AttributeError: 'related' object has no attribute 'selection'

File "/opt/odoo/v8/openerp/models.py", line 243, in __init__

This is because the related selection field has store=True. In that case, you need to indicate the full list of selection options in the field.

[liebendkl]

_columns = {
    'travel_state': fields.related(
    'travel_id', 'state', type='selection', string='State'),
}

how to do that for example in that case?

[liebendkl]

Hello, we need a help with these issue , because we cant install module to see is that what we are looking for. as i think problem is in travel_passenger.py???

[pedrobaeza]

I have indicated the proper solution. Can you do it and make the corresponding PR?

[mjb2000]

Hi @pedrobaeza - I am also having this problem. Could you talk me through the solution you have indicated. I am new to this, so your references to store=True don't mean anything to me at the moment.

Many thanks

[pedrobaeza]

You have to add selection argument with the list of tuples (db_value, label). For example, ...selection=[('1', 'One'), ('2', 'Two')]...

[mjb2000]

Thanks for your quick reply. Where do I add this and to what file?

[pedrobaeza]

To the field where there are the problems.

[mjb2000]

Sorry - I should explain that I litterally installed Odoo for the first time around 60 minutes ago, so I have no idea what 'field' is causing the problem.

I have installed on Debian and within the web interface gone to Settings > Apps and searched through the entire list to find 'Travel' - When I install it, this is the error I get.

Should I be installing the Travel add-on differently?

At this stage I am just doing an early evaluation of Odoo to see if it might work with what I've got planned.

[mjb2000]

I have just tried a second installation, this time on Windows, but I got the same error:

[metamoof]

I'm also having this issue, attempting to evaluate odoo 8 apps

[mjb2000]

It's a shame. The descriptions of the functionality I have read elsewhere sound perfect, but unfortunately it seems that the support for newcomers to implement anything is extremely limited.

If anyone is able to explain how to install this module I would really appreciate it :)

[yvaucher]

@bwrsandman @ehdem Did you see this issue?

[yvaucher]

Error seems to come from there:

https://github.com/OCA/vertical-travel/blob/8.0/travel/travel_passenger.py#L42-43

And it needs same list as in

https://github.com/OCA/vertical-travel/blob/8.0/travel/travel.py#L54-59

[bwrsandman]

This issue is due to the fact that the travel modules have not been ported to 8.0 from 7.0.

This has not yet been planned. The porting, though should not be difficult as these modules don't really touch that many other modules.

[bwrsandman]

Initial port to 8.0 is available in #28 Feel free to test that version

[mjb2000]

Hi @bwrsandman, thanks for taking a look at this. Should I be able to install this via the UI, or do I need to download a zip from GitHub and add it to my Odoo install somewhere?

How do I download a zip of your #28 version?

Thanks

[yvaucher]

@mjb2000 You can get the change of the pull request #28 by doing

git clone git@github.com:oca/vertical-travel
git pull origin pull/28/head

Otherwise you can see the branch name on top of the Pull request: savoirfairelinux:8.0-travel-port Thus go on https://github.com/savoirfairelinux/vertical-travel/tree/8.0-travel-port and download it from there

[bwrsandman]

@mjb2000 You can also download it via https://github.com/savoirfairelinux/vertical-travel/archive/8.0-travel-port.zip

Let us know if you have any issues with that module in #28

Note that it's only the base module that was ported. A dev will need to put time to port the rest.

[mjb2000]

Thank you. I unziped the travel folder to the 'addons' folder and then went ahead with the install. I am still getting the same error, but I am not sure if this is because of one of the other module dependencies failing, or if the install process is downloading the content from GitHub rather than using the update I had extracted to the addons folder?

[bwrsandman]

@mjb2000 is this on a new database or the same as where the error occured before?

More to the point, do you have any other travel* modules installed. They might be the cause of the issue due to them being unported.

[bwrsandman]

This issue should be fixed with the travel module being ported to 8.0
