Well, I hate using SO as just a syntax checker, but for the life of me I cannot figure out why I get thi error
where line #8 raised:
unexpected $end, expecting keyword_end
Here is the offending code:
5: <%= f.input :allele2 %>
6: <%= f.input :run_date %>
7:
8: <%=f.association :gmarkers, :collection => Gmarker.all(:order => 'marker'), :prompt => "Choose a Marker", :label => "Marker" %>
9:
I'm using the SimpleForm gem, and am not too familiar with it yet (obviously!)
tia,

You're missing an <% end %> after your last line there, line 8.

I was trying to pass the rand_task output object to the _rand_show.html.erb and afterwartds call a new editable form only for the attr i'm intressted in by the id
form:
<%= form_for(#task = Task.new) do |f| %>

<%= f.label :name %><br />
<%= f.text_field :name, :disabled=>true %>
</div>
<div class="field">

random method:
def rand_task
if params[:id] == 'random'
#task = Task.order('RANDOM()').first
else
#task = Task.order('RANDOM()').first // if not i get a nill related error.
end
end
Please help why do i get the above mentioned error? IS the concept i'm thinking about wrong?
<%= form_for (:task, :url => {:action =>'rand_task'}) do |f| %>

The problem is the space between form_for and (. If you remove the space it should work.
Im getting the following error message:

I really can't figure out why I can't access the user_id field for the class Post. I have it as a field in my database (I can see it, and it isn't blank. Yet for some reason, I'm getting this error:
undefined method `user_id' for #<Class:0x103497448>
Extracted source (around line #10):
7: <h2>Topics</h2>
8: <% #board.topics.each do |topic| %>
9: <% #post = topic.posts(1) %>
10: <b><%= User.find(#post.user_id).username %> says <%= link_to topic.subject, [#board, topic] %></b><br />
11: <% end %>
12: <% end %>
13:
topic.posts(1) will return an array. Hence #<Class:0x103497448>
The right way to get the first post for a topic would be
9: <% #post = topic.posts.first %>
10: <b><%= User.find(#post.user_id).username %> says <%= link_to topic.subject, [#board, topic] %></b><br />
Try <% #post = topic.posts.limit(1) %>
hi i am using show_for gem and it gives me error like: undefined method `to_key' for # in app/views/messages/index.html.erb where line #46 raised:
my view look like these:
46: <%= show_for #messages do |s| %>
47: <%= s.attribute :subject %>
48: <%= s.attribute :message %>
49: <% end %>
my controller code look like:
#messages= Message.all
please help me what i am doing wrong. thanks in advance
I do not know this gem but according to its documentation, show_for is not supposed to receive a collection as argument (#messages) but a single object. I might be wrong.
With this supposition, I would to :
<% #messages.each do |message| %>
<%= show_for message do |s| %>
<%= s.attribute :subject %>
<%= s.attribute :message %>
<% end %>
<% end %>

I have tried altering the the quotes and brckets and different errors are listed but the problem doesn't go away.
Any help would be great thanks.
You need commas between the arguments in the image_tag method:
<%= image_tag('logo.png', :alt =>'Sample App', :class =>"round" ) %>
