Rails & strong_parameters 'required parameter missing'

I'm working on creating 'retweet'(restream) functionality for one of my projects, but I keep running into this error:

Required parameter missing: restream

I'm not sure what I'm missing here. Here's my setup. Any ideas?

Models

#app/models/member.rb
Class Member < ActiveRecord::Base
    has_many :statuses
end

#app/models/status.rb
Class Status< ActiveRecord::Base
    belongs_to :member
    has_many :restreams, class_name: "Status", foreign_key: "restream_id"
end

Restream

#config/routes.rb
resources :statuses do
    member do
        post :retweet
    end
end

#app/controllers/statuses_controller.rb
def restream
    @restream = Status.new(restream_params)
    @restream.save
end

private

def restream_params
    params.require(:restream).permit(:restream_id, :content).merge(member_id: current_user.id)
end

#app/views/statuses/show.html.erb
<%= link_to image_tag("Re-Stream 3.png", class: "act_actions", title: "Restream", alt: "Restream"), restream_status_path(status.id), method: :post, :class => "btn restream" %>

You're not passing any params into the controller from your link_to. You need something like this:

<%= link_to image_tag("Re-Stream 3.png", class: "act_actions", title: "Restream", alt: "Restream"), restream_status_path(status.id, restream: my_restream_object), method: :post, :class => "btn restream" %>

Notice where I'm actually passing my_restream_object into the path as a URL parameter named restream.

Hope that helps!

Also, your route is called retweet instead of restream. :)

Sean Gaffney Ok that makes sense. So should the object I'm trying to pass be the actual status? Something like:

restream_status_path(status.id, restream: status)
