c# - Unable to retrieve metadata for 'JMAP.Models.tempSource'. Keyword not supported 'data source' -

-

i using visual studio 2010 , entityframework version 5.0.0.0 trying create controller 'tempsource' table in oracle 11.2 , getting following error.

this code entity.

namespace jmap.models {

public class tempsource {                    public string systemname { get; set; }     public string systemdesc { get; set; }     public string userid { get; set; } }  public class tempsourcedbcontext : dbcontext {     public dbset<tempsource> tempsources { get; set; } }

}

add name="tempsourcedbcontext" connectionstring="user id=user_id;password=pwd;datasource=(description = (address_list = (address = (protocol = tcp)(host = hostname)(port = portnumber))) (connect_data = (service_name = dbname)))"

providername="system.data.oracleclient"

and have added above connection string in web.config file.

can me error.

it bad! following wrong approach. using code-first approach whereas wanted use data-first approach,but being new mvc , c# , got confused.

if needs mvc , beginner me, can go through following website databse design approaches. pretty useful.

http://www.asp.net/mvc/overview/getting-started/database-first-development/generating-views

moreover, can go through these videos, bit time consuming, gives understanding of mvc.

hope helps!

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
