Thanks!
web2py doesn't work quite like that. Before proceeding, I suggest you read some of the introductory documenation as well as the documentation on forms.
If you submit a form to a web2py URL, the function that handles that URL can access the form variables in request.vars (also, request.post_vars if submitted via POST and request.get_vars if submitted via GET). In the case of your code, you would need to add a "name" attribute with the value "lang" to the <select> element, in which case, the receiving action could access the value via request.vars.lang. You controller action itself should not take any arguments.
Instead, though, you might find it easier to use web2py's built in forms functionality as noted above.

So I have this project, and I want to return an object, from the previous choice of 2 select items. How can I do it? for example:
<select class="form-control" id="cityPicker1">
<option value="0">select option</option>
<option th:each="city: ${listCities}" th:value="${city.number}" th:text="${city.name}"></option>
</select>
<select class="form-control" id="cityPicker2">
<option value="0">select option</option>
<option th:each="city: ${listCities}" th:value="${city.number}" th:text="${city.name}"></option>
</select>
I want to display an item from another item list which has a number1 field and a number2 something like ticket.number1 and ticket.number2 but they have to match the values from the previous selects. I can't seem to find anything. Any ideas?
This is how I set it up in the controller:
#GetMapping("/tickets")
public String viewTicketsPage(Model model) {
List<City> listCities = cityRepo.findAll();
List<Ticket> listTickets = ticketRepo.findAll();
model.addAttribute("listCities", listCities);
model.addAttribute("listTickets", listTickets);
return "tickets";
}
I need to clarify a few things about your question.
1 - did you manage to get the checkboxes to work?
2 - can you send the selected data to the controller?
you need a controller to receive data from the page, send this data to the repository to fetch other data..
I believe you want to select a table, where the data matches the selected ones. .
take a look at JPQL, maybe this will help you:

I am asking for help. Is there any way I could fill an input box based on drop down selection? On my modal I have a dropdown option for subject description and I would like the subject number input field dynamically change its value. Any help would be much appreciated.
This is how I retrieved the data for my dropdown
subjects=DB::table('programs_subj')->select('corsdes', 'corsno')->get()
This is my dropdown code for the subject description which is working and the selected is saved but I could quite how to incorporate the subject number
<select name="corsdes" id="corsdes" wire:model="corsdes">
<option value="corsdes" wire:model="corsdes"></option>
#foreach($subjects as $sbj)
<option value="{{ $sbj->corsdes }}">{{ $sbj->corsdes}}</option>
#endforeach
</select>
<input name="corsno" id="corsno" wire:model="corsno"><input>
if you have the public properties $corsdes and $corsno then:
public function updatedCorsdes($value)
{
$this->corsno = $this->subjects->where('corsdes',$value)->first()->corsno;
}
I try to made nested form with validation. All works fine, but when I remove one of nested form, validation continue to use removed form. I made jsfiddle example http://jsfiddle.net/sokolov_stas/VAyXu/
When example runs, form are valid. If click "+" button, nested form will be added and valid will be false. Then click "-" button, and valid will be false all the same.
The question is: How to remove dynamic created form from validation processing.
Well, for one thing, a <form> inside of a <form> is not valid HTML.
Second, you're not supposed to be doing DOM manipulation from inside the controller. The controller is for "business" logic. See the section on controllers here
For what you're doing, you'd probably be better off using one form, with an ng-repeat inside of it, and adding additional elements to an array:
<form name="myForm" ng-controller="FormCtrl" ng-submit="doSomething()">
<div ng-repeat="item in items">
<input ng-model="item" type="text" required/>
</div>
<a ng-click="addItem()">+</a>
<a ng-click="removeItem()">-</a>
<button type="submit">Submit</button>
<div>Form valid: {{myForm.$valid}}</div>
</form>
and the controller:
function FormCtrl($scope) {
$scope.items = [];
$scope.addItem = function() {
$scope.items.push(null);
};
$scope.removeItem = function() {
$scope.items.pop();
};
$scope.doSomething = function () {
//your submission stuff goes here.
};
}
I'm attempting to get a dropdown list to select the correct value when the page loads.
#Html.DropDownList("CounterpartyTypeSelect", new SelectList(ViewBag.CounterpartyTypeOptions, "DefaultId", "Value"), new { #class = "selectbox", selected = Model.CounterpartyType })
However, when the page renders it always selects the first value in the dropdown list.
The html source for the page:
<select class="selectbox" id="CounterpartyTypeSelect" name="CounterpartyTypeSelect" selected="977980f2-ebb2-4c2a-92c2-4ecdc89b248d">
<option value="5802239e-c601-4f1e-9067-26321213f6e6">Societa per Azioni (SpA)</option>
<option value="f8160341-4a69-436f-9882-4da31a78f1d5">Gesellschaft mit beshrankter Haftung (GmbH)</option>
<option value="977980f2-ebb2-4c2a-92c2-4ecdc89b248d">Sociedad Anonima (SA)</option>
<option value="cdbeb1d3-301b-4884-b65a-612ddd8306f3">Private Limited Company (Ltd)</option>
<option value="1fe68d96-f31b-4859-9869-8c76a5eb1508">Corporation (Inc)</option>
<option value="9c9e5722-ab59-4d1c-a0a3-91b42a3ee721">Limitada (LTDA)</option>
<option value="0cb57339-8705-4e3a-8f6a-95e9664962b7">Public Limited Company (Plc)</option>
<option value="0924d6f1-06a9-49a3-ac05-b3e2686a0e92">Partnership</option>
<option value="c8fbe021-a8f7-4e9d-ab38-dbeb5af5a631">Limited Liability Company (LLC)</option>
<option value="30d9e22b-34f5-43c5-8471-e614dbedb6a6">Aktiengesellschaft(AG)</option>
</select>
As you can see it is putting the "selected" attribute into the outer select tag instead of on the option that matches the Id. I have another select with identical parameters (except variable names of course) and it renders correctly this way. I do not want to use DropDownListFor<T> because I have a HiddenFor field that actually submits this value in the form and javascript that sets the value to match the Select choice. I've confirmed my database is storing the values that I set correctly. What is going on?
SelectList() has an overload for you to choose the selected item. You are adding it as an HTML attribute in the helper and those get rendered to the parent select tag.
Do this:
#Html.DropDownList("CounterpartyTypeSelect", new SelectList(ViewBag.CounterpartyTypeOptions, "DefaultId", "Value", Model.CounterpartyType), new { #class = "selectbox" })
Use the overload for SelectList that takes four arguments:
new SelectList(IEnumerable items, string dataValueField, string dataTextField, object selectedValue);
What's happening in the first line of your code new { #class = "selectbox", selected = Model.CounterpartyType } is you're providing the selected attribute as an HTML attribute of the parent select element.
So you see selected="977980f2-ebb2-4c2a-92c2-4ecdc89b248d" appearing in your first line of output, which btw doesn't do anything.
Also you're providing the value to search for in the Helper as a hardcoded string "value" instead of the actual value you need from the model. The browser will default to the first option since it can't find any value matching 'value'.
To fix this, provide Model.CounterpartyType as the third parameter to your SelectList parameter instead of 'value'.
<select id="selectedSchool" size="3" multiple="multiple" name="selectedSchool">
#foreach (var item in ViewBag.pt)
{
<OPTION VALUE="#item.entityID">#item.name</OPTION>
}
</select>
on my page the user selects a school from the list of schools, each school has a unique ID which is needed and passed via the VALUE attribute, I also would like to pick up the name
(item.name) that was selected how can I resolve this info from my control Action Result?
public ActionResult ResultsSchoolsAttended(List<int> selectedSchool)
i iterate through the list of results, but I would aslo like selectedSchool.name to enter back in the db as 'display text'
how can i do this?
Well, MVC can only give you what is in the HTTP POST. And if you look at that, you will see that the <option> inner HTML isn't there. So you have only two choices:
Include it in the value in your markup, or
Look it up in your ResultsSchoolsAttended action based on the submitted value.
I'd pick the second, personally.
