Plugin computed custom field

Added by linkem itsystem over 6 years ago

Hi, I have installed the computed custom field plugin and I'm trying to calculate a time interval; anyone know if it's possible, and how i can calculate difference between two date fields?

This is my environment:
Redmine version 3.4.6.stable
Ruby version 2.4.4-p296 (2018-03-28) [x64-mingw32]
Rails version 4.2.8

Actually, when I try to save a new date custom field with computed option active and minus operator between two date custom fields, I receive this message: Formula undefined method `-' for nil:NilClass.

Thank you all for the support.

I have the same issue. Did you solve it?

Hi, can you give us the source code you typed in the formula ?
On which Model do you use the computed custom field ? issues ?

RE: Plugin computed custom field - Added by Matteo Turra almost 5 years ago

I tried an integer custom field on issues with

self.project_id

formula or simply with

1+1

, but the field on the issue is always null.

Hi,

Can you make a test with a Text Format Custom Field and use in the formula :

self.inspect

And give the result ?

I think you have to test on nil because when creating the Custom Field, the issue attached is probably totally blank :
```
(self.updated_on - self.created_on) if self.updated_on && self.created_on
```

No result with

self.inspect

Hi,

What do you mean ?
You could add a new Text custom field, and you edited an issue and the result in the custom field is empty, instead of having a description of the issue object ?

Aside from that, the solution with the test should work.

OK, I didn't understand the fields are computed on saving issue, not during the view phase.
Sorry.

So all is ok for you ? We can close this issue ?

RE: Plugin computed custom field - Added by Matteo Turra almost 5 years ago

Yes. Thanks.
May be in the docs you could specify this behavior.

I'm not the maintainer of this plugin :-)

May be in the docs you could specify this behavior.

It's written in the readme : A valid formula is a valid Ruby code executed when a customized object is updated.

Hi Jérôme BATAILLE,
The output we get according to your formula in is what time unit ??
