How to convert for saving the data coming from the client side?

Question

Angular

There is an API in the form of a rail application, and a client application in Angular.js.
Should I strive to achieve a state where data from the client comes 1 to 1, as needed, without the need for their mapping.
If not, then how to transform it so that it is DRY and generally beautiful?
Suppose a hash comes from the client containing the following data:
{
"name": "sample',
"tags": [
"non",
"adipisicing",
"deserunt",
"nulla",
"do",
"aute",
" enim"
]
}
On the client, you have to do something like:

AR::Transaction do
 if record.save
    tags.each do {|tag| record << tag.find_or_create_by(tag)}
 end
end

You can make some simple Form object.
What is the best approach to use? Or still try and add 1k1 data mapping?

Answer 1

Using, for example, Postgres and JSONB , you can save any hash and access the structures inside it as you like. Is this what your question is about?
