jsf - How to use h:selectOneRadio in h:dataTable to select single row? -

-

i have list of pages displayed in table. each page has property homepage , want in datatable have column of radio buttons binded on property, , user can check 1 value. how can value on server side?

i saw examples following: http://jforum.icesoft.org/jforum/posts/list/14157.page, know best practice in such case.

as per jsf spec issue 329 have implemented jsf 2.3. new group attribute able group radio buttons in repeater component.

<h:datatable value="#{bean.items}" var="item">     <h:column>         <h:selectoneradio group="foo" value="#{bean.selecteditem}">             <f:selectitem itemvalue="#{item}" />         </h:selectoneradio>     </h:column> </h:datatable>

it available per mojarra 2.3.0-m07.

before jsf 2.3, not trivial standard jsf <h:selectoneradio>. basically, radio button in every row needs grouped each other using same input name other radio buttons unchecked whenever select one. not been grouped, have own name, other radio buttons never unchecked.

component libraries primefaces have solved providing special attribute or column component. see this showcase example uses <p:column selectionmode="single"> generate single selection column. selected value referenced selection attribute of <p:datatable>. if you're using component library , has such component you, should use it.

in standard jsf <h:datatable> <h:selectoneradio> you'd need bring in javascript workaround follows unchecks other radio buttons in same column:

<h:datatable value="#{bean.items}" var="item">     <h:column>         <h:selectoneradio valuechangelistener="#{bean.setselecteditem}"             onclick="datatableselectoneradio(this);">             <f:selectitem itemvalue="null" />         </h:selectoneradio>     </h:column>     ... </h:datatable>

with

public void setselecteditem(valuechangeevent event) {     facescontext context = facescontext.getcurrentinstance();     selecteditem = context.getapplication().evaluateexpressionget(context, "#{item}", item.class); }

and

function datatableselectoneradio(radio) {     var radioid = radio.name.substring(radio.name.lastindexof(':'));      (var = 0; < radio.form.elements.length; i++) {         var element = radio.form.elements[i];          if (element.name.substring(element.name.lastindexof(':')) == radioid) {             element.checked = false;         }     }      radio.checked = true; }

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...
