Question

I have a Client model that can have many Projects.

These are my view files:

edit.html.erb

<%= form_for(@project) do |f| %>
  <%= render 'fields', :f => f %>
  <%= f.submit Create %>
<% end %>

_fields.html.erb

<div>
    <%= f.label :name %><br/>
    <%= f.text_field :name %>
</div>
<div>
    <%= f.label :client_id %><br/>
    <%= f.select(:client_id, current_user.client_names) %>
</div>

This is easy and works great.

But is there a way to create a Project from within a Client view as well?

For example on the client edit page it would be nice to have a link New Project for this Client that leads to the above New Project form, but with the respective client preselected in the select box.

Can this be done somehow?

I can’t seem to find a way to pass the Client ID to the New Project form.

Thanks for any help!

Answer 1

This is certainly possible, but requires passing the client id to the new_projects_path. This can be done by nesting the routes to projects inside of clients, or just appending the client id. The difference would be URLs that look like the following:

/clients/1/projects/new
- or -
/projects/new?client_id=1

In your projects controller, you should be able to instantiate the @project variable with a preselected client:

@project = Project.new :client_id => params[:client_id]
