[web2py] eb2py: custom forms can not edit anymore after submitting

[Silvian Cedru]

I am working on a custom project in web2py and I am facing one problems I 
can not edit submitted data anymore for some reason.

Controller:

@auth.requires(auth.has_membership(group_id = 'admin') or 
auth.has_membership(group_id = 'project_manager'))
def update():
 
    # select project from table and save in variable projects
    project_selected = db.projects(request.args(0, cast=int)) or 
redirect(URL('view'))
    #db.post.projects_id.default = project_selected.id
    
    # create form for projects table and initiate with selected project
    form = SQLFORM(db.projects, project_selected)
    
    # create form for activity table
    form_activity = SQLFORM(db.activity)
    if form_activity.process().accepted:
        response.flash = T('Record Updated')
    else:
        response.flash = T('Please complete the form')
    
    # select all activities for the selected project and save in variable
    activities_project = db(db.activity.projects_id == 
project_selected.id).select(orderby=db.activity.id)
    
    return dict(form=form, form_activity=form_activity, 
 projects=project_selected,  activities_project=activities_project)

View:

 <div class="tab">
      <button class="tablinks" onclick="tab(event, 'Overview')" 
id="defaultOpen">Overview</button>
      <button class="tablinks" onclick="tab(event, 'Team')">Team</button>
