ruby grape post method insert multiple rows

Question

How to post multiple rows into DB using ruby Grape. For example when testing with CURL this is working fine

curl -H "Content-Type: application/json" -X POST \
     -d '{"name": "test", "age": "22"}' http://localhost:3000/students

But this is not working

curl -H "Content-Type: application/json" -X POST \
     -d '[{"name": "test", "age": "22"}, {"name": "someone", "age": "32" }]' \
     http://localhost:3000/students

This is my grape api code

post do
      student = Student.new
      student.name = params[:name]
      student.age = params[:age]
      student.save!
end

Answer 1

You use a bad syntax for JSON array object. Try this:

curl -H "Content-Type: application/json" \
     -X POST \
     -d '[{"name": "test", "age": "22"}, {"name": "someone", "age": "32" }]' \
     http://localhost:3000/students

EDIT :

If your payload is {"name": "test", "age": "22"} your code works. But you have a Array (params.kind_of?(Array)).

You can make this:

post do
  params.each do |student_params|
    student = Student.new
    student.name = student_params[:name]
    student.age = student_params[:age]
    student.save!
  end
end

Explanation:

params[:name]
# => nil
params.first[:name]
#=> test
