Filtering Questions (posts) by tag_name in TagController#index passing /tags?tag_name=something
- by bgadoci
I am trying to get my TagsController#index action to display only the Questions that contain certain tags when passing the search parameter tag_name. I am not getting an error just can't get the filter to work correctly such that upon receiving the /tags?tag_name=something url, only those questions are displayed . Here is the setup:
class Tag < ActiveRecord::Base
belongs_to :question
def self.search(str)
return [] if str.blank?
cond_text = str.split.map{|w| "tag_name LIKE ? "}.join(" OR ")
cond_values = str.split.map{|w| "%#{w}%"}
all(:order => "created_at DESC", :conditions => (str ? [cond_text, *cond_values] : []))
end
end
and
class Question < ActiveRecord::Base
has_many :tags, :dependent => :destroy
end
tag link that would send the URL to the TagsController looks like this:
<%= link_to(tag_name, tags_path(:tag_name => tag_name)) %>
and outputs:
/tags?tag_name=something
In my /views/tags/index.html.erb view I am calling the questions by rendering a partial /views/questions/_question.html.erb.
<%= render :partial => @questions %>
When I send the URL with the search parameter nothing happens. Here is my TagsController#index action:
def index
@tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5
@tagsearch = Tag.search(params[:search])
@tag_counts = Tag.count(:group => :tag_name,
:order => 'count_all DESC', :limit => 100)
@questions = Question.all( :order => 'created_at DESC', :limit => 50)
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @tags }
end
end
How can I properly filter questions displayed in the /views/tags/index.html.erb file for the parameter tag.tag_name?
