  • How do I produce an external URL as part of a replace_html call in Ruby on Rails?

    - by vlasits
    Basically, I am attempting to render an external website (the url of which is stored in the database) into a page in my Ruby on Rails app. I have a field in my model 'search' called 'search' that contains web addresses with the form 'www.example.com' or 'example.com'. I am trying to use a link_to_function call with replace_html to replace the 'maincontent' div with an iframe tag using the value of 'search' in the current instance as the src for the tag. My current attempt is the very ugly code below. I'd be grateful for either of the following types of responses: How can I rewrite the concatenation string to work correctly? How can I get the same effect (replacing the current content of the "mainContent" div with an iframe tag using a different method? (I had to modify the code before to remove the < from the iframe) link_to_function h(search.title) do |page| page.replace_html 'mainContent', 'iframe id="embedded" src="http://" + #{search.search} />' end

  • Thread Jobs in Java

    - by Bragaadeesh
    Hi, I want to spawn 200 threads simultaneously in Java. What I'm doing right now is running into a loop and creating 200 threads and starting them. After these 200 gets completed, I want to spawn another 200 set of threads and so on. The gist here is that the first 200 threads I spawned need to be FINISHED before spawning the next set. I tried the code below, but its not working for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } Note: I have intentionally put the for loop Twice, but the desired effect I intend is not happening simply because the second for loop is executed before the first set of threads end their execution. Please advise

  • get foreign key objects in a single query - Django

    - by John
    Hi I have 2 models in my django code: class ModelA(models.Model): name = models.CharField(max_length=255) description = models.CharField(max_length=255) created_by = models.ForeignKey(User) class ModelB(models.Model): category = models.CharField(max_length=255) modela_link = models.ForeignKey(ModelA, 'modelb_link') functions = models.CharField(max_length=255) created_by = models.ForeignKey(User) Say ModelA has 100 records, all of which may or may not have links to ModelB Now say I want to get a list of every ModelA record along with the data from ModelB I would do: list_a = ModelA.objects.all() Then to get the data for ModelB I would have to do for i in list_a: i.additional_data = i.modelb_link.all() However this runs a query on every instance of i. Thus making 101 queries to run. Is there any way of running this all in just 1 query. Or at least less than the 101 queries. I've tried putting in ModelA.objects.select_related().all() but this didn't seem to have any effect. Thanks

    $(document).ready(function () { $('#keywordframe').contents().find("#step12").html(''); $('#keywordframe').contents().find("#step12").html('11'); $('#keywordframe').contents().find("#step13").html(''); $('#keywordframe').contents().find("#step13").html('12'); $('#keywordframe').contents().find("#step14").html(''); $('#keywordframe').contents().find("#step14").html('13'); $('#keywordframe').contents().find("#step15").html(''); $('#keywordframe').contents().find("#step15").html('14'); }); I try to use the above code to change the content in an iframe, but it is not working. Unless I put alert(''); on top of $('#keywordframe').contents().find("#step12").html(''); if just will take effect. What is the reason for that, anyone could help?

  • the correct actionscript to find if object already exists

    - by touB
    I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea if(theRect == undefined){ Alert.show("creating"); var theRect:Rect = new Rect(); //then set properties addElement(theRect); //then add it using addElement because addChild() does not work } else { Alert.show("updating"); //no need to create it since it's already been created //just access and change the properties } I tried several ways and combinations for the if conditional check: if(theRect == undefined){ if(theRect == null){ declaring and not declaring `var theRect:Rect;` before the if check declaring and instantiating to null before the if check `var theRect:Rect = null;` but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?

  • Flex: How to create a floating notification message of sorts for a custom component?

    - by aberrant80
    I have a custom TextInput-based component for date and time with certain restrictions on what's considered "within range". But it's still fine to insert dates that are outside the range. When a user types in a date, on valueCommit, I'd like to be able to display a hovering notification to the user, to inform/warn them that the date is outside the accepted range. I'm thinking of notifications ala the Validators, but I'd rather not use the Validator mechanism because it's really not validation, just notification. Something like a tooltip, but it will only appear if the user changed the value. Maybe an effect of some sort? If anyone has any ideas or if anyone has done something like this, I'm all ears!

  • how does [<Literal>] differ from other constants in F#

    - by Mitzh
    I am a bit confused by the Literal keyword and why it is necessary in F#. Reading the docs, it sounds to me that [<Literal>] is used to define a constant, however I am a bit confused how this constant differs from all other constants in F#.. Values that are intended to be constants can be marked with the Literal attribute. This attribute has the effect of causing a value to be compiled as a constant. When I think of a constant, I think of something which is immutable.... let x = "a" + "b" //this is a immutable value, its value is constant [<Literal>] let y = "a" + "b" //this is also a immutable value, but why is this a special constant? Is it because the 'normal' F# values are evaluated lazily and the [<Literal>] is not evaluated lazily..? is that what they mean with 'compiled as constant'..? or is there something else to it?

  • IQueryable<> dynamic ordering/filtering with GetValue fails

    - by MyNameIsJob
    I'm attempting to filter results from a database using Entity Framework CTP5. Here is my current method. IQueryable<Form> Forms = DataContext.CreateFormContext().Forms; foreach(string header in Headers) { Forms = Forms.Where(f => f.GetType() .GetProperty(header) .GetValue(f, null) .ToString() .IndexOf(filter, StringComparison.InvariantCultureIgnoreCase) >= 0); } However, I found that GetValue doesn't work using Entity Framework. It does when the type if IEnumerable< but not IQueryable< Is there an alternative I can use to produce the same effect?

  • Extreamely fast way to clone the values of an array into a second array?

    - by George
    I am currently working on an application that is responsible for calculating random permutations of a multidemensional array. Currently the bulk of the time in the application is spent copying the array in each iteration (1 million iterations total). On my current system, the entire process takes 50 seconds to complete, 39 of those seconds spent cloning the array. My array cloning routine is the following: public static int[][] CopyArray(this int[][] source) { int[][] destination = new int[source.Length][]; // For each Row for (int y = 0; y < source.Length; y++) { // Initialize Array destination[y] = new int[source[y].Length]; // For each Column for (int x = 0; x < destination[y].Length; x++) { destination[y][x] = source[y][x]; } } return destination; } Is there any way, safe or unsafe, to achieve the same effect as above, much faster?

  • Detecting and reloading updated application parameters at runtime

    - by VeeKayBee
    I am working on an ASP.NET web application(using .NET 4.5 and C#).The application deals with lot of units (for measuring like KG,Litre,KM etc). So based on the selected unit we have to implement some allowed range.This values can be configured without much effort. We identified two solutions for this Keeping a configuration xml. Suppose the values in xml, does it requires an iisreset or any other thing which can take the site down for some time, if we are changing the xml file to change some validation. Keeping in Db, then use SQL dependency caching. So an update to DB can reflect the caching values.SO i believe if we change the values, it will update the cache. How much complex is this and does it effect the performance ? It will be great helpful, if we have some other method to achieve this. Thanks in advance.

  • jquery/ajax load new content when available

    - by Tim
    I know this is quite a vague question -- sorry about that. If I have a forum, shoutbox or something similar where users enter and submit data, running on PHP and MySQL, what is the best way to have the newly submitted content automatically display on the page for all users when it is submitted? Much like a live newsfeed, if you like... The effect sort-of works here at stackoverflow, when you are answering a question you are told when new answer is submitted. I want to test for newly submitted content and then display it automatically. Any suggestions? Many thanks :)

  • vb.net press/release keys

    - by Cyclone
    How can you simulate keypresses and releases? I know you can essentially hit a key with Sendkeys.SendWait, but how can your code press and hold q, for example? Any help is much appreciated! Everything I find keeps pointing me at sendkeys, which is not correct. I essentially wish to be able to call something like press("q") and release("q"). The effect would be the same as physically holding them down. Thanks for your help!

  • Make the text of a disabled textbox easier to see

    - by Vaccano
    I have a text box that when it is disabled the text in it is gray and kind of dithered. (This is the standard functionality.) Is there a way to make this easier to see? I have tried this: txtBoxNumber.Enabled = false; txtBoxNumber.ForeColor = Color.Black; and that has no effect. NOTE: This is a .net Compact Framework app, but I am not tagging the question with CF because I think it is the same for normal .net.

  • Will the next iPhone Simulator be able to simulate the high resolution of iPhone 4?

    - by dontWatchMyProfile
    As a follow-up to this question, the next one is: Will we be able to simulate our interfaces how they look on the new high resolution display, even without owning an iPhone 4? I guess that there is a formula that we can use to calculate the exact needed distance between our monitors and our eyes, to achieve the exact same visual effect of the Retina Display. This would help a lot to get things right. The first thing we need is an high resolution iPhone Simulator. I can't get any sleep until I know.

  • Getting a divs z-index to overlap a div with absolute positioning

    - by Paul Herron
    Does anyone know how I could get the logo at the top of my page to appear on top of the curtains. http://nuigums.tumblr.com/ The logo is within a section tag along with the rest of the content with a z-index of 2, which is required to get the footer reveal effect I want. The curtain has a z-index of 3. I tried setting the z-index of the logo div to 4 but I presume the fact that the sections styling overrides that? I would like the logo to scroll with the content of the page also. Thanks. :)

  • jQuery slideDown() not animating (jquery-rails 3.0.4; jquery-ui-rails (4.0.5)

    - by Michael Guren
    I am following along in the latest Agile Web Development with Rails 4 book. In Chapter 11 (AJAX), the book instructs us to use the following code in the "create.js.erb" file: if ($('#cart tr').length == 1) { $('#cart').show('blind', 1000); } This code causes the #cart div to jump down without any content. After 1 second it appears. There is no sliding effect. I tried using slideDown(); as well, but the div just appears immediately. Out of curiosity, I tried slideUp(); when the div was visible. Voila. The div slid up. This appears to be a jQuery bug and wondered if anyone else has experienced this, or has any suggestions for me. Thanks.

  • Wrapping an array of elements.

    - by fivetwentysix
    I'm trying to write an unobtrusive script and I don't want to add any html that's not needed unless javascript is enabled. Using MooTools 1.2.4, is it possible to wrap a an array of elements with say for example: tags? Desired effect: Before: <p>Something</p> <p>Something1</p> <p>Something2</p> <p>Something3</p> Wishful thinking javascript code: $$('p').wrapWith(new Element('div', {id: 'master'})); After: <div id="master"> <p>Something</p> <p>Something1</p> <p>Something2</p> <p>Something3</p> </div>

  • jQuery: Fade not working

    - by Rosarch
    For some reason, jQuery's fade effect isn't working. Could it be because of the code? This function does everything it is supposed to, aside from the fading. It gets called at the correct time. function moveToTerm(original_course, helper, term) { var cloned_course = original_course.clone(true); original_course.addClass('already-scheduled'); helper.fadeOut(function() { cloned_course.appendTo(term).attr('style', '').fadeIn("slow"); }); } UPDATE: It fails in both FF 3.5.9 and IE 8.

  • Securing database keys for client-side processing

    - by danp
    I have a tree of information which is sent to the client in a JSON object. In that object, I don't want to have raw IDs which are coming from the database. I thought of making a hash of the id and a field in the object (title, for example) or a salt, but I'm worried that this might have a serious effect on processing overhead. SELECT * FROM `things` where md5(concat(id,'some salt')) = md5('1some salt'); Is there a standard practice for obscuring IDs in this kind of situation?

  • Django admin panel doesn't work after modify default user model.

    - by damienix
    I was trying to extend user profile. I founded a few solutions, but the most recommended was to create new user class containing foreign key to original django.contrib.auth.models.User class. I did it with this so i have in models.py: class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) website_url = models.URLField(verify_exists=False) and in my admin.py from django.contrib import admin from someapp.models import * from django.contrib.auth.admin import UserAdmin # Define an inline admin descriptor for UserProfile model class UserProfileInline(admin.TabularInline): model = UserProfile fk_name = 'user' max_num = 1 # Define a new UserAdmin class class MyUserAdmin(UserAdmin): inlines = [UserProfileInline, ] # Re-register UserAdmin admin.site.unregister(User) admin.site.register(User, MyUserAdmin) And now when I'm trying to create/edit user in admin panel i have an error: "Unknown column 'content_userprofile.id' in 'field list'" where content is my appname. I was trying to add line AUTH_PROFILE_MODULE = 'content.UserProfile' to my settings.py but with no effect. How to tell panel admin to know how to correctly display fields in user form?
