i'm doing rather simple insert local mongodb sourced of python pandas dataframe. i'm calling datframe.loc[n].to_dict() , getting dictionary directly df. far until attempt insert, i'm getting 'cannot encode object'. looking @ dict directly showed looked (while writing question) dawned me check each type in dict , found long id number had converted numpy.int64 instead of simple int (which when created dict manually int insert fine). so, unable find within pandas documentation on adding arguments to_dict allow me override behavior , while there brute force methods fixing issue, there must bit more eloquent way sort issue without resorting sort of thing. question then, how convert row of dataframe dict insertion mongodb, ensuring using acceptable content types ... or, can further here , use simpler approach each row of dataframe document within mongo? thanks as requested, here addendum post sample of data using. {'account created': 'about 3 hou...
