49. One2many Field In Odoo 15 || Odoo Relational Fields || Odoo 15 Development Tutorials

[@UtsavKumarMalviya]

Nicely explained, I am getting complete form view of base model, however i add only tree view in my one2many field?

[@OdooMates]

if you haven't defined form view for the model, odoo will show auto generated form view for the model

Useful tutorial. I want to know if is it possible to use a specify pricelist for the product price? Let's say if a business requirement is to use a pricelist with ID 2 for products used in pharmacy lines, how could I set this up? Thanks in advance.

Hi Odoo mates thank you for the useful video. Plz share how we can get the latest entered record from one2many fileld in another modules and how to show in view of that other module. Like from this One2many field you created, the last added medicine name only, show it in sale module, just under the Customer name. Plz help

In Odoo14, I keep getting the following error : File "C:\Odoo14\odoo\odoo\models.py", line 5168, in _update_cache raise ValueError("Invalid field %r on model %r" % (e.args[0], self._name)) Exception should I watch the video of Odoo14 tutorial ?

can you show us what code you have recently added

​@@OdooMates Hi, let me explain my scenario: I have two child models B and C _inherit from parent model A. The main model A has a One2many relationship with another model D. The problem occurs when interacting with "field_ids" added to the views of B and C. However, the error does not occur when declaring the One2many relationship field between child model B and D for example! but this does not make sense to me, because in this case model D will have multiple Many2one fields ("B_id" and "C_id"] referring to child models B and C respectively, instead of a single Many2one field "A_id" referring to the main model A, so maybe the One2many relationship is not supported in the _inherit mode?

Hi Odoo mates, thanks for your video tutorials they are really helpful. I noticed some issues even though I followed this video of One2many fields step by step. First, I'm developing on Odoo 16, and when I followed the exact steps in this video, the Add a line section as can been seen in the video @ 11:03, does not display in the UI. Secondly, products lists do not display in the UI as well. Can you help me in getting around this issue? Thanks. Update: I'd like to say that I have been able to figure out what the issue was, and I have had it fixed. Thanks for your time.

[@moatazachour5529]

how do you fixed my friend

[@OdooMates]

Try with super use mode and see how it goes

i have this error while try to add a line "Uncaught Promise > Cannot read properties of undefined (reading 'append') " but it is disappear when I add editable="bottom" in tree tag so what is the problem and this problem every where I try to add a line

[@pranavbhat92]

Thank you for the video! I was able to get the product lists without adding the dependency in the manifest file. Thats weird. 🤔

[@OdooMates]

Glad to hear it

[@pranavbhat92]

@@OdooMates Sorry I spoke too soon. When I added the 'related' field for the price_unit, I started getting the error. After adding the dependency, the error vanished. Once again, thanks for covering everything in detail! 😀

i have a problem with the security file : Exception: Module loading om_hospital failed: file om_hospital\security/ir.model.access.csv could not be processed: No matching record found for external id 'om_hospital.model_appointment_availability_lines' in field 'Model' Missing required value for the field 'Model' (model_id) i got this error when i upgraded the module ..

[@OdooMates]

do you have a model named: appointment_availability_lines in the module and imported the file in init file ?

[@chaotixsniper]

@@OdooMates no i just followed your steps i just changed the naming, instead of appointment_pharmacy_lines i named it appointment_availability_lines.. I have the same models as you in this tutorial.

[@OdooMates]

So you need to set access rights for appointment availability model ?

[@chaotixsniper]

@@OdooMates yeah i did exactly the same way you did and still get the error when i upgrade the module
