Unable to pass current_user.name as an attribute for comment

Workaround for the below:

    <%= f.label :Commenter %><br>
    <%= f.text_field :commenter, :value => current_user.name %>

This works for passing the username to the commenter attribute without having to type it in - with the addded bonus of being able to edit it if necessary!

I am trying to make my website show the name of the user who created a comment. In order to do this, I would like the commenter (attribute of comment) to be assigned as current_user.name.

comment has attributes commenter, body, and expdate.

Is it possible to pass current_user.name to the comment.create method through the form?

I've tried this:

<div>
    <%= form_for([@project, @project.comments.build]) do |f| %>
        <br>

        **<%= @commenter = current_user.name %>**

        <%= f.label :Comment %><br>
        <%= f.text_area :body %>
        <br>
        <%= f.label :'Expected Date' %><br>
        <%= f.date_select :expdate %>
        <br>
        <br>
        <%= f.submit %>
    <% end %>
</div>

Where I assigned the commenter attribute to be current_user. Does this not pass that to the create method?

I have also tried assigning it in the comments_controller like this:

def create
    **@comment.commenter = current_user.name**
    @project = Project.find(params[:project_id])
    @comment = @project.comments.create(comment_params)
    redirect_to project_path(@project)
end

But I get an error complaining that commenter is not a defined method.

Both of the methods I tried don't allow me to create a comment, does anyone have any ideas of how I might do this? Many thanks in advance!

In the controller, like this:

def create
  @project = Project.find(params[:project_id])
  @comment = @project.comments.create(comment_params)
  @comment.commenter = current_user.name
  redirect_to project_path(@project)
end

And in the view:

<% @project.comments.each do |comment| %>
  <tr>
    <td><%= comment.body  %></td>
    <td><%= comment.commenter %></td>
    </td>
  </tr>
<% end %>

You can do this in the create method in your controller:

@commenter = current_user.name

It's that simple. And if you need to access the commenter name in your view, add this to your comment class:

def commenter(user)
  user.name
end

Then in your view: 

<%= @comment.commenter(current_user) %>

If you're trying to set @comment.commenter, you will have to define the relation between the two models. Not sure exactly what you're trying to accomplish, but more info about Active Record associations can be found here: http://guides.rubyonrails.org/association_basics.html
