  • TypeError: Object {...} has no method 'find' - when using mongoose with express

    - by sdouble
    I'm having trouble getting data from MongoDB using mongoose schemas with express. I first tested with just mongoose in a single file (mongoosetest.js) and it works fine. But when I start dividing it all up with express routes and config files, things start to break. I'm sure it's something simple, but I've spent the last 3 hours googling and trying to figure out what I'm doing wrong and can't find anything that matches my process enough to compare. mongoosetest.js (this works fine, but not for my application) var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/meanstack'); var db = mongoose.connection; var userSchema = mongoose.Schema({ name: String }, {collection: 'users'}); var User = mongoose.model('User', userSchema); User.find(function(err, users) { console.log(users); }); These files are where I'm having issues. I'm sure it's something silly, probably a direct result of using external files, exports, and requires. My server.js file just starts up and configures express. I also have a routing file and a db config file. routing file (allRoutes.js) var express = require('express'); var router = express.Router(); var db = require('../config/db'); var User = db.User(); // routes router.get('/user/list', function(req, res) { User.find(function(err, users) { console.log(users); }); }); // catch-all route router.get('*', function(req, res) { res.sendfile('./public/index.html'); }); module.exports = router; dbconfig file (db.js) var mongoose = require('mongoose'); var dbHost = 'localhost'; var dbName = 'meanstack'; var db = mongoose.createConnection(dbHost, dbName); var Schema = mongoose.Schema, ObjectId = Schema.ObjectId; db.once('open', function callback() { console.log('connected'); }); // schemas var User = new Schema({ name : String }, {collection: 'users'}); // models mongoose.model('User', User); var User = mongoose.model('User'); //exports module.exports.User = User; I receive the following error when I browse to localhost:3000/user/list TypeError: Object { _id: 5398bed35473f98c494168a3 } has no method 'find' at Object.module.exports [as handle] (C:\...\routes\allRoutes.js:8:8) at next_layer (C:\...\node_modules\express\lib\router\route.js:103:13) at Route.dispatch (C:\...\node_modules\express\lib\router\route.js:107:5) at C:\...\node_modules\express\lib\router\index.js:213:24 at Function.proto.process_params (C:\...\node_modules\express\lib\router\index.js:284:12) at next (C:\...\node_modules\express\lib\router\index.js:207:19) at Function.proto.handle (C:\...\node_modules\express\lib\router\index.js:154:3) at Layer.router (C:\...\node_modules\express\lib\router\index.js:24:12) at trim_prefix (C:\...\node_modules\express\lib\router\index.js:255:15) at C:\...\node_modules\express\lib\router\index.js:216:9 Like I said, it's probably something silly that I'm messing up with trying to organize my code since my single file (mongoosetest.js) works as expected. Thanks.

  • jQueryUI dialog width

    - by user35295
    Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });

  • Highlight multiple rows using jQuery

    - by cf_PhillipSenn
    I'm putting together a succinct jQuery matrix because I'm having a hard time navigating around on the jQuery site, and the cheat sheets don't seem to provide me what I want either. Here's how I highlight the rows: $('.eq').hover(function() { $('.eq').toggleClass('highlight'); }); $('.is').hover(function() { $('.is').toggleClass('highlight'); }); Q: How can I write a function that says "toggle everything in the same class as what is being hovered over"? Something like: function toggle(that){ $(that.className).toggleClass('highlight'); }

  • jquery .blur for entire block of HTML

    - by Stacey
    I have an HTML item for a 'drop down menu', structured like this... <li class="ui-dropdown-list" > <a href="#">Right Drop Down Menu</a> <ul> <li><a href="#">Item</a></li> <li><a href="#">Item</a></li> <li><a href="#">Item</a></li> </ul> </li> Using jQuery to make this a dropdown list, with the following code. jQuery.fn.dropdown = function () { var defaults = { button: null, menu: null, visible: false }; var options = $.extend(defaults, options); return this.each(function () { options.button = $(this); options.menu = $(this).find("ul"); // when the parent is clicked, determine whether dropdown needs to occur options.button.click(function () { options.visible ? lift(options.menu) : drop(options.menu); options.visible = !options.visible; }); // drop the menu down so that it can be seen. function drop(e) { options.button.addClass("open"); options.menu.show(); } // lift the menu up, hiding it from view. function lift(e) { options.menu.hide(); options.button.removeClass('open'); } }); }; I am trying to wire it up so that if the user clicks anywhere outside of the menu, it will collapse it. This is proving much more difficult than I anticipated; even trying to use page level events. Any suggestions? The menu itself never really 'receives' focus, so using .blur doesn't seem to be suiting the purpose.

  • simplemodal click events stopped working in IE7

    - by prettynerd
    Here's my code: $('#alertInfo').modal({ close :false, overlayId :'confirmModalOverlay', containerId :'confirmModalContainer', onShow : function(dialog) { dialog.data.find('.message').append(message); dialog.data.find('.yes').click(function(){ if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); dialog.data.find('.close').click(function(){ $.modal.close(); }); } }); Basically, this is a dialogue box which I call to show a warning message that has a "X" button (with class 'close') and an "OK" button (with class 'yes'). The problem occurs in IE7. When I call this dialogue box and use my "X" button to close it everytime, my "X" button does not work anymore on the third time I call it (YES ON THE THIRD TIME!). However, if I use my "OK" button to close the dialogue box, it works fine no matter how many times I call it. I thought I found a workaround by unbinding and binding my click event of the '.close' class, as below: dialog.data.find('.close').unbind('click'); dialog.data.find('.close').bind('click',function(){$.modal.close();}); and it worked!!! unfortunately, however, the problem now occurs in my "OK" button. so, i did the same unbinding and binding the click event of the '.yes' class, as below: dialog.data.find('.yes').unbind('click'); dialog.data.find('.yes').bind('click', function() { if ($.isFunction(callback)) callback.apply(); $.modal.close(); }); BUT NOPE, IT DOES NOT WORK.. please help me.. @ericmmartin, i hope you're online now.. huhu..

  • Processing data from an AJAX request

    - by Josh K
    I have a PHP API I'm working with that outputs everything as JSON. I need to call one of the API methods and parse it out using an AJAX request. I am using jQuery (though it shouldn't matter). When I make the request it errors out with a "parsererror" as the textStatus and a "Syntax Error: invalid label" when I make the request. Simplified code: $.ajax ({ type: "POST", url: "http://mydomain.com/api/get/userlist/"+mid, dataType: "json", dataFilter: function(data, type) { /* Here we assume and pray */ users = eval(data); alert(users[1].id); }, success: function(data, textStatus, XMLHttpRequest) { alert(data.length); // Should be an array, yet is undefined. }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus); alert(errorThrown); }, complete: function(XMLHttpRequest, textStatus) { alert("Done"); } }); If I leave off the eval(data) then everything works fine. Well, except for data still being undefined in success. Note that I'm taking an array of objects in PHP and then passing them out through json_encode. Would that make any difference? There has been no progress made on this. I'm willing to throw more code up if someone believes they can help. Here is the PHP side of things private function _get_user_colors($id) { $u = new User(); $u->get_where(array('id' => $id)); $bar = array(); $bar['user'] = $u->stored; foreach($user->colors as $color) { $bar['colors'][] = $color; } echo(json_encode($bar)); } I have had zero issues using this with other PHP based scripts. I don't know why Javascript would take issue with it.

  • setTimeout is acting weird

    - by mnish
    I am trying to make a simple setTimeout, to make a div tag invisible after 2 seconds. The setTimeout function makes the div invisible but irregularly, sometimes immediately and sometimes after 1 sec, and so on. Here is my code: function beginTimeOut(){ t = setTimeout(function(){hideSubMenu()},2000); } function hideSubMenu(){ var elem; elem = document.getElementById("ul_navlist1"); elem.style.visibility="hidden"; clearTimeout(t); } By the way, t is a global variable. I have tried this too: t = setTimeout("hideSubMenu()",2000); but with the same irregular results.

  • lightbox dynamic image retrieval

    - by GSTAR
    I am constructing a lighbox gallery, currently experimenting with FancyBox (http://fancybox.net) and ColorBox (http://colorpowered.com/colorbox). By default you have to include a link to the large version of the image so that the Lightbox can display it. However, I am wanting to have the image link URLs pointing to a script rather than directly to the image file. So for example, instead of: <a href="mysite/images/myimage.jpg"> I want to do: <a href="mysite/photos/view/abc123"> The above URL points to a function: public function actionPhotos($view) { $photo=Photo::model()->find('name=:name', array(':name'=>$view)); if(!empty($photo)) { $user=$photo->user; $this->renderPartial('_photo', array('user'=>$user, 'photo'=>$photo, true)); } } At some point in the future the function will also update the view count of the image. Now this approach is working to an extent - most images load up but some do not load up (the lightbox gets displayed in a malformed state). I think the reason for this is because it is not processing the function quick enough. For example when I click the "next" button it needs to go to the URL, process the function and retreive/output the response. Does anybody know how I can get this working properly?

  • How can I return to a string address and then assign it to a new string?

    - by Y_Y
    I have 1 function that I want to return the address of an assigned string to the main function and assign an new string pointer with the same address so that the new string will have the contents of the old string. For example: unknown_datatype function() { char *old = "THE STRING"; return old; } int main() { char *snew = ""; snew = function(); return 0; } *unknown_datatype means I don't know that to put there... *How can I approach this without changing anything in the main() method

  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • switch easily between different main()

    - by lezebulon
    I'm using VS2010 I have a project with several headers and one file with the main() function. For testing purposes I'd like to be able to easily another main() function that would instanciate different things than my original main. Is there an easy way to define 2 "main" function, and easily switch between them? The best would be to compile 2 binaries, one that starts at main1() and the other at main2(), or it can be a solution that requires to recompile some files, it doesn't matter

  • Making a Delete and Reply button in Jquery

    - by Branko Ostojic
    this is my second post on the website. Of all other sites i tried, this one gave the most accurate and useful information! I'm in a bit of a trouble with buttons, i have a task to make an inbox and to add a "reply" and "delete" button into every instance of the message. I was indeed wandering if there is a better way to do that than forcing the HTML code into the script, because every message is dynamically generated. Any help and/or suggestions would be very appreciated!(The objects are called from a JSON file). $(document).ready(function(){ $.getJSON('public/js/data.json', function(json){ $.each(json.data, function(i, data){ var output = ''; if(data.from.id != '234' && data.from.name != 'Alan Ford'){ $("#inbox").append( output += '<div class="post">'+ '<div class="h1">'+data.from.name+' - '+data.subject+'</div>'+ //this gives the name of the person who sent the message and the subject '<div class="content">'+data.message_formatted+'</div>'+ //The content of the message //buttons should be squeezed left of the date //this gives the date of the message sent '<div class="time">'+data.date_sent_formatted.formatted+'</div>'+ '</div>' ); }}); }); }); var date_sent=convertToDateTime(); function delete_message(id){ console.log('Delete message with id: '+id); } function reply_message(id, sender){ console.log('Message id: '+id); console.log('Reply to: '+sender); } The complete code in the JSFiddle . Just copy/pasted!

  • How do you make the script wait for the status of an Ajax get request before continuing?

    - by codeninja
    Basically what I'm doing is checking for the existence of an object, if it's not found, the script will try to load the source file using getScript. I only want to check this once though then return true or false to the function that calls fetch() fetch:function(obj){ ... isReady = false; $.getScript(obj.srcFile,function(){ isReady=true; warn("was able to load object "+key); }); return isReady; } but return kicks in before the script loads =/ later the script is loaded but the function returned false. This is the beauty of asynchronous I suppose... What's the best way to handle this... Maybe I could check again at some other point if the object exists? Or maybe there's a better way to do this where I dont have to potentially lock the browser?

  • Creating dynamic icons based on data entered into database from django forms

    - by John Hoke
    So I'm using Django to create a projects page with multiple forms for each project. Let's call them form 1, 2, 3, and 4. Once you create a project you can fill out any of these forms. I want to create "buttons" or links for each one of the forms that would show up on the main page. Now this is the part I need help with: Step 1. I want it so that if you click on a button for a form (say form 1) and none exists for that project yet a pop up would come up saying "This form does not exist yet, are you sure you want to create one?". And if you'd answer yes you would be directed to the form page. Step 2. But if that form does exist, I don't want any pop up to open and I want the link to take the user directly to that page. Step 3. My next problem is this. These forms are in order, so if you didn't create form 1 but created form 2, I don't want to give the user access to form 1. So in this scenario, if you click on form 1 I want a pop up to open and say "This form can no longer be created", and the link wouldn't function anymore. Basically the button will have 3 function. First it should look at the database and if data for that specific form exists it should do "Step 2", if data for that form and the proceeding forms don't exist it should do "Step 1", and if data for that form doesn't exist but data for proceeding form's does exist is should do "Step 3". Is this possible? Please help as I need to find a solution to this soon. Any help would be highly appreciated. Thank you

  • Dynamic jQuery dialog after data append w/o reloading page. Possible?

    - by Arun
    Howdy, So I have a page with an enormous table in a CRUD interface of sorts. Each link within a span calls a jQuery UI Dialog Form which fetches it's content from another page. When the action taking place (in this case, a creation) has completed, it appends the resulting new data to the table and forces a resort of the table. This all happens within the JS and the DOM. The problem with this, is that the new table row's CRUD links don't actually trigger the dialog form creation as all the original links in spans are only scanned on document.ready and since I'm not reloading the page, the new links cannot be seen. Code is as follows: $(document).ready(function() { var $loading = $('<img src="/images/loading.gif" alt="Loading">'); $('span a').each(function() { var $dialog = $('<div></div>') .append($loading.clone()); var $link = $(this).one('click', function() { // Dialog Stuff success: function(data) { $('#studies tbody').append( '<tr>' + '<td><span><a href="./?action=update&study=' + data.study_id + '" title="Update Study">Update</a></span></td>' + '</tr>' ); fdTableSort.init(#studies); // This re-sorts the table. $(this).dialog('close'); } $link.click(function() { $dialog.dialog('open'); return false; }); return false; }); }); }); Basically, my question is if there is any way in which to trigger a jQuery re-evaluation of the pages links without forcing me to do a browser page refresh?

  • JQuery, Load() contents with plugins

    - by Galas
    I know this is not a completely new question, but none of the answers solved my problem... I have built a little menu that uses load() to load image galleries (as external html files) into a specified div ("content"). The said galleries make use of a JQuery plugin (SlideJS). Now I know that load() does not work for script tags and that I need to use $.getscript in the callback function in order to run the scripts, but it does not work. I have two .js files that need to be loaded: one is the plugin itself and another one is a smaller script with a preloader and the animations for the captions. I can't seem to merge them together; if I put them into the same document, the script won't run. So I tried just using $.getscript to load the two files. I tried using two callbacks as suggested in other answer (I know it's not ideal...): $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ $.getScript("js/slide.js", function (){ $.getScript("js/slidepage.js"); }); }); }); and I tried a variable (read about it in some other faq, not sure if the syntax is correct) $("#proposal").click(function(){ $(this).addClass('selected'); $("a:not(:#proposal)").removeClass('selected'); $("#content").load("works/proposal/proposal.html", function(){ var scripts = ['js/slide.js','js/slidepage.js']; $.getScript(scripts); }); }); So none of these work. What am I doing wrong? I'm just starting on jquery and my js knowledge is very limited. Should I just merge the two .js files together using minify or something? One of them is already minified, but I've tried with a non-minified version and it does not work either. Can anyone suggest any other solution around this problem? I thought of just having the div embedded in the main document and just showing it on click, but I'll have at least 4 galleries with about 8 to 10 images each... its a lot of images to load in the main page, so I don't think its the best way. if you need me to post any more code, please ask! Thanks in advance for all your help!

  • How can I use "IF statements" in a postgres trigger
