Rails接收HTTP POST请求

Question

I have a Rails app which receives a POST request from a NGINX Module. The request looks like as follows:

Parameters: {"name"=>"asdadsasdads", "type"=>"live"}

I want to take the name and check in my Database if its the same, if yes I want to give a 200 back, if not 404.

def publish
  ssss = Ssss.find_by_name(params[:id])
  if ssss.name == params[:name]
    head 200, content_type: "text/html"
  else
    head 404, content_type: "text/html"
  end
end

This gives me a 500 Internal Server error.

If I remove the "ssss.name" and make a ":name" (I was just testing around) it gives me a 404. And if I remove the "head 404, content_type: "text/html" from the else statement it gives me 200, but then every request will pass through, even if it's not the same as in my DB.

I am not understanding how this even should work and I have a hard time googling. Can someone help me please? What would be correct?

Thanks!

Update 1:

def publish
  ssss = Ssss.find_by_name(params[:name])
  if ssss == params[:name]
    head 200, content_type: "text/html"
  else
    head 404, content_type: "text/html"
  end
end

That's what I am using right now. It gives me a 404 even though it should be fine?!

"name"=>"55b5807bbde1", "type"=>"live"}
Ssss Load (0.1ms)  SELECT  "ssss".* FROM "ssss" WHERE "ssss"."name" = ? LIMIT 1  [["name", "55b5807bbde1"]]

If I change it to find(params[:id]), it gives me a 500

Answer 1

It would appear that your problem as of this writing is that you are storing an object of class Ssss in the variable ssss , then comparing this object to a String . This will return false because the objects are not of the same class, throwing you into the 404 block.

Try comparing Ssss.name to params[:name] and see what you get.
