RAILS3: Pass arbitrary parameters via button_to?

Question

I\'m trying to do something very simple in my first Rails app (Rails 3) and I\'m not sure what I\'m doing wrong, or if there\'s a better approach. Can\'t find anything on th

Answer 1

Just circling back to finish this up. Ultimately I solved this by using link_to but using jQuery to make it look like a button. @kishie, if you're saying you made this work with button_to I'd like to see the code, but as I like jQuery it's solved as far as I'm concerned (for this app, anyway.)

Here's the code in Article#show view. (The class is what makes it look like a button via jQuery.)

<%= link_to "New Request", new_work_request_path(:article_id => @article.id), :class => "ui-button" %>

Here's the code in Work_Request controller's new method:

if !params[:article_id].blank?
  @work_request.article = Article.find(params[:article_id])
end

Then the Work_Request#new view renders it properly.

I just hit a similar issue and I got it to work by passing the parameter as follows:

<%= button_to("Add WorkRequest", new_work_request_path(:article_id => @article.id), :action => "new", :method => :get)%>

Answer 3

In article#show

<%= button_to("Add WorkRequest", {:controller => "work_request", :action => "new", :article_id => @article.id})%>

In work_requests#new

<%= f.text_field :article_id, :value => params[:article_id]%>

If you nest your resources for :work_requests within :articles in your routes.rb, then pass your params[:id] which would be your article_id and add :method => :get to the button_to call, you should be okay.

# config/routes.rb
resources :articles do
  resources :work_requests
end

# app/views/articles/show.html.erb
<%= button_to "Add Work Request", new_article_work_request_path(params[:id]), 
    :method => :get %>

# app/controllers/work_requests_controller.rb
class WorkRequestsController < ApplicationController

  ...
  def new
    @work_item = WorkItem.new
    @article = Article.find(params[:article_id])
    ...
  end

  ...
end

Answer 5

Add this line of code in your routes.rb file.

resources :work_requests do
  member do 
    post 'new'
  end
end

It shouldn't be the GET method because you're sending information to the server, via :module_id. This will then work.

<%= button_to("Add WorkRequest", {:controller => "work_request", :action => "new", :article_id => @article.id})%>
