  • Custom login in Django

    - by alpgs
    Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

  • Stuck with jQuery thumbnail gallery behavior

    - by Vitor
    Hi everyone, I'm trying to create a simple thumbnail viewer with jQuery. Here goes the code: $(function(){ $("ul.thumbnails li").click(function(e){ var imgAlt = $(this).find('img').attr("alt"); //Get Alt Tag of Image var imgTitle = $(this).find('a').attr("href"); //Get Main Image URL $("img.featured").attr({ src: imgTitle , alt: imgAlt}); //Switch the main image (URL + alt tag) }); <div class="image-gallery"> <img class="featured" src="big.jpg"> <ul class="thumbnails"> <li id="thumb01"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb02"> <a href="big.jpg"><img src="small.jpg"></a> </li> <li id="thumb03"> <a href="big.jpg"><img src="small.jpg"></a> </li> </ul> .thumbnails li { margin: 0; padding: 5px 5px 0 5px; list-style: none; float: left; overflow: hidden; } thumbnails li img { width: 50px; height: 50px; margin: 0; padding: 0; float: left; } If i click the thumbnail, the browser goes straight to the full image instead of just changing the img src with jQuery. But I if i click somewhere inside the <li> it works. I know this must be simple, but I don't know where I'm going wrong. I've tried studying other galleries, like http://www.sohtanaka.com/web-design/examples/image-rotator/ , but couldn't find what I'm missing. I could really use some help from you guys :)

  • Combining consecutive dates into ranges

    - by Ragha J
    I have a List of objects public class sample { public DateTime Date; public string content; } I want to be able to create a list of new objects public class sampleWithIntervals { public DateTime startDate; public DateTime endDate; public string content; } The sample objects should be grouped into intervals based on the content. The intervals can include only those dates that are included in the original sample list. I dont know how to do this in Linq. Sample data: {"10/1/2013", "x"} {"10/2/2013", "x"} {"10/2/2013", "y"} {"10/3/2013", "x"} {"10/3/2013", "y"} {"10/10/2013", "x"} {"10/11/2013", "x"} {"10/15/2013", "y"} {"10/16/2013", "y"} {"10/20/2013", "y"} This should give me {"10/1/2013","10/3/2013", "x"} {"10/2/2013","10/3/2013", "y"} {"10/10/2013","10/11/2013", "x"} {"10/15/2013","10/16/2013", "y"} {"10/20/2013","10/20/2013", "y"}

  • Eclipse RCP : make a standalone plugin extending an existing standalone one

    - by akira2x3x
    I have extended via extension point (add menus and functionnalities) an already existing plugin which has it's own product definition file and it's own class Application implements IApplication. I want to create a Product Configuration(customize splash screen,etc...). Does my plugin need an Application class? I want my plugin to be independant, Standalone with a launcher. Not a fragment. Do I have to inherit already existing plugin Application? Thanks for the tips and tricks.

  • jQuery fadeIn() not working in IE

    - by Rob Bennet
    [js] $(document).ready(function() { //Default Action $(".tab_content").hide(); //Hide all content $("ul.tabs li:first").addClass("active").show(); //Activate first tab $(".tab_content:first").show(); //Show first tab content //On Click Event $("ul.tabs li").click(function() { $("ul.tabs li").removeClass("active"); //Remove any "active" class $(this).addClass("active"); //Add "active" class to selected tab $(".tab_content").hide(); //Hide all tab content var activeTab = $(this).find("a").attr("href"); //Find the rel attribute value to identify the active tab + content $(activeTab).fadeIn("slow"); //Fade in the active content return false; }); }); [/js] Works in everything but IE?

  • Why are these styles not visible in IE6

    - by Laramie
    Given the following markup <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML Strict//EN"><META http-equiv="Content-Type" content="text/html; charset=utf-8"> <HTML xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> div.apartBox { padding:12px; background: #FFFFFF; border: solid 1px #6182A3; } .browser { background: #fff; border: solid 1px #0055E3; border-top: solid 12px #0055E3; border-bottom: solid 4px #7A99C5; padding:10px 10px 8px 14px; color: #333; font: 0.8em/1 arial; margin: 8px 20px; } .callout { background: #EEF2F0; border: solid 1px #9CC7C0; padding:8px; } </style> </head> <BODY> <div class="apartBox" id="subPopout" style="Z-INDEX: 2; WIDTH: 400px; POSITION: relative"> <div id="upSubPop"> <div class="callout" id="subDetails"> <div class="browser"> <span id="txtExample">Me afecta que digan que soy incapaz.</span> </div> </div> </div> </div> </BODY></HTML> The styles from the css .browser and .callout are not visible in IE6 unless I manually remove the position:relative style from subPopout. This div is generated automatically from a modal popup so I unfortunately can't touch this style. It displays fine in FF. If I select the .browser div with my mouse, it displays when I unselect it!

  • How to access private static target field in aspect in AspectJ?

    - by LihO
    I have a simple class Main with private static int x and an aspect that should output the old value of x before it is reassigned: public class Main { private static int x; public static void main(String[] args) { foo(7); } public static void foo(int y) { x = y; } } and MonitorX.aj: public aspect MonitorX { before() : set(static int Main.x){ System.out.println(Main.x); } } which doesn't work since I can't access private x using Main.x. I've also tried: before(int t) : set(static int Main.x) && target(t){ System.out.println(t); } which doesn't work either (nothing is outputted, if I try to output string, it seems that the aspect isn't invoked at all). However printing out the new value that is being assigned works: before(int newVal) : set(static int Main.x) && args(newVal){ System.out.println(newVal); } What am I missing?

  • How come this image won't resize to fit the sprite?

  • Code to make div appear after a certain amount of time.

    - by user307783
    Hi, I'm looking for code that makes a div appear after a certain amount of time on a site. Here's the sort of thing I'm talking about: <div class="container"> <div class="secretpopout"> This is the div I want to pop out after a couple of minutes. </div> </div> I'm relatively new to javascript and jQuery, but I'm assuming I will need to use the setTimeout or something similar. I've tried finding the answer online, but if someone could explain it in a way a designer (as opposed to a programmer) would get it, that would be great - ANY LIGHT shed on this would be greatly appreciated. Thank you.

  • SelfReferenceProperty vs. ListProperty Google App Engine

    - by John
    Hi All, I am experimenting with the Google App Engine and have a question. For the sake of simplicity, let's say my app is modeling a computer network (a fairly large corporate network with 10,000 nodes). I am trying to model my Node class as follows: class Node(db.Model): name = db.StringProperty() neighbors = db.SelfReferenceProperty() Let's suppose, for a minute, that I cannot use a ListProperty(). Based on my experiments to date, I can assign only a single entity to 'neighbors' - and I cannot use the "virtual" collection (node_set) to access the list of Node neighbors. So... my questions are: Does SelfReferenceProperty limit you to a single entity that you can reference? If I instead use a ListProperty, I believe I am limited to 5,000 keys, which I need to exceed. Thoughts? Thanks, John

  • how to modify this jquery syntax

    - by Gandalf StormCrow
    Hi all, this example below works when hover event is trigered and when its not, its working for elements already in DOM, but when element created dynamically it doesn't work, I realize I need to use jQuery live() or delegate() for this, the thing is I tried to modify it and its not producing the results as expected, here is the working code : $(".sidebar li").hover( function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Here is the bit when I wanted to add live but it's not producing correct results : $(".sidebar li").live('hover', function(){ $(this).css("background-color", "#F9F4D0"); $(this).append($('<button class="promoter" type="button" title="Active promotion"></button>')); }, function(){ $(this).css("background-color", "#F9FAFA"); $(this).children("button").remove(); } ); Where did I made mistake, thank you

  • How can you query for an object using one of its properties' id

    - by James Smith
    I have two entities, say, House and People, where multiple people can live in one house. It's a unidirectional link where each Person has a field for which House they belong to, so the Person table has a column named house_id. I need to be able to return all the Person objects who belong to a certain House, but I only have the id of the house. This can be done like this: House house = houseDAO.findById(houseId); List people = session.createCriteria(Person.class).add(Restrictions.eq("house", house)).list(); But since I don't need the house, that's adding an unnecessary query. I've tried to do: session.createCriteria(Person.class).add(Restrictions.eq("house_id", houseId)).list(); But that doesn't work because house_id is not a property, it's a database column. I could just add an sql restriction, but is there a hibernate way of doing this?

  • Minify an Entire Directory While Keeping Element/Style/Script Relationships?

    Do any solutions currnetly exist that can minify an entire project directory? More importantly, do any solutions exist that can shorten classnames, id's, and keep them consistent throughout all documents? Something that can turn this: Index.html --- <div class="fooBar"> <!-- Code --> </div> Styles.css --- .fooBar { // Comments and Messages background-color:#000000; } Index.js --- $(".fooBar").click(function(){ /* More Comments */ alert("fooBar"); }); Into This: Index.html --- <div class="a"></div> Styles.css --- .a{background-color:#000;} Index.js --- $(".a").click(function(){alert("fooBar");});

  • eclipse: how to debug a Java program as a .jar file?

    - by Jason S
    I use ant for creating .jar files in Eclipse. Works great. I have a .jar file I am working on that expects the code to be in a .jar file (it looks for .properties files in the same directory as the .jar file) -- the standard Eclipse "Run" and "Debug" menus execute the main() method of a specified Java class... but they do it from the directory containing the compiled class files, not a jar file. Is there a way to change this behavior so Eclipse runs code from the appropriate .jar file instead? (My workaround right now is to run the .jar file externally, with it suspended waiting for a debugger, per Dave Ray's answer to one of my other questions.)

  • Help filtering childs

    - by lidermin
    Hello, I have this jquery code: $(".button-banc").hover(function() { $(".button-banc img") .animate({ top: "-21px" }, 200).animate({ top: "-17px" }, 200) // first jump .animate({ top: "-19px" }, 100).animate({ top: "-17px" }, 100) // second jump .animate({ top: "-18px" }, 100).animate({ top: "-17px" }, 100); // the last jump }); The effect I want is: when you pass the mouse over an image this image should jump a bit. The problem is that I got "some" images with the class "button-banc" and I want this behaive: When you pass the mouse over, "only the actual image" should jump. The problem is that with the code I posted, every image jumps. How can I achieve this, please help; I want to make a generic way, so that if I add images with the class, they also behaive like that. Thanks.

  • How can I restore my laptop from Windows 7 to its original Windows Vista recovery partition?

    - by Cam Jackson
    I bought my Acer laptop 4 years ago with Vista Home Premium x86. It has a recovery partition that I have used successfully in the past to format everything and reinstall Windows to factory settings. I have since upgraded to Windows 7, but I now need to get back to my original installation. Not sure what it's called, but I can successfully get into this recovery thingy: However, when I click the third option (for me I think it says 'Windows Image Recovery' or something like that) it tells me that it can't find any images to recover from :( I have checked and I don't have a windows.old that I can recover from either. One final note, if I launch diskmgmt.msc, these are the partitions: Why is the first partition shaded? Does that mean anything? Both of the 'unlettered' partitions are 100% empty. Did the Windows 7 upgrade process format my Vista system recovery partition?! And finally: How can I get back to my factory settings? EDIT: I did see this question, but neither of the answers apply to my situation. Edit to address jdh's answer: From what I can tell, I never get the option to boot the Vista recovery partition. After hitting F10, I get this screen, except it's partition 2, and I don't have the IN/MINT bit: I hit Escape, and then I get this screen, except without Ubuntu listed, and without the auto-countdown thing: I hit F8, and then I get this screen: I hit Enter on the first option, I end up at the screen in the first screen shot. As I said, from there I click the third option, and it fails to find the image, which I guess makes sense if it's only looking for a Windows 7 recovery. So I either need to make the Windows 7 tool see the Vista recovery partition, or I need the boot loader (?) to let me select Vista earlier in the process. Any ideas?

  • How do I execute a sequence of servlets?

    - by Legend
    I have some servlets that act as individual URLs for populating a database for some dummy testing. Something of the form: public class Populate_ServletName extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setContentType("text/plain"); //Insert records //Print confirmation } } I have about 6 such servlets which I want to execute in a sequence. I was thinking of using setLocation to set the next page to be redirected but was not sure if this is the right approach because the redirects should happen after the records have been inserted. Specifically, I am looking for something like this: public class Populate_ALL extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setContentType("text/plain"); //Call Populate_1 //Call Populate_2 //Call Populate_3 //... } } Any suggestions?

  • How to do simple math in datagridview

    I am new to C#. I have a datagridview with 9 columns. I am simply trying take the value in column 5 and subtract it from column 6. Then display the result in column 9. It seems simple enough.I know it's done in excel all the time. But I just cannot figure this out. Do I need to create a new class with a method called calculate columns? or does the datagridview class have something already built in that can handle this? Again, I am new to C#. Any help would be appreciated. Thank you, Oceantrain.

  • Dropdown sorting in django-admin

    - by Andrey
    I'd like to know how can I sort values in the Django admin dropdowns. For example, I have a model called Article with a foreign key pointing to the Users model, smth like: class Article(models.Model): title = models.CharField(_('Title'), max_length=200) slug = models.SlugField(_('Slug'), unique_for_date='publish') author = models.ForeignKey(User) body = models.TextField(_('Body')) status = models.IntegerField(_('Status')) categories = models.ManyToManyField(Category, blank=True) publish = models.DateTimeField(_('Publish date')) I edit this model in django admin: class ArticleAdmin(admin.ModelAdmin): list_display = ('title', 'publish', 'status') list_filter = ('publish', 'categories', 'status') search_fields = ('title', 'body') prepopulated_fields = {'slug': ('title',)} admin.site.register(Article, ArticleAdmin) and of course it makes the nice user select dropdown for me, but it's not sorted and it takes a lot of time to find a user by username.
