Ruby on Rails将嵌套的哈希值发布到强参数

Question

I'm posting a hash from my ruby app, to an api built in ruby using strong params.

My post looks like this:

resp = Net::HTTP.post_form(url, 'order' => @order.to_json, 'max' => '50')

The issue is, that this doesn't work with strong params

[3] pry(#<Api::V1::OrdersController>)> order_params
NoMethodError: undefined method `permit' for #<String:0x007feb6890acf8>

How do I post this correctly? Also, I'd like to post a nested has under order as well.

params[:order][:pickup_attribute]

How can I also send that through?

Answer 1

You are posting order as a String. Try this:

resp = Net::HTTP.post_form(url, 'order' => @order.as_json, 'max' => '50')

Notice the as_json (returns a Hash) instead of to_json (which returns a String). If it does not work, I would like to see your controller's implementation.
