Say that I inherited the model's legacy as defined below.
ArticleBase (Models.Model): title = models.CharField () Author = models.CharField () Category Review: Rating = models.IntegerField () Class News (ArticleBase) : Source = models.CharField () If I need a list of all the articles, even if (in this case the order has been ordered in both the review and the news), I ArticleBase Once I can run a query, I have a paragraph base record to determine whether it asks both questions of a model. Received related to a review or news records, foreign keys which have recorded?
I am assuming that all paragraph examples are examples of article subsection subclasses.
A solution is to collect subclass names in ArticleBase and some methods that return the subclass or subclass objects based on that information. Since multi-table succession defines an asset at the original frequency to reach a child's example, it is all very straight forward. Paragraph Base (models.Model) from the category of Django.db import models:
= Models.CharField () Author = models.CharField () # Store the name of the actual class. Class_name = models.CharField () # Define that the class_name is set to ensure it is saved. Def Save (self, * args, ** quorz): self.class_name = self .__ class______________ super (paragraph, self). Savings (* Args, ** kwargs) # Multi-table succession defines a specialty to bring the child to the # short case Sub-class named Def get_child (self): Return getattr (self, self. Class_name.lower ()) #If actually you really need the class. Def get_child_class (self): back self .get_child () .__ class__ # Check the type against a subclass name or subclass # For example, 'if the article Child_IS (News): '# or' if article. Child_is ("news"): '. Def child_is (self, cls): ifinstance (cls, bassstring): return cls.lower () == self.class_name.lower () Other: return self.get_child_class () == CLS class review (ArticleBase): Rating = Models.IntegerField () Class News: Article source = models.CharField () </code> </pre> <p> This is not the only way to go about this. This, however, is a very simple and straight forward solution. Excellent stuff content type applications and generic modules that take advantage of it, they offer a variety of ways to do this, well, normally. </p> <p> This article can be useful for the following in Base: </p> <pre> <code> def __unicode __ (self) returns self.get_child () .__ Unicode __ () </code> </pre> <p> In that case, be aware that the failure to define <code> __unicode __ </code> in sub-codes, or on an event of ArticleBase (one that has not been subclassed) <code > __Unicode __ </code> calling will lead to an infinite recursion, thus following advice, discretion check (for example, directly in this way the RTIs An immediate stop) </p> <p> <strong> Disclaimer: </strong> </p> <p> This code is unwanted, I 'm convinced that there is a typo or two in it, but the original concept should be sound. There should be some flawed check in the production level code so that usage errors can be stopped. </p> </div> </html> <br />

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
