javascript - Meteor and React not output data correctly. -


so trying output data paint , getting [object,object]. tried adding .tostring() no luck. appreciated.

i know means there objects inside of arrays don't know generating array and/or how reformat that.

class paintpage extends component { constructor(props) {     super(props);     this.state = {};      this.handlesubmit = this.handlesubmit.bind(this);     //brads cool }  handlesubmit(e) {     e.preventdefault();      paint.insert({         brand: this.refs.brand.value,         color: this.refs.color.value,         sheen: this.refs.sheen.value,         room: this.refs.room.value     }); }  render() {     var paintarr = paint.find().fetch();     paintarr.map((room, index) =>         <div classname="row">             <div classname="col-xs-2">                 <li classname="list-group-item text-center" key={room}>                     {paintarr}                 </li>             </div>         </div>     );      return (         <div>             <div classname="row">                 <div classname="col-xs-4">                     <productnav />                 </div>             </div>             <form classname="form" onsubmit={this.handlesubmit}>                 <div classname="row">                     <div classname="col-xs-4" />                     <div classname="col-xs-4">                         <label htmlfor="brand" classname="input">                             paint brand                         </label>                         <div classname="field">                             <input                                 type="text"                                 name="brand"                                 classname="form-control"                                 placeholder="brand/company"                                 ref="brand"                                 value={this.props.value}                                 onchange={this.props.onchange}                             />                         </div>                     </div>                 </div>                 <div classname="row">                     <div classname="col-xs-4" />                     <div classname="col-xs-4">                         <label htmlfor="color" classname="input">                             color                         </label>                         <div classname="field">                             <input                                 type="text"                                 name="brand"                                 classname="form-control"                                 placeholder="color"                                 ref="color"                                 value={this.props.value}                                 onchange={this.props.onchange}                             />                         </div>                     </div>                 </div>                 <div classname="row">                     <div classname="col-xs-4" />                     <div classname="col-xs-4">                         <label htmlfor="brand" classname="input">                             sheen                         </label>                         <div classname="field">                             <input                                 type="text"                                 name="brand"                                 classname="form-control"                                 placeholder="sheen"                                 ref="sheen"                                 value={this.props.value}                                 onchange={this.props.onchange}                             />                         </div>                     </div>                 </div>                 <div classname="row">                     <div classname="col-xs-4" />                     <div classname="col-xs-4">                         <label htmlfor="room" classname="input">                             room                         </label>                         <div classname="field">                             <input                                 type="text"                                 name="room"                                 classname="form-control"                                 placeholder="room"                                 ref="room"                                 value={this.props.value}                                 onchange={this.props.onchange}                             />                         </div>                     </div>                 </div>                 <div classname="row">                     <div classname="col-xs-12"> </div>                     <input                         classname="btn btn-primary btn-lg button-buffer"                         type="submit"                         value="input"                     />                 </div>             </form>             <div>                 <div>                     <ul classname="list-group">                         {paintarr.tostring()}                     </ul>                 </div>             </div>         </div>     ); } }  export default paintpage;

you printing whole array because use variable {paintarr} instead of current element of map function. should (assuming want print color):

var painter = paint.find().fetch();     paintarr.map((entry, index) =>         <div classname="row">             <div classname="col-xs-2">                 <li classname="list-group-item text-center" key={entry.room}>                     {entry.color}                 </li>             </div>         </div>     );

note key={room} key={entry.room} because room attribute of current element in array.

if still don't know going on here, may further research array.map function , how works.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
