  • Rails, Edit page update in a window

    - by Mike
    I have my code working so that I have a table of businesses. There's a pencil icon you can click on the edit the business information. The edit information comes up in a partial inside of a modal pop up box. The only problem is that once they make the changes they want and click update, it sends them to the 'show' page for that business. What I want to happen is have the pop up box close and have it update the information. This is my update function in my controller. def update @business = Business.find(params[:id]) respond_to do |format| if @business.update_attributes(params[:business]) flash[:notice] = 'Business was successfully updated.' format.html { redirect_to(business_url(@business)) } format.js else format.html { render :action => "edit" } format.xml { render :xml => @business.errors, :status => :unprocessable_entity } end end end I tried following railscast 43 and i created an .rjs file but I couldn't get that to work at all. My update was still taking me to the show page. Any help would be appreciated. EDIT: Added some more code. <% form_for(@business) do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> ... <%= f.label :business_category %><br /> <%= f.select :business_category_id, @business_categories_map, :selected => @business.business_category_id %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> This is my form inside of my edit page which is being called through the index in a pop up by: <div id="popupEdit<%=h business.id %>" class="popupContact"> <a class="popupClose<%=h business.id %>" id="popupClose">x</a> <% if business.business_category_id %> <% @business = business %> <%= render "business/edit" %> <% end %> </div>

  • zend_application showing blank page

'/data/server/settings.ini', APPLICATION_ENV ); self::$registry->configuration = $config; } protected function _initLogging() { $config = self::$registry->configuration; $logger = new Zend_Log(new Zend_Log_Writer_Stream($config->logging->file)); Zend_Registry::set('logger', $logger); } protected function _initFrontController() { self::$frontController = Zend_Controller_Front::getInstance(); self::$frontController->throwExceptions(true); self::$frontController->returnResponse(true); self::$frontController->setControllerDirectory( APPLICATION_PATH .'/controllers' ); self::$frontController->setParam('registry', self::$registry); return self::$frontController; } protected function _initView() { $config = self::$registry->configuration; $view = new Zend_View; $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer($view); Zend_Controller_Action_HelperBroker::addHelper($viewRenderer); Zend_Layout::startMvc( array( 'layoutPath' => APPLICATION_PATH .

Filenames / paths are intact. If I add die() to the bottom of my layout.phtml, I get the page. Something is resetting the headers and sending a blank page. My error reporting is on and I get unrelated errors. What could this be?! Thanks!

  • Ajax basic email code without reloading page

    - by Camran
    I have in a previous Q found out that I need an ajax-function to send an email (submit a contact form) without reloading the page. This is for my classifieds website, where when users are viewing a classified they have the option to "tip a friend" by entering their friends email-adress and submitting the form. But I don't want to reload the page, that would be frustrating and not so clever. The only input in the form is a text input which will contain the email-adress to send to, and another hidden input which contains the classified_id nr, to identify which classified it is. The website is php based btw... Does anybody have a simple script for this? I have no experience in Ajax at all... And would really appreciate it. Thanks PS: Would prefer no Jquery, due to clients own reasons...

  • Java: JSP halt execution on rest of page

    - by bguiz
    Hi, How do you stop a JSP from executing? I have JSPs which kick the user off a page by means of a "forward". public boolean kickIfNotLoggedIn( HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { //code to check if user is logged in req.getRequestDispatcher( ACCESS_DENIED_PAGE).forward(request, response); } In my JSP, I have this code, BEFORE any HTML output: <% //loginHelper.kickIfNotLoggedIn(request, response); if (!loginHelper.kickIfNotLoggedIn(request, response)) { return; } %> If I don't use the return statement, the JSP continues processing, and I get a NullPointerException. If I use the return statement (as is commonly suggested on various sources on the net), I get an IllegalStateException: StandardWrapperValve[jsp]: PWC1406: Servlet.service() for servlet jsp threw exception java.lang.IllegalStateException: PWC3991: getOutputStream() has already been called for this response at org.apache.coyote.tomcat5.CoyoteResponse.getWriter(CoyoteResponse.java:717) at org.apache.coyote.tomcat5.CoyoteResponseFacade.getWriter(CoyoteResponseFacade.java:226) at org.apache.jasper.runtime.JspWriterImpl.initOut(JspWriterImpl.java:187) Any ideas how to fix this, or another way to achieve an access denied page? Thanks

  • Discovering maximum packet size

    - by ereOn
    I'm working on a network-related project and I am using DTLS (TLS/UDP) to secure communications. Reading the specifications for DTLS, I've noted that DTLS requires the DF flag (Don't Fragment) to be set. On my local network if I try to send a message bigger than 1500 bytes, nothing is sent. That makes perfect sense. On Windows the sendto() reports a success but nothing is sent. I obviously cannot unset the DF flag manually since it is mandatory for DTLS and i'm not sure whether the 1500 bytes limit (MTU ?) could change in some situations. I guess it can. So, my question is : "Is there a way to discover this limit ?" If not, what would be the lowest possible value ? My software runs under UNIX (Linux/MAC OSX) and Windows OSes so different solutions for each OS are welcome ;) Many thanks.

  • How to navigate to another html page?

    - by newbie
    In my application there's a usual login page sending username and password to the server script, where it needs to be authenticated, and in case of an authentic user, the server should redirect to a page student.html. This is my code var ports = 3000; var portt = 3001; var express = require('express'); var student = require('express')(); var teacher = require('express')(); var server_s = require('http').createServer(student); var server_t = require('http').createServer(teacher); var ios = require('socket.io').listen(server_s); var iot = require('socket.io').listen(server_t); var path = require('path'); server_s.listen(ports); server_t.listen(portt); student.use(express.static(path.join(__dirname, 'public'))); student.get('/', function(req,res){ res.sendfile(__dirname + '/login.html'); }); teacher.use(express.static(path.join(__dirname, 'public'))); teacher.get('/', function(req,res){ res.sendfile(__dirname + '/mytry.html'); }); ios.sockets.on('connection', function(socket){ var username, password; socket.on('check',function(data){ username = data[0]; password = data[1]; //************* Database connection and query ************* var mysql = require('mysql'); var connection = mysql.createConnection({ host : 'localhost', user : 'user', password: '*******', database: 'my_db' }); connection.connect(); var qstring = 'SELECT s_id FROM login_student WHERE username='+username+'AND password='+password; connection.query(qstring, function(err, rows, fields) { if (err) { console.log('ERROR: ' + err); socket.emit('login_failure','DB error'); return; } console.log('The solution is: ', rows[0].solution); if (rows>0) //***** Here i want redirection to another page ****** else socket.emit('login_failure','Invalid Username or password'); }); connection.end(); }); }); iot.sockets.on('connection', function(socket){ ; }); }); Can anyone suggest what should I do?

  • CSS: Size of buttons in Chrome is different than Firefox

    - by Hank
    I have the following HTML code: <style type="text/css"> .submitbutton{margin-left:-2px} </style> ... <form> ... <input class=submitbutton type=submit value="Create Listings" /> </form> In Firefox, the input button has more padding than in Chrome. Any ideas why? UPDATE: If you're wondering why I have the negative margin - it's because between the input field and the input button - there is too much space.

  • Is there a buffer size attached to stdout?

    - by jameswelle
    I am trying to find some information on data limits related to stdout on Windows. I can't seem to find the information on MSDN. Is there a limit to how much data can be written to stdout? If so, what happens if the limit is reached? Is the data lost? If stdout is redirected (for example, by launching the process from .Net and using the ProcessStartInfo.RedirectStandardOutput property), does that have any effect on how much data can be written? As I read from the stdout stream in the calling process, does that affect the limitations? Are these limits related in any way to named pipes?

  • How do i handle a heavy page?

    - by Ulhas Tuscano
    I have been asked to design & develop a page in asp.net which contains 7 tabs.Each table contains 2 Editable gridview & clicking on gridview cell should open a popup & that popup will open a new popup ( I would say nested popup). even when i switch from one tab to another. It should hold the griddata & whenever user will finish all the operations he/she will click on save button which will save all the data contained in the tabs. The page is really too too too heavy. It will definitely take a long time to load as it contains gridview operations , popup related jobs, tab data & tab switching. I am finding the best way i can achieve this with an acceptable speed of operation. Any suggestions or help would be greatly appreciated.

  • All site interaction through a single page

    - by Jacques Wolfghang
    Hi there I have an idea for a site where there would be no refreshing and all interactions take place via AJAX. The page would load with central space, where all interaction would take place. If a user clicked on a link, the page would request it via AJAX and replace the rectangle's content with the link content. The idea is effectively an AJAX implemented iframe. Are there any disadvantages with this approach? Does anyone have any suggestions or thoughts on the idea? Thank You for your time Note: I am sorry if it is not clear or hard to understand, English is not my mother tongue. If there is anything you would like made clearer, please comment and I will try my best to make it understood.

  • Multiple ASP.Net Controls On One Page

    - by Duracell
    We have created a User Control for ASP.Net. At any one time, a user's profile page could contain between one and infinity of these controls. The Control.ascx file contains quite a bit of javascript. When the control is rendered by .Net to HTML, you notice that it prints the javascript for each control. This was expected. I'd like to reduce the amount of HTML output by the server to increase page load times. Normally, you could just move the javascript to an external file and then you only need one extra HTTP request which will serve for all controls. But what about instances in the javascript where we have something like document.getElementById('<%= txtTextBox.ClientID %'); How would the javascript know which user control work with? Has anyone done something like this, or is the solution staring me in the face?

  • Updating a session variable on a page that uses enablesessionstate=readonly attribute doesn't fail f

    - by chandmk
    Asp.Net allows you you set the session state to readonly at individual page level or in the web.config for all pages. But it doesn't prevent you from creating a brand new session variable on that page or modify an existing session variable. But when you try to use that session variable it is either not available or its value is not modified. Why wouldn't the asp.net framework throw a run time error, if not compile time error, when a write attempt is made to a session on the pages where that is not allowed?

  • Java heap size - will this work?
