I have a problem with a has_many through association. Somehow u.groups.create!(:name => "test group", :school => "the school") makes a correct insert with the trace:
(0.1ms) begin transaction SQL (4.5ms) INSERT INTO "groups" ("created_at", "findeble", "name", "school", "updated_at") VALUES (?, ?, ?, ?, ?) [["created_at", Tue, 01 Oct 2013 08:13:36 UTC +00:00], ["findeble", false], ["name", "test group"], ["school", "the school"], ["updated_at", Tue, 01 Oct 2013 08:13:36 UTC +00:00]] SQL (0.3ms) INSERT INTO "usergroups" ("created_at", "group_id", "updated_at", "user_id") VALUES (?, ?, ?, ?) [["created_at", Tue, 01 Oct 2013 08:13:36 UTC +00:00], ["group_id", 7], ["updated_at", Tue, 01 Oct 2013 08:13:36 UTC +00:00], ["user_id", 1]] (0.5ms) commit transaction => #
But when I try via the groups_controller
# GET /groups/new
# GET /groups/new.json
def new
@group = current_user.groups.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @group }
end
end
def create
@group = current_user.groups.new(params[:group])
respond_to do |format|
if @group.save
format.html { redirect_to @group, notice: 'Group was successfully created.' }
format.json { render json: @group, status: :created, location: @group }
else
format.html { render action: "new" }
format.json { render json: @group.errors, status: :unprocessable_entity }
end
end
end
This creates the trace:

This only creates a new group record and not a record in the joined table. I cant understand what makes this difference.
