Why is this not working?

I need help with this code. 

<div class="page-header">

  <h1> SINNERS Statuses </h1>

</div>

<% @statuses.each do |status| %>

  <div class="status">

    <strong> <%= status.name %> </strong>

    <p> <%= status.content %> </p>

  </div>

<% end %>

This part is giving me errors and is stopping me from learning. 

<p> <%= status.content %> </p>

The link to the instructors video is right here.

There you go, that should answer your question. You don't have a member named "content" in your "status" class. Sorry, I don't know how your code is structured, I just assume that they are missing what you are trying to access.

Well, I give up, this is too hard, as I was instructed to install devise, once installed they had told me to delete a particular file Ruby terminal failed, crashed then saved and lost all my progress.

Sorry to hear that, I thought that you were working through the Ruby lesson, but it turned out that you are just at the beginning. Don't give up, maybe I did not lead you to the correct answer due to misunderstanding. You should freshly repost your question so that someone else will give it a try.

I think I am going to try to use Node.js to try and achieve what I was doing.

To pass the challenge, replace the "strong" tag with "h2" tag

<h2> <%= status.name %> </h2>

It is not a challenge. I am actually moving along with the video it self when I input the code it will give me an error for the webpage.

Here is a screenshot. http://gyazo.com/eea9f3128345bb559c1bd5cbda44597e

maybe because your "status" object does not have/contain the key named "content"? Just guessing according to the error.

So how would I go about resolving this error?

I have not taken this course, but I assume that each "status" object supposed to be constructed to include a key named "content" and a value for the key. Look in your object constructor to see if you have that.

I am sorry, but I have no clue what I am supposed to do.

What happens when you delete the line <p> <%= status.content %> </p>?

I looked in the project download files, it has this file to create the database structure for statuses (I added the // to keep the text from disappearing)

//class CreateStatuses < ActiveRecord::Migration

// def change

// create_table :statuses do |t|

// t.string :name

// t.text :content

// t.timestamps

// end

// end

//end

AND the status class

//class Status < ActiveRecord::Base

// attr_accessible :content, :name

//end

Each status in statuses has a field named "content". Your error message says that "content" is not defined, check if you forgot to include the field "content" when you followed along with the instruction.

Sorry, but I am completely bad at this, what do I do with that code? Which file do I look in, and what code do I make sure there is to determine if it is missing?

Hi, I was looking at the instructor's project file download. I am assuming that your project structure is the same. I don't know how you created your files, that is why I suggested that you look into those files.

What happens when you delete the line < p > < % = status.content % > < / p > from your code above, did the error go away?

Leon Kenedy

The error does go away. However, I need this code to access their messages.
