let's have series of tables in mysql, , of them dependent on other tables (so if didn't want force delete, have delete them in order). let's had little script delete them in order...now let's wanted run in mysql workbench, , better yet have function took in parameter (like userid) , did above... how such thing in mysql workbench in way retrieve , run code (like example if wanted delete user , other objects associated user.) you can use stored procedure delimiter // create procedure delete_user(in _user_id int) begin start transaction; delete user_data user_id = _user_id; -- other delete statements go here in proper order delete users id = _user_id; commit; end// delimiter ; sample usage: call delete_user(2); -- delete user id = 2 here sqlfiddle demo

i using jackson parsing parse json , saving hbase . prior save have validate datatype of nodes against list of datatypes mysql. following approach: def validatenode(node:jsonnode, datatype : string) :any = { val nodevalue = node.tostring() datatype.tolowercase() match { case "double" ⇒ { try{ d.todouble } catch{ } } case "int" ⇒try { node.getvalueasint } catch{} case "string" ⇒ try{ node.gettextvalue }catch{} } } which looks ugly me. a) catching exceptions in every case block see whether datatype correct. can suggests me elegant code this? further, have handle datatypes array , vector too. eg : jsonnode {"a":[[1,2],[2,4],[4,5]]} (==>vector of integer) .

how download previous version of werkzeug trusted site? here have tried: 1) went link: http://werkzeug.pocoo.org/docs/0.9/installation/#installing-a-released-version , clicked on "download page" link. it took me 0.10.4 download page. 2) googled "werkzeug download 0.9" , got references 0.10. there download link versioneye.com site don't know if can trust. i need download previous version because 0.10.x dropped support support openssl. [edit] have download rather install pip because don't have access pip on old machine installing on. old, hence complications. [edit] had use older version because 0.10.x dropped support openssl package in favor of ssl built python 2.7.9. stuck on python 2.7.5 wanted continue use openssl package. think made right decision drop support majority of people can upgrade 2.7.9. you can install old package pip: pip install werkzeug==0.9.6

i have 2d numpy array column 0 pan rotation of device , column 1 tilt rotation. each row different fixture. want run following logic on each row: if(pantilt[0] > 90): pantilt[0] -=180 pantilt[1] *= -1 elif pantilt[0] < -90: pantilt[0] += 180 pantilt[1] *= -1 i understand basic conditional operations on 1d myarray[condition] = something. can't extrapolate more dimensions. i calculate mask, or boolean index, , use if each column: construct sample array: pantilt=np.column_stack([np.linspace(-180,180,11),np.linspace(0,90,11)]) = pantilt[:,0]>90 # j = pantilt[:,0]<-90 pantilt[i,0] -= 180 pantilt[i,1] *= -1 = pantilt[:,0]<-90 # use j instead pantilt[i,0] += 180 pantilt[i,1] *= -1 before: array([[-180., 0.], [-144., 9.], [-108., 18.], [ -72., 27.], [ -36., 36.], [ 0., 45.], [ 36., 54.], [ 72., 63.], [ 108., 72.], [ 144., 81.], [ 180., ...

i using on rails 4 , activeadmin, batch action collection form capture input user perform batch action ( in case batch mailer). there way customize labels inputs? say example: batch_action :email, priority: 1 , form: {main_subject: :text, message: :textarea } |ids, inputs| batch_action_collection.find(ids).each |user| contactbatchmailer.contact_batch_email(main_subject, message,... instead of having "main_subject", display better formatted text, "main subject", or better, more descriptive variable name itself. i dug in documentation https://github.com/activeadmin/activeadmin/blob/master/docs/9-batch-actions.md#batch-action-forms not able to. suggestions appreciated. the form rendered modal_dialog.js.coffee, should possible override , customize, example see declined pull request @mmustala
