i have entity-class having property of type int32: on generating ddl using devart oracle number(10) column generated. reading , writing instances works flawlessly. however, on fetching instances of entity-class sending custom query executestorequery on objectcontext property seems returned system.double, such constructing instances fails. can hint devart construct system.int32? thank you. bart the reason fact oracledatareader, used in executestorequery method, has type mapping different 1 used in entity framework provider. recommend use numbermappings , suppose need map number(10) int32: number mappings=((number,10,10,system.int32) . these changes should persisted model connection string (they duplicating default ef mapping rules, necessary oracledatareader executestorequery). please let know if problem persists.

i have 2 models like: class manager(models.model) id = models.autofield(primary_key=true) name = models.charfield(max_length=65535, null=false) class employee(models.model) id = models.autofield(primary_key=true) manager = models.foreignkey(manager) name = models.charfield(max_length=65535, null=false) when fetching employees manager, correct way it: mgr = manager.objects.get(id=1) emps = employees.objects.get(manager=mgr) or mgr = manager.objects.get(id=1) emps = employees.objects.get(manager=mgr.id) when creating both parent , child objects, okay this: emp = manager.objects.create(name='john').employees.create(name='johns slave') neither =) mgr = manager.objects.get(id=1) emps = mgr.employee_set.all() and second one. no you'll need them seperately , so: mgr = manager.objects.create(name='john') emp = employee.objects.create(name='johns slave', manager=mgr)

assuming have class such following: class book < activerecord::base validates :title, :length => {:maximum => 10} end is there way (gem install?) can have activerecord automatically truncate values according maximum length? for instance, when write: b = book.new b.title = "123456789012345" # longer maximum length of title 10 b.save should save , return true? if there not such way, how suggest proceed facing such problem more generally? well, if want value truncated if long, don't need validation, because pass. i'd handle this: class book < activerecord::base before_save :truncate_values def truncate_values self.title = self.title[0..9] if self.title.length > 10 end end

i'm adding gui existing command line app. properties used app held in class(es) , i'm creating dialog binds options objects. however, if want cancel out of dialog have reset values of options objects, i'm running probs. i take internal copy of option objects , use re-populate original object allow cancel/rollback seems cumbersome. i can (somehow) implement undo function on each class - there pattern that? i use gui controls standalone hold values , update options objects when dialog has been confirmed. what's best practise? you should consider creating new class used gui. guis have own needs. make sure take care of multi thread issues if have more 1 thread accessing options object. the design patterns address undo functionality called command , memento. think memento fit better on case. take on question on so: design pattern undo engine . following links of interest (and many more): http://www.coderanch.com/t/100676/patterns/memento-vs-com...

i'm attempting create table incremental id. isn't simple id auto_increment. in fact, exact id i'm trying work is: test.script.1/person.n (where n incrementing number) specifically, have table structured as: id | fname | lname | gender | age | each person add in, wish have , incremental id. person 1, test.script.1/person.1 , test.script.1/person.2 second entry , on , forth. is possible this? have searched while in google, not think searching right thing. apologies if there isn't information, , simple question, don't know for. please advise. thanks guys! you can use autoincrementing field trigger populate actual field wish use reference. something this: create trigger set_my_uuid after insert on mytable each row begin set new.uuid_ref_col = concat('test.script.1/person.', new.my_auto_increment_col) end ; where my_auto_increment_col standard autoincrement column in table.

is there way in schema indicate requirement of attributes determined open or closed nature of element. example have element if open has no requirement attribute 'test', if closed required. <element name="employee" > blah! </element> ok <element name="employee" /> fail - attribute 'test' required. i guess using "open" mean element has text node child, , "closed" mean hasn't. you're saying element should either have text node child or attribute not both (?) , not neither. that's classified co-occurrence constraint, , can't done in xsd 1.0. can done assertions in xsd 1.1 <xs:element name="employee" type="..."> <xs:assert test="string(.) or @name"/> </xs:element> xsd 1.1 support available in xerces , saxon.

i'm creating undo-redo mechanism. achieve this, i'm using serialization. recording current state writing bytearrayoutputstream , using objectoutputstream , putting byte[] arraylist. but problem that, of classes holding reference/pointer bufferedimage . don't want serialize because of size (and doesn't implement serializable ). reason why don't want write never change. but different image each instance of class , static keyword isn't solution. my attempt solve: public transient bufferedimage img; this causes objectoutputstream not serialize bufferedimage, won't store reference well. after deserializing, null . so, in short, want keep reference object, not object itself. means that, after deserialazing able use bufferedimage (because of isn't removed garbage collector). many thanks. ok, simple enough, keep map<string, bufferedimage> of images somewhere in application, let each of classes serialize key image. , in readres...

the drag/drop column reordering great feature, how prevent users moving particular (non-data) columns? for example, using checkbox selectors mutli-select grid, column should locked left, while other columns can freely reordered. i looked @ sortable demos on jquery ui , modified setupcolumnreorder function in slick.grid.js exclude items. excluding checkbox column able prevent getting reordered, dragging other columns before it. function setupcolumnreorder() { var checkboxcolumn = $headers.children([0]).attr('id'); $headers.sortable({ items: "div:not('.slick-resizable-handle','#"+checkboxcolumn+"')", ... since checkbox column first, grab id so. bit of hack, worked.

i added .h/.cpp files c functions xcode project. how call c function in objective-c function? when included c file (#import "example.h") in app delegate header file exploded errors (could treated cpp file objective-c) though compiles fine without being included/imported. thanks edit: renaming files m mm fixed issue. getting linker error when building (ld: duplicate symbol)... better research first. again all. if want use c++ objective-c module, change file extension .m .mm .

[note: rereading before submitting, realized q has become bit of epic. thank indulging long explanation of reasoning behind pursuit. feel that, in position undertaking similar project, more on board if knew motivation behind question.] i have been getting structure synth mikael hvidtfeldt christensen lately. tool generating 3d geometry (mostly) context free grammar called eisenscript. structure synth inspired context free art. context free grammars can create stunning results surprisingly simple rulesets. my current structure synth workflow involves exporting obj file structure synth, importing blender, setting lights, materials, etcetera, rendering luxrender. unfortunately, importing these obj files brings blender grinding halt there can thousands of objects complex geometry. 'fairly' because structure synth generates basic shapes, sphere represented triangles still has many faces. thus, generating structures directly in blender preferable current process (blender...
