Stacked Inline with many rows crashing in Django -

-

when trying navigate 'add presentation' in django admin, have wait ~1 minute response render. problem have ~500 slides in database , admin selecting slides 3 different times fill in menues. doing wrong model definitions, wouldn't expect amount of data bring server knees. visibility why experiencing issue way have defined relationships or using django admin?

class presentationtitle(models.model):     title = models.charfield(max_length=255)     order_number = models.integerfield(default=0)      def __unicode__(self):         return self.title  class presentationuser(models.model):     user = models.onetoonefield(user)     authorized_modules = models.manytomanyfield(presentationtitle)   class presentation(models.model):     title = models.foreignkey(presentationtitle)     user = models.foreignkey(presentationuser)     presentation_date = models.datetimefield()      def __unicode__(self):         return self.title.title  class slide(models.model):     ....      submodule = models.foreignkey(submodule)      presentation = models.manytomanyfield(presentation, through='presentationslide')      ...      class meta:         order_with_respect_to = 'submodule'         ordering = ['order']   class presentationslide(models.model):     presentation = models.foreignkey(presentation)     slide = models.foreignkey(slide)     slide_order = models.integerfield()

additionally, admin contains:

class presentationslideinline(admin.stackedinline):                                                                                                                                                            model = presentationslide   class presentationadmin(admin.modeladmin):                                                                                                                                                                     inlines = [presentationslideinline]     admin.site.register(presentation, presentationadmin)

understandably, removing having presentationadmin admin.site.register makes load responsively.

resolved issue -- there culprit @ play: django-debug-toolbar

after removing setup, admin panel presentation loads.

thanks on interest , support, wary of profiling add-ons when experience performance issues.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
