i used retrieve nsimage in subclass of nstextfield obj-c this: nsdictionary *attributedval = [[self attributedstringvalue] attributesatindex:i effectiverange:&effectiverange]; if ([[attributedval allkeys] containsobject:nsattachmentattributename]) { nstextattachment *attachment = [attributedval valueforkey:nsattachmentattributename]; nscell *attachmentcell = (nscell *)[attachment attachmentcell]; ... [[attachmentcell image] name] ... } when try same in swift can't seem able cast attachmentcell compiler error: let attributedval = attributedstringvalue.attributesatindex(i, effectiverange: effectiverange) if let attachment = attributedval[nsattachmentattributename] as? nstextattachment { let attachmentcell = attachment.attachmentcell nscell // not work ... } thanks nate cook. following works: let attributedval = attributedstringvalue.attributesatindex(i, effectiverange: effectiverange) if let attachment = attributedval[nsa...

when sqlalchemy returns: {u'age': datetime.timedelta(12045),} how 12045? i've tried str() , strftime() , , bunch of others, nothing works. from docs , use .total_seconds() length of timedelta. note timedelta you've provided showing days value, timedelta includes seconds , microseconds well. if want days, use .days . age = datetime.timedelta(12045) print(age.total_seconds()) # 1040688000.0 print(age.days) # 12045, not full value represented delta

say have large parent string containing many characters. how can insert string between match of characters (and additionally, erase characters between matching characters)? for example, largestring guaranteed contain single set of ###### 's (6 hash characters). how can insert smallstring between it, ending similar (i guess better 'create string', since strings immutable): largestring = "lorem ipsum ###### previous text erased ###### dolor sit amet" smallstring = "foo bar" newstring = "lorem ipsum ###### foo bar ###### dolor sit amet" any ideas? assume use bit of regex... something like >>> import re >>> largestring = "lorem ipsum ###### previous text erased ###### dolor sit amet" >>> smallstring = "foo bar" >>> re.sub(r'(?<=###### ).*(?= ######)', smallstring, largestring) lorem ipsum ###### foo bar ###### dolor sit amet' (?<=###### ) postive b...

i worked entity framework several years ago, , may me being bit rusty. have detached entities, in turn have multiple child entities. in case it's person entity , each person has multiple addresses. myperson.firstname="update first name"; //assuming have address in first entry //with appropriate primary keys , foreign key ids, do: myperson.addresses.first().line1="update line 1"; myperson.addresses.add(new address(){line1="weee",line2="aaaa" postal="12345", type="work"}); mydb.person.attach(myperson); mydb.entry(myperson).state=entitystate.modified; mydb.savechanges(); when scenario this, expect first name. updates first name, , expected blanks out other fields (lastname, birthday etc etc) in above code. doesn't create new address person, nor update existing address. i don't recall requiring work database context know how update related entities associated person above. in google searches seem hearin...
