  • jQuery - Dynamically adding validation rule to multiple textboxes

    - by Justin
    Hey, I'm trying to add a validation rule to multiple textboxes dynamically. Here's the js: //validate form. $("#SubmitForm").validate(); $("input[id*=Hours]").rules("add", { number: true, messages: { number: "Please enter a valid Hours" } }); This applies the rule to the very first textbox on the page with "Hours" in the id but then it doesn't apply it to any of the other ones. Anyone know what's wrong here? Thanks, Justin

  • Comments in string and strings in comments

    - by Jay Gridley
    Hi there, I am trying to count characters in comments included in C code using Python and Regex, but no success. I can erase strings first to get rid of comments in strings, but this will erase string in comments too and result will be bad ofc. Is there any chance to ask by using regex to not match strings in comments or vice versa?

  • Having a POST'able API and Django's CSRF Middleware

    - by T. Stone
    I have a Django webapp that has both a front-end, web-accessible component and an API that is accessed by a desktop client. However, now with the new CSRF middleware component, API requests from the desktop client that are POST'ed get a 403. I understand why this is happening, but what is the proper way to fix this without compromising security? Is there someway I can signal in the HTTP header that it's an API request and that Django shouldn't be checking for CSRF or is that a bad strategy?

  • Myfaces extensionfilter overriding renderkit? (Tree2 component)

    - by Mike
    I've pulled in the tree2 component (from Tomahawk 1.1.9). Had used the simpler Tree component on previous projects, and this one just looks a bit nicer. Running on websphere 6.1.x and set the server side flag that's needed (com.ibm.ws.webcontainer.invokefilterscompatibility=true) and set the extensionfilter accordingly. Everything's good, and works as expected. Here's the issue: - on a page being included on this one (just some typical footer type info with NO myfaces widgets), there's some embedded html that's getting flagged with warnings in the systemout console). These look like org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 475. Surroundings: 'span id="tile:footr:viewFragm'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 479. Surroundings: 'a id="tile:footr:viewFragment'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 492. Surroundings: 'a id="tile:footr:viewFragment'. The problem isn't necessarily with the html (which should be cleaned up regardless :-). IF I don't include myfaces, I don't get these warning messages with the default ibm jsf renderer (using jsf 1.1 still). Obviously, IBM's implementation is a bit more lax than myFaces. The page has nothing to do with myfaces at all. The reason for needing the extension filter is that it needs (for the Tree2 anyways, I know it does more for file upload) to intercept requests and then stick some .js includes on the page. Investigated this a bit, and I've included this filter in my web.xml, but it is NO longer fronting the faces servlet. So, the filter is instantiated at startup, but is never executed. Since the filter isn't in place, I've had to hard code in the includes for the 2 .js files into my page Now, the tree2 gets rendered properly, AND I'm not getting the warnings from above, because with the extentionfilter not being called, its using the IBM renderkit ;-) I'm a bit concerned that when the extension filter is in place, everything is being rendered by myFaces, rather than IBM's renderkit (i.e. All I want is myfaces/tomahawk to render the tree2 only, and let the ri do everything else) Can anyone confirm this? When you use myfaces/tomahawk, is it doing all the rendering for the whole application, or just the page any tomahawk widget is on? Thanks for any thoughts on this mike

  • django: CheckboxMultiSelect problem with db queries

    - by xiackok
    firstly sorry for my bad english there is a simple model Person. That contains just languages: LANGUAGE_LIS = ( (1, 'English'), (2, 'Turkish'), (3, 'Spanish') ) class Person(models.Model): languages = models.CharField(max_length=100, choices=LANGUAGE_LIST) #languages is multi value (CheckBoxSelectMultiple) and here person_save_form: class person_save_form(forms.ModelForm): languages = forms.CharField(widget=forms.CheckBoxSelectMultiple(choices=LANGUAGE_LIST)) class Meta: model = Person it is ok. but how can i search persons for languages like "get persons who knows turkish and english" in the database (MySQL) record "languages" column seen like "[u'1', u'2']". but i want search persons like this: persons = Person.objects.filter(languages__in=request.POST.getlist('languages'))

  • Are soft deletes a good idea?

    - by Khou
    Are soft deletes a good idea or a bad idea? Instead of actually deleting a record in your database, you would just flag it as "IsDeleted" = true, and upon recovery of the record you could just flag it as "False". Is this a good idea?

  • How to Minify .net AXD Resources

    - by Ilya Biryukov
    Hey I am working on a big .NET project. I am currently creating an automated minifier for JS and CSS files using YUI compressor. After doing some research, I found that the heaviest files in the project are actually .NET resources (Like MS ajax file). They are very big and unminified. I am wondering, is there any way to minify them? Thanks

  • How much abstraction is too much?

    - by Daniel Bingham
    In an Object Oriented Program: How much abstraction is too much? How much is just right? I have always been a nuts and bolts kind of guy. I understood the concept behind high levels of encapsulation and abstraction, but always felt instinctively that adding too much would just confuse the program. I always tried to shoot for an amount of abstraction that left no empty classes or layers. And where in doubt, instead of adding a new layer to the hierarchy, I would try and fit something into the existing layers. However, recently I've been encountering more highly abstracted systems. Systems where everything that could require a representation later in the hierarchy gets one up front. This leads to a lot of empty layers, which at first seems like bad design. However, on second thought I've come to realize that leaving those empty layers gives you more places to hook into in the future with out much refactoring. It leaves you greater ability to add new functionality on top of the old with out doing nearly as much work to adjust the old. The two risks of this seem to be that you could get the layers you need wrong. In this case one would wind up still needing to do substantial refactoring to extend the code and would still have a ton of never used layers. But depending on how much time you spend coming up with the initial abstractions, the chance of screwing it up, and the time that could be saved later if you get it right - it may still be worth it to try. The other risk I can think of is the risk of over doing it and never needing all the extra layers. But is that really so bad? Are extra class layers really so expensive that it is much of a loss if they are never used? The biggest expense and loss here would be time that is lost up front coming up with the layers. But much of that time still might be saved later when one can work with the abstracted code rather than more low level code. So when is it too much? At what point do the empty layers and extra "might need" abstractions become overkill? How little is too little? Where's the sweet spot? Are there any dependable rules of thumb you've found in the course of your career that help you judge the amount of abstraction needed?

  • What is the optimal way to run a set of regressions in R.

    - by stevejb
    Assume that I have sources of data X and Y that are indexable, say matrices. And I want to run a set of independent regressions and store the result. My initial approach would be results = matrix(nrow=nrow(X), ncol=(2)) for(i in 1:ncol(X)) { matrix[i,] = coefficients(lm(Y[i,] ~ X[i,]) } But, loops are bad, so I could do it with lapply as out <- lapply(1:nrow(X), function(i) { coefficients(lm(Y[i,] ~ X[i,])) } ) Is there a better way to do this?

  • Fastest gap sequence for shell sort ?

    - by Tony
    According to Marcin Ciura's Optimal (best known) sequence of increments for shell sort algorithm. The best sequence for shellsort is 1, 4, 10, 23, 57, 132, 301, 701... But how can I generate such a sequence ? In Marcin Ciura's paper he said : Both Knuth’s and Hibbard’s sequences are relatively bad, because they are defined by simple linear recurrences but most algorithm books I searched , they all tend to use Knuth’s sequence : k = 3k + 1 ; because it's easy to generate , what's your way of generating shellsort sequence ?

  • jquery horizontal scroll with mousewheel

    - by steve
    I currently have a site that is a sidescroller (http://www.studioimbrue.com) and I'm trying to bind a mousewheel to scroll sideways. Currently I'm using the one found at thehorizontalway.com (called thw.js) but it doesn't seem to work in all browsers (Chrome). I'm trying to get this one to work: http://brandonaaron.net/code/mousewheel/docs , to simply scroll the whole window, nothing else. There is very limited documentation so I can't figure it out. Any help is appreciated.

  • Cut and Paste Code Reuse - JavaScript and C#

    - by tyndall
    What is the best tool(s) for tracking down "cut and paste reuse" of code in JavaScript and C#? I've inherited a really big project and the amount of code that is repeated throughout the app is 'epic'. I need some help getting handle on all the stuff that can be refactored to base classes, reusable js libs, etc... If it can plug into Visual Studio 2010, that would be an added bonus.

  • Can rpmbuild ingore files in buildroot?

    - by Noah Campbell
    I have a target directory that is checked into svn. I use the target as the --buildroot when I run rpmbuild. This causes rpmbuild to loose it mind because of the .svn directories in each directory. Is there a way to tell rpmbuild to relax? I looked at svn export target target-build, but it only knows about files tracked by rpm. Perhaps not a bad way to do it, but I'm not quite sure that is the best way.

  • Django: How to get current user in admin forms

    - by lazerscience
    In Django's ModelAdmin I need to display forms customized according to the permissions an user has. Is there a way of getting the current user object into the form class, so that i can customize the form in its __init__ method? I think saving the current request in a thread local would be a possibility but this would be my last resort think I'm thinking it is a bad design approach....

  • Zoom in UIImageView without scrollView nor WebView

    - by camilo
    Hi, Is there any code example teaching how to zoom in and out in a UIImageView by user taps? I know it is possible to do it with UIScrollView and with UIWebView, but these solutions both need a lot of changes in the code, and I'm working on schedule (bad teachers). I wanted basically an example on how to manipulate directly the UIImageView. Thanks a lot!
