on specific areas, and regression testing is a comprehensive test to ensure no new bugs are introduced.

• Smoke testing is a preliminary test to check if the critical functionalities work without major issues after a build is deployed.

• Sanity testing is a subset of regression testing that focuses on spec...read more

Status codes in API testing indicate the outcome of the request made to the API.

• 200 - OK: Request was successful

• 201 - Created: Request resulted in a new resource being created

• 400 - Bad Request: Request was invalid

• 401 - Unauthorized: Request requires authentication

• 404 - Not Found: Resource not found

• 500 - Internal Server Error: Server encountered an error

Types of Authentication and authorization in API testing

• Basic Authentication

• OAuth

• API Keys

• JWT (JSON Web Tokens)

• Digest Authentication

Use SQL queries to fetch records based on conditions

• Use SELECT statement to fetch records

• Add WHERE clause to specify conditions

• Use operators like =, >, <, etc. to define conditions

• Consider using JOIN for fetching records from multiple tables

Our organization follows a CI/CD process to automate the software delivery pipeline.

• Continuous Integration (CI) involves automatically building and testing code changes frequently.

• Continuous Deployment (CD) automates the deployment of code changes to production.

• We use tools like Jenkins, GitLab CI/CD, and Docker for CI/CD.

• CI/CD helps in reducing manual errors, improving code quality, and speeding up the release process...read more

K8 namespace is a way to organize resources in Kubernetes, while configmap is used to store configuration data.

• Kubernetes namespaces provide a way to divide cluster resources between multiple users or teams.

• Configmaps are used to store non-sensitive configuration data in key-value pairs.

• Configmaps can be mounted as volumes or used as environment variables in pods.

• Example: kubectl create namespace my-namespace
