Can't get past 'Unable to find field: content'

Is anyone else having this problem? I've been back through the video and checked my code but I just can't put a dent in that error. Is it a rails version thing? It all works fine when I just open the app and go through creating and editing a todo item myself, just not in this test

It is a while since I've done this course and I found it a huge struggle, I have to say.

I'm looking through my code and it is very different to yours but that's easily explained as I got almost to the end of the course before giving up on it completely!

Your test is taking a few steps - it is visiting the todo list, clicking on edit and is then attempting to complete a field called :content with a string. That's where it is struggling - it can't find a field called content. In my app there seems to be a couple of fields, :title and :description.

Anyway, here's my test: 

    it "is successful with valid content" do
        visit_todo_list(todo_list)
        within("#todo_item_#{todo_item.id}") do
            click_link "Edit"
        end
        fill_in "Content", with: "Lots of milk"
        click_button "Save"
        expect(page).to have_content("Saved todo list item")
        todo_item.reload
        expect(todo_item.content).to eq("Lots of milk") 
    end

So, change your :content to "Content", perhaps?

Hi Rob,

Which test is it, and what does your test & code look like?

Well, three different tests come up with that same error so I'm having trouble nailing down where the problem is. Jason fixes things without fixing that for a couple of minutes and somewhere in there I've missed something. I'm not sure what code to paste here but I think I've added:

  def edit
    @todo_list = TodoList.find(params[:todo_list_id])
    @todo_item = @todo_list.todo_items.find(params[:id])
  end

  def url_options
    {todo_list_id: params[:todo_list_id]}.merge(super)
  end

    it "is successful with valid content" do
       visit_todo_list(todo_list)
       within("#todo_item_#{todo_item.id}") do
           click_link "Edit"
       end
       fill_in :content, with: "Lots of Milk"
       click_button "Save"
       expect(page).to have_content("Saved todo list item")
       todo_item.reload
       expect(todo_item.content).to eq("Lots of Milk")
    end

and copied the new form over to the edit.html.erb file

Thanks,

Rob

Bloody 'ell, that was it exactly. Thank you.

One little thing and it all flies out the window. Man I love/hate coding

Yeah - it is a bit like that at time!

The Ruby on Rails course can be quite tricky as you progress through it so don't struggle alone - keep asking questions when you get stuck. I hope you don't get stuck, obviously! :-)
