Django Inheritance Issues -

-

okay, have been reading other django inheritance questions , can't find help. may have understanding issue how inheritance works. here issue. start, have 2 base models i'd of other models inherit from. base model contains useful methods of models. second start of account specific object. 

class basemodel(models.model):  # couple of methods models need have. no fields.   class accountmodel(models.model):     ''' base model items related specific account'''      account = models.foreignkey(account)      def save(self, request, *args, **kwargs):         self.account = request.session['account']         super(accountmodel, self).save(*args, **kwargs)

then have 3 models:

class keyword(accountmodel) :     keyword = models.charfield(max_length=300)     #other fields, none required...  class project(accountmodel) :     project_name = models.charfield(max_length=200,verbose_name="project name")     #other fields..  class keywordtarget(basemodel):     keyword = models.foreignkey(keyword)     url = models.urlfield(null=true,blank=true)     project = models.foreignkey(project)

but when try create new keyword, error:

valueerror: cannot assign "'something'": "keyword.keyword" must "keyword" instance.

when do:

kw = keyword(keyword = "something")

where going wrong?

(also, please don't tell me should using manytomany through unless solves problem @ hand)

it looks both basemodel , account model abstract, should specify in models' meta objects like:

class basemodel(models.model):     ...      class meta:         abstract=true

(see http://docs.djangoproject.com/en/dev/topics/db/models/#abstract-base-classes)

i'm guessing without that, you're ending interference between inheriting models.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
