I have reviewrequests that has many sitereviews. I can get at the count of the number of site reviews a given reviewrequest has in a view with: <%=h request.sitereviews.count.to_s %>
With each sitereview there's a text field - suggestions. Is there a way to get at say the last 5 sitereview.suggestions values as a single value? Something like: <%=h request.sitereviews.suggestions.last.5.to_s %>
You could add this to request.rb
def latest_suggestions
suggestions = []
sitereviews.find(:all, :order => 'created_at desc', :limit => 5).each do |sr|
suggestions << sr.suggestions
end
suggestions.join(',')
end
I'm guessing you mean that each site review has suggestions and you want to get the suggestions of the last 5 site reviews.
This is all pretty weird honestly, not sure why you would want this.

I haven't used case statements before and was wondering how to do the following.
I have a number of news pages, each having posts relevant to department, so the pages
/tynewyddnews
/woodsidenews
/outreachnews
/sandpipernews
On my home page I am grabbing the latest post from each of these and displaying them.
Post Model
def self.top_posts
#Array with each of the 4 departments - first record
top_posts = [
self.tynewydd_posts.first,
self.woodside_posts.first,
self.sandpiper_posts.first,
self.outreach_posts.first
]
#remove entry if nil
top_posts.delete_if {|x| x==nil}
return top_posts
end
tynewydd_posts for example is a scope
scope :tynewydd_posts, :include => :department, :conditions => {"departments.name" => "Ty Newydd"}, :order => "posts.published_on DESC"
So if i am reading a post on the home page from tynewydd and want to create a link to /tynewyddnews or i am reading a post from woodside and want to link_to /woodside I have been advised that a case statement may help, but I am unsure on what to use as parameters, so my attempt so far is
def public_news
case Post.top_posts
when :tynewydd_posts == 'Ty Newydd'
link_to('...Read more', tynewyddnews_path)
when :woodside_posts == 'Woodside'
link_to('...Read More', woodsidenews_path)
end
end
And then in my view i can call the helper
<%= public_news %>
obviously a miserable attempt, firstly in examples I have seen a variable is being set when the case is being set? if someone could give some advice on how to achieve this it would be much appreciated
Try this variant:
def public_news
path = case
when Post.tynewydd_posts then tynewyddnews_path
when Post.woodside_posts then woodsidenews_path
...
else default_path end
end
link_to('...Read More', path)
end
when expression will fire up when expression is evaluated to true
I have code that looks like this:
#all_ratings.each do |rating|
= check_box_tag "ratings[#{rating}]", session[:checkbox][rating], :id => "ratings_#{rating}"
...
= submit_tag 'Refresh', :id => "ratings_submit"
By saving the state of which checkboxes were clicked I hoped to be able to pre-check the boxes that were clicked after the request had gone through and the page reloads. The problem that I am having is that the code above doesn't seem to work. I'm not sure if it's because I have the :id => "ratings_#{rating}" bit at the end (which is required for this assignment). I checked out the rails api here, but that was as clear as mud. Thanks in advance for the help!
Cheers
(Disclaimer: This code is for HW 2 for Coursera's Software as a Service course - I have finished the bulk of the logic for the HW, but this last bit is beyond me and seems to be more of an idiosyncracy than a major topic, hence I am posting it here.)
What boolean variable did you add? Considering I have a model with has_many ratings, say Video, and have #video defined, I'd do
= check_box_tag "ratings[#{rating}]", session[:checkbox][rating], #video.ratings.include?(rating), :id => "ratings_#{rating}".
The #video.ratings.include?(rating) part prechecks the ratings associated to the current video. What are the associations related to your Rating model?
I'm using a select field in a Rails app that is NOT tied to a related model, but stores integer values for a static series of options , i.e.,
<%= select (:this_model, :this_field, [['Option1',1],['Option2',2],['Option3',3],['Option4',4]] ) %>
In a show/ index view, if I want to display the option text (i.e. Option1, Option2, etc) rather than the integer value stored in the database, how do I achieve this?
Thanks for helping a noob learn the ropes!
EDIT
Based on Thorsten's suggestion below, I implemented the following. But it is returning nil, and I can't figure out why.
Invoice model:
##payment_status_data = { 1 => "Pending Invoice" , 2 => "Invoiced" , 3 => "Deposit Received", 4 => "Paid in Full"}
def text_for_payment_status
##payment_status_data[payment_status]
end
Invoice show view:
Payment Status: <%= #invoice.text_for_payment_status %>
In the console:
irb > i=Invoice.find(4)
=> [#<Invoice id: 4, payment_status: 1 >]
irb > i.text_for_payment_status
=> nil
I've tried defining the hash with and without quotes around the keys. What am I missing?
something like this would work:
<%= form_for #my_model_object do |form| %>
<%= form.label :column_name "Some Description" %>
<%= form.select :field_that_stores_id, options_for_select({"text1" => "key1", "text 2" => "key2"}) %>
<% end %>
Update
If you later want to display the text you can get it from a simple hash like this:
{"key1" => "text 1", "key2" => "text2"}[#my_object.field_that_stores_id]
But you better store this hash somewhere in a central place like the model.
class MyModel < ActiveRecord
##my_select_something_data = {"key1" => "text 1", "key2" => "text2"}
def text_for_something_selectable
##my_select_something_data[field_that_stores_id]
end
end
Then you can use it in your views like
#my_object.text_for_something_selectable
There are many possible variations of this. But this should work and you would have all information in a central place.
Update
Ok, I used something similar for our website. We need to store return_headers for rma. Those need to store a return reason as a code. Those codes are defined in an external MS SQL Server Database (with which the website exchanges lots of data, like orders, products, and much more). In the external db table are much more return reasons stored than I actually need, so I just took out a few of them. Still must make sure, the codes are correct.
So here goes he model:
class ReturnHeader < AciveRecord::Base
##return_reason_keys = {"010" => "Wrong Produc",
"DAM" => "Damaged",
"AMT" => "Wrong Amount"}
def self.return_reason_select
##return_reason_keys.invert
end
def return_reason
##return_reason_keys[nav_return_reason_code]
end
end
Model contains more code of course, but that's the part that matters. Relevant here is, that keys in the hash are strings, not symbols.
In the views i use it like this:
In the form for edit:
<%= form_for #return_header do |form| %>
<%= form.label :nav_return_reason_code "Return Reason" %>
<%= form.select :nav_return_reason_code, options_for_select(ReturnHeader.return_reason_select, #return_header.nav_return_reason_code) %>
<% end %>
(Maybe no the most elegant way to do it, but works. Don't know, why options_for_select expects a hash to be "text" => "key", but that's the reason, why above class level method returns the hash inverted.)
In my index action the return reason is listed in one of the columns. There I can get the value simply by
#return_headers.each do |rh|
rh.return_reason
end
If you have trouble to get it run, check that keys a correct type and value. Maybe add some debug info with logger.info in the methods to see what actual data is used there.
Pretty much a noobie here, so I appreciate any help someone can give.
I'm trying to add faceting to the search on my site through Sunspot. Ryan just released a great Railscast which got me started: http://railscasts.com/episodes/278-search-with-sunspot. I got that working and was able to add additional facets. My problem is that the facets are independent of each other. If I have 3 facets on 3 different attributes, when I select a facet once I already have on selected, I would like to display only results falling into both of those facests. As of now, it just switches from one facet to the other. I feel like this shouldn't be that difficult, but I can't figure out how to do it.
I did find this tutorial: http://blog.upubly.com/2011/01/06/using-sunspot-in-your-views/ which I think is doing what I want. I tried to get this working but, even when I attempt to make it work with just one facet I don't any results listed. Just the facet name and then nothing else.
Thoughts?
Thank you!!
UPDATE
Here is the code samples of what I am trying to do:
Adjusting the Railscasts code I got this:
In my StylesController:
def index
#search = Style.search do
fulltext params[:search]
facet :departmental, :seasonal, :classifier
with(:departmental, params[:department]) if params[:department].present?
with(:classifier, params[:classification]) if params[:classification].present?
with(:seasonal, params[:season]) if params[:season].present?
end
In my Style Index view (I know I need to condense this)
= form_tag styles_path, :method => :get do
%p
= text_field_tag :search, params[:search]
= submit_tag "Search", :name => nil
#facets
%h4 Departments
%ul
- for row in #search.facet(:departmental).rows
%li
- if params[:department].blank?
= link_to row.value, :department => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :department => nil})
%h4 Classifications
%ul
- for row in #search.facet(:classifier).rows
%li
- if params[:classification].blank?
= link_to row.value, :classification => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :classification => nil})
%h4 Seasons
%ul
- for row in #search.facet(:seasonal).rows
%li
- if params[:season].blank?
= link_to row.value, :season => row.value
(#{row.count})
- else
%strong= row.value
(#{link_to "remove", :season => nil})
In my Style Model:
searchable do
text :number, :description, :department, :classification, :season
string :departmental
string :classifier
string :seasonal
end
def departmental
self.department
end
def classifier
self.classification
end
def seasonal
self.season
end
And my version of the upubly code, paired down to just try to get the "seasonal" facet working:
I left the the Search Partial, the Search Model and the SearchHelper the same as in the example. I tried to mess with the Helper as my Facets will be pulling text values, not just IDs of other Models, but to no avail. I don't have my various attributes set up as individual Models as I didn't think I needed that functionality, but I am starting to think otherwise.
StylesController:
def index
#title = "All styles"
#search = search = Search.new(params[:search]) # need to set local variable to pass into search method
#search.url = styles_path
#search.facets = [:seasonal]
#solr_search = Style.search do
keywords search.query
with(:seasonal, true)
search.facets.each do |item|
facet(item)
with(:seasonal, params[:season]) if params[:season].present?
end
any_of do
# filter by facets
search.facets.each do |item|
with(item).all_of( params[item].try(:split, "-") ) if params[item].present?
end
end
paginate(:page => params[:page], :per_page => 10)
end
Again, I appreciate the help. Definitely a noob, but really enjoying the process of building this site. Stackoverflow has been a HUGE help for me already, so I owe everybody who posts answers on here a big-time thank you.
I needed the answer to this myself, and seeing as there seems to be nothing else on the web about it, I decided I'd try to figure it out myself.
First I came to the conclusion through logic, that the controller can handle multiple facets and there's no reasons it cannot, I remembered that the best part about ruby is that it is the most human readable code, try to read your first controller and you'll see that it makes sense that it works. I tested this by manually entering in a query string in url, which returned expected results. Therefore, once I figured that out, I knew the issue resided in my view (which made me facepalm because it's fairly obvious now)
Your example is significantly more complex than mine, and my answer might not 100% meet every requirement but I'm pretty sure it's close. Also your code in your model regarding "departmental" etc is a little redundant in my view
Controller
def index
#search = Style.search do
fulltext params[:search]
facet :departmental, :seasonal, :classifier
with(:departmental, params[:department]) if params[:department].present?
with(:classifier, params[:classification]) if params[:classification].present?
with(:seasonal, params[:season]) if params[:season].present?
end
View
%h4 Departments
%ul
- for row in #search.facet(:departmental).rows
%li
- if params[:department].blank?
= link_to row.value, styles_path(
:department => row.value,
:classification => (params[:classification] unless params[:season].blank?),
:season => (params[:season] unless params[:season].blank?))
(#{row.count})
- else
%strong= row.value
= link_to "remove", styles_path(
:department => nil,
:classification => (params[:classification] unless params[:season].blank?),
:season => (params[:season] unless params[:season].blank?))
I am starting to learn Ajax with rails.
I have a catalog index page with a text_field_tag querying db if it finds similar "section" results.
Index.html.erb
<h1>Catalogs</h1>
<label>Search by Section:</label>
<%=text_field_tag :section %>
<%= observe_field(:section,
:frequency=> 0.1,
:update=> "article_list",
:url=>{ :action => :get_article_list }) %>
<div id="article_list"></div>
Catalogs_controller.rb
def index
end
def get_article_list
#section = request.raw_post.split(/&/).first
#catalogList = "<ol>"
Catalog.find(:all, :conditions => ["section = ?", #section]).each do |catalog|
#catalogList += "<li>" + catalog.title + "</li>"
end
#catalogList += "</ol>"
render :text => #catalogList
end
Question:
request.raw_post renders something like:
xml&authenticity_token=tgtxV3knlPvrJqT9qazs4BIcKYeFy2hGDIrQxVUTvFM%3D
so I use
request.raw_post.split(/&/).first
to get the section query ("xml"). It works, however how can I do if the query have a whitespace. (like "Open Source") In fact, I have Open Source sections in my db, but request.raw_post.split(/&/).first renders Open%20Source. How can I manage this? Did I have to use a full text search engine to achieve it or there is another way?
Thanks a lot for your explanation!
Look over your logs, in them you will see the post and the params being passed. You should not need to do your own query-string splitting. You should be able to use params[:section] to get the post data.
As your comment implies, there's something missing. Your observe_field needs to tell the Rails helper what to do. Check out: http://apidock.com/rails/ActionView/Helpers/PrototypeHelper/observe_field. Anyhow, you'll want to do something like:
observe_field(... # lots of parameters
:with => 'section'
)
And that should give you params[:section].
