  • Adding Categories to my Articles in my Rails app (Small Help)

    - by user214038
    I'm currently building a semi-small ruby app for a project. The problem I'm currently facing is the following: I want to be Able to fit the Article into the Categories. I've already accomplish this by having two models. An article model with a foreign key of category_id and my Category model with the name of the category. With a has_one and belogs_to relationship. (We're assuming you can only fit an article into one category). Here's the piece of code. This is the new method, where i create a new article and load up all the categories. def new @article = Article.new @categories = Category.find(:all) end The problem comes when i try to get the category from a combo box in order to insert it along with the article. This is the combo box code : f.select(:category_id,@categories) And this is the create method: def create @category = Category.find(params[:id]) @article = @category.articles.new(params[:article]) if @article.save flash[:notice] = "Article Submitted Sucessfully" redirect_to user_path else render :action = 'new' end end I believe that the problem i have is in this line when i try to load up the selected category "@category = Category.find(params[:id])" because whenever i hardcode the this line into @category = Category.find(1) It Works perfectly

  • How to use the FindControl function to find a dynamically generated control?

    - by Abe Miessler
    I have a PlaceHolder control inside of a ListView that I am using to render controls from my code behind. The code below adds the controls: TextBox tb = new TextBox(); tb.Text = quest.Value; tb.ID = quest.ShortName.Replace(" ", ""); ((PlaceHolder)e.Item.FindControl("ph_QuestionInput")).Controls.Add(tb); I am using the following code to retrieve the values that have been entered into the TextBox: foreach (ListViewDataItem di in lv_Questions.Items) { int QuestionId = Convert.ToInt32(((HiddenField)di.FindControl("hf_QuestionId")).Value); Question quest = dc.Questions.Single(q => q.QuestionId == QuestionId); TextBox tb = ((TextBox)di.FindControl(quest.ShortName.Replace(" ",""))); //tb is always null! } But it never finds the control. I've looked at the source code for the page and the control i want has the id: ctl00_cphContentMiddle_lv_Questions_ctrl0_Numberofacres For some reason when I look at the controls in the ListViewDataItem it has the ClientID: ctl00_cphContentMiddle_lv_Questions_ctrl0_ctl00 Why would it be changing Numberofacres to ctl00? Is there any way to work around this? UPDATE: Just to clarify, I am databinding my ListView in the Page_Init event. I then create the controls in the ItemBound event for my ListView. But based on what @Womp and MSDN are saying the controls won't actually be created until after the Load event (which is after the Page_Init event) and therefore are not in ViewState? Does this sound correct? If so am I just SOL when it comes to retrieving the values in my dynamic controls from my OnClick event?

  • How do I update the UI during an event using ASP.NET?

    - by Phil Hale
    I'm a bit stuck with a problem. I feel like the solution should be fairly straight forward but I'm completely out of ideas for some reason. Here's the problem. I've got a user control with a couple of buttons. Think of them as 'On' and 'Off'. When either button is clicked an async method is called. If the method is successful an event is fired. Within the event I want to update the enabled property of the two buttons so that only a single button is clickable at any one time. The problem is that any changes I make to the properties are not shown on screen because the postback is already complete. I tried wrapping the buttons in an UpdatePanel but I get an "Update method can only be called on UpdatePanel with ID 'xxxx' before Render' error. I understand why the problem occurs but I can't think of a solution. Help! Ideally what I'd like to do is simply call a method within the event that will update the UI, but I don't know if that's possible.

  • PHP static objects giving a fatal error

    - by Webbo
    I have the following PHP code; <?php component_customer_init(); component_customer_go(); function component_customer_init() { $customer = Customer::getInstance(); $customer->set(1); } function component_customer_go() { $customer = Customer::getInstance(); $customer->get(); } class Customer { public $id; static $class = false; static function getInstance() { if(self::$class == false) { self::$class = new Customer; } else { return self::$class; } } public function set($id) { $this->id = $id; } public function get() { print $this->id; } } ?> I get the following error; Fatal error: Call to a member function set() on a non-object in ....../classes/customer.php on line 9 Can anyone tell me why I get this error? I know this code might look strange, but it's based on a component system that I'm writing for a CMS. The aim is to be able to replace HTML tags in the template e.g.; <!-- component:customer-login --> with; <?php component_customer_login(); ?> I also need to call pre-render methods of the "Customer" class to validate forms before output is made etc. If anyone can think of a better way, please let me know but in the first instance, I'd like to know why I get the "Fatal error" mentioned above. Cheers

  • How can I spec out an authlogic sessions controller using using a stub?

    - by Dave
    I want to test my User Session Controller testing that a user session is first built then saved. My UserSession class looks like this: class UserSession < Authlogic::Session::Base end The create method of my UserSessionsController looks like this: def create @user_session = UserSession.new(params[:user_session]) if @user_session.save flash[:notice] = "Successfully logged in." redirect_back_or_default administer_home_page_url else render :new end end and my controller spec looks like this: describe UserSessionsController do it "should build a new user session" do UserSession.stub!(:new).with(:email, :password) UserSession.should_receive(:new).with(:email => "[email protected]", :password => "foobar") post :create, :user_session => { :email => "[email protected]", :password => "foobar" } end end I stub out the new method but I still get the following error when I run the test: Spec::Mocks::MockExpectationError in 'UserSessionsController should build a new user session' <UserSession (class)> received :new with unexpected arguments expected: ({:password=>"foobar", :email=>"[email protected]"}) got: ({:priority_record=>nil}, nil) It's although the new method is being called on UserSession before my controller code is getting called. Calling activate_authlogic makes no difference.

  • Adding a variable href attribute to a hyperlink using XSLT

    - by Pete
    I need to create links using dynamic values for both the URL and the anchor text. I have column called URL, which contains URL's, i.e., http://stackoverflow.com, and I have a column called Title, which contains the text for the anchor, i.e., This Great Site. I figure maybe all I need to do is nest this tags, along with a little HTML to get my desired result: <a href="> <xsl:value-of select="@URL">"> <xsl:value-of select="@Title"/> </xsl:value-of> </a> In my head, this would render: <a href=" http://stackoverflow.com"> This Great Site </a> I know there's more to it, but I haven't been able to clearly understand what more I need. I think this issue has been addressed before, but not in a way I could understand it. I'd be more than happy to improve the question's title to help noobs like myself find this item, and hopefully an answer. Any help is greatly appreciated.

  • Black Corners On Grouped UITableViewCells Only After Navigation Pops

    - by coneybeare
    I am not graphics expert but I somehow managed to make some good looking custom grouped UITableViewCells by setting the background view to a backgroundView with some CG code. In all SDK's up to 3.1.3 (maybe 3.2... I haven't tested on the iPad) this was working great, but I think a more recent SDK has introduced a change in the way graphics are cached offscreen. Upon first render, everything is great: The drawing is fine and the corners are transparent. If I push a couple of view controllers on the navigation stack and come back, there are now black corners that appear in the views: BEFORE && AFTER I have tons of code, most of which is written up here. I have tried tweaking to the best of my ability, looking at the docs for applicable changes, but after at least 8 hours in I still cannot find what might cause this. I have tried setting every view I can think of to be backgroundColor=clearColor and opaque=NO What else am I missing? Any debugging tips? UPDATE: I have some debug code in viewDidAppear that prints the backgroundColor and class description of all the subviews. - (void)debugView:(UIView *)view { DebugLog(@"%@ - %@", view.backgroundColor, [[view class] description]); for (UIView* child in view.subviews) { [self debugView:child]; } } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [DownloadController.networkQueue setSuspended:NO]; for (TTTableViewCell *cell in [self.tableView visibleCells]) { [cell debugView:cell]; } } With this code, I inspect the backgroundColor settings of the cell views on first load, when it is fine, and then again after coming back. There are some differences, but all the colors are still set to be clear. This leads me to believe the issue is underneath the UITableViewCell. UPDATE 2: I have created a simple sample application to highlight the problem here

  • Can CSS change the apparent sequence of elements, e.g. using float or position?

    - by ChrisW
    Edit: answer to this question is easy, a simple example of float left and float right. I'd like to float some annotations to the left of a topic using HTML and CSS, for example the 'status' and 'author' annotations shown in the following mockup/image: For semantic reasons, perhaps: I prefer to use CSS instead of a table-based layout In the HTML, the status should appear after the corresponding heading For example: <h1>This is a section title</h1> <div class="status">approved</div> <div class="author">chris</div> <p>This is some text. Lorem ipsum.</p> <p>Lorem ipsum.</p> <h1>Different section title</h1> <div class="status">rejected</div> <p>Lorem ipsum.</p> I'd like the annotations to be after the heading in the HTML, because everything associated with (i.e. the contents of) a topic is usually whatever is after the topic's heading. However I'd like the annotations to be displayed before (to the left of) the heading, as illustrated above. Is this possible? What is the most semantic HTML, and corresponding CSS, that will render as shown above? Would you recommend a table-based layout instead? Even if that means putting the headings in a table cell? It may not be possible; this answer suggests it isn't possible ... but I don't know CSS well enough to say that for sure.

  • Selenium Webdriver Java - looking for alternatives for Actions and Robot when performing drag-and-drop

    - by Ja-ke Alconcel
    I first tried Actions class and the drag-and-drop does work on different elements, however it was unable to locate the a specific draggable element on it's exact screen/webpage position. Here's the code I've used: Point loc = driver.findElement(By.id("thiselement")).getLocation(); System.out.println(loc); WebElement drag = driver.findElement(By.id("thiselement")); Actions test = new Actions(driver); test.dragAndDropBy(drag, 0, 60).build().perform(); I checked the element with it's pixel location and it prints (837, -52), which was somewhere on top of the webpage and was pixels away from the actual element. Then I tried using the Robot class and works perfectly fine on my script, but can only provide constant successful runs on a single test machine, running it with a different machine with different screen resolution and screen size will render the script to fail due to the dependency of Robot on the pixel location of the element. The sample code of the Robot script I'm using: Robot dragAndDrop = new Robot(); dragAndDrop.mouseMove(945, 166); //actual pixel location of the draggable element dragAndDrop.mousePress(InputEvent.BUTTON1_MASK); sleep(3000); dragAndDrop.mouseMove(945, 226); dragAndDrop.mouseRelease(InputEvent.BUTTON1_MASK); sleep(3000); Is there any alternative for Actions and Robot to automate drag-and-drop? Or maybe a help on working the script to work on Actions as I really can't use Robot. Thanks in advance.

  • .NET MVC: How to fix Visual Studio's lack of awareness of CSS classes in partial views?

    - by Mega Matt
    Hi all, This has been sort of an annoyance for me for a while. I make pretty heavy use of partial views in MVC, and am using Visual Studio 2008 to develop. The problem is that when I give html elements a class in a partial view (<div class="someClass">), it will underline them in green like it doesn't know what they are. I realize this is because I'm in a partial view, and haven't put link tags anywhere in that file for it to know where the CSS is (the link tags are in the main view that renders the partial view). The CSS still works fine on my site because the browser will render all views as one long html page anyway, but it's really annoying to look through my partial views and see all of my classes underlined in green. Is there a way that I can still tell Visual Studio that those classes exist somewhere, from the partial view? I figured there has to be a way to let it know, but am not sure what it is. Maybe a way to import the stylesheets from the parent view? Thanks for your help.

  • Image in table cell doesn't scale down: using ie8/7

    - by monks1975
    Can anyone help me troubleshoot my website? http://www.andrewstonyer.co.uk/test/ My problem: On IE8/7 if you click on a thumbnail (only 'Pulse' and 'Time Within The Hour' are wired in right now) an overlay appears with detail of that piece. What should happen, and does in Gecko/Webkit, is that the overlay contains a table with a heading, a scaled, centered image, and a nav menu. There is a toggle for text, which pushes up the image cell and makes the image smaller, keeping proportion. I know the overlay looks like ass right now- those are just placeholder colours :) On IE, the image doesn't fit perfectly in the table cell, which means that everything is pushed down outside the window. I can't see the nav menu. It appears to render the image at actual pixel size (in the CSS, the img class element is set to 100% height). The text cell is toggled with jquery, when toggled on in IE, it doesn't appear to 'squeeze' the above cell, which is what I want to happen. Could any experts help? Regards, Jon

  • Rails: Rendered JS file doesn't execute using UJS

    - by Hassinus
    I would like to display a Rails edit form using JS instead of redirecting with HTML. To do this, I use UJS for the edit link: <%= link_to "Edit user info", edit_user_path(1), :remote => true %> Then, the "edit" action of User controller is like this (simplified version): controllers/users_controller.rb: def edit # Step 1: Get the edit HTML form @html = render_to_string(:template => "users/edit.html") # Step 2: Use JS to display the form in the correct place render "users/edit.js" end As you may guess, I have two views: The html version of "edit" action which contains the form in HTML format. Let's consider a test version: views/users/edit.html.erb: <h1>This is just a test</h1> The js version that will display the form in the correct place, using jQuery for example. Again, for test purpose, let's just popup the html text: views/users/edit.js.erb: alert("<%= @html %>"); The problem is that nothing is executed (no popup) Using the inspector (from Chrome web browser), I get the response as text format: alert("<h1>This is just a test</h1>"); Do you have any idea? Why do the rendered JS is not executed? Thanks in advance.

  • [Rails] checkbox to update attribute

    - by Jeff
    [Updated a bit] I have a Task model that has a :completed boolean attribute. If I click on it I want it to execute the 'finish' method. The main problem is that I am displays a series of checkboxes in a list and subsequent checkboxes after the first one are ignored. The method is never called for the given task/checkbox combo. I have this chunk of code in my view: <% current_user.tasks.each do |t|%> <% if t.completed == false %> <%= check_box_tag :completed, true, checked = false %> <%= observe_field :completed, :url => { :controller => 'tasks', :action => :finish , :id => t.id }, :frequency => 0.25, :update => :completed, :with => true %> and my finish method looks like this: def finish @task = Task.find(params[:id]) new = {:completed => true} @task.update_attributes(new) render :update do |page| page.replace_html "taskListing", :partial => 'home/task_listing' end

  • Passing list of values to django view via jQuery ajax call

    - by finspin
    I'm trying to pass a list of numeric values (ids) from one web page to another with jQuery ajax call. I can't figure out how to pass and read all the values in the list. I can successfully post and read 1 value but not multiple values. Here is what I have so far: jQuery: var postUrl = "http://localhost:8000/ingredients/"; $('li').click(function(){ values = [1, 2]; $.ajax({ url: postUrl, type: 'POST', data: {'terid': values}, traditional: true, dataType: 'html', success: function(result){ $('#ingredients').append(result); } }); }); /ingredients/ view: def ingredients(request): if request.is_ajax(): ourid = request.POST.get('terid', False) ingredients = Ingredience.objects.filter(food__id__in=ourid) t = get_template('ingredients.html') html = t.render(Context({'ingredients': ingredients,})) return HttpResponse(html) else: html = '<p>This is not ajax</p>' return HttpResponse(html) With Firebug I can see that POST contains both ids but probably in the wrong format (terid=1&terid=2). So my ingredients view picks up only terid=2. What am I doing wrong? EDIT: To clarify, I need the ourid variable pass values [1, 2] to the filter in the ingredients view.

  • Want to mimic iphone address book search (In terms of interface & interaction)

    - by mr-sk
    Hi, When you do a search in the address book the flow is: 1) Select the search bar 2) The right most transparent a-z index is removed 3) A transparent black window is placed over the current UITableView 4) When you begin typing, a new UITableView is loaded with no data 5) The UITableView is populated with data as you type. 6) If you select an item you are brought to it 7) If you cancel the search you return to the main UITalbeView My first real question is, how do I load a new UITableView when a user begins searching? Is it as easy as popping a new view on the stack? It would then be a seperate .m/.h file with its own implementation? The second question is how do you remove the right most index? Or just that just go away when you render the new (blank) UITableView? I've gotten search working, but mine does it in the same UITableView, which when you start contains like 2K results, is grouped (A results under A Heading, etc) and has a right most index. I'd be happy leaving the results in the table, if I could; 1) Remove the rightmost a-z index 2) Drop the table groupings 3) Tell the view I only have N search results so it will build the scroll bar correctly. Thanks for your input; sk

  • Rendering maps from raw SVG data in Java

    - by Lunikon
    In an application of mine I have to display locations and great circle paths in a map which is rendered to PNG and then displayed on the web. For this I simply use a world map (NASA's Blue Marbel in fact) scaled to various "zoom levels" as base image and only display the a part of it matching the final image size and fitting all items to be displayed. Straight forward so far. Now I came across Wikipedia's awesome blank SVG maps which contain all the country codes for easy reference and I was wondering whether it was possible to use those to have more customized colors and to highliht countries etc. So I did a bit of googling and was looking for Java libraries which would enable me to load the blank SVG map to memory allows for easy reference/selection of certain paths do manipulations of coloring, stroke widths etc render to a buffered image as the background for the great-circle paths/nodes What I came across quite often was Batik, but it looks like a really heavy framework and I'm not quite sure whether it is what I'm looking for. I have recently played around with Raphaël a bit and I like the way it handles working with vector graphics in code. If the Java framework for my purpose would feature a similar interface, that would be a nice-to-have. Any recommendations what toolset would be approriate for my purposes?

  • DELETE causing a redirect loop?

    - by robocode
    I have an express app with a postgres backend where a user can add/delete recipes, and each time they do so they get an updated list of recipes. Adding a recipe is fine, but when I delete one it seems to get stuck in a redirect loop. In app.js I have router.get('/delete/:d', delRec.deleteRecipe); which calls the following code exports.deleteRecipe = function(req, res){ pg.connect(conString, function(err, client) { client.query('DELETE FROM recipes WHERE recipe_name = ', [req.params.d], function(err, result) { if(err) { return console.error('error running query', err); } else if (result) { pg.end(); console.log('deleting'); } }); }); res.redirect('recipes'); }; If I try delete a recipe, console.log('deleting') produces deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting deleting The recipes route is below (sorry that it's so convoluted) router.get('/recipes', function(req, res) { pg.connect(conString, function(err, client) { if(err) { return console.error('could not connect to postgres', err); } client.query('SELECT * FROM recipes', function(err, result) { if(err) { return console.error('error running query', err); } recipes = result.rows; for(var d in recipes) { if (recipes.hasOwnProperty(d)) { recipeList[d] = recipes[d].recipe_name; } } res.render('recipes', {recipes: recipes, recipeList: recipeList}); }); }); });

  • MVC3 View For Loop values initialization

    - by Ryan
    So I have a for loop in my View that is supposed to render out the input boxes. Now inside these input boxes I want to put lables that disappear when you click on them. This is all simple. Now it's probably because my brain was wired for php first, and it has been difficult to get it to think in lambdas and object orientation, but I can't figure out how to do this: @{ for (int i = 0; i < 3; i++) { <div class="editor-label grid_2">User</div> Model.Users[i].UserFirstName = "First Name"; Model.Users[i].UserLastName = "Last Name"; Model.Users[i].UserEmailAddress = "Email Address"; <div class="grid_10"> @Html.TextBoxFor(m => Model.Users[i].UserFirstName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserLastName, new { @class = "user-input" }) @Html.TextBoxFor(m => Model.Users[i].UserEmailAddress, new { @class = "user-input-long" }) @Html.CheckBoxFor(m => Model.Users[i].IsUserAdmin) <span>&nbsp;admin?</span> </div> <div class="clear"> </div> } } And initialize the values for the users. And you're probably thinking "Of course that won't work. You're going to get a Null Reference Exception", and you would be correct. I might need to initialize them somewhere else and I don't realize it but I'm just not sure. I've tried the [DefaultValue("First Name")] route and that doesn't work. I'm probably thinking about this wrong, but my brain is already shot from trying to figure out how to wire up these events to the controller, so any help would be appreciated!

    I'm checking to see if anyone has written an MVC extension for Html.ActionLink that you can pass in Post parameters like such: <% Html.ActionLink("Click me", "Index", "Home", new { MyRouteValue = "123" }, null, new { postParam1 = "a", postParam2 = "b" }); %> That would render the link like normal but having an onClick event that submits an also rendered form with an Action url for the Action, Controller, and Route Values with additional hidden inputs from the Post Parameters like such: <a href="#" onClick="$('#theform').submit(); return false;">Click me</a> <form id="theform" action="/Home/Index/123" method="post"> <input type="hidden" name="postParam1" value="a"> <input type="hidden" name="postParam2" value="b"> </form> I'm looking to redirect users to various pages with potentially a lot of data. Not only from page to page, but from email to page also. This would be highly reusable and I think would clean up a lot of code, and would save a bunch of time writing this if its already floating around out there. I hate recreating the wheel when I don't have to. Thanks!

  • Perl regex which grabs ALL double letter occurances in a line

    - by phileas fogg
    Hi all, still plugging away at teaching myself Perl. I'm trying to write some code that will count the lines of a file that contain double letters and then place parentheses around those double letters. Now what I've come up with will find the first ocurrance of double letters, but not any other ones. For instance, if the line is: Amp, James Watt, Bob Transformer, etc. These pioneers conducted many My code will render this: 19 Amp, James Wa(tt), Bob Transformer, etc. These pioneers conducted many The "19" is the count (of lines containing double letters) and it gets the "tt" of "Watt" but misses the "ee" in "pioneers". Below is my code: $file = '/path/to/file/electricity.txt'; open(FH, $file) || die "Cannot open the file\n"; my $counter=0; while (<FH>) { chomp(); if (/(\w)\1/) { $counter += 1; s/$&/\($&\)/g; print "\n\n$counter $_\n\n"; } else { print "$_\n"; } } close(FH); What am I overlooking? TIA!

  • Chrome renders button links completely screwed up when placed inside a paragraph

    - by Ferdy
    I am fairly proficient in CSS but now I am running into a very strange rendering issue in Google Chrome 9. I am trying to create some fancy looking link buttons (basically heavily styled anchors). Here is some example markup: <a href="" class="button"> <figure class="sprite icon icon_back"></figure> Link button with icon</a> This markup may look a litte strange to you, there's a few things you should know: I am using HTML5's figure class to include an icon as part of the button. I have the proper reset CSS applied and Chrome can render this tag for sure. Instead of actually pointing to an image I am applying CSS classes to the figure element. Within the CSS I am using the spriting technique to show the correct portion of a single large sprite image. All of this is working fine in Firefox, and actually also in Chrome. The correct rendering can be seen in the following image: It renders like that in both Firefox and Chrome. Here comes the problem, if I place such a button within paragraph tags <p></p> this is what happens in Chrome only: Notice how the button is ripped apart? Only in Chrome and only when placed inside a paragraph. It gets even stranger: this only happens for the first button inside the paragraph, if I would place three buttons inside a paragraph, only the 1st one is screwed up. Your first question would probably be about the CSS. It is rather verbose so hereby a temporary link to the page in question: Edit: link to live page removed, was only temporary for problem inspection.

  • Have something loaded only when JList item is visibile

    - by elvencode
    Hello, i'm implementing a Jlist populated with a lot of elements. Each element corresponds to a image so i'd like to show a resized preview of them inside each row of the list. I've implemented a custom ImageCellRenderer extending the Jlabel and on getListCellRendererComponent i create the thumbnail if there'snt any for that element. Each row corresponds to a Page class where i store the path of the image and the icon applied to the JLabel. Each Page object is put inside a DefaultListModel to populate the JList. The render code is something like this: public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { Page page = (Page) value; if (page.getImgIcon() == null) { System.out.println(String.format("Creating thumbnail of %s", page.getImgFilename())); ImageIcon icon = new ImageIcon(page.getImgFilename()); int thumb_width = icon.getIconWidth() > icon.getIconHeight() ? 128 : ((icon.getIconWidth() * 128) / icon.getIconHeight()); int thumb_height = icon.getIconHeight() > icon.getIconWidth() ? 128 : ((icon.getIconHeight() * 128) / icon.getIconWidth()); icon.setImage(getScaledImage(icon.getImage(), thumb_width, thumb_height)); page.setImgIcon(icon); } setIcon(page.getImgIcon()); } I was thinking that only a certain item is visibile in the List the cell renderer is called but i'm seeing that all the thumnails are created when i add the Page object to the list model. I've tried to load the items and after set the model in the JList or set the model first and after starting appending the items but the results are the same. Is there any way to load the data only when necessary or do i need to create a custom control like a JScrollPanel with stacked items inside where i check myself the visibility of each elements? Thanks
