Displaying a nested field as a label

Rails
1

There is what I’m doing: I want to display a series of text_area
fields (read only) of which each has a checkbox.

Is this the best way to do it?

<% form_for (@section), :url =>{:action => “save_comments”} do |f| %>
<% f.fields_for :comments do |a|%>


  • <%= a.text_area :text, :read_only => ‘true’ %>

    <%= a.check_box :approval_boolean %>



    • <% end %>
    <% end %>

    Is there any other way to display the field “text” other than above?

    Thanks!

    If it is going to be read-only, why do you need to display it in a
    text_area instead of directly on the page?

    That’s my question! How do you do that.

    <% a.text %> gives me this error:

    NoMethodError in Sections#edit_acknowledgments

    Showing app/views/sections/edit_acknowledgments.html.erb where line
    #11 raised:

    <%=h a.text %>

    BTW, “a” is not a very helpful name for a block variable (or any
    variable for that matter). Assuming you’re not paying for your code by
    the byte, it would be more legible thus:

    <% f.fields_for :comments do |comment|%>
    …
    <%=h comment.text %>

    YMMV

    You want just
    <%= text %>
    or probably
    <%= h text %> dependant on where text is coming from

    Ok, I’ll clean up the variable names. Thanks! :slight_smile:

    However…

    <%=h comment.txt %> undefined method text' <%= text %> and <%=h text %> give undefined local variable or method text’

    Neither of those ideas work. :frowning:

    Well what is your “a/comment” variable? Have you debugged it to see
    what’s going on in that block? Do you know what methods it’s got, or
    are you assuming there’s a “text” method?

    You can use <% puts … %> or <% logger.info … %> to output
    messages to help you diagnose what’s going on. Personally, I prefer to
    use breakpoint debugging in Netbeans.

    does ‘puts a.respond_to(“text”)’ display true?
    what does ‘puts a.inspect’ give you?

    This is a nested model form using to models: section and comment,
    where section has many comments.

    “text” is a field for comments
    “approval_boolean” is a field for comments

    I just want the field value for “text” to show up as a non-form-
    element and “approval_boolean” to show as a check box form element.

    The code above works, but I can only get the “text” field to show up
    as a text_area or text_field form element.

    Like I said, if <%= a.text %> worked, I’d be happy… but it gives me
    a method error and I’m not sure why.

    Ahhhh! a.class = formbuilder. I thought it was a Comments class.
    Now I know what to look up… I guess my question after all is there
    any way to “extract” a data value from a field within a formbuilder?
    (if I got my terminology right)

    Thanks for taking the time to look at this, btw.

    That’s exactly what I was looking for!

    THANK YOU!

    And thanks for the insight.

    a.object.text
    (although I’m using Formtastic “SemanticFormBuilder” objects here, so
    have fingers crossed the method is the same - dumping “a.methods”
    would help you a little if ‘object’ doesn’t work…)
