  • Authentication in Rails, where to start?

    - by Victor P
    Hello. Im learning Rails by building apps. I want to make my first authenticated app: users signup, login, do some changes in models they have access to and logout. I did the Google search but it is quite confusing: many plugins, many tutorials. Don't know where to start. Is there a state-of-the-art authentication method for Rails? What do you use in Production to authenticate your users? Any help in this will be helpful. Thanks

  • Embed Git Commit Log in Rails App?

    - by Andrew
    So, I have a 'development blog' in a rails app I'm working on right now. I'm using Git for version control and deployment (although right now I'm the only person working on it). Now, when I make changes in Git I put a pretty decent log entry about what I've done. I'd love to have the Git commit log automatically posted to the development blog -- or otherwise available for others to read within the deployed site. Is there an automated way to pull the Git Commit Log into a view in a rails app?

  • Multiple Rails forks with separate designs and layouts

    - by mettadore
    I have a Rails project that is basically a simple web app for a membership-based organization. We've open sourced the code on Github for the web app so that others can use it, but have a licensed design/layout that the original organization is going to use. This layout cannot be open sourced. I was wondering if others have run into the situation where you have an open-source Rails app with a non-OS design. My initial thought is to put app/views in .gitignore, and to have anyone forking the code add their own views directory, perhaps including an app/views_default directory with a web-app-theme layout or something else to get people running. Is this the best option (realizing that there are other files such as JavaScript, CSS, etc that come with the layout that must also be ignored). Does anyone have some good thoughts or pointers on this?

  • Resolve HTTP 304 - not modified in AJAX call made via GWT

    - by Salvin Francis
    We are using an application made in GWT with the server as tomcat. The project runs fine normally, however there are situations where the server is restarted. At such point of time, the ajax call made by the code below returns blank text with the status code as 304 RequestBuilder requestBuilder = new RequestBuilder(RequestBuilder.POST, URL.encode(serverUrl)); //-- serverUrl is the url to which this call is posted to. requestBuilder.setHeader("Content-Type", "application/x-www-form-urlencoded"); requestBuilder.setHeader("Expires","0"); requestBuilder.sendRequest( postData, new RequestCallback() { public void onError(Request request, Throwable exception) { //Do nothing } public void onResponseReceived(Request request, Response response) { //sometimes when the server is restarted, I get response.getStatusCode() = 304 and the response.getText() as blank } } ); normally we get back some data from the server inside this response text. How do we now get the data when the response itself is blank ?

  • Problems using jQuery $.ajax to pass data

    - by iboeno
    I'm using ASP.NET and attempting to call a method with a signature of [WebMethod] public static string GetInfo(string id){...} using the following javascript: var elementValue = $("#element").attr('id'); var d = "{id : " + elementValue + "}"; $.ajax({ type: "POST", url: "../WebPage.aspx/GetInfo", data: d, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { //do this } }); And this is not working. If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails. Why is this happening, and how do I resolve it? On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.

  • JQuery Ajax Always Fires Error Function

    - by CccTrash
    AddFileToDB.ashx: public void ProcessRequest (HttpContext context) { context.Response.ContentType = "application/json"; context.Response.Write("{ \"filename\": \"test.jpg\" }"); } JQuery: $.ajax({ url: 'AddFileToDB.ashx', dataType: 'json', success: function(data) { alert(data.filename); }, error: function(data) { alert('error'); }, }); This always results in the error function being called. I don't know why? Thoughts? AddFileToDB.ashx gets fired, but success never gets run.

  • 1-st level routes for multiple resources in Rails

    - by Leonid Shevtsov
    I have a simple SEO task. There's a City model and a Brand model, and I have to create 1st-level URLs for both (e.g. site.com/honda and site.com/boston). What's the preferred routing/controller combination to do this in Rails? I can only think of map.connect '/:id', :controller => 'catchall', :action => 'index' class CatchallController < ApplicationController def index if City.exists?(:slug => params[:id]) @city = City.find_by_slug!(params[:id]) render 'cities/show' else @brand = Brand.find_by_slug!(params[:id]) render 'brands/show' end end end but it seems to be very un-Rails to put such logic into the controller. (Obviously I need to make sure that the slugs don't overlap in the models, that's done).

  • Ajax response is taking time to populate.

    - by Rachel
    I am having an util class which is not owned by me. I am calling one of the method of that util class which inturn calls one ajax function. And gives me response back. I need to make a decision depending on the response object. The problem is that response object takes some time to populate(mili seconds). var selector = dojo.byId("SelectorId"); var theChart = new chart( selector, 135, 92, style, frequency, time); if(theChart.data ===null){ console.log("No response"); }else{ Console.log("Use response data"); } and chart( selector, 135, 92, style, frequency, time); is not owned by me. chart() is from util class. above snippet works fine with break point. But when I remove the breakpoint it starts going in "if" block always. Hows can I solve this issue.

  • Jquery Ajax not receiving php response correctly

    - by Theo
    I'm sending a JSON response from php to jquery: foreach ( $obj as $o ) { $a[ $o->key] = utf8_encode($o->id); } die(json_encode($a)); my html/jquery code is: $.ajax({ type:'POST', url: "imoveis/carrega_bairros", data: ({cidade:10}), dataType:"json", success: function(ret) { alert(ret) if(ret.success) { // ... } else alert("error"); } }); The json response is perfect (i get it on the console), but jquery is receiving a NULL ret object and it alerts "error". What's the problem???

Something like Dreamweaver with the ability to browse Objects etc. If I have opened the _show.erb I create a div and selete @user.email. etc. Any suggestions?

  • JRuby on Rails deployment

    - by Vagmi Mudumbai
    I need to host a JRuby on Rails app on Mongrel. The problem is that I need to support mutual authentication. I know that I could just host it behind a Apache with mod_proxy use mod_ssl to pass the cred or part of the cred as a request header to rails. But I want the whole stack to be Java. Is there a Java application server that can do mod_proxy + ssl kind of configuration without me having to install Apache. Also, we need this to be platform independent. IIS or Apache+OpenSSL is actually not a preferred alternative. Any alternative deployment configurations are also welcome.

  • Trouble Upgrading Rails 2 Routes for a Redmine Plugin

    - by user1858628
    I am trying to get a Redmine plugin designed for Rails 2 to work with Rails 3. https://github.com/dalyons/redmine-todos-scrum-plugin I've pretty much fixed most parts, but having no success whatsoever in getting the routes to work.

Any help would be greatly appreciated.

  • Port a Rails App from Windows to Mac

    - by Ryan Max
    Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Is there any way I can port my app to this mac, without having to start over? I can't find any resources on the internets about this.

  • Processing large recordsets in Rails

    - by japancheese
    Hello, I'm trying to perform a daily operation on a larger than normal dataset (2m+ records). However, Rails seems to take a very long time performing operations on such a dataset. Operations like Dataset.all.each do |data| ... end take a very long time to complete (I assume this is because it can't fit all the items into memory at once, right?). Does anyone have any strategies on how I could handle this situation? I know SQL would probably speed up the process, but I'm looking to use the Rails environment as I can do many more complicated things to the data than I can with just SQL statements.

  • Starting socket server in ruby on rails on cloud environments (heroku)

    - by ElTren
    Hi, I'm using heroku, and I can push a Ruby on Rails app just fine, I'm trying to convert this to a Socket server, basically I would need to bind to an open port, in this case, I know Heroku only does 80 22 and 443. Is it possible to bind to port 80 on those environments? Also, how would I setup the entry point for this socket server, all I know is that when script/server it boots up the app. Do I have to put the function call there? How can a socket server start instead of the rails app on top of whatever webserver heroku has.

  • Best solution to wait for all ajax callbacks to be executed

    - by glaz666
    Hi! Imagine we have to sources to be requested by ajax. I want to perform some actions when all callbacks are triggered. How this can be done besides this approach: (function($){ var sources = ['http://source1.com', 'http://source2.com'], guard = 0, someHandler = function() { if (guard != sources.length) { return; } //do some actions }; for (var idx in sources) { $.getJSON(sources[idx], function(){ guard++; someHandler(); }) } })(jQuery) What I don't like here is that in this case I can't handle response failing (eg. I can't set timeout for response to come) and overall approach (I suppose there should be a way to use more power of functional programming here) Any ideas? Regards!

  • jQuery blockUI and AJAX POST

    - by oompahloompah
    I am using jQuery BlockUI in a project. For a particular user action, I want to block the UI, and then POST data to the server. When the timeout event occurs OR the server returns, I want to unblock the page. I can't seem to implement this behaviour. This is what I have so far (not working) $(document).ready(function(){ $('#test').click(function(event){ $.blockUI({ message: $('#syntax-chk') }); $.ajax({ type: 'POST', url: 'www.example.com', data: somedata, dataType: "json" }); setTimeout(function() { $.unblockUI({ onUnblock: function(){ alert('onUnblock'); } }); }, 2000); }); can anyone spot what I may be doing wrong?

  • Two drop down lists in Ajax and MySQL

    - by Milla
    I'm trying to learn some Ajax and MySQL... Basically, the code that I have right now is similar to: http://www.w3schools.com/PHP/php_ajax_database.asp I was wondering how should I modify those codes (both html, javascript and php) to create two drop down lists. The first drop list would be used for choosing the Lastname (eg. Swanson) and the second drop list would be used for choosing the Hometown (eg. Quahog). Then the user would click "Submit" button and the query would return the matching results (eg. all the Swansons living in Quahog). I'd be very thankful for all the ideas!
