uid not supported in attrs in web client only

[Sebastien LANGE - http://www.Syleam.fr]

In GTK client rev 1016, the uid is supported in attrs but not web client.

Thanks

Hello Sebastien,

We have applied attrs attribute with button tag for uid like:
<button colspan="2" name="483" string="Select Invoices to Pay" type="action" attrs="{'invisible':[(uid,'=',1)]}"/>

When i connect using uid=1 then button is display on gtk form it means gtk also does not support uid on attrs...so please give us example how you set uid with attrs. So that we can test on both gtk and webclient.

Thanks.

Hi sma

You can test this on the crm.case object like

<field name="priority" attrs="{'readonly': [('user_id','!=', uid)]}"/>

Only the user who is affect to this case can change the priority

Web client only supports basic expressions (should be compatible with JavaScript) and values will be evaluated against current view fields. As `uid` in this expression is not a defined field in the view, it won't get evaluated (in gtk it's evaluated by python code, while in web client it's JavaScript) so some python specific expressions/vars are not available in web client, like `uid, date, context` etc.

For workaround to this problem, you can define a hidden (invisible) field `uid` and setting it's default value to current `uid` in the view.

Hi

Sorry but i think this issue must be fix, it works for context and domain and why not in attrs ?

And this issue works with the GTK client, the both clients must be have the same features.

In our case, we use readonly in attrs (not only invisible)

In order to implement the feature (python expression evaluation), we need to send request (ajax) to server (web server) every time which might be slow for `attrs` (intended for quick UI changes).

The original requirement of the attrs feature (attrs first implemented in eTiny) are to enable quick UI changes using simple JavaScript compatible expressions based on the current form state.

This is not a bug but a design limitation of the web client feature...

Hello,

I understand the limitation due to the lack of a Python runtime in the
browser. However, I think it's possible to work a bit more on the Javascript
expression parser in order to change the expression eventually (regexp
replacement eventually) and support a few more basic stuff, time and uid
being included. I'm pretty sure the Javascript and Python syntax are not so
different for the very basic maths operations involved, so defining the
right values in the the expression scope, such as uid and time and
eventually hacking a bit the expression (most basic evaluated requirement)
and eventually making a few basic methods available would improve the
situation a lot, no?

I think that uid and time are so basic things that if they are not supported
the feature loss is too large...

Thoughts?

@rvalyi, yes we can improve the expression evaluation to support common operations, but there might be problem with localized values (date, number etc). I'm marking this bug as wishlist...

`uid` support has been committed in stable 5.0 branch

[Jaf Faizal (jaffaizal)]

I am a newbie. This problem exist in 6.1.1
How to solve it.

Thank you

[Jaf Faizal (jaffaizal)]

Hi Amit,

I'm using v6.1.1 and the problem still exist.

BTW, how to assign the uid to and invisible field in the XML code?

Thanks
