RESTful pagination routes using will_paginate - ruby-on-rails

I have nested routes like this :
map.resources :foo do |foo|
foo.resources :bar do |bar|
bar.resources :baz
end
end
i have list with pagination in the index action for each resource, i need to caches each of this pages, to do so i need the routes to be RESTful, how do i implements REFTful routes for it?
for example i want the route will be like this :
http://www.example.com/foo/:id/pages/:page_number
http://www.example.com/foo/:id/bar/:id/pages/:page_number

create custom_link_renderer.rb in app/helpers/
class CustomLinkRenderer < WillPaginate::LinkRenderer
def page_link(page, text, attributes = {})
#template.link_to text, "#{#template.url_for(#url_params)}/pages/#{page}", attributes
end
end
add this line to config/environment.rb
WillPaginate::ViewHelpers.pagination_options[:renderer] = 'CustomLinkRenderer'

I had the same problem. I wrote my own LinkRenderer like this to fully use nested routes.
class PaginationListLinkRenderer < WillPaginate::ViewHelpers::LinkRenderer
protected
def page_number(page)
unless page == current_page
if !#options[:params][:url].to_s.empty?
tag(:li, link(page, #options[:params][:url] + "?page=" + page.to_s))
else
tag(:li, link(page, page, :rel => rel_value(page)))
end
else
tag(:li, page, :class => "current")
end
end
def previous_or_next_page(page, text, classname)
if page
if !#options[:params][:url].to_s.empty?
tag(:li, link(text, #options[:params][:url] + "?page=" + page.to_s, :class => classname))
else
tag(:li, link(text, page, :rel => rel_value(page), :class => classname))
end
#tag(:li, link(text, page), :class => classname)
else
tag(:li, text, :class => classname + ' disabled')
end
end
def html_container(html)
tag(:ul, html, container_attributes)
end
end
Then you have to call will_paginate with this parameters:
<%= will_paginate :params => { :url => project_task_lists_path(#project) }, :renderer => PaginationListLinkRenderer %>
I hope this helps :)

How to add a field into a snippet in Comfortable Mexican Sofa

I plan to use snippets in Comfortable Mexican Sofa to store email templates. But is there a way to add a field into a snippet. I would use it to store the subject of the email. Would be good to have also the subject in the cms so that our editors can change it if they feel like it.
By default snippets seem to have only two fields 'Label' and 'Identifier'. And of course the 'Content'. I would like to add also a 'Subject' String into the fields.
Simple Three Step Process:
1:
rails g migration AddSubjectToComfyCmsSnippets subject:string
2:
rake db:migrate
3:
create app/views/comfy/admin/cms/snippets/_form.html.haml with the following content:
- content_for :right_column do
= render 'comfy/admin/cms/files/index'
= render :partial => 'comfy/admin/cms/partials/snippet_form_before', :object => form
= form.text_field :label, :data => {:slugify => #snippet.new_record?}
= form.text_field :identifier, :data => {:slug => true}
= form.text_field :subject
= form.text_area :content, :data => {'cms-rich-text' => true}
= render :partial => 'comfy/admin/cms/categories/form', :object => form
= render :partial => 'comfy/admin/cms/partials/snippet_form_after', :object => form
= form.form_group :class => 'form-actions' do
= form.submit t(#snippet.new_record?? '.create' : '.update'), :class => 'btn btn-primary'
= link_to t('.cancel'), comfy_admin_cms_site_snippets_path, :class => 'btn btn-link'
Now you can reference the subject in your app like so:
Subject: #{#snippet.subject}
Monkey patch to get fixtures working:
create config/initializers/cms_monkey_patch.rb with the following contents:
ComfortableMexicanSofa::Fixture::Snippet::Importer.class_eval do
def import!
Dir["#{self.path}*/"].each do |path|
identifier = path.split('/').last
snippet = self.site.snippets.find_or_initialize_by(:identifier => identifier)
# setting attributes
categories = []
if File.exists?(attrs_path = File.join(path, 'attributes.yml'))
if fresh_fixture?(snippet, attrs_path)
attrs = get_attributes(attrs_path)
snippet.label = attrs['label']
snippet.subject = attrs['subject']
categories = attrs['categories']
end
end
# setting content
%w(html haml).each do |extension|
if File.exists?(content_path = File.join(path, "content.#{extension}"))
if fresh_fixture?(snippet, content_path)
snippet.content = extension == "html" ?
::File.open(content_path).read :
Haml::Engine.new(::File.open(content_path).read).render.rstrip
end
end
end
# saving
if snippet.changed? || self.force_import
if snippet.save
save_categorizations!(snippet, categories)
ComfortableMexicanSofa.logger.info("[FIXTURES] Imported Snippet \t #{snippet.identifier}")
else
ComfortableMexicanSofa.logger.warn("[FIXTURES] Failed to import Snippet \n#{snippet.errors.inspect}")
end
end
self.fixture_ids << snippet.id
end
# cleaning up
self.site.snippets.where('id NOT IN (?)', fixture_ids).each{ |s| s.destroy }
end
end
end
ComfortableMexicanSofa::Fixture::Snippet::Exporter.class_eval do
def export!
prepare_folder!(self.path)
self.site.snippets.each do |snippet|
snippet_path = File.join(self.path, snippet.identifier)
FileUtils.mkdir_p(snippet_path)
# writing attributes
open(File.join(snippet_path, 'attributes.yml'), 'w') do |f|
f.write({
'label' => snippet.label,
'subject' => snippet.subject,
'categories' => snippet.categories.map{|c| c.label}
}.to_yaml)
end
# writing content
open(File.join(snippet_path, 'content.html'), 'w') do |f|
f.write(snippet.content)
end
ComfortableMexicanSofa.logger.info("[FIXTURES] Exported Snippet \t #{snippet.identifier}")
end
end
end

Save array of data from one check_box_tag

I have view that created from сontributed API
=form_tag add_group_vk_vk_entries_path, method: :put do
-length_of_array = #vk_groups['message']['vk'].length
.row-fluid
-#vk_groups['message']['vk'][1..length_of_array].each do|item|
.span4
p= check_box_tag "vk_groups[]", item['gid']
p=item['name']
p=image_tag item['photo'], :size => "100x100",:class => "img-circle"
= submit_tag "ok"
I want to sent the data from this api to my controller by check_box_tag. I want to send not only item['gid'] i want to sent to my controller all data that i checked through one check_box_tag but i don't anderstand how.
In my controller
def add_group_vk
params[:vk_groups].each do |item|
if VkEntry.not_exists?(item) == true
VkEntry.create!(
:git => item
)
end
end
redirect_to vk_entries_url
end
i want something like this
def add_group_vk
params[:vk_groups].each do |item|
if VkEntry.not_exists?(item) == true
VkEntry.create!(
:git => item[:gid],
:name=> item[:name],
:ser=> item[:ser],
:photo=> item[:photo]
)
end
end
redirect_to vk_entries_url
end
First, I'm assuming that your above generates the check boxes with names like:
vk_groups[100], vk_groups[101],...
All you can really extract is a list of id's, they're in the the hash key, the value is not important.
params[:vk_groups] will yield a hash, iterate over the hash like so
def add_group_vk
params[:vk_groups].each do |key,val|
if VkEntry.not_exists?(key) == true
VkEntry.create!(
:git => key,
:name=> item[:name],
:ser=> item[:ser],
:photo=> item[:photo]
)
end
end
redirect_to vk_entries_url
end
As a result i done:
def add_group_vk
params[:vk_groups].each do |key,val|
item = eval val
if VkEntry.not_exists?(key) == true
VkEntry.create!(
:gid => key,
:name => item['name'],
:screen_name => item['screen_name'],
:is_closed => item['is_closed'],
:is_admin => item['is_admin'],
:is_member => item['is_member'],
:type_vk => item['type_vk'],
:photo => item['photo'],
:photo_medium => item['photo_medium'],
:photo_big => item['photo_big']
)
end
end
redirect_to vk_entries_url
end
In view
p= check_box_tag "vk_groups[#{item['gid']}]", item

how to redirect two different url's from two different buttons from index in controller?

How to redirect the two links to two urls by using single method in controller?
Example:
def index
#location_id = Location.find(#location_id)
#epc = Enr::Rds::CurrentEpc.find_by_location_id(#location_id)
if # PDF EPC link clicked
#epc.current_epc_path[-4..-1] == '.pdf'
content = open(#epc.current_epc_path, "rb") {|io| io.read }
send_data content, :filename => 'epc.pdf', :disposition => 'inline'
end
if # LIVE EPC link clicked
#epc = Enr::Rds::XmlData.find_by_location_id(#location_id)
redirect_to #epc.report_url
end
end
in my view,
<%= link_to 'PDF', enr_location_current_epc_index_path(#location) %>
<%= link_to 'LIVE', enr_location_current_epc_index_path(#location) %>
in my routes
resources :current_epc, only: [:index, :show] do
get :download, :on => :collection
end
I would consider create 2 differente actions. One for each case. It would make your actions and your code much easier to read.
Then u would result with 3 actions. Index which would only load the initial objects, one to treat the specific id by the first logic and another link to treat the second logic.
def index
#location_id = Location.find(#location_id)
#epc = Enr::Rds::CurrentEpc.find_by_location_id(#location_id)
end
pdf_epc
#location_id = Location.find(#location_id)
#epc = Enr::Rds::CurrentEpc.find_by_location_id(#location_id)
#epc.current_epc_path[-4..-1] == '.pdf'
content = open(#epc.current_epc_path, "rb") {|io| io.read }
send_data content, :filename => 'epc.pdf', :disposition => 'inline'
end
def live_epc
#epc = Enr::Rds::XmlData.find_by_location_id(#location_id)
redirect_to #epc.report_url
end
in your routes
resources :current_epc, only: [:index, :show] do
get :download, :on => :collection
end
get "/pdf_epc/:id" => "current_epc#pdf_epc", :as => enr_location_current_epc_pdf
get "/live_epc/:id" => "current_epc#live_epc", :as => enr_location_current_live_epc
in your view
<%= link_to 'PDF', enr_location_current_epc_pdf_path(#location) %>
<%= link_to 'LIVE', enr_location_current_live_epc_path(#location) %>
def pdf_url
if (params[:url] == 1)
do something
else
do something else
end
#epc = Enr::Rds::CurrentEpc.find_by_location_id(#location_id)
if #epc != nil
#epc.current_epc_path[-4..-1] == '.pdf'
content = open(#epc.current_epc_path, "rb") {|io| io.read }
send_data content, :filename => 'epc.pdf', :disposition => 'inline'
end
end
In your routes.rb:
match "/anything/pdf_url/:url" => "anything#pdf_url"
And your two links:
<%= link_to "first", "/anything/pdf_url/1" %>
<%= link_to "second", "/anything/pdf_url/2" %>
EDIT:
member is used when it requires an :id parameter, if not it is a collection. Anyway, I would use match in that case like (which is in parenthesis is optional):
match "/anything(/download/:url)" => "anything#index"
and get the parameter in your controller like this:
def index
if params[:url] == 1 # Or whatever you put in your link_to
# redirect_to url
else
# redirect_to url
end
end
EDIT 2:
Index controller:
def index
if params[:id]
#location_id = Location.find(params[:id])
#epc = Enr::Rds::CurrentEpc.find_by_location_id(#location_id)
if params[:url] == 'pdf'
#epc.current_epc_path[-4..-1] == '.pdf'
content = open(#epc.current_epc_path, "rb") {|io| io.read }
send_data content, :filename => 'epc.pdf', :disposition => 'inline'
elsif params[:url] == 'live'
#epc = Enr::Rds::XmlData.find_by_location_id(#location_id)
redirect_to #epc.report_url
end
else
#locations = Location.all
respond_to do |format|
format.html
format.json { render :json => #locations }
end
end
end
Your routes:
match "/anything(/:id(/:url))" => "anything#index"
Your view (change links to fit your tastes, it's just a simple example):
<%= link_to "first", "/anything/1/pdf" %>
<%= link_to "second", "/anything/1/live" %>

Rails GET not translating slugged id with extra parameters

I have a model which is linking to the show method:
<%= link_to "View Others", :controller => "browse",
:action => "show", :id => #id, :d => "25" %>
Clicking the link gives:
http://localhost:3000/browse/santa-cruz?d=25
Rails gives the error though:
No route matches {:controller=>"browse", :action=>"show", :id=>nil, :d=>"25"}
If I take the extra parameter off everything works.
<%= link_to "View Others", :controller => "browse",
:action => "show", :id => #id %>
Goes to http://localhost:3000/browse/santa-cruz
This page loads and I am getting the correct params[:id]
Any ideas?
Pasted bellow is the show for my controller
def show
if params[:d].nil? then
# Show list of addresses in city.
addresses = Address.where(:slug => params[:id])
profile = []
addresses.each do |ad|
profile << ad.profile
end
unless profile.blank?
#profile = Kaminari.paginate_array(profile).page(params[:page]).per(5)
#title = "Profiles Near " + addresses.first.city
#id = params[:id]
else
redirect_to :controller => 'pages', :action => 'notlaunched', :zip => params[:id]
end
else # :d exists
# show all within :d miles.
addresses = Address.where(:slug => params[:id])
nearby = Address.near("#{addresses.first.fulladdress}", params[:d], :order => :distance)
profiles = nearby.map{ |ad| ad.profile }.uniq
end
end
Here's the Index:
def index
cities = []
states = []
Address.find_each do |ad|
cities << { :city => ad.city, :slug => ad.slug } # slug becomes the :id of show
states << ad.state
end
#cities = cities.uniq
#states = states.uniq
#title = "Browse Cities"
end

Parameter in AJAX request

I have a view which contain multiple links:
<% a.each do |q| %>
<%= link_to "stock it",
{ :action => "stock",
:qid => q.question_id,
:qur => q.question_answers_url,
:qti => q.title } ,
:remote => true %>
<div id="<%= "stock" + q.question_id.to_s %>"></div>
<% end %>
Each link generate AJAX-request. Here is a controller:
def stock
if(!Later.where(:question_id => params[:qid]).exists?)
later = Later.new(:question_id => params[:qid], :name => params[:qti], :url => params[:qur])
later.save
end
respond_to do |format|
format.js { render :layout=>false }
end
end
Now return to the view. Each link has a 'div' with unique id='stock'. When user press the link I need to add text to specific div with corresponding id.
I have a stock.js.erb file:
$("#stock<number>").html("some text");
How can I pass div-id to stock.js.erb and how can I use it ?
Common use is to add object.id to your DOM id. That what you exactly did:
<div id="<%= "stock_#{q.question_id}" %>"></div>
Then in your controller you shoud define your question_id or your exact question:
def stock
if(!Later.where(:question_id => params[:qid]).exists?)
later = Later.new(:question_id => params[:qid], :name => params[:qti], :url => params[:qur])
later.save
end
#question_id = params[:qid]
end
Now it will be shared with your stock.js.erb file:
$("#stock_<%= #question_id %>").html("some text");
