I am trying to make a post using Postman on my Rails app and I get an issue saying:

ActionController::ParameterMissing (param is missing or the value is empty: vendor
Did you mean?  vendor_data
               action
               quote_type
               controller):

This is my controller file where the params are called:

def create_vendor_params
    params.require(:vendor).permit(
      :vendor_id, :quote_type, :first_name, :last_name, :email, :phone_type, :phone, :request_type, :address1, :address_city, :address_state, :address_zip, :DOB
    )
  end

And this is the data I am sending from Postman. Now I am not sure if it's because renter_data it's nested and on my params permit:

{
    "vendor_id": 2,
    "quote_type": "renter",
    "renter_data": {
        "first_name":"Tony",
        "last_name":"Stark",
        "email":"tony@starkindustries",
        "phone_type":"mobile",
        "phone":"6504881234",
        "request_type":"renter",
        "address1":"123 Main Street",
        "address_city":"Palo Alto",
        "address_state":"CA",
        "address_zip":"94301",
        "DOB":"1990-07-22"
    }
}

Is this issue because of nested data inside renter_data? And if it is, how can I nest it?

EDIT

When I make the post I see an empty object at the end of the request:

Processing by Api::V2::LeadController#create as */*
      Parameters: {"vendor_id"=>2, "quote_type"=>"renter", "renter_data"=>{"first_name"=>"Tony", "last_name"=>"Stark", "email"=>"tony@starkindustries", "phone_type"=>"mobile", "phone"=>"6504881234", "request_type"=>"renter", "address1"=>"123 Main Street", "address_city"=>"Palo Alto", "address_state"=>"CA", "address_zip"=>"94301", "DOB"=>"1990-07-22"}, "vendor"=>{} <---HERE }

Why is that?

CodePudding user response：

This is the concept of nested strong params in create_vender_params function you have to add more permitted params

params.require(:vendor).permit(
  :vendor_id, :quote_type, renter_Data: [:first_name, :last_name, :email, :phone_type, :phone, :request_type, :address1, :address_city, :address_state, :address_zip, :DOB])

CodePudding user response：

There are two problems: First, the strong params expect the input to be nested under vendor. Second, the strong params do not expect a nested renter_data hash.

To fix this in your query change the structure of the request data to:

{
  "vendor": {
    "vendor_id": 2,
    "quote_type": "renter",
    "first_name":"Tony",
    "last_name":"Stark",
    "email":"tony@starkindustries",
    "phone_type":"mobile",
    "phone":"6504881234",
    "request_type":"renter",
    "address1":"123 Main Street",
    "address_city":"Palo Alto",
    "address_state":"CA",
    "address_zip":"94301",
    "DOB":"1990-07-22"
  }
}

If you want to keep the nested renter_data hash then you have to change the strong params like Paarth Agrawal already suggested. But then you still need to nest everything under vendor.
