for example, when go users/invitations/new , field :email . i'd invite user and, in addition providing email, provide: first_name last_name role company ( user belongs_to company ) i created users::invitationscontroller < devise::invitationscontroller : class users::invitationscontroller < devise::invitationscontroller private def resource_params params.permit(user: [:email, :invitation_token, :role, :company_id])[:user] end end and added fields users/invitations/new . invitation sends fine, when accept , input password, validation fails saying no role selected (b/c of validation). how can set these fields before sending invite , have them persist , save when invite accepted? thanks! rails 5 here solution using accepts_nested_attributes_for . if custom attributes directly on user model should able replace profile_attributes: [:first_name, :last_name] :first_name, :last_name, :role, :company . here controller. class invitations

when asked dependency injection in scala, quite lot of answers point using reader monad, either 1 scalaz or rolling own. there number of clear articles describing basics of approach (e.g. runar's talk , jason's blog ), didn't manage find more complete example, , fail see advantages of approach on e.g. more traditional "manual" di (see the guide wrote ). i'm missing important point, hence question. just example, let's imagine have these classes: trait datastore { def runquery(query: string): list[string] } trait emailserver { def sendemail(to: string, content: string): unit } class findusers(datastore: datastore) { def inactive(): unit = () } class userreminder(finduser: findusers, emailserver: emailserver) { def emailinactive(): unit = () } class customerrelations(userreminder: userreminder) { def retainusers(): unit = {} } here i'm modelling things using classes , constructor parameters, plays nicely "traditional" di appro

let's have basic td_tag helper wraps content_tag method in application_helper.rb def td_tag(*args) if block_given? content_tag(:td, *args) yield end else content_tag(:td ,*args) end end what ruby-way of making code shorter? this example works, in way, doesn't seem nessesary call same function same parameters, , without block? by appending block_given? yield row inside block doesn't work, since have given next function block work with. accept block argument , pass through. no need use block_given? . this functionally identical code: def td_tag(*args, &block) content_tag(:td, *args, &block) end it's safe; if not give method block, block nil , block_given? inside content_tag false.

i have tried this, @ positions, object, in case, imageview , "teleport" degree. how can make not choppy , follow mouse cursor in javafx scene? i did in blog post how create heat seeking missile . the relevant part code fragment: public void move() { spritebase follower = this; if( target != null) { //get distance between follower , target double distancex = target.getcenterx() - follower.getcenterx(); double distancey = target.getcentery() - follower.getcentery(); //get total distance 1 number double distancetotal = math.sqrt(distancex * distancex + distancey * distancey); //calculate how move double movedistancex = this.turnrate * distancex / distancetotal; double movedistancey = this.turnrate * distancey / distancetotal; //increase current speed follower.dx += movedistancex; follower.dy += movedistancey; //get total move distance double totalmove = math.sqrt(follower.dx * follower.dx + fol

according gtk documentation can create combobox with: gtkwidget * gtk_combo_box_new () gtkwidget * gtk_combo_box_new_with_entry () gtkwidget * gtk_combo_box_new_with_model () gtkwidget * gtk_combo_box_new_with_model_and_entry () gtkwidget * gtk_combo_box_new_with_area () gtkwidget * gtk_combo_box_new_with_area_and_entry () i have found lot of examples gtk_combo_box_new_with_model can't find related use of gtk_combo_box_new_with_area . the langage used doesn't matter. something (pygobject): from gi.repository import gtk area = gtk.cellareabox() combo = gtk.combobox.new_with_area(area=area) cell = gtk.cellrenderertext() area.pack_start(cell, true, true, true) you can add more cellrenderers box (which gtk.box) , whatever need those.
