Symbols not recognized after nesting routes - NoMethodError in Timesheets#new

For some reason The symbols in my new timesheet form aren’t being recognized after I nested the routes.

I go to: http://localhost:3000/users/1/timesheets/new

and receive the error:

NoMethodError in Timesheets#new

Showing /Rails/timecard/app/views/timesheets/new.html.erb where line #8 raised:

undefined method `user_id' for #<User:0x00000001eb0748>

Extracted source (around line #8):

5: 6: <div class="field">
7: <%= f.label :user_id %><br />
8: <%= f.text_field :user_id %>
9: </div>
10: <div class="field">
11: <%= f.label :time_in %><br />

I have 2 models, Timesheet and User

Timesheet belongs_to :user

User has_many :timesheets

routes.rb:

Perhaps I just have never seen your kind of defining form_for. But I had expected something like:

<%= form_for(@timesheet, :url => user_timesheets_path(@timesheet.user)) do |f| %>

<%= f.label :user_id %>

<%= f.text_field :user_id %>

<%= f.label :time_in %>

<%= f.datetime_select :time_in %>

<%= f.label :time_out %>

<%= f.datetime_select :time_out %>

<%= f.label :comments %>

<%= f.text_area :comments %>

<%= f.submit %>

Your NoMethodError tells us too: it has got a User, but needs a Timesheet…

Sorry, have found your problem:

<%= form_for( [@timesheet.user, @timesheet] ) do |f| %>

It has to be an Array...

<%= form_for( [@timesheet.user, @timesheet] ) do |f| %>

Thank you, you’ve been a HUGE help, just missed where it said it needed to be an array. I’ll be more thorough next time I’m reading the api docs :slight_smile:
