First, there is some slight differences with the given example derived from ChangeStateFormView: for entity edition it seems that I have to overwrite the EditionFormView class of cubicweb.web.views.editforms, is that correct?
> After, it seems that EditionFormView does not have this convenient method, get_form(), that returns the current entity form. In place of I found a render_form() method, which controls the rendering of the form. My problem is that I just want to add some formfields and not rewrite the whole thing... How do I proceed?
The EditionFormView class provides the init_form method for this purpose (given
the selected form as argument, does nothing by default). So you can override
it and add desired fields there, that should do the trick. At some point, we
shall probably unify those get_form / init_form mecanism (my preference going
to get_form which is the most flexible).
