  • How to escape HAML for Javascript in Sinatra

    - by viatropos
    I would like to return a list/combobox from an ajax request ("Which on of these do you like?" type thing). I would like to write that little snippet in HAML, which converts it to HTML, but when I do, the page goes blank. I'm assuming this is because the HTML isn't escaped. Is there a way to escape HAML so I can do $("#mydiv").html(response);? Here's the method: post "/something" do # process... haml :"partials/_select", :layout => false, :locals => {:collection => choices} end ... the haml template: %select - collection.each do |item| %option{:value => item.to_s}= item.to_s ... and the javascript: success: function(responseText, statusText, xhr, $form) { $(".dialog_content").append(responseText); } I have tried the sinatra_more plugin and the escape_javascript method, but there's problems with the haml buffer in sinatra. Any ideas?

  • Creating an admin user in Devise on Rails beta 3

    - by erskingardner
    Ok, I'm probably going to feel quite dumb when someone answers this one with a simple thing that I'm missing but... here goes: I've got a brand new app on rails 3 beta and I'm using devise for the authentication. I've run all the comments and everything is working perfectly at the moment. I've created a user role and an admin role (following these instructions: http://wiki.github.com/plataformatec/devise/adding-an-admin-role) and I've registered myself as the first user but how to do I register or create an admin role user? The directions from the devise guys setup the admin role to not be registerable but I'm unsure how you're supposed to create the admin if you can't register?! Any help would be appreciated! Thanks!

  • Using will_paginate with AJAX live search with jQuery in Rails

    - by Mark Richman
    I am using will_paginate to successfully page through records. I am also using AJAX live search via jQuery to update my results div. No problem so far. The issue I have is when trying to paginate through those live search results. I simply get "Page is loading..." with no div update. Am I missing something fundamental? # index.html.erb <form id="searchform" accept-charset="utf-8" method="get" action="/search"> Search: <input id="search" name="search" type="text" autocomplete="off" title="Search location, company, description..." /> <%= image_tag("spinner.gif", :id => "spinner", :style =>"display: none;" ) %> </form> # JobsController#search def search if params[:search].nil? @jobs = Job.paginate :page => params[:page], :order => "created_at desc" elsif params[:search] and request.xhr? @jobs = Job.search params[:search], params[:page] end render :partial => "jobs", :layout => false, :locals => { :jobs => @jobs } end # Job#search def self.search(search, page) logger.debug "Job.paginate #{search}, #{page}" paginate :per_page => @@per_page, :page => page, :conditions => ["description LIKE ? or title LIKE ? or company LIKE ?", "%#{search}%", "%#{search}%", "%#{search}%"], :order => 'created_at DESC' end # search.js $(document).ready(function(){ $("#search").keyup(function() { $("#spinner").show(); // show the spinner var form = $(this).parents("form"); // grab the form wrapping the search bar. var url = form.attr("action"); // grab the URL from the form's action value. var formData = form.serialize(); // grab the data in the form $.get(url, formData, function(html) { // perform an AJAX get, the trailing function is what happens on successful get. $("#spinner").hide(); // hide the spinner $("#jobs").html(html); // replace the "results" div with the result of action taken }); }); });

  • Charset and POST request

    - by jriff
    Hi All! I have a Rails 2.3.5 application that is working fine with UTF-8 and international characters. Now I have made some integration to a payment gateway where I POST some data, wait a while and get a POST back. The problem is that when I get that post back the international characters are broken. Instead of "sørensen" I get: "sørensen". If I do an iconv -fISO-8859-1 -tUTF8 it gets correctly converted to the former (I do that from a OS X command prompt). I have examined the POST request with logger.info(request.headers.inspect) in my controller and I can see that no charset parameter is given. As far as I can see the POST from the gateway must be UTF8 since one character (ø) gets translated to two (ø). So why does Rails think that the POST is ISO-8859-1? I know that one solution is to simply convert the params-hash with Iconv in the controller but I would like to know what is happening. Thanks in advance. Regards, Jacob

  • redirect to a route alias on a form validation error

    - by Kevin Monk
    If I'm on a route alias such as /register and I have a form error and I render :new, is it possible for the path to be /register still? At the moment it is rendering /new I could do a redirect_to register_path but then I would lose the params? It's making the following test fail: Scenario: Try registering with a bad staff number Given I am on the registration page When I fill in "email" with "[email protected]" And I fill in "First Name" with "Kevin" And I fill in "last name" with "Monk" And I fill in "Employee Number" with "something barking123" And I press "Register" Then I should be on the registration page And I should see "Your employee ID number looks incorrect."

  • Wrapping my head around MongoDB, mongomapper and joins...

    - by cbmeeks
    I'm new to MongoDB and I've used RDBMS for years. Anyway, let's say I have the following collections: Realtors many :bookmarks key :name Houses key :address, String key :bathrooms, Integer Properties key :address, String key :landtype, String Bookmark key :notes I want a Realtor to be able to bookmark a House and/or a Property. Notice that Houses and Properties are stand-alone and have no idea about Realtors or Bookmarks. I want the Bookmark to be sort of like a "join table" in MySQL. The Houses/Properties come from a different source so they can't be modified. I would like to be able to do this in Rails: r = Realtor.first r.bookmarks would give me: House1 House2 PropertyABC PropertyOO1 etc... There will be thousands of Houses and Properties. I realize that this is what RDBMS were made for. But there are several reasons why I am using MongoDB so I would like to make this work. Any suggestions on how to do something like this would be appreciated. Thanks!

  • ActionController::MethodNotAllowed

    - by Lowgain
    I have a rails model called 'audioclip'. I orginally created a scaffold with a 'new' action, which I replaced with 'new_record' and 'new_upload', becasue there are two ways to attach audio to this model. Going to /audioclips/new_record doesn't work because it takes 'new_record' as if it was an id. Instead of changing this, I was trying to just create '/record_clip' and '/upload_clip' paths. So in my routes.db I have: map.record_clip '/record_clip', :controller => 'audioclips', :action => 'new_record' map.upload_clip '/upload_clip', :controller => 'audioclips', :action => 'new_upload' When I navigate to /record_clip, I get ActionController::MethodNotAllowed Only get, head, post, put, and delete requests are allowed. I'm not extremely familiar with the inner-workings of routing yet. What is the problem here? (If it helps, I have these two statements above map.resources = :audioclips

  • Rails Autocompletion Issue - Rails 1.2.3 to 2.3.5

    - by Grant Sayer
    I have an issue with rails Autocompletion from some code that i've inherited from an old Rails 1.2.3 project that I'm porting to Rails 2.3.5. The issue revolves around javascript execution within the auto_complete helper :after_update_element. The scenario is: A user is presented with a popup form with a number of fields. In the first field as they enter text the auto_complete AJAX call occurs, returning a result, plus a series of other HTML data wrapped in <divs> so that the after_update_element call can iterate over the other data and fill in the remaining fields. The issue lies with the extraction of the other fields which works on IE, fails on Firefox. Here is the code: <%= text_field_with_auto_complete :item, :product_code, {:value => ""}, {:size => 40, :class => "input-text", :tabindex => 6, :select => 'code', :with => "element.name + '=' + escape(element.value) + '&supplier_id=' + $('item_supplier_id').value", :after_update_element => "function (ele, value) { $('item_supplier_id').value = Utilities.extract_value(value, 'supplier_id'); $('item_supplied_size').value = Utilities.extract_value(value, 'size')}"}%> Now the function Utilities is designed to grab the fields from the string of values and looks like: // // Extract a particular set of data from the autocomplete actions // Utilities.extract_value = function (value, className) { var result; var elements = document.getElementsByClassName(className, value); if (elements && elements.length == 1) { result = elements[0].innerHTML.unescapeHTML(); } return result; }; In Firefox the value of result is undefined

    Hey. I am trying to filter Client Comments by using a select and rendering it in a partial. Right now the partial loads @client.comments. I have a Category model with a Categorizations join.

  • sql charateristic function for avg dates

    I have a query which I use to grab specific dates and a price for the date, but now I'd like to use something similar to grab the avg prices for particular days of the week.

  • nested attributes with polymorphic has_one model

    - by Millisami
    I am using accepts_nested_attributes_for with the has_one polymorphic model in rails 2.3.5 Following are the models and its associations: class Address < ActiveRecord::Base attr_accessible :city, :address1, :address2 belongs_to :addressable, :polymorphic => true validates_presence_of :address1, :address2, :city end class Vendor < ActiveRecord::Base attr_accessible :name, :address_attributes has_one :address, :as => :addressable, :dependent => :destroy accepts_nested_attributes_for :address end This is the view: - form_for @vendor do |f| = f.error_messages %p = f.label :name %br = f.text_field :name - f.fields_for :address_attributes do |address| = render "shared/address_fields", :f => address %p = f.submit "Create" This is the partial shared/address_fields.html.haml %p = f.label :city %br= f.text_field :city %span City/Town name like Dharan, Butwal, Kathmandu, .. %p = f.label :address1 %br= f.text_field :address1 %span City Street name like Lazimpat, New Road, .. %p = f.label :address2 %br= f.text_field :address2 %span Tole, Marg, Chowk name like Pokhrel Tole, Shanti Marg, Pako, .. And this is the controller: class VendorsController < ApplicationController def new @vendor = Vendor.new end def create @vendor = Vendor.new(params[:vendor]) if @vendor.save flash[:notice] = "Vendor created successfully!" redirect_to @vendor else render :action => 'new' end end end The problem is when I fill in all the fileds, the record gets save on both tables as expected. But when I just the name and city or address1 filed, the validation works, error message shown, but the value I put in the city or address1, is not persisted or not displayed inside the address form fields? This is the same case with edit action too. Though the record is saved, the address doesn't show up on the edit form. Only the name of the Client model is shown. Actually, when I look at the log, the address model SQL is not queried even at all.

  • FasterCSV Parsing issue?

    - by Schroedinger
    G'day guys, I'm currently using fastercsv to construct ActiveRecord elements and I can't for the life of me see this bug (tired), but for some reason when it creates, if in the rake file i output the column I want to save as the element value, it puts out correctly, as either a Trade or a Quote but when I try to save it into the activerecord, it won't work. FasterCSV.foreach("input.csv", :headers => true) do |row| d = DateTime.parse(row[1]+" "+row[2]) offset = Rational(row[3].to_i,24) o = d.new_offset(offset) t = Trade.create( :name => row[0], :type => row[4], :time => o, :price => row[6].to_f, :volume => row[7].to_i, :bidprice => row[10].to_f, :bidsize => row[11].to_i, :askprice => row[14].to_f, :asksize => row[15].to_i ) end Ideas? Name and Type are both strings, every other value works except for type. Have I missed something really simple?

  • rails + compass: advantages vs using haml + blueprint directly

    - by egarcia
    I've got some experience using haml (+sass) on rails projects. I recently started using them with blueprintcss - the only thing I did was transform blueprint.css into a sass file, and started coding from there. I even have a rails generator that includes all this by default. It seems that Compass does what I do, and other things. I'm trying to understand what those other things are - but the documentation/tutorials weren't very clear. These are my conclusions: Compass comes with built-in sass mixins that implement common CSS idioms, such as links with icons or horizontal lists. My solution doesn't provide anything like that. (1 point for Compass). Compass has several command-line options: you can create a rails project, but you can also "install" it on an existing rails project. A rails generator could be personalized to do the same thing, I guess. (Tie). Compass has two modes of working with blueprint: "basic" and "semantic" usage. I'm not clear about the differences between those. With my rails generator I only have one mode, but it seems enough. (Tie) Apparently, Compass is prepared to use other frameworks, besides blueprint (e.g. YUI). I could not find much documentation about this, and I'm not interested on it anyway - blueprint is ok for me (Tie). Compass' learning curve seems a bit stiff and the documentation seems sparse. Learning could be a bit difficult. On the other hand, I know the ins and outs of my own system and can use it right away. (1 point for my system). With this analysis, I'm hesitant to give Compass a try. Is my analysis correct? Are Am I missing any key points, or have I evaluated any of these points wrongly?

  • How do I get the "Install Missing Plugin" yellow bar to appear in firefox when flash is not installe

    - by Janak
    My rails website uses the open_flash_graph plugin to generate flash graphs for my clients. If a customer doesn't have flash installed, it doesn't display any messages, it simply doesn't show any graphs. I've noticed that if I go to other websites that need flash, I get a yellow bar at the top of my firefox window that offers to "Install Missing Plugin". I assume something in the HTML lets firefox know that this webpage needs flash. What code do I need to add to my website to make this work?

  • Weird response for controller.request.format.html? in Rails

    - by Tony
    In my main controller, I have this: class MainController < ApplicationController before_filter do |controller| logger.info "controller.request.format.html? = #{controller.request.format.html?}" logger.info "controller.request.format.fbml? = #{controller.request.format.fbml?}" controller.send :login_required if controller.request.format.html? controller.send :facebook_auth_required if controller.request.format.fbml? end As expected, I get "true" for the ...fbml? line if a request comes from Facebook (my facebooker gem automatically sets the format). However, I get "5" for the ...html? line if the request comes from Facebook. Why would a method with a ? ever return a "5"? Isn't that against Rails conventions? Also, I think "5" is considered true so this might mess up my filters. Still looking into that... Any ideas?
