how do i list strings vertically down a website from a datab
hi, I need to set up a page that lists words vertically, these words will be read from a database. I would also like a text box at the bottom of the list ready to add new words to the database, then have the newly added word appear at the end of the list. I own the agile web dev with rails book, but I cant get a pure answer to my question from it. If you could just give me some lines of code you think would work that would be great. this is an example: hello whats up hi>>text box<< "how are you" (''how are you'' is entered into the text box)(the site will then reload and come back with this) hello whats up hi how are you>>text box<<-- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: how do i list strings vertically down a website from a datab
This would probably do what you want.... It would be more fun done
ajax calls (no page refresh) but this gives you the starting idea
---Controller
class SimpleListController < ApplicationController
def index
@items = SimpleList.find(:all, :order=>"id")
end
def create_item
unless params[:display_text].empty?
@items = SimpleList.create(:display_text=>params[:display_text])
end
redirect_to :action=>:index
end
end
---- View
<% for item in @items -%>
<%=item.display_text %><br>
<% end -%>
<% form_tag :action=>:create_item do -%>
<%=text_field_tag :display_text %>
<%=submit_tag "Add" %>
<% end %>

Re: how do i list strings vertically down a website from a d
Mr. Bris, Thank you for this code, this is definitely what I needed. There are a couple problems that I still need your help on; when I ran the code on localhost it came back with an error: Showing app/views/sample_list/add.rhtml where line #5 raised: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each Extracted source (around line #5): 2: <head> 3: <title>please enter a word...</title> 4: </head> 5: <% for item in @items -%> 6: <%=item.display_text %><br> 7: <% end -%> 8: <% form_tag :action=>:create_item do -%> It talks about an unexpected nil character, so I''m thinking that I should load the database with the first entry. If you think that is the case, should I do some type of migration to make a new table in the DB? In any event I would like to get your feed back.

Re: how do i list strings vertically down a website from a d
This should be the code in your migration file after you generated a
model...
class CreateSimpleLists < ActiveRecord::Migration
def self.up
create_table :simple_lists do |t|
t.column :display_text, :string
end
end
def self.down
drop_table :simple_lists
end
end
then "rake db:migrate"

Re: how do i list strings vertically down a website from a d
Mr. Bris I did the migration, it showed up in the database but I still get the same error. I tried putting something manually into the database, to have a string in there for the code to grab, but it would not let me. Is there anything else I''m not doing or seeing?

to load the db, I made an admin controller and put scaffold :sample in it, but the same error keeps coming up. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
