Is there a way to store a custom expression in Firebase Rules to be reused? -

-

i able reuse expression in firebase rules multiple times.

if have following rules: 

{   "rules": {     ".read": true,     ".write": false,     "secretarea1": {       ".read": "root.child('users').child(auth.uid).child('role').val() === 'admin'",       ".write": "root.child('users').child(auth.uid).child('role').val() === 'admin'"     },     "secretarea2": {       ".read": "root.child('users').child(auth.uid).child('role').val() === 'admin'",       ".write": "root.child('users').child(auth.uid).child('role').val() === 'admin'"     }   } }

is there way store root.child('users').child(auth.uid).child('role').val() === 'admin' somewhere doesn't have repeated 4 times?

something like:

{   "rules": {     ".read": true,     ".write": false,     "secretarea1": {       ".read": "isadmin",       ".write": "isadmin"     },     "secretarea2": {       ".read": "isadmin",       ".write": "isadmin"     }   } }

maybe i'm approaching wrong way. suggestions great!

i discovered blaze compiler linked @ security & rules libraries. not looking , adds compile step seems provide functionality looking for. nice if included option in firebase dashboard.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
