ember.js - cp-validation not working as expected -


i integrating cp-validaiton ember app. not getting response. 1 me here.

my route js :

import ember 'ember'; import validations '../validation'  export default ember.route.extend(validations, {   num:null,     message: '',   model(){     return { num:null}   },   actions:{      check(){         this.set('message','');        this.validate().then(({model, validations})=>{         if(validations.get('isvalid')){           console.log('statge', validations.get('isvalid') )                     this.set('message','');                 }else{         if(model.get('validations.attrs.num.isinvalid')){                         this.set('message',model.get('validations.attrs.num.messages'));                     }         }       })     }   } });

my validation.js :

import { validator, buildvalidations } 'ember-cp-validations';  export default buildvalidations({     num: [         validator('number',{         allowstring: true,         integer: true,         message: 'error! not integer!' }),     validator('presence', true) ] });

template :

<h1>this route</h1>  enter age:<br> {{input value=model.num}}<br> <div style='color: red'>{{message}}<br></div> <button {{action 'check'}}>check</button><br>

live in twiddle

validations must defined upon data object, which, in case, not route's attribute underlying controller's model. controller's model set ember in setupcontroler() hook of route.

thus use nested keys approach target validations set upon correct data:

import { validator, buildvalidations } 'ember-cp-validations';  export default buildvalidations({     'controller.model.num': [         validator('number',{         allowstring: true,         integer: true,         //message: 'error! not integer!' }),     validator('presence', true) ] });

note: attribute definition

export default ember.route.extend(validations, {   num:null, // not used, confusing :)   message: '',   .... }

is unnecessary , confusing since not used, feel free remove it.

checking validity / errors etc. on attribute basis can achieved follows:

 model.get('validations.attrs.controller.model.num.isvalid');  model.get('validations.attrs.controller.model.num.errors');  model.get('validations.attrs.controller.model.num.messages');

your route this:

import ember 'ember'; import validations '../validation'  export default ember.route.extend(validations, {   model(){     return { num:null}   },   actions:{      check(){         this.set('controller.message','');        this.validate().then(({model, validations})=>{         if(validations.get('isvalid')){            this.set('controller.message','');         }else{      if(model.get('validations.attrs.controller.model.num.isinvalid'){             this.set(               'controller.message',                model.get('validations.attrs.controller.model.num.messages.firstobject'));          }         }       })     }   } });

however, recommend migrating validations-related code model instead of building them in route. it's more logical, readable, lets decrease size of code, , fits find in ember-cp-validations docs.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
