• Joomla! 2.5 use login data from another database

  - by user1756746

  I have a hard question. I'd like the joomla login does not use its own database for users/password but I want to use my database users with my table fields, my passwords etc.. I don't know from where start, I thought I could edit database request for login to my db or create a little script to automatically add the users on joomla database. I tried to see components/com_users/views/login/tmpl/default_login.php but it seems that there is nothing. Can someone help me figure out what to change? Maybe the simple thing is import my database users into database user joomla, is there any plugin or something else that you know? p.s. I use Clarion theme build on Gantry framework, Joomla! 2.5.6 Stable, PHP 5.2.17

• Reusability, testability, code complexity reduction and showing-off-ability programming importance

  - by Andrew Florko

  There are lots of programming and architecture patterns. Patterns allow to make code cleaner, reusable, more testable & at last (but not at least) to feel the follower a real cool developer. How do you rank these considerations for you? What does affect you most when you decide to apply pattern? I wonder how many times code reusability (especially for MVP, MVC patterns) was important? For example DAL library often shared between projects (it's reusable) but how often controllers/views (abstracted via interfaces) are reused?

• Change the contents of a UITableView via a swipe?

  - by Mark

  Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark

• How can I use different metadata for a Dynamic Data form view and the list view?

  - by ProfK

  We often need a summarised list view with more detailed form view. So far, the only two way I can think of doing this are using a 'custom' list or form view than uses a sumplimentary 'remove' or 'add' list of fields anb generalise this over all entity sets, or create a custom metadata provider that infers somehow which columns to supply. Are there any other ways of distinguishing these two views? PS, I wrote a fun little general details page, that handles insert, edit, and view, all on one page template. Maybe I could somehow use that? It's here.

• UITable row to add an item

  - by Moshe

  I want to make a TableView of phrases which the user can edit. The "Phrase editor" is being displayed modally. My top left is for the Done button right now. I'm considering making a button at the end of the table for "new phrase". How would I implement that? Is it a good idea to follow the "contacts" application and make a + button in the top right, or Should I make the "Add Items" button at the end of the list? What are HIG implications of either one? BONUS: Where can I find some tutorials on Navigation Controllers and Table Views? Thanks a ton.

• Region or ItemsSource for large data set in ListBox

  - by Ryan

  I'm having trouble figuring out what the best solution is given the following situation. I'm using Prism 4.1, MEF, and .Net 4.0. I have an object Project that could have a large number (~1000) of Line objects. I'm deciding whether it is better to expose an ObservableCollection<LineViewModel> from my ProjectViewModel and manually create the Line viewmodels there OR set the ListBox as it's own region and activate views that way. I'd still want my LineViewModel to have Prism's shared services (IEventAggregator, etc.) injected, but I don't know how to do that when I manually create the LineViewModel. Any suggestions or thoughts?

• How to control a webView

  - by klaus-vlad

  Hi, In one of my xml layouts I use an webview (besides other TextViews) for which I call loadUrl("myURL") to display the content from a url. The desired effect is to have displayed in a screen all the other textViews , and below them the content of web page. However when the webview loads the URL , it starts a new activity and displays the content in that activity, which is not what I need. Any ideas on how I could force the described behavior ? Later edit: I have succeed to have layout with several views mixed, one of them being the webview .Also I have succeed to obtain the described above behavior. But only after I setted a WebView client with setWebViewClient(WebViewClient); . Now I'd like to know why does it work like this only after a webViewClient is set ?

• Django: Why Doesn't the Current URL Match any Patterns in urls.py

  - by austin_sherron

  I've found a few questions here related to my issue, but I haven't found anything that has helped me resolve my issue. I'm using Python 2.7.5 and Django 1.8.dev20140627143448. I have a view that's interacting with my database to delete objects, and it takes two arguments in addition to a request: def delete_data_item(request, dataclass_id, dataitem_id): form = AddDataItemForm(request.POST) data_set = get_object_or_404(DataClass, pk=dataclass_id) context = {'data_set': data_set, 'form': form} data_item = get_object_or_404(DataItem, pk=dataitem_id) data_item.delete() data_set.save() return HttpResponseRedirect(reverse('detail', args=(dataclass_id,))) The URL in myapp.urls.py looks something like this: url(r'^(?P<dataclass_id>[0-9]+)/(?P<dataitem_id>[0-9]+)/delete_data_item/$', views.delete_data_item, name='delete_data_item') and the portion of my template relevant to the view is: <a href="{% url 'delete_data_item' data_set.id data_item.id %}">DELETE</a> Whenever I click on the DELETE link, django tells me that the request URL: http://127.0.0.1:8000/myapp/5/%7B%%20url%20'delete_data_item'%20data_set.id%20data_item.id%20%%7D doesn't match any of my URL patterns. What am I missing? The URL on which the DELETE links exist is myapp/(<dataclass_id>[0-9]+)/

• Is there something similar to 'rake routes' in django?

  - by The MYYN

  In rails, on can show the active routes with rake (http://guides.rubyonrails.org/routing.html): $ rake routes users GET /users {:controller=>"users", :action=>"index"} formatted_users GET /users.:format {:controller=>"users", :action=>"index"} POST /users {:controller=>"users", :action=>"create"} POST /users.:format {:controller=>"users", :action=>"create"} Is there a similar tool/command for django showing the e.g. the URL pattern, the name of the pattern (if any) and the associated function in the views?

• UIWebView appears null when calling fro a method

  - by Alexidze

  I have a major problem when trying to access a UIWebView that was created during ViewDidLoad, the UIWebView appears null here is how i declare the property @property (nonatomic, retain) UIWebView *detailsView; the implementation @implementation iPadMainViewController @synthesize detailsView; - (void)viewDidLoad { [super viewDidLoad]; detailsView = [[UIWebView alloc] initWithFrame:CGRectMake(500, 0, 512, 768)]; [self.view addSubView:detailsView]; } When accessing from - (void)loadDetailedContent:(NSString *)s { NSLog(@"%@", detailsView); } I get NULL, is it a normal behavior or am i doing something wrong? here is the touchesBegan that is being called, from the views subclass that is being touched, -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { iPadMainViewController *mycontroller = [[iPadMainViewController alloc] init]; self.delegate = mycontroller; [self.delegate loadDetailedContent:NewsId]; }

• Cell Dequeue problem when table inside another table's cell content view

  - by Shailesh Kanzariya

  I am using two table views (Main Table and Sub Table), one table inside other's cell. I am adding Sub Table in Main Table's cell content view. I am also using different Cell Identifier for both table cells. Now, issue is : When - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath is called, very first time cell of Main Table is generated and when I scroll up/down they all are just dequeued, so it is expected and standard behavior and working fine. But, cell of Sub Table is getting created/allocated every time. It is not dequeued as it should be. I guess, its happening because Sub Table is part of Main Table's Cell Content view. But not sure and don't know how to resolve it. Can somebody help me to find the solution?

• Objective-C - Unloading loaded view when it is swapped

  - by teepusink

  Hi, What is the best way to do view management in a multiview application? Right now I have this ViewSwitcher method/function that comes from a custom delegate I created. The code is a whole bunch of if else like this MyViewController *c = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; c.delegate = self; self.myViewController = c; [self.viewHolder insertSubview:c.view atIndex:0]; [c release]; That works fine, but when I visited the function a second time, is there going to be 2 instances of MyViewController now or just 1? How do I unload MyViewController when I switch to another view? Or is there a better way to manage my views? Thanks, Tee

• Django - Empty session data in ajax requests

  - by ninja123

  Hi guys, I have an ajax view where I want to set a session variable like such: def upload(request, *args, **kwargs): request.session['test'] = 'test' request.session.modified = True print request.session.items() I have another normal view something like this: def advertise(request): print request.session.items() I get these two strings printed to shell: [('test', 'test')] [('_auth_user_backend', 'django.contrib.auth.backends.ModelBackend'), ('_auth_user_id', 26L)] Why is the session data that I set in the ajax view not passing to my regular views? If I set session data in regular view, everything works as fine, but it seems that ajax requests contain empty session data? Anybody dealt with something like this before? Any suggestions are greatly appreciated. Thanks.

• iphone app photo upload to server from app threads

  - by user290380

  I have an app that needs to upload a least 5 photos to a server using API call available with the server. For that I am planning to use threads which will take care of photo upload and the main process can go on with the navigation of views etc. What I cant decide is whether it is OK to spawn five separate threads in iphone or use a single thread that will do the upload. In the later cases obviously it will become quite slow. Basically an HTTP POST request will be made to the server with the NSMutableURLRequest object using NSCOnnection. More threads mean more complexity and sync issues, but I can try to write code as neat as possible if it means better performance than a single thread which is simple but is a real stopper if performance is considered. Anybody with any experience in this kinda app. ??

• Django: automatically import MEDIA_URL in context

  - by pistacchio

  Hi, like exposed here, one can set a MEDIA_URL in settings.py (for example i'm pointing to Amazon S3) and serve the files in the view via {{ MEDIA_URL }}. Since MEDIA_URL is not automatically in the context, one have to manually add it to the context, so, for example, the following works: #views.py from django.shortcuts import render_to_response from django.template import RequestContext def test(request): return render_to_response('test.html', {}, context_instance=RequestContext(request)) This means that in each view.py file i have to add from django.template import RequestContext and in each response i have to explicitly specify context_instance=RequestContext(request). Is there a way to automatically (DRY) add MEDIA_URL to the default context? Thanks in advance.

• best way to build iphone settings screen

  - by Christian Schlensker

  I'm building a settings screen for an iPhone app and it is supposed to resemble a grouped table view. Each "cell" should behave like a button. Most cells just have a image view, label view, and disclosure indicator. One will display a value in addition to a label. All of these buttons will present a new view when tapped. Now, how to implement this? I was considering just laying out a set of buttons with custom background images, or would it be best to just use a table view. If that's the case what should it be implemented. So far I've only used table views to display some kind of dynamic data in which each cell displayed the same basic detail view. I'm most curious to figure out how to setup cellForRowAtIndexPath. Would this contain some sort of switch statement to configure each cell individually, or is there an easier way to handle all this?

• UITableView performance degrading after adding subviews on cell iphone sdk

  - by neha

  Hi all, In my application, I'm adding a label and two buttons on cell of UItableView [I have not created a separate cell class]. I'm adding these to cell and not cell.contentview. After I run my application on IPhone, the tableview cell rendering after I move the cells up-down, is very jerky. Is it because I'm not adding the views on cell.contentView or because I've not created a custom class for cell? Can anybody please help? Thanks in advance.

• Django: How do I go about changing my simple app to use Ajax?

  - by swisstony

  I currently have a web page where the user enters some data and then clicks a submit button. I process the data in views.py and then use the same Django template to return and display the original data and the results. What I would like to do is try to give it a bit more of a modern look and feel. You know the sort of thing, the page doesn't refresh but displays a spinning disk until the results are displayed. I assume this means using Ajax? How difficult is it to modify a simple app like this to use Ajax? What is involved? What are the best tools to use? JQuery?

• hierarchical html listbox with mimicking file explorer level folding

  - by collapsar

  hello everybody, i'm looking for a technique to adapt a html listbox to hierarchical content with an unlimited number of levels ( const 1 would be sufficient ). hierarchy levels should be collapsible as in the usual file explorer views. the html listbox behaviour should be preserved / mimicked as comprehensively as possible. do you have a hint on where to find or how to implement this ? jquery solutions are fine. firefox 3.5+, ie 8+, safari 5 must be supported; opera 11, chrome 9 would be nice. as far as i understand the issue, listbox contents are rendered inside their own browser window sporting none of the standard window adornments. a hint on how to obtain a handle on this window in js would be a sufficient starting point, as well as correcting me in case i misconceived the browser behaviour. thanks in advance for your efforts, best regards, carsten

• Open source alternative to Sharepoint lists

  - by Thomas

  Sharepoint's lists functionality is powerful. Because I don't want all the other functionality of Sharepoint, I have been looking for an alternative (preferrable open source) without much success. Basically I want to have a platform or web application that: allows us to define custom datatypes (for different kinds of customer products) has the possibility to create views or forms to present to the user for reading, creating or updating the information of the items of a given datatype a ui to setup this configuration is not required but would be nice to have In an ideal scenario there is an API to get the data out afterwards for further processing.

• Is GOTO really as evil as we are led to believe?

  - by RoboShop

  I'm a young programmer, so all my working life I've been told GOTO is evil, don't use it, if you do, your first born son will die. Recently, I've realized that GOTO actually still exists in .NET and I was wondering, is GOTO really as bad as they say, or is it just because everyone says you shouldn't use it, so that's why you don't. I know GOTO can be used badly, but are there any legit situations where you may possibly use it. The only thing I can think of is maybe to use GOTO to break out of a bunch of nested loops. I reckon that might be better then having to "break" out of each of them but because GOTO is supposedly always bad, I would never use it and it would probably never pass a peer review. What are your views? Is GOTO always bad? Can it sometimes be good? Has anyone here actually been gutsy enough to use GOTO for a real life system?

• How to use Eclipse's Display View for Debug?

  - by jzd

  At the link below it explains that the "display view allows you to manipulate live code in a scrapbook type fashion (see Figure 8). To manipulate a variable, simply type the name of the variable in the Display view, and you'll be greeted with a familiar content assist." http://www.ibm.com/developerworks/library/os-ecbug/ However, I am having trouble getting it to work. I have the view open but all the buttons are disabled. I have tried putting code in the view, selecting code in the view, selecting code in other views, while running and while not running debug, but the only button that is ever enabled on the view is "clear console". Suggestions on what I am doing wrong?
