Premise: I am a programmer, but not with Python. I worked only two times with Odoo. A client of mine uses Odoo (a choice I didn't recommend, because I don't understand it ), and asked me to try adding a custom filter in the Odoo dashboard (I think 17), I have access to Odoo.sh, JupyterLab and a test environment. From what I understand, by default The Board / Dashboard /Spreadsheets (I don't know the differences) offers the possibility to filter only by time periods like: 'last 30 days', by month, by year, etc. Actually, it's not a complete thing. In fact, I was asked to be able to add a filter by dates like, start date to end date period. I tried to do some research on the web and with AI, but I couldn't. If someone could help me, I would be grateful. I tried this: /src/odoo/addons/board/ Edited: /models/board.py Added: line 12: date_start = fields.Date(string="Start Date") line 13: date_end = fields.Date(string="End Date") line 25: @api.model line 26: def get_dashboard_data(self, domain=None): line 27: if self.date_start and self.date_end: line 28: domain = domain or [] line 29: domain.extend([('date', '>=', self.date_start), ('date', '<=', self.date_end)]) line 30: return super(BoardBoard, self).get_dashboard_data(domain) Edited: /views/board_view.xml Added: line 10: <group> line 11: <field name="date_start"/> line 12: <field name="date_end"/> line 13: </group> Continue reading...
