Odoo : Make changes on Survey module

Question

I am working on editing the survey module in odoo. When I answer a survey which is composed of pages and then click on submit survey, it calculates the whole score of the survey and displays it. What I want is that it calculates the score of each page and display it when I click on submit survey for example:

It displays: Your score is: 200 points.
And I want it to display: Score of first page : 20 points, Second page: 50 points and so on...

Here is the code that I want to change but I don't know how should I change this function.

Answer 1

Thank you so much @MICROCOM .. The line that display the score for each page is diplayed more than once ..

The result Of The code - 1

So i added a condition to just display the score of a certain page once (I don't know if it's correct but it works :p ) .. Here is the code :

<!-- First finding which page is related to the survey. This is a bit odd but I couldn't find any other way!! -->
                    <t t-set="pages" t-value="dict((l.id, l.page_id.title) for l in user_input.user_input_line_ids).values()" />
                    <!-- Then print the score per each page -->
                    <t t-set="previous" t-value="void" />
                    <t t-foreach='pages' t-as='p'>
                        <t t-if="p != previous">
                        <t t-set="page_score" t-value="sum([(uil.quizz_mark or 0.0) if uil.page_id.title == p else 0.0 for uil in user_input.user_input_line_ids])" />
                        <div> You scored <t t-esc="page_score" /> points in page <t t-esc="p" />.</div>
                        </t>
                        <t t-set="previous" t-value="p" />
                    </t>

The result Of The code - 2

Thank you so much for your help @MICROCOM ^^

Answer 2

One alternative way is to use pure qweb rather than function field; like this:

<!-- First finding which page is related to the survey. This is a bit odd but I couldn't find any other way!! -->
<t t-set="pages" t-value="dict((l.id, l.page_id.id) for l in user_input.user_input_line_ids).values()" />

<!-- Then print the score per each page -->
<t t-foreach='pages' t-as='p'>
    <t t-set="page_score" t-value="sum([(uil.quizz_mark or 0.0) if uil.page_id.id == p else 0.0 for uil in user_input.user_input_line_ids])" />
    <div> You scored <t t-esc="page_score" /> points in page <t t-esc="p" />.</div>
</t>

I have not tested this code but logically it seems to work fine.
