searching from the main page in Rails - ruby-on-rails

I am working on my first web and Rails app and can not figure out how to get a search feature work from my main page to one of the controllers.
How to send the request and redirect to a results page to show the results from the search.
I can't get this to work as am not sure how to route in a way my variable #histories will keep results and display on the show page.
I would appreciate some insight into search from any page and displaying results on a dedicated page.
Here is what i have so far in terms of the controller, model and partials.
Shipments Model:
def self.search(search)
search_condition = search
find_by_sql("SELECT cargo_transit_histories.current_location,cargo_transit_histories.updated_at FROM cargo_transit_histories
INNER JOIN shipments ON shipments.id = cargo_transit_histories.shipment_id WHERE shipments.tracking_number='search_condition'")
end
Tracking Controller:
def search
#histories = Shipment.search(params[:search])
render('show')
end
Show (Found in Tracking view):
<div class="search_result">
<%= render 'track/search_results' %>
</div>
_search (partial):
<%= form_tag :controller => 'tracking', :action => 'search', :method => 'get' do %>
<%= text_field_tag :search, params[:search], :id => 'search_field' %>
<%= submit_tag "Search", :name => nil %>
<%= link_to_function "Clear", "$('search_field').clear()" %>
<% end %>
_search_results (partial):
<div class="Results list">
<table class="Resultslisting" summary="Result list">
<tr class="header">
<th>Current Location</th>
<th>Date/Time</th>
</tr>
<% if !#histories.empty? %>
<% #histories.each do |result| %>
<tr>
<td><%= result.current_location %></td>
<td><%= result.updated_at %></td>
</tr>
<% end %>
</table>
<% else %>
<p> The tracking number does not exist!</p>
<% end %>
</div>

Try something like the following adapted example:

But you need to dig a bit deeper into Rails 3 to understand why.

how can i get project_id by remarks in ruby on rails

I have manager remark model that takes input as a remark and decision value and saves it with the project site ID. I have a project site model that takes input as name, date, and file and stores it. Many remarks have a many to one relation with project site ID, and the project site belongs to the manager remark. I want to access the decision attribute boolean value in project site index form, but I am unable to access that boolean value in the index page of the project site. Here is my code of project site and manager remarks model, view and controller-
project site index.html.erb
<table>
<thead>
<tr>
<th>Name</th>
<th>Date</th>
<th>Attendance</th>
<th>Status</th>
<th colspan="3"></th>
</tr>
</thead>
<tbody>
<% #project_sites.each do |project_site| %>
<tr>
<td><%= project_site.name.titleize %></td>
<td><%= project_site.date %></td>
<td><%= link_to ' View attendance', project_site.file, :class => "fi-page-export-csv" %></td>
<td><%= "here i want to access manager remark decision value" %></td>
<td><%= link_to 'Remark ', project_site %><span>(<%= project_site.manager_remarks.size %>)</span></td>
<td><%= link_to 'Edit', edit_project_site_path(project_site) %></td>
<td><%= link_to 'Destroy', project_site, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</tbody>
project site controller
def index
#project_sites = ProjectSite.all.order("created_at DESC")
#manager_remark = ManagerRemark.joins(:project_site).where(:project_sites => { :user_id => #user.id })
end
# GET /project_sites/1
# GET /project_sites/1.json
def show
#manager_remark = ManagerRemark.new
#manager_remark.project_site_id = #project_site.id
end
# GET /project_sites/new
def new
#project_site = ProjectSite.new
end
def project_site_params
params.require(:project_site).permit(:name, :date, :file)
end
manager_remark controller
class ManagerRemarksController < ApplicationController
def create
#manager_remark = ManagerRemark.new(remark_params)
#manager_remark.project_site_id = params[:project_site_id]
#manager_remark.save
redirect_to project_site_path(#manager_remark.project_site)
end
def remark_params
params.require(:manager_remark).permit(:remark, :decision)
end
end
manager_remark view form
<%= form_for [ #project_site, #manager_remark ] do |f| %>
<div class="row">
<div class="medium-6 columns">
<%= f.radio_button :decision, true %>
<%= f.label :approve %>
<%= f.radio_button :decision, false %>
<%= f.label :reject %>
</div>
<br>
<br>
<div class="medium-6 cloumns">
<%= f.label :remark %><br/>
<%= f.text_area :remark %>
</div>

</div>
<% end %>
routes.rb
Rails.application.routes.draw do
root to: 'home#index'
devise_for :users
resources :project_sites do
resources :manager_remarks
end
get '/project_manager_level_two' => 'project_manager_level_two#index'
get '/project_managers' => 'project_managers#index'
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end
If I understand correctly, you have a ProjectSite that contains a ManagerRemark with a decision, right? If that's the case, the simple answer is:
<%= project_site.ManagerRemark.decision %>
If you are saying that each ProjectSite has many ManagerRemarks, you'll want to place the above inside a loop, like so:
<% project_site.manager_remarks.each do |manager_remark| %>
<%= manager_remark.decision %><br/>
<% end %>
This assumes that your models are correctly configured to recognize these relationships. The above may also be optimized by adding an include clause to your fetch inside the controller and there's no need to fetch the ManagerRemark objects separately. Therefore, you'd probably want something like:
def index
#project_sites = ProjectSite.all.includes( :manager_remark ).order("created_at DESC")
end

Custom Controller Method, Route, & ERB

I have a search form and I need to be able to filter based on whether or not pets are allowed, but I'm not sure how to accomplish this. I have setup a route, a controller method, and a button but none of that seems to be working.
listings_controller:
def pets_allowed
#listings = #listings.where(pets: true)
end
routes.rb:
get "pets_allowed" => "listings#pets_allowed"
html.erb file:
<div>
<%= link_to 'Pets Allowed', pets_allowed_path, :class => 'button btn-transparent' %>
</div>
Maybe you meant
def pets_allowed
#listings = Listing.where(pets: true)
end
This is a basic example of another way to do what I think you're aiming for (as per comments).
This adds a new action in your Listings controller that returns a filtered list of results based on the users input from the search form on your listings index page. The results are rendered using the same index template. The logic for checking/retrieving results can be modified based on what you want. If you just want a check box, only have a checkbox or a button that calls the action.
You could do similar logic but use ajax to return the results and render them on the index template using a partial.
This should give you enough information to google for examples/tutorials and try different ways of getting what you want.
Add a route:
# routes.rb
get 'pets_allowed', to: 'things#pets_allowed'
Add a new action:
# listings_controller.rb
# GET /things
# GET /things.json
def index
#listings = Listing.all
end
# Get /pets_allowed
def pets_allowed
#listings = Listing.where("name LIKE ? and pets = ?", "%#{params[:name]}%", params[:pets] )
render template: "listings/index", variable: #listings
end
Add a search form to your view:
# listings/index.html.erb
<h1>Listings</h1>
<%= form_tag('pets_allowed', method: 'GET' ) do %>
<%= label_tag :name %><br>
<%= text_field_tag :name %>
<br>
<%= label_tag :pets %><br>
<%= check_box_tag :pets, 't' %>
<br>
<%= submit_tag("Search") %>
<% end %>
<table>
<thead>
<tr>
<th>Listing name</th>
</tr>
</thead>
<tbody>
<% #listings.each do |listing| %>
<tr>
<td><%= listing.name %></td>
</tr>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Listing', new_listing_path %>

How do I add a delete function in my cart in rails?

the cart controller - im having trouble declaring the delete function
class CartController < ApplicationController
def add
id = params[:id]
cart = session[:cart] ||= {}
cart[id] = (cart[id] || 0) + 1
redirect_to :action => :index
end
def index
#cart = session[:cart] || {}
end
end
the main item page - the link to delete the item is already defined, I'm confused in the controller part
<h1 id="prodhead">Products</h1>
<table class="catalog">
<% for item in #items %>
<tr>
<td>
<div class="image">
<%= link_to (image_tag item.image_url), item %>
</div>
</td>
<td>
<div class="title">
<%= link_to item.title, item %>
</div>
<div class="description">
<%=h item.description %>
</div>
<div class="links">
<% if session[:login] == 1 %>
<%= link_to 'Edit Item', edit_item_path(item) %> |
***<%= link_to 'Delete Item', item, :confirm => 'Are you sure?', :method => :delete %>***
<% else %>
<%= link_to "Add to Cart", :controller => :cart, :action => :add, :id => item %><br />
<% end %>
</div>
<div class="price">
<%= number_to_currency(item.price, :unit => "&dollar;") %>
</div>
</td>
</tr>
<% end %>
</table>
<% if session[:login] == 1 %>
<p><%= link_to 'New item', new_item_path %></p>
<% end %>
The Routes.rb - the route for deleting is also defined already
OnlineShop::Application.routes.draw do
get "cart/index"
get "cart/add"
get "cart/checkout"
get "cart/del"
get "site/about"
get "site/contact"
get "user/admin_login"
get "user/logout"
resources :items
Well first of all I've notice you reposted your issue however this time somewhat more descriptive, please for future issues, think before you create a ticket and take the time to edit previous tickets which need refining to keep the community clean.
OT:
I see you've created item and cart resources with basic CRUD functionality however the way you did it is not quite "The rails way" I suggest you start a project bij using the scaffold command to learn how this CRUD and routes should be implemented.
If you are willing to learn more about the topic I advice reading: http://guides.rubyonrails.org/getting_started.html
Also I've noticed you use the "h" syntax to escape your output this is only done before Rails 2.3.8 may I suggest using a newer rails version when starting out?

How to create multi checkboxes and attach them to controller action like Edit or Delete?

I have created a scaffold Phone and index.html.erb shows a simple table with list of phone and edit/delete options. Now i want to add jquery checkboxes so I can do bulk delete or move actions. See attached image here
Can someone give me any idea/pointers on how to do it ?
Edit - this is the index.html.erb file
<% #phones.each do |phone| %>
<tr>
<td><%= phone.model %></td -->
<td><%= phone.type %></td>
</tr>
<% end %>
there is no form here so I am not sure I can use form_tag helpers or am I confusing something ?
Thanks
This would be a starting point, a form with the check boxes.
<%= form_tag(:controller => "phone", :action => "bulk_update", :method => "PUT") %>
<%= check_box_tag(:blackberry) %>
<%= label_tag(:pet_dog, "Blackberry") %>
<%= check_box_tag(:Nokia) %>
<%= label_tag(:pet_cat, "Nokia") %>
<%= submit_tag("Update") %>
<% end %>
Then a controller action called bulk_update and you could delete/update the records based on what has been submitted.
EDIT: You will also want to create a route in routes.rb for this.
Wrap the table in a form helper.
<%= form_tag foo_path do %>
# ...
<% #phones.each do |phone| %>
<tr>
<td><%= check_box_tag "selected[]", phone.id %></td>
<td><%= phone.model %></td>
<td><%= phone.type %></td>
</tr>
<% end %>
# ...
<%= button_tag "Do something" %>
<% end %>
This creates a form, with a checkbox in every row of the table. Replace foo_path with the route helper that you want to use. The value of the selected checkboxes will be passed to your controller action in the array params[:selected], where you can do with them as you wish. The values of each checkbox will be the id for the corresponding phone object.

How do I create 'remove tag' links with Acts_As_Taggable_On in Rails?

I'm creating a simple project tagging application using the Act_As_Taggable_On gem.
Adding projects, and adding tags (in my case 'types' / 'type_list') to each project works great. Where I'm stuck is how to remove individual tags using Act_As_Taggable_On. What I would like is to be able to click the 'x' text link next to each tag (see link) to remove the tag from that projects type_list.
I've searched the documentation and found a method along the lines of:
project.type_list.remove("your tag")
But what I need help with is how to call the remove method on the specific tag, especially since the whole thing is being iterated with .each do
My controller and model code is pretty minimal and standard - based on Act_As_Taggable_On docs. Here is my view code for generating the layout above:
<h1><%= #title %></h1>
<div class="column-left">
<% #projects.each do |project| %>
<div class="p_wrapper">
<table>
<tr>
<td><div class="project p_name"><%= project.name %></div></td>
<td><div class="p_link"><%= link_to 'Edit', edit_project_path(project) %></div></td>
<td><div class="p_link"><%= link_to 'Nuke', project, :confirm => 'Are you sure?', :method => :delete %></div></td>
</tr>
</table>
<table>
<tr>
<td>
<% project.type_list.each do |tag|%>
<div class="p_tag">
<%= tag %>
<%= link_to "x", # %> <!-- THIS IS THE PART I'M STUCK ON -->
</div>
<% end %>
</td>
</tr>
</table>
<table>
<tr>
<td>
<%= form_for(project) do |f| %>
<%= f.text_field :inject_tags %>
<%= f.submit "Add Tag" %>
<% end %>
</td>
</tr>
</table>
</div>
<% end %>
<br />
<%= link_to 'Add new project', new_project_path %>
</div>
Can anyone point me in the right direction? Am I implementing this correctly to be able to actually remove tags as described?
Thanks guys!
I would simply add a new method to your projects controller, like so:
def remove_tag
Project.find(params[:id]).type_list.remove(params[:tag])
end
And in your routes file
resources :projects do
member do
put 'remove_tag', :as => :remove_tag
end
end
And in your view
<%= link_to 'x', remove_tag_project_path(project), :tag => tag, :method => :put %>
Of course you should add some sanitation, but it should work this way...
Based on #Vapire's suggested code - finally worked out a working solution. Just some minor edits to the view, route, and controller. Let me know if you see anything dodgy in here - still trying to get a good grasp of Ruby/Rails so all suggestions/refactoring ideas welcome.
The updated test site is at project-list.heroku.com.
Updated projects controller to find current project, remove :tag passed from index view through route:
def remove_tag
#project = Project.find(params[:id])
#project.type_list.remove(params[:tag])
#project.save
redirect_to projects_path, :flash => { :success => "Updated - tag nuked."}
end
Updated route:
resources :projects
match 'projects/:id/remove_tag/:tag' => 'projects#remove_tag'
Updated the link_to 'x' code to pass :tag params through the updated route above:
<% project.type_list.each do |tag|%>
<div class="p_tag">
<%= tag %>
<%= link_to 'x', {:action => "remove_tag", :id => project.id, :tag => tag,
:controller => "projects"} %>
</div>
<% end %>
This is obviously new ground for me so would appreciate if you have a different / better way of handling this issue please let me know! Also, thanks for your help #Vapire!
