JSON JBuilder

A Jbuilder file is a Ruby template that is used to generate JSON responses in Rails applications. Jbuilder files are typically used in conjunction with the render json: @object method to render a JSON object from a Ruby object.

Jbuilder files are similar to ERB files, but they use a different syntax for generating JSON objects. For example, the following code would generate a JSON object with the name, age, and email attributes:

json.name @user.name
json.age @user.age
json.email @user.email

The json.name method sets the name property of the JSON object to the value of the @user.name attribute. The json.age and json.email methods work in a similar way.

Jbuilder files can also be used to render nested JSON objects. For example, the following code would generate a JSON object with a contacts property that contains an array of contact objects:

json.contacts do
  json.array! @user.contacts, partial: 'users/contact'
end

The json.contacts method creates a new property called contacts in the JSON object. The json.array! method then renders an array of contact objects using the users/contact partial.

Jbuilder files are a powerful way to generate JSON responses in Rails applications. They provide a concise and easy-to-read syntax for generating JSON objects.
