node.js - PostGIS query with NodeJS, BookshelfJS and Knex -


i'm on project nodejs, bookshelfjs , expressjs. database postgres postgis installed. table 'organizations' has 'lat_lon' geometry column. query organization within fixed radius of specific lat/long point. tried this:

var organizations = await organization.query(function (qb) {  qb.where('st_dwithin(lat_lon, st_geomfromtext("point(45.43 10.99)", 4326), 1000 )')  }).fetchall()

and more combinations doesn't work. returns me error

unhandledpromiserejectionwarning: unhandled promise rejection (rejection id: 1): typeerror: operator "undefined" not permitted

it seems expecting operator inside condition i'm working on 'lat_lon' column.

how can fix it? thanks

have tried using knex.raw()?

var organizations = await organization.query(function (qb) {  qb.where(knex.raw('st_dwithin(lat_lon, st_geomfromtext("point(45.43 10.99)", 4326), 1000 )')) }).fetchall()

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
