Dears,

As you know t-field gives fields access via browsable record.

For the survey module, it's used on survey qweb template. For example, for the survey_init template (the first page of every started survey, describing survey title, and description) here is the code using t-field : 

 <template id="survey_init" name="Survey"> 

     <t t-call="website.layout"> 

         <div class="wrap"> 

             <div class="oe_structure" /> 

                 <div class="container"> 

                     <div groups="base.group_website_publisher" t-ignore="true" class="text-right"> 

                         <a href="/web#action=survey.action_survey_form" class="btn btn-default">Go back to su                            rveys</a> 

                      </div> 

                      <div class='jumbotron mt32'> 

                          <h1 t-field='survey.title' /> 

                          <div t-field='survey.description' class="oe_no_empty"/> 

                          <a class="btn btn-primary btn-lg" t-att-href="'/survey/fill/%s/%s' % (slug(survey                                ), token)"> 

                                 Start Survey 

                             </a> 

                         </div> 

                     </div> 

                 <div class="oe_structure" /> 

             </div> 

         </t> 

 </template>

So how this is can be done ?

Humble answer : After inspecting the controllers code, it's the start_survey() method that is responsible of launching the survey, it takes the variable survey as a parameter, and send it via data dictionnary trough : website.request.render, wich allows access survey fields value using t-field.

Here is the code part (For one page rendering case "test survey" among others) explainig that : 

 @http.route(['/survey/start/<model("survey.survey"):survey>', 
 '/survey/start/<model("survey.survey"):survey>/<string:token>'], 
 type='http', auth='public', website=True) 
 def start_survey(self, survey, token=None, **post): 
 cr, uid, context = request.cr, request.uid, request.context 
     survey_obj = request.registry['survey.survey'] 
     user_input_obj = request.registry['survey.user_input'] 
     # Test mode 
     if token and token == "phantom": 
         _logger.info("[survey] Phantom mode") 
         user_input_id = user_input_obj.create(cr, uid, {'survey_id': survey.id, 'test_entry': True}, context=context) 
         user_input = user_input_obj.browse(cr, uid, [user_input_id], context=context)[0] 
         data = {'survey': survey, 'page': None, 'token': user_input.token} 
     return request.website.render('survey.survey_init', data)

My question here is how survey is passed as a parameter ? is it by using @route ?

If I know how to pass more parameters to start_survey(), then maybe I can pass a parameter named like "survey_user_input" trough data dictionnary, allowing me to use it on t-field.

NB:

I'm calling my survey from hr_evaluation_interview model from the hr_evaluation module.

Here is the method calling survey from hr_evaluation module (maybe I can use it to pass a parameter to start survey via context) : 

 def action_start_survey(self, cr, uid, ids, context=None): 
 ''' Open the website page with the survey form ''' 
     trail = "" 
     context = dict(context or {}, relative_url=True) 
     if 'survey_token' in context: 
         trail = "/" + context['survey_token'] 
     return { 
         'type': 'ir.actions.act_url', 
         'name': "Start Survey", 
         'target': 'self', 
         'url': self.read(cr, uid, ids, ['public_url'], context=context)[0]['public_url'] + trail 
         }

I hope my question is clear, if not, I'm here for further explainations.

Many thanks for your help.

The argument survey is converted and passed by the @route decorator, converting the positional param of the url to a model object using a model argument pattern converter declared in the url param of the @route decorator and passed to the handle method of the url. 

See more here about that:

https://www.odoo.com/documentation/8.0/howtos/website.html#urls-and-routing

Specifically:

Odoo provides an additional converter called model which provides records directly when given their id. Let's use this to create a generic page for teacher biographies:

So you need to redefine the method and the @route url pattern and the method arguments to match the url pattern.

The url returned on the method action_start_survey need to match the @route url pattern so add the id value of the survey_user_input param to the url obtained from the field public_url or to the trail var, the thing is that the result url need to match the url for the @route overrided

Thanks a lot Axel for your explainations, I'm now trying to override : action_start_survey method called from hr_interview (I did'nt included it on my post), it's the first called method, that calls action_start_survey of the survey model. (So functionnaly speaking, it's like using action_start_survey for a human ressources evaluation purpose). Then I'll override action_start_survey of the survey module, and then override @route decorator and start_survey() method. I'll post my code, and further details soon. Thanks for your valuable help.

Hi Axel, it worked : On the first action_start_survey (on hr_interview object) I had to pass a browsable record of it, using context, and then on action_start_survey(survey object), modify trail, and add slug(context['interview']) to the url, and finally on the start_survey() method override @route decorator and pass the parameter, then send it via data dictionnary to the qweb view, and it's ready to use. I have to do the same for print_survey() and fill_survey(). Thanks a lot Axel for your help.
