Question

I have an association between a project and a task.

A project has_many taks and a task belongs_to a project.

My model is working great. I can create tasks from project and so on.

My problem comes when I want to add a button on the project index view to add task to a
project.

What I want is something like that

(project index view)

Project 1 Show, edit, destroy, add_task

Project 2 Show, edit, destroy, add_task

So that when I click add_task of project 1 I’m redirected to a new task form to create a task for that project.

I’ve added <%= link_to ‘add_task’, new_task_path(:project_id =>
project) %> in the project index view, so when I click on add_task, it redirects me to /task/new?project_id=1

but when I submit the task, the task is not linked to the project.

How can I get the project_id?

Does anyone has a tutorial or an example of how should I do?

Thanks,

Like Oscar suggested you might want to add an extra field in your form which submits the project_id to the params. then in either ur update or create function you can create the record using the parameter value, although on an hidden field make sure u set the value correctly.

<%= f.hidden_field :project_id, :value => project.id%>
