my android app, source controlled git, 2 branches, dev , master (for release). added ant task auto increment versioncode. need build dev quick verification , build master release properly. if every build increments versioncode, necessary push change git? i'm confused now, because believe versioncode should got version controlled along source code. if so, branch dev , master may different versioncode , can cause further conflict while doing code merging. if let build machine cache versioncode , incremente based on that, looks it's simple solution, versioncode in source never changed. i want know how manage versioncode in common case development , production environment. versioncode updates build script noise in version control. there's no point in versioning them. instead, consider creating tag in version control each build tag name , version code / version name can mapped. way there's less noise in version history , can still know code went build. ...

i´m trying insert values database several tables: insert dbo.table1 (id, idtable2, idcounter) select s.id o.idtable2 o.idcounter dbo.table3 o, dbo.table2 s but above code leads situation duplicate values values table 3, want 1 value table3 per value table 2. (the tables don´t have relationship info) thanks in advance. edit: thanks everyone. managed solve adding reference id table2 , using inner join. you forgot clause joining tables table2 , table3, building cartesian product. there must linking tables; otherwise makes no sense combine them do. my advice: stay away old join syntax list tables comma-separated. use up-to-date join syntax (inner join on etc.) instead. having said this, don't see how select make sense anyhow. id become id of table2 , idtable2 become id of table2, too?

i know can extract sales order data in opencart database, in table shop_order , shop_order_product . is possible differentiate user creates sales order? i don't think there's option identify admin user created order. may need code yourself. below steps may you. add 2 new fields created_user_id , updated_user_id in order table - default value 0. update admin/model/sale/order.php insert values fields $this->user->getid(); ( addorder , editorder functions ). add new field user_id in order_history table - default value 0. update admin/model/sale/order.php insert value field $this->user->getid(); (function: addorderhistory ). you can these directly modifying files or using vqmod. if it's done via vqmod it'll easier make changes during opencart version upgrade. opencart: vqmod tutorial have nice day!!

when updating record existing file if file has changed need remove old file s3 bucket. how in django can detect if file has changed? this have tried (not tested) django have magic build in this? def save(self, *args, **kwargs): existing_file = asset.objects.get(pk=self.pk) if existing_file != self.file: # remove s3 before saving new file == , != compare primary keys of model instances (look @ __eq__() , __ne__() methods implementation ). one way compare fields of model instances call model_to_dict() on both: from django.forms.models import model_to_dict if model_to_dict(existing_file) != model_to_dict(self.file): you can specify fields , exclude arguments control fields dump dictionary, in case, fields compare. hope helps.
