X-HTTP-Method-Override

[Shawn McDonald]

Is there a way to use an X-HTTP-Method-Override header with Grape?

If I write a PATCH request into my API, but send a PUT request with an X-HTTP-Method-Override header, I will receive a 405 response. Is there something I have to do in Grape, or do I need to set up some other type of middleware?

I think you just need to add Rack::MethodOverride into your middleware, above Grape.

I moved Rack::MethodOverride to the top, but this doesn't seem to prevent a 405 response.

Here's how it looks when I run rake middleware for the rails app:

use Rack::MethodOverride

use Rack::Cors

use ActionDispatch::Static

use Rack::Lock

use #<ActiveSupport::Cache::Strategy::LocalCache::Middleware:0x007fadcc1d7ca8>

use Rack::Runtime

use ActionDispatch::RequestId

use Rails::Rack::Logger

use ActionDispatch::ShowExceptions

use ActionDispatch::DebugExceptions

use ActionDispatch::RemoteIp

use ActionDispatch::Reloader

use ActionDispatch::Callbacks

use ActiveRecord::ConnectionAdapters::ConnectionManagement

use ActiveRecord::QueryCache

use ActionDispatch::Cookies

use ActionDispatch::Session::CookieStore

use ActionDispatch::Flash

use ActionDispatch::ParamsParser

use ActionDispatch::Head

use Rack::ConditionalGet

use Rack::ETag

use ActionDispatch::BestStandardsSupport

use OmniAuth::Builder

use OmniContacts::Builder

run MyApp::Application.routes

After playing with it, I realized that I can only override POST requests with an X-HTTP-Method-Override header. I can't override PUT/PATCH/DELETE/GET requests. Is this supposed to be the behavior of Rack::MethodOverride, or should there be a way to use it to override other types of requests?

[Shawn McDonald]

Never mind, I found that's the way it's supposed to behave in the source. I guess I'll have to write my own middleware or change the requests to POST.

Thanks for your help. Pointing me to Rack::MethodOverride put me on the right path.

If you write a middleware that does more than that, post a link here. Thx.
