Rails Multiple forms in one view rendering errors issue

I have built a dashboard of sorts with multiple forms from different models in the same view. My goal is to have all of the error messages from each form render on the dashboard. The dashboard is part of the PagesController and the forms belong to other controllers.

All of the forms currently work great. However, when errors occur they render in other views not the dashboard. When I attempt to "render" the errors on the dashboard page I get errors that the other form's models are missing.

Example of "render" that renders outside of the dashboard view.

class NotesController < ApplicationController
    def create
        @note = Note.new(params[:note])
        if @note.save
            flash[:notice] = "Note Created!"
            redirect_to dashboard_path
        else
            flash[:alert] = "Note failed"
            render :action => "new"
        end
    end
 end

The example I would like to work, which renders the errors inside the dashboard view.

class NotesController < ApplicationController
    def create
        @note = Note.new开发者_JS百科(params[:note])
        if @note.save
            flash[:notice] = "Note Created!"
            redirect_to dashboard_path
        else
            flash[:alert] = "Note failed"
            render 'pages/home'
        end
    end
 end

To reiterate, I am trying to make it so all errors will show up on the dashboard page with out breaking the site. Let me know if you would like more information.

You can accomplished this by just setting errors to an instance variable that all the forms use:

class NotesController < ApplicationController
    def create
        @note = Note.new(params[:note])
        if @note.save
            flash[:notice] = "Note Created!"
            redirect_to dashboard_path
        else
            @errors = @note.errors
            load_home
            render 'pages/home'
        end
    end

    private

    def load_home
      @instances = Model.all
      @instance_1 = Model.find(1)
    end
 end

All your controllers would set @errors = @model.errors then in your view you just have something like this instead of relying on f.error_messages or whatever you have in your form: (in haml)

- unless @errors.nil?
  #errorExplanation
    %h2 Please correct these errors
    %ul
      - for e in @errors
        %li= e[1]
