how to implement a section block in eLearning module - odoo 14 - odoo

Question

i was tryin to add a section block which allows me to block all the possible sections (except for the first) and then if all the slides in the section are complete, makes the next one available
I tried with the templates but it don't seem the way to approach this problem cause I cannot find any way to check the previous slides, I was trying to figure it out with javascript maybe but I'm not that good with JS
that's my actual progress:
<odoo>
<data>
<template id="section_lock" inherit_id='website_slides.course_slides_list_slide'>
<xpath expr="//div[#class='text-truncate mr-auto']" position="replace">
<div class="text-truncate mr-auto">
<a t-if="slide.is_preview or slide.previous_category_complete is False or channel.can_publish"
class="o_wslides_js_slides_list_slide_link" t-attf-href="/slides/slide/#{slug(slide)}">
<span t-field="slide.name"/>
</a>
<span t-else="">
<span t-esc="slide.name"/>
</span>
</div>
</xpath>
</template>
</data>
and then the model with the flag needed for the check
class Slide(models.Model):
_inherit = 'slide.slide'
previous_category_complete = fields.Boolean(default=True)
how do u suggest to do it? I think i'm way off th road with this

Answer 1

The relationship between an e-Course and its section is based on the same model (slide.slide) using these relational fields :
category_id = fields.Many2one('slide.slide', string="Section", compute="_compute_category_id", store=True)
slide_ids = fields.One2many('slide.slide', "category_id", string="Slides")
#api.depends('channel_id.slide_ids.is_category', 'channel_id.slide_ids.sequence')
def _compute_category_id(self):
self.category_id = False # initialize whatever the state
channel_slides = {}
for slide in self:
if slide.channel_id.id not in channel_slides:
channel_slides[slide.channel_id.id] = slide.channel_id.slide_ids
for cid, slides in channel_slides.items():
current_category = self.env['slide.slide']
slide_list = list(slides)
slide_list.sort(key=lambda s: (s.sequence, not s.is_category))
for slide in slide_list:
if slide.is_category:
current_category = slide
elif slide.category_id != current_category:
slide.category_id = current_category.id
To know wether a specific student has attended an e-course, there is an existing field in the model 'slide.slide.partner':
class SlidePartnerRelation(models.Model):
_name = 'slide.slide.partner'
slide_id = fields.Many2one('slide.slide', ondelete="cascade", index=True, required=True)
partner_id = fields.Many2one('res.partner', index=True, required=True, ondelete='cascade')
completed = fields.Boolean('Completed')
So you can check wether all the previous Slide Sections are completed for the current partner_id, inheriting the class WebsiteSlides located in website_slides/controllers/main.py > def channel(...)... :
from odoo.addons.website_slides.controllers.main import WebsiteSlides
class WebsiteSlidesCustom(WebsiteSlides):
#http.route()
def channel(self, channel, category=None, tag=None, page=1, slide_type=None, uncategorized=False, sorting=None, search=None, **kw):
res_super = super(WebsiteSlidesCustom, self).channel(channel, category=None, tag=None, page=1, slide_type=None, uncategorized=False, sorting=None, search=None, **kw)
values = res_super.qcontext
sections_completion = request.env['slide.slide.partner'].sudo().search([
('channel_id', '=', current_channel_id),
('is_category','=', True),
('partner_id', '=', request.env.user.partner_id.id)
])
dic_sections_completion={}
for sec in sections_completion.sorted('sequence'):
dic_sections_completion[sec.id] = sec.completed
values['sections_completion'] = dic_sections_completion
return request.render('website_slides.course_main', values)
in your module directory views, create a new xml file : course_main_custom.xml
<template id="course_main_custom" inherit_id="website_slides.course_main" name="Course Main" >
<xpath expr="//t[#t-set='category']" position="after">
...
</xpath>
</template>
