I have this on my view:
<div class='container'>
<div class='row upper_container'>
<div class='search_container'>
<%= form_tag deals_path, :method => :get, :class => 'navbar-form navbar-left' do %>
<div class='form-group'>
<%= text_field_tag :search, params[:search], class: 'form-control' %>
</div>
<%= submit_tag 'Search', :name => nil %>
<% end %>
</div>
</div>
<% #deals.each_with_index do |d, i| %>
<% if i % 3 == 0 %>
<div class='row middle_container'>
<% end %>
<div class='col-md-4'>
<div class='deal_container'>
<%= d.title %>
<img src='<%= d.photo %>', class='deal_img'>
</div>
</div>
<% if (i % 3 == 2) || (i == (#deals.length - 1)) %>
</div>
<% end %>
<% end %>
</div>
this in my controller:
class DealsController < ApplicationController
def index
# #deals = Deal.paginate(:page => params[:page])
#search = Deal.search do
fulltext params[:search]
end
#deals = #search.result
end
private
def deal_params
params.require(:deal).permit(:title)
end
end
and this in my model:
class Deal < ActiveRecord::Base
searchable do
text :title
end
end
when I want to do a seach by some word, like 'Treatment', the #deals variable, in the controller is null, but the param is being sent: Parameters: {"utf8"=>"✓", "search"=>"Treatment"}
any idea?
Try this:
query = params[:search]
#search = Deal.search do
fulltext query
end
#deals = #search.result
Please check this answer for details.

Hello guys I searched everywhere on how to output form errors but no luck. I tried almost all the code I found on the internet but still didn't work.
Here are some of my files:
view/books/new.html.erb
<div class="container">
<h2>Create a new book</h2>
<%= form_with model: #book, url: create_new_book_path do |f| %>
<% if #book.errors.any? %>
<ul>
<% #book.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
<% end %>
<div class="form-group row">
<%= label_tag(:title, "Title:", class: "col-sm-2 col-form-label") %>
<div class="col-sm-10">
<%= f.text_field :title, class: "form-control" %>
</div>
</div>
<div class="form-group row">
<%= label_tag(:price, "Price:", class: "col-sm-2 col-form-label") %>
<div class="col-sm-10">
<%= f.text_field :price, class: "form-control" %>
</div>
</div>
<div class="form-group row">
<%= label_tag(:subject_id, "Subject:", class: "col-sm-2 col-form-label") %>
<div class="col-sm-10">

</div>
</div>
<div class="form-group row">
<%= label_tag(:description, "Book description:", class: "col-sm-2 col-form-label") %>
<div class="col-sm-10">
<%= f.text_area :description, class: "form-control" %>
</div>
</div>
<%= submit_tag "Create book", class: "btn btn-success" %>
<%= link_to "Cancel", books_path, class: "btn btn-danger" %>
<% end %>

<main role="main">
<%= yield %>
</main>
I don't really know what I'm missing to get the errors, grateful for your answers!!
try putting them in a flash like this and render it in your view
def create
#book = Book.new
if #book.update(book_params)
flash[:notice] = 'success'
redirect_to action: 'index'
else
flash[:alert] = #book.errors.full_messages.join(', ')
redirect_to action: 'index'
end
end
and in your view render those flashes like
<% if flash[:notice]%>
<span class='notice'><%= flash[:notice] %></span>
<% end %>
<% if flash[:alert]%>
<span class='alert'><%= flash[:alert] %></span>
<% end %>
View:

<%= select_tag(:sortway, options_for_select(["Order By Asc","Order By Desc"])) %>

</div>
Model:
if(params[:sortway]=="Order By Desc")
#books=#books.order(params[:sorttitle]: :desc)
else
#books=#books.order(params[:sorttitle]: :asc)
end
#books = #books.order(params[:sorttitle] => :desc)
i'm trying to show all the videos in my app so when i'm adding a new video and want to redirect to movie_path so i did this in my video controller:
def create
#video = Video.new(video_params)
if #video.save
flash[:success] = 'Video added!'
redirect_to movie_path(#movies)
else
render :new
end
end
it gives me an error:
undefined method `any?' for nil:NilClass
this is my show page that want to show the video:
<% if #videos.any? %>
<div class="container">
<div id="player-wrapper"></div>
<% #videos.in_groups_of(3) do |group| %>
<div class="row">
<% group.each do |video| %>
<% if video %>
<div class="col-md-4">
<div class="yt_video thumbnail">
<%= link_to image_tag("https://img.youtube.com/vi/#{video.uid}/mqdefault.jpg", alt: video.title,
class: 'img-rounded'),
"https://www.youtube.com/watch?v=#{video.uid}", target: '_blank' %>
<div class="caption">
<h5><%= video.title %></h5>
<p>Published at <%= video.published_at.strftime('%-d %B %Y %H:%M:%S') %></p>

this is movie controller:
def index
#movies = Movie.all.order(:cached_votes_score => :desc)
#movies = #movies.paginate(:page => 1, :per_page => 8)
end
def show
#reviews = Review.where(movie_id: #movie.id).order("created_at DESC")
end
def new
#movie = current_user.movies.build
#movie = Movie.new
#categories = Category.all.map{|c| [ c.name, c.id ] }
end
and this is the routes i have:
nil don't have method any? so you must protect your code against it
instead this line:
<% if #video.any? %>
write this:
<% if #video.try(:any?) %>
I think you have not defined #videos, you have defined #video, so you should try this:
<% if #video.any? %>
#orders should have multiple orders yet when using a respond_to to create an CSV, I only have one order record available in my cvs.erb file. Here's the code.
reports_controller.rb
def orders
params[:q] = {} unless params[:q]
if params[:q][:completed_at_gt].blank?

end
if params[:q] && !params[:q][:completed_at_lt].blank?
params[:q][:completed_at_lt] = Time.zone.parse(params[:q][:completed_at_lt]).end_of_day rescue ""
end
params[:q][:s] ||= "completed_at desc"
#search = Order.complete.ransack(params[:q])

I'm getting an undefined method 'each' for nil class in my create method for a join table that I have.

Here's the exact error I'm getting
I've so far been unable to figure out the problem. What am I missing?
Stupid error but didn't catch it until I posted the form code... Thanks for the help!!
"reflection[cause_ids][]"
should be
"pin[cause_ids][]"
Thanks again for the help:)
