Hi!
Here is what I think it the most relevant part of the home view,
# Renders the menu
<%= render "shared/categories" %>
.
.
.
# Renders ads, unless its empty
<div class="right_container body_copy">
<% if @ads.empty? %>
Hittade inga annonser.
<% else %>
<%= render @ads %>
<% end %>
</div>
<div class="paginate body_copy">
<%= will_paginate @ads, :previous_label => t(:previous), :next_label
=> t(:next) %>
</div>
I'm getting "Hittade inga annonser" which means "Couldn't find any
ads" when I click on the link, but it shouldn't be empty. It should
render all ads that matches a certain condition, for example, :gender
=> 'female', category => ' accessories'. I have checked the database
and it should get two rows.
It works when I have methods like this:
def female_accessories
@ads = Ad.find_all_by_gender_and_category('dam',
'Accessoarer').paginate(:page => params[:page])
@title = "Startsidan"
render 'home'
end
But this isn't very DRY, since I would need to have an action for
every category. I want something slightly more dynamic.
I hope i'm understandable.
Tips and links regarding ruby-debug would be really nice!
Thanks!
