ActionView::MissingTemplate: ActionView::MissingTemplate: Missing template /members with {:locale=>[:en], :formats=>[:html],

Question

An integration test is returning a 'Missing Template' error. The microposts_interface_test.rb errors on /members. It may be because the /members view uses the MicropostsController but I'm unsure how to fix the test.

MicropostsInterfaceTest:

require 'test_helper'

class MicropostsInterfaceTest < ActionDispatch::IntegrationTest

  def setup
    @user = users(:michael)
  end

  test "micropost interface" do
    log_in_as(@user)
    get members_path
    assert_select 'div.pagination'
    assert_select 'input[type=file]'
    # Invalid submission
    assert_no_difference 'Micropost.count' do
      post microposts_path, micropost: { content: "" }
    end
    assert_select 'div#error_explanation'
    # Valid submission
    content = "This micropost really ties the room together"
    picture = fixture_file_upload('test/fixtures/rails.png', 'image/png')
    assert_difference 'Micropost.count', 1 do
      post microposts_path, micropost: { content: content, picture: picture }
    end
    assert assigns(:micropost).picture?
    assert_redirected_to root_url
    follow_redirect!
    assert_match content, response.body
    # Delete a post.
    assert_select 'a', text: 'delete'
    first_micropost = @user.microposts.paginate(page: 1).first
    assert_difference 'Micropost.count', -1 do
      delete micropost_path(first_micropost)
    end
    # Visit a different user.
    get user_path(users(:archer))
    assert_select 'a', text: 'delete', count: 0
  end

  test "micropost sidebar count" do
    log_in_as(@user)
    get members_path
    assert_match "#{@user.microposts.count} microposts", response.body
    # User with zero microposts
    other_user = users(:mallory)
    log_in_as(other_user)
    get members_path
    assert_match "0 microposts", response.body
    # Create a micropost.
    other_user.microposts.create!(content: "A micropost")
    get members_path
    assert_match "1 micropost", response.body
  end
end

Update:

# controller/members_controller.rb

class MembersController < ApplicationController
    before_filter :logged_in_user
  def index
    @micropost = current_user.microposts.build
    @feed_items = current_user.feed.paginate(page: params[:page])
  end
end

I confirm there is a specific index view at app/views/members/index.html.erb.

Update 2:

# controller/microposts_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_path
    else
      @feed_items = []
      render members_path
    end
  end

  def destroy
    @micropost.destroy
    flash[:success] = "Micropost deleted"
    redirect_to request.referrer || members_path
  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_path if @micropost.nil?
    end
end

Answer 1

In the create action in the MicropostController use render "members/index" instead of render members_path. Note that render does not load the variables needed in members/index, it only loads the template so add @micropost = [] just like you did for @feed_items = [] so that if you are calling those variables from the view you don't get an error of can't find variable @microposts. Or you can simply redirect_to members_path.
