將記錄集傳遞給控制器​​Odoo模板中的對象

Question

我在Odoo網站上有一個表單，其中有國家和州選擇字段。這種形式是由一個控制器填充的，我將所有州和國家的記錄集作爲一個字典中的國家和國家作爲關鍵字來傳遞。現在對於選擇字段，它使用t-foreach通過狀態循環以提供選項和值。現在選擇國家後，我需要能夠過濾出該國的狀態。這是可能的，如果是的話，怎麼樣？下面是其中一些我已嘗試的代碼： 以下是其中最初加載的形式，並且所述第二方法，所述控制器被過濾掉的狀態

@http.route('/admission_applications', type='http', auth="public", website=True) 
def application_form(self): 
    cr, uid, context, registry = request.cr, request.uid, request.context, request.registry 
    classes=[('lkg',"LKG"),('ukg',"UKG"),('1', "1st"), ('2', "2nd"),('3', "3rd"),('4', "4th"),('5', "5th"),('6', "6th"),('7', "7th"),('8', "8th"),('9', "9th"),('10', "10th"),('11', "11th"),('12', "12th")] 
    gender=[('male', "Male"), ('female', "Female")] 
    orm_country = http.request.env['res.country'] 
    state_orm = http.request.env['res.country.state'] 
    countries = orm_country.search([]) 
    #countries = orm_country.browse(cr, SUPERUSER_ID, country_ids, context) 
    states = state_orm.search([]) 
    #states = state_orm.browse(cr, SUPERUSER_ID, states_ids, context) 
    return request.render("website_admission_application.admission_form", {'classes':classes, 'gender':gender, 'countries':countries, 'states':states}) 



@http.route('/action_get_states/<country_id>',type='http', auth="public", website=True) 
def states_listing(self,country_id): 
    states_info=[]  
    logging.error(country_id) 
    states=http.request.env['res.country.state'].search([('country_id.id','=',country_id)]) 
    for state in states: 
     states_info.append({'id':state.id, 'name':state.name}) 


    logging.error(states_info)  
    return states_info 

接下來就是模板相關的代碼：

<div t-attf-class="form-group form-field o_website_form_required_custom margin-0" t-if="countries"> 
    <div class="col-sm-12 col-md-6"> 
    <label class="control-label" for="country_id">Country</label> 
    <select name="country_id" id="country_id" class="form-control" onchange="countryselection()" required=""> 
     <option value="">Country...</option> 
     <t t-foreach="countries" t-as="country"> 
      <option t-att-value="country.id"><t t-esc="country.name"/></option> 
     </t> 
    </select> 
    </div> 
    <div class="col-sm-12 col-md-6"> 
     <label class="control-label" for="state_id">State</label> 
     <select name="state_id" id="state_id" class="form-control" required=""> 
      <option value="">State...</option> 
      <t t-foreach="states" t-as="state"> 
       <option t-att-value="state.id"><t t-esc="state.name"/></option> 
      </t> 
     </select> 
    </div> 
</div> 

的JS調用控制器的方法來過濾狀態是這樣的：

function countryselection() { 
    alert("hai"); 
    var country = document.getElementById('country_id').value; 
    alert(country); 
    $.ajax({ 
     type: "GET", 
     url: "/action_get_states/"+country, 
     success: function(data) { 
      $("states").html(data); 
     } 
    });  
} 

我知道這是不正確的做法，但我ñ確信我可以如何將記錄集返回到已經使用表單初始加載的狀態。

//This is just an example which I used on Odoo website. 
// Just make your proper changes by changing field names.  
$(document).ready(function() { 

     $('select[name=country_id]').change(function() { 
     $('#state_id option').remove(); 
     var states = new Model('res.country.state').call('search_read',[[['country_id', '=', parseInt($('select[name=country_id]').val())]]]).then(function(result){ 
     for (var i=0; i<result.length; i++){ 
      $('#state_id').append($('<option>', 
       { 
        value: result[i].id, 
        text : result[i].name 
       })); 
     } 
     }) 

     });
