  • Instantiating and referencing models in MVC

    - by fig-gnuton
    In MVC, should each model be a globally accessible singleton accessible to any view/controller? Or should the models be singletons that are dependency injected into any component that requires them? Or should a new model instance be created for each component that needs one, in which case events would be used to propagate changes across model instances of the same class?

  • Django m2m adding field in the secondary table

    - by dana
    I have a model in wich i'm using m2m Django ORM feature, in order to create an aditional table to hold my 'classrom members'. My problem is: the membership to a classroom must be accepted by the invited one, so i need a boolean field :1=accepted, 0=refused/unseen yet. How can i include this boolean variable in the aditionally generated classroom_membership (and NOT in the primary created Classroom table)? class Classroom(models.Model): user = models.ForeignKey(User, related_name = 'classroom_creator') classname = models.CharField(max_length=140, unique = True) date = models.DateTimeField(auto_now=True) open_class = models.BooleanField(default=True) #domain = models.EnumField() members = models.ManyToManyField(User,related_name="list of invited members") Thanks in advance!!

  • Validating a wrong date entry in rich faces

    - by Hiral Lakdavala
    Hi, (On behalf of a collegue) In one of our functionality we have some date fields for inline edit where we have enabled manual input. If in rich:calendar component, we manually enter improper date or junk data it will not even call the action method. As per our requirement we need to display an error message for date validation for these kind of fields. Is there any way to track that the date entered in the calendar field is improper with this component. Code for the reference: <rich:calendar id="actualOpeningDtCal" rendered="#{!empty storeProgram.id}" value="#{storeProgram.actualOpeningDate}" placeholder="dd-mmm-yyyy" inputSize="20" enableManualInput="true" datePattern="dd-MMM-yyyy" buttonIcon="../content/images/calendar.png" showWeeksBar="false" showFooter="false"> <a4j:support event="oninputblur" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> <a4j:support event="oncollapse" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> </rich:calendar> Regards, Hiral

  • Render Silverlight Animation to video file

    - by VOliveira
    Hi guys I need to be able to render a silverlight storyboard animation to video. The animated content itself could be simple UIElements, Images or even two or more videos playing at the same time. Several ideas came to mind like RenderTargetBitmap on a single frame basis, but: 1) I've never tested this against video embedded content 2) Don't know how to actually compose the video from the generated images. Expression Encoder was also on my mind, but I don't know if it's possible to integrate it in a Silverlight/XBAP app to fulfill what's expected from it. What's your opinion on this?

  • Is there a Utility that will scan selected locations and return all files older than a certain date?

    - by CT
    Can anyone recommend a utility that can scan specified directory locations (network shares specifically) and return all files older than a certain date? I am looking to implement a data retention policy at my workplace. As our amount of data grows it puts a large strain on our backup routines. I would like to move old data to some sort of archival system. Extra points for the ability to move queried old files to another location for archival and the ability to create schedules for when this occurs. Many thanks. EDIT: Windows Shop. Mostly Windows 2003 Servers.

  • Declaration of struct variables in other class when obtained by getters

    - by liaK
    Hi, I am using Qt 4.5 so do C++. I have a class like this class CClass1 { private: struct stModelDetails { QString name; QString code; ..... // only variables and no functions over here }; QList<stModelDetails> m_ModelDetailsList; public: QList<stModelDetails> getModelDetailsList(); ... }; In this I have functions that will populate the m_ModelDetailsList; I have another class say CClassStructureUsage, where I will call the getModelDetailsList() function. Now my need is that I have to traverse the QList and obtain the name, code from each of the stModelDetails. Now the problem is even the CClass1's header file is included it is not able to identify the type of stModelDetails in CClassStructureUsage. When I get the structure list by QList<stModelDetails> ModelList = obj->getModelInformationList(); it says stModelDetails : undeclared identifier. How I can able to fetch the values from the structure? Am I doing anything wrong over here?

  • Entitiy Framework: "Update Database from Model" instead of "Generate Database from Model"

    - by David
    Hey everyone, I have created a Entity Framework 4 model with Visual Studio 2010 and generated a database from it. Now I found myself adding new properties (with default values), changing documentation of columns, changing names of columns, changing types of columns several times. All tasks that do not require much "extra work" in order not to be possible to be achieved automatically (in my humble opinion). Everytime I did "Generate Database from Model" and lost of course the table data. Is there a way just to update the database's architecture so to say - leaving the table data untouched? Maybe with some user interaction especially when changing types etc.? Or would this functionality be simply too difficult to be realized to work in a reliable way? Thanks in advance! Cheers, David

  • How to escape <, >, and & characters to html entities in Oracle PL/SQL

    - by SWilk
    Hi, I need to send HTML emails directly from oracle PL/SQL package. This works almost fine. I have problem with the fact that some of the data fetched from a table contain things like <S>, <L>, and similar fragments, which sometimes ar treated as HTML tags, and even if not, they are always ignored and never displayed. So, I need to escape this column before inserting into email body. Is there a function to escape html special chars into entities automaticly? Or do I need to replace('<','&lt;',string) manually all the special characters? I found a function to escape URLs but not one for HTML :( Best regards, SWilk
