I have a Posts resource which belongs to a Poster(a user type) whose address is geocoded using the Geocoder gem successfully upon registration. Now I want a user to able to search for posts near them by distance. I am relatively new to Rails, any help would be greatly appreciated.
I get the following error (I don't really know what it means, I thought setting up associations in my models was enough)
Cannot visit ActiveRecord::Relation::ActiveRecord_Relation_Poster
index.html.erb
<%= form_tag posts_path, method: :get do %>
Find postings <%= select_tag "within", options_for_select([["Next door", 0.001],["In your neighborhood", 0.05], ["Nearby", 0.1]], ["Nearby", 0.1]) %>
<%= submit_tag "Find", :name => nil %>
<% end %>
posts_controller.erb
def index
if params[:within]
@posts= Post.where(Poster.near(current_user, params[:within].to_f))
else
@posts=Post.all
end
end
Posts model
class Post < ActiveRecord::Base
belongs_to :poster
end
Poster model
class Poster < User
has_many :posts, dependent: :destroy
end
User Model
class User < ActiveRecord::Base
def full_address
[address_one, city, state, zip].compact.join(', ')
end
geocoded_by :full_address, :latitude => :lat, :longitude => :long
after_validation :geocode, if: -> (full_address){ full_address.present? or address_changed? }
end
I just ended up passing the attributes on the creation of the post, I wish there were a way to solve my original problem (makes the database less redundant)
in my Post Controller
def create
@post = current_user.posts.build(post_params)
@post.assign_attributes(:lat => current_user.lat, :long => current_user.long)
end
def index
if params[:within]
@posts= Post.near(current_user, params[:within].to_f)
else
@posts=Post.all
end
end
Also used "geocoded by :poster" in my Posts model
