Hi, I'm trying to create a view that allows a user to create a new project and add (existing) users to that project. In order to represent the two tables on a single page, I've been following a recipe from pyslices:
http://www.web2pyslices.com/article/show/1542/manage-users-and-memebership-in-the-same-form So I have a project table and a project_members table and the db and controller functions are below. The structure is subtly different from the slice: that is editing an existing member, so the auth_user id is known and is used in the forms to select relevant records. In my case, I'm trying to create a new project, so neither controller 'knows' the next project table id, and my view shows the SQLFORM to create a new project but then a SQLFORM.grid of *all* members of *all* projects. If it was just the project SQLFORM, it wouldn't be a problem, because project would get the ID automatically on create, but I want to be able to pass the project row ID to the new_project_membership() controller, so that I can get the SQLFORM.grid to show only member of this project (as they are added) and insert it for newly added entries to project_members. So my plan was to get the row ID from the db somehow and pass it on to the new_project_membership() controller. Of course, the deeper issue is that I really want an atomic commit - the project row and project_membership row(s) only go in when a single final submit is pressed, so the answer may be "don't do it like that"! In which case, pointers to the right approach would be really welcome! Thanks, David *Table definitions:* db.define_table('project', Field('title','string', notnull=True), Field('start_date','date', notnull=True), Field('end_date','date', notnull=True)) db.define_table('project_members', Field('project_id', 'reference project', notnull=True), Field('user_id', 'reference auth_user', notnull=True), Field('project_role', notnull=True)) *Controllers:* @auth.requires_login() def new_project(): # set up the project form form = SQLFORM(db.project, fields = ['title', 'start_date', 'end_date' ]).process() # set up a membership panel membership_panel = LOAD(request.controller, 'new_project_membership.html', #args=[project_id], ajax=True) # pass both of those to the view return dict(form=form, membership_panel=membership_panel) @auth.requires_login() def new_project_membership(): # function to return a grid containing a membership panel form = SQLFORM.grid(db.project_members, #args=[project_id], searchable=False, deletable=False, details=False, selectable=False, csv=False) return form *View:* {{extend 'layout.html'}} {{=H2('New project and members')}} <p> Please use the form below to create a new project and add members and roles/</p> {{=H4('Project details')}} <br> {{=form}} <br> {{=H4('Project members')}} <br> {{=membership_panel}} <br> -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
