ruby on rails - missing required keys: [:id] when updating a nested element -


first of lot helping me out.

i working on project tool, have project model has_many project_tasks. project_tasks belongs project.

i trying make mark complete action project tasks, can't seem project_task id in patch action.

here routes: (note have complete action project too, working fine)

resources :projects     resources :project_tasks       member         patch :complete       end     end     member       patch :complete     end   end

rake routes

complete_project_project_task patch  /projects/:project_id/project_tasks/:id/complete(.:format) project_tasks#complete         project_project_tasks    /projects/:project_id/project_tasks(.:format)              project_tasks#index                               post   /projects/:project_id/project_tasks(.:format)              project_tasks#create      new_project_project_task    /projects/:project_id/project_tasks/new(.:format)          project_tasks#new     edit_project_project_task    /projects/:project_id/project_tasks/:id/edit(.:format)     project_tasks#edit          project_project_task    /projects/:project_id/project_tasks/:id(.:format)          project_tasks#show                               patch  /projects/:project_id/project_tasks/:id(.:format)          project_tasks#update                               put    /projects/:project_id/project_tasks/:id(.:format)          project_tasks#update                               delete /projects/:project_id/project_tasks/:id(.:format)          project_tasks#destroy              complete_project patch  /projects/:id/complete(.:format)                           projects#complete                      projects    /projects(.:format)                                        projects#index                               post   /projects(.:format)                                        projects#create                   new_project    /projects/new(.:format)                                    projects#new                  edit_project    /projects/:id/edit(.:format)                               projects#edit                       project    /projects/:id(.:format)                                    projects#show                               patch  /projects/:id(.:format)                                    projects#update                               put    /projects/:id(.:format)                                    projects#update                               delete /projects/:id(.:format)                                    projects#destroy

the view:

<%= link_to '', complete_project_project_task_path(@project, project_task.id), class: "glyphicon glyphicon-ok", id: "complete-#{project_task.id}", method: :patch %>

and controller action:

def complete     @project = project.find(params[:project_id])     @project_task = project.project_task.find(params[:id])     if @project_task.completed_at.blank?       @project_task.update_attribute(:completed_at, time.now)       flash[:success] = 'task completed!'       redirect_to root_path     else       @project_task.update_attribute(:completed_at, '')       flash[:info] = 'task updated!'       redirect_to root_path     end   end

the error getting : no route matches {:action=>"complete", :controller=>"project_tasks", :id=>nil, :project_id=>"26"} missing required keys: [:id]

in link_to add 2 arguments, @project (to project id) , project_task.id. seems getting project id correct, not project_task.id. tried change controller action @project_task = projecttask.find(params[:id]) without luck. (i tried few things out different arguments in link_to) not sure how retrieve that, hope 1 of can point me in right direction.

thanks in advance!

it looks project_task variable in view not correctly set up. code should this:

<% @project.project_tasks.each |project_task| %>   <%= link_to '', complete_project_project_task_path(@project, project_task.id), class: "glyphicon glyphicon-ok", id: "complete-#{project_task.id}", method: :patch %> <% end %>

(this considers project model has_many :project_tasks).

if setting correctly, can provide complete view , controller action?

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
