#<ActionController::ParameterMissing: param is missing or the value is empty: user>

Gone through a lot of answers but still couldn't find the solution. I have been trying to get a successful response for a POST request to the following controller,

def create
@user = User.new(user_params)

if @user.save
  render json: @user, status: :created, location: @user
else
  render json: @user.errors, status: :unprocessable_entity
end


private
 def user_params
  params.require(:user).permit(:name, :email, :phone, :password)
end
end

Although I send all the parameters mentioned,in the request,I am still facing the error.

"status": 400,
"error": "Bad Request",
"exception": "#<ActionController::ParameterMissing: param is missing or the value is empty: user>"

I am using rails version 5.2.1

This Worked for me. I made just only one hash in params method instead of nested hash. my user_params method was:-

def user_params
  params.permit(:name, :email, :phone, :password)
end

OR You can use your method but your parameter passed in user hash like below.

{user: {name: "bittu", email: "[email protected]", phone: 123456, password: "123456"  } }

If you look at the logs, what does the data transferred in your post request look like?

When you get that type of error, often it's because you send the data like this:

{ first_name: 'John', last_name: 'Doe', ...}

When the server expects you to nest this into a user object (hence the require(:user) in your strong_params:

{ user: { first_name: 'John', ... } }
