playframework - Displaying a list of checkboxes in my form -


i want display many checkboxes inline like:

<label class="checkbox-inline">   <input type="checkbox" id="inlinecheckboxa" value="optiona"> </label> <label class="checkbox-inline">   <input type="checkbox" id="inlinecheckboxb" value="optionb"> b </label> <label class="checkbox-inline">   <input type="checkbox" id="inlinecheckboxc" value="optionc"> c </label>

so have form like:

val form: form[searchform] = form(   mapping(     "letters" -> list(text)   )

)(searchform.apply)(searchform.unapply _)

can somehow pre-populate form data or have pass variable view has 'letters' data?

val letters = list[string]("a", "b", "c", ...)

if can't pass letters val down view, guess pass variable model , iterate on it?

have looked @ helper inputcheckboxgroup ?

that pre-populated form elements model you'll still have provide checkbox group set of possible values.

for example: 

@views.html.helper.inputcheckboxgroup(   form("letters"),   options = seq("a" -> "alpha", "b" -> "beta", "c" -> "gamma"),   '_label -> "my cool checkbox" )

and form filled with: 

val form: form[simpleform] = form(mapping(     "letters" -> list(text)   )(simpleform.apply)(simpleform.unapply))  simpleform.form.fill(simpleform(list("a", "b")))

would render checkbox group this:

[x] alpha [x] beta [ ] gamma

vue.js - Create hooks for automated testing -

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 ...
