there file main.py in folder a. folder b subfolder of folder a. there files subfolder.py , data.txt inside folder b. subfolder.py has function reads data.txt . reading happens when run file subfolder.py now in main.py import subfolder.py , call function reads data.txt says "no such file or directory data.txt " don't understand do. can help? could please show function in subfolder.py . the program may unsure of data.txt file is. run in first file: import os print os.path.dirname(os.path.realpath(__file__)) then add on string needed if python behaves in way expect behave, may need run import os filepath = os.path.dirname(os.path.realpath(__file__))+"\\"+"subfolder"+"\\"+"data.txt" and use filepath in function in subfolder.py open data.txt. does help?

i have following models class parent < activerecord::base has_many :children end class child < activerecord::base belongs_to :parent end what want changing child object parent.children.find_or_initialize_by() , modify child object, save parent.save . children doesn't saved. here's code. # prepare parent child p = parent.new({:name=>'parent'}) p.children << child.new({:name => 'child'}) p.save # modify , save child p = parent.first c = p.children.find_or_initialize_by({:name=>'child'}) #=> returns child created above c.name = 'new child' p.save #=> children aren't saved i know because find_by method returns new object rather 1 loaded. seems more natural me if code above works because method invoked through activerecord::associations::collectionproxy . missing work? or there reasons find_by on activerecord::associations::collectionproxy have work does? (i know can save modified child c.save , wa...

i searching solution quite time without luck , hope can expert here. for example, have product class: public class productmodel : observableobject { private int id; public int id { { return id; } set { id = value; onpropertychanged("id"); } } private string name; public string name { { return name; } set { name = value; onpropertychanged("name"); } } private decimal unitprice; public decimal unitprice { { return unitprice; } set { unitprice = value; onpropertychanged("unitprice"); } } } and have class called order: public class order : observableobject { sportsentities db; private int id; public int id { { return id; } set { id = value; onpropertychanged("id"); } } private int productid; public int productid { { return productid; } set { productid = valu...

this question has answer here: manytomanyfield relationships between multiple models 1 answer i have 2 models in django app, both models contain multiple instances of other class. eg) topic can contain many books, , book may belong many topics. so, both must have manytomanyfield of other. code: class topic(models.model): books = models.manytomanyfield(book) class book(models.model): topics = models.manytomanyfield(topic) now problem is, error 'book' not defined. how rid of this? pass name of model string manytomanyfield instead of model itself, see here ( foreignkey behaves same way). code: class topic(models.model): books = models.manytomanyfield('book') class book(models.model): topics = models.manytomanyfield('topic') edit: i blindly answered without noticing same thing daniel. need have relationshi...

experimenting ildasm dive cil code became obvious cil working stack-based support expressions like il_0001: ldc.i4.s 13 ; 1f 0d il_0003: stloc.0 ; 0a il_0004: ldc.i4.s 31 ; 1f 1f il_0006: stloc.1 ; 0b il_0007: ldloc.0 ; 06 il_0008: ldloc.1 ; 07 il_0009: add ; 58 doing same float32 instead of int32 using ldc.r4 <num> there no difference in calling add making me wonder whether there different stacks different types or if there 1 stack holds metadata type specific element has on stack. there information specific implementation in ecma-335 or somewhere else? this addressed in partition i, part 12 (from e.g. pdf ), discusses virtual execution system (ves): as described below, cil instructions not specify operand types. instead, cli keeps track of operand types based on data flow , aided stack consistency requirement described below. example, single add instruction add 2 integers or ...

assume have 2 modules in 2 separate files: the first everyone, call myapp: var myapp = angular.module('myapp', ['dependency.one', 'dependency.one']); in file: admin.js have module manages administrative functions. var myadmin = angular.module('myadmin', ['dependency.three', 'dependency.four']); only logged in admin users served admin.js. is possible inject myadmin module myapp module within admin.js file? alternately, there way include myadmin stuff, if admin.js file linked in page header, or alternative solution not seeing? $inject not appear work in context. no, not in current (1.x) version of angularjs. when application starts needs provided full set of modules used within application. so, have re-bootstrap whole application take additional modules account.

i want query 2 tables resulting query has more rows should be. my statement is: select * deal d, item d.dealstate = 'accepted' , ((d.owner = 'username1') or (d.itemid = i.itemid , i.owner = 'username1')) , d.deadline < now() with statement want user's active deals. deal table has owner (the requester), dealid, itemid, creationdate, dealstate, deadline, explanation , item table has owner (the owner of item), itemid, itemname, description . the problem want query 1 result. because 'username1' has 1 deal. query 10 rows, each of items matched deal. thought using "join" if user not owner of item, item table won't used. then, should do? i hope i'm clear enough. your query doesn't join correctly 2 tables because d.itemid = i.itemid isn't true in wrote. try select * deal d, item d.dealstate = 'accepted' , d.itemid = i.itemid , ((d.owner = 'username1') or ( i.owne...
