I am trying to display a message using foundation framework to validate and add email address.The validation happens as expected, but no messages get displayed. Is there something I am missing?
_messages.html.erb
<% flash.each do |name, msg| %>
<% if msg.is_a?(String) %>
<div data-alert class="alert-box round <%= name.to_s == :notice ? "success" : "alert" %>">
<%= content_tag :div, msg %>
×
</div>
<% end %>
<% end %>
contacts_controller.rb
class ContactsController < ApplicationController
def new
#contact = Contact.new
end
def create
#contact = Contact.new(secure_params)
if #contact.valid?
#contact.update_spreadsheet
flash[:notice] = 'You have been added'
redirect_to root_path
else
flash.now[:alert] = 'Not a valid email'
redirect_to root_path
end
end
private
def secure_params
params.require(:contact).permit(:email)
end
end
application.html.erb
<header>
<%= render 'layouts/navigation' %>
</header>
<%= render 'layouts/messages' %>
<%= yield %>
</body>
</html>
Within messages partial _messages.html.erb, you are comparing a string to a symbol which is the reason the message is not displayed.
name.to_s is an object of String class and
:notice is an object of Symbol class
Problem line:
<div data-alert class="alert-box round <%= name.to_s == :notice ? "success" : "alert" %>">
You should match name.to_s == "notice" here
The issue was indeed with the _messages partial
changed
<div data-alert class="alert-box round <%= name.to_s == :notice ? "success" : "alert" %>">
to
<div data-alert class="alert-box round <%= name.to_s == 'notice' ? 'success' : 'alert' %>">
and all worked as expected.

I'm newbee in rails, so could you explain why method survey_type works for this (attempts/new):
<h2 class="survey-title">
<%= #survey.name %>
<p><small><%= #attempt.survey.description %></small></p>
</h2>
<%= form_for(#attempt, url: attempt_scope(#attempt)) do |f| %>

<%= f.fields_for :answers, get_answer_fields(#attempt) do |answer_fields| %>

<% question = answer_fields.object.question %>
<p class="question"><%= question.text %></p>
<ul class="options">
<%= collection_check_boxes('survey_attempt[answers_attributes]', question.id, question.options, :id, :text) do |b| %>

Thanks in advance!
In your AttemptsController you have
before_filter :load_survey, only: [:new, :create]
that sets the #survey variable for your new action, but doesn't get called for show, so that action never gets the variable set.
You can add :show into your :only conditions
before_filter :load_survey, only: [:new, :create, :show]
and that should fix things
I have an Item Model. Its for a retail store.
When im on an item view. Lets say for item id 11. Then i click on edit button. I receive the following error
Anyone have any clues? Any help would be greatly appreciated.
NoMethodError in Items#edit
undefined method `errors' for nil:NilClas
<% if #user.errors.any? %>
<div id="error_explanation">
<div class="alert alert-danger">
The form contains <%= pluralize(#user.errors.count, "error") %>.
</div>
<ul>
Below is where my edit button is in Item View
<!-- right column -->
<div class="col-lg-6 col-md-6 col-sm-5">
<div class = "itemtitle"><%= #item.title %> </div>
<div class = "price">$<%= #item.price %> </div>
<%= link_to "Edit Items", edit_item_path(#item) %>
<div class="productFilter productFilterLook2">
<div class="filterBox">
<select>
<option value="strawberries" selected>Quantity</option>
</select>
</div>
Here is my Items controller.

#items = Item.paginate(page: params[:page])
end

#item = Item.new

You don't define #user in your edit action.
Probably somewhere in the template you render for the edit action you ask for #user.errors.any?. Either disable this part or modify to something like #item.errors.any? etc.
I have a issue.I want to fetch data from data base according to text field value.This text field will take two types of value.First one is simple number(e.g-123456789) and second one is like this(e.g-123456789/1).The simple number is present in DB for one table.In the second one number after "/" (i.e-1) is another table's id which is associated with first table.Then my aim is when user will give the input "123456789" the data will fetch according to this number by searching and when user will give the input "123456789/1" first it will split the number and values will be fetched according to both number and id (i.e-123456789 and 1) from the both table.
Here i am explaining some of my code below.

Here i have done for simple number please help me to fetch data from both table by the second input number(i.e-123456789/1).For this all operations are executing inside "scan_hcsy" method.Atleast help me to split the number(i.e-123456789/1) to 123456789 and 1 so that i can fetch data according to this number and id.
You can split the string, which results into an Array:
"12345678/1".split('/')
=> ["12345678", "1"]
In your case:
splitted = params[:hcsy][:reciept].split('/')
hcys = splitted[0]
table_id = splitted[1]

Try renaming your file to create.js.coffee.
It should still render erb although it is not written in the file extension.

Rails 3.1.3
I am making a simple site where people can share short stories and can rate those stories on a 5 Star rating system. The Star rating system is the problem. I can get it to work fine in the stories/show.html view, but not on the indexed home page. Here is my code:
home.html.erb
<% content_for(:scripts) do %>
<%= javascript_include_tag 'rating_ballot'%>
<% end %>
<div id="talesFeedHome">
<p class="notice"><%= notice %></p>
<%= render #tales.sort_by { |tale| tale.created_at }.reverse %>
</div>
<p class="clear"> </p>
tales/_tale.html.erb
<% if signed_in? %>
<div id="homeTales">
<ul>
<div id="taleShow">
<div id="controlPanel">
<li id="taleUserName"><%= tale.user.name %></li>
<li id="averageRating"> Your Rating:<br /><%= render "tales/stars" %></li>
</div>
<div id="taleDisplay">
<li><%= link_to(tale) do %>
<span><%= tale.title %> </span>
<span><%= tale.content %></span>
<% end %>
</li> <br />
</div>
</div>
</ul>
</div>
<% else %>
...
tales/_stars.html.erb
<div id="starRating">
<%= form_for(rating_ballot, :remote => true, :html => { :class => 'rating_ballot' }) do |f| %>
<%= f.label("value_1", content_tag(:span, '1'), {:class=>"rating", :id=>"1"}) %>
<%= radio_button_tag("rating[value]", 1, current_user_rating == 1, :class => 'rating_button') %>
<%= f.label("value_2", content_tag(:span, '2'), {:class=>"rating", :id=>"2"}) %>
<%= radio_button_tag("rating[value]", 2, current_user_rating == 2, :class => 'rating_button') %>
<%= f.label("value_3", content_tag(:span, '3'), {:class=>"rating", :id=>"3"}) %>
<%= radio_button_tag("rating[value]", 3, current_user_rating == 3, :class => 'rating_button') %>
<%= f.label("value_4", content_tag(:span, '4'), {:class=>"rating", :id=>"4"}) %>
<%= radio_button_tag("rating[value]", 4, current_user_rating == 4, :class => 'rating_button') %>
<%= f.label("value_5", content_tag(:span, '5'), {:class=>"rating", :id=>"5"}) %>
<%= radio_button_tag("rating[value]", 5, current_user_rating == 5, :class => 'rating_button') %>
<%= hidden_field_tag(:tale_id, #tale.id) %>
<% end %>
</div>
It is at this point, in the hidden field tag, that I get this error:
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
Here are the 3 relevant controllers:
pages_controller.rb
class PagesController < ApplicationController
def home
#tales = Tale.all
end
end
tales_controller.rb
class TalesController < ApplicationController
respond_to :html, :js
def new
#tale = Tale.new
end
def show
#tale = Tale.find(params[:id])
end
def index
#tales = Tale.all
#tale = Tale.find(params[:id])
end
...
ratings_controller.rb
class RatingsController < ApplicationController
before_filter :authenticate_user!
respond_to :html, :js
def create
#tale = Tale.find_by_id(params[:tale_id])
#rating = Rating.new(params[:rating])
#rating.tale_id = #tale.id
#rating.user_id = current_user.id
if #rating.save
respond_to do |format|
format.html { redirect_to #tale, :notice => "Your rating has been saved" }
format.js
end
end
end
def update
#rating = current_user.ratings.find_by_tale_id(params[:tale_id])
#tale = #rating.tale
if #tale and #rating.update_attributes(params[:rating])
respond_to do |format|
format.html { redirect_to #tale, :notice => "Your rating has been updated" }
format.js
end
end
end
end
The problem is here somewhere. Somehow when rendering #tales on the home page, this invalidates the #tale.id on the _stars partial. I can not figure out how to solve this. Thank You.
ok, I think your value of #tales is nil so please do the following things and let me know what would be the result
first put raise #tales.Inspect in your home method in your PagesController
second <%= raise tale.inspect%> in _tale.html.erb.
want to check weather value of tale is null or not.
