Display "micropot feed" from a Rails tutorial in a custom place / view?

I followed Michael Hartl's "Rails Tutorial" and should display the "microflow feed" in the user location (/ members) and not in the root of the site.

I updated the SessionController so that when the user logs in, they are redirected to the new url, but there are two assertions required to submit members that cause errors and prevent the page from loading with the micropost feed.

# app/views/members/index.html.erb
<%= render 'shared/micropost_form' %>
<%= render 'shared/feed' %>

      

        
        
        
      

    

First error:

ArgumentError in MembersController#index
First argument in form cannot contain nil or be empty

      

        
        
        
      

    

return raise ArgumentError, "First argument in form cannot contain nil or be empty" unless object

and the second error (seen when removing the first render statement) returnsundefined method 'any?' for nil:NilClass

Part of the problem is that rendering a "microflow feed" in /members

for app/views/members/index.html.erb

seems to need access to app/controllers/microposts_controller.rb

, and I'm not sure how to deal with that.

Update:

micropost_controller.rb

# controllers/micropost_controller.rb

class MicropostsController < ApplicationController
  before_action :logged_in_user, only: [:create, :destroy]
  before_action :correct_user,   only: :destroy

  def create
    @micropost = current_user.microposts.build(micropost_params)
    if @micropost.save
      flash[:success] = "Micropost created!"
      redirect_to '/members'
    else
      @feed_items = []
      render '/members'
    end
  end

  def destroy
    @micropost.destroy
    flash[:success] = "Micropost deleted"
    redirect_to request.referrer || '/members'
  end

  private

    def micropost_params
      params.require(:micropost).permit(:content, :picture)
    end

    def correct_user
      @micropost = current_user.microposts.find_by(id: params[:id])
      redirect_to '/members' if @micropost.nil?
    end
end

      

        
        
        
      

    

_micropost_form.html.erb

# shared/_micropost_form.html.erb

<%= form_for(@micropost, html: { multipart: true }) do |f| %>
  <%= render 'shared/error_messages', object: f.object %>
  <div class="field">
    <%= f.text_area :content, placeholder: "Compose new micropost (420 chars max)..." %>
  </div>
  <%= f.submit "Post", class: "btn btn-primary" %>
  <span class="picture">
    <%= f.file_field :picture, accept: 'image/jpeg,image/gif,image/png' %>
  </span>
<% end %>

<script type="text/javascript">
  $('#micropost_picture').bind('change', function() {
    size_in_megabytes = this.files[0].size/1024/1024;
    if (size_in_megabytes > 5) {
      alert('Maximum file size is 5MB. Please choose a smaller file.');
    }
  });
</script>

      

        
        
        
      

    

_feed.html.erb

# shared/_feed.html.erb

<% if @feed_items.any? %>
  <ol class="microposts">
    <%= render @feed_items %>
  </ol>
  <%= will_paginate @feed_items %>
<% end %>

      

        
        
        
      

    

MembersController (updated with @Mandeep suggestion below)

class MembersController < ApplicationController
  def index
    @micropost = current_user.microposts.build
    @feed_items = current_user.microposts
  end
end
