routing - Unable to create posts in rails forum on the topics page -


i new rails , trying create forum. forum has many topics, topics belong forum , have many microposts, , microposts belong both topics , users. however, no matter try, posts not created. when try post, routing error "no route matches [get] "/topics""

my routes.rb file:

resources :users  resources :sessions, only: [:new, :create, :destroy] resources :microposts, only: [:create, :destroy] resources :forums, only: [:index, :show] resources :topics, only: [:show]

_micropost_form.html.erb

<%= form_for(@micropost) |f| %> <%= render 'shared/error_messages', object: f.object %> <div class="field">     <%= f.hidden_field :topic_id, value: @topic.id %>     <%= f.hidden_field :user_id, value: current_user.id %>     <%= f.text_field :summary, placeholder: "one-line summary..." %>     <%= f.text_area :content, placeholder: "compose new post..." %> </div> <%= f.submit "post", class: "btn btn-large btn-primary" %> <% end %>

microposts_controller.rb

class micropostscontroller < applicationcontroller before_action :signed_in_user, only: [:create, :destroy] before_action :correct_user, only: :destroy  def create     #@topic = topic.find_by_id(params[:topic_id])     @micropost = current_user.microposts.build(micropost_params)     if @micropost.save         flash[:success] = "your solution has been posted!"         redirect_to topic_path(@topic)     else         redirect_to topic_path(@topic)     end end  def destroy     @micropost.destroy     redirect_to root_url end  private      def micropost_params         params.require(:micropost).permit(:summary, :content, :user_id)     end      def correct_user         @micropost = current_user.microposts.find_by(id: params[:id])         redirect_to root_url if @micropost.nil?     end end

as can see, commented out first line in create function because i've tried posting based on the micropost's relationship topic no avail. in advance , let me know if if posted more code!

in :topics resource, didn't defined index method, that's why won't able topic's list or index page. try change route this:

resources :topics, only: [:index, :show]

or remove attribute resources, automatically include methods default.

resources :topics

also if have relationship between models, should define nested routes in routes file, example, can define them this, can change them accordingly:

try change route file this:

resources :users  resources :sessions, only: [:new, :create, :destroy]  resources :forums   resources :topics     resources :microposts, only: [:new, :create, :destroy]     end end

in above case, can access forums this:

 http://localhost:3000/forums

you can access topics this:

 http://localhost:3000/forums/id/topics

you can access microposts this:

 http://localhost:3000/forums/id/topics/id/microposts

if want access /microposts directly have put outside resource.

resources :microposts, only: [:index]

now able access it:

 http://localhost:3000/microposts

hope help. thanks.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
