gorm - Issues with GRAILS UUID and PSQL -

-

i trying use uuid2 generator on grails 2.4.4, psql version 9.4.4. current model setup is.

class classa {     uuid id     static mapping = {        id generator:'uuid2', name:'uuid2', type:'pg-uuid'        tableperhierarchy false    } }

and

class classb extends classa {      static constraints = {     }      static mapping = {     } }

but when perform run-app error.

error context.grailscontextloaderlistener - error initializing application: error evaluating orm mappings block domain [classb]: null message: error evaluating orm mappings block domain [classb]: null

any ideas did wrong?

rename uuid id uuid uuid2 or remove name: uuid2. far know name in mapping assign id generator 1 of properties.

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 .
