Hello,
I am having some trouble figuring out how to use the rateable plugin. i
followed as close as the directions located at
http://www.naffis.com/blog/articles/2006/08/31/rails-ajax-star-rating-system
but i fail at working it.
i am getting this error
You have a nil object when you didn''t expect it!
The error occured while evaluating nil.rating
Extracted source (around line #1):
1: <%= number_with_precision(asset.rating, 1) %>/5 Stars<br>
2: <ul class=''star-rating''>
3: <li class=''current-rating''
style=''width:<%= (asset.rating *
30).to_i -%>px;''>
4: Currently <%= number_with_precision(asset.rating, 1) %>/5
Stars.
....
the model i am trying to use rateable with is my address model (my
addresses table that contains name, zipcode, etc...)
if my view is this:
<% for column in Address.content_columns %>
<p>
<%= column.human_name %>:</b> <%=h @address.send(column.name)
%>
</p>
<% end %>
where do i add this?
<div id="star-ratings-block">
<%= render :partial => "rating/rating", :locals => { :asset
=> @asset }
%>
</div>
how does the rating system know to keep values for my address? dont i
need to make some sort of relationship?
thanks for any help!!!!!!

Dear Koloa:
I went through the walkthrough you linked to, and got past the issue you
encountered....
The error you are seeing has to do with the the fact that the partial is
referring to asset. You probably want to change that to something else
(as well as in the RJS code and the controller).
You also want to be careful with the line:
Rating.delete_all(["rateable_type = ''Posting'' AND
rateable_id = ? AND
user_id = ?", @posting.id, current_user_id.to_s])
current_user_id is a string in the migration described
If you (or anyone else) wants to see the code I came up with, please
email me.... I wrote a very simple app that lets you create postings
using scaffolding, and vote on them... The only thing that I''m not
happy
with is that after voting, the post name disappears! (and I am pretty
sure that has to do with the fact that the rate controller needs to do
something else that I''m not doing, but I''m not 100% sure....

Hello Dominique, Thanks for the reply. I seemed of gotten passed that problem but now i have a new one! when i click on the stars, no action seems to take place. i put printout statements to see if there is any action but nothing. is asset the model that is acting as rateable? if my model is address, do i set asset => @address in my view? also, do i move the rate function in the ratingController to my personal controller?

use the rated_by_user method @rate.rated_by_user?(@session[:user]) and user?

hello, how do i use this? do all sessions have user or do i have to define it in a session model? do i put this code in the rate function and if its true, return and do nothing? else, record the rating? thanks Dominique i still have a few questions about the plugin.. what is rateable_id and user_id in the rateable table? in my rate function, rateable_type = my model name, rateable_id = my model id, and user_id = also my model id. //my model == Address table. is this right?

rateable_id is the id of the table you are rating so for you, rateable_id will be equal to address_id user_id should be the id of the user who posts the rate, this is used to ensure that a user only rates something once. there is an example of my rating system at www.blogsaic.com it works pretty much like the rating system at youtube login and rate some tiles if you want a similar system, I can give you all the bits of code you need On 9/24/06, koloa <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote:> > > hello, > > how do i use this? do all sessions have user or do i have to define it > in a session model? > > do i put this code in the rate function and if its true, return and do > nothing? else, record the rating? > > > thanks Dominique > i still have a few questions about the plugin.. > > what is rateable_id and user_id in the rateable table? in my rate > function, rateable_type = my model name, rateable_id = my model id, and > user_id = also my model id. > > //my model == Address table. > > > is this right? > > > > > Dion Hewson wrote: > > use the rated_by_user method > > > > @rate.rated_by_user?(@session[:user]) and user? > > > > > > > > On 9/24/06, koloa <rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote: > >> my address ID) > >> > >> is this correct? > >> > >> -- > >> Posted via http://www.ruby-forum.com/. > >> > >> > > >> > > > > > > -- > > > > www.blogsaic.com > > search, post, blog > > > -- > Posted via http://www.ruby-forum.com/. > > > >-- www.blogsaic.com search, post, blog --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
