Storing a custom Python object in Redis -


i'm trying store custom, serializable python object in redis, have encountered strange behavior. set method seems function, get method returns value of object's __repr__ method. instance...

import redis  # initialize redis connection pool rs = redis.redis(host='localhost', port=6379)  # define custom class class somecustomobject(object):     pass

when try set somecustomobject value, appears work:

>>> rs.set('c', somecustomobject()) true

however, when get value back, it's __repr__ string:

>>> rs.get('c') '<__main__.somecustomobject object @ 0x102496710>'

how store/get instance back? i've not had luck finding info on in the documentation, surely i'm not first 1 encounter this?

use pickle

using pickle module can serialize , deserialize python objects , pass them redis.

from answer - https://stackoverflow.com/a/20400288/4403600, this:

import pickle import redis  # define custom class class somecustomobject(object):     pass  # initialize redis connection pool rs = redis.redis(host='localhost', port=6379)  # pickle , set in redis rs.set('c', pickle.dumps(somecustomobject()))  # redis , unpickle unpacked_object = pickle.loads(rs.get('c'))

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.

java - How to provide dependency injections in Eclipse RCP 3.x? -

everyone! i'm trying deal eclipse rcp 3.x application. i've read lot of articles dependency injection in rcp e4 applications. can use di in rcp 3.x apps? i found perfect link di in e4. idea how use in rcp 3.x app? first of all, i'm interested in own objects injection (btw, how add own object application context?). best regards in 3.x code can ieclipsecontext necessary use contextinjectionfactory using ieclipsecontext workbenchcontext = platformui.getworkbench().getservice(ieclipsecontext.class); to workbench context. in view or editor can current part context using: ieclipsecontext partcontext = getsite().getservice(ieclipsecontext.class);
