I've been trying to install and use the new sync realtime partials gem, but when it comes to putting the code in my views it all goes wrong.
This is my existing code, pre sync.
<%= render :partial => "tasks/table", :locals => { :assigned_to => true, :user_dashboard => false } %>
It now reads:
<%= sync partial: 'task_table', resource: #tasks %>
I've created a sync folder in my views, and a tasks folder, and added in _task_table.html.erb.
NoMethodError in Tasks#index
Showing /Users/callum/rails_projects/arc_app/app/views/tasks/index.html.erb where line #17 >raised:
undefined method model_name for WillPaginate::Collection:Class
In my tasks_controller.rb i have
def index
#tasks = Task.search(params[:search]).order(sort_column + " " + sort_direction).paginate(:per_page => 15, :page => > params[:page]).find_by_status(params[:status])
end
I'm quite new to rails but, I'm guessing its to do with the #tasks in my controller, I also process the table partial from a different controller with the same / similar error.
Use the following way and don't mix up all together:
def index
user_task = case params[:status].present?
when true then Task.where(:status => params[:status]).all
else Task
end
#tasks = user_task.paginate(:per_page => 15, :page => params[:page]).search(params[:search])
end

I was just trying out the Elastic Search in my Rails app replacing the existing search function. Everything worked nicely but I am getting http://localhost:3000/contents/video/%23%3CElasticsearch::Model::Response::Result:0x007fe24e118f40%3E url.
in content.rb
def to_param
"#{id}/#{title.parameterize}.html"
#"#{id}-#{title.downcase.slice(0..30).gsub(/[^a-z0-9]+/i, '-')}.html"
end
and in search action
def search
if params[:q].nil?
#indexs = []
else
#indexs = Content.search params[:q]
end
and in views
<% #indexs.each do |f|%>
<%= link_to((truncate f.title, length: 60), {:controller => "contents", :action => "weblinks", :id => f.to_param}, target: "_blank") %>
<% end %>
It works fine for the default listing page, but its URL generating error in search result page. Please help,and also how to replace the {:controller => "contents", :action => "weblinks", :id => f.to_param} with weblinks_path(:format) routes
I assume you use elasticsearch gem, if so you should use records to get ActiveRecord models #indexs.records
I want to avoid some gems so I came up with this solution to search between multiple models.
But It seem to just work for first model that is listed.
SearchController :
def index
#products = Product.search(params[:search]).paginate(:per_page => 5, :page => params[:page])
#manufacturer_name = Manufacturer.search(params[:search]).paginate(:per_page => 5, :page => params[:page])
#category_name = Category.search(params[:search]).paginate(:per_page => 5, :page => params[:page])
end
Inside my 3 models I have like this:
def self.search(search)
if search
where('name LIKE ? ', "%#{search}%")
else
scoped
end
Search#index
<%if #products.present?%>
<%= render partial: "products/found" %>
<%end%>
<%if #manufacturer_name.present?%>
<%= render partial: "products/foundmanufacturers" %>
<%end%>
<%if #category_name.present?%>
<%= render partial: "products/foundmanufacturers" %>
<%end%>
I prepared for each model seperated partial.
But when I search for name that definetely should be in all categories. But there is no results found, only when I run search for products name. Then I get results I want.
Any tip would be great. Tnx
it's just refactoring create name scope like as shown below
scope :by_name,lambda{|name| where("name like (?)","%#{name}%") if name.present?}
# In controller
Product.by_name(params[:search]).paginate(:per_page => 5, :page => params[:page])
no need of search method in model it's better to write scope unless you are doing some complex checking,
Second try to see in console wether you are getting results based on your search params?
I'm reworking a Rails 2 website. Right now, I'm getting an error, and I think it's because a value is being submitted as blank instead of .nil. However, my attempts to keep it nil don't seem to be working. I appreciate any help you have to offer.
From Model, based on Make blank params[] nil
NULL_ATTRS = %w( start_masterlocation_id )
before_save :nil_if_blank
protected
def nil_if_blank
NULL_ATTRS.each { |attr| self[attr] = nil if self[attr].blank? }
end
View
I've got jQuery that adds a value to this hidden field when a start_masterlocation_id exists. I've also got jQuery that removes the field attribute when it does not exist.
<%= hidden_field :newsavedmap, :start_masterlocation_id, :id => "start-masterlocation-id-field" %>
Finally, here is the part of the controller that is throwing the error. This is the controller for the page that holds the form (Maptry), not the controller for Newsavedmap. I think I have to delete the #newsavedmap.id, #newsavedmap.mapname, and #newsavedmap.optimize lines now that I'm going with form handlers, but I don't think that's related to this error.
Controller
def maptry
#itinerary = Itinerary.find(params[:id])
if #itinerary.user_id == current_user.id
respond_to do |format|
#masterlocation = Masterlocation.find(:all)
format.html do
end
format.xml { render :xml => #masterlocation }
format.js do
#masterlocation = Masterlocation.find(:all)
render :json => #masterlocation.to_json(:only => [:id, :nickname, :latitude, :longitude])
end
end
if params[:newsavedmap_id]
#newsavedmap = Newsavedmap.find(:first, :conditions => {:id => params[:newsavedmap_id]})
#waypoint = Waypoint.find(:all, :conditions => {:newsavedmap_id => params[:newsavedmap_id]})
#newsavedmap.id = params[:newsavedmap_id]
#newsavedmap.mapname = Newsavedmap.find(:first, :conditions => {:id => params[:newsavedmap_id]}).mapname
#newsavedmap.optimize = Newsavedmap.find(:first, :conditions => {:id => params[:newsavedmap_id]}).optimize
if !#newsavedmap.start_masterlocation_id.nil?
#start_name = Masterlocation.find(:first, :conditions => {:id => #newsavedmap.start_masterlocation_id}).name
end
if !#newsavedmap.end_masterlocation_id.nil?
#end_name = Masterlocation.find(:first, :conditions => {:id => #newsavedmap.end_masterlocation_id}).name
end
else
#newsavedmap = Newsavedmap.new
end
else
redirect_to '/'
end
end
Error
This does not occur when a start_masterlocation_id is present in the database.
undefined method `name' for nil:NilClass
I solved this by ignoring the nil problem. Instead, I used
!#newsavedmap.start_masterlocation_id.blank?
This evaluates whether the data in the record is blank and then either does or doesn't do something. Obviously, this results in unwanted "blank" data being left inside my database, so it's not ideal, but it helped me move forward with the project. I'd appreciate any responses that deal directly with the nil issue and tell me how to have Rails ignore blank data in a form.
I'm hoping this is a simple question - I have the following helper code:
module ApplicationHelper
def add_feature_fields(feature_types, object_form_builder, actions_visible)
feature_types.length.times {object_form_builder.object.features.build}
i = 0
fields = object_form_builder.fields_for :features do |features_builder|
render :partial => "features/fixed_feature", :locals => {:feature => features_builder, :fixed_feature_type => feature_types[i], :form_actions_visible => actions_visible}
i = i + 1
end
end
end
The code is working as expected, except for the line i = i + 1. For some reason, this seems to be breaking the loop, and nothing is rendered. Evidently, I am doing this wrong somehow - perhaps fields_for is not a normal loop?
How can I increment i by 1 each time the loop runs?
I'm not sure about the below code, but something around this should work and fix the issue. Give a try
object_form_builder.each.with_index do |builder,index|
object_form_builder.fields_for :features, builder do |feature_builder|
render :partial => "features/fixed_feature", :locals => {:feature => features_builder, :fixed_feature_type => feature_types[i], :form_actions_visible => actions_visible}
end
end
I was able to get this working by doing the following:
module ApplicationHelper
def add_feature_fields(feature_types, object_form_builder, actions_visible)
feature_types.length.times {object_form_builder.object.features.build}
i = -1
object_form_builder.fields_for :features do |features_builder|
i = i + 1
render :partial => "features/fixed_feature", :locals => {:feature => features_builder, :fixed_feature_type => feature_types[i], :form_actions_visible => actions_visible}
end
end
end
I believe what was happening was that when I did i = i + 1 after I called render, the return value was the iterator and not render (since the method returns the last value).
I want to display different types of objects in the same ajax called controller function. I want to render out when I send back an ajax call. The problem is I want the "title" attribute of one object and the "name" attribute of another object. I can't render 2 partials and can seem to figure out how to check the type of object an object is. How do I solve this problem?
Here is my current controller setup (NOT CORRECT)
#objects = Obj.find(:all,:conditions => ["name Like ?", "#{prefix}%"])
#moreObjects = ObjTwo.find(:all,:conditions => ["title Like ?","#{prefix}%"])
if #objects.empty?
render :text => "No Matches"
else
render :partial => 'one', :collection => #objects
end
if #moreObjects.empty?
render :text => "No Matches"
else
render :partial => 'two', :collection => #moreObjects
end
try something like
<%= obj.title if obj.respond_to?(:title) %>
Here's one option that doesn't involve checking its type - in your Obj and ObjTwo classes add a new method:
def fancy_pants
title
end
def fancy_pants
name
end
Then you can combine #objects and #moreObjects - you'll only need one if statement and one partial.
#search_domination = #objects + #moreObjects
if #search_domination.empty?
render :text => "No Matches"
else
render :partial => 'one', :collection => #search_domination
end
You could use Object.is_a? but that's not a very clean solution. You could also try mapping your data before presentation to help keep your views lightweight.
