  • Rails ajax jquery problem

    - by user283179
    Ok I have this problem I'm trying to use Jquery to load a partial in replace of a listed object. loadshow: $(function() { $(".style_image_<%= style.id %> a").click(function() { $(".style_image_<%= style.id %>").html("loading... ") $(".style_image_<%= style.id %>").html("<%= escape_javascript(render("show")) %>") $.get(this.href, null, null, "html"); return false; }); }); _show.html.erb: <%=link_to image_tag(style.cover.pic.url(:normal)), style %> I'm getting this error: missing ) after argument list [Break on this error] $(".style_image_<%= style.id %>").htm...scape_javascript(render("show")) %>")\n There is two problems with my code here the first is the click function is not targeting the .style_image_<%= style.id % .... i.e (.style_image_42) if I replace the css target with 42 instead of _style.id the click target works; why is this? And with or without this change the _show partial is not render and the above error is given. Not really that good with Javascript any help would be great! P.s. The effect I really want is like one of those super cool cargo themes: http://cargocollective.com/publikspace Thanks Dan!

  • How to stay DRY when using both Javascript and ERB templates (Rails)

    - by user94154
    I'm building a Rails app that uses Pusher to use web sockets to push updates to directly to the client. In javascript: channel.bind('tweet-create', function(tweet){ //when a tweet is created, execute the following code: $('#timeline').append("<div class='tweet'><div class='tweeter'>"+tweet.username+"</div>"+tweet.status+"</div>"); }); This is nasty mixing of code and presentation. So the natural solution would be to use a javascript template. Perhaps eco or mustache: //store this somewhere convenient, perhaps in the view folder: tweet_view = "<div class='tweet'><div class='tweeter'>{{tweet.username}}</div>{{tweet.status}}</div>" channel.bind('tweet-create', function(tweet){ //when a tweet is created, execute the following code: $('#timeline').append(Mustache.to_html(tweet_view, tweet)); //much cleaner }); This is good and all, except, I'm repeating myself. The mustache template is 99% identical to the ERB templates I already have written to render HTML from the server. The intended output/purpose of the mustache and ERB templates are 100% the same: to turn a tweet object into tweet html. What is the best way to eliminate this repetition? UPDATE: Even though I answered my own question, I really want to see other ideas/solutions from other people--hence the bounty!

  • Save has_and_belongs_to_many link in basic RoR app

    - by Stéphane V
    I try to learn the has_and_belongs_to_many relationship between my 2 fresh new and simple models Product and Author, where a Product can have many authors and where author can have a lots of products. I wrote this : class Author < ActiveRecord::Base has_and_belongs_to_many :products end class Product < ActiveRecord::Base has_and_belongs_to_many :authors end In the partial form of view for the products, I have : <p>Products</p> <%= collection_select(:product, :author_ids, @authors, :id, :name, :prompt => " ", :multiple => true) %> but when I hit the update button, I get this strange message I can't resolve myself : NoMethodError in ProductsController#update undefined method `reject' for "1":String Rails.root: /home/stephane/www/HABTM Application Trace | Framework Trace | Full Trace app/controllers/products_controller.rb:63:in block in update' app/controllers/products_controller.rb:62:inupdate' Request Parameters: {"utf8"="✓", "_method"="put", "authenticity_token"="2GlTssOFjTVZ9BikrIFgx22cdTOIJuAB70liYhhLf+4=", "product"={"title"="Le trésor des Templiers", "original_title"="", "number"="1", "added_by"="", "author_ids"="1"}, "commit"="Update Product", "id"="1"} What's wrong ? Is there a problem with :product_ids... I saw on internet I had to pu a "s" but I'm not sure of what it represents.... How can I link the table authors_products to the key which is given back by the drop-down menu ? (here "author_ids"="1") Thx !

  • Rails 3.1 assets not recognizing new images uploaded by rmagick until server restart

    - by Mr_Nizzle
    I have my Rails 3.1.0 application running with passenger in production environment and I have a section where the application allows the user to change his profile picture so I upload the image using an ajax uploader and in my controller I upload the file and generate different sizes for the image with rmagick then I render the new image with an image_tag but the application won't show the image till I restart the server. What I get is No route matches [GET] "assets/path/to/image.png" If I restart the server It will show the image, but obviously I can't be restarting the server every once a user uploads a new image. How can I solve the keeping the assets working the right way?

  • Rails fields_for parameters for a has_many relation don't yield an Array in params

    - by user1289061
    I have a model Sensor with has_many and accepts_nested_attributes_for relationships to another model Watch. In a form to update a Sensor, I have something like the following <%= sensor_form.fields_for :watches do |watches_form| %> <%= watches_form.label :label %><br /> <%= watches_form.text_field :label %> <% end %> This is indended to allow editting of the already-created Watches belonging to a Sensor. This call spits form inputs as so: <input name="sensor[watches_attributes][0][label]" ... /> <input name="sensor[watches_attributes][0][id]" ... /> When this gets submitted, the params object in the Sensor controller gets an assoc like "sensor" => { "id"=>"1", "watches_attributes"=> { "0"=>{"id" => "1", "label" => "foo"}, "1"=>{"id" => "2", "label" => "bar"} } } For a has_many, accepts_nested_attributes_for update to work upon the @sensor.update_attributes call, it seems that that attributes key really must map to an Array. From what I've seen in the examples, the combination of has_many, accepts_nested_attributes_for, and sensor_form.fields_for should allow me to pass the resulting params object directly to @sensor.update_attributes and update each related object as intended. Instead the Sensor takes place, with no errors, but the Watch objects are not updated (since "watches_attributes" maps to a Hash instead of an Array?) Have I missed something?

  • 406 Not Acceptable error when using Jquery $.post in Firefox but not in Safari or Chrome

    - by jlfenaux
    I'm using Jquery (1.3.2) $.post command to trigger an ajax call to a rails server. The code works great on Safari and on Google Chrome (mac), but when I tried it on Firefox (3.5.7), I got a weird '406 Not Acceptable' error. When I look at the headers, it Firefox indicated that it accepted only ' text/javascript' responses. And the response Content-Type was 'text/html; charset=utf-8'. In Chrome the accepted types were 'application/json, text/javascript, /, text/javascript' and the response Content-Type was 'application/json; charset=utf-8'. I tried to force the content type in rails to 'text/javascript' format.json do render :json => @races.to_json, :content_type => 'text/javascript' end The content type is indeed changed in Chrome, but not in Firefox where it remains 'text/html'. Here is the code I used to trigger the ajax call. $.post( "/locator", params, function(data){...}, "json" ); Is there something I can do to make this work in Firefox? Thanks

  • How can I save an entire list of items true or false?

    - by JZ
    I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list. I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt: controller logic: def yardsign Add.update_all(["yardsign=?", true], :id => params[:yard_ids]) redirect_to adds_path end html.erb: <%= form_tag yardsign_adds_path, :method => :put do %> <% @adds.each do |add| %> <td><%= check_box_tag "yard_ids[]", add.id %></td> <% end %> <% end %> routes.rb resources :adds do collection do put :yardsign end end Terminal Started POST "/adds/yardsign" for 127.0.0.1 at 2010-04-15 19:22:49 Processing by AddsController#yardsign as HTML Parameters: {"commit"=>"Update", "yardsigntakers"=>["1", "2"], "authenticity_token"=>"3arhsxg/Ky+0W7RNM2T3QditMTJmOnLR5CqmMYWN4Qw="} User Load (0.3ms) SELECT "users".* FROM "users" WHERE ("users"."id" = 1) LIMIT 1 SQL (1.8ms) UPDATE "adds" SET yardsign='t' WHERE ("adds"."id" IN (1, 2)) Redirected to http://localhost:3000/adds

  • Limit a user to view only associated records in rails

    - by trobrock
    I have an application with three Models (Profile - SubModel - SubSubModel) chained together with has many relationships. I am trying to limit a user, after logging in, to only retrieving records that are associated with their Profile. I am very new to rails and this is what I had been trying in the Profile model has_many :submodels, :conditions => {:profile_id => self.id} but this is returning an empty data set when calling with Profile.find_by_id(1).submodels, how else could I achieve what I am trying to do. Or should I handle this in the controller or view instead, I thought it sounded well suited for the model to handle this.

  • Appending empty query string param to the URL in Rails

    - by Termopetteri
    Is there a way to append something to the query string with no value set? I would like to see this kind of URL being generated: http://local/things?magic. What I'm looking for is when the user goes to http://local/other?magic then every URL in the generated page would contain magic in the end. Following code is almost a solution but it gives me http://local/things?magic=. There is an extra = that I don't want there. def default_url_options(options) if params.has_key?("magic") { :magic => "" } end end Setting { :magic => nil } will remove the magic entirely from the generated URLs.

  • Sending data remotely from iPhone native apps to Rails apps

    - by jpartogi
    Dear all, I have decided to develop a native iPhone apps as a compliment to our webapps. Now I am wondering what are my options to send data remotely from the iPhone apps - since the database is online - to our online database. What I can think of on top of my head - since I come from web dev background - is JSON. My webapps is built using Rails, so I figure it would not be difficult to accept JSON request from the iPhone apps. But the next question is, is it difficult to send JSON data remotely from the iPhone apps? If JSON is not recommendable, what are my other options? Thank you so much for the assistance. Really appreciate it.

  • "PGError: no connection to the server" after idle

    After my application sits idle overnight, when I try to access it in the morning I get a 500 Internal server error and the logs indicate "PGError: no connection to the server".

  • Is it possible to do AJAX calls in a liquid template?

    - by Brian Armstrong
    I'm looking at the liquid templating language for Rails apps: http://wiki.github.com/tobi/liquid/ I'd like my users to also be able to make AJAX calls (just like the ones in rails for periodically_call_remote, observe_field, etc). Is this possible? Assuming the rails helpers can be added as filters, how will the user be able to modify what gets returned by the AJAX call? They cannot modify an rjs file on the server or anything like that. I suppose the AJAX call could return JSON (instead of rendered html) and then the javascript could use that to render something. But I'm having a little trouble envisioning how it would work exactly. If anyone can point me to an example of this or clarify it'd be much appreciated. Thanks!

  • Arbitrary attributes error with has_one association and Factory Girl

    - by purpletonic
    I'm trying to build a basic shopping cart for a Rails app I'm working on. Nothing special, - the shopping cart has many line_items - each line_item has_one product associated and a quantity with it class Cart < ActiveRecord::Base attr_accessible :line_items has_many :line_items, :dependent => :destroy end class LineItem < ActiveRecord::Base attr_accessible :quantity, :product belongs_to :cart has_one :product end I'm trying to use RSpec to test this association, but i'm doing something wrong as I'm getting an error that says: DEPRECATION WARNING: You're trying to create an attribute 'line_item_id'. Writing arbitrary attributes on a model is deprecated, and I'm not sure why. In my factories.rb file I'm defining the line_item factory as follows: factory :line_item do quantity { Random.rand(1..5) } product end factory :cart do factory :cart_with_two_line_items do ignore do line_item_count 2 end after(:create) do |cart, evaluator| FactoryGirl.create_list(:line_item, evaluator.line_item_count, cart_id: cart) end end end Any pointers where I'm going wrong, it's probably something basic, but I'm still quite new to Rspec. Thanks in advance.

  • Validation not bubbling up to my other models.

    - by DJTripleThreat
    Ok, I have a relationship between People, Users and Employees such that All Employees are Users and all Users are People. Person is an abstract class that User is derived from and Employee is derived from that. Now... I have an EmployeesController class and the create method looks like this: def create @employee = Employee.new(params[:employee]) @employee.user = User.new(params[:user]) @employee.user.person = Person.new(params[:person]) respond_to do |format| if @employee.save flash[:notice] = 'Employee was successfully created.' format.html { redirect_to(@employee) } format.xml { render :xml => @employee, :status => :created, :location => @employee } else format.html { render :action => "new" } format.xml { render :xml => @employee.errors, :status => :unprocessable_entity } end end end As you can see, when I'm using the :polymorphic => true clause, the way you access the super class is by doing something like @derived_class_variable.super_class_variable.super_super_etc. The Person class has a validates_presence_of :first_name and when it is satisfied, on my form, everything is OK. However, if I leave out the first name, it won't prevent the employee from being saved. What happens is that the employee record is saved but the person record isn't (because of the validation). How can I get the validation errors to show up in the flash object?

  • rails i18n - translating text with inside.

    - by egarcia
    Hi there! I'd like to i18n a text that looks like this: Already signed up? Log in! Note that there is a link on the text. On this example it points to google - in reality it will point to my app's log_in_path. I've found two ways of doing this, but none of them looks "right". The first way I know involves having this my en.yml: log_in_message: "Already signed up? <a href='{{url}}'>Log in!</a>" And in my view: <p> <%= t('log_in_message', :url => login_path) %> </p> This works, but having the <a href=...</a> part on the en.yml doesn't look very clean to me. The other option I know is using localized views - login.en.html.erb, and login.es.html.erb. This also doesn't feel right since the only different line would be the aforementioned one; the rest of the view (~30 lines) would be repeated for all views. It would not be very DRY. I guess I could use "localized partials" but that seems too cumberstone; I think I prefer the first option to having so many tiny view files. So my question is: is there a "proper" way to implement this?

  • Multiple forms on a single page

    - by normalocity
    I've got an app that's in invite-only beta right now. Problem is, I can't get the invite system to work. :( On my root page there's a login form (which works just fine), and I'm trying to add a "request invite" form on the same page. I started doing it by putting the form for InviteRequest (ActiveRecord) inside a partial, in the "views" folder for "InviteRequest". The app is definitely calling this partial, but I'm getting the following error: NoMethodError in User_sessions#new Showing app/views/invite_request/_new.html.erb where line #2 raised: undefined method `invite_requests_path' for #<ActionView::Base:0x25b3248> Extracted source (around line #2): 1: <% @invite_request = InviteRequest.new() %> 2: <% form_for @invite_request do |ir| %> 3: <%= ir.label :email %> 4: <%= ir.text_field :email %> 5: <% end %> I also read through the "Multiple Models in a Form" section of my trusty copy of "Agile Web Development with Rails", about maybe doing this with a "fieldset" tag, but not sure if this is the right approach. Thx.

  • How do I add the Disqus comment system to a Rails application in a similar fashion to Wordpress?

    - by Eric Lubow
    In Wordpress, the Disqus plugin allows you to choose to subscribe to a post via RSS or via email. Is there a pluign similar to the Wordpress plugin for Rails. Norman's Disqus plugin just uses the Disqus site to make it work. I was hoping to have things more stored locally. For an example of what I mean, take a look at this blog entry. I already know that since Rails (this application in particular) is using Authlogic (plus Facebook Connect), that Disqus cannot be too tightly coupled with the Authentication system. Has anyone ever done this or figured out a way to do this?
