how to make group A "readonly" for "field_x" and group B "editable" for the same "field_x"?

Question

.py file:

....

field_x=fields.Char("Name")

....

in xml file:

....

<name="field_x" groups="A" readonly="1"/>

<name="field_x" groups="B" />

....

I have tried to set it like this, but group A will see nothing forever even if group B has changed the "field_x";

in the fact I just want to group A can read the "field_x" rather than write it and group B can both read and write it; shall I ?

in addition, I also want to get this effect: once the "field_x" is filled by something, nobody can edit again. shall I?

You need to create two XML views.
The first one contains *field_x* once, and is for the least restrictive permissions - read/write - group B.
The second one contains *field_x* once, and is for the most restrictive permissions - read.
Give the second XML view a higher priority than the first, and use the groups tag ON THE VIEW to restrict it just to those in the first group.  You don't need to use the groups tag on the field in either view if you do it this way.
Take a look at *res.partner.prope
