Question

I have the following code:

tasks/_form.html.haml

%h3 
    Tasks
%span.form-inline.centered
    = form_for [@activity, @task], remote: true do |f|
        = f.text_field :description, {placeholder: 'Enter task description and click + to create a new task', class: 'input-task'}
        = f.submit "+", class: 'btn btn-danger'

controllers/tasks_controller.rb

  def create
    activity = Activity.find(params[:activity_id])

    flash[:error] = I18n.t "errors.task.generic" if !activity.add_task!(params[:task])    

    @task = activity.tasks.last

    respond_to do |format|
      format.html { redirect_to activity_path(activity) }
      format.js
    end
  end

tasks/create.js.erb

$('#incomplete-tasks').append("<%= j render partial: 'task', locals: {task: @task} %>");

tasks/_task.html.haml

%li
    = task.description
    = link_to "Done", activity_task_path(task.activity, task: task), html_options = {method: :put, class: 'pull-right'}

The problem that I have is when it tries to use js to render the partial my restful resource activity_task_path sends a get method instead of the put method that I am specifying. If I don’t use js to render it and i just refresh the browser it works fine. I now get a routing error because I do no have a show page. I don’t however need one. I just need it to update my task via a put method. If anybody can shed some light on why this is happening I would appreciate it.

[EDIT1]

If you have any questions or need me to add any code or anything else that I can do to help let me know. I really don’t understand why this is happening. Thank you.

[EDIT2]

  def update
    activity = Activity.find(params[:id])
    activity.update_task!(params[:task])
    redirect_to activity_path(params[:id])
  end

This is my update controller.

You can find the app online at https://trackit.mlpinit.com to get a better understanding of what I am trying to do.

Hopping to make it more clear… Here is the error I get when I add a new task through ajax.

Routing Error

No route matches

 {:action=>"show", :controller=>"tasks", :task=>#<Task id: 64, description: "lalala", complete: false, created_at: "2012-10-11 19:41:22", updated_at: "2012-10-11 19:41:22", activity_id: 6>, :activity_id=>#<Activity id: 6, title: "Lala", description: "this is lala", created_at: "2012-10-10 18:37:18", updated_at: "2012-10-10 18:37:18", user_id: 2, activity_group_id: nil>}

Once again if I don’t do this through an ajax call it works ok. My assumption is that the problem takes place because it doesn’t understand the put method for some reason…

[EDIT5]

If I take of the link from my _task partial the append happens without any errors. I thought I should mention that

[EDIT6]

I will add a visual walkthrough to make sure that I make myself understood…

I have a task form:

I enter a task name

I hit (enter)plus to create it.

I get the following error that is also presented above:

If I hit refresh the task was generated ok:

That is why I believe it has to be in the .js.erb file…

Answer 1

activity_task_path(task.activity, task: task)

activity_task_path expects two id parameters, I think your last is now mixed with the task: task and the post parameters. You also get mixups because of the form_for and trying this method to use ‘update’ for task. You are providing no data fields.

So I think your solution is:

activity_task_path(task.activity, task)
