Pregunta 4

How can we integrate any API like Facebook with the Flask application?

We can integrate it easily with the help of the Flask extension named Flask-Social. It gives multiple access to users for other social platforms also. One thing we need to remember is that we have to use the Flask-Security extension of Flask for security purposes. For this, we need to install all social API libraries in Python. We have to register from an external API service provider.

Pregunta 5

Can you briefly talk about the Flask template engine?

The Flask template engine allows developers to create HTML templates with placeholders for dynamic data. Actually, a template is a file that contains two types of data, one is static and another is dynamic. Mostly this dynamic template is popular because the data is in run time. Flask allows the Jinja2 template engine to be used mostly as a template engine. Flask’s render_template method needs parameters and their values.

What are the features of forms extension in Flask?

We have to use the Flask- extension to implement forms in Flask. It’s called WTForms. It’s a Python-based rendering and validation library. It does data validation, CSRF protection, and internationalization. Once we use Flask-uploads, ReCaptcha from Flask-WTF helps to upload files. We can also manage JavaScript requests and customization of error responses.

Pregunta 7

Explain the G object in Flask?

If we want to hold any data during the application context, the Flask g object is used as a global namespace for keeping any data. It’s not suitable for storing data within requests. Actually, this letter g stands for global. Suppose we need to store a global variable in an application context, then g object is best in place of creating global variables. Here the g object will work as a request in a separate Flask g object. It always saves self-defined global variables.

Describe Flask memory management.

Memory management handles memory allocation in Python. Flask has a built-in garbage collector. It collects all wastage data and makes the space free. It manages memory by private heap space. This is not accessible by developers.

Few of them are accessed by users by using a few API tools. All data allocation is done by Flask memory management.

What do you know about the validators class of WTForms in Flask?

A Validator can take the input to check if it meets some criteria like string limit with returns. In case of failure, a validation error will come. This is a straightforward method. In Flask there are a few validator classes of WTForms. They are:

Pregunta 15

Explain Flask error handlers?

Generally, an HTTP error code will be returned when one error comes. Suppose the error code is within 400 to 499; then it is sure that a mistake is happening in the client-side request. Otherwise, if the error code is within 500 to 599, the error comes from a server-side request.

HTTP error code can show custom error pages to the user. This HTTPS error code is not set to the error handler’s code. While returning a message from the error handler, we have to include it.
