Rails Link_to is linking to undesired view

Question

My link_to in my view is going to a completely different "show.html.erb" than I'd like it to. I'm basically trying to understand why the "link_to @exhibit is linking to an "Investigation" profile. I think it may have to do with my routes file or the fact that its a "belong to" relationship...but can't seem to get it workin...what should that link_to be?

UPDATE: (AS PER BROIS QUESTION) The missing misbehaving link_to is in the <%= link_to @exhibit do %> in show.html.erb

MY EXHIBIT.RB (MODEL)

class Exhibit < ActiveRecord::Base
  attr_accessible :content, :investigation_id, :name, :user_id, :media, :media_html
  belongs_to :investigation

  has_many :categorizations
  has_many :categories, :through => :categorizations

  validates :name, presence: true, length: { maximum: 140 }
  validates :content, presence: true
  default_scope -> { order('created_at DESC') }

  auto_html_for :media do
  html_escape
  image
  youtube(:width => 400, :height => 250)
  link :target => "_blank", :rel => "nofollow"
  simple_format
end

MY EXHIBIT CONTROLLER:

class ExhibitsController < ApplicationController
include AutoHtml

def new
@exhibit = Exhibit.new
end

def show
@exhibit = Exhibit.find(params[:id])
end

def index
@exhibits = Exhibit.paginate(page: params[:page])
end

def create
  @investigation = Investigation.find(params[:investigation_id])
  @exhibit = @investigation.exhibits.create(params[:exhibit])
  if @exhibit.save
  flash[:success] = "You've successfully added etc etc..."
  redirect_to investigation_path(@investigation)
  else
  render 'new'
  end
end

end

MY ROUTES.RB

resources :sessions, only: [:new, :create, :destroy]

resources :investigations do
resources :players
end

resources :investigations do
resources :exhibits
end

LASTLY MY SHOW.HTML.ERB (INVESTIGATION PROFILE)

<% @investigation.exhibits.each do |exhibit| %>
  <div class="row-fluid services_circles">
    <%= link_to @exhibit do %>
    <div class="media">
      <div class="pull-left">
        <%= exhibit.media_html %>
      </div>
      <div class="media-body">
        <h4 class="media-heading"><%= exhibit.name %></h4>
        <p><%= exhibit.content %></p>
      </div>
    </div>
    <% end %>
<% end %>

ADDED THE INVESTIGATIONS CONTROLLER

class InvestigationsController < ApplicationController


def new
  @investigation = Investigation.new
end

def show
   @investigation = Investigation.find(params[:id])
end

def index
  @investigations = Investigation.paginate(page: params[:page])
end

def create
  @investigation = Investigation.new(params[:investigation])
  if @investigation.save
    flash[:success] = "You've successfully created..."
    redirect_to @investigation
  else
    render 'new'
  end
end

end

ADDED THE INVESTIGATION MODEL

class Investigation < ActiveRecord::Base
  # belongs_to :user

  has_many :players, dependent: :destroy
  has_many :exhibits, dependent: :destroy


  default_scope -> { order('created_at DESC') }
end

I appreciate the help...if i need to post any more info just let me know

Answer 1

IN YOUR : app/contorollers/exhibits_controller.rb

def show
@investigation = Investigation.find(params[:investigation_id])
@exhibit = Exhibit.find(params[:id])
end

IN YOUR : app/views/exhibits/show.html.erb

<%= link_to investigation_exhibit_path(@investigation, @exhibit) do %>

Maybe, I think.
