  • How do I create a Django ModelForm, so that it's fields are sometimes required, sometimes not?

    - by Graf
    Ok, here is the question. Imagine I have a ModelForm which have only two fields. like this one: class ColorForm(forms.Form): color_by_name = forms.CharField() color = forms.IntegerField(widget = forms.Select(choices=COLOR_CHOICES)) So a user can either input a color name, a choose it from a list. Color is required, but that doesn't mean, that user should enter it manually. There do I put validation, so that my code checks if user selected color in dropdownlist and if not then he should write it manually?

  • How can i resolve the N+1 Selects problem ?

    - by Maxime ARNSTAMM
    Hello everyone, I have trouble understanding how to avoid the n+1 select in jpa or hibernate. From what i read, there's the 'left join fetch', but i'm not sure if it still works with more than one list (oneToMany).. Could someone explain it to me, or give me a link with a clear complete explanation please ? I'm sorry if this is a noob question, but i can't find a real clear article or doc on this issue. Thanks

  • Character sets offered in the Eclipse properties

    - by bmargulies
    I've just been handed a pile of Java source that, I suspect, is in ISO-8859-8. Eclipse's menu of charsets, here on my Mac, does not include that. Or any of a wide variety of other encodings supported by the JDK. Is there a recipe for expanding the list of encodings that show up in the menu?

  • How to store a scaleable sized extensible event log?

    - by firoso
    Hello everyone! I've been contemplating writing a simple "event log" that takes a paramater list and stores event messages in a log file, trouble is, I forsee this file growing to be rather large (assume 1M entries or more) the question is, how can I implement this system without pulling teeth, I know that SQL would be a possible way to go. XML would be ideal but not really practical for scaleability if i'm not going nuts. Example Log Entry -----Time Date-------- ---------Sender----------------------- ---------Tags---------- --Message---------- 12/24/2008 24:00:00 $DOMAIN\SYSTEM\Application$ :Trivial: :Notification: It's Christmas in 1s

  • Formatting numbers with significant figures in C#

    - by Chris Farmer
    I have some decimal data that I am pushing into a SharePoint list where it is to be viewed. I'd like to restrict the number of significant figures displayed in the result data based on my knowledge of the specific calculation. Sometimes it'll be 3, so 12345 will become 12300 and 0.012345 will become 0.0123. Occasionally it will be 4 or 5. Is there any convenient way to handle this?

  • A standard event messaging system with AJAX?

    - by Gutzofter
    Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?
