Ok, I am trying to display the profile pic of a user. The application I have set up allows users to create questions and answers (I am calling answers 'sites' in the code) the view in which I am trying to do so is in the /views/questions/show.html.erb file. It might also be of note that I am using the Paperclip gem. Here is the set up:
Associations
Users
class User < ActiveRecord::Base
has_many :questions, :dependent => :destroy
has_many :sites, :dependent => :destroy
has_many :notes, :dependent => :destroy
has_many :likes, :through => :sites , :dependent => :destroy
has_many :pics, :dependent => :destroy
has_many :likes, :dependent => :destroy
end
Questions
class Question < ActiveRecord::Base
has_many :sites, :dependent => :destroy
has_many :notes, :dependent => :destroy
has_many :likes, :dependent => :destroy
belongs_to :user
end
Answers (sites)
class Site < ActiveRecord::Base
belongs_to :question
belongs_to :user
has_many :notes, :dependent => :destroy
has_many :likes, :dependent => :destroy
has_attached_file :photo, :styles => { :small => "250x250>" }
end
Pics
class Pic < ActiveRecord::Base
has_attached_file :profile_pic, :styles => { :small => "100x100" }
belongs_to :user
end
The /views/questions/show.html.erb is rendering the partial /views/sites/_site.html.erb which is calling the Answer (site) with:
<% div_for site do %>
<%=h site.description %>
<% end %>
I have been trying to do things like:
<%=image_tag site.user.pic.profile_pic.url(:small) %>
<%=image_tag site.user.profile_pic.url(:small) %>
etc. But that is obviously wrong. My error directs me to the Questions#show action so I am imagining that I need to define something in there but not sure what. Is is possible to call the pic given the current associations, placement of the call, and if so what Controller additions do I need to make, and what line of code will call the pic?
UPDATE: Here is the QuestionsController#show code:
def show
@question = Question.find(params[:id])
@sites = @question.sites.all(:select => "sites.*, SUM(likes.like) as like_total",
:joins => "LEFT JOIN likes AS likes ON likes.site_id = sites.id",
:group => "sites.id",
:order => "like_total DESC")
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @question }
end
end
