Using some reflection and generics in two extension methods you can achieve that. Right, others did mostly the same solution, but this uses less reflection which is more performance-wise and way more readable: public static class ObjectExtensions { public static T ToObject<T>(this IDictionary<string, object> source) where T : class, new() { var someObject = new … Read more
You’ve really got 3 different things going on here. 1 & 3. Drives are only mapped when you log on interactively. So when you remoted into the other computer, mapped a drive, and then logged off/disconnected, that mapped drive was disconnected. Except in interactive GUI user sessions, you cannot depend upon a mapped drive letter … Read more
The __getitem__() and keys() methods will suffice: >>> class D: def keys(self): return [‘a’, ‘b’] def __getitem__(self, key): return key.upper() >>> def f(**kwds): print kwds >>> f(**D()) {‘a’: ‘A’, ‘b’: ‘B’}
remap is an option that makes mappings work recursively. By default it is on and I’d recommend you leave it that way. The rest are mapping commands, described below: :map and :noremap are recursive and non-recursive versions of the various mapping commands. For example, if we run: :map j gg (moves cursor to first line) … Read more
Python 2: res = dict((v,k) for k,v in a.iteritems()) Python 3 (thanks to @erik): res = dict((v,k) for k,v in a.items())
A nested dict is a dictionary within a dictionary. A very simple thing. >>> d = {} >>> d[‘dict1’] = {} >>> d[‘dict1’][‘innerkey’] = ‘value’ >>> d[‘dict1’][‘innerkey2’] = ‘value2’ >>> d {‘dict1’: {‘innerkey’: ‘value’, ‘innerkey2’: ‘value2’}} You can also use a defaultdict from the collections package to facilitate creating nested dictionaries. >>> import collections >>> … Read more
Why is the notion of a owning side necessary: The idea of a owning side of a bidirectional relation comes from the fact that in relational databases there are no bidirectional relations like in the case of objects. In databases we only have unidirectional relations – foreign keys. What is the reason for the name … Read more
Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices. You haven’t shown us the … Read more
Here’s the answer I found: Just to make the definition complete, in the Cartesian coordinate system: the x-axis goes through long,lat (0,0), so longitude 0 meets the equator; the y-axis goes through (0,90); and the z-axis goes through the poles. The conversion is: x = R * cos(lat) * cos(lon) y = R * cos(lat) … Read more
