rails print array values within form

Question

I'm stuck. On edit I grab a handful of data from the database and print the values in input fields. That part is working well. I want to print on the values without using a text field but can't seem to figure out how.

Form:

 <%= form_for(@post, :html => {:multipart => true}) do |f| %>

Currently working for printing my title value from the database into text field:

 <%= f.text_field :title, :size => "65%" %>

Controller:

def edit
    @post = Post.find(params[:id])
end

I've tried quite of bit of variations, but I'm a newbie.

<%= post.title %>
<%= @post.title %>
<%= f.title %>
<%= :title %>(lol)

Thanks in advance for the help!

<%= @post.title %> should work. what is your error?

Few things you can try:

1) Verify that the post with the ID really has a title.

rails c, then p = Post.find_by_id(5) (assuming that's the params[:id]) then check with p.title

2) There are 2 ways you can print the title. One way you have already tried @post.title. The other way is f.object.title. Therefore, only the second of your variations work.

Thanks for the rails console tip. I need to start using that. I know some mysql pretty well but very new to sqlite. There was no title for the record lol. Thanks for the sanity check! @post.title on a record with a title prints just fine.

No problem! Rails console is your friend. :)
